Description

Technical Field

[0001] The present invention relates to a carbon dioxide emissions calculation system and a carbon dioxide emissions calculation method for calculating the amount of carbon dioxide emissions related to products of a specified type manufactured within a specified period. Background Art

[0002] In recent years, from the viewpoint of global environmental protection and the like, attention has been paid to the amount of carbon dioxide emissions. Technologies related to such carbon dioxide emissions are disclosed, for example, in Patent Document 1. The carbon traceability management system disclosed in the Patent Document 1 includes: a utility management unit that records and manages power received from the outside, received cooling or heating energy, operation results of private power generation equipment, and operation results of cooling, heating, and thermal equipment; a material management unit that records and manages material and raw material usage results; a facility management unit that manages and records the energy used by facility equipment during manufacturing; a manufacturing execution management unit that manages the production results of products; an emissions calculation unit that calculates greenhouse gas emissions based on each of the results recorded and managed in the utility management unit, the material management unit, the facility management unit, and the manufacturing execution management unit; and an emissions allocation unit that allocates the greenhouse gas emissions calculated by the emissions calculation unit to a manufacturing lot that is a unit amount of a product. Among them, boilers, power receiving equipment, private power generation equipment, water supply equipment, etc. are classified as primary power equipment. In contrast, power equipment that operates by receiving energy supply from the primary power equipment is classified as secondary power equipment, and non-power equipment that operates by receiving energy supply from the primary power equipment and the secondary power equipment is classified as tertiary equipment. The emissions allocation unit allocates the greenhouse gas emissions of the product lot based on the usage situation corresponding to the product lot in the tertiary equipment and the usage situation corresponding to the product lot in the secondary equipment. Further, the emissions allocation unit includes an emissions management unit that manages the greenhouse gas emissions allocated to the product lot as the inherent data of the product lot.

[0003] The carbon traceability management system disclosed in the Patent Document 1 can calculate the greenhouse gas emissions per unit amount of a product, that is, for each product lot. However, in order to use the carbon traceability management system disclosed in the Patent Document 1, it is necessary to manage various data required for calculating the greenhouse gas emissions in the system in association with the production lot along the time axis. Without such management, the system cannot be used.

However, the scope of the invention is not limited to the disclosed embodiments. In addition, components given the same reference numerals in the respective drawings are represented as the same components, and their descriptions are appropriately omitted. In this specification, general terms are represented by reference numerals without suffixes, and individual components are represented by reference numerals with suffixes.

[0029] The carbon dioxide emission calculation system in the embodiment is a system for calculating the carbon dioxide emissions (CO2 emissions) related to the target products of the target type in a factory (workshop) that can manufacture multiple types of products through multiple processes. The carbon dioxide emission calculation system includes a raw material emission calculation unit, a main equipment unit emission calculation unit, and a process emission calculation unit. The raw material emission calculation unit calculates the total amount of raw material CO2 emissions related to the raw materials in the manufacture of the target products of the target type based on the first unit CO2 emissions per unit of the raw materials used to manufacture the target products of the target type given (previously assigned, previously prepared), and the total amount of the raw materials used for the target products of the target type manufactured during the specified period. The main equipment unit emission calculation unit calculates the second unit CO2 emissions per unit of each of the multiple main equipment corresponding to the multiple processes for manufacturing the target products of the target type based on the total amount of the manufacturing load applied to the main equipment corresponding to the process and used for performing the process during the manufacture within the specified period, and the total amount of the CO2 emissions of the main equipment related to the total amount of the manufacturing load. The process emission calculation unit calculates the process CO2 emissions in the process performed by the main equipment for manufacturing the target products of the target type for each of the multiple main equipment corresponding to the multiple processes for manufacturing the target products of the target type based on the second unit CO2 emissions per unit of the main equipment calculated by the main equipment unit emission calculation unit, and the total amount of the manufacturing load applied to the main equipment for manufacturing the target products of the target type during the manufacture within the specified period.

[0030] Hereinafter, the carbon dioxide emission calculation system and the carbon dioxide emission calculation method installed in the system will be described in more detail. Here, as an example, a factory (workshop) that can manufacture rolled steel plates of multiple varieties will be described, but the factory (workshop) can be any factory (workshop) as long as it can manufacture multiple types of products through multiple processes. The carbon dioxide emission calculation system can be constituted by communicably connecting an input / output terminal device for inputting and outputting data, one or more calculation processing devices (e.g., server devices) that execute various calculation processes, and one or more database devices that store (manage) various data, or can be constituted by integrally forming at least a part of these input / output terminal devices, one or more calculation processing devices, and one or more database devices, and communicably connecting it with the remaining part. Here, taking the carbon dioxide emission calculation device that integrates all of them as an example, the carbon dioxide emission calculation system will be described.

[0031] Figure 1This is a diagram showing the configuration of a carbon dioxide emissions calculation system (a carbon dioxide emissions calculation device as an example) in an embodiment.

[0032] For example, as Figure 1 shown, the carbon dioxide emissions calculation system (a carbon dioxide emissions calculation device as an example) S in the embodiment includes an input unit 1, an output unit 2, an interface unit (IF unit) 3, a control processing unit 4, and a storage unit 5.

[0033] The input unit 1 is connected to the control processing unit 4 and inputs various instructions such as an instruction indicating the start of CO2 emissions calculation and various data required for the operation of the carbon dioxide emissions calculation device S, such as the manufacturing process of the product and the manufacturing performance of the product, into the carbon dioxide emissions calculation device S. For example, it is a plurality of input switches, a keyboard, a mouse, etc. assigned with specified functions. The output unit 2 is connected to the control processing unit 4 and outputs, under the control of the control processing unit 4, the instructions and data input from the input unit 1, as well as calculation results, etc. For example, it is a display device such as a CRT monitor, an LCD (liquid crystal display device), and an organic EL monitor, a printing device such as a printer, etc.

[0034] In addition, the input unit 1 and the output unit 2 may also be constituted by a touch panel. In the case of a touch panel configuration, the input unit 1 is, for example, a position input device that detects an operation position in a resistive film method or a capacitive method, etc., and performs input, and the output unit 2 is a display device. In this touch panel, the position input device is provided on the display surface of the display device, and candidates for one or more input contents that can be input to the display device are displayed. When the user touches the display position of the input content that the user wants to input, the position is detected by the position input device, and the display content displayed at the detected position is input to the carbon dioxide emissions calculation device S as the user's operation input content. Such a touch panel can provide a carbon dioxide emissions calculation device S that is easy for the user to use because the user can easily and intuitively understand the input operation.

[0035] The IF unit 3 is connected to the control processing unit 4 and, under the control of the control processing unit 4, performs input and output of data with external devices, for example. For example, it is an interface circuit of a serial communication method, i.e., RS - 232C, an interface circuit using the Bluetooth (registered trademark) standard, and an interface circuit using the USB (Universal Serial Bus) standard, etc. In addition, the IF unit 3 may also be a communication interface circuit such as a data communication card or a communication interface circuit that transmits and receives communication signals with external devices following the IEEE802.11 standard, etc.

[0036] The storage unit 5 is a circuit connected to the control processing unit 4 and stores various specified programs and various specified data under the control of the control processing unit 4. Additionally, in one example, the various specified programs are recorded on a recording medium such as a CD-R or DVD-R, and are input from the recording medium via its driving device and the IF unit 3 and stored in the storage unit 5.

[0037] The various specified programs include, for example, a control processing program, which includes, for example, a control program, a raw material emissions calculation program, a main equipment unit emissions calculation program, a process emissions calculation program, an emission allocation calculation program, an incidental processing emissions calculation program, a first remaining emissions calculation program, a second remaining emissions calculation program, and an object product emissions calculation program, etc. The control program controls each of the parts 1 to 3, 5 of the carbon dioxide emissions calculation device S according to the functions of each part. The raw material emissions calculation program is a program for obtaining the total amount of raw material CO2 emissions related to the raw materials in the manufacture of the object products of the object type based on the first unit CO2 emissions per unit of the raw materials used in manufacturing the object products of the object type given, and the total amount of the raw materials used in the object products of the object type manufactured during the specified period. The main equipment unit emissions calculation program is a program for obtaining the second unit CO2 emissions per unit of each of the multiple main equipment corresponding to the multiple processes for manufacturing the object products of the object type, based on the total amount of the manufacturing load applied to the main equipment corresponding to the process and used for performing the process during the manufacture in the specified period, and the total amount of the CO2 emissions of the main equipment related to the total amount of the manufacturing load. The process emissions calculation program is a program for obtaining the process CO2 emissions in the process performed by the main equipment for manufacturing the object products of the object type for each of the multiple main equipment corresponding to the multiple processes for manufacturing the object products of the object type, based on the second unit CO2 emissions per unit of the main equipment obtained by the main equipment unit emissions calculation program, and the total amount of the manufacturing load applied to the main equipment for manufacturing the object products of the object type during the manufacture in the specified period. The emission allocation calculation program is a program for allocating the total amount of the sub-equipment CO2 emissions of the sub-equipment during the specified period to each of the multiple equipment using the sub-equipment in a specified ratio for the sub-equipment that indirectly participates in the manufacture of the product through the main equipment and is used for multiple equipment, so as to obtain the CO2 emission allocation amount of the equipment using the sub-equipment for each of the multiple equipment using the sub-equipment. The incidental processing emissions calculation program is a program for obtaining the total amount of the incidental processing CO2 emissions in the specified processing performed on the object products of the object type based on the third unit CO2 emissions per unit in the specified processing performed on the products from after the manufacture of the products to the delivery to the delivery destination, and the total amount of the object products of the object type manufactured in the factory during the specified period.The first remaining emissions calculation program is a program for calculating the fourth unit CO2 emissions per unit product of the remaining emission sources based on the total amount of remaining CO2 emissions of the remaining emission sources during the specified period and the total amount of products manufactured at the factory during the specified period. The second remaining emissions calculation program is a program for calculating the total amount of the second remaining CO2 emissions related to the remaining emission sources in the manufacture of the target products of the target product type based on the fourth unit CO2 emissions per unit product of the remaining emission sources calculated by the remaining emissions calculation unit and the total amount of the target products of the target product type manufactured during the specified period. The target product emissions calculation program is a program for calculating the sum of the CO2 emissions of each process in the processes performed by the main equipment obtained by the process emissions calculation program for each of the multiple main equipment corresponding to the multiple processes used to manufacture the target products of the target product type, and the total amount of the raw material CO2 emissions related to the raw materials in the manufacture of the target products of the target product type obtained by the raw material emissions total calculation program, and taking this as the total amount of the target product CO2 emissions related to the target products of the target product type.

[0038] The various specified data include the data necessary for executing these respective programs, such as manufacturing process information, product manufacturing performance information, equipment-related performance information, remaining emission source-related performance information, unit emissions information, sub-equipment correspondence information, various calculation results during the calculation, and the final calculation result, etc.

[0039] The storage unit 5 includes, for example, a non-volatile storage element, namely ROM (Read Only Memory), a rewritable non-volatile storage element, namely EEPROM (Electrically Erasable Programmable Read Only Memory), etc. And the storage unit 5 includes a RAM (Random Access Memory), etc., which is the so-called working memory of the control processing unit 4 for storing data generated during the execution of the specified program. In addition, the storage unit 5 may be configured with a hard disk device having a large storage capacity.

[0040] In order to store the manufacturing process information, product manufacturing performance information, equipment-related performance information, remaining emission source-related performance information, unit emissions information, and sub-equipment correspondence information respectively, the storage unit 5 functionally includes a manufacturing process information storage unit 51, a product manufacturing performance information storage unit 52, an equipment-related performance information storage unit 53, a remaining emission source-related performance information storage unit 54, a unit emissions information storage unit 55, and a sub-equipment correspondence information storage unit 56.

Figure 2 A represents a manufacturing process information table for a product with a product No (number) of "P001".

[0042] The manufacturing process information storage unit 51 is used to store manufacturing process information. The manufacturing process information is information (data) showing the manufacturing process of a product for each type of product.

[0043] In the present embodiment, this manufacturing process information is stored in the manufacturing process information storage unit 51 in tabular form. The manufacturing process information table 100 (100a, 100b) registering this manufacturing process information is, for example, as Figure 2 shown, including: a process sequence field 101 (101a, 101b (101b-1, 101b-2)) registering the process sequence; an equipment field 102 (102a, 102b (102b-1, 102b-2)) registering the main equipment for performing the process in the sequence registered in the process sequence field 101, and having a record for each process. The main equipment is the equipment corresponding to the process and used to perform the process, and is appropriately determined according to the product to be manufactured in the factory. In the present embodiment, as described above, since the factory is a factory capable of manufacturing rolled steel sheets of multiple varieties, the main equipment is, for example, a casting equipment, a rolling equipment, a heat treatment equipment, a cutting equipment, etc. In addition, the same type of main equipment can be one or more.

[0044] Also, in the present embodiment, the manufacturing process information table 100 can further register the actual results of each process for the products of this type. The manufacturing process information table 100 further includes: a weight field 103 (103a, 103b (103b-1, 103b-2)) for registering the total amount (actual weight) of the products of this type manufactured by the main equipment for performing the processes in the order registered in the process sequence field 101 within a specified period; and a time field 104 (104a, 104b (104b-1, 104b-2)) for registering the total usage time (total operation time, actual time) required for the main equipment for performing the processes in the order registered in the process sequence field 101 to manufacture the products of this type within the specified period. Moreover, there is a record in which the shipment volume (actual shipment volume, production volume (actual production volume)) of the products of this type is registered in the weight field 103. Here, in the present embodiment, the actual value registered in the weight field 103 of the first process is also the total amount of raw materials used when manufacturing the products of this type within the specified period. In the present embodiment, the manufacturing load of the main equipment is represented by at least one of the manufacturing amount of the products manufactured by the main equipment and the usage time of the main equipment. Therefore, the manufacturing load from the perspective of the manufacturing amount of the products is registered in the weight field 103, and the manufacturing load from the perspective of the usage time is registered in the time field 104.

[0045] Figure 2 Manufacturing process information tables 100a and 100b for each of the two types of products, namely the product of product No. "P001" and the product of product No. "P002", are shown, but of course, manufacturing process information tables are prepared in advance for each product type and stored in the manufacturing process information storage unit 51.

[0046] In addition, in the case where products of the same type can be manufactured through different processes, manufacturing process information tables 100 are created for each of the different processes and stored in the manufacturing process information storage unit 51. For example, as Figure 2As shown in B, the product of product No. "P002" can be manufactured by the first manufacturing process mode and the second manufacturing process mode different from the first manufacturing process mode. The first manufacturing process mode is a mode in which the following processes are sequentially performed: the first process using the main equipment with the equipment name "casting 2", the second process using the main equipment with the equipment name "rolling 2", the third process using the main equipment with the equipment name "rolling 2", the fourth process using the main equipment with the equipment name "rolling 3", the fifth process using the main equipment with the equipment name "heat treatment", the sixth process using the main equipment with the equipment name "coating", and the seventh process using the main equipment with the equipment name "cutting 2". The second manufacturing process mode is a mode in which the following processes are sequentially performed: the first process using the main equipment with the equipment name "casting 1", the second process using the main equipment with the equipment name "rolling 2", the third process using the main equipment with the equipment name "rolling 3", the fourth process using the main equipment with the equipment name "rolling 3", the fifth process using the main equipment with the equipment name "heat treatment", the sixth process using the main equipment with the equipment name "coating", and the seventh process using the main equipment with the equipment name "cutting 2". The manufacturing process information table 102b for the product of product No. "P002" includes the table 102b-1 registering the manufacturing process information of the first manufacturing process mode and the table 102b-2 registering the manufacturing process information of the second manufacturing process mode.

[0047] The product manufacturing performance information storage unit 52 is used to store product manufacturing performance information. The product manufacturing performance information is information (data) showing the manufacturing volume (production volume) of products by each product type within a specified period. The specified period is appropriately set in advance by the user (operator), for example, 10 days, one month, half a year, etc.

[0048] In the present embodiment, this product manufacturing performance information is stored in the product manufacturing performance information storage unit 52 in tabular form. The product manufacturing performance information table 200 registering this product manufacturing performance information is, for example, as Figure 3As shown, it includes a product No. field 201 for registering the product No. of the registered product, a type field 202 for registering the type of the product whose product No. is registered in the product No. field 201, and a production volume field 203 for registering the manufacturing volume (production volume) of the product whose product No. is registered in the in-process product No. field 201 during the specified period, and has a record for each product No. (type of product). The product No. is an identifier for determining and identifying the type of product. In this embodiment, as an example, the types of products are classified according to the specifications of each product. Therefore, the product No. is assigned for each type of product (product specification). In this embodiment, the specifications of the products are classified according to variety and customer (orderer). Even if multiple orders are received at different times, if the variety and customer are the same, the same product No. is assigned to the multiple orders, and the products manufactured according to the multiple orders are grouped together. Therefore, there may be one or more target products of the target type. The variety is the name of the steel plate classified and assigned according to the composition of each steel plate. In addition, the variety can also be classified from the perspective of including the strength and size of the product depending on the manufacturing process. Therefore, in this embodiment, the type field 202 includes a variety field (variety sub-field) 2021 for registering the variety and a customer field (customer sub-field) 2022 for registering the customer.

[0049] By obtaining the sum of the respective manufacturing volumes (respective production volumes) registered in the production volume field 203 of each record, the total amount of each product of various types manufactured in the factory during the specified period is obtained. In Figure 3 the example shown, although the description of a part of the production volume is omitted, the total amount is 1500 [tons].

[0050] The equipment-related actual performance information storage unit 53 is used to store equipment-related actual performance information. The equipment-related actual performance information is data showing the total amount of each manufacturing load applied to the main equipment and the auxiliary equipment respectively during the specified period for each main equipment and auxiliary equipment, and the respective consumption amounts of the consumables accompanying the operation of the main equipment and the auxiliary equipment, that is, the consumables accompanied by carbon dioxide emissions. In addition, as can be seen from the examples described later, the consumption amount includes monetary consumption (expenses). The auxiliary equipment is equipment that indirectly participates in the manufacturing of the product through the main equipment and is used for multiple equipment (including the main equipment and the auxiliary equipment), and is appropriately determined according to the multiple equipment. In one example, the auxiliary equipment is a roll grinding equipment for grinding the rolls of a grinding rolling equipment, a boiler equipment for supplying steam to various equipment, etc.

[0051] In this embodiment, this equipment-related actual performance information is stored in the equipment-related actual performance information storage unit 53 in the form of a table. The equipment-related actual performance information table 300 for registering this equipment-related actual performance information is, for example, as Figure 4As shown, it includes: a device name field 302 for registering a device name (the name of the device) that is an identifier for determining and identifying a device (a main device and a secondary device); a device discrimination field 301 for registering whether the device with the device name registered in the device name field 302 is a main device or a secondary device; a manufacturing load field 303 for registering the total amount of the manufacturing load of the device with the device name registered in the device name field 302 during the specified period; and a consumption field 304 for registering the consumption amount of consumables of the device with the device name registered in the device name field 302, and has a record for each device (device name). The manufacturing load field 303 has sub-fields according to different units of the manufacturing load, including: a weight field (weight sub-field) 3031 for registering the total amount of the manufacturing load expressed in weight [tons] (the total amount of the products manufactured by the main device); and a time field (time sub-field) 3032 for registering the total amount of the manufacturing load expressed in usage time [hours] (the total usage time of the main device). The consumption field 304 has sub-fields according to different types of consumables, including: an energy field (energy sub-field) 3041 for registering the consumption amount of the energy consumed during the operation of the device; and a consumable field (consumable sub-field) 3042 for registering the consumption amount of the consumables used by the device. The energy field 3041 also has sub-fields according to different types of energy, including: an electric power field (electric power sub-field) 30411 for registering the electric power consumption [kWh]; an LNG field (LNG sub-field) 30412 for registering the consumption amount of liquefied natural gas (LNG) [kg]; and a steam field (steam sub-field) 30413 for registering the consumption amount of steam [kg]. The consumable field 3042 also has sub-fields according to different types of consumables, including: a chemical field (chemical sub-field) 30421 for registering the consumption amount of chemicals; and a lubricating oil field (lubricating oil sub-field) 30422 for registering the consumption amount of lubricating oil.

[0052] In addition, in the above description, the consumables are energy and consumables, but these are only examples and can be any substances suitable for the types of factories, devices, etc. In addition to these, for example, there are kerosene, refractories, maintenance operations, industrial water, etc.

[0053] The remaining emission source-related actual information storage unit 54 is used to store the remaining emission source-related actual information. The remaining emission sources refer to the remaining CO2 emission sources that emit CO2 in the factory other than the main equipment, the auxiliary equipment in the case where there is an auxiliary equipment, and the designated treatment in the case where there is a designated treatment. For example, in-factory transportation devices (such as cranes, trucks, forklifts, etc.) that transport items such as raw materials, manufactured products, and products in the factory, and shared facilities (such as offices, welfare facilities, experimental facilities, etc.) that are not directly related to the manufacture of products and can be shared, devices (such as indoor lighting devices, hot water devices, experimental devices, etc.) that are accompanied by CO2 emissions, and industrial waste treatment facilities that treat industrial waste in the factory. The designated treatment is the treatment performed on the product from after the product is manufactured until it is delivered to the delivery destination. For example, inspection treatment for inspecting the product (such as inspection treatment for checking whether the product meets the factory-out standards), packaging treatment for packaging the product, transportation treatment for transporting the product from the factory to the delivery destination, etc. The remaining emission source-related actual information is data showing the consumption amount of the consumables accompanied by the operation of the remaining emission sources within a specified period for each remaining emission source, that is, the consumption amount of the consumables accompanied by carbon dioxide emissions.

[0054] In the present embodiment, the remaining emission source-related actual information is stored in the remaining emission source-related actual information storage unit 54 in the form of a table. The remaining emission source-related actual information table 400 for registering the remaining emission source-related actual information is, for example, as Figure 5 shown, and includes: a name field 401 for registering the name of the remaining emission source, and a consumption field 402 for registering the consumption amount of the consumables of the remaining emission source whose name is registered in the name field 401, and has a record for each remaining emission source. The consumption field 402 has sub-fields according to different types of consumables, including: an electric power field (electric power sub-field) 4021 for registering the electric power consumption [kWh], a light oil field (light oil sub-field) 4022 for registering the consumption amount of light oil [kL], and an expense field (expense sub-field) 4023 for registering the expense [thousand yen]. In the present embodiment, in the industrial waste treatment facility, since the CO2 emission amount accompanied by the treatment of industrial waste is converted according to the expense, an expense field 4023 is provided.

[0055] The unit emission amount information storage unit 55 is used to store the unit emission amount information. The unit emission amount information is data representing a coefficient for converting the actual values of the above-mentioned product manufacturing actual information, equipment-related actual information, and remaining emission source-related information, etc. into CO2 emission amounts, that is, the unit CO2 emission amount (emission coefficient) per unit.

[0056] In the present embodiment, the unit emission amount information is stored in the unit emission amount information storage unit 55 in a table format. The unit emission amount information table for registering the unit emission amount information is, for example, as shown in Figure 6 A to Figure 6 C, and includes three unit emission amount information tables, namely the first to third unit emission amount information tables 500a to 500c. In addition, the unit emission amount information tables may be summarized into one table, or may be two or four or more tables, and the number of tables is arbitrary.

[0057] The first unit emission amount information table 500a is a table for registering the CO2 emission amount per unit of the raw material (the first unit CO2 emission amount per unit). In the present embodiment, since the raw material is determined according to the product manufactured from the raw material, in the first unit emission amount information table 500a, the first unit CO2 emission amount per unit is associated with the product. Therefore, the first unit emission amount information table 500a is, for example, as shown in Figure 6 A, and includes: a product field 501a for registering the product, and an emission coefficient field 502a for registering the first unit CO2 emission amount per unit corresponding to the product registered in the product field 501a, and has a record for each product. In addition, associating the first unit CO2 emission amount per unit with the product is merely an example and is not limited thereto. Of course, the first unit CO2 emission amount per unit may also be associated with the raw material (raw material name).

[0058] The second unit emission amount information table 500b is a table for registering various CO2 emission amounts per unit (unit CO2 emission amounts). In the present embodiment, for example, it is: the CO2 emission amount per unit of the consumable (consumable unit CO2 emission amount), and the CO2 emission amount per unit of the treatment of industrial waste in the industrial waste treatment facility (industrial waste treatment unit CO2 emission amount), etc. The second unit emission amount information table 500b is, for example, as shown in Figure 6 B, and includes: a name field 501b for registering the name (consumable name, industrial waste treatment, etc.), an emission coefficient field 503b for registering the unit CO2 emission amount of the name registered in the name field 501b, and a unit field 502b for registering the unit of the unit CO2 emission amount registered in the emission coefficient field 503b, and has a record for each name.

[0059] The 3rd unit emission information table 500c is a table that registers the CO2 emissions per unit of the specified process (the 3rd unit CO2 emissions per unit). In this embodiment, it is a table that registers the CO2 emissions per unit of the transportation process in the specified process (transportation process unit CO2 emissions). In this embodiment, for the transportation process, its CO2 emissions are generally determined according to factors such as the transportation distance, the total weight of the products being transported, and the transportation method. However, in this embodiment, these are determined according to the customer, and in the 3rd unit emission information table 500c, the transportation process unit CO2 emissions are associated with the customer. Therefore, the 3rd unit emission information table 500a, for example, as Figure 6 shown in C, includes: a customer field 501c that registers the customer, and an emission coefficient field 502c that registers the transportation process unit CO2 emissions corresponding to the customer registered in the customer field 501c, and has a record for each customer. Additionally, associating the transportation process unit CO2 emissions with the customer is merely an example and is not limited thereto.

[0060] The auxiliary equipment correspondence information storage unit 56 is used to store the auxiliary equipment correspondence information. As described above, an auxiliary equipment is a device that indirectly participates in the manufacturing of the product through the main equipment and is used for multiple devices (including other auxiliary equipment related to the main equipment and this auxiliary equipment). Therefore, the auxiliary equipment correspondence information is data indicating the devices that use this auxiliary equipment.

[0061] This auxiliary equipment correspondence information is stored in the auxiliary equipment correspondence information storage unit 56 in the form of a two-dimensional matrix. The auxiliary equipment correspondence information matrix 600 that registers this auxiliary equipment correspondence information, for example, as Figure 7 shown, includes: each column 601-1 to 601-11 that registers the names of the devices that share this auxiliary equipment, and each row 602-1, 602-2 that registers the names of the auxiliary equipment. In each column where the columns 601-1 to 601-11 of the devices intersect with the rows 602-1, 602- of the auxiliary equipment, when the device uses this auxiliary equipment, a flag "1" indicating this situation is registered, and when the device does not use this auxiliary equipment, it is left blank to indicate this situation. Additionally, when the device does not use this auxiliary equipment, a flag "0" indicating this situation can also be registered. In the Figure 7 example shown, three rolling processes 1, 2, and 3 share the roll grinding equipment, which is an auxiliary equipment.

[0062] Before calculating the CO2 emissions of the object products of the relevant object type during the specified period, various actual values for calculating the CO2 emissions of the object products of the relevant object type are pre-stored in the storage unit 5. The actual values can be input from the input unit 1, or can be input via the IF unit 3 from a storage medium (such as a USB memory or an SD card (registered trademark), etc.) storing the actual values, or can be input via its drive device and the IF unit 3 from a recording medium (such as a CD-R or a DVD-R, etc.) recording the actual values, or can be input via the communication network and the IF unit 3 from a management server device managing the actual values, or can also be collected and input from the main device or the sub-device via the communication network and the IF unit 3.

[0063] In the present embodiment, the CO2 emissions per unit of the main device (the second unit of CO2 emissions per unit) and the CO2 emissions per unit product of the remaining emission sources (the fourth unit of CO2 emissions per unit product) are calculated and obtained as described later, but various other unit CO2 emissions are given and pre-stored in the unit emissions information storage unit 55. In addition, the CO2 emissions per unit of the main device include the CO2 emissions of the sub-device as described later.

[0064] Figure 8 It is a diagram for explaining an example of each calculation method for calculating the total amount of process CO2 emissions in the process performed by the main device and the total amount of sub-device CO2 emissions of the sub-device. Figure 9 It is a diagram for explaining an example of the calculation method for calculating the CO2 emission allocation amount of the main device using the sub-device. Figure 10 It is a diagram for explaining an example of the calculation method for calculating the second unit of CO2 emissions per unit of the main device. Figure 11 It is a diagram for explaining an example of the calculation method for calculating the fourth unit of CO2 emissions per unit product of the remaining emission sources. Figure 12 It is a diagram showing an example of the output of each calculation result. Figure 13 It is a diagram showing another example of the output of each calculation result.

[0065] Return Figure 1, the control processing unit 4 is a circuit that controls each of the components 1 to 3, 5 of the carbon dioxide emissions calculation device S according to the functions of these components, and calculates the CO2 emissions of the target product of the target type. The control processing unit 4 includes, for example, a CPU (Central Processing Unit) and its peripheral circuits. By executing the control processing program, the control unit 41, the raw material emissions calculation unit 42, the main equipment unit emissions calculation unit 43, the process emissions calculation unit 44, the emission allocation amount calculation unit 45, the incidental processing emissions calculation unit 46, the first remaining emissions calculation unit 47, the second remaining emissions calculation unit 48, and the target product emissions calculation unit 49 are functionally formed in the control processing unit 4.

[0066] The control unit 41 is used to control each of the components 1 to 3, 5 of the carbon dioxide emissions calculation device according to the functions of these components respectively, so as to perform overall control of the carbon dioxide emissions calculation device.

[0067] The raw material emissions calculation unit 42 calculates the total amount of raw material CO2 emissions related to the raw materials in the manufacture of the target product of the target type based on the first unit CO2 emissions per unit of the raw materials used in manufacturing the target product of the target type given, and the total amount of the raw materials used in manufacturing the target product of the target type during the specified period.

[0068] For example, in the case of obtaining the total raw material CO2 emissions related to the raw materials for the target product of the product type of the product No. "P001", in the present embodiment, as described above, since the total amount of the raw materials used for the target product of the target product type manufactured during the specified period is registered in the manufacturing process information table 100, the raw material emissions calculation unit 42 first extracts (reads) the actual value "26" [tons] registered in the weight field 103 of the first process from the manufacturing process information table 100a of the product No. "P001" stored in the manufacturing process information storage unit 51 as the total amount of the raw materials. Next, in the present embodiment, as described above, since the first unit CO2 emissions per unit of the raw material are registered in the first unit emissions information table 500a in association with the variety, the raw material emissions calculation unit 42 searches and selects the record registered with "P001" in the product No. field 201 from the product manufacturing actual information table 200 stored in the product manufacturing actual information storage unit 52, and extracts the variety "H1" registered in the variety field 2021 of the selected record. Next, the raw material emissions calculation unit 42 searches and selects the record registered with "H1" in the variety field 501a from the first unit emissions information table 500a stored in the unit emissions information storage unit 55, and extracts the first unit CO2 emissions per unit of the raw material "1.2" [tCO2 / ton] registered in the emission coefficient field 502a of the selected record. Then, the raw material emissions calculation unit 42 multiplies the first unit CO2 emissions per unit of the raw material "1.2" [tCO2 / ton] by the total amount of the raw materials "26" [tons] used for the target product of the target product type manufactured during the specified period, thereby obtaining the total raw material CO2 emissions "31.2" [tCO2] related to the raw materials in the manufacture of the target product of the target product type during the specified period.

[0069] The emission allocation calculation unit 45 allocates the total amount of the CO2 emissions of the auxiliary equipment during the specified period to each of the multiple devices that use the auxiliary equipment at a specified ratio for the auxiliary equipment that indirectly participates in the manufacture of the product through the main equipment and is used for multiple devices, so as to calculate the CO2 emission allocation amount of the equipment using the auxiliary equipment for each of the multiple devices that use the auxiliary equipment. In the present embodiment, the emission allocation calculation unit 45 calculates the total amount of the CO2 emissions per unit of the auxiliary equipment during the specified period based on the total amount of the consumables accompanying the operation of the auxiliary equipment during the specified period, that is, the consumables accompanied by carbon dioxide emissions, and the CO2 emissions per unit of the consumables (the CO2 emissions per unit of the fifth unit). The specified ratio can be appropriately set and stored in the storage unit 5 in advance, for example, but in the present embodiment, as will be described later, it is calculated based on the actual values. The specified ratio is, for example, the usage ratio of the products manufactured using the auxiliary equipment for each of the multiple devices that use the auxiliary equipment. Alternatively, the specified ratio is, for example, the ratio of the production amounts of the respective products manufactured separately in the multiple devices for each of the multiple devices that use the auxiliary equipment.

[0070] In Figure 4 In the example shown, the auxiliary equipment is a roll grinding equipment and a boiler equipment, and thus these will be described in more detail.

[0071] In the case of the boiler equipment, the emission allocation calculation unit 45 first extracts the consumption amount of the consumables related to the operation of the boiler equipment from the equipment-related actual information stored in the equipment-related actual information storage unit 53. In Figure 4 In the example shown, the emission allocation calculation unit 45 first searches and selects the record in the equipment-related actual information table 300 stored in the equipment-related actual information storage unit 53 where the equipment name "boiler" is registered in the equipment name field 302, and extracts the consumption amount of the consumables registered in the consumption field 304 of the selected record. For example, from the record of the "boiler", "2000" [kWh] is extracted as the power consumption amount, and "2000" [kg] is extracted as the LNG consumption amount. Next, the emission allocation calculation unit 45 extracts the CO2 emissions per unit of the fifth unit of the consumables related to the operation of the boiler equipment from the unit emission information stored in the unit emission information storage unit 55. In Figure 6In the example shown in B, the emission allocation calculation unit 45 searches and selects, from the second unit emission information table 500b stored in the unit emission information storage unit 55, each record in which "electricity" and "LNG" are respectively registered in the name field 501b, and extracts the respective fifth unit CO2 emissions per unit of electricity and LNG and their respective units registered in the emission coefficient field 503b and the unit field 502b in each of these selected records. The fifth unit CO2 emission of electricity (electricity unit CO2 emission) "0.0005" [tCO2 / kWh] is extracted, and the fifth unit CO2 emission of LNG (LNG unit CO2 emission) "0.004" [tCO2 / kg] is extracted. Next, as Figure 8 shown, the emission allocation calculation unit 45 multiplies the electricity consumption "2000" [kWh] by its electricity unit CO2 emission "0.0005" [tCO2 / kWh] to obtain the total amount of CO2 emissions related to electricity "1" [tCO2] during the specified period, and multiplies the LNG consumption "2000" [kg] by its LNG unit CO2 emission "0.004" [tCO2 / kg] to obtain the total amount of CO2 emissions related to LNG "8" [tCO2] during the specified period, and calculates their sum to obtain the total amount of auxiliary equipment CO2 emissions (boiler equipment CO2 emissions) related to the boiler equipment of the auxiliary equipment "10" [tCO2] during the specified period. The sum of the total amount of CO2 emissions related to electricity "1" [tCO2] and the total amount of CO2 emissions related to LNG "8" [tCO2] is "9" [tCO2], but for the convenience of the following description, the total amount of CO2 emissions related to the consumables (not shown in the figure) "1" [tCO2] is added, and the total amount of boiler equipment CO2 emissions is set to "10" [tCO2].

[0072] In the case where the auxiliary equipment is a boiler equipment, the specified ratio uses the usage ratio (usage rate) of the manufactured products using the auxiliary equipment for each of the multiple equipment using the auxiliary equipment. More specifically, the emission allocation calculation unit 45 first extracts, from the auxiliary equipment correspondence information stored in the auxiliary equipment correspondence information storage unit 56 ( Figure 7 the auxiliary equipment correspondence information matrix 600 in the example shown), the equipment that uses the steam generated by the boiler equipment. In Figure 7In the example shown, the main devices of the equipment names "Casting 1", "Casting 2", "Rolling 1", "Rolling 2", "Rolling 3", "Heat Treatment", "Plating", "Cutting 2" where the flag "1" is registered, and the auxiliary device of the equipment name "Roller Grinding" are extracted. Next, the emission allocation calculation unit 45 extracts the steam usage amounts of the equipment that uses the steam produced by the boiler equipment from the equipment-related actual performance information stored in the equipment-related actual performance information storage unit 53. In Figure 4 In the example shown, the emission allocation calculation unit 45 searches and selects each record in the equipment-related actual performance information table 300 stored in the equipment-related actual performance information storage unit 53 where "Casting 1", "Casting 2", "Rolling 1", "Rolling 2", "Rolling 3", "Heat Treatment", "Plating", "Cutting 2", and "Roller Grinding" are respectively registered in the equipment name field 302, and extracts the respective usage amounts of the steam registered in the steam field 30413 in each of these records: "0" [kg], "0" [kg], "400" [kg], "1200" [kg], "800" [kg], "400" [kg], "800" [kg], "0" [kg], "0" [kg], and "400" [kg]. Then, as Figure 9 shown in A, the emission allocation calculation unit 45 calculates the steam usage ratio (steam usage rate) of the boiler equipment based on the respective usage amounts of the extracted steam, and multiplies the calculated usage ratio (steam usage rate) by the total amount of CO2 emissions from the boiler equipment, "10" [tCO2], to obtain the respective CO2 emission allocations for each of the multiple equipment that uses the boiler equipment. For example, for the main device of the equipment name "Rolling 1", the steam usage ratio 0.1 is multiplied by the total amount of CO2 emissions from the boiler equipment, "10" [tCO2], to obtain 1 [tCO2] as its CO2 emission allocation. In addition, for example, for the auxiliary device of the equipment name "Roller Grinding", the steam usage ratio 0.1 is multiplied by the total amount of CO2 emissions from the boiler equipment, "10" [tCO2], to obtain 1 [tCO2] as its CO3 emission allocation.

[0073] In the case of the roller grinding equipment, the emission allocation calculation unit 45 first extracts the consumption amounts of the consumables related to the operation of the roller grinding equipment from the equipment-related actual performance information stored in the equipment-related actual performance information storage unit 53. In Figure 4In the example shown, the emission allocation calculation unit 45 first searches and selects, from the equipment-related actual performance information table 300 stored in the equipment-related actual performance information storage unit 53, each record in which the equipment name "roll grinding" is registered in the equipment name field 302, and extracts the consumption amounts of the consumables registered in the consumption field 304 in each of the selected records. For example, from the record of "roll grinding", "10000" [kWh] is extracted as the power consumption amount, "400" [kg] is extracted as the steam consumption amount, and 5 [kL] is extracted as the lubricating oil consumption amount. Next, the emission allocation calculation unit 45 extracts the per-unit fifth-unit CO2 emissions of the consumables related to the operation of the roll grinding equipment from the per-unit emission information stored in the per-unit emission information storage unit 55. As described above, since the emission allocation calculation unit 45 has already obtained the total amount of CO2 emissions related to steam as "1" [tCO2], the per-unit fifth-unit CO2 emissions of "electricity" and the per-unit fifth-unit CO2 emissions of "lubricating oil" are extracted. In Figure 6 In the example shown in B, the emission allocation calculation unit 45 searches and selects, from the second-unit emission information table 500b stored in the per-unit emission information storage unit 55, each record in which "electricity" and "lubricating oil" are respectively registered in the name field 501b, and extracts the per-unit fifth-unit CO2 emissions of electricity and lubricating oil and their respective units registered in the emission coefficient field 503b and the unit field 502b in each of the selected records. The per-unit fifth-unit CO2 emissions of electricity (electricity per-unit CO2 emissions) "0.0005" [tCO2 / kWh] are extracted, and the per-unit fifth-unit CO2 emissions of lubricating oil (lubricating oil per-unit CO2 emissions) "0.8" [tCO2 / kL] are extracted. Next, as Figure 8 shown, the emission allocation calculation unit 45 multiplies the power consumption amount "10000" [kWh] by its electricity per-unit CO2 emissions "0.0005" [tCO2 / kWh] to obtain the total amount of CO2 emissions related to electricity during the specified period as "5" [tCO2], and multiplies the lubricating oil consumption amount "5" [kL] by its lubricating oil per-unit CO2 emissions "0.8" [tCO2 / kL] to obtain the total amount of CO2 emissions related to lubricating oil during the specified period as "4" [tCO2]. Moreover, the sum of them is obtained, and the total amount of CO2 emissions related to steam, which is "1" [tCO2] as described above, is added to this sum to obtain the total amount of sub-equipment CO2 emissions (roll grinding equipment CO2 emissions) of the roll grinding equipment, which is a sub-equipment, during the specified period as "10" [tCO2].

[0074] In the case where the sub-equipment is a roll grinding equipment, the specified ratio is the ratio of the production amounts of the respective products manufactured by the respective multiple equipment of the sub-equipment. InFigure 9 In the example shown in FIG. B, the production amount ratio is expressed by weight, but it is not limited thereto. For example, it can be appropriately set according to the type of the manufactured product, etc., and can be expressed by the volume of the manufactured product after processing, etc. More specifically, the emission allocation amount calculation unit 45 first extracts the equipment using the roll grinding equipment from the auxiliary equipment correspondence information stored in the auxiliary equipment correspondence information storage unit 56 ( Figure 7 the auxiliary equipment correspondence information matrix 600 in the example shown). In Figure 7 the example shown, the main equipment with the equipment name "rolling 1" registered with the flag "1", the main equipment with the equipment name "rolling 2", and the main equipment with the equipment name "rolling 3" are extracted. Next, the emission allocation amount calculation unit 45 extracts the production amount of the manufactured product of the equipment using the roll grinding equipment from the equipment-related actual performance information stored in the equipment-related actual performance information storage unit 53. In Figure 4 the example shown, the emission allocation amount calculation unit 45 searches and selects each record registered with "rolling 1", "rolling 2", and "rolling 3" in the equipment name field 302 from the equipment-related actual performance information table 300 stored in the equipment-related actual performance information storage unit 53, and extracts the respective weights "600" [tons], "2000" [tons], and "1400" [tons] registered in the weight field 3031 of these respective records. Then, as Figure 9 shown in FIG. B, the emission allocation amount calculation unit 45 calculates the production amount ratio of the manufactured product based on these extracted weights, calculates the weight ratio here, and multiplies the calculated production amount ratio of the manufactured product, that is, the weight ratio, by the total amount of CO2 emissions of the roll grinding equipment "10" [tCO2], so as to calculate, for each of the plurality of equipment using the roll grinding equipment, the respective CO2 emission allocation amounts of the equipment using the roll grinding equipment. For example, for the main equipment with the equipment name "rolling 1", the weight ratio 0.15 is multiplied by the total amount of CO2 emissions of the roll grinding equipment "10" [tCO2], and 1.5 [tCO2] is calculated as its CO2 emission allocation amount.

[0075] In the present embodiment, among the total amount of CO2 emissions of the boiler equipment "10" [tCO2], the total amount of CO2 emissions "1" [tCO2] related to the steam used by the roll grinding equipment is allocated to the main equipment through the respective CO2 emission allocation amounts related to the equipment using the roll grinding equipment, as will be described later.

[0076] The main equipment unit emissions calculation unit 43 calculates the second unit CO2 emissions per unit of each main equipment among the multiple main equipments respectively corresponding to the multiple processes for manufacturing the object products of the object type, based on the total amount of the manufacturing load applied to the main equipment corresponding to the process and used for performing the process during the manufacturing within the specified period, and the total amount of the CO2 emissions of the main equipment related to the total amount of the manufacturing load. In the present embodiment, the main equipment unit emissions calculation unit 43 calculates the total amount of the CO2 emissions of each main equipment among the multiple main equipments respectively corresponding to the multiple processes for manufacturing the object products of the object type, based on the total amount of the consumables accompanied by the operation of the main equipment during the specified period, that is, the consumables accompanied by carbon dioxide emissions, and the fifth unit CO2 emissions per unit of the consumables.

[0077] For example, the total amount of the manufacturing load is represented by the total amount of the products manufactured by the main equipment. The main equipment unit emissions calculation unit 43 calculates the second unit CO2 emissions per unit of each main equipment among the multiple main equipments respectively corresponding to the multiple processes for manufacturing the object products of the object type, based on the total amount of the products manufactured by the main equipment during the specified period and the total amount of the CO2 emissions of the main equipment related to the total amount of the products manufactured. Or, for example, the total amount of the manufacturing load is represented by the total usage time of the main equipment. The main equipment unit emissions calculation unit 43 calculates the second unit CO2 emissions per unit of each main equipment among the multiple main equipments respectively corresponding to the multiple processes for manufacturing the object products of the object type, based on the total usage time spent by the main equipment during the manufacturing within the specified period and the total amount of the CO2 emissions of the main equipment related to the usage of the total usage time.

[0078] Moreover, in the present embodiment, when the main equipment unit emissions calculation unit 43 calculates the second unit CO2 emissions per unit of the main equipment, in the case where the auxiliary equipment is provided for the main equipment, by adding the CO2 emission allocation amount of the equipment corresponding to the main equipment calculated by the emission allocation amount calculation unit 45 to the total amount of the CO2 emissions of the main equipment related to the total amount of the manufacturing load, the new total amount of the CO2 emissions of the main equipment related to the total amount of the manufacturing load is obtained, and based on the obtained new total amount of the CO2 emissions of the main equipment related to the total amount of the manufacturing load, the second unit CO2 emissions per unit of the main equipment are calculated.

[0079] For example, in the case where the object product is the product of the object type of the product No. "P001", in order to obtain a plurality of processes for manufacturing the object product of the object type, the main equipment unit emission calculation unit 43 first extracts all the processes for manufacturing the product of the product No. "P001" from the manufacturing process information table 100a related to the product of the product No. "P001" stored in the manufacturing process information storage unit 51. In Figure 2 the example shown in Figure 2 A, the first process performed by the main equipment with the equipment name "Casting 1", the second process performed by the main equipment with the equipment name "Rolling 1", the third process performed by the main equipment with the equipment name "Rolling 2", the fourth process performed by the main equipment with the equipment name "Heat Treatment", and the fifth process performed by the main equipment with the equipment name "Cutting 1" are extracted. Next, the main equipment unit emission calculation unit 43 extracts the consumption amounts of consumables related to the operation of each main equipment corresponding to each of the first to fifth processes from the equipment-related actual performance information stored in the equipment-related actual performance information storage unit 53. In Figure 4 the example shown in Figure 6 A and Figure 8As shown, the main equipment unit emissions calculation unit 43 multiplies the LNG consumption of "80,000" [kg] by its LNG unit CO2 emissions of "0.004" [tCO2 / kg] to obtain the total amount of CO2 emissions related to LNG during the specified period of "320" [tons], multiplies the chemical consumption of "6,000" [thousand yen] by the chemical unit CO2 emissions of "0.01" [tCO2 / thousand yen] to obtain the total amount of CO2 emissions related to chemicals during the specified period of "60" [tCO2], and calculates their sum to obtain the total amount of CO2 emissions of the main equipment with the equipment name "Melting 1" related to the manufacturing of the total amount of the manufactured products manufactured by this main equipment during the specified period of "420" [tCO2]. Similarly, for each main equipment with the equipment names "Rolling 1", "Rolling 2", "Heat Treatment", and "Cutting 1", the total amount of CO2 emissions of the main equipment related to the manufacturing of the total amount of the manufactured products manufactured by this main equipment during the specified period is obtained as "48" [tCO2], "60" [tCO2], "48" [tCO2], and "8" [tCO2], respectively.

[0080] Here, in the case where a sub-equipment is provided for the main equipment, such as the main equipment with the equipment name "Rolling 1", the main equipment unit emissions calculation unit 43 adds the CO2 emission allocation amount related to the equipment corresponding to the main equipment obtained by the emission allocation amount calculation unit 45 as described above to the total amount of CO2 emissions of the main equipment related to the total amount of the manufacturing load, so as to obtain a new total amount of CO2 emissions of the main equipment related to the total amount of the manufacturing load. For example, in the case of the main equipment with the equipment name "Rolling 1", as Figure 8As shown, the main equipment unit emissions calculation unit 43 multiplies the power consumption of "50,000" [kWh] by its power unit CO2 emissions of "0.0005" [tCO2 / kWh] to obtain the total amount of CO2 emissions related to power of "25" [tCO2] during the specified period, multiplies the lubricating oil consumption of "5" [kL] by its lubricating oil unit CO2 emissions of "0.8" [tCO2 / kL] to obtain the total amount of CO2 emissions related to lubricating oil of "4" [tCO2] during the specified period, and calculates their sum, thereby obtaining the total amount of CO2 emissions of the main equipment with the equipment name "Rolling 1" related to the total manufacturing load imposed on the main equipment with the equipment name "Rolling 1" during the specified period of "45.5" [tCO2]. The sum of the total amount of CO2 emissions related to power of "25" [tCO2] and the total amount of CO2 emissions related to lubricating oil of "4" [tCO2] is "29" [tCO2], but for the sake of explanation, adding the total amount of CO2 emissions related to consumables (not shown in the figure) of "16.5" [tCO2], the total amount of CO2 emissions of the main equipment with the equipment name "Rolling 1" is set to "45.5" [tCO2]. And further as Figure 10 shown, the main equipment unit emissions calculation unit 43 adds the CO2 emission allocation amount of the equipment corresponding to the main equipment obtained by the emission allocation amount calculation unit 45, that is, the CO2 emission allocation amount of the boiler equipment to the main equipment with the equipment name "Rolling 1" of "1" [tCO2] and the CO2 emission allocation amount of the roll grinding equipment to the main equipment with the equipment name "Rolling 1" of "1.5" [tCO2] to the total amount of CO2 emissions of the main equipment with the equipment name "Rolling 1" of "45.5" [tCO2], thereby obtaining the new total amount of CO2 emissions of the main equipment with the equipment name "Rolling 1" of "48" [tCO2].

[0081] Next, the main equipment unit emissions calculation unit 43 extracts, for each main equipment corresponding to each of the first to fifth processes respectively, the total manufacturing load imposed on the main equipment during the manufacturing in the specified period from the equipment-related actual performance information stored in the equipment-related actual performance information storage unit 53. In Figure 2 A and Figure 4In the example shown, the main equipment unit emissions calculation unit 43 searches and selects from the equipment-related actual performance information table 300 stored in the equipment-related actual performance information storage unit 53 the records in which the equipment names "casting 1", "rolling 1", "rolling 2", "heat treatment", and "cutting 1" of the main equipment used in the first to fifth processes are respectively registered in the equipment name field 302, and extracts the total amounts of the respective manufacturing loads registered in the manufacturing load field 303 in these selected records. For example, "1200" [tons] is extracted as the total amount of the manufactured product from the record of the equipment name "casting 1". In addition, for example, "600" [tons] is extracted as the total amount of the manufactured product from the record of the equipment name "rolling 1", and "120" [hrs] is extracted as the total usage time.

[0082] Then, the main equipment unit emissions calculation unit 43 calculates the second unit CO2 emissions per unit of the main equipment for each of the main equipment corresponding to the first to fifth processes respectively, based on the total amount of the manufacturing load applied to the main equipment during the manufacturing in the specified period obtained as described above and the total amount of the CO2 emissions of the main equipment related to the total amount of the manufacturing load obtained as described above. For example, as Figure 10As shown, the main equipment unit emissions calculation unit 43 divides the total amount of CO2 emissions “420” [tCO2] of the main equipment with the equipment name “Casting 1” related to the total manufacturing load by the total amount of the manufacturing load applied to the main equipment with the equipment name “Casting 1” during manufacturing in the specified period, that is, the total amount of manufactured products “1200” [tons], thereby obtaining the second unit CO2 emissions per unit of the main equipment with the equipment name “Casting 1” (Casting 1 unit CO2 emissions) “0.35” [tCO2 / ton] (420 / 1200 = 0.35). In addition, for example, the main equipment unit emissions calculation unit 43 divides the total amount of CO2 emissions “48” [tCO2] of the main equipment with the equipment name “Rolling 1” related to the total manufacturing load by the total amount of the manufacturing load applied to the main equipment with the equipment name “Rolling 1” during manufacturing in the specified period, that is, the total amount of manufactured products “600” [tons], and the total usage time “120” [hrs] respectively, thereby obtaining the second unit CO2 emissions per unit of the main equipment with the equipment name “Rolling 1” (Rolling 1 unit CO2 emissions) “0.08” [tCO2 / ton] and “0.4” [tCO2 / hrs] (48 / 600 = 0.08, 48 / 120 = 0.4). Similarly, for the main equipment with the equipment names “Rolling 2”, “Heat Treatment” and “Cutting 1”, the respective second unit CO2 emissions “0.03” [tCO2 / ton] and “0.3” [tCO2 / hrs], “0.03” [tCO2 / ton] and “0.01” [tCO2 / ton] are obtained.

[0083] In addition, as described above, the total amount of manufactured products “600” [tons] and the total usage time “120” [hrs] can both be extracted as the total manufacturing load of the main equipment with the equipment name “Rolling 1”, and the second unit CO2 emissions for each unit [tCO2 / ton], [tCO2 / hrs] can be obtained. However, it is also possible to only extract the one used as the second unit CO2 emissions per unit of the main equipment with the equipment name “Rolling 1” and obtain the second unit CO2 emissions for that unit. For example, the total usage time “120” [hrs] can be extracted only as the total manufacturing load of the main equipment with the equipment name “Rolling 1”, and only the Casting 1 unit CO2 emissions “0.4” [tCO2 / hrs] of the main equipment with the equipment name “Rolling 1” can be obtained. Which of the second unit CO2 emissions using each unit [tCO2 / ton] and [tCO2 / hrs] to use is appropriately set in advance by the user (operator). For example, it is input from the input unit 1 to the carbon dioxide emissions calculation device S and set, and the main equipment unit emissions calculation unit 43 obtains the second unit CO2 emissions corresponding to the set unit.

[0084] In addition, for the sake of illustration, in Figures 8 to 10 there are also recorded various data other than the main equipment of "casting 1", "rolling 1", "rolling 2", "heat treatment", and "cutting 1" in terms of equipment names, and the auxiliary equipment of "roll grinding" and "boiler" in terms of equipment names.

[0085] Returning to Figure 1 , for each main equipment among the multiple main equipment corresponding to the multiple processes for manufacturing the object product of the object type, the process emission calculation unit 44 calculates the process CO2 emission in the process performed by the main equipment for manufacturing the object product of the object type based on the second unit CO2 emission per unit of the main equipment obtained by the main equipment unit emission calculation unit 43 and the total amount of the manufacturing load applied to the main equipment for manufacturing the object product of the object type during the manufacturing in the specified period. When the total amount of the manufactured product is used to represent the total amount of the manufacturing load, for each main equipment among the multiple main equipment corresponding to the multiple processes for manufacturing the object product of the object type, the process emission calculation unit 44 calculates the process CO2 emission in the process performed by the main equipment for manufacturing the object product of the object type based on the second unit CO2 emission per unit of the main equipment obtained by the main equipment unit emission calculation unit and the total amount of the manufactured product of the object product of the object type manufactured by the main equipment during the specified period. When the total usage time of the main equipment is used to represent the total amount of the manufacturing load, for each main equipment among the multiple main equipment corresponding to the multiple processes for manufacturing the object product of the object type, the process emission calculation unit 44 calculates the process CO2 emission in the process performed by the main equipment for manufacturing the object product of the object type based on the second unit CO2 emission per unit of the main equipment obtained by the main equipment unit emission calculation unit and the total usage time of the main equipment applied to the manufacturing of the object product of the object type during the manufacturing in the specified period.

[0086] For example, in the case where the object product is of the object type of the product No. "P001", in the present embodiment, as described above, since the total amount of the manufacturing load of the main equipment applied to the manufacturing of the object product of the object type during the specified period is registered in the manufacturing process information table 100, the process emission calculation unit 44 first extracts, for each main equipment corresponding to each of the first to fifth processes, the total amount of the manufacturing load of the main equipment applied to the manufacturing of the object product of the object type during the specified period from the manufacturing process information table 100a of the product No. "P001" stored in the manufacturing process information storage unit 51. In this example, for each main equipment with the equipment names "Casting 1", "Rolling 1", "Rolling 2", "Heat Treatment", and "Cutting 1", the total amounts of "26" [tons], "2" [hrs], "3" [hrs], "22" [tons], and "20" [tons] are respectively extracted as the total amounts of the manufacturing load.

[0087] Next, the process emission calculation unit 44 multiplies, for each main equipment corresponding to each of the first to fifth processes, the second unit CO2 emission per unit of the main equipment obtained by the main equipment unit emission calculation unit 43 as described above by the total amount of the manufacturing load of the main equipment applied to the manufacturing of the object product of the object type during the specified period, thereby obtaining the process CO2 emission in the process performed by the main equipment for manufacturing the object product of the object type. In this example, for the product No. "P001", as the process CO2 emission in the process performed by the main equipment with the equipment name "Casting 1", "9.1" [tCO2] (="0.35" [tCO2 / ton] × "26" [tons]) is obtained, as the process CO2 emission in the process performed by the main equipment with the equipment name "Rolling 1", "0.8" [tCO2] (="0.4" [tCO2 / hrs] × "2" [hrs]) is obtained, as the process CO2 emission in the process performed by the main equipment with the equipment name "Rolling 2", "0.9" [tCO2] (="0.3" [tCO2 / hrs] × "3" [hrs])) is obtained, as the process CO2 emission in the process performed by the main equipment with the equipment name "Heat Treatment", "0.66" [tCO2] (="0.03" [tCO2 / ton] × "22" [tons]) is obtained, and as the process CO2 emission in the process performed by the main equipment with the equipment name "Cutting 1", "0.2" [tCO2] (="0.01" [tCO2 / ton] × "20" [tons]) is obtained.

[0088] The incidental processing emissions calculation unit 46 calculates the total amount of incidental processing CO2 emissions in the specified processing performed on the object products of the object type based on the given third unit CO2 emissions per unit in the specified processing performed on the product from after the product is manufactured until it is delivered to the delivery destination, and the total amount of the object products of the object type manufactured in the factory during the specified period. The incidental processing emissions calculation unit 46 calculates the CO2 emissions in the specified processing performed on the object products of the object type during the specified period.

[0089] As described above, the specified processing is, for example, inspection processing, packaging processing, transportation processing, etc. Here, as an example, the transportation processing in the case where the product of product No. “P001” is the object product of the object type will be described in more detail. In the present embodiment, the third unit CO2 emissions per unit (transportation processing unit CO2 emissions) in the transportation processing are registered in the third unit emissions information table 500c stored in the unit emissions information storage unit 55 in association with the customer. Therefore, the incidental processing emissions calculation unit 46 searches and selects the record in which “P001” is registered in the product No. field 201 from the product manufacturing performance information table 200 stored in the product manufacturing performance information storage unit 52, and extracts the customer “C1” and the production volume “20” [tons] registered in the customer field 2022 and the production volume field 203, respectively, of the selected record. Next, the incidental processing emissions calculation unit 46 searches and selects the record in which “C1” is registered in the customer field 501c from the third unit emissions information table 500c stored in the unit emissions information storage unit 55, and extracts the transportation processing unit CO2 emissions “0.1” [tCO2 / ton] registered in the emission coefficient field 502c of the selected record. Then, the incidental processing emissions calculation unit 46 uses the extracted production volume “20” [tons] as the transportation volume, and multiplies the extracted transportation processing unit CO2 emissions “0.1” [tCO2 / ton] by the transportation volume (production volume) “20” [tons], thereby calculating the total amount of incidental processing CO2 emissions in the transportation processing performed on the product of product No. “P001” as “2” [tCO2] (=“0.1” [tCO2 / ton] × “20” [tons]).

[0090] The first remaining emissions calculation unit 47 calculates the fourth unit of CO2 emissions per unit of product of the remaining emission sources based on the total amount of the remaining CO2 emissions of the remaining emission sources during the specified period and the total amount of products manufactured in the factory during the specified period. The first remaining emissions calculation unit 47 calculates the total amount of the remaining CO2 emissions of the remaining emission sources based on the total amount of the consumables accompanied by the operation of the remaining emission sources during the specified period, that is, the consumables accompanied by carbon dioxide emissions, and the fifth unit of CO2 emissions per unit of the consumables.

[0091] The second remaining emissions calculation unit 48 calculates the total amount of the second remaining CO2 emissions of the remaining emission sources in the manufacture of the target products of the target type based on the fourth unit of CO2 emissions per unit of product of the remaining emission sources calculated by the first remaining emissions calculation unit 47 and the total amount of the target products of the target type manufactured during the specified period.

[0092] As described above, the remaining emission sources are, for example, in-factory transportation devices, devices accompanied by CO2 emissions in shared facilities, and industrial waste treatment facilities. Since the remaining emission sources have no direct association with specific products, the CO2 emissions related to the remaining emission sources cannot be directly allocated to specific products. Therefore, in the present embodiment, it is considered that the CO2 emissions related to the remaining emission sources are related to all products manufactured in the factory during the specified period. The first remaining emissions calculation unit 47 calculates the CO2 emissions per unit of product (the fourth unit of CO2 emissions per unit of product), and the second remaining emissions calculation unit 48 uses the CO2 emissions per unit of product to calculate the CO2 emissions allocated to the target products of the target type.

[0093] For example, in the present embodiment, the consumption amounts of the consumables in the remaining emission sources are stored in the remaining emission source-related performance information storage unit 54. Therefore, the first remaining emissions calculation unit 47 extracts the consumption amounts of the consumables from the remaining emission source-related performance information stored in the remaining emission source-related performance information storage unit 54 for each of all the remaining emission sources. In Figure 5 the example shown, the remaining emission sources are the remaining emission source with the name "in-factory transportation", the remaining emission source with the name "shared facilities", and the remaining emission source of "industrial waste treatment". The first remaining emissions calculation unit 47 extracts the consumption amounts of the respective consumables registered in the consumption field 402 of each record from the remaining emission source-related performance information table 400 stored in the remaining emission source-related performance information storage unit 54. As Figure 11As shown, for the remaining emission sources with the name "In-plant transportation", the electricity consumption of "3000" [kWh] and the light oil consumption of "10" [kL] are extracted. For the remaining emission sources with the name "Common facilities", the electricity consumption of "1000" [kWh] is extracted. For the remaining emission sources with the name "Industrial waste treatment", the light oil consumption of "1" [kL] and the cost consumption of "5000" [thousand yen] are extracted. Next, the first remaining emission calculation unit 47 extracts the fifth unit CO2 emission per unit of the consumables related to the operation of the remaining emission sources from the second unit emission information stored in the unit emission information storage unit 55. In Figure 6 In the example shown in B, the electricity unit CO2 emission of "0.0005" [tCO2 / kWh] is extracted, the fifth unit CO2 emission of light oil (light oil unit CO2 emission) of "3" [tCO2 / kg] is extracted, and the fifth unit CO2 emission of the cost spent on industrial waste treatment (industrial waste treatment cost unit CO2 emission) of "0.008" [tCO2 / thousand yen] is extracted. Next, as Figure 11 shown, the main equipment unit emission calculation unit 43 multiplies the electricity unit CO2 emission of "0.0005" [tCO2 / kWh] by the electricity consumption of "3000" [kWh] for the remaining emission sources with the name "In-plant transportation" to obtain its CO2 emission of "1.5" [tCO2], and multiplies the light oil unit CO2 emission of "3" [tCO2 / kL] by the light oil consumption of "10" [kL] to obtain its CO2 emission of "30" [tCO2]; for the remaining emission sources with the name "Common facilities", multiplies the electricity unit CO2 emission of "0.0005" [tCO2 / kWh] by the electricity consumption of "1000" [kWh] to obtain its CO2 emission of "0.5" [tCO2]; for the remaining emission sources with the name "Industrial waste treatment", multiplies the light oil unit CO2 emission of "3" [tCO2 / kL] by the light oil consumption of "1" [kL] to obtain its CO2 emission of "3" [tCO2], and multiplies the industrial waste treatment cost unit CO2 emission of "0.008" [tCO2 / thousand yen] by the consumption of the cost spent on industrial waste treatment of "5000" [thousand yen] to obtain its CO2 emission of "40" [tCO2], and by calculating their sum, the total amount of the remaining CO2 emissions related to the remaining emission sources during the specified period is obtained as "75" (=1.5 + 30 + 0.5 + 3 + 40) [tCO2]. Then, the main equipment unit emission calculation unit 43 calculates the total amount of the products manufactured in the factory during the specified period based on the product manufacturing performance information stored in the product manufacturing performance information storage unit 52. In Figure 3In the example shown, the main equipment unit emissions calculation unit 43 calculates the total amount of products manufactured at the factory during the specified period by obtaining the sum of the production quantities registered in each record of the production quantity field 203 of the product manufacturing performance information table 200 stored in the product manufacturing performance information storage unit 52. In this example, as described above, "1500" [tons] is obtained. Then, the main equipment unit emissions calculation unit 43 divides the total amount of the remaining CO2 emissions of the remaining emission sources during the specified period, which is "75" [tCO2], obtained as described above, by the total amount of products manufactured at the factory during the specified period, which is "1500" [tons], obtained as described above, to calculate the fourth unit CO2 emissions per unit product of the remaining emission sources, which is "0.05" [tCO2 / ton].

[0094] Using the fourth unit CO2 emissions per unit product, which is "0.05" [tCO2 / ton], obtained in this way, for example, when calculating the CO2 emissions allocated to a target product of the target type of product No. "P001", the second remaining emissions calculation unit 48 searches and selects the record in which "P001" is registered in the product No. field 201 from the product manufacturing performance information table 200 stored in the product manufacturing performance information storage unit 52, extracts the production quantity, which is "20" [tons], registered in the production quantity field 203 of the selected record, and multiplies the fourth unit CO2 emissions per unit product of the remaining emission sources, which is "0.05" [tCO2 / ton], obtained by the first remaining emissions calculation unit 47, by the total amount (production quantity) of the product of product No. "P001" during the specified period, which is "20" [tons], to calculate the total amount of the second remaining CO2 emissions of the remaining emission sources during the manufacturing of the product of product No. "P001", which is "1" [tCO2].

[0095] The target product emission calculation unit 49 obtains the sum of the total CO2 emissions of each process in the processes performed by the main equipment, which are obtained by the process emission calculation unit 44 for each of the multiple main equipment corresponding to the multiple processes for manufacturing the target product of the target type, and the total amount of raw material CO2 emissions related to the raw materials in the manufacture of the target product of the target type, which is obtained by the raw material emission calculation unit 42, and uses this as the total amount of target product CO2 emissions related to the target product of the target type. For example, in the case where the product of product No. "P001" is the target product of the target type, the target product emission calculation unit 49 obtains the sum of the process CO2 emissions of "9.1" [tCO2] of the main equipment with the equipment name "casting 1", the process CO2 emissions of "0.8" [tCO2] of the main equipment with the equipment name "rolling 1", the process CO2 emissions of "0.9" [tCO2] of the main equipment with the equipment name "rolling 2", the process CO2 emissions of "0.66" [tCO2] of the main equipment with the equipment name "heat treatment", and the process CO2 emissions of "0.2" [tCO2] of the main equipment with the equipment name "cutting 1", which are obtained as described above, and the total amount of "31.2" [tCO2] of the raw material CO2 emissions related to the raw materials of the product of product No. "P001", which is obtained as described above, and the sum of "42.86" [tCO2], and uses this as the total amount of target product CO2 emissions related to the product of product No. "P001".

[0096] Here, in the present embodiment, the object product emissions calculation unit 49 also adds the total amount of the incidental process CO2 emissions in the specified process performed on the object products of the object type calculated by the incidental process emissions calculation unit 46 and the total amount of the second remaining CO2 emissions related to the remaining emission sources in the manufacture of the object products of the object type calculated by the second remaining emissions calculation unit 48 to the total amount of the object product CO2 emissions related to the object products of the object type obtained, thereby obtaining a new total amount of the object product CO2 emissions related to the object products of the object type. That is, in the present embodiment, the object product emissions calculation unit 49 obtains the sum of the CO2 emissions of each process in the process performed by the main equipment obtained by the process emissions calculation unit 44 for each of the multiple main equipment corresponding to the multiple processes used to manufacture the object products of the object type, the total amount of the raw material CO2 emissions related to the raw materials in the manufacture of the object products of the object type calculated by the raw material emissions calculation unit 42, the total amount of the incidental process CO2 emissions in the specified process performed on the object products of the object type calculated by the incidental process emissions calculation unit 46, and the total amount of the second remaining CO2 emissions related to the remaining emission sources in the manufacture of the object products of the object type calculated by the second remaining emissions calculation unit 48, and uses it as the total amount of the object product CO2 emissions related to the object products of the object type. For example, when the product of product No. “P001” is the object product of the object type, the total amount of the incidental process CO2 emissions “2” [tCO2] in the transportation process performed on the product of product No. “P001” calculated by the incidental process emissions calculation unit 46 as described above and the total amount of the second remaining CO2 emissions “1” [tCO2] related to the remaining emission sources in the manufacture of the product of product No. “P001” calculated by the second remaining emissions calculation unit 48 as described above are added to the total amount of the object product CO2 emissions “42.86” [tCO2] related to the product of product No. “P001” obtained as described above, thereby obtaining a new total amount of the object product CO2 emissions “45.86” [tCO2] related to the product of product No. “P001”.

[0097] In addition, in the above description, the total amount of the incidental process CO2 emissions in the specified process performed on the object products of the object type calculated by the incidental process emissions calculation unit 46 and the total amount of the second remaining CO2 emissions related to the remaining emission sources in the manufacture of the object products of the object type calculated by the second remaining emissions calculation unit 48 are both added, but it is also possible to add only one of them.

[0098] Further, in the present embodiment, the object product emission calculation unit 49 also calculates the sixth unit CO2 emission per unit product of the object product of the object type based on the total amount of the object product CO2 emissions of the object product of the object type obtained above and the total amount of the object product of the object type manufactured in the factory during the specified period. For example, when the product of product No. "P001" is the object product of the object type, by dividing the object product CO2 emissions "45.86" [tCO2] of the product of product No. "P001" obtained as described above by the production volume "20" [tons] of the product of product No. "P001", the sixth unit CO2 emission per unit product of the product of product No. "P001" is calculated as "2.293" [tCO2 / ton of product].

[0099] Then, the control unit 41 outputs the calculation results of each of the calculation units 42 to 49 from the output unit 2. For example, when the output unit 2 is a display device, the calculation results of each of the calculation units 42 to 49 are displayed on the screen of the display device. Or, for example, when the output unit 2 is a printing device, the calculation results of each of the calculation units 42 to 49 are printed on paper by the printing device and output as a form. Figure 12 and Figure 13 One example is shown in Figure 12 is the screen or form of product No. "P001", Figure 13 is the screen or form of product No. "P002", in which the product No. of the product, the type (variety and customer) of the product, the process, the total amount of raw materials (actual value) during the specified period, the manufacturing load (weight, usage time) (actual value) of each process (each main equipment) during the specified period, the second unit CO2 emission per unit of each main equipment, the process CO2 emissions in the process performed by each main equipment during the specified period, the total amount of incidental process CO2 emissions in transportation processing, the fourth unit CO2 emission per unit product of the remaining emission source, the total amount of the second remaining CO2 emissions related to the remaining emission source, the total amount of object product CO2 emissions, and the sixth unit CO2 emission per unit product are shown respectively.

[0100] In addition, the control unit 41 may also output the calculation results of each of the calculation units 42 to 49 to an external device via the IF unit 3 as needed.

[0101] The input unit 1, output unit 2, IF unit 3, control processing unit 4, and storage unit 5 in the carbon dioxide emission calculation device S as an example of the carbon dioxide emission calculation system may be constituted by a computer such as a desktop or notebook type, for example. Of course, as described above, the carbon dioxide emission calculation system may also be constituted by multiple computers that can be communicatively connected.

[0102] Next, the operation of this embodiment will be described. Figure 14 It is a flowchart showing the operation of the carbon dioxide emission calculation system (a carbon dioxide emission calculation device as an example thereof).

[0103] Once the power of the carbon dioxide emission calculation device S configured as such is turned on, it initializes each necessary part and starts operating. By executing its control processing program, the control unit 41, raw material emission calculation unit 42, main equipment unit emission calculation unit 43, process emission calculation unit 44, emission allocation calculation unit 45, incidental process emission calculation unit 46, first remaining emission calculation unit 47, second remaining emission calculation unit 48, and target product emission calculation unit 49 are functionally configured in the control processing unit 4.

[0104] If the carbon dioxide emission calculation device S receives the input of a target product of one target type by a user (operator), it starts calculating the CO2 emissions of the target product of the target type. Additionally, all products of various types produced this period can also be the objects of CO2 emission calculation. In this case, the following respective processes S1 to S8 for a target product of one target type are repeatedly executed for each product of each type.

[0105] In Figure 14 firstly, the carbon dioxide emission calculation device S causes the raw material emission calculation unit 42 of the control processing unit 4 to obtain the total amount of raw material CO2 emissions related to the raw materials in the manufacture of the target product of the target type (S1).

[0106] Next, the carbon dioxide emission calculation device S causes the emission allocation calculation unit 45 of the control processing unit 4 to obtain the CO2 emission allocation amount of each device using auxiliary equipment for each of the multiple devices using auxiliary equipment (S2).

[0107] Next, the carbon dioxide emission calculation device S causes the main equipment unit emission calculation unit 43 of the control processing unit 4 to obtain the second unit CO2 emission per unit of each main equipment corresponding to multiple processes for manufacturing the target product of the target type (S3).

[0108] Next, the carbon dioxide emission calculation device S causes the process emission calculation unit 44 of the control processing unit 4 to obtain the process CO2 emissions in the processes performed by the main equipment for manufacturing the target product of the target type for each of the multiple main equipment corresponding to multiple processes for manufacturing the target product of the target type (S4).

[0109] Next, the carbon dioxide emissions calculation device S causes the incidental process emissions calculation unit 46 of the control processing unit 4 to obtain the total amount of CO2 emissions in the incidental processes in the specified process performed on the target product of the target type (S5).

[0110] Next, the carbon dioxide emissions calculation device S causes the first remaining emissions calculation unit 47 and the second remaining emissions calculation unit 48 of the control processing unit 4 to obtain the fourth unit CO2 emissions per unit product of the remaining emission sources, and obtains the total amount of the second remaining CO2 emissions of the remaining emission sources related to the target products of the target type (S6).

[0111] Next, the carbon dioxide emissions calculation device S causes the target product emissions calculation unit 49 of the control processing unit 4 to obtain the total amount of target product CO2 emissions related to the target products of the target type (S7).

[0112] Then, the carbon dioxide emissions calculation device S causes the control unit 41 of the control processing unit 4 to output the calculation results of the respective calculation units 42 to 49 from the output unit 2 (S8), and ends this process.

[0113] As described above, the carbon dioxide emissions calculation system (the carbon dioxide emissions calculation device as an example thereof) S of the embodiment and the carbon dioxide emissions calculation method installed in this system can obtain the carbon dioxide emissions for each target product of each target type even without the above-described association.

[0114] In a factory (workshop), the total data (actual values) during a specified period is managed in many cases. The above carbon dioxide emission calculation system (carbon dioxide emission calculation device) S and carbon dioxide emission calculation method. First, for each of the multiple main devices corresponding to the multiple processes for manufacturing the target products of the target type, based on the total amount of the manufacturing load applied to the main device during the manufacturing in the specified period and the total amount of the CO2 emissions of the main device related to the total amount of the manufacturing load, the second unit CO2 emissions per unit of the main device are obtained. Since the second unit CO2 emissions per unit of the main device are known, the above carbon dioxide emission calculation system (carbon dioxide emission calculation device) S and carbon dioxide emission calculation method can, for each of the multiple main devices corresponding to the multiple processes for manufacturing the target products of the target type, based on the second unit CO2 emissions per unit of the main device obtained as described above and the total amount of the manufacturing load applied to the main device for manufacturing the target products of the target type during the manufacturing in the specified period, obtain the total process CO2 emissions related to the process performed in the main device for manufacturing the target products of the target type. Therefore, the above carbon dioxide emission calculation system (carbon dioxide emission calculation device) S and carbon dioxide emission calculation method can calculate the carbon dioxide emissions for each target product of each target type even without the above-mentioned correlation.

[0115] In particular, in a factory (multi-product manufacturing factory) capable of manufacturing multiple types of products through multiple processes, since usually multiple processes are different according to the types of products, if the total amount of carbon dioxide emissions of the entire factory is simply evenly distributed to each product, the carbon dioxide emissions of each product cannot be obtained. The above carbon dioxide emission calculation system (carbon dioxide emission calculation device) S and carbon dioxide emission calculation method obtain the second unit CO2 emissions per unit of each of the multiple main devices corresponding to the multiple processes (i.e., the unit CO2 emissions of each process), so even when the factory is a multi-product manufacturing factory, the carbon dioxide emissions of each product can be obtained.

[0116] Since auxiliary devices are used for multiple devices, the total amount of the auxiliary device CO2 emissions of the auxiliary device during the specified period cannot be directly allocated to the target products of the target type. The above carbon dioxide emission calculation system (carbon dioxide emission calculation device) S and carbon dioxide emission calculation method can allocate the total amount of the auxiliary device CO2 emissions of the auxiliary device during the specified period to each of the multiple devices using the auxiliary device at a specified ratio, so it can be allocated to the target products of the target type.

[0117] The above carbon dioxide emissions calculation system (carbon dioxide emissions calculation device) S and the carbon dioxide emissions calculation method can take into account the total amount of CO2 emissions from the incidental processes in the designated processes performed on the product during the period from after the manufacture of the product to the delivery to the delivery destination in the carbon dioxide emissions of the product of each object type.

[0118] The above carbon dioxide emissions calculation system (carbon dioxide emissions calculation device) S and the carbon dioxide emissions calculation method can take into account the total amount of the remaining CO2 emissions from the remaining emission sources in the carbon dioxide emissions of the product of each object type.

[0119] Since the above carbon dioxide emissions calculation system (carbon dioxide emissions calculation device) S and the carbon dioxide emissions calculation method obtain the sum of the total amount of CO2 emissions from each process in the processes performed by the main equipment, which is obtained for each main equipment corresponding to the multiple processes used to manufacture the product of the object type, and the total amount of raw material CO2 emissions of the raw materials related to the manufacture of the product of the object type, they can obtain the total amount of object product CO2 emissions of the product of the object type. As described above, when the main equipment uses auxiliary equipment, the CO2 emissions of the auxiliary equipment are included in the CO2 emissions of each process in the processes performed by the main equipment. Therefore, the above carbon dioxide emissions calculation system (carbon dioxide emissions calculation device) S and the carbon dioxide emissions calculation method can take into account the CO2 emissions of the auxiliary equipment and obtain the total amount of object product CO2 emissions of the product of the object type. Here, in the present embodiment, the above carbon dioxide emissions calculation system (carbon dioxide emissions calculation device) S and the carbon dioxide emissions calculation method also add the total amount of CO2 emissions from the incidental processes in the designated processes performed on the product of the object type, which is obtained by the incidental process emissions calculation unit 46, and the total amount of the second remaining CO2 emissions from the remaining emission sources of the product of the object type, which is obtained by the second remaining emissions calculation unit 48, to the total amount of object product CO2 emissions of the product of the object type, which is obtained, and obtain a new total amount of object product CO2 emissions of the product of the object type. Therefore, the above carbon dioxide emissions calculation system (carbon dioxide emissions calculation device) S and the carbon dioxide emissions calculation method can take into account the CO2 emissions from the designated processes performed on the product during the period from after the manufacture of the product to the delivery to the delivery destination and the CO2 emissions from the remaining emission sources and obtain the total amount of object product CO2 emissions of the product of the object type.

[0120] When manufacturing a product from raw materials through multiple processes, there may be materials (hereinafter referred to as "rejected batch materials") that are discarded because a certain failure occurs after the completion of any one of the multiple processes (including the case of ending midway through the process) and cannot be shipped as a product. Since such rejected batch materials are also accompanied by carbon dioxide emissions, it is necessary to consider the CO2 emissions related to the rejected batch materials. In the above-described embodiment, since the CO2 emissions of the target product of the target type are calculated, the rejected batch materials that are not products cannot be directly regarded as the target products of the target type, so the CO2 emissions related to the rejected batch materials cannot be taken into account. In response to this, in the above-described embodiment, the CO2 emissions related to the rejected batch materials can be added to the CO2 emissions of the target product of the target type by any one of the first to fourth additional methods as described later, so as to take into account the CO2 emissions related to the rejected batch materials. Hereinafter, this modified embodiment will be described in more detail. In addition, in each of these first to fourth additional methods, the control unit 41, the raw material emissions calculation unit 42, the main equipment unit emissions calculation unit 43, the process emissions calculation unit 44, the emission allocation calculation unit 45, the incidental process emissions calculation unit 46, the first remaining emissions calculation unit 47, the second remaining emissions calculation unit 48, and the target product emissions calculation unit 49 in the control processing unit 4 also function as described in the above-described embodiment.

Figure 16 It is a diagram for explaining the second additional method of the modified embodiment. Figure 17 It is a diagram for explaining the third additional method of the modified embodiment. Figure 18 It is a diagram for explaining the fourth additional method of the modified embodiment. In these Figures 15 to 18 figures, Figure A shows multiple processes for manufacturing the first product of Specification A, multiple main equipment respectively corresponding to the multiple processes, and the CO2 emissions of each of the multiple processes; Figure B shows multiple processes for manufacturing the second product of Specification B, multiple main equipment respectively corresponding to the multiple processes, and the CO2 emissions of each of the multiple processes; Figure C shows multiple processes for manufacturing the third product of Specification C, multiple main equipment respectively corresponding to the multiple processes, and the CO2 emissions of each of the multiple processes. Figure 15 E, Figure 16 D, Figure 17 D and Figure 18 D represent multiple processes for manufacturing the fifth product of Specification C, multiple main equipment respectively corresponding to the multiple processes, and the CO2 emissions of each of the multiple processes. These Figures 15 to 18Also shown are the total amount of raw materials and the total CO2 emissions of the raw materials, and transportation processing (shipping), which is regarded as one process as an example of the specified processing performed on the product from after the manufacture of the product to the delivery to the delivery destination, is also shown, as well as the total amount of the product and the total CO2 emissions of the product related to the product. Figure 15 D represents the total amount of the 4th product of Specification C and the total CO2 emissions of the product related to the 4th product.

[0122] Among these Figures 15 to 18 the 3rd product is the target product of the target type, and the 5th product is a rejected lot that cannot be shipped as a product due to a failure after the end of the 2nd process STe-2 among the 1st to 4th processes STe-1 to STe-4 and is discarded.

[0123] The 1st product of Specification A is in Figure 15 A to Figure 18 A. From raw material a, it goes through the 1st process STa-1 using Equipment 1 as the main equipment, the 2nd process STa-2 using Equipment 2 as the main equipment, the 3rd process STa-3 using Equipment 3 as the main equipment, and the 4th process STa-4 using Equipment 5 as the main equipment, and is shipped in the transportation processing process STa-S. The CO2 emissions of each of the 1st to 4th processes STa-1 to STa-4 are "2" [tCO2], "1" [tCO2], "3" [tCO2], and "3" [tCO2]. The total amount of its raw material CO2 emissions is "6" [tCO2], the total amount of the 1st product is "3" [tons], and the total amount of the product CO2 emissions related to the 1st product is "15" [tCO2].

[0124] The 2nd product of Specification B is in Figure 15 B to Figure 18 B. From raw material b, it goes through the 1st process STb-1 using Equipment 1 as the main equipment, the 2nd process STb-2 using Equipment 2 as the main equipment, the 3rd process STb-3 using Equipment 4 as the main equipment, and the 4th process STb-4 using Equipment 6 as the main equipment, and is shipped in the transportation processing process STb-S. The CO2 emissions of each of the 1st to 4th processes STb-1 to STb-4 are "2" [tCO2], "1" [tCO2], "2" [tCO2], and "1" [tCO2]. The total amount of its raw material CO2 emissions is "4" [tCO2], the total amount of the 2nd product is "2" [tons], and the total amount of the product CO2 emissions related to the 2nd product is "10" [tCO2].

[0125] The 3rd product of Specification C is in Figure 15 C to Figure 18In C, from raw material b, through the first process STc-1 using equipment 1 as the main equipment, the second process STc-2 using equipment 3 as the main equipment, the third process STc-3 using equipment 4 as the main equipment, and the fourth process STc-4 using equipment 5 as the main equipment, it is shipped in the transportation and processing process STa-S. The CO2 emissions of each process in the first to fourth processes STc-1 to STc-4 are "3" [tCO2], "2" [tCO2], "4" [tCO2], and "2" [tCO2]. The total amount of the third product is "5" [tons]. The total amount of its raw material CO2 emissions is "8" [tCO2], the total amount of the third product is "5" [tons], and the total amount of the product CO2 emissions related to the third product is "19" [tCO2].

[0126] The fourth product of specification C is in Figure 15 In D, the illustration of each process is omitted, its total amount is "2.5" [tons], and the total amount of the product CO2 emissions related to the fourth product is "8" [tCO2].

[0127] The fifth product of specification C is in Figure 15 E, Figure 16 D, Figure 17 D and Figure 18 In D, usually from raw material b, through the first process STe-1 using equipment 1 as the main equipment, the second process STe-2 using equipment 3 as the main equipment, the third process STe-3 using equipment 4 as the main equipment, and the fourth process STe-4 using equipment 5 as the main equipment, it is shipped in the transportation and processing process STe-S. However, in this example, after the second process STe-2 ends, due to a failure, it cannot be shipped as a product and becomes a rejected lot to be discarded. The CO2 emissions of each process in the first and second processes STe-1 and STe-2 are "1" [tCO2] and "2" [tCO2]. The total amount of its raw material CO2 emissions is "3" [tCO2].

[0128] These specifications A to C are different from each other. These equipment 1 to equipment 6 are different from each other. The CO2 emissions are basically the values before the addition, and by appropriately adding symbols It also represents the values after the addition.

[0129] First, the first addition method is described. In the first addition method, attention is paid to the type of product, and the total amount of the CO2 emissions of the rejected lot related to the rejected lot is considered. In the above-mentioned embodiment, the types of the products are classified according to the variety (specification) and the customer. Therefore, here, attention is paid to the variety of the product. The carbon dioxide emissions calculation system (a carbon dioxide emissions calculation device as an example) S using the first addition method is as Figure 1As shown by the dashed line in the figure, the control processing unit 4 also functionally includes a rejected lot emissions calculation unit 61 and an emissions addition calculation unit 62a.

[0130] The rejected lot emissions calculation unit 61 is used to obtain the total amount of rejected lot CO2 emissions related to the rejected lot.

[0131] In this modified embodiment, the raw material emissions calculation unit 42 also obtains the total amount of raw material CO2 emissions related to the raw materials in the manufacture of the rejected lot based on the first unit CO2 emissions per unit of the raw materials used in the manufacture of the rejected lot given and the total amount of the raw materials used in the manufacture of the rejected lot during the specified period. In Figure 15 the example shown in E, the raw material of the rejected lot is raw material b, and the total amount of raw material CO2 emissions related to this raw material b is "3" [tCO2].

[0132] In this modified embodiment, the process emissions calculation unit 44 also calculates, for one or more main devices corresponding to one or more processes that proceed to the discard among the multiple processes used to manufacture the rejected lot, the process CO2 emissions in the processes performed by the main device for manufacturing the rejected lot based on the second unit CO2 emissions per unit of the main device obtained by the main device unit emissions calculation unit and the total amount of the manufacturing load applied to the main device for manufacturing the rejected lot during the manufacture within the specified period. In Figure 15 the example shown in E, in the first process STe-1, device 1 is used as the main device, and the process CO2 emissions in the first process STe-1 performed by this device 1 are "1" [tCO2]. In the second process STe-2, device 3 is used as the main device, and the process CO2 emissions in the second process STe-2 performed by this device 3 are "2" [tCO2].

[0133] And, more specifically, the rejected lot emissions calculation unit 61 obtains the sum of one or more process CO2 emissions in the processes performed by the main devices obtained by the process emissions calculation unit 44 for one or more main devices corresponding to one or more processes that proceed to the discard among the multiple processes used to manufacture the rejected lot, and the total amount of raw material CO2 emissions related to the raw materials in the manufacture of the rejected lot obtained by the raw material emissions calculation unit 42, and takes this as the total amount of rejected lot CO2 emissions. In Figure 15In the example shown in E, find the sum "3" [tCO2] (= 1 + 2) of the process CO2 emissions "1" [tCO2] in the first process STe-1 and the process CO2 emissions "2" [tCO2] in the second process STe-2, and the sum "6" [tCO2] (= 3 + 3) of this sum "3" [tCO2] and the total amount "3" [tCO2] of the raw material CO2 emissions related to the second raw material b.

[0134] When the variety of the target product of the target type is the same as the variety of the rejected lot, the emissions addition calculation unit 62a adds a specified ratio (the first A ratio) in the total amount of the rejected lot CO2 emissions calculated by the rejected lot emissions calculation unit 61 to the total amount of the target product CO2 emissions calculated by the target product emissions calculation unit 49 for addition. The first A ratio is the ratio of the total amount of the target products of the target type to the total amount of the products (including the target products of the target type) of the same variety as the rejected lot manufactured during the specified period. Figure 15 In the example shown, the target product of the target type is Figure 15 the third product of specification C shown in C. Therefore, the variety (specification) C of this target product is the same as Figure 15 the variety (specification) C of the fifth product of the rejected lot shown in E. Therefore, the emissions addition calculation unit 62a first calculates the total amount "7.5" {tons} (= 5 + 2.5) of the products of variety C that are the same as the variety C of the fifth product of the rejected lot manufactured during the specified period (that is, the third and fourth products) in order to find the first A ratio, calculates the total amount "5" {tons} of the target products of the target type, that is, the third product, and calculates the first A ratio "5 / 7.5". Then, the emissions addition calculation unit 62a adds the amount "6×(5 / 7.5)" = "4" of the first A ratio "5 / 7.5" in the total amount "6" [tCO2] of the rejected lot CO2 emissions to the total amount "19" [tCO2] (= 8 + 3 + 2 + 4 + 2) of the target product CO2 emissions calculated by the target product emissions calculation unit 49 for addition. Therefore, the total amount of the target product CO2 emissions related to the third product after addition is "23" [tCO2] (= 19 + 4). In addition, when the fourth product is the target product of the target type, the remaining "2" [tCO2] in the total amount "6" [tCO2] of the rejected lot CO2 emissions is added as the amount "6×(2.5 / 7.5)" = "2" of the first A ratio "2.5 / 7.5" in the total amount "6" [tCO2] of the rejected lot CO2 emissions to the total amount "8" [tCO2] of the CO2 emissions related to the fourth product, and the total amount of the CO2 emissions related to the fourth product after addition is "10" [tCO2] (= 8 + 2).

[0135] In addition, in the first additional method, the first A ratio may be the ratio of the total amount of the object product CO2 emissions of the object products of the object type to the total amount of the product CO2 emissions of the products (including the object products of the object type) of the same variety as the variety of the rejected lot products manufactured during the specified period. For example, the first A ratio for the third product is 19 / (19 + 8) = 19 / 27.

[0136] The carbon dioxide emissions calculation device S can take into account the rejected lot CO2 emissions related to the rejected lot. When the product categories of the products are classified by variety and customer and the product category of the object products of the object type is the same as the variety of the rejected lot, the rejected lot CO2 emissions are taken into account in the total amount of the object product CO2 emissions.

[0137] In addition, in the above description, the types of products are classified by variety (specification) and customer (orderer). Even if multiple orders are received at different times, if the variety and customer are the same, the same product No is assigned to the multiple orders, and the products manufactured according to the multiple orders are grouped together. However, the types of products may also be classified by variety (specification). In this case, when the object type is the same as the type of the rejected lot, the emission additional calculation unit 62a adds a specified ratio (the first A' ratio) in the total amount of the rejected lot CO2 emissions calculated by the rejected lot emissions calculation unit 61 to the total amount of the object product CO2 emissions calculated by the object product emissions calculation unit 49 for addition. The first A' ratio is the ratio of the total amount of the object products of the object type to the total amount of the products (including the object products of the object type) of the same type as the type of the rejected lot manufactured during the specified period. In addition, the first A ratio may be the ratio of the total amount of the object product CO2 emissions of the object products of the object type to the total amount of the product CO2 emissions of the products of the same variety as the variety of the rejected lot manufactured during the specified period. The rejected lot emissions calculation unit 61, the raw material emissions calculation unit 42, and the process emissions calculation unit 44 are the same as those described above. The carbon dioxide emissions calculation device S can take into account the rejected lot CO2 emissions related to the rejected lot. When the types of products are classified by variety (specification) and the type of the object products of the object type is the same as the type of the rejected lot, the rejected lot CO2 emissions are taken into account in the total amount of the object product CO2 emissions.

[0138] Next, the second addition method will be described. In the second addition method, attention is paid to the raw materials of the product, and the total amount of the rejected lot CO2 emissions related to the rejected lot is considered. The carbon dioxide emissions calculation system (a carbon dioxide emissions calculation device as an example) S that adopts the second addition method is as shown by the dashed line in Figure 1 and functionally further includes a rejected lot emissions calculation unit 61 and an emissions addition calculation unit 62b in the control processing unit 4. The rejected lot emissions calculation unit 61, the raw material emissions calculation unit 42, and the process emissions calculation unit 44 in the carbon dioxide emissions calculation device S that adopts the second addition method are the same as the rejected lot emissions calculation unit 61, the raw material emissions calculation unit 42, and the process emissions calculation unit 44 in the carbon dioxide emissions calculation device S that adopts the first addition method, respectively, so their descriptions are omitted.

[0139] When the raw material of the target product of the target type is the same as the raw material of the rejected lot, the emissions addition calculation unit 62b adds a specified ratio (the B ratio) of the total amount of the rejected lot CO2 emissions obtained by the rejected lot emissions calculation unit 61 to the total amount of the target product CO2 emissions obtained by the target product emissions calculation unit 49 for addition. The B ratio is the ratio of the total amount of the raw material CO2 emissions related to the raw material of the target product of the target type to the total amount of the raw material CO2 emissions related to the raw material of the products (including the target product of the target type) that are the same as the raw material of the rejected lot manufactured during the specified period. In Figure 16 the example shown, the target product of the target and class is Figure 16 the third product of specification C shown in C, so the raw material b of this target product is the same as Figure 16The raw material b of the fifth product of the rejected lot shown in D is the same. Therefore, the emission additional calculation unit 62b first calculates the total amount "12" [tCO2] (=4 + 8) of the raw material CO2 emissions of the products (including the target products of the target type) of the raw material b that is the same as the raw material b of the rejected lot manufactured during the specified period in order to obtain the B ratio. Then, the emission additional calculation unit 62b calculates the total amount "8" [tCO2] of the raw material CO2 emissions of the target product, that is, the third product, of the target type with respect to the raw material, and calculates the B ratio "8 / 12 = 2 / 3". Then, the emission additional calculation unit 62b adds the amount "6×(2 / 3)" = "4" of the B ratio "2 / 3" in the total amount "6" [tCO2] of the rejected lot CO2 emissions to the total amount "19" [tCO2] (=8 + 3 + 2 + 4 + 2) of the target product CO2 emissions calculated by the target product emission calculation unit 49 for additional calculation. Therefore, the total amount of the target product CO2 emissions for the third product after the addition is "23" [tCO2]. Here, in Figure 16 In C, the amount "6×(2 / 3)" = "4" of the B ratio "2 / 3" in the total amount "6" [tCO2] of the rejected lot CO2 emissions is added to the total amount "8" [tCO2] of the raw material CO2 emissions related to the raw material in the manufacture of the third product for additional calculation. However, since the total amount of the target product CO2 emissions for the third product includes the total amount of the raw material CO2 emissions related to the raw material in the manufacture of the third product, the result of adding and calculating either of them is the same. In addition, when the second product is the target product of the target type, the remaining "2" [tCO2] in the total amount "6" [tCO2] of the rejected lot CO2 emissions is added as the amount "6×(1 / 3)" = "2" of the B ratio "1 / 3" in the total amount "6" [tC02] of the rejected lot CO2 emissions to the total amount "10" [tCo2] of the CO2 emissions related to the second product, and the total amount of the CO2 emissions related to the second product after the addition is "12" [tCO2].

[0140] In addition, in this second addition method, the B ratio may be the ratio of the total amount of the raw materials of the target products of the target type to the total amount of the raw materials of the products (including the target products of the target type) of the raw materials that are the same as the raw materials of the rejected lot manufactured during the specified period.

[0141] This carbon dioxide emission calculation device S can take into account the rejected lot CO2 emissions related to the rejected lot, and when the raw materials of the target products are the same as the raw materials of the rejected lot, take into account the rejected lot CO2 emissions in the total amount of the target product CO2 emissions.

[0142] Next, the third addition method will be described. In the third addition method, attention is paid to the equipment used in the process, and the total amount of CO2 emissions of the rejected lot related to the rejected lot is considered. The carbon dioxide emissions calculation system (a carbon dioxide emissions calculation device as an example) S adopting the third addition method is as shown by the dotted line in Figure 1 In the carbon dioxide emissions calculation device S adopting the third addition method, the rejected lot emissions calculation unit 61 and the emissions addition calculation unit 62c are also functionally included in the control processing unit 4. The rejected lot emissions calculation unit 61, the raw material emissions calculation unit 42, and the process emissions calculation unit 44 in the carbon dioxide emissions calculation device S adopting the third addition method are the same as the rejected lot emissions calculation unit 61, the raw material emissions calculation unit 42, and the process emissions calculation unit 44 in the carbon dioxide emissions calculation device S adopting the first addition method, respectively, so their descriptions are omitted.

[0143] When the emissions addition calculation unit 62c includes the same main equipment as one or more main equipment corresponding to one or more processes up to the discard in the multiple processes for manufacturing the rejected lot among the multiple main equipment corresponding to the multiple processes for manufacturing the object product of the object type, the emissions addition calculation unit 62c adds a specified ratio (the C ratio) of the total amount of the rejected lot CO2 emissions obtained by the rejected lot emissions calculation unit 61 to the process CO2 emissions in the process performed by this main equipment for manufacturing the object product of the object type obtained by the process emissions calculation unit 44. The C ratio refers to the ratio of the process CO2 emissions in the process performed by this main equipment for manufacturing the object product of the object type obtained by the process emissions calculation unit 44 to the sum of the process CO2 emissions in the process performed by this main equipment for the products (including the object products of the object type) manufactured during the specified period obtained by the process emissions calculation unit 44. That is, when there are multiple types of the same main equipment, for each of the multiple types, the process CO2 emissions in the process performed by this type of main equipment for the products (including the object products of the object type) manufactured during the specified period obtained by the process emissions calculation unit 44 are obtained, and the sum of the process CO2 emissions obtained for each of the multiple types is obtained. For each of the multiple types, the ratio of the process CO2 emissions in the process performed by this type of main equipment for manufacturing the object product of the object type obtained by the process emissions calculation unit 44 to this sum is obtained and used as the C ratio of this type of main equipment.

[0144] In Figure 17 the example shown, the object product of the object type isFigure 17The third product of Specification C shown in C. Therefore, the main equipment corresponding to the first to fourth processes STc-1 to STc-4 for manufacturing the target product is Equipment 1, Equipment 3, Equipment 4, and Equipment 5. The main equipment corresponding to the first and second processes STe-1 and STe-2 that proceed to the discard among the first to fourth processes STe-1 to STe-4 for manufacturing the rejected lot, that is, the fifth product, is Equipment 1 and Equipment 3. Therefore, the same equipment they have in common is Equipment 1 and Equipment 3. This Equipment 1 is respectively used for the first process STa-1 related to the first product, the first process STb-1 related to the second product, and the first process STc-1 related to the third product. The process CO2 emissions in these respective processes are "2" [tCO2], "2" [tCO2], and "3" [tCO2] respectively. This Equipment 3 is respectively used for the third process STa-3 related to the first product and the second process STc-2 related to the third product. The process CO2 emissions in these respective processes are "3" [tCO2] and "2" [tCO2] respectively. The emissions additional calculation unit 62c first, in order to obtain the C ratio, for the same main equipment, obtains the total "12" (= 2 + 2 + 3 + 3 + 2) [tCO2] of the process CO2 emissions in the processes performed by this main equipment obtained by the process emissions calculation unit for the products manufactured during the specified period. For Equipment 1, it obtains the process CO2 emissions "3" [tCO2] in the processes performed by this Equipment 1 for the target product of the target product type, that is, the third product, and obtains the C ratio "3 / 12" for this Equipment 1. For Equipment 3, it obtains the process CO2 emissions "2" [tCO2] in the processes performed by this Equipment 3 for manufacturing the third product, and obtains the C ratio "2 / 12" for this Equipment 3. Then, the emissions additional calculation unit 62c, for Equipment 1, adds the amount "6×(3 / 12)" = "1.5" of the C ratio "3 / 12" in the total "6" [tCO2] of the rejected lot CO2 emissions to the process CO2 emissions "3" [tCO2] in the processes performed by this Equipment 1 for manufacturing the third product and adds it as an addition. For Equipment 3, it adds the amount "6×(2 / 12)" = "1" of the C ratio "2 / 12" in the total "6" [tCO2] of the rejected lot CO2 emissions to the process CO2 emissions "2" [tCO2] in the processes performed by this Equipment 1 for manufacturing the third product and adds it as an addition. The process CO2 emissions in the first process STc-1 related to the third product after the addition are "4.5" [tCO2], and the process CO2 emissions in its second process STc-2 are "3" [tCO2]. Therefore, the total of the target product CO2 emissions related to the third product after the addition is "21.5" [tCO2].In addition, when the first and second products are the target products of the target type, the remaining "4.5" [tCO2] in the total CO2 emissions "6" [tCO2] of the rejected lot are added respectively.

[0145] In addition, in this third addition method, the C ratio may also be the ratio of the total manufacturing load applied to the main equipment for manufacturing the target product of the target type during manufacturing within the specified period to the total manufacturing load applied to the main equipment during manufacturing within the specified period for the products manufactured within the specified period (including the target product of the target type) with respect to the same main equipment.

[0146] The carbon dioxide emissions calculation device S can take into account the rejected lot CO2 emissions related to the rejected lot. When the main equipment for manufacturing the target product includes the same main equipment as the main equipment for manufacturing the rejected lot, for the same main equipment, the rejected lot CO2 emissions are taken into account in the process CO2 emissions in the process performed by the main equipment for manufacturing the target product of the target type.

[0147] Next, the fourth addition method will be described. In the fourth addition method, focusing on the equipment used when performing the process, for the equipment, the process CO2 emissions in the process performed by the equipment for manufacturing the rejected lot are considered. The carbon dioxide emissions calculation system (a carbon dioxide emissions calculation device as an example) S adopting this fourth addition method is as Figure 1 shown by the dotted line in the control processing unit 4 and functionally further includes an emissions addition calculation unit 62d. The raw material emissions calculation unit 42 and the process emissions calculation unit 44 in the carbon dioxide emissions calculation device S adopting this fourth addition method are the same as the raw material emissions calculation unit 42 and the process emissions calculation unit 44 in the carbon dioxide emissions calculation device S adopting the first addition method, respectively, so their descriptions are omitted.

[0148] When the additional emission calculation unit 62d includes, in a plurality of main apparatuses respectively corresponding to a plurality of processes for manufacturing the object product of the object type, the same main apparatus as one or more main apparatuses corresponding to one or more processes up to the discard among the plurality of processes for manufacturing the rejected lot, the additional emission calculation unit adds a specified first ratio of the process CO2 emissions in the process performed by the main apparatus for manufacturing the rejected lot, which is obtained by the process emission calculation unit 44, to the process CO2 emissions in the process performed by the same main apparatus for manufacturing the object product of the object type, which is obtained by the process emission calculation unit 44. The first ratio means the ratio of the process CO2 emissions in the process performed by the main apparatus for manufacturing the object product of the object type, which is obtained by the process emission calculation unit, to the total amount of the process CO2 emissions in the process performed by the main apparatus, which is obtained by the process emission calculation unit, for the products (including the object products of the object type) manufactured during the specified period. That is, when there are a plurality of types of the same main apparatus, for each of the plurality of types, the total amount of the process CO2 emissions in the process performed by the main apparatus of that type, which is obtained by the process emission calculation unit 44, for the products (including the object products of the object type) manufactured during the specified period is obtained, and the ratio of the process CO2 emissions in the process performed by the main apparatus of that type for manufacturing the object product of the object type, which is obtained by the process emission calculation unit 44, to the total amount is obtained and used as the first ratio of the main apparatus of that type. That is to say, in this fourth additional method, for each type of apparatus, the additional emission is added by adding a specified first ratio of the process CO2 emissions in the process performed by the main apparatus of that type for manufacturing the rejected lot.

[0149] In Figure 18 the example shown, the object product of the object type is Figure 18The third product of Specification C shown in C. Therefore, the main devices corresponding to the first to fourth processes STc-1 to STc-4 for manufacturing the target product are Device 1, Device 3, Device 4, and Device 5. The main devices corresponding to the first and second processes STe-1 and STe-2 that proceed to the discard among the first to fourth processes STe-1 to STe-4 for manufacturing the rejected lot, i.e., the fifth product, are Device 1 and Device 3. Therefore, the same devices they have in common are Device 1 and Device 3. This Device 1 is respectively used for the first process STa-1 related to the first product, the first process STb-1 related to the second product, and the first process STc-1 related to the third product. The process CO2 emissions in these respective processes are "2" [tCO2], "2" [tCO2], and "3" [tCO2] respectively. This Device 3 is respectively used for the third process STa-3 related to the first product and the second process STc-2 related to the third product. The process CO2 emissions in these respective processes are "3" [tCO2] and "2" [tCO2] respectively. First, the emissions additional calculation unit 62d calculates the total amount of process CO2 emissions "7" (= 2 + 2 + 1) [tCO2] in the processes performed by this Device 1 as calculated by the process emissions calculation unit 44 for the products manufactured during the specified period in order to obtain the first ratio for Device 1, calculates the process CO2 emissions "3" [tCO2] in the processes performed by this Device 1 for the target product of the target product type, i.e., the third product, calculates the first ratio "3 / 7" for this Device 1, and adds the amount "1×(3 / 7)" = "0.43" (rounded to the third decimal place, the same below) of the first ratio "3 / 7" for this Device 1 in the process CO2 emissions "1" [tCO2] in the processes performed by this Device 1 for manufacturing the rejected lot to the process CO2 emissions "3" [tCO2] in the processes performed by this Device 1 for manufacturing the third product for addition. Then, the emissions additional calculation unit 62d calculates the total amount of process CO2 emissions "5" (= 3 + 2) [tCO2] in the processes performed by this Device 3 as calculated by the process emissions calculation unit 44 for the products manufactured during the specified period in order to obtain the first ratio for Device 3, calculates the process CO2 emissions "2" [tCO2] in the processes performed by this Device 3 for the target product of the target product type, i.e., the third product, calculates the first ratio "2 / 5" for this Device 3, and adds the amount "2×(2 / 5)" = "0.8" of the first ratio "2 / 5" for this Device 3 in the process CO2 emissions "2" [tCO2] in the processes performed by this Device 3 for manufacturing the rejected lot to the process CO2 emissions "2" [tCO2] in the processes performed by this Device 3 for manufacturing the third product for addition.The process CO2 emissions in the first process STc-1 for the third product after addition is "3.43" [tCO2], and the process CO2 emissions in the second process STc-2 is "2.8" [tCO2]. Therefore, the total amount of the target product CO2 emissions for the third product after addition is "20.23" [tCO2]. However, the raw material CO2 emissions related to the raw materials in the manufacture of the rejected lot have not been added yet, and the addition will be described later. In addition, the remaining "4 / 7" [tCO2] of the "1" [tCO2] of the process CO2 emissions in the processes performed by the equipment 1 for manufacturing the rejected lot is added respectively when the first and second products are target products of the target type. The remaining "1.2" [tCO2] of the "2" [tCO2] of the process CO2 emissions in the processes performed by the equipment 3 for manufacturing the rejected lot is added when the first product is a target product of the target type.

[0150] In addition, in the fourth addition method, the first ratio may be the ratio of the total manufacturing load applied to the main equipment for manufacturing the target product of the target type during the manufacturing within the specified period to the total manufacturing load applied to the main equipment for the products (including the target product of the target type) manufactured during the manufacturing within the specified period within the specified period.

[0151] And, when the types of the products are classified by variety and customer, and the variety of the target product of the target type is the same as the variety of the rejected lot, the emissions addition calculation unit 62d also adds a specified second ratio in the total amount of the raw material CO2 emissions related to the raw materials in the manufacture of the rejected lot obtained by the raw material emissions calculation unit 42 to the total amount of the target product CO2 emissions obtained by the target product emissions calculation unit 49 for addition. The second ratio is the ratio of the total amount of the target product of the target type to the total amount of the products (including the target product of the target type) of the same variety as the rejected lot manufactured during the specified period. In addition, the second ratio may be the ratio of the total amount of the target product CO2 emissions related to the target product of the target type to the total amount of the product CO2 emissions related to the products (including the target product of the target type) of the same variety as the rejected lot manufactured during the specified period. The second ratio is obtained by the same method as the first ratio A in the first addition method.

[0152] In Figure 18 the example shown, the target product of the target type is Figure 18 the third product of specification C shown in C, and the raw material b of the target product is the same as Figure 18The raw material b of the fifth product of the rejected lot shown in D is the same. Therefore, first, in order to calculate the second ratio, the emission amount additional calculation unit 62d calculates the total amount of product CO2 emissions of products (including the target products of the target type) made of the same raw material b as the raw material b of the rejected lot during the specified period (i.e., the second and third products), which is "29" [tons] (= 10 + 19). Then, it calculates the total amount of target product CO2 emissions of the target product of the target type, that is, the third product, which is "19" [tCO2] (= 8 + 3 + 2 + 4 + 2), and calculates the second ratio "19 / 29". Then, the emission amount additional calculation unit 62d adds the amount of "3×(19 / 29)" = "1.97" of the second ratio "19 / 29" in the total amount of raw material CO2 emissions of "3" [tCO2] related to the raw material in the production of the rejected lot calculated by the raw material emission amount calculation unit 42 to the total amount of target product CO2 emissions of "19" [tCO2] calculated by the target product emission amount calculation unit 49 for additional calculation. Therefore, the total amount of target product CO2 emissions related to the third product after addition is "22.2" [tCO2] (= 20.23 + 1.97). In addition, the remaining "3×(10 / 29)" [tCO2] in the total amount of raw material CO2 emissions of "3" [tCO2] related to the raw material in the production of the rejected lot is added when the second product becomes the target product of the target type.

[0153] In addition, in the fourth additional method, when the type of the object and the type of the rejected lot are the same, the emission additional calculation unit 62d may add a specified third ratio of the total amount of the raw material CO2 emissions related to the raw materials in the manufacture of the rejected lot obtained by the raw material emission calculation unit 42 to the total amount of the object product CO2 emissions obtained by the object product emission calculation unit 49 for additional calculation. Alternatively, when the raw materials of the object product of the object type and the raw materials of the rejected lot are the same, the emission additional calculation unit 62d may add a specified fourth ratio of the total amount of the raw material CO2 emissions related to the raw materials in the manufacture of the rejected lot obtained by the raw material emission calculation unit 42 to the total amount of the object product CO2 emissions obtained by the object product emission calculation unit 49 for additional calculation. The third ratio is the ratio of the total amount of the object products of the object type to the total amount of the products of the same type as the rejected lot (including the object products of the object type) manufactured during the specified period, or the ratio of the total amount of the object product CO2 emissions related to the object products of the object type to the total amount of the product CO2 emissions related to the products of the same variety as the rejected lot manufactured during the specified period. The third ratio is obtained by the same method as the ratio A' in the first additional method. The fourth ratio is the ratio of the total amount of the object products of the object type to the total amount of the products of the same raw material as the rejected lot (including the object products of the object type) manufactured during the specified period, or the ratio of the total amount of the raw material CO2 emissions related to the raw materials of the object type to the total amount of the raw material CO2 emissions related to the products of the same raw material as the rejected lot manufactured during the specified period. The fourth ratio is obtained by the same method as the ratio B in the second additional method.

[0154] The carbon dioxide emission calculation device S can take into account the rejected lot CO2 emissions related to the rejected lot. When the main equipment used to manufacture the object product includes the same main equipment as the main equipment used to manufacture the rejected lot, for the same main equipment, the process CO2 emissions in the process performed by this main equipment for manufacturing the object product of the object type are considered to include the process CO2 emissions in the process performed by this main equipment for manufacturing the rejected lot.

[0155] In addition, there may be parts in the raw materials that are not converted into products in certain processes (so-called processing waste), such as wood chips and fragments. Even in the case where such processing waste exists, since the CO2 emissions related to the processing waste are also included in the process CO2 emissions in the processes related to the processing waste, the above-described first to fourth additional methods can be applied.

[0156] This application is based on Japanese Patent Application No. 2022-193236 filed on December 2, 2022 and Japanese Patent Application No. 2023-4652 filed on January 16, 2023, the contents of which are incorporated herein.
