[0017] The present invention will be described below through embodiments of the invention, but the following embodiments do not limit the scope of the invention according to the claims. Furthermore, not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0018] FIG. 1 is a diagram showing an example of a production line to which a GHG emission deriving device 200 of the present embodiment may be applied. Three production lines 1 to 3 produce a plurality of types of products through a first production process to a third production process. A01 ~10 A18 (hereinafter, sometimes collectively referred to as manufacturing equipment 10) are each equipped with a measuring instrument 20 M01 ~20 M18(hereinafter, may be collectively referred to as measuring instruments 20.) are attached to each manufacturing apparatus 10. Each measuring instrument 20 measures the amount of electricity, gas, oil or water used by each manufacturing apparatus 10. Each measuring instrument 20 and GHG emission derivation device 200 are communicatively connected. Based on the amount of electricity, gas, oil or water used by each manufacturing apparatus 10 measured by each measuring instrument 20, GHG emission derivation device 200 derives the greenhouse gas emissions (GHG emissions) of products manufactured through the first to third manufacturing processes for each type of product.

[0019] 2 is a functional block diagram of the GHG emission amount deriving device 200. The GHG emission amount deriving device 200 includes a communication unit 230, a display unit 240, a storage unit 220, and a control unit 210.

[0020] The communication unit 230 manages communication between the components in the GHG emission amount deriving device 200. The communication unit 230 also communicates with an external computer via the Internet or the like.

[0021] The storage unit 220 stores a program and the like required to derive GHG emissions. The storage unit 220 also stores an activity amount allocation information table described below. The storage unit 220 may also store emission coefficients for electricity, gas, oil, and water. The storage unit 220 may also store measurement value data measured by each measuring device 20. The storage unit 220 includes, for example, a random access memory (RAM), a read-only memory (ROM), a dynamic RAM (DRAM), a synchronous DRAM (SD-RAM), a flash memory, a volatile memory, a non-volatile memory, a cache memory, a buffer, a short-term memory unit, a long-term storage device, or other suitable memory unit. The storage unit 220 includes, for example, a hard disk drive, a floppy disk drive, a compact disk (CD) drive, a CD-ROM drive, a DVD drive, or other suitable removable or non-removable storage unit.

[0022] The control unit 210 controls the entire GHG emission amount derivation device 200.

The control unit 210 has an acquisition unit 212, a derivation unit 214, a change acceptance unit 216, and an information provision unit 218.

[0023] In recent years, it is desired to accurately derive the amount of GHG emissions emitted in association with the activities of products and services in an organization. For example, it is known that the amount of electricity used by facilities and equipment measured by a meter or the like is acquired, and the amount of electricity used is multiplied by a greenhouse gas (GHG) emission factor to calculate GHG emissions. Incidentally, GHG emissions are derived by aggregating the amount of activity generated by the activities of an organization such as a company or group by organization unit, or are derived as a series of life cycle evaluation values ​​by the unit of products and services produced and provided by the organization, or are derived for carbon footprinting. Here, for example, when a plurality of manufacturing devices are operated in a factory of an organization to produce and process products, it is desirable to specify which product each manufacturing device was used for and contributed to the GHG emissions of the product. Therefore, in this embodiment, when a plurality of manufacturing devices 10 are operated in a factory of an organization to manufacture products, a GHG emission derivation device 200 is provided that can easily grasp which product each manufacturing device 10 contributed to the GHG emissions of.

[0024] Hereinafter, the GHG emission deriving device 200 of this embodiment will be described with reference to FIG. 1 again. In the description, it is assumed that five types of products, A, B, C, D, E, and F, are manufactured in a factory Y of an organization X. The products A, B, C, D, E, and F are any products, such as daily necessities, electrical appliances, chemical products, industrial products, vehicles, and food products. The first and second bases correspond to the respective manufacturing bases in the factory Y. The manufacturing line 1 manufactures the products A, B, and C. The manufacturing line 2 manufactures the products D and E. The manufacturing line 3 manufactures the product F. However, the final process of the manufacturing lines 2 and 3 is carried out by the manufacturing equipment 10 of the manufacturing line 1. A18In the manufacturing line, the raw materials, materials, parts (single parts or components) and other items used in the manufacture of each product are subjected to various manufacturing processes (including processing, assembly, firing, sorting, packaging, etc.). Information on the various raw materials, materials, parts and other items to be manufactured may be acquired by linking to databases in each industry. For example, IMDS (trademark), a material database for the automobile industry, may be used as the database. In this embodiment, the factory operates for 25 days per month. In the manufacturing line 1, product A is manufactured for 10 days, product B for 10 days, and product C for 5 days out of the 25 operating days. In the manufacturing line 2, product D is manufactured for 10 days and product E for 15 days out of the 25 operating days. In the manufacturing line 3, product F is manufactured for 25 days out of the 25 operating days.

[0025] Products A, B, and C are manufactured by manufacturing equipment 10 A01 and manufacturing equipment 10 A04 After that, the products A, B, and C are subjected to the first manufacturing process using the manufacturing equipment 10. A06 , manufacturing equipment 10 A08 , manufacturing equipment 10 A11 and manufacturing equipment 10 A14 Finally, the products A, B and C are subjected to a second manufacturing process using the manufacturing equipment 10. A15 and manufacturing equipment 10 A18 Products A, B, and C are produced through the third manufacturing process using

[0026] Products D and E are manufactured by manufacturing equipment 10 A02 After that, the products D and E are subjected to the first manufacturing process using the manufacturing device 10. A07 , manufacturing equipment 10 A09 and manufacturing equipment 10 A12 Finally, the products D and E are subjected to a second manufacturing process using the manufacturing apparatus 10. A16 and manufacturing equipment 10 A18 Products D and E are produced through the third manufacturing process using

[0027] Product F is manufactured by manufacturing equipment 10 A03 and manufacturing equipment 10 A05After that, the product F is subjected to the first manufacturing process using the manufacturing device 10. A10 and manufacturing equipment 10 A13 Finally, the product F is subjected to a second manufacturing process using the manufacturing device 10. A17 and manufacturing equipment 10 A18 Product F is produced through the third manufacturing process using

[0028] Each manufacturing device 10 is equipped with a measuring device 20. Each measuring device 20 measures the amount of electricity, gas, oil, or water consumed for the production of each product. A01 , manufacturing equipment 10 A02 , manufacturing equipment 10 A03 , manufacturing equipment 10 A04 , manufacturing equipment 10 A06 , manufacturing equipment 10 A08 , manufacturing equipment 10 A11 , manufacturing equipment 10 A14 , manufacturing equipment 10 A15 , manufacturing equipment 10 A16 , manufacturing equipment 10 A17 and manufacturing equipment 10 A18 is a device that uses electricity. In particular, manufacturing equipment 10 A18 The solar power generation device also operates on power supplied from a solar power generation device. The solar power generation device connects the power generated by the solar power generation module to the power grid of a power company via an inverter, and the power generated by the solar power generation module is given priority to the power generation of the manufacturing device 10. A18 Manufacturing equipment 10 A18 The manufacturing equipment 10 operates by receiving power from the power grid (purchasing power) to make up for the power shortage that cannot be covered by the power generated by the photovoltaic power generation module alone. In addition, the photovoltaic power generation device reverse flows (sells) surplus power to the power grid. A05 and manufacturing equipment 10 A10 is an equipment that uses oil. Manufacturing equipment 10 A07 , manufacturing equipment 10 A12 and manufacturing equipment 10 A13 is a device that uses water. Manufacturing equipment 10 A09 is a device that uses gas.

[0029] Now, how the GHG emission deriving device 200 according to this embodiment functions will be described in relation to the manufacture of product A in a certain month.

[0030] The acquisition unit 212 acquires activity amount information indicating the amount of activity from a plurality of measuring devices 20 that measure the amount of activity indicating the scale of each activity performed in relation to the manufacture of at least one type of product. The acquisition unit 212 reads and collects the measurement value data from each measuring device 20 stored in the storage unit 220. The measuring devices 20 of the manufacturing equipment involved in the manufacture of the product A are M01 , Measuring Instruments 20 M04 , Measuring Instruments 20 M06 , Measuring Instruments 20 M08 , Measuring Instruments 20 M11 , Measuring Instruments 20 M14 , Measuring Instruments 20 M15 and measuring instruments 20 M18 The measured values ​​of these measuring instruments collected by the acquisition unit 212 over the course of 25 working days were as follows: Measuring Instruments 20 M01 The electricity consumption measured by is 1000kWh. Measuring Instruments 20 M04 The electricity consumption measured by is 1000kWh. Measuring Instruments 20 M06 The electricity consumption measured by is 1000kWh. Measuring Instruments 20 M08 The electricity consumption measured by is 1000kWh. Measuring Instruments 20 M11 The electricity consumption measured by is 1000kWh. Measuring Instruments 20 M14 The electricity consumption measured by is 1000kWh. Measuring Instruments 20 M15 The electricity consumption measured by is 1000kWh. Measuring Instruments 20 M18 The electricity consumption measured by is 1000kWh.

[0031] The derivation unit 214 derives the GHG emission amount of each activity performed for the production of each product type based on the activity amount information and the activity amount information indicating at least one product type and the ratio of the activity amount to be allocated to at least one product for allocating each activity amount measured by the multiple measuring devices 20. Specifically, the derivation unit 214 reads the activity amount allocation information tables shown in FIG. 3A, FIG. 3B, FIG. 3C, and FIG. 3D stored in the storage unit 220. The activity amount allocation information table may be created by allocating the measuring device and the production time or the number of days to each type of product in advance based on the production plan. The activity amount allocation information table may be created by allocating the measuring device 20 and the production time or the number of days to each type of product as the actual results based on the classification and counting of the items that actually passed through the production line. The storage unit 220 may store the activity amount allocation information tables shown in FIG. 3A, FIG. 3B, FIG. 3C, and FIG. 3D. The storage section 220 may store at least two of the activity amount allocation information tables shown in FIG. 3A, FIG. 3B, FIG. 3C, and FIG. 3D as one table. The activity amount allocation information table includes columns indicating products A to F in the column direction. The activity amount allocation information table includes columns indicating products A to F in the row direction. M01 ~ M18 According to the column for each product in the activity allocation information table, the measuring device 20 M01 , Measuring Instruments 20 M04 , Measuring Instruments 20 M06 , Measuring Instruments 20 M08 , Measuring Instruments 20 M11 , Measuring Instruments 20 M14 , Measuring Instruments 20 M15 and measuring instruments 20 M18 The ratio of product A to all of the above is 40%. The derivation unit 214 further reads the GHG emission coefficient for electricity stored in the memory unit 220. Here, the GHG emission coefficient for electricity is 0.441 (kg-CO2 / kWh). Therefore, the derivation unit 214 multiplies the electricity usage measured by these measuring devices 20 by the GHG emission coefficient for electricity and the ratio of product A to derive the GHG emissions due to activities consuming electricity carried out in relation to the manufacture of product A. The result is as follows. Measuring Instruments 20 M01:1000(kWh)×0.441(kg-CO2 / kWh)×40%=176.4(kg-CO2) Measuring Instruments 20 M04 :1000(kWh)×0.441(kg-CO2 / kWh)×40%=176.4(kg-CO2) Measuring Instruments 20 M06 :1000(kWh)×0.441(kg-CO2 / kWh)×40%=176.4(kg-CO2) Measuring Instruments 20 M08 :1000(kWh)×0.441(kg-CO2 / kWh)×40%=176.4(kg-CO2) Measuring Instruments 20 M011 :1000(kWh)×0.441(kg-CO2 / kWh)×40%=176.4(kg-CO2) Measuring Instruments 20 M014 :1000(kWh)×0.441(kg-CO2 / kWh)×40%=176.4(kg-CO2) Measuring Instruments 20 M018 :1000(kWh)×0.441(kg-CO2 / kWh)×40 / 300%=58.7(kg-CO2)

[0032] As described above, the derivation unit 214 derives the GHG emission amount due to the activity of consuming electricity performed in relation to the manufacture of the product A for each measuring device 20. The GHG emission amount derived for each type of product may be a value taking into account the yield. Here, the derivation unit 214 may use the activity amount obtained by subtracting the quantity of items removed as defective products from the total number of items manufactured in that type after the final process, among the activity amounts acquired by each measuring device 20, for deriving the GHG emission amount. In addition, the derivation unit 214 may identify defective products in each process and derive the GHG emission amount according to the activity amount used for the items excluding the defective products. Note that here, the derivation unit 214 may total the GHG emission amount derived for each measuring device 20. In addition, here, an example in which the derivation unit 214 uses the emission coefficient of electricity stored in the storage unit 220 has been described, but the derivation unit 214 may acquire the emission coefficient by communicating with an external computer via the communication unit 230, for example. In this embodiment, GHG emissions are calculated by multiplying the activity amount by the emission factor, but GHG emissions may be measured directly as the activity amount. The emission factor may be specific to each organization, base, production line, type of product, etc. (primary data). In this case, the emission factor may be expressed based on a value measured in advance by an experiment or the like. The emission factor may be based on an industry-related table or various accumulation formulas (secondary data). The emission factor of the secondary data may be used when the emission factor of the primary data cannot be used. As described above, the manufacturing equipment 10 A018 The solar power generation device also operates on electricity supplied from the solar power generation device. The emission coefficient of electricity generated by the solar power generation device is zero. For example, the amount of electricity generated by the solar power generation device is measured every month, the monthly average value is derived, and the result is stored in the storage unit 220. Then, the derivation unit 214 calculates the emission coefficient of the solar power generation device by measuring the amount of electricity generated by the solar power generation device every month, and stores the average value of the month in the storage unit 220. M018 GHG emissions may be derived by subtracting the monthly average amount of electricity generated by solar power from the measured value and multiplying the result by an emission factor.

[0033] In addition, a GHG absorption and fixation device may be provided in any manufacturing apparatus 10. The GHG absorption and fixation device is a device that absorbs and fixes CO2, and may absorb and fix CO2 by technologies such as CCS (carbon capture and storage), CCUS (carbon capture and storage), and DAC (direct air capture). The derivation unit 214 may subtract the amount of GHG emissions absorbed by the GHG absorption and fixation device when deriving the amount of GHG emissions. The derivation unit 214 may not subtract the amount of GHG emissions absorbed by the GHG absorption and fixation device when deriving the amount of GHG emissions, but may derive the amount of GHG reduction (for example, by carbon credits, etc.) to be offset from the total amount of GHG emissions when deriving the amount of GHG emissions. The amount of GHG emissions that can be absorbed by the GHG absorption and fixation device may be measured in advance by an experiment or the like, and the amount of CO2 absorbed per hour may be stored in the storage unit 220. Alternatively, if the GHG absorption and fixation device can measure the amount of GHG absorption by itself, the acquisition unit 212 may acquire the amount of GHG absorption from the GHG absorption and fixation device. At least one GHG absorption and fixation device may be installed at each manufacturing process or each site.

[0034] According to this embodiment, each manufacturing apparatus 10 is provided with a measuring device 20, and the activity amount allocation information table specifies the ratio of each product to each measuring device 20. Therefore, when a plurality of manufacturing apparatuses 10 are operated to manufacture a plurality of products in a complex production line such as a factory, the amount of GHG emissions emitted by each manufacturing apparatus 20 in conjunction with the manufacture of each product can be accurately derived for each type of product.

[0035] The change receiving unit 216 receives changes to at least one of the types of products associated with each of the multiple measuring devices 20 indicated in the activity amount allocation information and the ratio of activity amounts allocated to the products. A user can add, delete, or change the types of products in the activity amount allocation information table via the change receiving unit 216. Similarly, a user can change the ratio of each product to each measuring device 20 in the activity amount allocation information table via the change receiving unit 216. The change receiving unit 216 may change the ratio of each product to each measuring device 20 in the activity amount allocation information table according to the type and number of ingredients, etc. passing through each measuring device 20, the operation time or number of days, etc.

[0036] The activity amount allocation information may further indicate an emission coefficient according to the type of activity to be measured for each of the multiple measuring devices 20. The derivation unit 214 may further derive the GHG emission amount based on the emission coefficient indicated in the activity amount allocation information. Specifically, as shown in FIG. 3A and FIG. 3B, the activity amount allocation information table includes the emission coefficients of electricity, gas, oil, and water. In the above-mentioned derivation of the GHG emission amount due to the activity consuming electricity performed in relation to the production of the product A by the derivation unit 214, the derivation unit 214 used the emission coefficient stored in the storage unit 220. Meanwhile, here, each emission coefficient is held in the activity amount allocation information table. The derivation unit 214 derives the GHG emission amount by multiplying the emission coefficient of electricity, gas, oil, or water held in the activity amount allocation information table by the electricity consumption amount, gas consumption amount, oil consumption amount, or water consumption amount measured by each measuring device 20, respectively. The derivation method is the same as that described above, and will not be repeated.

[0037] The change receiving unit 216 may receive changes to at least one of the types of products associated with each of the multiple measuring devices 20 indicated in the activity amount allocation information, the ratio of the activity amount allocated to the product, and the emission coefficient. A user can add, delete, or change the types of products in the activity amount allocation information table via the change receiving unit 216. Similarly, a user can change the ratio of each product to each measuring device in the activity amount allocation information table via the change receiving unit 216. Similarly, a user can add, delete, or change each emission coefficient in the activity amount allocation information table via the change receiving unit 216.

[0038] The information providing unit 218 causes the display unit 240 to display information indicating the GHG emission amount derived by the derivation unit 214. The display unit 240 may be separate from the GHG emission amount derivation device 200 and connected to the GHG emission amount derivation device 200 via a network. A display of a personal computer or a user terminal such as a smartphone may function as the display unit 240. The information providing unit 218 may cause the display unit 240 to display the GHG emission amount derived by the derivation unit 214 for each product type and for each of the multiple measuring instruments 20. The information providing unit 218 may cause the display unit 240 to display the GHG emission amount derived by the derivation unit 214 for each product type and for each of the multiple classifications described below.

[0039] The information providing unit 218 may cause the display unit 240 to display a list of the GHG emissions emitted by each manufacturing apparatus 10. The information providing unit 218 may cause the display unit 240 to display a list of the GHG emissions emitted by each manufacturing apparatus 10 for each category. The information providing unit 218 may cause the display unit 240 to display the GHG emissions emitted by each manufacturing apparatus 10 in parallel for the target year and the comparative year. The information providing unit 218 may cause the display unit 240 to display the GHG emissions emitted by each manufacturing apparatus 10 in parallel for the target year and the comparative year for each category. The information providing unit 218 may cause the display unit 240 to display the manufacturing apparatuses 10 that emit GHG emissions equal to or greater than a threshold value among the GHG emissions emitted by each manufacturing apparatus 10. The information providing unit 218 may cause the display unit 240 to display the manufacturing apparatuses 10 in order of the amount of GHG emissions, either high or low. The information providing unit 218 may display on the display unit 240 the manufacturing apparatus 10 that emits GHG emissions that are greater than the GHG emissions emitted by the manufacturing apparatuses 10 in the other manufacturing lines among a plurality of manufacturing lines that manufacture the same product through the same process. The information providing unit 218 may display on the display unit 240 the amount of activity (e.g., electricity usage) in any time unit, such as 1 second, 5 seconds, 30 seconds, 1 minute, 5 minutes, 30 minutes, 1 hour, or 6 hours. In this case, the information providing unit 218 may display on the display unit 240 the amount of GHG emissions in addition to the amount of activity in the same time unit. The information providing unit 218 may group certain measuring instruments 20 into groups for each manufacturing process, and display on the display unit 240 the activity amount allocation (ratio) for each type of product in a list or breakdown for each manufacturing process. The information providing unit 218 may cause the display unit 240 to display a list or a breakdown of activity amount allocations for each type of product for each device (e.g., a sequencer) equipped with a certain measuring device 20. The information providing unit 218 may cause the display unit 240 to display a list or a breakdown of activity amounts (electricity usage, water usage, gas usage, oil usage, and other activity amounts) that differ for each type of product.

[0040] The activities carried out in relation to the production of the product may be activities consuming at least one of electricity, gas, oil, and water. The amount of activity measured by the multiple measuring instruments 20 may be the amount of usage of any one of electricity, gas, oil, and water. In the above example, the activities carried out in relation to the production of product A were all activities consuming electricity. On the other hand, product D produced on production line 2 consumes water (measurement instrument 20) in the second production process in addition to the activities consuming electricity. M07 and measuring instruments 20 M12 ) and gas (instrument 20 M09 In addition to the electricity consumption, the product F manufactured on the manufacturing line 3 consumes oil (measurement device 20) in the first manufacturing process. M05 ) and oil (measuring instrument 20) in the second manufacturing process M10 ) and water (measurement instrument 20 M13 ). Activities carried out in relation to the manufacture of a product may be activities that consume fuels. Fuels may include solid fuels (metallurgical coal, steam coal, anthracite, coke, petroleum coke, briquettes or briquettes, wood, charcoal, other solid fuels), liquid fuels (coal tar, petroleum asphalt, condensate, crude oil (except condensate (NGL)), gasoline, naphtha, jet fuel oil, kerosene, diesel, A fuel oil, B and C fuel oil, lubricating oil, other liquid fuels), and gaseous fuels (liquefied petroleum gas (LPG), petroleum hydrocarbon gas, liquefied natural gas (LNG), natural gas (except liquefied natural gas (LNG)), coke oven gas, blast furnace gas, converter gas, town gas, other gaseous fuels). Activities carried out in relation to the manufacture of a product may be activities that consume at least one of heat and steam.

[0041] Activities carried out in relation to the manufacture of products may be divided into a plurality of categories. The activity amount allocation information may indicate at least one of the plurality of categories in association with each of the plurality of measuring instruments 20. The derivation unit 214 may derive the GHG emissions of each activity carried out in relation to the manufacture of products for each type of product for each category. Activities consuming electricity, gas, oil, or water carried out in relation to the manufacture of products A to F may be divided into categories such as factory Y, a first base and a second base, a first manufacturing process, a second manufacturing process, and a third manufacturing process, and a manufacturing line 1, a manufacturing line 2, and a manufacturing line 3. For example, to derive the GHG emissions in the category of manufacturing line 1, the derivation unit 214 may derive the GHG emissions of the measuring instruments 20 included in manufacturing line 1. M01 , Measuring Instruments 20 M04 , Measuring Instruments 20 M06 , Measuring Instruments 20 M08 , Measuring Instruments 20 M11 , Measuring Instruments 20 M14 , Measuring Instruments 20 M15 and measuring instruments 20 M18 The derivation unit 214 multiplies each measurement value by each emission coefficient and sums up the derived GHG emission amounts.

M15 , Measuring Instruments 20 M16 , Measuring Instruments 20 M17 and measuring instruments 20 M18To derive GHG emissions for a category called factory Y, the derivation unit 214 sums up the GHG emissions derived by multiplying each measurement value of all measuring instruments included in factory Y by each emission coefficient. The activity amount allocation information tables shown in Figs. 3C and 3D include columns indicating the production line, base, factory, organization, supply point, and power receiving point as category information. Of course, the category examples here are merely examples, and various other categories may be included in the activity amount allocation information tables depending on implementation needs.

[0042] The activities carried out in relation to the manufacture of the product may be divided into a plurality of sections, for example, (1) the unit of the manufacturing line of the product, (2) the unit of the facility where the product is manufactured, (3) the unit of the organization where the product is manufactured, (4) the unit of the supply point or the receiving point of the electricity consumed by the manufacturing device 10 used in the manufacture of the product, or (5) the unit of the supply chain of the product. As for (1), the derivation unit 214 derives the GHG emissions in the section called the manufacturing line 1 as described above. That is, the derivation unit 214 may derive the GHG emissions based on the activities that consume electricity, gas, oil, or water carried out in relation to the manufacture of the product in the section called each manufacturing line of the product. As for (2), the derivation unit 214 derives the GHG emissions in the section called the factory Y as described above. That is, the derivation unit 214 may derive the GHG emissions based on the activities carried out in relation to the manufacture of the product in the section called the facility such as the factory Y. As for (3), the derivation unit 214 may derive the GHG emissions based on the activities carried out in relation to the manufacture of the product in the section called the organization X. For example, if organization X has factory Z and business establishments A and B in addition to factory Y, the derivation unit 214 may derive the GHG emissions based on the activities carried out in relation to the production of products at the unit of organization X, which includes factories Y and Z and business establishments A and B.

[0043] Regarding (4), the activity amount allocation information table shown in FIG. 3C and FIG. 3D includes columns indicating a supply point and a power receiving point, and these columns include 22-digit numbers. The supply point number is a 22-digit number for identifying the location where electricity is used. The power receiving point number is a 22-digit number for identifying the location of a renewable energy (such as solar power) power generation facility. For example, the meter 20 M01 , Measuring Instruments 20 M02 , Measuring Instruments 20 M03 , Measuring Instruments 20 M04 , Measuring Instruments 20 M06 , Measuring Instruments 20 M08 , Measuring Instruments 20 M11 and measuring instruments 20 M14 In other words, the derivation unit 214 may assign one supply point number "xx-xxx-xxx-xxx-xxx-xxx-xxx-xxx-xxx" to the measuring device 20. M01 , Measuring Instruments 20 M02 , Measuring Instruments 20 M03 , Measuring Instruments 20 M04 , Measuring Instruments 20 M06 , Measuring Instruments 20 M08 , Measuring Instruments 20 M11 and measuring instruments 20 M14 For each unit, GHG emissions based on activities that consume electricity, gas, oil or water carried out in connection with the manufacture of a product may be derived.

[0044] Regarding (5), the derivation unit 214 may derive GHG emissions based on activities that consume electricity, gas, oil, or water carried out in relation to the manufacture of a product, at the unit of the supply chain of the manufacture of the product. The supply chain includes other organizations related to the activities of organization X. For example, if organizations A and B are included in the supply chain of products A to F of organization X, then by distributing the GHG emission derivation device 200 according to this embodiment in organizations A and B as well, it is possible to derive GHG emissions at the unit of the supply chain, making it easier to calculate GHG emissions, particularly in Scope 3.

[0045] The activity performed in relation to the manufacture of the product may be an activity using electricity. The acquisition unit 212 may further acquire electricity usage information indicating the usage of electricity in the specific category. The derivation unit 214 may derive the total GHG emission amount in the specific category based on the usage of electricity indicated in the electricity usage information. The derivation unit 214 may derive the direct GHG emission amount in the specific category from the activity amount measured by each measuring device 20 belonging to the specific category based on the activity amount allocation information. The derivation unit 214 may derive the indirect GHG emission amount in the specific category due to the use of electricity associated with the activity not measured by the multiple measuring devices 20 by subtracting the direct GHG emission amount from the total GHG emission amount. The derivation unit 214 may derive the indirect GHG emission amount in the specific category of the specific type of product by multiplying the indirect GHG emission amount by a ratio determined in advance for the specific type of product. The derivation unit 214 may derive the total GHG emissions in a specific category of a specific type of product by adding the indirect GHG emissions in the specific category of a specific type of product to the direct GHG emissions in the specific category of a specific type of product based on the activity amount allocation information.

[0046] Specifically, the acquiring unit 212 may acquire electricity usage information indicating the amount of electricity usage at the first location stored in the storage unit 220. For example, the electricity usage information is the amount of electricity usage shown on a monthly electricity receipt. Here, the amount of electricity usage shown on the electricity receipt for a certain month at the first location is 10,000 kWh. The acquiring unit 212 acquires 10,000 kWh as the electricity usage information for a certain month at the first location.

[0047] Next, the derivation unit 214 derives the total GHG emissions of the first location, which is a specific category, based on the electricity usage of 10,000 kWh indicated in the electricity usage information. In this specification, the total GHG emissions refers to the GHG emissions that are a combination of direct GHG emissions and indirect GHG emissions, which will be described later. The derivation unit 214 multiplies the electricity usage of 10,000 kWh by the electricity emission coefficient of 0.441 (kg-CO2 / kWh) to derive the total GHG emissions 4410 (kg-CO2) of the first location. Next, the derivation unit 214 refers to the activity amount allocation information table and determines whether the measuring device 20 that measures electricity usage at the first location is M01 , Measuring Instruments 20 M02 , Measuring Instruments 20 M03 , Measuring Instruments 20 M04 , Measuring Instruments 20 M06 , Measuring Instruments 20 M08 , Measuring Instruments 20 M11 and measuring instruments 20 M14 The derivation unit 214 determines whether the measurement device 20 in the certain month stored in the storage unit 220 is M01 , Measuring Instruments 20 M02 , Measuring Instruments 20 M03 , Measuring Instruments 20 M04 , Measuring Instruments 20 M06 , Measuring Instruments 20 M08 , Measuring Instruments 20 M11 and measuring instruments 20 M14 The derivation unit 214 determines the amount of electricity usage measured by each of the measuring instruments 20 and sums up the respective values. The total value is 8,000 kWh. The derivation unit 214 multiplies the total amount of electricity usage, 8,000 kWh, by the electricity emission coefficient 0.441 (kg-CO2 / kWh) to derive the amount of direct GHG emissions emitted for the manufacture of products for that certain month at the first site. In this specification, the amount of GHG emissions emitted for the manufacture of products and directly derived from the amount of usage measured by the measuring instrument 20 is referred to as direct GHG emissions. The derivation unit 214 multiplies 8000 (kWh) by 0.441 (kg-CO2 / kWh) to derive the amount of direct GHG emissions at the first site, 3528 (kg-CO2).

[0048] Next, the derivation unit 214 subtracts the direct GHG emissions 3528 (kg-CO2) of the first site from the total GHG emissions 4410 (kg-CO2) of the first site to derive indirect GHG emissions 882 (kg-CO2). In this specification, indirect GHG emissions refer to GHG emissions due to the use of electricity associated with activities that are not subject to measurement by a measuring device. Examples of indirect GHG emissions include GHG emissions due to the use of electricity in places where products are not directly manufactured, such as break rooms, offices, and toilets at the first site.

[0049] Next, the derivation unit 214 derives the indirect GHG emission amount 176.4 (kg-CO2) of the product A at the first base by multiplying the indirect emission amount 882 (kg-CO2) by a predetermined ratio for the specific type of product. The predetermined ratio may be determined based on, for example, the number of products sold or the number of products produced. Here, the predetermined ratios are 20%, 20%, 20%, 15%, 15%, and 10% for product A, product B, product C, product D, product E, and product F, respectively. The derivation unit 214 multiplies the indirect GHG emission amount 882 (kg-CO2) by 0.2 to derive the indirect GHG emission amount 176.4 (kg-CO2) of the product A at the first base. The predetermined ratio may be recorded in the activity amount allocation information table.

[0050] Next, the derivation unit 214 derives the direct GHG emission amount of the product A at the first site based on the activity amount allocation information table. The derivation unit 214 refers to the activity amount allocation information table and determines that the measuring device that measures the electricity usage related to the production of the product A at the first site is the measuring device 20. M01 , Measuring Instruments 20 M04 , Measuring Instruments 20 M06 , Measuring Instruments 20 M08 , Measuring Instruments 20 M11 and measuring instruments 20 M14 The derivation unit 214 determines whether the measurement device 20 M01 , Measuring Instruments 20 M04 , Measuring Instruments 20 M06 , Measuring Instruments 20 M08 , Measuring Instruments 20 M11 and measuring instruments 20 M14The electricity usage measured by each of the measuring devices for the given month is identified and the respective values ​​are summed up. The total value is 6,000 kWh. The ratio of product A to all of these measuring devices is 40%. Therefore, the derivation unit 214 multiplies 6000 kWh by the emission coefficient 0.441 (kg-CO2 / kWh) and the ratio 40% to derive the direct GHG emission amount of product A at the first site of 1058.4 (kg-CO2). After that, the derivation unit 214 adds the derived indirect GHG emission amount of product A at the first site of 176.4 (kg-CO2) to the direct GHG emission amount of product A at the first site of 1058.4 (kg-CO2), to derive the total GHG emission amount of product A at the first site of 1234.8 (kg-CO2).

[0051] According to this embodiment, the activity amount allocation information table includes a plurality of categories, and GHG emissions can be derived for each category, and GHG emissions can be calculated in various units. In addition, direct GHG emissions and indirect GHG emissions for a specific product in a specific category can be derived by the ratio of each product to the measuring device and the predetermined ratio of a specific product to indirect GHG emissions, and further, the overall GHG emissions for a specific product in a specific category can be derived. Furthermore, by introducing the GHG emission derivation device according to this embodiment into a supply chain, it becomes easy to calculate GHG emissions in the supply chain. Furthermore, the type of product, the ratio of activity amount allocated to the product, and the emission coefficient shown in the activity amount allocation information table can be appropriately changed via the change receiving unit 216. Therefore, even if the type of product manufactured in the product line, the ratio of the product, etc., is changed, it is only necessary to modify the contents shown in the activity amount allocation information table.

[0052] FIG. 4 is a flow diagram for deriving GHG emissions from each activity carried out in relation to the manufacture of each product type according to the present embodiment.

[0053] In S100, the acquisition unit 212 acquires the amount of electricity, gas, oil, or water used in the production of at least one type of product from the multiple measuring instruments 20. For example, when deriving the amount of GHG emissions due to activities performed in the production of product A, the acquisition unit 212 acquires the measurement value data stored in the storage unit 220. For example, the acquisition unit 212 acquires the amount of electricity, gas, oil, or water used in the production of product A based on the measurement value data for a certain month. M01 , Measuring Instruments 20 M04 , Measuring Instruments 20 M06 , Measuring Instruments 20 M08 , Measuring Instruments 20 M11 , Measuring Instruments 20 M14 , Measuring Instruments 20 M15 and measuring instruments 20 M18 Obtain the measured amount of electricity usage.

[0054] In S102, the derivation unit 214 multiplies the acquired electricity, gas, oil, or water usage by each emission coefficient and the product ratio based on the activity amount allocation information indicating the type of product and the ratio of the activity amount allocated to the product. M01 , Measuring Instruments 20 M04 , Measuring Instruments 20 M06 , Measuring Instruments 20 M08 , Measuring Instruments 20 M11 , Measuring Instruments 20 M14 , Measuring Instruments 20 M15 and measuring instruments 20 M18 The derivation unit 214 multiplies the obtained amount of electricity usage by the emission coefficient and the proportion of product A.

[0055] In S104, the derivation unit 214 derives the value resulting from the multiplication as the amount of GHG emissions due to activities consuming electricity, gas, oil, or water carried out in relation to the production of the product. The derivation unit 214 derives the value resulting from the multiplication as the amount of GHG emissions due to activities consuming electricity carried out in relation to the production of product A. The flow ends.

[0057] In S200, the acquisition unit 212 acquires the amount of electricity usage for a specific category. For example, the acquisition unit 212 acquires 10,000 kWh as the amount of electricity usage for a certain month at the first location stored in the storage unit 220.

[0058] In S202, the derivation unit 214 derives the total GHG emission amount for the specific category by multiplying the electricity usage amount acquired by the acquisition unit 212 by the emission coefficient.

[0059] In S204, the derivation unit 214 derives the direct GHG emission amount for the specific category by multiplying the amount of electricity usage measured by each measuring device 20 belonging to the specific category by an emission coefficient based on the activity amount allocation information table. Specifically, the derivation unit 214 refers to the activity amount allocation information table stored in the storage unit 220 and derives the amount of direct GHG emission for the specific category by multiplying the amount of electricity usage measured by each measuring device 20 belonging to the first location by an emission coefficient. M01 , Measuring Instruments 20 M02 , Measuring Instruments 20 M03 , Measuring Instruments 20 M04 , Measuring Instruments 20 M06 , Measuring Instruments 20 M08 , Measuring Instruments 20 M11 and measuring instruments 20 M14 The derivation unit 214 determines whether the measurement device 20 is a M01 , Measuring Instruments 20 M02 , Measuring Instruments 20 M03 , Measuring Instruments 20 M04 , Measuring Instruments 20 M06 , Measuring Instruments 20 M08 , Measuring Instruments 20 M11 and measuring instruments 20 M14The derivation unit 214 identifies the amount of electricity usage measured by each of the first and second bases and sums up the respective values. The total value is 8,000 kWh. The derivation unit 214 multiplies the total amount of electricity usage, 8,000 kWh, by the electricity emission coefficient 0.441 (kg-CO2 / kWh) to derive the amount of GHG emissions emitted for the manufacture of products for that certain month at the first base, i.e., the amount of direct GHG emissions. The derivation unit 214 multiplies 8,000 (kWh) by 0.441 (kg-CO2 / kWh) to derive the amount of direct GHG emissions from the first base, 3528 (kg-CO2).

[0060] In S206, the derivation unit 214 subtracts the direct GHG emission amount of the specific section from the total GHG emission amount of the specific section to derive the indirect GHG emission amount of the specific section. The derivation unit 214 subtracts the direct GHG emission amount of the first site of 3528 (kg-CO2) from the total GHG emission amount of the first site of 4410 (kg-CO2) to derive the indirect GHG emission amount of the first site of 882 (kg-CO2).

[0061] In S208, the derivation unit 214 multiplies the indirect GHG emissions by a predetermined ratio for a specific type of product to derive the indirect GHG emissions in a specific category of a specific product. The predetermined ratio for product A is assumed to be 20%. The derivation unit 214 multiplies the indirect GHG emissions of 882 (kg-CO2) at the first site derived in S206 by 0.2 to derive the indirect GHG emissions of 176.4 (kg-CO2) at the first site for product A.

First, the derivation unit 214 derives the direct GHG emissions of product A at the first site based on the activity amount allocation information table. The derivation unit 214 refers to the activity amount allocation information table and calculates that the measuring device 20 that measures the electricity usage related to the production of product A at the first site is the measuring device 20 M01 , Measuring Instruments 20 M04 , Measuring Instruments 20 M06, Measuring Instruments 20 M08 , Measuring Instruments 20 M11 and measuring instruments 20 M14 The derivation unit 214 determines whether the measurement device 20 M01 , Measuring Instruments 20 M04 , Measuring Instruments 20 M06 , Measuring Instruments 20 M08 , Measuring Instruments 20 M11 and measuring instruments 20 M14 The electricity usage measured by each of the devices in the given month is identified, and the respective values ​​are summed up. The total value is 6,000 kWh. The ratio of product A to these measuring devices is 40% for all of them. Therefore, the derivation unit 214 multiplies 6000 kWh by the emission coefficient 0.441 (kg-CO2 / kWh) and the product ratio of 40% to derive the direct GHG emission amount of product A at the first site of 1058.4 (kg-CO2). Next, the derivation unit 214 adds the indirect GHG emission amount of product A at the first site of 176.4 (kg-CO2) derived in S208 to the direct GHG emission amount of product A at the first site of 1058.4 (kg-CO2) to derive the total GHG emission amount of product A at the first site of 1234.8 (kg-CO2). The flow ends.
