[0016] 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.

[0017] 1 shows an example of the overall configuration of a GHG emission derivation system 10 according to this embodiment. The GHG emission derivation system 10 includes a derivation device 100, an X company database 200, and an emission intensity unit database 300. The derivation device 100 communicates with various databases such as the X company database 200 and the emission intensity unit database 300 via a network 50.

[0018] FIG. 2 shows an example of each part constituting the derivation device 100. The derivation device 100 has an acquisition unit 102, a derivation unit 104, a ratio reception unit 106, an emission coefficient reception unit 108, a presentation unit 110, and a production amount reception unit 112. The derivation device 100 according to the present embodiment may be a computer. The computer may have various memories such as a CPU, a ROM, a RAM, an EEPROM (registered trademark), a communication bus, and an interface, and may function as the derivation device 100 by having the CPU read and sequentially execute a processing program stored in the ROM as firmware in advance. Each part of the derivation device 100 may be configured by installing a program stored in a computer-readable recording medium and performing various processes for deriving GHG emissions, and having the computer execute this program. In other words, the derivation device 100 may be configured by having the computer execute a program for performing various processes for deriving GHG emissions, thereby causing the computer to function as each part of the derivation device 100.

[0019] In recent years, there have been attempts to grasp and manage the entire organizational activity by deriving supply chain emissions, which indicate GHG emissions of all supply chains related to business activities, rather than just the greenhouse gas emissions (GHG emissions) of the business itself. Supply chain emissions indicate GHG emissions generated by organizational activities throughout the entire series of flows, including raw material procurement, manufacturing, logistics, sales, and disposal. Supply chain emissions consist of Scope 1, Scope 2, and Scope 3.

[0020] Scope 1 refers to direct emissions, which indicate greenhouse gas emissions directly emitted by the business itself. Scope 2 refers to indirect emissions (indirect emissions from energy sources), which indicate greenhouse gas emissions indirectly emitted when a business purchases energy such as electricity, heat, steam, etc. from other companies such as electric power companies and uses the purchased energy. Scope 3 refers to other indirect emissions, which indicate greenhouse gas emissions emitted by activities in the business's supply chain that are not included in Scope 1 or Scope 2. Scope 3 is further divided into 15 categories depending on the activities.

[0021] Category 1 indicates "purchased products and services". Category 2 indicates "capital goods". Category 3 indicates "fuel and energy-related activities not included in Scope 1 and Scope 2". Category 4 indicates "upstream transportation and handling". Category 5 indicates "waste generated from business activities". Category 6 indicates "business trips". Category 7 indicates "employee commuting". Category 8 indicates "upstream leased assets". Category 9 indicates "downstream transportation and distribution". Category 10 indicates "processing of sold products". Category 11 indicates "use of sold products". Category 12 indicates "disposal of sold products". Category 13 indicates "downstream leased assets". Category 14 indicates "franchises". Category 15 indicates "investments". Scope 3 further includes "others" which indicate indirect GHG emissions not included in the 15 categories. GHG emissions that fall under "others" include, for example, GHG emissions related to the daily lives of employees or consumers.

[0022] Supply chain emissions are the sum of Scope 1 emissions, Scope 2 emissions, and Scope 3 emissions. Throughout Scope 1 to Scope 3, the basic formula is activity amount x emission intensity. For Scope 3 emissions, the basic formula is derived for each of the 15 categories and then summed up to derive. The activity amount in the basic formula is the amount related to the scale of the business's activities. For example, the amount of electricity used, the amount of cargo transported, the amount of waste processed, and various transaction amounts are applicable. Activity amounts are collected from various data within the organization regarding products or services, literature data, industry average data, design values, etc. Emission intensity is the amount of GHG emissions per activity amount. For example, GHG emissions per kWh of electricity used, GHG emissions per ton-kilometer of cargo transported, and GHG emissions per ton of waste incinerated are applicable. Basically, emission intensity is selected from an existing database and used, but there are also methods of directly measuring emissions or receiving the results of emissions derivation from business partners.

[0023] Meanwhile, particularly in the manufacturing industry, a major challenge is how to calculate GHG emissions for each product in-house and provide the recipient with the GHG emission coefficient (also known as the carbon footprint (cradle-to-grave)) per product.

[0024] Therefore, in this embodiment, a derivation device, a derivation method, and a program are provided that can calculate the GHG emission amount for each product and derive the GHG emission coefficient for each product. In this embodiment, the product includes a service. In this embodiment, the organization is not limited to a company, but broadly includes private businesses, government agencies, local governments, schools, associations, groups, etc.

[0025] 3A, 3B, 3C, 3D, and 3E show GHG emission information showing greenhouse gas emissions (GHG emissions) for each activity of an organization. The GHG emission information shown in FIG. 3A is a table created by combining the tables in FIG. 3B to FIG. 3E, which are stored in association with each other in the X Company database 200. From this, the total GHG emissions from April 1, 2021 to March 31, 2022 for product A, which is one of X Company's products, are to be derived. First, information about product A is registered.

[0026] FIG. 4 shows a screen for registering product information. Enter "Product A" in the Product Name box B10. In the Finished Product / Intermediate Product box B12, select "Intermediate Product" from the pull-down menu. In the Processing Location box B14, select "Factory Y" from the pull-down menu. In the Delivery Destination Processing Location box B24, select "Factory Z" from the pull-down menu. Enter the electricity supply point identification number in the Supply Point Identification Number box B16. Enter the electricity supply point identification number of the delivery destination in the Delivery Destination Supply Point Identification Number box B26. Enter "1000000" in the Production Quantity box B18 and Sales Quantity box B20. For the Production Year B22, select "2021" from the pull-down menu. The screen in FIG. 4 is only an example, and more or less items may be included.

[0027] The acquisition unit 102 acquires GHG emissions for each activity of the organization related to the product from GHG emission information indicating GHG emissions for each activity of the organization based on activity information indicating the activity of the organization related to the product provided by the organization.

[0028] The acquisition unit 102 queries the GHG emission information in FIG. 3A for the period from April 1, 2021 to March 31, 2022 and for the "Notes" column C1 containing "Common" or "Product A", and extracts all relevant rows. "Common" in the "Notes" column indicates that the relevant row is data that applies not only to Product A, but to multiple products in common. "Product A" in the "Notes" column indicates that the relevant row is data that applies only to Product A.

[0029] FIG. 5 shows the information extracted as a result of the above inquiry. The entire table displayed in FIG. 5 is activity information showing the organization's activities related to the products provided by the organization. Each row in the table is the GHG emissions for each activity of the organization related to the product. Note that in this explanation, the relevant rows are extracted by specifying conditions, but this is merely an example. For example, the GHG emissions information shown in FIG. 3A does not need to include the "Notes" column. In this case, the user may directly select the desired row to extract activity information.

[0030] The derivation unit 104 derives the total GHG emissions related to the product based on the GHG emissions for each activity of the organization related to the product acquired by the acquisition unit 102. A calculation formula is set in advance in the SUM (GHG emissions) field F10 in FIG. 5, and a value obtained by summing all values ​​included in the GHG emissions column in FIG. 5 is displayed. The derivation unit 104 multiplies the value 812300.5 displayed in the SUM (GHG emissions) field F10 by a predetermined coefficient for product A. The predetermined coefficient may be a coefficient predetermined for each product. For example, the predetermined coefficient may be a ratio to the sales amount of the product, a ratio of the number of products sold by the organization, or the like. The products handled by company X are, for example, two products, product A and product B. Therefore, the derivation unit 104 may multiply 812300.5 by a predetermined coefficient 0.5 for product A to derive 406150.25. As a result, the total GHG emissions related to product A are derived as 406150.25.

[0031] The acquisition unit 102 acquires GHG emissions for each activity of an organization related to a product for each predetermined period, and the derivation unit derives the total GHG emissions for each predetermined period. In the above description, the period is specified as from April 1, 2021 to March 31, 2022. In this manner, in this embodiment, activity information indicating the activity of an organization can be acquired by specifying a period.

[0032] Alternatively or in addition, the derivation device 100 may further include a ratio receiving unit 106 that receives each ratio to be assigned as GHG emissions related to the product with respect to the GHG emissions for each activity content of the organization related to the product. FIG. 6 is a diagram showing a screen for assigning ratios to GHG emissions. Referring to FIG. 6, a "ratio" column C10 and a "multiplied GHG emissions" column C12 are further added to the table shown in FIG. 5. The value entered in the "ratio" column C10 is accepted by the ratio receiving unit 106. The electricity usage in the first row, the gasoline usage in the second row, the screw purchase in the third row, and the business trip in the fourth row in the table of FIG. 6 are data that apply not only to product A but also to multiple products of company X, since they are indicated as "common" in the "remarks" column. Therefore, the ratio of product A to these "common" data is specified. The ratio of product A to electricity usage on April 1, 2021 is 50%. Therefore, the ratio receiving unit 106 accepts the designation of "50%" by the user. Similarly, the ratio receiving unit 106 also receives ratio designations for gasoline usage, screw purchases, and business trips. For the purchase of packaging materials for product A and delivery of product A, no ratio is designated since these data are applied only to product A. When the user finishes designating the ratio and clicks the ratio registration button D1, the values ​​obtained by multiplying each value in the "GHG emission amount" column C14 by each value in the "ratio" column C10 are automatically displayed in the "multiplied GHG emission amount" column C14 adjacent to the "ratio" column C10. For the purchase of packaging materials for product A and delivery of product A for which no ratio is designated, clicking the ratio registration button D1 automatically inputs 100% into the "ratio" column C10 and copies the value in the "GHG emission amount" column C14 into the "multiplied GHG emission amount" column C12.

[0033] The derivation unit 104 multiplies the GHG emission amount for each activity of the organization related to the product by each ratio, and sums up each of the multiplied GHG emission amounts to derive the total GHG emission amount. A calculation formula is set in advance in the SUM (multiplied GHG emission amount) field F12 in FIG. 6, and when the ratio registration button D1 is clicked, a value obtained by summing up all values ​​included in the "multiplied GHG emission amount" column C12 is displayed. The derivation unit 104 derives the total GHG emission amount of product A by reading the value of the SUM (multiplied GHG emission amount) field F12. The ratio may be determined in advance. For example, the ratio may be determined in advance based on the ratio of the number of products produced, the ratio of production time, etc. Alternatively, the derivation unit 104 may be designed to accept the designation of an actual measured value instead of the ratio. As described later, the total GHG emission amount of product A derived here does not include the GHG emission amounts of the processing of the sold product (category 10), the use of the sold product (category 11), and the disposal of the sold product (category 12).

[0034] The GHG emissions for each activity of the organization include direct emissions, which indicate GHG emissions directly emitted by the organization, indirect emissions, which indicate GHG emissions indirectly emitted by the organization through the purchase of energy, and other indirect emissions, which indicate GHG emissions emitted by the organization's activities not included in direct emissions and indirect emissions. In the table shown in Figure 6, the gasoline consumption in the second row corresponds to Scope 1, that is, direct emissions, which indicate GHG emissions directly emitted by the organization. The electricity consumption in the first row corresponds to Scope 2, that is, indirect emissions, which indicate GHG emissions indirectly emitted by the organization through the purchase of energy. The purchase of screws in the third row, business trips in the fourth row, purchase of packaging materials for product A in the fifth row, and delivery of product A in the last row correspond to Scope 3, that is, other indirect emissions, which indicate GHG emissions emitted by the organization's activities not included in direct emissions and indirect emissions.

[0035] The activity information does not indicate the processing, use, and disposal of products as the activity content of the organization, and the derivation device 100 further includes an emission coefficient receiving unit 108 that receives an emission coefficient of at least one GHG emission of the processing, use, and disposal of the product and an activity amount corresponding to the emission coefficient. The derivation unit 104 derives the total GHG emission based on the GHG emission for each activity content of the organization acquired by the acquisition unit 102 and the emission coefficient and activity amount of at least one GHG emission. The activity information in FIG. 6 does not include each GHG emission of the processing of sold products (category 10), the use of sold products (category 11), and the disposal of sold products (category 12). The reason is that for categories 10, 11, and 12, the subject is not the organization X company, but the purchaser of the product. Therefore, each GHG emission of the processing, use, and disposal of the product needs to be derived separately. In deriving GHG emissions from processing, use, and disposal, it is desirable to have the recipient set up scenarios for processing, use, and disposal and provide emission factors and activity data associated with processing, use, and disposal. Acquisition of emission factors and activity data from the recipient may be done by blockchain.

[0036] 7 shows a screen for accepting emission coefficients and activity amounts related to the processing, use, and disposal of a product, which is an example of a screen for inputting emission coefficients accepted by the emission coefficient accepting unit 108. Here, according to the information registered in FIG. 4, it is assumed that Product A is a personal computer, and the number of units sold in fiscal year 2021 is 1 million. The personal computer in this explanation is an intermediate product in which the manufacturer pre-installs an OS and other applications when delivered to the manufacturer.

[0037] First, derive the GHG emissions related to the processing of sold products of category 10. In the scenario of processing a computer, it is assumed that it takes one hour for the delivery manufacturer to install the program per computer. The power consumption per hour is 0.1 kWh, and the emission coefficient is 0.0004530 (t-CO2 / kWh). Therefore, in the "Specify the emission coefficient and activity amount for the processing of sold products" area, enter "0.1 (kWh) x 1 (h) x 1,000,000 (units)" in the "Activity amount" field F20. Enter "0.0004530 (t-CO2 / kWh)" in the "Emission coefficient" field F22. Then, "45.3" is displayed in the "GHG emissions (processing)" field F24, where the calculation formula is set. Note that the explanation here is merely an example, and it is also possible to enter the sales amount as the activity amount and the CO2 equivalent per unit sold as the emission coefficient. Alternatively, the number of sales may be input as the amount of activity, and the amount of electricity used x time may be input as the emission coefficient. As long as the amount of GHG emissions related to the processing of the sold products can be derived, the present embodiment is not limited in this respect.

[0038] Next, derive the GHG emissions related to the use of sold products. Category 11 GHG emissions are calculated by multiplying the number of sales in the reporting year by the lifetime emissions. For the scenario of using a PC, the specifications indicate that the annual power consumption is 1350 kWh and the average useful life is 5 years. The emission factor is set to 0.0004530 (t-CO2 / kWh), the same as for processing. Therefore, in the "Specify the emission factor and activity amount related to the use of sold products" area, enter "1350 (kWh) x 5 (years) x 1,000,000 (units)" in the "Activity amount" field F26. Enter "0.0004530 (t-CO2 / kWh)" in the "Emission factor" field F28. Then, "3057750" is displayed in the "GHG emissions (use)" field F30, where the calculation formula is set. The explanation here is merely an example, and it is also possible to input the sales amount as the amount of activity and the CO2 equivalent per unit sold as the emission coefficient. Alternatively, it is also possible to input the number of sales as the amount of activity and the amount of electricity used x time as the emission coefficient. As long as it is possible to derive the GHG emissions related to the use of the sold products, the present embodiment is not limited in this respect.

[0039] Next, derive the GHG emissions relating to the disposal of sold products. In the scenario for disposal of a PC, the PC is an integrated PC body and display with an estimated weight of 8.09 kg, and will be recycled with transportation. In this case, the emission coefficient per unit is 0.000521 (t-CO2 / unit). Therefore, in the "Specify emission coefficient and activity amount relating to disposal of sold products" area, enter "1,000,000 (units)" in the "Activity amount" field F32. Enter "0.000521 (t-CO2 / unit)" in the "Emission coefficient" field F34. Then, "521" is displayed in the "GHG emissions (disposal)" field F36, for which a calculation formula has been set.

[0040] The SUM (processing, use, disposal) field F40 is located in the area indicated as B1 in Figure 7. A formula is set in the SUM (processing, use, disposal) field F40, and the total value of 65798.3, obtained by adding up the values ​​in the "GHG emissions (processing)" field F24, the "GHG emissions (use)" field F30, and the "GHG emissions (disposal)" field F36, is automatically displayed.

[0041] The area indicated as C1 in FIG. 7 is provided with a SUM(A1+B1) field F42. The SUM(A1+B1) field F42 is input with a value obtained by adding the value of the SUM(multiplied GHG emission amount) indicated in the A1 area in FIG. 6 to the value of the SUM(processing, use, disposal) field F40, "65798.3". Here, the multiplied GHG emission amount indicated in the A1 area in FIG. 6 is assumed to be 453215. The derivation unit 104 reads the value 519013.3 indicated in the SUM(A1+B1) field F42, and derives the total GHG emission amount based on the GHG emission amount for each activity content of the organization acquired by the acquisition unit 102 and the emission coefficient and activity amount of at least one GHG emission amount. Note that the above explanation is given for the case where the product A is an intermediate product. If the product A is a finished product, the display in FIG. 7 does not need to include the "Specify the emission coefficient and activity amount related to the processing of the sold product" area.

[0042] In summary, when the product is a finished product that does not require processing, the emission coefficient receiving unit 108 receives each emission coefficient for the use and disposal of the product and each activity amount corresponding to the each emission coefficient, and the derivation unit 104 derives the total GHG emission amount based on the GHG emission amount for each activity content of the organization acquired by the acquisition unit 102, each emission coefficient, and each of the activity amounts. On the other hand, when the product is an intermediate product that requires processing, the emission coefficient receiving unit 108 receives each emission coefficient for the processing, use, and disposal of the product and each activity amount corresponding to the each emission coefficient, and the derivation unit 104 derives the total GHG emission amount based on the GHG emission amount for each activity content of the organization acquired by the acquisition unit 102, each emission coefficient, and each of the activity amounts.

[0043] In addition, when the designation of the emission factor is accepted in each of the "emission factor" columns for the processing, use, and disposal of the product, at least one emission factor may be presented. Specifically, the derivation device 100 further includes a presentation unit 110 that presents at least one emission factor, and the emission factor reception unit 108 accepts an emission factor selected from the at least one emission factor presented by the presentation unit 110 as the emission factor. FIG. 8A shows an example of a screen displaying the emission factor presented by the presentation unit 110. When the presentation unit 110 presents at least one emission factor, the presentation unit 110 may present the emission factor from the emission intensity database 300 in FIG. 1. In the emission intensity database 300, the emission factor may be stored in association with, for example, information of a power company. As shown in FIG. 8A, when a unit is selected from the pull-down menu of the "unit" column C22, the presentation unit 110 may present a list of appropriate emission factors in the "emission factor" column C20. When a specific emission coefficient is selected from the list, the emission coefficient receiving unit 108 receives the selected emission coefficient as the emission coefficient.

[0044] Furthermore, the presentation unit 110 presents, as at least one emission coefficient, a plurality of emission coefficients selected from the emission coefficients previously assigned to each location in order of proximity to the location where the product is used, disposed of, or processed. The location assigned to each emission coefficient may be the installation location of the power generation facility. The presentation unit 110 may refer to the processing location of the delivery destination registered in the delivery destination processing location box B24 on the screen shown in FIG. 4, and display the processing location on the input screen for the emission coefficient received by the emission coefficient reception unit 108, as shown in FIG. 8B. When the unit of electricity is specified in the pull-down of the "Unit" column C30, the presentation unit 110 may present, in the "Emission coefficient" column C32, a list of emission coefficients of power supply companies close to the processing location Z factory in order of proximity.

[0045] Furthermore, the presentation unit 110 may present, as at least one emission coefficient, a plurality of emission coefficients selected from the emission coefficients previously assigned to each location in order of proximity to the location where the product is used, disposed of, or processed, in ascending order of value. For example, if there are a plurality of power supply companies in the same region, they may be presented in ascending order of emission coefficient, as shown in FIG. 8B.

[0046] Instead of the processing location, the presentation unit 110 may refer to the supply point identification number. In this case, the presentation unit 110 may present a list of emission factors of power supply companies that are close to the point identified by the supply point identification number in order of proximity. If there are multiple power supply companies near the point identified by the supply point identification number, the emission factors may be further sorted and presented in ascending order of emission factors. In addition, when presenting the emission factor, the average emission factor of the entire power system in the area where the organization is active may be presented based on the location criteria. In addition, the emission factor to be presented may be specified according to a learning model trained using teacher data in which the amount of activity is input and the emission factor is output. Furthermore, the emission factors may be presented in order of high usage rate based on the industry of the organization.

[0047] Refer back to Figure 7. Up to this point, the total value of GHG emissions from product A by organization X after multiplying the ratio of product A and GHG emissions from the processing, use, and disposal of sold product A has been derived in the SUM(A1+B1) field F42 shown in C1. From this, we will derive the GHG emission factor as the carbon footprint per unit of product A.

[0048] The derivation device 100 further includes a production volume receiving unit 112 that receives the production volume of the product, and the derivation unit 104 derives an emission coefficient of the product indicating the GHG emission per product based on the total GHG emission and the production volume. FIG. 9 shows a screen for calculating the emission coefficient per product A, which is an example of an input screen for the production volume received by the production volume receiving unit 112. The value 519013.3 displayed in the SUM(A1+B1) field F42 indicated as C1 in FIG. 7 is copied to the "C1(A1+B1)" column C40 in FIG. 9. The registered production volume of 1000000 shown in FIG. 4 is copied to the "production volume" column C42. When it is confirmed that these values ​​are correct, the user clicks the execute button D2. As a result, 0.5190133 is displayed in the "C÷production volume=GHG emission per product" column C44. The derivation unit 104 derives the emission coefficient of product A, which indicates the GHG emission per product A, by reading the value 0.5190133 displayed in the column C44 "C÷production number=GHG emission per product". In the above explanation, the emission coefficient per product A was derived by dividing the sum of the GHG emission of product A after the ratio multiplication in the A1 field and the GHG emission of product A related to processing, use, and disposal in the B1 field by the production number. In addition, the emission coefficient per product A may be derived by dividing the GHG emission of product A after the ratio multiplication in the A1 field by the production number and the GHG emission of product A related to processing, use, and disposal in the B1 field by the production number. In addition, the GHG emission reduction contribution for a comparison product (old product, etc.) may be calculated. For this purpose, for example, the difference between the GHG emission per product of the comparison product and the GHG emission per product of A may be multiplied by the penetration amount of product A. Furthermore, the carbon tax may be derived using the derived GHG emission amount per product A and displayed according to a format such as financial information.

[0049] FIG. 10 shows a flow for deriving the total GHG emission amount of a product by the deriving device 100 according to this embodiment.

[0050] In S100, the acquisition unit 102 acquires product information registered by a user.

[0051] In S102, the acquisition unit 102 acquires a condition specification for inquiring about GHG emission information indicating GHG emission amounts for each activity of the organization. In this embodiment, the conditions specified are that the period is from April 1, 2021 to March 31, 2022, and the remarks column is "common" or "A product". However, as described above, instead of specifying a condition, the user may directly select a row of desired activity information from the GHG emission information. In that case, S102 is omitted.

[0052] In S104, the acquisition unit 102 extracts all rows that match the specified conditions from the GHG emission information and acquires them as activity information that indicates the activity content of the organization related to the product. If the user directly selects the desired row instead of specifying the conditions, the acquisition unit S104 acquires the activity information that indicates the activity content of the organization related to the product through the selection.

[0053] In S106, it is determined whether or not a ratio is specified.

[0054] If the ratio is not specified, the process proceeds to S110. In S110, the derivation unit 104 sums up all the values ​​included in the "GHG emission amount" column in the activity information.

[0055] In S112, the derivation unit 104 multiplies the total value by a predetermined coefficient of the product.

[0056] In S114, the derivation unit 104 multiplies the total value by a predetermined coefficient to derive the total GHG emission amount related to the product. The flow ends.

[0057] If a ratio is to be specified, proceed to S106. The ratio receiving unit 106 receives the ratio for the common information specified in the "Ratio" column C10. Clicking the ratio registration button D1 triggers the derivation unit 104 to multiply the value in the "GHG emission amount" column C14 by the ratio, and derives the GHG emission amount after multiplication in the "GHG emission amount after multiplication" column C12.

[0058] In S108, the derivation unit 104 sums up all the values ​​included in the "multiplied GHG emission amount" column C12. The derivation unit 104 derives the sum as the total GHG emission amount related to the product. The flow ends.

[0059] FIG. 11 is a flow chart showing a process for deriving a product emission coefficient indicating the amount of GHG emission per product by the deriving device 100 according to the present embodiment.

[0060] In S200, the emission coefficient receiving unit 108 refers to the registered product information and determines whether the product is a finished product or an intermediate product.

[0061] If the product is an intermediate product, the process proceeds to S202. The emission coefficient receiving unit 108 receives each emission coefficient for the processing, use, and disposal of the product, and each activity amount corresponding to each emission coefficient.

[0062] In S204, the derivation unit 104 sums up the GHG emissions from processing, use, and disposal.

[0063] In S206, the derivation unit 104 adds the GHG emission amount of the processing, use, and disposal to the total GHG emission amount of the product that has been derived other than the processing, use, and disposal.

[0064] In S214, the derivation unit 104 divides the GHG emission amount after the addition by the number of products produced.

[0065] In S216, the derivation unit 104 derives a value obtained by dividing the added GHG emission amount by the number of products produced as a GHG emission coefficient per product. The flow then ends.

[0066] If the product is a finished product, the process proceeds to S208. The emission coefficient receiving unit 108 receives each emission coefficient for the use and disposal of the product and each activity amount corresponding to each emission coefficient.

[0067] In S210, the derivation unit 104 sums up the GHG emissions from use and disposal.

[0068] In S212, the derivation unit 104 adds the amount of GHG emission from use and disposal to the total amount of GHG emission from the product other than use and disposal that has already been derived.

[0069] In S214, the derivation unit 104 divides the GHG emission amount after the addition by the number of products produced.

[0070] In S216, the derivation unit 104 derives a value obtained by dividing the added GHG emission amount by the number of products produced as a GHG emission coefficient per product. The flow then ends.

[0071] As described above, according to the present embodiment, the GHG emission amount for each product is derived using the supply chain emission amount, and the GHG emission coefficient per product can be efficiently derived. Since the existing supply chain emission amount can be used, the processing load and the increase in memory capacity of the derivation device 100 can be suppressed. The GHG emission coefficient per product can be derived more accurately by deriving each GHG emission amount of the processing, use, and disposal of the product from the emission coefficient and activity amount that are separately accepted without using the supply chain emission amount of the organization. In the present embodiment, at least one of the activity amount, emission coefficient, and GHG emission amount of the organization of X company is linked to the product of X company. However, in other embodiments, at least one of the activity amount, emission coefficient, and GHG emission amount of another organization such as Y company may be linked to the product of X company instead. For example, the GHG emission amount of X company in Scope 3 Category 1 may be calculated from the activity amount and emission coefficient of the organization of Y company inputted by Y company (separate account) through this system. Then, the product of X company may be linked to the GHG emission amount derived based on the input of Y company.

[0072] As another example, the emission factor associated with the product of Company A (e.g., wholesaler) may be the emission factor for the processing of the product set by Company B (e.g., manufacturer) through this system. In the above other embodiment, which of the activity amount, emission factor, and GHG emission amount associated with the product of Company X is disclosed to Company X may be based on a selection by another organization such as Company Y. This is to allow Company Y to control its disclosure items, for example, because there is a need to disclose only GHG emission amount per unit and not specific numerical values ​​such as activity amount.

[0073] In the present embodiment, a device etc. that derives GHG emissions for each product from the activity amount etc. of an organization has been described. In other embodiments, it may be possible to link only the activity amount etc. of related organizations according to a standard etc. (e.g., Pathfinder Framework) for deriving GHG emissions for each product among the activity amount etc. of the organizations, or to display GHG emissions derived based only on the activity amount etc. of such organizations.

[0074] For example, when the use of the above standard is selected, the organization's activities that can be linked to product information may be limited to activities that can be used for the above standard. Specifically, when the use of a standard that does not directly relate to the manufacturing process (e.g., indirect activities such as employee business trips) should not be used to derive GHG emissions for each product is selected, the organization's activities may be hidden or made unselectable from the list of activities to be linked to product information. In this case, the correspondence between the standard and the organization's activities may be registered in advance as being compatible or non-compatible in each of categories 1-15 of scope 1-2 and scope 3. In addition, the correspondence between the standard and the organization's activities may be registered in advance as direct activities or indirect activities in each of categories 1-15 of scope 1-2 and scope 3, and the correspondence or non-compatibility may be determined based on the direct activities and indirect activities. Here, direct activities are activities related to the target product that are directly related to the production of the product, and indirect activities are activities related to the target product that are not direct activities.

[0075] Also, for example, when the use of the above standard is selected, the GHG emissions for each product may be derived using only activities that can be used for the above standard among the activities of the organization linked to the product information. In this case, the GHG emissions for each product may be displayed so that the GHG emissions when the above standard is used can be compared with the GHG emissions when the above standard is not used. For example, when the use of a standard that calculates the GHG emissions for each product only from direct activities is selected, the GHG emissions for each product may be displayed so that the GHG emissions calculated only from direct activities and the GHG emissions calculated from direct activities and indirect activities can be displayed in close positions, such as left and right or up and down, or in the same position so that they can be switched by a pull-down or the like. Here, the GHG emissions for each product may be displayed so that they can be compared in total and at least one by scope category. In the above other embodiment, the GHG emissions for each product using the above standard may be displayed to other organizations through this system. This allows the GHG emissions (emission coefficients) to be linked between organizations in the supply chain.

A program installed on the computer 1200 may cause the computer 1200 to perform operations associated with an apparatus according to an embodiment of the present invention or one or more "parts" of the apparatus. Alternatively, the program may cause the computer 1200 to execute the operations or one or more "parts". The program may cause the computer 1200 to execute a process or steps of the process according to an embodiment of the present invention. Such a program may be executed by the CPU 1212 to cause the computer 1200 to execute specific operations associated with some or all of the blocks of the flowcharts and block diagrams described herein.

[0077] The computer 1200 according to this embodiment includes a CPU 1212 and a RAM 1214, which are connected to each other by a host controller 1210.

[0078] The communication interface 1222 communicates with other electronic devices via a network. The hard disk drive may store programs and data used by the CPU 1212 in the computer 1200. The ROM 1230 stores a boot program executed by the computer 1200 when activated and / or a program that depends on the hardware of the computer 1200. The programs are provided via a computer-readable recording medium such as a CD-ROM, a USB memory, or an IC card, or a network.

The CPU 1212 may also search for information in a file, database, etc. in the recording medium. For example, when a plurality of entries each having an attribute value of a first attribute associated with an attribute value of a second attribute are stored in the recording medium, the CPU 1212 may search for an entry that matches a condition, in which the attribute value of the first attribute is specified, from among the plurality of entries, read the attribute value of the second attribute stored in the entry, and thereby obtain the attribute value of the second attribute associated with the first attribute that satisfies a predetermined condition.

[0082] The above-described programs or software modules may be stored in a computer-readable storage medium on the computer 1200 or in the vicinity of the computer 1200. Also, a recording medium such as a hard disk or a RAM provided in a server system connected to a dedicated communication network or the Internet can be used as a computer-readable storage medium, thereby providing the programs to the computer 1200 via the network.
