Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. Furthermore, not all combinations of features described in the embodiments are essential to the solution of the invention.

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

FIG. 2 shows an example of each part constituting the derivation device 100. The derivation device 100 includes an acquisition section 102, a derivation section 104, a ratio reception section 106, an emission factor reception section 108, a presentation section 110, and a production amount reception section 112. The derivation device 100 according to this embodiment may be a computer. The computer has a CPU, various memories such as ROM, RAM, and EEPROM (registered trademark), a communication bus, and an interface. 100. Each unit included in the derivation device 100 may be configured by installing a program that is stored in a computer-readable recording medium, 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 causing the computer to execute programs that perform various processes for deriving GHG emissions, thereby causing the computer to function as each unit included in the derivation device 100.

In recent years, it has become possible to understand the entire organization's activities by deriving not only the greenhouse gas emissions (GHG emissions) of the business itself, but also supply chain emissions, which indicate the GHG emissions of all supply chains involved in business activities. , attempts are being made to manage it. Supply chain emissions indicate the amount of GHG emissions generated by an organization's activities throughout the entire flow, including raw material procurement, manufacturing, distribution, sales, and disposal. Supply chain emissions are comprised of Scope 1, Scope 2, and Scope 3.

Scope 1 indicates direct emissions, which represent the amount of greenhouse gas emissions directly emitted by the business itself. Scope 2 refers to indirect emissions that indicate the amount of greenhouse gases emitted indirectly when businesses purchase energy such as electricity, heat, steam, etc. from other companies such as electric power companies, and use the purchased energy. (indirect emissions from energy sources). Scope 3 indicates other indirect emissions, which represent greenhouse gas emissions emitted by businesses' activities in their supply chains that are not included in Scope 1 or Scope 2. Scope 3 is further classified into 15 categories depending on the activity content.

Category 1 indicates "purchased products/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 "transportation, conveyance (upstream)". Category 5 indicates "waste generated from business activities." Category 6 indicates "business trip." Category 7 indicates “employee commuting”. Category 8 indicates “lease assets (upstream)”. Category 9 indicates "transportation, delivery (downstream)". Category 10 indicates "processing of sold products." Category 11 indicates "use of sold products." Category 12 indicates "disposal of sold products". Category 13 indicates “lease assets (downstream)”. Category 14 indicates "franchise." Category 15 indicates "investment". Scope 3 further includes “Other” which indicates indirect GHG emissions not included in the 15 categories. The GHG emissions that fall under "Others" include, for example, the GHG emissions related to the daily lives of employees or consumers.

Supply chain emissions are the sum of Scope 1, Scope 2, and Scope 3 emissions. The basic formula for Scope 1 to Scope 3 is activity amount x emissions intensity. For Scope 3 emissions, basic formulas are derived for each of the 15 categories and summed. The amount of activity 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, the amount of various transactions, etc. The amount of activity is collected from various data within the organization regarding the product or service, literature data, industry average data, design values, etc. Emission intensity is the amount of GHG emissions per amount of activity. For example, this includes GHG emissions per 1 kWh of electricity used, GHG emissions per 1 ton-kilometer of freight transported, GHG emissions per 1 ton of waste incineration, etc. Emission intensity values are basically selected and used from existing databases, but there are also methods of directly measuring emissions or receiving the results of deriving emissions from business partners.

By the way, especially in the manufacturing industry, the company calculates the GHG emissions for each product, and then tells the delivery company how to calculate the GHG emission coefficient (also called carbon footprint (Cradle-to-Grave)) per product. The major issue is how to provide this information to the public.

Therefore, the present embodiment provides a derivation device, a derivation method, and a program that can calculate the GHG emission amount for each product and derive the GHG emission coefficient for each product. Note that in this embodiment, products also include services. Furthermore, in this embodiment, an organization is not limited to a company, but broadly includes private businesses, government offices, local governments, schools, unions, groups, and the like.

3A, FIG. 3B, FIG. 3C, FIG. 3D, and FIG. 3E show GHG emissions information indicating greenhouse gas emissions (GHG emissions) for each activity content of an organization. The GHG emissions information shown in FIG. 3A is a table created by combining the tables shown in FIGS. 3B to 3E, which are stored in association with each other in the Company X database 200. From this, we will derive the total GHG emissions from April 1, 2021 to March 31, 2022 for Product A, which is one of the products of Company X. First, information regarding product A is registered.

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 "Y factory" from the pull-down menu. In the delivery destination processing area box B24, select "Z Factory" from the pull-down menu. Enter the power supply point identification number in the supply point identification number box B16. The power supply point identification number of the delivery destination is entered in the delivery destination supply point identification number box B26. Enter "1,000,000" into the production number box B18 and the sales number box B20, respectively. For production year B22, select "2021" from the pulldown. The screen in FIG. 4 is only an example, and may include more or fewer items.

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

The acquisition unit 102 acquires GHG emissions information in FIG. 3A that has a period from April 1, 2021 to March 31, 2022, and includes "Common" or "Product A" in the "Remarks" column C1. Query with the following conditions and extract all matching rows. "Common" in the "Remarks" column indicates that the corresponding row is data that is commonly applied not only to product A but to multiple products. "Product A" in the "Remarks" column indicates that the corresponding row is data that applies only to Product A.

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

The derivation unit 104 derives the total GHG emissions related to the product based on the GHG emissions for each activity content 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 the sum of 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 percentage of product sales, a percentage of sales of products handled by the organization, or the like. For example, Company X handles two products: Product A and Product B. Therefore, the derivation unit 104 may derive 406150.25 by multiplying 812300.5 by a predetermined coefficient of 0.5 for product A. As a result, the total GHG emissions related to product A are derived as 406150.25.

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

Alternatively or in addition to this, the derivation device 100 may further include a ratio reception 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 a ratio to GHG emissions. Referring to FIG. 6, a "ratio" column C10 and a "GHG emissions amount after multiplication" column C12 are added to the table shown in FIG. 5. The value input in the “ratio” column C10 is accepted by the ratio reception unit 106. In the table in Figure 6, electricity consumption in the first line, gasoline consumption in the second line, screw purchases in the third line, and business trips in the fourth line are indicated as ``common'' in the ``Remarks'' column. Therefore, this data applies not only to product A but to multiple products of company X. Therefore, we will specify the proportion of product A in these "common" data. The ratio of product A to electricity usage on April 1, 2021 is 50%. Therefore, the ratio accepting unit 106 accepts the user's designation of “50%”. Similarly, the ratio reception unit 106 also receives ratio specifications for gasoline usage, screw purchases, and business trips. Regarding the purchase of packaging materials for product A and the delivery of product A, no ratio is specified because the data applies only to product A. When the user finishes specifying the ratio and clicks the ratio registration button D1, "ratio" is added to each value in the "GHG emissions" column C14 in the "GHG emissions after multiplication" column C14 adjacent to the "ratio" column C10. The value obtained by multiplying each value in column C10 is automatically displayed. For the purchase of packaging materials for product A and the delivery of product A without specifying a ratio, when you click the ratio registration button D1, 100% is automatically entered in the "ratio" column C10, and the "GHG emissions after multiplication" column is automatically entered. The value of the "GHG emissions" column C14 is copied to C12.

The derivation unit 104 derives the total GHG emissions by multiplying the GHG emissions for each activity content of the organization related to the product by each ratio and summing the multiplied GHG emissions. A calculation formula is set in advance in the SUM (GHG emissions after multiplication) field F12 in FIG. 6, and when the ratio registration button D1 is clicked, all values included in the "GHG emissions after multiplication" column C12 are set. Display the total value. The derivation unit 104 derives the total GHG emissions of product A by reading the value of the SUM (GHG emissions after multiplication) field F12. Note that the ratio may be determined in advance. For example, it may be determined in advance based on the ratio of the number of products produced, the ratio of production time, etc. Alternatively, it may be designed to accept specification of actual measured values instead of ratios. As explained later, the total GHG emissions of Product A derived here include processing of sold products (Category 10), use of sold products (Category 11), and disposal of sold products (Category 12). GHG emissions are not included.

GHG emissions by activity content of an organization are divided into direct emissions, which shows the amount of GHG emissions directly emitted by the organization, and indirect emissions, which shows the amount of GHG emissions indirectly emitted by the organization through the purchase of energy. emissions and other indirect emissions, which represent GHG emissions emitted by an organization's activities that are not included in direct emissions and indirect emissions. In the table shown in FIG. 6, the amount of gasoline used in the second line corresponds to Scope 1, that is, direct emissions indicating the amount of GHG emissions directly emitted by the organization. The amount of electricity used in the first line corresponds to Scope 2, that is, indirect emissions that indicate the amount of GHG emissions indirectly generated by an organization's energy purchases. The purchase of screws in the third row, the business trip in the fourth row, the purchase of packaging materials for product A in the fifth row, and the delivery of product A in the last row are not included in Scope 3, that is, direct and indirect emissions. It corresponds to other indirect emissions that represent the amount of GHG emissions emitted by an organization's activities.

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 calculates the emission coefficient of GHG emissions of at least one of the processing, use, and disposal of products, and the activity amount according to the emission coefficient. The apparatus further includes an emission factor reception unit 108 that receives an emission factor. The derivation unit 104 derives the total GHG emissions based on the GHG emissions for each activity content of the organization acquired by the acquisition unit 102, and at least one GHG emission emission coefficient and activity amount. The activity information in Figure 6 does not include GHG emissions from processing of sold products (Category 10), use of sold products (Category 11), and disposal of sold products (Category 12). The reason is that for category 10, category 11, and category 12, the subject is not organization X but the product sales destination. Therefore, it is necessary to derive GHG emissions for each of product processing, use, and disposal separately. In order to derive GHG emissions from processing, use, and disposal, it is necessary to have the delivery destination set up a scenario for processing, use, and disposal, and provide the emission factors and activity data associated with processing, use, and disposal. desirable. Emission factors and activity data may be obtained from the delivery destination using a blockchain.

FIG. 7 shows a screen for accepting emission factors and activity amounts related to processing, use, and disposal of products, which is an example of a screen for inputting emission factors accepted by the emission factor reception unit 108. Here, according to the information registered in FIG. 4, it is assumed that product A is a personal computer, and the sales volume in 2021 is 1 million units. The personal computer in this description is assumed to be an intermediate product on which an OS and other applications are preinstalled by the manufacturer upon delivery to the manufacturer.

First, GHG emissions related to the processing of products sold in category 10 are derived. As a scenario for processing personal computers, let's assume that it takes one hour for each computer to install a program at the destination manufacturer. Further, the power consumption per hour is assumed to be 0.1 kWh, and the emission coefficient is assumed to be 0.0004530 (t-CO ₂ /kWh). Therefore, in the "Specify emission factor and activity amount related to processing of sold products" area, enter "0.1 (kWh) x 1 (h) x 1,000,000 (pieces)" in the "Activity amount" field F20. input. Enter "0.0004530 (t-CO ₂ /kWh)" in the "emission factor" 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 the amount of sales may be input as the activity amount, and the CO ₂ equivalent amount per unit sold may be input 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. The present embodiment is not limited in this respect as long as the GHG emissions related to the processing of sold products can be derived.

Next, GHG emissions related to the use of the sold products are derived. Category 11 GHG emissions are the number of products sold in the reporting year multiplied by their lifetime emissions. As for the PC usage scenario, we obtained information from the specifications that the annual power consumption is 1,350 kWh and the average service life is 5 years. The emission coefficient is set to 0.0004530 (t-CO ₂ /kWh), which is the same as in the case of processing. Therefore, in the "Specify the emission factor and activity amount related to the use of sold products" area, enter "1350 (kWh) x 5 (year) x 1,000,000 (units)" in the "activity amount" field F26. . Enter "0.0004530 (t-CO ₂ /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 the amount of sales may be input as the activity amount, and the CO ₂ equivalent amount per unit sold may be input 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. The present embodiment is not limited in this respect, as long as GHG emissions related to the use of sold products can be derived.

Next, GHG emissions related to the disposal of sold products are derived. The scenario for disposing of a computer is that the computer is a combination of the main body and display, has an estimated weight of 8.09 kg, and will be recycled with transportation. In this case, the emission coefficient per vehicle is 0.000521 (t-CO ₂ /vehicle). Therefore, in the "Specify emission coefficient and activity amount related to disposal of sold products" area, enter "1,000,000 (items)" in the "activity amount" field F32. Enter "0.000521 (t-CO ₂ /vehicle)" in the "emission factor" field F34. Then, "521" is displayed in the "GHG emissions (disposal)" field F36 where the calculation formula is set.

A SUM (process, use, discard) field F40 is arranged in the area designated as B1 in FIG. A calculation formula is set in the SUM (processing, use, disposal) field F40, and includes the "GHG emissions (processing)" field F24, the "GHG emissions (use)" field F30, and the "GHG emissions (disposal)" field. A total value of 65798.3, which is the sum of the values in field F36, is automatically displayed.

A SUM (A1+B1) field F42 is provided in the area indicated as C1 in FIG. In SUM (A1+B1) field F42, the value of SUM (GHG emissions after multiplication) shown in area A1 of Figure 6 is added to the value "65798.3" of SUM (processing, use, disposal) field F40. A value has been entered. Here, it is assumed that the multiplied GHG emission amount shown in area A1 in FIG. 6 is 453,215. The derivation unit 104 reads the value 519013.3 displayed in the SUM (A1+B1) field F42, thereby calculating the GHG emissions for each activity content of the organization acquired by the acquisition unit 102 and the emission of at least one GHG emission amount. The total GHG emissions are derived based on the coefficient and the amount of activity. Note that the above explanation was given for the case where product A is an intermediate product. If product A is a finished product, the display in FIG. 7 does not need to include the "specify emission factor and activity amount related to processing of sold product" area.

To summarize the above, when the product is a finished product that does not require processing, the emission factor reception unit 108 receives each emission coefficient for use and disposal of the product and each amount of activity corresponding to each emission coefficient, and the derivation unit 104 derives the total GHG emissions based on the GHG emissions for each activity content of the organization acquired by the acquisition unit 102, each emission coefficient, and each activity amount. On the other hand, if the product is an intermediate product that requires processing, the emission factor reception unit 108 receives each emission factor for processing, use, and disposal of the product and each activity amount corresponding to each emission factor, and the derivation unit 104 receives , the total GHG emission amount is derived based on the GHG emission amount for each activity content of the organization obtained by the acquisition unit 102, each emission coefficient, and each activity amount.

Note that when accepting the specification of an emission factor in each "emission factor" column for product processing, use, and disposal, 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 selects a value selected from the at least one emission factor presented by the presentation unit 110. Accept the emission factor as an emission factor. FIG. 8A shows a diagram illustrating an example of a screen displaying emission factors presented by the presentation unit 110. When the presenting unit 110 presents at least one emission factor, the presenting unit 110 may present the emission factor from the emission intensity database 300 in FIG. 1 . Within the emission intensity database 300, the emission coefficient may be stored in association with, for example, information about the electric power company. As shown in FIG. 8A, when a unit is selected from the pulldown in 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 factor is selected from the list, the emission factor receiving unit 108 receives the selected emission factor as an emission factor.

Furthermore, the presentation unit 110 selects at least one emission factor from among the emission factors assigned in advance for each point, in order of proximity to the point where the product is used, disposed of, or processed. Presented as. The point assigned to each emission factor may be the location where the power generation equipment is installed. The presenting unit 110 refers to the destination processing area registered in the destination processing area box B24 on the screen shown in FIG. The processed area may be displayed on the input screen. When the unit of electric power is specified in the pull-down menu in the "Unit" column C30, the presentation unit 110 presents a list of the emission factors of the power supply companies closest to the processing site Z factory in the "Emission factor" column C32 in descending order. It's fine.

In addition, the presentation unit 110 selects a plurality of emission coefficients from among emission coefficients assigned in advance for each point in order of proximity to the point where the product is used, disposed of, or processed, in descending order of at least one emission factor. May be presented as one emission factor. For example, if there are multiple power supply companies in the same area, they may be sorted and presented in descending order of emission factors, as shown in FIG. 8B.

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 close to the point determined by the supply point identification number in descending order of the distance. If there are multiple power supply companies near the point determined by the supply point identification number, they may be further sorted and presented in descending order of emission coefficient. In addition, when presenting the emission factor, the average emission factor for the entire power system in the area where the organization operates may be presented based on location criteria. Alternatively, the emission coefficient 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 coefficient is output. Furthermore, the emission factors may be presented in descending order of usage rate based on the industry of the organization.

Referring again to FIG. Up to this point, the SUM (A1 + B1) field F42 shown in C1 contains the GHG emissions of product A by organization A total value with emissions has been derived. From this, we will derive the GHG emission coefficient as the carbon footprint per product A.

The derivation device 100 further includes a production amount receiving unit 112 that receives the production amount of the product, and the derivation unit 104 receives the product's GHG emission amount per product based on the total GHG emission amount and the production amount. Derive emission factors. FIG. 9 shows a screen for calculating the emission coefficient per product A, which is an example of a production amount input screen accepted by the production amount reception 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 number 1,000,000 shown in FIG. 4 is copied to the "Production Number" column C42. When these values are confirmed to be correct, the user clicks the execution button D2. As a result, 0.5190133 is displayed in column C44 of "C÷number of production=GHG emissions per product". The derivation unit 104 reads the value 0.5190133 displayed in the “C÷Production quantity=GHG emissions per product” column C44, and calculates the GHG emissions of the A product, which indicates the GHG emissions per one product. Derive emission factors. In the above explanation, the production quantity is the sum of the GHG emissions of product A after ratio multiplication in field A1 and the GHG emissions of product A related to processing, use, and disposal in field B1. By dividing, the emission factor per product A was derived. In addition, the GHG emissions of product A after ratio multiplication in field A1 divided by the number of production, and the GHG emissions of product A related to processing, use, and disposal in field B1 divided by the number of production. The emission coefficient for each product A may be derived by summing the values. In addition, it is also possible to calculate the GHG emission reduction contribution amount for comparison products (old products, etc.). To do this, for example, it can be derived by multiplying the difference between the GHG emissions per comparison product and the GHG emissions per product A by the amount of popularization of product A. Furthermore, the carbon tax may be derived using the derived GHG emissions per product A and displayed in accordance with a format such as financial information.

FIG. 11 is a flowchart for deriving the emission coefficient of a product indicating the amount of GHG emissions per product using the derivation device 100 according to the present embodiment.

In S200, the emission factor reception unit 108 refers to the registered product information and determines whether the product is a finished product or an intermediate product.

If the product is an intermediate product, the process advances to S202. The emission factor reception unit 108 receives each emission factor for processing, use, and disposal of a product, and each amount of activity corresponding to each emission factor.

In S204, the derivation unit 104 totals the GHG emissions of processing, use, and disposal.

As described above, according to the present embodiment, the GHG emissions for each product can be derived using the supply chain emissions, and the GHG emission coefficient for each product can be efficiently derived. Since the existing supply chain emissions can be used, an increase in the processing load and memory capacity of the derivation device 100 can be suppressed. By deriving GHG emissions from product processing, use, and disposal from separately accepted emission factors and activity data, without using the organization's supply chain emissions, GHG emissions per product can be calculated more accurately. Coefficients can be derived. In this embodiment, at least one of the activity amount, emission coefficient, and GHG emissions of the organization of Company X is linked to the products of Company X, but in other embodiments, instead of this, At least one of the amount of activity, the emission factor, and the amount of GHG emissions may be linked to the product of Company X. For example, Company X's Scope 3 Category 1 GHG emissions may be calculated from the activity amount and emission coefficient of Company Y's organization that Company Y (separate account) inputs through this system. Then, the products of company X may be linked to the GHG emissions derived based on the input of company Y.

Further, as another example, the emission factor linked to the product of Company A (for example, a wholesaler) may be an emission factor for processing the product set by Company B (for example, a manufacturer) through this system. In the above-described other embodiments, which of the activity amounts, emission factors, and GHG emissions linked to the products of Company X are to be disclosed to Company X may be based on a selection by another organization such as Company Y. This is to enable Company Y to control its own disclosure items; for example, there is a need to disclose only GHG emissions per unit and not disclose specific figures such as activity amounts. It is.

Furthermore, in this embodiment, an apparatus and the like for deriving the GHG emissions for each product from the activity amount of an organization and the like is shown. In another embodiment, among the activity amounts of organizations, only the activity amounts of related organizations are linked according to standards for deriving GHG emissions for each product (for example, Pathfinder Framework), or the activities of such organizations are linked. It may be possible to display the amount of GHG emissions derived only based on the amount or the like.

For example, if it is selected to use the standard, the activities of the organization that can be linked to product information may be limited to activities that can be used in the standard. Specifically, if an organization chooses to use standards that are not directly related to manufacturing processes (e.g., indirect activities such as employee business trips) to derive GHG emissions for each product, The activities of such organizations may be hidden or not selectable from the list of activities associated with product information. In this case, correspondence or non-correspondence between the standard and the organization's activities may be registered in advance for each of categories 1-15 of scope 1-2 and scope 3. In addition, regarding the correspondence between these standards and organizational activities, direct activities or indirect activities are registered in advance for each activity in Scope 1-2 and Scope 3 Categories 1-15, and correspondence is based on the relevant direct and indirect activities. - It may be determined that the item is not compatible. Here, direct activities are activities related to the target product that are directly related to the manufacturing of the target product, and indirect activities are activities related to the target product that are not direct activities.

Also, for example, if you choose to use the above standards, GHG emissions for each product may be derived in which only activities that can be used in the above standards are used 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 and the GHG emissions when the above standard is not used can be compared. For example, if you choose to use the standard that GHG emissions by product are calculated only from direct activities, GHG emissions by product will be calculated from GHG emissions only from direct activities and GHG emissions from direct activities and The GHG emissions calculated from indirect activities may be displayed in adjacent positions such as left and right or top and bottom, or they may be displayed in the same position so that they can be switched by pull-down or the like. Here, the GHG emissions for each product may be displayed for comparison in at least one of the total and each scope category. In other embodiments described above, GHG emissions per product using the standards may be displayed to other organizations through the system. This makes it possible to coordinate GHG emissions (emission factors) between organizations in the supply chain.
