[0004] Patent Document 1: Japanese Patent No. 7084584 SUMMARY OF THE INVENTIONTechnical Problem

[0005] With regard to the GHG emission amount that a company must report, it is obliged to calculate the greenhouse gases emitted at each stage of its business activities, for example, raw material procurement, manufacturing, logistics, sales, disposal, and the like, which are GHG emission amounts of other companies (trading partner companies) that are related to its business activities.

[0006] For example, there is a system where a company calculates a ratio of its own activity volume (physical volume or monetary data) to the activity volume of other companies with respect to a corresponding activity and determines an emission quantity for each category by multiplying the calculated ratio by the GHG emission quantities of the other companies and the emission coefficients (also called emission base units) published by various organizations.

[0007] However, to calculate the GHG emission amount, it is necessary to organize and inquire with trading partner companies and the like to calculate the emission amount for each trading partner company, which requires a lot of labor and time.

[0010] In addition, an information processing method according to another aspect of the present invention includes storing, by a company database, sales amounts and greenhouse gas emission amounts of companies, detecting, by a detection unit, transaction amounts between a reporting company and trading partner companies, and calculating, by an emission amount calculation unit, assigned emission amounts of the trading partner companies assigned to the reporting company using the sales amounts and greenhouse gas emission amounts of the trading partner companies stored in the company database and the transaction amounts detected by the detection unit.

[0011] In addition, according to yet another aspect of the present invention, a program causes an information processing device that is a computer to store sales amounts and greenhouse gas emission amounts of enterprises, detect transaction amounts between a reporting enterprise and trading partner enterprises, and calculate allocated emission amounts of the trading partner enterprises that are allocated to the reporting enterprise using the stored sales amounts and greenhouse gas emission amounts of the trading partner enterprises and the detected transaction amounts. Advantageous effects of the invention

[0012] According to the present invention, the amount of GHG emission can be easily calculated.

[0013] An embodiment of the present invention will be described below with reference to the drawings. In the following description, an example of calculating the emission amount for each category according to Scope 3 defined in a Greenhouse Gas Protocol will be described in the present embodiment. However, the present invention is not limited to this, and the present embodiment can be used to calculate any GHG emission amount defined in various ways.

[0014] Fig. 1 is a block diagram showing a configuration of an information processing system 1 of an embodiment. The information processing system 1 includes, for example, an information processing device 10, an enterprise database 20, and a plurality of enterprise terminals 30 (enterprise terminals 30-1, 30-2, ..., 30-N, where N is an arbitrary natural number). The components of the information processing system 1, namely, the information processing device 10, the enterprise database 20, and the plurality of enterprise terminals 30, are communicatively connected to each other via a communication network NW.

[0015] The information processing system 1 is a system that provides a service (hereinafter referred to as a calculation service) that calculates an emission amount corresponding to Scope 3. The calculation service is provided, for example, via dedicated application software (hereinafter referred to as a calculation application), a web browser, or the like.

[0016] The enterprise terminal 30 is a computer managed by a company or the like that uses the calculation service. For example, a server device, a cloud server, a personal computer (PC), a tablet terminal, or the like can be applied as the enterprise terminal 30. For example, it is assumed that a reporting company that reports the emission amount corresponding to Scope 3 in the company is the company that uses the calculation service. For example, a responsible person or the like uses the enterprise terminal 30 to register for use of the calculation service, and the like. This makes it possible for the enterprise terminal 30 to use the calculation service.

[0017] The information processing device 10 is a computer managed by a company or the like that provides the calculation service. For example, a server device, a cloud server, a personal computer (PC), or the like can be used as the information processing device 10. The information processing device 10 calculates the emission amount corresponding to Scope 3 in response to a request from the company terminal 30. The following describes a method by which the information processing device 10 calculates the emission amount corresponding to Scope 3.

[0018] The enterprise database 20 is a database that stores information about enterprises (enterprise information 201). For example, a server device, a cloud server, a personal computer (PC), or the like can be used as the enterprise database 20. The enterprise database 20 includes a storage area consisting of a storage medium such as a hard disk, a flash memory, an electrically erasable programmable read-only memory (EEPROM), a random access memory (RAM), a read-only memory (ROM), or a combination thereof. The enterprise database 20 stores the enterprise information 201 in this storage area.

[0019] In the example from Fig. 1 illustrates a case where the information processing device 10 and the enterprise database 20 are separate devices, but the present invention is not limited thereto. The enterprise information 201 may be stored within the information processing device 10. In this case, the enterprise database 20 may be omitted.

[0020] Fig. 2 is a diagram showing an example of the company information 201 of one embodiment. The company information 201, as information about a company, includes information corresponding to items such as the company's GHG emission amount, sales revenue, total assets, and the number of shares issued.

[0021] The GHG emission quantity is the amount of GHG emitted by a company. The amount of carbon dioxide (CO2) emitted by a company can also be used as a GHG emission quantity. The GHG emission quantity can be collected, for example, from the Carbon Disclosure Project (CDP) database, from sustainability reports published by the respective companies, and from information such as the GHG emission quantity calculated by the company itself as part of a GHG emission calculation, reporting, and disclosure system (GHC).

[0022] Sales revenue, total assets, and number of shares outstanding are the sales revenue, total assets, and number of shares outstanding of a company. Sales revenue, total assets, and number of shares outstanding can be obtained, for example, from information such as company information published by a company on a website or similar, securities reports, annual financial statements, and financial announcements published in an official gazette.

[0023] The company database 20 also stores an emission base unit for each Scope 3 category. The emission base unit can, for example, be taken from an emission base unit database that is created as an emission factor in the SHK system.

[0024] The company database 20 is used, for example, by regularly or irregularly accessing information published on the Internet, for example a CDP database or similar, and updating information such as the GHG emission quantity stored as company information 201.

[0025] The following describes the method by which the information processing device 10 calculates the emission quantity corresponding to Scope 3.

[0026] As in Fig. 1, the information processing device 10 includes, for example, a detection unit 101, a first emission amount calculation unit 102, and a second emission amount calculation unit 103. Functional units of the information processing device 10, that is, the detection unit 101, the first emission amount calculation unit 102, and the second emission amount calculation unit 103, are realized by causing a central processing unit (CPU) provided as hardware by the information processing device 10 to execute a program.

[0027] The recording unit 101 records the data required to calculate the emission volume according to Scope 3. The data required to calculate the emission volume according to Scope 3 here is, for example, information indicating a transaction volume between a reporting company and a trading partner company. The data required to calculate the emission volume according to Scope 3 may include information indicating the number of shares of the trading partner company held by the reporting company.

[0028] For example, when a calculation application is started by a responsible person or the like of the reporting company operating the enterprise terminal 30, or when a Uniform Resource Locator (URL) for using the calculation service is accessed via a web browser or the like, the information processing device 10 transmits to the enterprise terminal 30 an input screen (see Fig. 9) to calculate the emission quantity corresponding to Scope 3. As a result, an input screen is displayed on the company terminal 30 as in Fig. 9. The responsible person or the like of the reporting enterprise inputs data such as the transaction amount for each trading partner enterprise of the reporting enterprise according to the content displayed on the input screen and performs the registration work by pressing a registration button or other operations. As a result, the enterprise terminal 30 transmits to the information processing device 10 data such as the transaction amount for each trading partner enterprise of the reporting enterprise, which is data necessary for calculating the emission amount corresponding to Scope 3. The acquisition unit 101 acquires the data thus transmitted from the enterprise terminal 30 to the information processing device 10.

[0029] The first emission quantity calculation unit 102 calculates an allocated emission quantity for each trading partner company using the company information 201 stored in the company database 20 and the data collected by the collection unit 101. Here, the allocated emission quantity is an emission quantity allocated to the reporting company from the GHG emission quantity emitted by the trading partner company.

[0030] Here, a method by which the first emission amount calculation unit 102 calculates the allocated emission amount is described using Fig. 3 to 5 are described in detail. Fig. 3 to 5 are diagrams for describing the processing performed by the information processing apparatus 10 of the embodiment.

[0031] Fig. Figure 3 shows a calculation formula K1 for the allocated emission volume and the like described in the Guidelines. As shown in the calculation formula K1, the emission volume allocated to the reporting company (allocated emission volume) is calculated by multiplying the "emission volumes of trading partner companies" by a first ratio. Here, the first ratio is a "physical and economic share of the reporting company" with respect to a "total physical and economic volume of trading partner companies."

[0032] As in Fig. As shown in Figure 3, the calculation formula K1 for the allocated emission quantity and the like described in the Guidelines is very abstract, and knowledge of how to determine the physical quantities corresponding to, for example, "the total physical and economic quantity of the trading partner enterprises" and the "physical and economic share of the reporting enterprise" was required. In addition, the calculation formula K1 is defined under the premise that the calculation is performed using the data of the trading partner enterprises. For this reason, the specific calculation method chosen is a method in which the trading partner enterprises perform the calculation using the calculation formula K1, and the allocated emission quantity is calculated by collecting a calculation result (allocated emission quantity) from the trading partner enterprises.Therefore, the reporting company had to request the allocated emission volume from the trading partner companies, which required a lot of work and time.

[0033] To solve this problem, the information processing system 1 of the embodiment uses information such as the sales revenue disclosed by the trading partner company, so that it is possible to calculate the allocated emission amount using only data from the reporting company. Specifically, the first emission amount calculation unit 102 calculates the allocated emission amount using a calculation formula K2, which is a modified version of the calculation formula K1, the company information 201, and the "transaction amount of the reporting company," which is data from the reporting company.

[0034] Fig. Figure 4 shows the calculation formula K2 for calculating the allocated emission quantity in the embodiment. As shown in the calculation formula K2, the allocated emission quantity is calculated by multiplying the "emission quantity of the trading partner company" by a second ratio. The second ratio is the "transaction quantity of the reporting company" divided by the "sales revenue of the trading partner company."

[0035] By further modifying the calculation formula K2, the allocated emission quantity can be obtained by multiplying the "reporting enterprise transaction quantity" (a character D2) by a third ratio. The third ratio is the "trading partner emission quantity" relative to the "trading partner sales revenue" (a character D1). Here, the third ratio indicated by character D1 can be extracted based on the information stored in the enterprise information 201. In addition, the "reporting enterprise transaction quantity" indicated by character D2 is data of the reporting enterprise and can be obtained, for example, by extracting purchasing data showing transactions with trading partner enterprises from the reporting enterprise's purchasing data.

[0036] In this way, in the information processing system 1 of the present embodiment, the allocated emission amount can be calculated using only information such as sales revenues disclosed by the trading partner companies and data of the reporting company based on the calculation formula K1 described in the guidelines, etc. Furthermore, the company database 20 stores the information disclosed by the trading partner companies, such as sales revenues.

[0037] Then, the first emission quantity calculation unit 102 refers to the enterprise database 20 based on the "trading partner enterprise sales revenue" transmitted from the enterprise terminal 30 and acquires the "trading partner enterprise emission quantity" and the "trading partner enterprise sales revenue" for that trading partner enterprise. The first emission quantity calculation unit 102 calculates the allocated emission quantity using the "trading partner enterprise sales revenue" transmitted from the enterprise terminal 30 and the "trading partner enterprise emission quantity" and the "trading partner enterprise sales revenue" acquired from the enterprise database 20. The allocated emission quantity thus calculated is transmitted to the enterprise terminal 30.

[0038] As a result, the reporting company can calculate the allocated emission quantity of the reporting company in the trading partner company by simply submitting the transaction quantity with the trading partner company in the reporting company to the calculation service at any time when the reporting company intends to calculate the allocated emission quantity. Therefore, there is no need to consider how to determine a physical quantity corresponding to the "total physical and economic quantity of the trading partner company" and the "physical and economic share of the reporting company" or to make a request to the trading partner company. For this reason, it is possible to calculate the allocated emission quantity without significant time and effort.

[0039] Fig. Figure 5 shows how the calculation formula K1 is interpreted for each category of Scope 3. As in Fig. As shown in Figure 5, the calculation formula K1 can be modified accordingly for each category.

[0040] As in Fig. For example, as shown in Figure 5, when calculating the allocated emission quantities for Category 1, Category 2, Category 4, and Category 9 of Scope 3, the "physical and economic share of the reporting company" in the calculation formula K1 is set to the "transaction volume of the reporting company." In addition, the "total physical and economic volume of trading partner companies" in the calculation formula K1 is set to the "sales revenue of trading partner companies." In this way, the allocated emission quantity can be calculated according to the calculation formula K2 described above.

[0041] As in Fig. 5, for example, when calculating the allocated emission quantity for category 15 of Scope 3 on a monetary basis, the "physical and economic share of the reporting company" in the calculation formula K1 is set to an "investment quantity of the reporting company." The "investment quantity of the reporting company" here is a quantity that the reporting company invests in the trading partner companies. The "investment quantity of the reporting company" is data of the reporting company and can be determined, for example, by extracting it from the investment data of the reporting company. In addition, the "total physical and economic quantity of the trading partner companies" in the calculation formula K1 is set to a "balance sheet total quantity of the trading partner companies." The "balance sheet total quantity of the trading partner companies" can be extracted from the company database 20.For example, the first emission quantity calculation unit 102 may calculate the allocated emission quantity for category 15 of Scope 3 on a monetary basis using formula (1). Allocated emission volume = emission volume of the trading partner company / balance sheet total of the trading partner company × investment volume of the reporting company

[0042] Alternatively, as in Fig. 5, when calculating the allocated emission volume for Category 15 of Scope 3 on a share basis, for example, the "physical and economic share of the reporting company" in the calculation formula K1 is set to the "number of shares held by the reporting company." The "number of shares held by the reporting company" here is the number of shares of the trading partner company held by the reporting company. The "number of shares held by the reporting company" is data from the reporting company and can be determined, for example, from data for shares held by the reporting company. In addition, the "total physical and economic volume of the trading partner company" in the calculation formula K1 is set to the "total number of issued shares of the trading partner company."The "total number of issued shares of the trading partner company" can be extracted from the company database 20. For example, the first emission quantity calculation unit 102 can use formula (2) to calculate the allocated emission quantity for category 15 of Scope 3 on a share basis. Allocated emission volume = emission volume of the trading partner company / total number of shares issued by the trading partner company × number of shares held by the reporting company

[0043] With further reference to Fig. 1, the second emission quantity calculation unit 103 calculates the total emission quantity. The total emission quantity is the total of the allocated emission quantities of all trading partner companies of the reporting company.

[0044] It is common for there to be many companies transacting with a single entity. Therefore, it is not realistic to calculate the allocated emissions for all trading partner entities, and it has been difficult for a reporting entity to calculate the total emissions.

[0045] To solve this problem, the information processing system 1 of the embodiment is configured to perform an “extension calculation” that can calculate an appropriate total emission amount using a sum of the allocated emission amounts calculated for the major trading partner enterprises, without calculating the allocated emission amounts for all trading partner enterprises.

[0046] Here, a method by which the second emission amount calculation unit 103 calculates the total emission amount using the “extension calculation” will be explained with reference to Fig. 6 to 8 are described in detail. Fig. 6 to 8 are diagrams for describing the processing performed by the information processing apparatus 10 of the embodiment.

[0047] Fig. Figure 6 shows an example as step 1, where the allocated emission quantities are calculated up to a point where the sum of procurement quantities exceeds a threshold th1 of the total procurement quantity. A procurement quantity here is a transaction quantity with the trading partner company. The total procurement quantity is the sum of the transaction quantities of all trading partner companies. The threshold th1 can be set arbitrarily, but is, for example, set to 70% or more of the total procurement quantity.

[0048] As in the example from Fig. 6, the total procurement quantity of the reporting company is 250 million yen and the total number of trading partner companies is 100. In this case, the second emission quantity calculation unit 103 calculates the threshold th1 based on the total procurement quantity. For example, the second emission quantity calculation unit 103 sets the threshold th1 to 175 million yen, which is 70% of the total procurement quantity of 250 million yen. For example, the second emission quantity calculation unit 103 records the procurement quantities of trading partner companies in descending order of procurement quantity and records the procurement quantities of the trading partner companies until the sum of the recorded procurement quantities exceeds the threshold th1. In the example from Fig. 6, the sum of the procurement quantities of five trading partner companies from Company A to Company E is 180 million yen, which exceeds the threshold th1 of 175 million yen.

[0049] Fig. Figure 7 shows an example as step 2, where the allocated emission quantities are calculated up to a point where the sum of the number of trading partner companies exceeds a threshold th2 of the total number of trading partners. The threshold th2 can be set arbitrarily, but is, for example, set at 7% or more of the total number of trading partners.

[0050] As in the examples from Fig. 6 and Fig. As shown in Figure 7, it is assumed that the total procurement quantity of the reporting companies is 250 million yen and the total number of trading partner companies is 100. In this case, the second emission quantity calculation unit 103 calculates the threshold th2 based on the total number of trading partners. For example, the second emission quantity calculation unit 103 sets the threshold th2 to seven companies, which is 7% of the total number of trading partners, 100. The second emission quantity calculation unit 103 records the procurement quantities of trading partner companies, for example, in descending order of procurement quantity, and records the procurement quantities of the trading partner companies until a sum of the number of trading partner companies whose procurement quantities were recorded exceeds the threshold th2. In the Fig. 6 and Fig. In the example shown in Figure 7, the procurement quantities of seven trading partner companies, from Company A to Company G, are recorded.

[0051] Here, the second emission quantity calculation unit 103 calculates variables for performing the "extension calculation." The variables for performing the "extension calculation" are an "extension ratio" and an "emission quantity before extension." Here, the "extension ratio" is a ratio of the sum of the procurement quantities recorded in steps 1 and 2 to the total procurement quantity. In the Fig. 6 and Fig. In the example shown in Figure 7, the "extension ratio" is 80%. The "emission quantity before extension" is the sum of the allocated emission quantities calculated based on the procurement quantities received from the trading partner companies in Step 1 and Step 2. In the example shown in Fig. 6 and Fig. In the example shown in Figure 7, the “emission quantity before extension” is 550 [t].

[0052] Fig. Figure 8 shows an example as step 3 in which the total emission amount is calculated using the "extension calculation." The second emission amount calculation unit 103 calculates the total emission amount using the "extension calculation" by dividing the "emission amount before extension" by the "extension ratio." In the Fig. In the example shown in Figure 8, the total emission quantity is calculated using the “extension calculation” to be 687.5 [t] by dividing the “emission quantity before extension” of 550 [t] by the “extension ratio” of 80 [%].

[0053] Fig. Fig. 9 is a diagram showing an example of an image displayed on the enterprise terminal 30 of the embodiment. For example, when a person in charge or the like of the reporting enterprise operates the enterprise terminal 30 to launch a calculation application or to access a URL for using the calculation service via a web browser or the like, an input screen such as the one shown in Fig. 9 shown, displayed.

[0054] As in Fig. As shown in Figure 9, for example, the input screen displays an area E1 labeled "Total CO2 Emission Amount," an area E2 labeled "Total Transaction Amount," an area E3 labeled "Trading Partner Companies," and a button labeled "Registration." The total transaction amount in the area E2, the company names and transaction amounts in the area E3, and the like are input, and the button labeled "Register" is pressed by a responsible person or the like of the reporting company, and data such as the total transaction amount, the company names, and the transaction amounts are transmitted to the information processing device 10.

[0055] The "total CO2 emission amount" calculated by the information processing device 10 is displayed in the E1 area. Here, the "total CO2 emission amount" is the total emission amount of the reporting company that meets a Scope 3 standard defined by an Effective Gas Protocol. The second emission amount calculation unit 103 calculates the total emission amount using "extension calculation" using the company names and a sum of the transaction amounts entered in the E3 area, as well as the total amount of the allocated emission amounts calculated by the first emission amount calculation unit 102, and the calculated total emission amount is displayed in the E1 area.

[0056] In area E2, the total transaction volume for the reporting entity is entered by a responsible person or equivalent of the reporting entity. The total transaction volume here is the total value of the transaction volumes with each of all trading partner entities with which the reporting entity has conducted transactions.

[0057] In the E3 area, the company name and transaction amount for each trading partner company are entered by a responsible person or the like of the reporting company. The E3 area also displays the allocated emission amount for each trading partner company calculated by the first emission amount calculation unit 102 (in Fig. 9, this is indicated as "CO2 emission quantity"). The first emission quantity calculation unit 102 calculates the allocated emission quantities by referring to the company database 20 based on the company names and transaction quantities entered in the area E3, and the calculated allocated emission quantities are displayed in the area E3.

[0058] Fig. 10 is a sequence diagram showing a flow of processing performed by the information processing system 1 of the embodiment. As shown in Fig. As shown in Figure 10, the company database 20 first accesses a platform for calculating the emission amount, such as a calculation application (step S10). Next, the information processing device 10 accesses the company terminal 30 and transmits information to the company terminal 30 on the input screen, as shown in Figure 10. Fig. 9 (step S11). As a result, the enterprise terminal 30 displays the input screen (step S12). The enterprise terminal 30 transmits the data by performing an input operation by a responsible person or the like of the reporting enterprise, a registration operation by pressing a button labeled "Register," and the like (step S13). The data here is necessary for calculating the allocated emission amount and the total emission amount, and is, for example, information indicating the transaction amounts between the reporting enterprise and the trading partner enterprise, or information indicating the number of shares of the trading partner enterprise held by the reporting enterprise.

[0059] The information processing device 10 acquires the data transmitted from the enterprise terminal 30 (step S14). Based on the acquired data, the information processing device 10 accesses the enterprise database 20 and calculates the allocated emission amount for each trading partner enterprise (step S15). The information processing device 10 also calculates the total emission amount by performing an extension calculation (step S16). The information processing device 10 transmits the allocated emission amount for each trading partner enterprise and the total emission amount to the enterprise terminal 30 (step S17). The enterprise terminal 30 displays the allocated emission amount for each trading partner enterprise and the total emission amount transmitted by the information processing device 10 (step S18).

[0060] Fig. 11 is a flowchart showing a flow of processing performed by the information processing apparatus 10 of the embodiment. Fig. Figure 11 shows a processing flow for calculating the allocated emission amount. First, the information processing device 10 acquires a Scope 3 category (step S20). The Scope 3 category is specified, for example, by the reporting company. In this case, an input screen as shown in Fig. 9, provided with an input field for entering a category. Alternatively, the category may also be defined according to a company name, industry, and the like of the trading partner, which are specified by the reporting company according to the input mask as shown in Fig. 9. In this case, the information processing device 10 stores in advance table information in which the Scope 3 category corresponds to the company name, industry, and the like of the trading partner company, and acquires the Scope 3 category by referring to the table information according to the company name, industry, and the like of the trading partner company input by the reported company.

[0061] The information processing device 10 then calculates the assigned emission amount according to the category.

[0062] When the category of Scope 3 is any of categories 1, 2, 4 and 9, the information processing device 10 records a transaction amount with the trading partner company by performing a data input according to the input screen as shown in Fig. 9 (step S21). Next, the information processing device 10 refers to the company database 20 based on the company name or the like of the trading partner company, which is displayed according to the input screen as shown in Fig. 9, and records the sales revenue and a GHG emission amount of the trading partner company (step S22). The information processing device 10 then calculates the allocated emission amount using the transaction amount with the trading partner company recorded in step S21 and the sales revenue and GHG emission amount of the trading partner company recorded in step S22 (step S23).

[0063] If the Scope 3 category is Category 15, the information processing device 10 determines whether the allocated emission amount is to be calculated on a monetary basis or on a share basis. For example, the information processing device 10 determines whether the allocated emission amount is to be calculated on a monetary basis or on a share basis using a method specified by the reporting entity.

[0064] When the allocated emission amount is calculated on a monetary basis, the information processing device 10 records an investment amount of the trading partner company in the reporting company by performing the data input according to the input screen as shown in Fig. 9 (step S25). Next, the information processing device 10 refers to the company database 20 based on the company name or the like of the trading partner company, which is displayed according to the input screen as shown in Fig. 9, and acquires a total asset amount and a GHG emission amount of the trading partner company (step S26). The information processing device 10 then calculates the allocated emission amount using the investment amount of the trading partner company in the reporting company acquired in step S25 and the total asset amount and GHG emission amount of the trading partner company acquired in step S26 (step S27).

[0065] When the allocated issue amount is calculated on a share basis, the information processing device 10 detects the number of shares of the trading partner company held by the reporting company by performing the data input according to the input screen as shown in Fig. 9 (step S28). Next, the information processing device 10 refers to the company database 20 based on the company name or the like of the trading partner company, which is displayed according to the input screen as shown in Fig. 9, and acquires the total number of issued shares and a GHG emission amount of the trading partner company (step S29). Then, the information processing device 10 calculates the allocated emission amount using the number of shares of the trading partner company held by the reporting company acquired in step S28 and the total number of issued shares and GHG emission amount of the trading partner company acquired in step S29 (step S30).

[0066] Fig. 12 is a flowchart showing the flow of processing performed by the information processing apparatus 10 of the embodiment. Fig. 12 shows a processing flow for calculating the total emission amount. First, the information processing device 10 acquires the total procurement amount and calculates the threshold value th1 based on the acquired total procurement amount (step S40). In addition, the information processing device 10 acquires the total number of trading partners and calculates the threshold value th2 based on the acquired total number of trading partners (step S41). The information processing device 10 acquires the total procurement amount and the total number of trading partners by processing the data input according to the input screen shown in Fig. 9 shown, recorded.

[0067] The information processing device 10 acquires the transaction amounts with the trading partner companies through the same processing as in step S21 (step S42). The information processing device 10 determines whether a sum of the transaction amounts acquired in step S42 has exceeded the threshold th1 (step S43), and if the threshold th1 has not been exceeded, returns to step S42 to acquire a transaction amount with another trading partner company different from the trading partner companies whose transaction amounts were acquired up to the previous time point. If the sum of the transaction amounts acquired in step S42 has exceeded the threshold th1, the information processing device 10 determines whether a sum of the number of trading partner companies whose transaction amounts were acquired in step S42 has exceeded the threshold th2 (step S44).If the threshold th2 has not been exceeded, the information processing device 10 returns to step S42 to acquire a transaction amount with another trading partner company that is different from the trading partner companies whose transaction amounts were acquired up to the previous point in time. If the threshold th2 has been exceeded, the information processing device 10 calculates the total emission amount using the extension calculation (step S45).

[0068] It should be noted that in the flowchart from Fig.12, an example was described in which it is determined whether both thresholds th1 and th2 have been exceeded. However, the present invention is not limited to this. For example, the information processing device 10 may only determine whether the threshold th1 has been exceeded, and if the threshold th1 has been exceeded, calculate the total emission amount using the extension calculation based on the sum of the transaction amounts already acquired and the sum of the number of trading partner companies whose transaction amounts have been acquired.

[0069] Alternatively, the information processing device 10 may only determine whether the threshold th2 has been exceeded, and if the threshold th2 has been exceeded, calculate the total emission amount using the extension calculation based on the sum of the transaction amounts already recorded and the sum of the number of trading partner enterprises whose transaction amounts have been recorded.

[0070] Furthermore, the information processing device 10 can calculate the total emission amount without performing the extension calculation. In this case, the information processing device 10 records the transaction amounts with all trading partner enterprises of the reporting enterprise and calculates the allocated emission amounts according to the recorded transaction amounts. The information processing device 10 does not set the sum of the calculated allocated emission amounts as the total emission amount based on the extension calculation. In cases such as when an enterprise does not have a large number of trading partner enterprises, it is possible to calculate the total emission amount with a realistic processing load even without performing the extension calculation.

[0071] As described above, the information processing system 1 of the embodiment includes the enterprise database 20, the acquisition unit 101, and the first emission amount calculation unit 102. The first emission amount calculation unit 102 is an example of the "emission amount calculation unit." The enterprise database 20 stores the enterprise information 201. The enterprise information 201 includes information indicating the sales volumes and greenhouse gas emission volumes of the enterprises. The acquisition unit 101 acquires the transaction volumes between the reporting enterprise and the trading partner enterprises. The first emission amount calculation unit 102 calculates the allocated emission amounts. The allocated emission amounts are the emission volumes of the trading partner enterprises allocated to the reporting enterprise.The first emission quantity calculation unit 102 calculates the assigned emission quantities using the sales quantities and greenhouse gas emission quantities of the trading partner companies stored in the company database 20 and the transaction quantities recorded by the recording unit 101.

[0072] As a result, the information processing system 1 of the embodiment can calculate the allocated emission amounts using the information indicating the sales volumes and greenhouse gas emission amounts of the enterprises stored in the enterprise database 20 and the transaction volumes with the trading partner enterprises, which are data of the reporting enterprise. This makes it possible to calculate the allocated emission amounts easily and without significant time and effort.

[0073] Furthermore, in the information processing system 1 of the embodiment, there are a plurality of categories corresponding to the content of transactions between the reporting company and the trading partner company. For example, there are 15 categories of Scope 3 defined by the Greenhouse Gas Protocol. The first emission amount calculation unit 102 calculates a divided value obtained by dividing the "emission amount (greenhouse gas emission amount) of the trading partner company" by the "sales revenue (sales amount) of the trading partner company" for at least one category among the plurality of categories. The first emission amount calculation unit 102 calculates a multiplied value as the allocated emission amount obtained by multiplying the divided value by the "transaction amount."For example, the first emission amount calculation unit 102 calculates a divided value obtained by dividing the "emission amount (greenhouse gas emission amount) of the trading partner company" by the "sales revenue (sales amount) of the trading partner company," and sets the calculated value as the allocated emission amount corresponding to at least one of categories 1, 2, 4, and 9 of a Scope 3 standard defined by the Greenhouse Gas Protocol. In this way, the information processing system 1 of the embodiment can easily calculate the allocated emission amount for at least one category.

[0074] Furthermore, the first emission amount calculation unit 102 in the information processing system 1 of the embodiment calculates a divided value obtained by dividing the "emission amount (greenhouse gas emission amount) of the trading partner enterprise" by the "total balance amount of the trading partner enterprise" in at least one of the plurality of categories. The first emission amount calculation unit 102 calculates a multiplied value as the allocated emission amount obtained by multiplying the divided value by the "investment amount of the reporting enterprise (in the trading partner enterprise)".For example, the first emission amount calculation unit 102 calculates a divided value obtained by dividing the "emission amount (greenhouse gas emission amount) of the trading partner company" by the "balance total amount of the trading partner company," and sets the calculated value as the allocated emission amount that meets at least Category 15 of the Scope 3 standard defined by the Greenhouse Gas Protocol. As a result, in the information processing system 1 of this embodiment, the allocated emission amount that meets at least one category can be easily calculated on a monetary basis.

[0075] Furthermore, the first emission amount calculation unit 102 in the information processing system 1 of the embodiment calculates a divided value obtained by dividing the "emission amount (greenhouse gas emission amount) of the trading partner enterprise" by the "total number of shares of the trading partner enterprise" in at least one of the plurality of categories. The first emission amount calculation unit 102 calculates a multiplied value obtained by multiplying the divided value by the "number of shares of the trading partner enterprise held by the reporting enterprise" as the allocated emission amount.For example, the first emission amount calculation unit 102 calculates a multiplied value obtained by multiplying the divided value obtained by dividing the "emission amount (greenhouse gas emission amount) of the trading partner company" by the "total number of shares of the trading partner company held by the reporting company," and sets the calculated value as the allocated emission amount that meets at least category 15 of the Scope 3 standards defined by the Greenhouse Gas Protocol. In this way, the information processing system 1 of the embodiment can easily calculate the allocated emission amount for at least one category on a share basis.

[0076] Furthermore, in the information processing system 1 of the embodiment, the acquisition unit 101 acquires the transaction amount with each trading partner enterprise such that the sum of the transaction amounts exceeds the threshold th1 (a first threshold) for the total procurement amount of the reporting enterprise. The second emission amount calculation unit 103 estimates the total amount of the allocated emission amounts of all the trading partner enterprises of the reporting enterprise based on the allocated emission amounts of the trading partner enterprises whose transaction amounts have been acquired, for example, through the renewal calculation. The second emission amount calculation unit 103 sets the estimated total amount as the total emission amount. The second emission amount calculation unit 103 is an example of an "emission amount calculation unit."As a result, in the information processing system 1 of the embodiment, it is possible to estimate the allocated emission amounts for all trading partner enterprises using transaction amounts that consider a certain ratio without using the transaction amounts with all trading partner enterprises, so that it is possible to easily calculate the total emission amount with high probability.

[0077] In addition, in the information processing system 1 of the embodiment, the acquisition unit 101 acquires the transaction volume of each trading partner enterprise so that the total number of trading partner enterprises whose transaction volumes have been acquired exceeds the threshold th2 (a second threshold) for the total number of trading partner enterprises of the reporting enterprise. The second emission volume calculation unit 103 estimates the total amount of the allocated emission volumes of all the trading partner enterprises of the reporting enterprise based on the allocated emission volumes of the trading partner enterprises whose transaction volumes have been acquired, for example, through the extension calculation. The second emission volume calculation unit 103 sets the estimated total amount as the total emission volume.As a result, in the information processing system 1 of the embodiment, it is possible to estimate the allocated emission amount for all the trading partner enterprises using the transaction amounts of a certain number of trading partner enterprises without using the transaction amounts with all the trading partner enterprises, so that it is possible to easily calculate the total emission amount with high probability.

[0078] Furthermore, in the information processing system 1 of the embodiment, the acquisition unit 101 acquires the transaction amount of each trading partner enterprise such that the sum of the transaction amounts exceeds the threshold th1 (a first threshold) for the total procurement amount of the reporting enterprise, and the total number of trading partner enterprises whose transaction amounts have been acquired exceeds the threshold th2 (a second threshold) for the total number of trading partner enterprises of the reporting enterprise. The second emission amount calculation unit 103 estimates the total allocated emission amount of all trading partner enterprises of the reporting enterprise based on the allocated emission amount of the trading partner enterprises whose transaction amounts have been acquired, for example, using the extension calculation.The second emission amount calculation unit 103 sets the estimated total amount as the total emission amount. As a result, in the information processing system 1 of the embodiment, it is possible to estimate the allocated emission amounts for all trading partner enterprises using transaction amounts that consider a specific ratio and the number of trading partner enterprises, without using the transaction amounts with all trading partner enterprises, thus making it possible to easily calculate the total emission amount with high probability.
