[0010] <System Overview> FIG. 1 is a diagram showing an example of the overall configuration of an information processing system according to one embodiment of the present invention. The information processing system of this embodiment includes an information processing device 1. The information processing device 1 is communicably connected to another information processing device 1 via a communication network. The example of FIG. 1 shows two information processing devices 1 (1) and (2) communicably connected to each other. The communication network is, for example, the Internet, and is constructed using a public telephone line network, a mobile phone line network, a wireless communication path, Ethernet (registered trademark), etc.

[0011] The information processing device 1 is a computer that outputs greenhouse gas emission status (emission coefficient (emissions intensity), activity amount, and emission amount). The greenhouse gas emissions of a company can be calculated by multiplying the activity amount of the company (for example, the number of products produced) by the emission intensity of the company. The information processing device 1 can also transmit its own emission intensity (which may include activity amount and emission amount) to other information processing devices 1, and can obtain other people's emission intensity from the other information processing devices 1. This makes it possible to calculate emissions for the entire supply chain, including the company itself.

[0012] In this embodiment, each company exchanges the emission intensity (primary data) calculated for its own company, allowing for the calculation of more realistic emissions.

[0013] The information processing device 1 may be a general-purpose computer such as a workstation or a personal computer, or may be logically realized by cloud computing.

[0014] <Information processing device 1> FIG. 2 is a diagram illustrating an example of the hardware configuration of the information processing device 1. Note that the illustrated configuration is an example, and other configurations may also be used. The information processing device 1 includes a CPU 101, a memory 102, a storage device 103, a communication interface 104, an input device 105, and an output device 106. The storage device 103 stores various data and programs, and is, for example, a hard disk drive, a solid state drive, or a flash memory. The communication interface 104 is an interface for connecting to a communication network, and is, for example, an adapter for connecting to Ethernet (registered trademark), a modem for connecting to a public telephone network, a wireless communication device for wireless communication, a USB (Universal Serial Bus) connector or an RS232C connector for serial communication, etc. The input device 105 is, for example, a keyboard, a mouse, a touch panel, a button, a microphone, etc. for inputting data. The output device 106 is, for example, a display, a printer, a speaker, etc. for outputting data. Each functional unit of the information processing device 1 described below is realized by the CPU 101 reading a program stored in the storage device 103 into the memory 102 and executing it, and each storage unit of the information processing device 1 is realized as part of the storage area provided by the memory 102 and the storage device 103.

[0015] 3 is a diagram showing an example of the software configuration of the information processing device 1. The information processing device 1 includes an emission intensity unit storage unit 231, a product information storage unit 232, a used product information storage unit 233, an emission intensity unit acquisition unit 211, an activity amount acquisition unit 212, an emission amount calculation unit 213, an emission amount output unit 214, a company information acquisition unit 215, an emission intensity unit calculation unit 216, an emission intensity unit transmission unit 217, a data ratio output unit 218, and a product-specific emission amount calculation unit 220.

[0016] The emission intensity memory unit 231 stores coefficients (called emission intensity units) for calculating greenhouse gas emissions in association with companies. The emission intensity memory unit 231 can store emission intensity units and primary data ratios in association with company IDs indicating companies and product IDs indicating products (including services; the same applies below) provided by companies. Primary data is data collected by the companies themselves, obtained from direct measurements, or obtained from calculations based on direct measurements at the initial information source. Data other than primary data is secondary data. For example, secondary data is data that has been standardized (statistically processed) from emissions from multiple companies that provide the same type of product. The primary data ratio is the proportion of emissions calculated using primary data to the total amount of calculated emissions.

[0017] The product information storage unit 232 stores information about products (product information). The product information can include various information about the product, such as the product name, in association with a product ID that indicates the product. The product information storage unit 232 is assumed to register product information about all products that the company provides to other companies.

[0018] The used product information storage unit 233 stores information (used product information) about other products (hereinafter referred to as used products) used to provide the product. The used products are, for example, raw materials used to produce the product. The used product information can include a product ID indicating the product, a used product ID indicating the used product, a company ID indicating the company that provides the used product, and the amount of used product used for one product (usage amount).

[0019] The emission intensity acquisition unit 211 acquires emission intensity units calculated by companies (affiliated companies) that are at least either upstream or downstream in the supply chain. Affiliated companies are companies that provide products in categories defined in Scope 3 of the GHG Protocol. The emission intensity acquisition unit 211 may accept input of emission intensity units from a user, but in this embodiment, it acquires the emission intensity units from another information processing device 1. The information processing device 1 can provide a primary data ratio along with the emission intensity units. The emission intensity acquisition unit 211 can update the emission intensity unit storage unit 231 with the acquired emission intensity units and primary data ratio. The emission intensity unit acquisition unit 211 can update the emission intensity units and primary data ratio corresponding to the company ID indicating the affiliated company related to the other information processing device 1 that is the source of the emission intensity units and the product ID indicating the product purchased from the affiliated company to the acquired ones. When the emission intensity units of the secondary data are registered in the emission intensity unit storage unit 231, the emission intensity acquisition unit 211 can set the primary data ratio to "0".

[0020] The activity amount acquisition unit 212 acquires an activity amount related to products used by an associated company. The activity amount can be the amount of products provided by an associated company, such as the number of products, the amount of energy, or the distance traveled by logistics. The activity amount acquisition unit 212 can acquire the activity amount related to an associated company from the information processing device 1 of the associated company. The activity amount acquisition unit 212 may be configured to accept input of the activity amount of an associated company from the user. Furthermore, the activity amount acquisition unit 212 may access, for example, an accounting system, a sales management system, an inventory management system, or the like, and acquire the number (amount) of products purchased from an associated company as the activity amount.

[0021] The emission calculation unit 213 reads out the emission intensity units corresponding to the related company and product from the emission intensity unit storage unit 231, and multiplies the activity amount of the related company (for example, the usage amount of the product) by the read emission intensity unit, thereby calculating the emission amount related to the product used by the related company. The usage amount used in calculating the emission amount may be the activity amount of the related company (such as the number of products purchased) obtained by the activity amount acquisition unit 212 by accessing, for example, an accounting system, a sales management system, an inventory management system, etc., or may be received by the activity amount acquisition unit 212 from the information processing device 1 of the related company.

[0022] The emission output unit 214 can output the emission amount for each associated company. The emission output unit 214 can output the emission amount for each associated company and each product used. The emission output unit 214 can also output the emission intensity for each associated company. The emission output unit 214 can output the emission intensity for multiple associated companies that provide the same product in a manner that allows them to be compared. The emission output unit 214 can output the emission intensity for an associated company that provides a certain product and an associated company that provides a substitute for that product in a manner that allows them to be compared. Note that the emission output unit 214 may also output the emission intensity for associated companies with which there is no transaction. In other words, it can also output the emission intensity for associated companies that are other providers of the products used, associated companies that provide substitutes, etc. in a manner that allows them to be compared.

[0023] The company information acquisition unit 215 acquires the company's emissions and / or activity amounts. The company information acquisition unit 215 can, for example, accept input of emissions and / or activity amounts. The company information acquisition unit 215 may calculate emissions using a well-known method. The company information acquisition unit 215 may acquire activity amounts (such as the number of company products sold) from, for example, an accounting system, a sales management system, or an inventory management system. The company information acquisition unit 215 can acquire emissions and / or activity amounts for each product. In addition, the company information acquisition unit 215 acquires the amount of the company's emissions calculated based on primary data (referred to as company primary data emissions). Of the company's direct or indirect emissions (scope 1 and scope 2), for example, if scope 2 emissions are calculated based on secondary data related to electricity charges, the company information acquisition unit 215 can calculate the company's primary data emissions by excluding the emissions related to Scope 2 electricity use from the total emissions of Scope 1 and Scope 2.

[0024] When a used product is used in multiple products, the company information acquisition unit 215 acquires the usage amount of the used product used for each product (for example, this can be acquired from an accounting system, sales management system, inventory management system, etc.), the activity amount acquisition unit 212 calculates the activity amount of the used product for each product by apportioning the activity amount of the used product according to the usage amount for each product, and the emission calculation unit 213 multiplies the apportioned activity amount of the used product for each product by the emission unit of the used product to calculate the emission amount related to the used product by the related company.

[0025] Furthermore, when the activity amount acquisition unit 212 acquires the activity amounts related to multiple products used by an associated company collectively, the company information acquisition unit 215 acquires the usage amount used for the multiple products used procured from the associated company (for example, this can be acquired from an accounting system, sales management system, inventory management system, etc.), and calculates the activity amount of the products and the products used corresponding to the products used by allocating the activity amount according to the usage amount of each of the acquired products used, and the emission calculation unit 213 can calculate the emissions related to the products used by the associated company by multiplying the activity amount corresponding to the products and the products used by the emission unit of the products used.

[0026] The emission intensity calculation unit 216 calculates the company's emission intensity, which is the company's emission intensity, based on the company's acquired emission amount and activity amount.

[0027] The emission intensity unit transmission unit 217 can transmit the company's emission intensity unit to other information processing devices 1 (systems of related companies). The emission intensity unit transmission unit 217 may transmit the company's emission intensity unit in response to a request from other information processing devices 1, or may transmit the company's emission intensity unit periodically or every time the company's emission intensity unit is calculated.

[0028] The data ratio output unit 218 can output the primary data ratio related to the emissions related to the company's products. The data ratio output unit 218 can calculate the primary data ratio. For example, the data ratio output unit 218 can calculate the amount of emissions related to each product used in a certain product by multiplying the emissions related to the product used by the primary data ratio of the product used (referred to as primary data emissions), add the emissions emitted by the company for the product (Scopes 1 and 2) to the total of the calculated primary data emissions for all products used to calculate the total amount of emissions based on the primary data, and divide the calculated total by the emissions related to the product (total of Scopes 1 to 3) to calculate the primary data ratio for the product. The data ratio output unit 218 can, for example, acquire the used product ID, usage amount, and company ID corresponding to the product ID indicating the company's product from the used product information storage unit 233, acquire the primary data ratio corresponding to the company ID and used product ID from the emission intensity storage unit 231, and calculate the primary data emissions by multiplying the emissions of the used product (which may be a value obtained by multiplying the usage amount by the emission intensity, or may be configured to accept input of the emissions) by the primary data ratio. Furthermore, when the data ratio output unit 218 calculates the emissions emitted by the company using secondary data, it can add only the company's primary data emissions to the total primary data emissions of the used products.

[0029] The emission intensity acquisition unit 211 can also acquire, for a product used in one or more products, the emissions emitted by an associated company that provides the product from the information processing device 1 of the associated company. In this case, the emission intensity acquisition unit 211 can calculate the emission amount for each product by apportioning the emissions according to a predetermined standard. For multiple products that use the same product, the emission intensity acquisition unit 211 can apportion the emissions of the product used based on the production volume of the product, etc. The emission intensity acquisition unit 211 can calculate the emission intensity for the product used by the associated company by dividing the emission amount for each product by the usage amount of the product.

[0030] The product-specific emission calculation unit 220 calculates the emissions related to the products (called PCF (Product Carbon Footprint)). If the emission intensity acquisition unit 211 is able to acquire the emission intensity, the product-specific emission calculation unit 220 can calculate the first product-specific emission related to the used product by multiplying the emission intensity by the amount of the used product. If the emission intensity acquisition unit 211 is unable to acquire the emission intensity but is able to acquire the emissions related to all used products provided to the company, the product-specific emission calculation unit 220 can calculate the second product-specific emission by apportioning the emissions according to a predetermined standard. The product-specific emission calculation unit 220 can calculate the total value of the first product-specific emission (emissions accumulated using the emission intensity), the second product-specific emission (emissions calculated by apportioning the emissions per organization), and the company's direct or indirect emission (emissions related to products among the emissions acquired by the company information acquisition unit 215), and divide the calculated total value by the activity amount (e.g., the production volume of the product).

[0031] <Operation> FIG. 4 is a diagram illustrating the flow of processing for displaying the emission intensity for each associated company.

[0032] The information processing device 1 acquires the emission intensity from the information processing device 1 of the related company (S301). If the information processing device 1 is unable to acquire the emission intensity (S302: NO), it acquires the emission amount for all the used products provided to the company by the related company (S303). If the emission amount is acquired (S304: YES), the information processing device 1 calculates the emission amount for each used product by apportioning the emission amount based on a predetermined standard (e.g., the production volume of each of the company's products) (S305), and calculates the emission intensity by dividing the emission amount for each product by the usage amount of the used product (S306). On the other hand, if the information processing device 1 is unable to acquire the emission amount (S304: NO), it acquires secondary data for the used products (S307). The information processing device 1 displays the emission intensity for each related company in a comparable manner (S304). This allows the company to understand the emission intensity for each related company upstream or downstream in the supply chain and to identify related companies that are working to reduce greenhouse gas emissions.

[0033] FIG. 5 is a diagram illustrating the flow of processing for calculating the PCF.

[0034] If the information processing device 1 obtains the emissions for all products used in the company's products provided to the company by related companies (S321: YES), it calculates the emissions for each product by apportioning the emissions based on a predetermined standard (e.g., the production volume of each of the company's products) (S322). If the information processing device 1 does not obtain the emissions (S321: NO), it calculates the emissions for each product by multiplying the emissions intensity (primary data or secondary data) by the usage amount (S323). The information processing device 1 sums the emissions for each product (S324) and divides the sum by the activity amount related to the product (production volume, sales volume, etc.) to calculate the PCF (S325). This makes it possible to calculate the PCF using available data, whether it is emissions calculated using an emissions intensity determined by LCA (Life Cycle Assessment) or the like (e.g., emissions calculated using the cumulative method) or emissions calculated by dividing the company's total emissions by the number of products, sales, etc. (e.g., emissions calculated using the apportionment method).
