The emissions calculation unit 213 reads the emission intensity corresponding to the related company and product from the emission intensity storage unit 231, and multiplies the read emission intensity by the amount of activity of the related company (for example, the usage amount of the product used). It is possible to calculate the emissions related to the products used by related companies. The usage amount related to the calculation of emissions is obtained by the activity amount acquisition unit 212 as the activity amount (number of purchased products, etc.) of related companies obtained by accessing, for example, an accounting system, a sales management system, an inventory management system, etc. Alternatively, the activity amount acquisition unit 212 may receive the information from the information processing device 1 of the related company.

The emissions output unit 214 can output emissions for each related company. The emissions output unit 214 can output emissions for each related company and product used. The emissions output unit 214 can also output the emissions intensity for each related company. The emissions output unit 214 can output unit emissions for a plurality of related companies that provide the same product so that they can be compared. The emissions output unit 214 can output the emission intensity of a related company that provides a certain product and a related company that provides a substitute for the product so that they can be compared. Note that the emissions output unit 214 may also output the emissions intensity of related companies with which the company does not have transactions. In other words, it is also possible to output the emission intensity of other related companies that provide used products, related companies that provide substitute products, etc., so that they can be compared.

The company information acquisition unit 215 obtains the emissions and/or activity amount of the company. The company information acquisition unit 215 can receive input of emissions and/or activity amounts, for example. The company information acquisition unit 215 may calculate the amount of emissions using a well-known method. The company information acquisition unit 215 may obtain the amount of activity (such as the number of products sold by the company) from, for example, an accounting system, a sales management system, an inventory management system, or the like. The company information acquisition unit 215 can acquire emissions and/or activity amounts for each product. Further, the company information acquisition unit 215 obtains an amount calculated based on primary data among the company's emissions (referred to as company's primary data emissions). Among the company's direct or indirect emissions (Scope 1 and Scope 2), the company information acquisition unit 215 calculates, for example, Scope 2 emissions based on secondary data related to electricity charges. can calculate its own primary data emissions by excluding Scope 2 emissions related to electricity use from the total Scope 1 and Scope 2 emissions.

If the used product is used in multiple products, the company information acquisition unit 215 acquires the usage amount of the used product for each product (for example, from an accounting system, sales management system, inventory management system, etc.). ), the activity amount acquisition unit 212 calculates the activity amount of the used products for each product by apportioning the activity amount of the used products according to the usage amount of each product, and calculates the activity amount of the used products by product. 213 can calculate the amount of emissions related to the used product by the related company by multiplying the activity amount of the used product by the prorated product by the emission unit of the used product.

In addition, when the activity amount acquisition unit 212 collectively acquires the amount of activity related to multiple products used by an affiliated company, the company information acquisition unit 215 collects the amount of activity related to multiple products used by an affiliated company. By acquiring the usage amount used for each item (for example, it can be acquired from an accounting system, sales management system, inventory management system, etc.) and apportioning the amount of activity according to the usage amount of each product used, The emissions calculation unit 213 calculates the activity amount of the product and the product used corresponding to the product used, and the emission calculation unit 213 multiplies the activity amount corresponding to the product and the product used by the emission unit of the product used, and calculates the amount of activity of the product used by the related company. It is possible to calculate the amount of emissions related to

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

The emission unit transmission unit 217 can transmit the company's emission unit to another information processing device 1 (system of an affiliated company). The emission intensity transmitting unit 217 may transmit the company's emission intensity in response to a request from another information processing device 1, or may transmit the company's emission intensity periodically or every time the company's emission intensity is calculated. The basic unit may also be transmitted.

The data ratio output unit 218 can output the primary data ratio regarding the amount of 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 calculates, for each used product used in a certain product, the product of the emissions related to the used product multiplied by the primary data ratio of the used product (referred to as primary data emissions), Calculate the total amount of emissions based on primary data by adding the emissions (Scope 1 and 2) emitted by the company for the product in question and the calculated total of primary data emissions for all products used, The primary data ratio for the product can be calculated by dividing the calculated total value by the emissions amount for the product (total of scopes 1 to 3). For example, the data ratio output unit 218 acquires 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, and obtains the primary data corresponding to the company ID and the used product ID. The ratio is acquired from the emission intensity storage unit 231, and the emission amount of the product used (this may be a value obtained by multiplying the amount of use by the emission intensity, or the input of the emission amount may be accepted). The primary data emissions can be calculated by multiplying by the primary data ratio. In addition, if the emissions amount emitted by the company is calculated using secondary data, the data ratio output unit 218 adds only the company's primary data emissions amount to the total primary data emissions amount of the products used. be able to.

The emission intensity acquisition unit 211 can also acquire the amount of emissions emitted by an affiliated company that provides the used product for one or more products from the information processing device 1 of the affiliated company. In this case, the emission unit acquisition unit 211 can calculate the emission amount by product by apportioning the emission amount based on a predetermined standard. The emission unit acquisition unit 211 can apportion the emissions of a used product based on the production amount of the product, etc. for a plurality of products that use the same product. The emission intensity acquisition unit 211 can calculate the emission intensity for the products used by the related companies by dividing the emissions by product by the usage amount of the products used.

The product-specific emissions calculation unit 220 calculates emissions related to products (referred to as PCF (Product Carbon Footprint)). When the emission intensity acquisition unit 211 is able to obtain the emission intensity, the product-specific emissions calculation unit 220 calculates the first product-specific emissions for the used product by multiplying the emission intensity by the usage amount of the product used. can be calculated. If the emission intensity calculation unit 220 is unable to obtain the emission intensity and the emission intensity calculation unit 220 is able to obtain the emissions for all the products provided to the company, the product-specific emissions calculation unit 220 calculates the emissions based on a predetermined standard. The second product-specific emissions can be calculated by dividing the amount proportionally. The product-specific emissions calculation unit 220 calculates the first product-specific emissions (emissions accumulated using emission intensity) and the second product-specific emissions (emissions calculated by proportionally dividing the emissions of organizational units). amount) and the company's direct or indirect emissions (product-related emissions obtained by the company information acquisition unit 215), and calculate the total value as the activity amount (for example, product production amount). ) can be used to calculate the PCF.

FIG. 4 is a diagram illustrating the flow of processing for displaying the emission intensity for each related company.

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 obtain the emission intensity (S302: NO), the information processing device 1 obtains the amount of emissions related to all products used that are provided to the company from related companies (S303). If the amount of emissions can be obtained (S304: YES), the information processing device 1 divides the amount of emissions proportionally based on a predetermined standard (for example, the production amount of each of the company's products), and calculates the amount of emissions by product of the products used. is calculated (S305), and the emission intensity is calculated by dividing the emission amount by product by the usage amount of the product used (S306). On the other hand, if the amount of emissions could not be acquired (S304: NO), the information processing device 1 acquires secondary data related to the used product (S307). The information processing device 1 displays the emission intensity of each related company in a manner that allows comparison (S304). This makes it possible for companies to understand the emissions intensity of each affiliated company upstream or downstream in the supply chain, and to understand which affiliated companies are working to reduce greenhouse gas emissions. .

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

When the information processing device 1 acquires the emissions related to the entire products used that are provided to the company from related companies for each of the products used in the company's products (S321: YES), the information processing device 1 complies with a predetermined standard (for example, Calculate the emissions by product of the products used (S322) by apportioning the emissions by the production volume of each company's products (S322), and if the emissions are not obtained (S321: NO), the emissions intensity ( The amount of emissions for each product is calculated by multiplying the amount of use (primary data or secondary data) (S323). The information processing device 1 can calculate the PCF by summing the emissions by product (S324) and dividing the total emissions by the activity amount (production volume, sales volume, etc.) related to the product (S325). As a result, even if the emissions are calculated using the emission intensity determined by LCA (Life Cycle Assessment) etc. (emissions calculated using the stacking method), the emissions of the entire company can be divided by the number of products, sales, etc. Regardless of the determined emissions (emissions calculated using the proration method), the PCF can be calculated using available emissions.
