[0010] <System Overview> An information processing system according to one embodiment of the present invention will be described below. The information processing system of this embodiment is designed to estimate activity amounts from greenhouse gas emissions.

[0011] 1 is a diagram showing an example of the overall configuration of an information processing system. The information processing system of this embodiment is configured to include a management server 2. The management server 2 is communicably connected to a user terminal 1 via a communication network. 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.

[0012] The user terminal 1 is a computer operated by a user, and may be, for example, a smartphone, a tablet computer, or a personal computer.

[0013] The management server 2 may be a general-purpose computer such as a workstation or a personal computer, or may be logically realized by cloud computing.

[0014] <Administration Server> FIG. 2 is a diagram illustrating an example of the hardware configuration of the management server 2. Note that the illustrated configuration is an example, and other configurations may also be used. The management server 2 includes a CPU 201, a memory 202, a storage device 203, a communication interface 204, an input device 205, and an output device 206. The storage device 203 stores various data and programs, and is, for example, a hard disk drive, a solid state drive, or a flash memory. The communication interface 204 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, or a USB (Universal Serial Bus) connector or an RS232C connector for serial communication. The input device 205 is used to input data, and is, for example, a keyboard, a mouse, a touch panel, a button, a microphone, or the like. The output device 206 is used to output data, and is, for example, a display, a printer, a speaker, or the like. Each functional unit of the management server 2 described below is realized by the CPU 201 reading a program stored in the storage device 203 into the memory 202 and executing it, and each storage unit of the management server 2 is realized as part of the storage area provided by the memory 202 and the storage device 203.

[0015] 3 is a diagram showing an example of the software configuration of the management server 2. The management server 2 includes an emission coefficient storage unit 231, an emission amount acquisition unit 211, a ratio estimation unit 212, an activity amount estimation unit 213, an accounting data acquisition unit 214, a physical quantity conversion unit 215, and a validity determination unit 216.

[0016] <Storage section> The emission coefficient storage unit 231 stores emission coefficients for calculating greenhouse gas emissions. The emission coefficient storage unit 231 can store emission coefficients for each type of activity. The emission coefficient storage unit 231 can store emission coefficients for each business operator and type of activity.

[0017] <Functional section> The emission amount acquiring unit 211 acquires the amount of greenhouse gas emissions calculated in advance. For example, the emission amount acquiring unit 211 can acquire data from a report on greenhouse gas emissions published by a company. The emission amount acquiring unit 211 can acquire the amount of emissions related to the product (including services; the same applies below) to be analyzed from the user terminal 1. The emission amount acquiring unit 211 can acquire the amount of emissions related to the product to be analyzed (which may be a basic unit or the total amount of emissions related to the product from the company that provides the product).

[0018] The proportion estimation unit 212 estimates, for each type of activity for a product, the proportion of greenhouse gas emissions emitted by that activity to the total emissions emitted for that product (hereinafter referred to as the emission proportion). The proportion estimation unit 212 can estimate the type of activity performed for the product and the emission proportion.

[0019] The ratio estimation unit 212 can estimate the type of activity and the emission ratio according to the attributes of the product (such as the industry type, category, volume scale, sales scale, and country / region where the product is produced / provided).

[0020] For example, a ratio memory unit may be provided that stores the type of activity and the emission ratio associated with the activity in association with the attributes of the product, and the ratio estimation unit 212 may acquire the type of activity and the emission ratio corresponding to attributes that match or are similar to the attributes of the product being analyzed from the ratio memory unit.

[0021] Furthermore, the proportion estimation unit 212 can also estimate the type of activity and the emission proportion related to that activity by, for example, machine learning. For example, a learning model storage unit is provided that stores a learning model for inferring the type of activity and the proportion related to that activity, the learning model being created by machine learning using the attributes of a product, the type of activity related to that product, and the emission proportion related to that type of activity as training data, and the proportion estimation unit 212 can provide the attributes of the product to be analyzed to the learning model to estimate the type and proportion of the activity.

[0022] In addition, the proportion estimation unit 212 can also estimate the type of activity and the standard proportion related to the activity by providing a prompt to the large-scale language model that includes, for example, a description of the product and an instruction to output the standard type of activity for the product and the proportion of emissions by activity due to the standard activity (hereinafter referred to as emissions by type).

[0023] For example, when the report shows the amount of emissions by type, the ratio estimation unit 212 may calculate the amount of emissions themselves or the ratio of the amount of emissions to the total amount of emissions.

[0024] The activity amount estimation unit 213 estimates the activity amount from the emission amount. The activity amount estimation unit 213 can estimate the activity amount related to the emission of the emission amount by dividing the acquired emission amount by an emission coefficient. In cases where a predetermined percentage or more of the emission amount related to the product is due to one type of activity, the activity amount estimation unit 213 can estimate the activity amount by dividing the emission amount by an emission coefficient corresponding to the specific type of activity. Furthermore, the activity amount estimation unit 213 can calculate the emission amount by type for each type of activity based on the emission amount and the estimated percentage, and estimate the activity amount by type of activity (hereinafter referred to as the activity amount by type) by dividing the calculated emission amount by the emission coefficient corresponding to the type of activity.

[0025] The accounting data acquisition unit 214 acquires accounting data from an external accounting system. The accounting data includes amounts. The accounting data also includes items such as account titles, sub-titles, summaries, and notes. The accounting data acquisition unit 214 acquires accounting data about companies that have reported emissions acquired by the emissions acquisition unit 211. The accounting data acquisition unit 214 may, for example, receive accounting data from the user terminal 1, or may access an external accounting system and acquire data output by the accounting system using a scraping technique, or may access an API provided by the external accounting system to acquire accounting data.

[0026] The conversion unit (hereinafter referred to as physical quantity conversion unit) 215 converts the monetary amount included in the accounting data into a physical quantity. For example, the physical quantity conversion unit 215 can convert the unit of activity amount by dividing a gasoline purchase cost of 1 million yen by 100 (yen / liter) to convert it into 10,000 liters of gasoline.

[0027] The determination unit (hereinafter referred to as the validity determination unit) 216 supports the validity audit of the emission amount. The validity determination unit 216 determines whether the activity amount calculated back from the emission amount by the activity amount estimation unit 213 matches the activity amount of the accounting data. The validity determination unit 216 can determine whether the activity amount estimated by the activity amount estimation unit 213 is a correct value based on whether the difference between the activity amount estimated by the activity amount estimation unit 213 and the monetary amount of the accounting data is within a predetermined value. The validity determination unit 216 can also cause the physical quantity converter 215 to convert the unit of the monetary amount of the accounting data to match the unit of the activity amount calculated by the activity amount estimation unit 213. The validity determination unit 216 can determine whether the activity amount estimated by the activity amount estimation unit 213 is a correct value based on whether the difference between the activity amount calculated by the activity amount estimation unit 213 and the physical quantity converted by the physical quantity converter 215 is within a predetermined value.

[0028] <Operation> FIG. 4 is a diagram illustrating the operation of the management server 2.

[0029] The management server 2 acquires the emissions for each product (S301) and estimates the amount of activity by type related to the product (S302). As described above, the proportion of each activity type is estimated, the total emissions related to the product are multiplied by the proportion to determine the amount of emissions by type, and the determined emissions are divided by an emission coefficient to calculate the amount of activity by type. Furthermore, if the amount of emissions by type of activity is shown in a report or the like, the amount of activity by type of activity can also be calculated by dividing the emissions by the emission coefficient.

[0030] The management server 2 acquires the accounting data (S303), compares the amount of activity by category with the monetary amount included in the accounting data for each activity, and determines the legitimacy of the amount of emissions by category (S304). If the unit of the amount of activity by category is monetary, it can be directly compared with the monetary amount in the accounting data. If the unit of the amount of activity by category is not monetary, it can be converted into a physical amount that matches the unit of the amount of activity by category, and then the amount of activity by category can be compared with the physical amount.

[0031] The management server 2 outputs the legitimacy determination result (S305). The management server 2 can output the legitimacy determination result for each type of activity. Furthermore, if even one of the values ​​is not legitimate (for example, if the difference between the activity amount by type and the amount of accounting data or the converted physical quantity exceeds a predetermined value), the management server 2 may determine that the emissions amount for the product as a whole is not legitimate, and output the determination result.

[0032] As described above, according to the information processing system of this embodiment, the amount of activity can be estimated from the amount of emissions.

[0033] Although the present embodiment has been described above, the above embodiment is intended to facilitate understanding of the present invention and is not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit thereof, and equivalents thereof are also included in the present invention.

[0034] For example, the processing by each of the functional units of the management server 2 described above may be performed by any of the functional units. Also, a different functional unit that performs part of the processing by each of the functional units described above may be added. Also, the functional units of the management server 2 may be distributed across multiple computers.

[0035] Furthermore, the information stored in each storage unit of the management server may be stored in any of the storage units. That is, the information stored in the above-mentioned multiple storage units may be stored in one storage unit, or part of the information stored in one of the above-mentioned storage units may be stored in another storage unit.

[0036] In this embodiment, the physical quantity conversion unit 215 converts the monetary amount of the accounting data into a physical quantity, but the physical quantity conversion unit 215 may also convert the activity amount into a monetary amount. In this case, the validity can be determined based on whether the difference between the result of converting the activity amount by category into a monetary unit and the monetary amount of the accounting data is equal to or less than a predetermined value.

[0037] Furthermore, although the activity amount is estimated for each product in this embodiment, the activity amount related to a company may be estimated. In this case, the activity amount may be estimated for each company instead of for each product. In this case, for example, a company proportion storage unit may be provided that stores the type of activity and the emission ratio of the emissions emitted by the activity to the total emissions by the company in association with the attributes of the company (such as the type of industry, sales volume, production volume, floor area, and number of employees), and the ratio estimation unit 212 can acquire the type of activity and the emission ratio corresponding to attributes that match or are similar to the attributes of the company to be analyzed from the company proportion storage unit.
