FIG. 2 is a diagram illustrating the operation of the information processing system.

<System Overview>
An information processing system according to one embodiment of the present invention will be described below. The information processing system according to this embodiment supports the formulation of emission reduction targets, particularly for Scope 3 of the GHG Protocol. Scope 3 emissions are greenhouse gas emissions by business entities (hereinafter referred to as suppliers) that are upstream and/or downstream in the supply chain of a business entity whose emissions are to be calculated. The information processing system according to this embodiment incorporates the supplier's reduction target and proposes it as a candidate for the company's own Scope 3 emission reduction target.

Figure 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 a management server 2. The management server 2 is communicatively connected to a user terminal 1 via a communication network 3. The communication network 3 is, for example, the Internet, and is constructed using a public telephone network, a mobile phone network, a wireless communication path, Ethernet (registered trademark), or the like.

User terminal 1 is a computer operated by a user of a business entity, such as a company, that is the waste generator. User terminal 1 can be, for example, a smartphone, tablet computer, or personal computer. The user can use user terminal 1 to access management server 2 and calculate waste emissions.

The management server 2 is a computer that calculates and manages emissions. The management server 2 may be a general-purpose computer such as a workstation or personal computer, or may be logically realized using cloud computing.

<Management 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, memory 202, storage device 203, communication interface 204, input device 205, and output device 206. The storage device 203 stores various data and programs, and is, for example, a hard disk drive, solid state drive, or flash memory. The communication interface 204 is an interface for connecting to the communication network 3, 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 205 is used to input data, and is, for example, a keyboard, mouse, touch panel, button, microphone, etc. The output device 206 is used to output data, and is, for example, a display, printer, speaker, etc. 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.

Figure 3 shows an example software configuration of the management server 2. Note that the illustrated configuration is an example, and other configurations may be used. The management server 2 includes an emission amount memory unit 231, a target memory unit 232, a target acquisition unit 211, an estimation unit 212, and a calculation unit 213.

The emission amount storage unit 231 stores information specifying the amount of greenhouse gas emissions for each supplier. In this embodiment, the emission amount storage unit 231 stores the activity amount and emission intensity as information specifying the emission amount, but it may also store the emission amount itself. The emission amount storage unit 231 can store a company ID indicating the supplier, time information, information for specifying the activity by the supplier (activity content), the activity amount and emission intensity related to the activity. The time information may be, for example, a year. The time information can also be the year/month, or the year/month/day, etc.

The emissions storage unit 231 can further store information identifying the company's direct and indirect emissions (emissions related to Scopes 1 and 2). The emissions storage unit 231 may store the emissions themselves as information identifying the company's emissions related to Scopes 1 and 2, or it may store the activity amount and emission coefficient.

The target memory unit 232 stores a target reduction rate for each supplier. The target reduction rate is a target set by the supplier and is a ratio to the supplier's emissions in the base year. The target memory unit 232 stores the base point in time, the target point in time, and the reduction rate in association with the company ID that identifies the supplier and the activity content that identifies the supplier's activities. The base point in time and the target point in time may be specified by year, or by year/month, date, date, etc., for example.

The target acquisition unit 211 acquires the target reduction rate from the supplier. The target acquisition unit 211 can, for example, send a request to the supplier's user and receive the target reduction rate from the supplier's user terminal 1. The target acquisition unit 211 may acquire the target reduction rate from a server on which the target reduction rate is managed, or may acquire the target reduction rate disclosed by the supplier from, for example, the supplier's web page or a newspaper company's web page. The target acquisition unit 211 can acquire the activity content, base year, target year, and reduction rate. The target acquisition unit 211 can register the acquired target reduction rate in the target memory unit 232.

The target acquisition unit 211 can also acquire the target reduction rate (company reduction rate) related to the company's emissions. The target acquisition unit 211 can receive the company reduction rate from the user terminal 1.

The estimation unit 212 estimates future emissions for each supplier. The estimation unit 212 can calculate emissions at the target point in time by multiplying the supplier's emissions at the base point in time (the value obtained by multiplying the activity amount by the emissions intensity) by the target reduction rate.

For suppliers for which the target reduction rate could not be obtained, the estimation unit 212 can estimate future emissions by using the statistical value of the target reduction rate stored in the target memory unit 232 as the target reduction rate for that supplier. For example, the estimation unit 212 can use the average of the target reduction rates of all suppliers as the target reduction rate for a supplier for which the target reduction rate could not be obtained.

Calculation unit 213 calculates the target reduction rate for emissions related to Scope 3. Calculation unit 213 can calculate the reduction rate (the ratio of the value obtained by subtracting the second total from the first total to the first total) by comparing a first total of future emissions estimated for each supplier with a second total of emissions for each supplier at the base time.

The calculation unit 213 can similarly calculate the reduction rate for each category in Scope 3.

Calculation unit 213 can also calculate the reduction rate (carbon footprint: CFP reduction rate) for the total of Scopes 1 to 3. Calculation unit 213 calculates the company's future emissions (at the target point in time) based on the company's emissions and its reduction rate, calculates a first total of the emissions for the company and its suppliers at the target point in time, and a second total of the emissions for the company and its suppliers at the base point in time, and calculates the ratio of the difference between the first and second totals to the second total as the reduction rate for Scopes 1 to 3.

<Operation>
FIG. 4 is a diagram illustrating the operation of the information processing system.

The management server 2 acquires reduction targets (reduction rates from the base point to the target point) from suppliers (S301). For example, the management server 2 can send a request to the supplier's user and receive the reduction targets from the supplier's user's user terminal 1. The management server 2 acquires the emissions related to the supplier's activities at the base point in time from the emissions storage unit 231, and calculates the reduction target amount up to the target point in time by multiplying the acquired emissions by the reduction rate (S302). The management server 2 calculates the reduction target amount for Scope 3 by adding up the reduction target amounts calculated for each supplier (S303). Note that for suppliers for which the management server 2 was unable to acquire reduction targets, it can calculate the reduction target amount using statistics (such as the average reduction rate) of the reduction targets of other suppliers in Scope 3 or other suppliers in the same category in Scope 3.

The management server 2 can calculate the total supplier emissions at the base point in time (i.e., the Scope 3 emissions at the base point in time) and calculate the ratio of the Scope 3 reduction target to that total as the Scope 3 target reduction rate (S304).

The management server 2 acquires the company's reduction targets for Scopes 1 and 2 (S305). For example, the management server 2 can acquire the company's reduction targets and calculate the reduction target amount up to the target point in time by multiplying the company's emissions at the base point in time by the reduction rate. The company's reduction targets can be obtained, for example, by sending a request to the company's users and receiving the reduction targets from the company's users' user terminals 1.

The management server 2 obtains the company's emissions related to Scopes 1 and 2 from the emissions storage unit 231, and multiplies the obtained emissions (total) by the reduction rate to calculate the reduction target amounts for Scopes 1 and 2 up to the target time point (S306).

The management server 2 totals the reduction target amounts for scopes 1-3 (S307), calculates the total emissions related to scopes 1-3 at the base point in time from the emissions storage unit 231, and calculates the ratio of the total reduction target amounts for scopes 1-3 to the calculated emissions for scopes 1-3 at the base point in time as the company's target reduction rate (S308).

The management server 2 can output the reduction target (target reduction rate) for Scope 3 and the reduction target (target reduction rate) for Scopes 1-3 (carbon footprint; CFP) (S309).

As described above, the information processing system of this embodiment can automatically calculate a company's Scope 3 reduction targets and its carbon footprint reduction targets based on the reduction targets collected from suppliers.

The present embodiment has been described above, but 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 its spirit, and equivalents thereof are also included within the present invention.
