[0009] [Figure 1] 1 is a diagram illustrating an example of the overall configuration of an information processing system according to an embodiment of the present invention. [Figure 2] FIG. 2 illustrates an example of a hardware configuration of a management server 2. [Figure 3] FIG. 2 illustrates an example of the software configuration of a management server 2. [Figure 4] FIG. 2 is a diagram illustrating the operation of the information processing system. DETAILED DESCRIPTION OF THE INVENTION

[0010] <System Overview> 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 is configured to include a management server 2. The management server 2 is communicably connected to a user device 1 via a communication network. The communication network is, for example, the Internet, and is constructed using a public telephone network, a mobile phone network, a wireless communication path, Ethernet (registered trademark), etc.

[0011] The user device 1 is a computer operated by a user of a business entity such as a company that generates waste. The user device 1 may be, for example, a smartphone, a tablet computer, or a personal computer.

[0012] 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 a personal computer, or may be logically realized by cloud computing.

[0013] <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, for example, a keyboard, a mouse, a touch panel, a button, a microphone, or the like for inputting data. The output device 206 is, for example, a display, a printer, a speaker, or the like for outputting data. 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.

[0014] 3 is a diagram showing an example of the software configuration of the management server 2. Note that the configuration shown in the figure is an example, and other configurations may be used. The management server 2 includes a model storage unit 231, a business entity information storage unit 232, an emission amount storage unit 233, an emission amount calculation unit 211, an attribute value acquisition unit 212, an estimation unit 213, and an output unit 214.

[0015] The model storage unit 231 stores an estimation model for estimating the amount of greenhouse gas emissions by a business entity based on the attributes of the business entity. The estimation model is created by analyzing the relationship between attribute values ​​related to the attributes of a base where greenhouse gases are emitted and the amount of greenhouse gas emissions. The estimation model is, for example, a statistical model that analyzes the correlation between attribute values ​​and emissions. In this embodiment, the attribute values ​​are assumed to be the floor area of ​​the base. Therefore, the estimation model may be expressed, for example, by a formula that multiplies the amount of emissions per unit area of ​​the base by the floor area. The estimation model may be created by machine learning using the attribute values ​​as input data and the emissions as training data. Furthermore, the attribute values ​​may include the type of base (the type of activity at the base). In this embodiment, the model storage unit 231 can store an estimation model for each type of base in association with the business entity. The type of base may be the type of business (the type of activity) conducted at the base. The type of base may be, for example, an office, a factory, a staffed store, an unmanned store with an automatic teller machine, etc. The estimation model may be a model that estimates emissions given both floor area and activity type as feature quantities. The attribute values ​​may also include the business entity's industry. The model storage unit 231 may store estimation models, for example, in association with the business entity's industry and the type of base. The estimation model may also be a model that estimates emissions given the industry, base type, and floor area. In addition to or instead of floor area, attribute values ​​may also be used, for example, the volume of the base building, the height of the base building, the location of the base (region, prefecture, city, ward, town, village, latitude, longitude, etc.), the department that uses the base, etc.

[0016] The business entity information storage unit 232 stores information about business entities (hereinafter referred to as business entity information). The business entity information may include the business entity's industry in association with information identifying the business entity (business entity ID). The business entity information may also include the business entity's sales volume, asset size, number of bases, etc.

[0017] The emission amount storage unit 233 stores the greenhouse gas emissions by the business entity. The emission amount storage unit 233 can store the scope, category, and emission amount in association with the business entity ID indicating the business entity and time information. For Scopes 1 and 2, the category does not need to be registered.

[0018] The emission calculation unit 211 calculates the amount of greenhouse gas emissions by the business entity. The emission calculation unit 211 can calculate the amount of emissions by, for example, acquiring the amount of activity by the business entity and multiplying it by a predetermined emission coefficient. The emission calculation unit 211 can calculate the amount of emissions for each base. Note that known methods can be used for calculating the amount of emissions by the emission calculation unit 211, and detailed explanations will be omitted here. The emission amounts calculated by the emission calculation unit 211 are registered in the emission storage unit 233. For bases for which the amount of activity cannot be acquired, the emission amount is estimated by the estimation unit 213, which will be described later.

[0019] The attribute value acquisition unit 212 acquires attribute values ​​related to the attributes of the base. The attribute value acquisition unit 212 can acquire attribute values ​​for each base. The attribute value acquisition unit 212 may be configured to acquire attribute values ​​only for bases whose emissions are unknown. The attribute value acquisition unit 212 can acquire the type of base and attribute values ​​other than the type. In this embodiment, the attribute value acquisition unit 212 acquires the type of base and the floor area of ​​the base. The attribute value acquisition unit 212 can receive, for example, attribute values ​​input by the user device 1. An attribute value storage unit that stores attribute values ​​for each base may be provided, and the attribute value acquisition unit 212 may read out the attribute values ​​from the attribute value storage unit.

[0020] The estimation unit 213 estimates the amount of greenhouse gas emissions at the base. The estimation unit 213 estimates the amount of emissions for a base for which the emission amount could not be calculated by the emission calculation unit 211 (for example, the amount of activity could not be acquired). The estimation unit 213 can estimate the amount of emissions by providing the attribute values ​​acquired by the attribute value acquisition unit 212 to an estimation model stored in the model storage unit 231. The estimation unit 213 can estimate the amount of emissions by providing the acquired attribute values ​​to an estimation model corresponding to the acquired type of base. In this embodiment, the estimation unit 213 estimates the amount of emissions by providing the acquired floor area to the business entity to which the user belongs and the estimation model corresponding to the acquired type of base.

[0021] If an estimation model corresponding to the business entity to which the user belongs is not registered in the model storage unit 231, the estimation unit 213 may estimate emissions using an estimation model corresponding to another business entity in the same industry as the business entity. In this case, the estimation unit 213 can refer to the business entity information storage unit 232 to identify the industry of the business entity to which the user belongs and identify other business entities in the same industry as the identified industry. In this case, the estimation unit 213 may also acquire the industry, sales volume, asset size, or number of locations of the business entity to which the user belongs, or a combination of at least two or more of these, and identify other business entities corresponding to the acquired information. Note that an identification unit different from the estimation unit 213 may be provided to identify the business entity and the business entity's industry.

[0022] The output unit 214 outputs the greenhouse gas emissions by the business entity. For example, the output unit 214 can output the emissions calculated by the emission amount calculation unit 211 and the emissions estimated by the estimation unit 213 separately. The output unit 214 may output the emissions in a report format such as a report for the Energy Saving Act.

[0023] <Operation> FIG. 4 is a diagram illustrating the operation of the information processing system.

[0024] The management server 2 calculates the amount of emissions for each base (S301), and for bases for which the amount of emissions could not be calculated, obtains the type and floor area of ​​the base (S302), estimates the amount of emissions by inputting the floor area into an estimation model corresponding to the type of base received (S303), and registers the calculated amount of emissions and the estimated amount of emissions (S304).

[0025] As described above, according to the information processing system of this embodiment, even for bases for which it is difficult to calculate the amount of emissions, it is possible to estimate the amount of emissions from the attributes of the bases.

[0026] <Modification> In the above-described embodiment, an estimation model is stored for each type of base, but a value representing the type or a dummy value may be given to the estimation model as a feature.

[0027] Furthermore, in the above-described embodiment, the discharge amount is estimated, but the amount of activity may be estimated.

[0028] In this case, the model storage unit 231 can store, instead of or in addition to the estimation model that estimates the emission amount, an estimation model that estimates the activity amount from the attributes of the base, which is created by analyzing the relationship between the attributes of the base (e.g., type and floor area) and the actual value of the activity amount at the base. A value representing the type or a dummy value may be provided as a feature to the estimation model.

[0029] The management server 2 also includes an activity amount storage unit (not shown) that stores the activity amount. The activity amount storage unit can store the activity amount in association with a business entity ID that indicates a business entity, a base ID that identifies a base, time information, a scope, and a category.

[0030] The estimation unit 213 can receive attribute values ​​(e.g., type and floor area) of a base whose activity amount is unknown, and estimate the activity amount by providing the received attributes to an estimation model for estimating the activity amount. The estimation unit 213 can also receive attribute values ​​(e.g., type and floor area) of a base whose activity amount is unknown, and estimate the activity amount by providing another attribute value (e.g., floor area) to an estimation model for estimating the activity amount corresponding to a received attribute (e.g., type). The estimation unit 213 can calculate the emission amount by multiplying the estimated activity amount by a predetermined emission coefficient.

[0031] 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.
