Mode for Carrying Out the Invention

[0010] <Overview of the System> FIG. 1 is a diagram showing an overall configuration example of an information processing system according to an embodiment of the present invention. The information processing system of the present embodiment includes a management server 2. The management server 2 is communicably connected to the user device 1 via a communication network. The communication network is, for example, the Internet, and is constructed by a public telephone line network, a mobile phone line network, a wireless communication path, Ethernet (registered trademark), or the like.

[0011] The user device 1 is a computer operated by a user of a business entity such as a company that is an emission entity. The user device 1 can be, for example, a smartphone, a tablet computer, a personal computer, or the like.

[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] <Management Server> FIG. 2 is a diagram showing an example of the hardware 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 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, such as 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, such as an adapter for connecting to Ethernet (registered trademark), a modem for connecting to a public telephone network, a wireless communication device for performing wireless communication, a USB (Universal Serial Bus) connector or an RS232C connector for serial communication. The input device 205 inputs data, such as a keyboard, a mouse, a touch panel, a button, or a microphone. The output device 206 outputs data, such as a display, a printer, or a speaker. Note that each functional unit of the management server 2 described later 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 a part of the storage area provided by the memory 202 and the storage device 203.

[0014] FIG. 3 is a diagram showing an example of the 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 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 emissions of a business entity from the attributes of the business entity. The estimation model is created by analyzing the relationship between the attribute values related to the attributes of the bases of the activities that emit greenhouse gases and the amount of greenhouse gas emissions. The estimation model is, for example, a statistical model that analyzes the correlation between the attribute values and the emissions. In the present embodiment, the attribute value is assumed to be the floor area of the base. Therefore, the estimation model may be represented, for example, by an equation that multiplies the floor area by the emissions per unit area of the floor area of the base. The estimation model may be created by machine learning using the attribute values as input data and the emissions as teacher data. In addition, the attribute values may include the type of the base (type of activity at the base). In the present embodiment, the model storage unit 231 can store the estimation model for each type of base in association with the business entity. The type of the base can be the type of business (type of activity) conducted at the base. The type of the base can be, for example, an office, a factory, a manned store, an unmanned store where an automated teller machine is installed, etc. The estimation model may be a model that estimates the emissions by using both the floor area and the type of activity as feature amounts. In addition, the attribute values may include the industry of the business entity. The model storage unit 231 may, for example, store the estimation model in association with the industry of the business entity and the type of the base. In addition, the estimation model may be a model that estimates the emissions by giving the industry, the type of the base, and the floor area. Note that, as the attribute values, in addition to or instead of the floor area, for example, the volume of the building of the base, the height of the building of the base, the location where the base exists (region, prefecture, municipality, latitude and longitude, etc.), the department using the base, etc. may be adopted.

[0016] The business entity information storage unit 232 stores information related to the business entity (hereinafter referred to as business entity information). The business entity information may include the industry of the business entity in association with the information for identifying the business entity (business entity ID). The business entity information may also include the sales scale, asset scale, number of bases, etc. of the business entity.

[0017] The emission amount storage unit 233 stores the greenhouse gas emission amount 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 the time information. Regarding Scopes 1 and 2, the category may not be registered.

[0018] The emission amount calculation unit 211 calculates the greenhouse gas emission amount by the business entity. The emission amount calculation unit 211 can calculate the emission amount, for example, by obtaining the activity amount by the business entity and multiplying it by a predetermined emission coefficient. The emission amount calculation unit 211 can calculate the emission amount for each site. Note that a known method can be used for the calculation of the emission amount by the emission amount calculation unit 211, and detailed description is omitted here. The emission amount calculated by the emission amount calculation unit 211 is registered in the emission amount storage unit 233. For sites where the activity amount cannot be obtained, the emission amount is estimated by the estimation unit 213 described later.

[0019] The attribute value acquisition unit 212 acquires the attribute value related to the attribute of the site. The attribute value acquisition unit 212 can acquire the attribute value for each site. The attribute value acquisition unit 212 may acquire the attribute value only for sites where the emission amount is unknown. The attribute value acquisition unit 212 can acquire the type of the site and the attribute value other than the said type. In this embodiment, the attribute value acquisition unit 212 acquires the type of the site and the floor area of the site. The attribute value acquisition unit 212 can receive, for example, the attribute value input by the user device 1. An attribute value storage unit that stores the attribute value for each site may be provided, and the attribute value acquisition unit 212 may read the attribute value from the attribute value storage unit.

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

[0021] If the 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 the emissions using the estimation model corresponding to another business entity of the same industry type 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 type of the business entity to which the user belongs and identify other business entities of the same industry type as the identified one. Also, in this case, the estimation unit 213 may acquire the industry type, sales scale, asset scale, or number of sites of the business entity to which the user belongs or a combination of at least two of these, and identify other business entities corresponding to the acquired ones. Note that a specific unit different from the estimation unit 213 may be provided to identify the business entity or the industry type of the business entity.

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

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

[0024] The management server 2 calculates the emissions for each site (S301). For a site for which the emissions cannot be calculated, it acquires the type and floor area of the site (S302), gives the floor area to the estimation model corresponding to the received site type, and estimates the emissions (S303), and registers the calculated emissions and the estimated emissions (S304).

[0025] As described above, according to the information processing system of the present embodiment, even for a site for which it is difficult to calculate the emissions, the emissions can be estimated from its attributes.

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

[0027] Also, in the above-described embodiment, the emissions are estimated, but the activity amount may be estimated.

[0028] In this case, the model storage unit 231 can store an estimation model for estimating the activity amount from the attributes of the site, which is created by analyzing the relationship between the attributes of the site (for example, type and floor area) and the actual value of the activity amount at the site, instead of or in addition to the estimation model for estimating the emissions. A value representing the type or a dummy value may be given as a feature amount to the estimation model.

[0029] Also, the management server 2 is provided with an activity amount storage unit (not shown) for storing the activity amount. The activity amount storage unit can store the activity amount in association with the business entity ID indicating the business entity, the site ID identifying the site, the time information, and the scope and category.

[0030] The estimation unit 213 can receive the attribute values (e.g., type and floor area) of a site with unknown activity amount, provide the received attributes to an estimation model for activity amount estimation, and estimate the activity amount. Further, the estimation unit 213 can receive the attribute values (e.g., type and floor area) of a site with unknown activity amount, and provide other attribute values (e.g., floor area) to an estimation model for activity amount estimation corresponding to a certain received attribute (e.g., type) to estimate the activity amount. The estimation unit 213 can calculate the emission amount by multiplying the estimated activity amount by a predetermined emission factor.

[0031] As described above, the present embodiment has been explained. However, the above embodiment is for facilitating the understanding of the present invention and is not for limiting the interpretation of the present invention. The present invention can be changed and improved without departing from its gist, and equivalents thereof are also included in the present invention.
