DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] <System Overview> An information processing system according to an embodiment of the present invention will be described below. The information processing system according to this embodiment is intended to support trading of greenhouse gas emission rights (for example, in Japan, J-Credit, which is a domestic system, is known. Also, there may be multiple emission rights depending on the country or region. For example, the UN-led Kyoto Mechanism Credit (JI, CDM), the Bilateral Crediting Mechanism (JCM), each domestic system, and private-sector led voluntary credit. Hereinafter, these are collectively referred to as emission rights). Note that emission rights trading is a comprehensive concept including emissions trading and emissions allowance trading, or a concept identical or similar to these, and the same applies below. The information processing system according to this embodiment provides emission rights that can be used for offsetting at the user's location to a user (hereinafter, referred to as a user) who wishes to offset 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 communicatively connected to each of an owner terminal 1, a user terminal 3, and an invalidation server 4 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.

[0012] The holder terminal 1 is a computer operated by a user who has created an emission credit by reducing or absorbing greenhouse gas emissions (hereinafter, referred to as an emission credit holder). The holder terminal 1 may be, for example, a smartphone, a tablet computer, or a personal computer.

[0013] The user terminal 3 is a computer operated by a user of the emission credits. The user terminal 3 may be, for example, a smartphone, a tablet computer, or a personal computer.

[0014] The management server 2 is a computer that manages information related to emission rights and proposes emission rights to users. 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.

[0015] The invalidation server 4 is a computer of an organization that issues emission credits and invalidates greenhouse gas emissions based on the emission credits (for example, an organization that operates the J-Credit Scheme, etc.). In this embodiment, it is assumed that the invalidation process is performed by sending a request to invalidate the emission credits to the invalidation server 4 (including, for example, sending a request for invalidation by email).

[0016] <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 is, for example, a hard disk drive, a solid state drive, or a flash memory that stores various data and programs. The communication interface 204 is an interface for connecting to a communication network, for example, an adapter for connecting to Ethernet (registered trademark), a modem for connecting to a public telephone line 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, for example, a keyboard, a mouse, a touch panel, a button, a microphone, etc. that input data. The output device 206 is, for example, a display, a printer, a speaker, etc. that output 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.

[0017] The hardware configurations of the owner terminal 1, the user terminal 3, and the invalidation server 4 may be the same as that of the management server 2.

[0018] 3 is a diagram showing an example of the software configuration of the management server 2. The management server 2 includes an emission credit storage unit 231, an offset attribute storage unit 232, an invalidation information storage unit 233, an input unit 211, an emission credit acquisition unit 212, a request reception unit 213, an invalidation processing unit 214, a location information acquisition unit 215, and a region identification unit 216.

[0019] <Storage section> The emission credit storage unit 231 stores information on emission credits that can offset greenhouse gas emissions (hereinafter, referred to as emission credit information). The emission credit information may include, in association with emission credit specification information (emission credit ID) that specifies the emission credit, the name of the emission meter (emission credit name), the attributes of the emission credit, the region (country / region) in which the emission credit can offset greenhouse gas emissions, and the maximum amount (maximum offsetable amount) and minimum amount (minimum offset amount) of the amount of greenhouse gas that can be offset by the emission credit. The minimum offset amount is used to set the sales unit of the emission credit and can be set arbitrarily by the holder of the emission credit, and may be set in units of, for example, 1 t, 50 t, 100 t, etc. The attributes may include a methodology related to the emission credit (which specifies the scope of application, the calculation method and monitoring method of the emission reduction / absorption amount for each technology that contributes to emission reduction / absorption). The attributes may include the type of emission credit. The country / region may be identified by an address (country, city, town, or village, etc.) or by latitude and longitude (which may be a single point, multiple latitudes and longitudes, or a geofence).

[0020] The offset attribute storage unit 232 stores attributes of emission credits that can offset emissions related to an activity, in association with activity specific information that identifies the activity. In this embodiment, the offset attribute storage unit 232 stores rule specific information that identifies rules related to reporting emissions, activity specific information, and attributes in association with each other. The rule specific information can be, for example, "Act on Global Warming Countermeasures," "Energy Conservation Act," "Carbon Offset," "CDP Questionnaire," "SBT," "RE100," etc. The activity specific information can be, for example, "fuel combustion," "electricity use," etc.

[0021] The invalidation information storage unit 233 stores information about the emission amount that the user wishes to offset (hereinafter referred to as invalidation information). The invalidation information can include an invalidation ID that identifies the invalidation information, rule specification information, activity specification information, and the emission amount that the user wishes to offset. The invalidation information can also include information indicating whether or not the management server 2 will automatically perform invalidation processing (automatic invalidation).

[0022] <Functional section> The input unit 211 can accept input of activity specification information that specifies the activity for which the user wishes to offset, and the emission amount related to the activity. In this embodiment, the input unit 211 accepts input of invalidation information. The input unit 211 can transmit screen information that displays an input form for the invalidation information to the user terminal 3, and can accept the invalidation information by receiving data of each item of the invalidation information from the user terminal 3. The input unit 211 can register the accepted invalidation information in the invalidation information storage unit 233.

[0023] The emission credit acquisition unit 212 identifies emission credits that can be presented for the invalidation information. The emission credit acquisition unit 212 can identify attributes corresponding to activity specifying information included in the invalidation information by referring to the offset attribute storage unit 232 and the emission credit storage unit 233, and acquire emission credit specifying information corresponding to the identified attributes and the maximum offsettable amount equal to or greater than the emission amount included in the invalidation information. Furthermore, when rule specifying information is set in the invalidation information, the emission credit acquisition unit 212 can identify attributes corresponding to the rule specifying information and activity specifying information included in the invalidation information from the offset attribute storage unit 232.

[0024] The emission credit acquisition unit 212 can present the identified emission credits to the user. The emission credit acquisition unit 212 can transmit the emission credit information to the user terminal 3, for example.

[0025] The emission rights acquisition unit 212 may search for invalidation information capable of presenting the emission rights for the emission rights information. For example, the emission rights acquisition unit 212 can select a combination (which may be one) of invalidation information such that the emission amount (when there is one invalidation information) or the total emission amount (when there are multiple invalidation information) included in the invalidation information is equal to or less than the maximum offsettable amount of the emission rights information for the emission rights information. The emission rights acquisition unit 212 can also select a combination (which may be one) of invalidation information such that the emission amount (when there is one invalidation information) or the total emission amount (when there are multiple invalidation information) included in the invalidation information is equal to or more than the minimum offsettable amount. For example, for one emission rights information, the emission rights acquisition unit 212 can select a combination such that the total emission amount included in the invalidation information is equal to or more than a predetermined value or is the maximum, from among invalidation information (or combinations) in which the emission amount (or the total amount) included in the invalidation information is equal to or less than the maximum offsettable amount of the emission rights information and equal to or more than the minimum offsettable amount.

[0026] The request receiving unit 213 can receive an invalidation request from the user terminal 3. The request can include information for identifying the invalidation information (for example, an invalidation ID) and information for identifying the emission credits (for example, an emission credit ID).

[0027] The invalidation processing unit 214 performs processing related to invalidating emission amounts using emission credits (hereinafter referred to as invalidation processing). As the invalidation processing, the invalidation processing unit 214 can, for example, transmit an invalidation request including information identifying the emission credits and invalidation information to the invalidation server 4. In this case, the operator of the management server 2 will perform the invalidation on behalf of the user. Note that the invalidation may also be performed by the user himself.

[0028] For invalidation information in which automatic invalidation is "false", the invalidation processing unit 214 can perform the invalidation process in response to a request for invalidation from the user terminal 3. For invalidation information in which automatic invalidation is "true", the invalidation processing unit 214 can perform the invalidation process without receiving a request from the user terminal 3. In this case, prior to the invalidation process, the invalidation processing unit 214 can perform a sale process of the emission rights from the holder to the user. Note that the sales process will not be described here as it uses the process used in a general trading system.

[0029] In addition, when performing invalidation processing on multiple pieces of invalidation information using one emission right, the invalidation processing unit 214 can perform processing related to the invalidation (e.g., sending an invalidation request to the invalidation server 4) so ​​that the activity specific information and emission amounts contained in each piece of invalidation information are included in the invalidation notice.

[0030] The location information acquisition unit 215 acquires location information of the user. The user terminal 3 can acquire information indicating the location of the user terminal 3 on a map (for example, the location may be represented by latitude and longitude, may be represented by city, ward, town, village, or may be represented by information identifying a beacon in a known location) by using existing technology such as GPS or beacon, and transmit it to the management server 2, and the location information acquisition unit 215 can receive it. The location information acquisition unit 215 may transmit a request to the user terminal 3 to acquire location information from the user terminal 3, or may receive location information periodically transmitted from the user terminal 3. The location information acquisition unit 215 may identify the location of the user by, for example, analyzing an image of a security camera that has captured the user or the user terminal 3, and create location information indicating the identified location.

[0031] The area identification unit 216 identifies the area where the user is currently located. For example, the area identification unit 216 can acquire location information expressed by latitude and longitude, and acquire an area (address, postal code, etc.) corresponding to the latitude and longitude by using a reverse geocoding API provided by the map server. The area may include a country. Note that the management server 2 may include an area information storage unit that stores in advance a figure (geofence) surrounding an area such as a country, a region, or a city, ward, town, or village, and the area identification unit 216 may search the area information storage unit for a geofence including the location information to identify the area.

[0032] The emission rights acquisition unit 212 can present emission rights to the user by narrowing down the emission rights information to those corresponding to the region specified by the region specification unit 216. Whether or not the emission rights information corresponds to the region specified by the region specification unit 216 may be determined based on whether the region matches or is similar to the "country / region" of the emission rights information, or based on whether or not the location information (latitude and longitude) is included in a geofence set for the country / region. In addition, the area (geofence) corresponding to the region of the emission rights information may be obtained from a map server or the like by, for example, geocoding, and the determination may be made based on whether or not the location information is included in the obtained area.

[0033] <Operation> FIG. 4 is a diagram for explaining the process for revocation information in which the automatic revocation is "false."

[0034] The management server 2 accepts input of invalidation information from the user terminal 3 and registers it in the invalidation information storage unit 233 (S301). The management server 2 acquires attributes corresponding to the rule specifying information and activity specifying information included in the invalidation information from the offset attribute storage unit 232 (S302), and searches the emission credit information from the emission credit storage unit 231 for emission credit information that corresponds to the acquired attributes and for which the emission amount of the invalidation information is equal to or greater than the minimum offsettable amount and equal to or less than the maximum offsettable amount (S303). Note that the management server 2 may specify an area corresponding to the location information acquired from the user terminal 3, and may search for emission credit information by narrowing down the search to only emission credit information corresponding to the specified area. The management server 2 may transmit the searched emission credit information to the user terminal 3 and present the emission credits to the user (S304). The management server 2 may perform a process of selling the emission credits to the user.

[0035] When the management server 2 receives the invalidation request from the user terminal 3 (S305), it performs invalidation processing using the emission credits related to the emission credit information, based on the emission credit information and invalidation information specified in the request (S306).

[0036] In this way, the management server 2 can present users with emission credits that can offset emissions. In addition, the management server 2 can invalidate emissions on behalf of users in response to their requests.

[0037] FIG. 5 is a diagram for explaining the process for invalidation information in which automatic invalidation is "true."

[0038] The management server 2 accepts input of revocation information from the user terminal 3 and registers the information in the revocation information storage unit 233 (S321).

[0039] The management server 2 acquires rules and activities corresponding to the attributes of the emission rights information from the offset attribute storage unit 232 (S322). The management server 2 reads out invalidation information corresponding to the acquired rules and activities from the invalidation information storage unit 233, and selects a combination of invalidation information from the read out invalidation information such that the total emission amount is equal to or greater than the minimum offsettable amount and equal to or less than the maximum offsettable amount (S323). Here, the management server 2 can select a combination such that the total emission amount is equal to or greater than a predetermined value. The management server 2 may also select a combination such that the total emission amount is maximized. The management server 2 can perform invalidation processing such that the activity specification information and emission amount included in each of the invalidation information included in the selected combination are included in the invalidation notice (S324).

[0040] In this way, the management server 2 can automatically execute invalidation processing for emission amounts that are received from users and for which offsetting is desired. Therefore, for example, invalidation information related to emission amounts less than the minimum offsettable amount can be invalidated together. Also, when offsetting emission amounts less than the maximum offsettable amount, invalidation can be performed together with other invalidation information.

[0041] 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 of the present invention, and equivalents thereof are also included in the present invention.

[0042] For example, in the present embodiment, one or more pieces of invalidation information are matched to one piece of emission rights information, but one or more pieces of invalidation information may be matched to multiple pieces of emission rights information. In this case, for example, when there is a remainder (fraction) in the emission amount of the invalidation information in units of the minimum offsettable amount, another emission rights information may be matched by the fraction.

[0043] For example, in this embodiment, the management server 2 automatically performs the invalidation process (acts as a proxy for invalidation), but the management server 2 may simply present to the user the emission credits that can be used for invalidation.
