[0011] <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 (J-credits are assumed in this embodiment, but emission rights other than J-credits can also be applied). Emission rights created by greenhouse gas emission reduction or absorption are matched with the amount of greenhouse gas emissions to be offset. The number of J-credits available varies depending on the greenhouse gas emission activity. In addition, the number of J-credits available for reporting varies depending on the rules such as the Global Warming Act, the Energy Conservation Act, SBT, CDP, and RE100. The information processing system according to this embodiment provides available emission rights to users (hereinafter referred to as users) who wish to offset greenhouse gas emissions.

[0012] 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.

[0013] 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.

[0014] The user terminal 3 is a computer operated by a user. The user terminal 3 may be, for example, a smartphone, a tablet computer, or a personal computer.

[0015] 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.

[0016] The invalidation server 4 is a computer of an organization that issues emission credits and invalidates greenhouse gas emissions based on the emission credits (the organization that operates the J-Credit Scheme). 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).

[0017] <Administration 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.

[0018] 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.

[0019] 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, and an invalidation processing unit 214.

[0020] <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 the name of the emission meter (emission credit name), the attributes of the emission credits, and the maximum value (maximum offsetable amount) and minimum value (minimum offset amount) of the amount of greenhouse gas that can be offset by the emission credits, in association with emission credit specification information (emission credit ID) that specifies the emission credits. The minimum offset amount is used to set the sales unit of the emission credits, and can be set arbitrarily by the holder of the emission credits, and may be set in units of, for example, 1 ton, 50 ton, 100 ton, etc. The attributes may include a methodology related to the emission credits (which specifies the scope of application, the calculation method and monitoring method of the emission reduction and absorption amount for each technology that contributes to emission reduction and absorption). The attributes may include the type of emission credits.

[0021] 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.

[0022] 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).

[0023] <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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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).

[0028] 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.

[0029] 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.

[0030] 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.

[0031] <Operation 1> FIG. 4 is a diagram for explaining the process for revocation information in which the automatic revocation is "false."

[0032] 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 storage unit 231 for emission credit information that corresponds to the acquired attributes and in 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). The management server 2 can transmit the searched emission credit information to the user terminal 3 and present the emission credits to the user (S304). Here, the management server 2 may perform a process of selling the emission credits to the user.

[0033] When the management server 2 receives the invalidation request from the user terminal 3 (S304), 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 (S305).

[0034] 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.

[0035] FIG. 5 is a diagram for explaining the process for invalidation information in which automatic invalidation is "true."

[0036] 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).

[0037] 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).

[0038] 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.

[0039] Next, a conceptual diagram of an information processing system for emissions trading will be described with reference to FIGS.

[0040] Figure 7 is a conceptual diagram of an information processing system in which a user acquires emission rights directly from a holder. The user, who is the buyer, uses the user terminal 3 to inform the holder of the emission rights that he or she intends to purchase the emission rights. If the holder intends to sell the emission rights, the user uses the user terminal 3 to transfer an amount corresponding to the emission rights (the price of the emission rights) to the holder's bank account. Based on the transfer, the holder uses the holder terminal 1 to transfer the emission rights from the holder's account to the user's account. The user acquires the emission rights and performs the invalidation process so that the acquired emissions amount is included in the invalidation notice.

[0041] FIG. 8 is a conceptual diagram of an information processing system in which a user acquires emission rights from a holder via an intermediary. The user, who is a buyer, uses the user terminal 3 to inform the intermediary of his / her intention to purchase emission rights. The holder uses the holder terminal 1 to indicate his / her intention to sell the emission rights to the intermediary and requests that he / she provide the emission rights to a third party. The intermediary recognizes the user's intention to purchase and the holder's intention to sell. The user uses the user terminal 3 to remit an amount corresponding to the emission rights to the intermediary's bank account. The intermediary remits the amount remitted from the user to the holder's bank account. Based on the remittance, the holder transfers the emission rights from the holder's account to the intermediary's account using the holder terminal 1. The intermediary transfers the emission rights from its own account to the user's account. The user performs invalidation processing so that the acquired emission amount is included in the invalidation notice. It is preferable that the intermediary uses an intermediary terminal and an intermediary server as shown in FIG. 9 described later.

[0042] FIG. 9 is a conceptual diagram of an information processing system 1 in which a user acquires emission rights from a holder via a platform having a management server 2. The user, who is a buyer, uses the user terminal 3 to output invalidation information indicating an intention to purchase emission rights to the platform. The holder uses the holder terminal 1 to output emission rights information indicating an intention to sell emission rights to an intermediary server of the intermediary (for example, a system similar to the management server 2) and requests that the emission rights be provided to a third party. The intermediary uses the intermediary terminal and the intermediary server to output the emission rights information of the holder's intention to sell to the platform. The platform matches the emission rights information from the intermediary with the invalidation information from the user. The user uses the user terminal 3 to perform a process of transferring an amount corresponding to the emission rights to the bank account of the platform. The platform performs a process of transferring the amount transferred from the user to the bank account of the intermediary. The intermediary server performs a process of transferring the amount transferred from the user to the bank account of the holder. Based on the transfer being made, the holder uses the holder terminal 1 to output the emission rights information from his / her account to the account of the intermediary, and transfers the emission rights. The intermediary server outputs the emission credit information from its own account to the platform's account and transfers the emission credits. The platform outputs the emission credit information from its own account to the user's account and transfers the emission credits. The user acquires the emission credit information and performs the invalidation process so that the acquired emissions amount is included in the invalidation notice.

[0043] FIG. 10 is a conceptual diagram of an information processing system 2 in which a user acquires emission rights from a holder via a platform having a management server 2. The difference from FIG. 9 is that the invalidation process is executed on the platform. A user who is a buyer uses a user terminal 3 to output invalidation information indicating an intention to purchase emission rights to the platform. The holder uses a holder terminal 1 to output emission rights information indicating an intention to sell emission rights to the intermediary server of the intermediary, and requests that the emission rights be provided to a third party. The intermediary uses a intermediary terminal and an intermediary server to output the emission rights information of the holder that the holder intends to sell to the platform. The platform matches the emission rights information from the intermediary with the invalidation information from the user. The user uses a user terminal 3 to perform a process of transferring an amount corresponding to the emission rights to the bank account of the platform. The platform performs a process of transferring the amount transferred from the user to the bank account of the intermediary. The intermediary server performs a process of transferring the amount transferred from the user to the bank account of the holder. Once the remittance has been made, the holder uses the holder terminal 1 to output the emission rights information from the holder's account to the intermediary's account and transfers the emission rights. The intermediary server outputs the emission rights information from its own account to the platform's account and transfers the emission rights. The platform acquires the emission rights information and performs invalidation processing so that the acquired emissions amount is included in the invalidation notice. The platform also outputs an invalidation notice to the user and transfers the emission rights. By having the platform perform the invalidation on the user's behalf in this way, it is possible to eliminate the need for the user to carry out the invalidation processing.

[0044] FIG. 11 is a conceptual diagram of an information processing system 3 in which a user acquires emission rights from a holder via a platform having a management server 2. The difference from FIG. 10 is that the user collects small-lot requests from small-lot users at a lower level than the user. A small-lot user who wants to use emission rights uses a small-lot user terminal to output invalidation information indicating that the user has an intention to purchase emission rights. When there are multiple small-lot users, invalidation information that is a small-lot request is output from the multiple small-lot users. The user receives the invalidation information. The user uses a user terminal 3 to output invalidation information indicating that the user has an intention to purchase emission rights to the platform. This invalidation information may be multiple invalidation information corresponding to multiple small-lot requests, or invalidation information that is a sum of multiple small-lot requests. In this example, the latter is explained. The holder uses the holder terminal 1 to output emission rights information indicating that the holder has an intention to sell the emission rights to the intermediary server of the intermediary, and requests that the holder wishes to provide the emission rights to a third party. The intermediary uses the intermediary terminal and the intermediary server to output the emission rights information of the holder's intention to sell to the platform. The platform matches the emission credit information from the intermediary with the invalidation information from the user. The user performs a process of transferring the amount corresponding to the emission credits to the bank account of the platform using the user terminal 3. The platform performs a process of transferring the amount transferred from the user to the bank account of the intermediary. The intermediary server performs a process of transferring the amount transferred from the user to the bank account of the holder. Based on the transfer, the holder outputs the emission credit information from the holder's account to the account of the intermediary using the holder terminal 1, and transfers the emission credits. The intermediary server outputs the emission credit information from its own account to the account of the platform, and transfers the emission credits. The platform acquires the emission credit information, and performs invalidation processing so that the acquired emissions are included in the invalidation notice. The platform also outputs the invalidation notice to the user, and transfers the emission credits. The user may output an invalidation notice based on a small-lot request to the small-lot user. By accepting a small-lot request in this way, it is possible to make it easier for small-lot users to use the emission credits. In addition, by having the platform handle the invalidation process on behalf of the user, the user can be relieved of the trouble of having to go through the invalidation process.

[0045] FIG. 12 is a conceptual diagram of an information processing system 4 in which a user acquires emission rights from a holder via a platform having a management server 2. The difference from FIG. 11 is that multiple users output multiple invalidation information to the platform. A small-scale user who wants to use emission rights uses a small-scale user terminal to output invalidation information indicating that the user has an intention to purchase emission rights. When there are multiple small-scale users, invalidation information, which is a small-scale request, is output from the multiple small-scale users. The user receives the invalidation information at the user terminal 3. When there are multiple users, the user receives invalidation information for each user. The user uses the user terminal 3 to output invalidation information indicating that the user has an intention to purchase emission rights to the platform. When there are multiple users, invalidation information is output for each user. The holder uses the holder terminal 1 to output emission rights information indicating that the holder has an intention to sell the emission rights to the intermediary server of the intermediary, and requests that the holder provide the emission rights to a third party. The intermediary uses the intermediary terminal and the intermediary server to output the emission rights information of the holder's intention to sell to the platform. The platform matches the emission rights information from the intermediary with the invalidation information from each user. Each user performs a process of transferring an amount corresponding to the emission credits to the bank account of the platform using the user terminal 3. The platform performs a process of transferring the amount transferred from each user to the bank account of the intermediary. The intermediary server performs a process of transferring the amount transferred from each user to the bank account of the holder. Based on the transfer, the holder outputs the emission credit information from the holder's account to the account of the intermediary using the holder terminal 1, and transfers the emission credits. The intermediary server outputs the emission credit information from its own account to the account of the platform, and transfers the emission credits. The platform acquires the emission credit information, and performs an invalidation process so that the acquired emission amount is included in the invalidation notice. In addition, the platform outputs an invalidation notice to each user, and transfers the emission credits. The user may output an invalidation notice based on a small-lot request to the small-lot user. By accepting a small-lot request in this way, it is possible to make it easier for small-lot users to use the emission credits. In addition, by having the platform perform the invalidation on behalf of the holder, it is possible to save the user the trouble of performing the invalidation process.In addition, the user may execute various processes using the user server.

[0046] FIG. 13 is a conceptual diagram of an information processing system 5 in which a user acquires emission rights from a holder via a platform having a management server 2. The difference from FIG. 12 is that a bank account and a credit account are not set up on the platform. A small-scale user who wants to use emission rights uses a small-scale user terminal to output invalidation information indicating that the user intends to purchase emission rights. If there are multiple small-scale users, invalidation information, which is a small-scale request, is output from the multiple small-scale users. The user receives the invalidation information at the user terminal 3. If there are multiple users, the invalidation information is received for each user. The user uses the user terminal 3 to output invalidation information indicating that the user intends to purchase emission rights to the platform. If there are multiple users, the invalidation information is output for each user. The holder uses the holder terminal 1 to output emission rights information indicating that the holder intends to sell the emission rights to the intermediary server of the intermediary, and requests that the holder wishes to provide the emission rights to a third party. The intermediary uses the intermediary terminal and the intermediary server to output the emission rights information of the holder's intention to sell to the platform. The platform matches the emission rights information from the intermediary with the invalidation information from each user. Each user performs a process of transferring an amount corresponding to the emission credits to the bank account of the intermediary using the user terminal 3. The intermediary server performs a process of transferring the amount transferred from each user to the bank account of the holder. Based on the transfer, the holder outputs the emission credit information from the holder's account to the account of the intermediary using the holder terminal 1, and transfers the emission credits. The intermediary server outputs the emission credit information from its own account to the account of the user, and transfers the emission credits. The intermediary server also acquires the emission credit information, and performs an invalidation process so that the acquired emission amount is included in the invalidation notice. Furthermore, the intermediary server outputs an invalidation notice to each user, and transfers the emission credits. Note that the user may output an invalidation notice based on a small-lot request to the small-lot user. By accepting a small-lot request in this way, it is possible to make it easier for the small-lot user to use the emission credits. Also, by performing the invalidation on the platform's behalf, it is possible to save the user the trouble of performing the invalidation process. Note that the user may perform various processes using the user server.

[0047] Next, we will explain a function that allows users to obtain better purchasing conditions by purchasing emission rights in large lots than by purchasing them in small lots. In this example, we will explain a function that allows users to lower the price (unit price) by jointly purchasing emission rights on the platforms in Figures 12 and 13.

[0048] On the purchase screen of the user terminal 3, a "minimum sales quantity = minimum ticket" according to the price is displayed for each type of emission credit, such as A, B, C, etc. For example, A, which is mediated by company X, a seller of emission credits, has the following minimum sales quantity-price relationship (1) and (2). (1) Over 1 million tons: 8,000 yen / ton-CO2 (2) Over 10 million tons: 7,000 yen / ton-CO2

[0049] Condition (1) is a condition that, when purchasing emission rights, if the total amount of emission rights in the joint purchase including other users is more than 1 million tons but less than 10 million tons, then emission rights can be purchased at a price (unit price) of 8,000 yen per ton-CO2. Condition (2) is a condition that, when purchasing emission rights, if the total amount of emission rights in the joint purchase including other users is more than 10 million tons, then emission rights can be purchased at a price (unit price) of 7,000 yen per ton-CO2. In this way, it is possible to present to the user terminal 3 conditions that set the minimum sales quantity and price so that the unit price of emission rights varies depending on the total amount of emission rights in the joint purchase.

[0050] When Company X puts up for sale on the platform, if the platform management server 2 is set up to solicit participants for a joint purchase, users who are willing to purchase at a unit price of 10 million tons or more as specified in condition (2) can express their willingness to purchase using the user terminal 3. For example, if multiple users express their willingness to purchase on the user terminal 3 and 7 million tons of the 10 million tons have been collected, the output unit of the management server 2 outputs information about the display image to the user terminal 3 so that an image such as "When we gather buyers for the remaining 3 million tons, the transaction will be concluded at a unit price of 7,000 yen" can be displayed on the user terminal 3. In addition, the output unit of the management server 2 outputs information about the display image to the user terminal 3 so that a gauge image showing 7 million tons / 10 million tons and an image showing the current unit price of 8,000 yen can also be displayed together with this image. When multiple users indicate their intention to purchase on the user terminal 3 and 10 million tons of the 10 million tons are collected, information about the display image is output from the output unit of the management server 2 to the user terminal 3 so that an image such as "Conditions achieved" can be displayed on the user terminal 3. In addition, information about the display image is output from the output unit of the management server 2 to the user terminal 3 so that a gauge image showing 10 million tons / 10 million tons and an image showing 7000 yen, which is the unit price after the conditions are achieved, can be displayed together with this image. With this configuration, users who wish to purchase emission rights can obtain advantageous trading conditions, so the number of users who wish to purchase emission rights increases. As the number of such users increases, the number of holders who wish to sell emission rights also increases, so the amount of emission rights trading increases and emission rights trading becomes lively, which solves the problem of a small number of participants in emission rights trading making it difficult to complete emission rights trading. In addition, users can check the process leading up to the achievement of the conditions, so users can purchase emission rights at the target unit price while checking this process. Company X, which is the seller of the emission rights, is either the holder of the emission rights or an intermediary. Also, although the example in which the user uses the user terminal 3 shown in Figures 12 and 13 is shown, an example in which a person making a small-lot request uses a small-lot user terminal may also be used.In the above paragraph, an example has been described in which a person wishing to purchase emission rights can obtain favorable purchasing conditions. However, a person wishing to sell emission rights may be able to obtain favorable selling conditions through joint sales. <Operation 2> FIG. 14 is a diagram illustrating the operation of the management server 2. As shown in FIG.

[0051] The management server 2 sets up a call for participants (S1401). In detail, the offsettable amount, which is the amount of greenhouse gas that can be offset by offsettable emission credits, is stored in the emission credit storage unit. The management server 2 also makes it possible to accept input of the amount of emissions that a plurality of users wish to offset. Furthermore, the management server 2 outputs information such as images to display the following images (1) and (2) on the user terminal 3, and calls for participants in the joint purchase. (1) Over 1 million tons: 8,000 yen / ton-CO2 (2) Over 10 million tons: 7,000 yen / ton-CO2

[0052] Next, the management server 2 sets a first price (S1402). For example, 8000 yen of condition (1) is set as the first price. Next, the management server 2 receives purchase intentions from users (S1403). Next, the management server 2 sums up the purchase intentions from users (S1404). Next, the management server 2 judges whether the sum of the purchase intentions is greater than the minimum sales quantity (S1405). In detail, it judges whether the sum of the input purchase intentions (emission amount) (e.g., 10 million tons) is greater than the value corresponding to the offsettable amount, which is the minimum sales quantity (e.g., 10 million tons). If the answer is Yes in S1405, the management server 2 sets a second price (S1404). For example, 7000 yen of condition (2) is set as the second price. In addition, the management server 2 acquires emission credit specification information (emission credit ID) that specifies the emission credit. If the answer is No in S1405, the management server 2 ends this process. In this case, the price remains at the first price, 8,000 yen. The processing of this operation 2 is executed within a predetermined period. Therefore, for example, if condition (2) cannot be achieved within the predetermined period, condition (1) applies. If condition (1) cannot be achieved within the predetermined period, emission rights may be purchased at a unit price different from that of condition (1), or emission rights may not be purchased. Also, while an example has been given in which the user uses the user terminal 3, an example in which a person making a small-lot request uses a small-lot user terminal may also be used. Also, <operation 2> may be combined with <operation 1> or <operation 3> described below.

[0053] Next, a function of analyzing the past and future surface conditions at each base in a time series using satellite data will be described. The base in this example may be, for example, a place where greenhouse gas emitting activities are performed, such as a business office or a factory, or may be a predetermined area where an entity that performs activities that emit greenhouse gases exists, including one or more business offices or factories. The predetermined area is preferably an area of ​​a predetermined area. The satellite data is image data taken from a GPS satellite. The satellite data is image data of the base of the entity that emits greenhouse gases, and is image data showing an area of ​​a predetermined area. The satellite data is acquired by the acquisition unit 215. The image data to be analyzed is the first satellite data acquired at a first point in time (for example, one year ago) and the second satellite data acquired at a second point in time (for example, the present), and these are compared and analyzed. The first satellite data and the second satellite data are image data showing an area of ​​the same area (the same base). The analysis is performed by the analysis unit 216. The analysis is performed by comparing the green space area and the forest area in the image data. By analyzing the satellite data in this way, it is possible to analyze changes in land use over time, such as the reduction of green spaces and forests. Furthermore, by analyzing the satellite data, it is possible to estimate and register the amount of activity at the base. Furthermore, by analyzing the satellite data, it is possible to estimate and register the amount of greenhouse gas emissions that can be offset. By such an analysis, it is possible to easily register the amount of activity at the base and the amount of greenhouse gas emissions that can be offset. Registration is performed by the registration unit 217. Furthermore, this analysis makes it possible to analyze biodiversity risks, etc. This is particularly effective in identifying materiality. Furthermore, it can lead to greenwashing. Note that there are cases where offsetting is not possible depending on the analysis results, in which case it is possible to estimate and register the amount of greenhouse gas emissions that cannot be offset.

[0054] <Operation 3> FIG. 6 is a diagram for explaining the operation of the management server 2. As shown in FIG.

[0055] The management server 2 acquires satellite data of the base of the greenhouse gas emitter (S601). Next, the management server 2 analyzes the satellite data in a time series (S602). Next, the management server 2 estimates the offsettable greenhouse gas emissions at the base based on the analysis result and registers it in the registration unit 217 (S603). Next, the management server 2 may be configured as follows. The management server 2 registers the activity amount at the base in the registration unit 217 based on the analysis result. The management server 2 identifies the position of the base from the satellite data, and stores the position information of the identified base in the base information storage unit. The management server 2 accepts input of the position information of the base and the activity amount by the emitter in the activity amount input unit. The management server 2 refers to the base information storage unit and identifies the base based on the position information by the base identification unit. The management server 2 registers the activity amount at the base in the activity amount storage unit based on the analysis result. Also, the management server 2 registers the input activity amount in the activity amount storage unit in association with the identified base. In addition, <operation 3> may be combined with <operation 1> or <operation 2>.

[0056] 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.

[0057] 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.

[0058] 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. [Explanation of symbols]
