In particular, the present invention relates to a technology that visualizes and shares the results of efforts toward the realization of a decarbonized society for each cell that divides a region into specified units on a map, thereby increasing motivation for the efforts. [Background technology]

[0002] Today, the world is beginning to move towards a carbon-neutral society. Approximately 40 billion tons of CO2 have been emitted in the past year, and 40 million tons of CO2 have been captured and are beginning to be utilized. In order to achieve a carbon-neutral society, it is necessary to reduce CO2 emissions while simultaneously increasing the amount of CO2 captured to several hundred times the current level.

[0003] It is said that the biggest cause of global warming is CO2 emissions, and it is important for each of us to change our behavior. However, while there are various initiatives to reduce CO2 emissions, such as refraining from driving and bringing our own bags when shopping, there is also the issue that it is difficult to feel close to invisible CO2, and people are not able to continue these actions.

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0015] The trading system, trading method, and management server according to the embodiment of the present invention provide a marketplace for trading non-fungible tokens (hereinafter abbreviated as NFTs) of digital twins related to facilities for a decarbonized society, such as CO2 capture facilities and mega solar facilities. Naturally, the facilities referred to here conceptually include factories, smart cities, and the like.

[0016] When general users become the digital owner of equipment by purchasing NFTs, they can check the amount of CO2 captured by each piece of equipment on a daily basis, acquire value according to the amount of CO2 captured, and utilize the accumulated value. In this way, the amount of CO2 captured by the equipment they are the digital owner of can be visualized and confirmed on a daily basis, making "CO2 reduction" a more personal experience for general users.

[0017] Therefore, it will serve as a bridge to decarbonization hard tech, which is relatively unfamiliar to general users, and by using a new method to close the gap between CO2 capture equipment and consumers, it will influence behavioral change around the world and contribute to accelerating global efforts toward the ambitious goal of realizing a decarbonized society by 2050.

[0018] To achieve the above-mentioned effects, the trading system, trading method, and management server according to the embodiment of the present invention operate and manage an NFT marketplace. This marketplace allows not only the buying and selling of NFTs, but also various other transactions such as resale and auction of NFTs. In the course of transactions in this marketplace, the value of the NFT will increase, and the accumulated value will indicate the status and asset value of the NFT.

[0019] In addition to the above, according to the trading system etc. of the embodiment of the present invention, a virtual world is constructed in which the earth is divided into predetermined units such as latitude and longitude, each divided square is defined as a cell, and the results of the efforts to realize a decarbonized society (e.g., CO2 reduction amount, etc.) assigned to each cell are visualized and shared. This visualization and sharing of results can increase the motivation of companies rooted in the region and users who have an attachment to the region, and can further accelerate the efforts.

[0020] FIG. 1 shows the configuration of a trading system according to an embodiment of the present invention.

[0021] As shown in the figure, a trading system according to an embodiment of the present invention realizes trading of NFTs related to digital twins of facilities toward a carbon-free society. The trading system includes a management server 1, a user terminal 2, a corporate server 3, a relay server 4, and a blockchain 5. The management server 1 is connected to the user terminal 2, the corporate server 3, and the relay server 4 via a network 6 such as the Internet. As the user terminal 2, various devices such as a smartphone, a tablet terminal, a notebook personal computer, or a desktop personal computer can be used.

[0022] Here, "user" refers to general consumers who wish to make transactions such as purchasing NFTs. In FIG. 1, only one user terminal 2 is illustrated, but in reality, there are multiple user terminals 2. On the other hand, "companies" are owners of equipment aimed at a carbon-free society, and are entities that wish to trade NFTs related to their equipment through this service. In FIG. 1, only one corporate server 3 is illustrated, but in reality, there are multiple corporate servers 3. Of course, these corporate servers 3 include not only owners of the equipment, but also companies and local governments that conduct corporate PR and campaigns for cells, which will be described later.

[0023] Blockchain 5 is a technology that combines encryption technology with multiple computers that make up a distributed network, and then synchronizes and records NFTs. In this embodiment, for example, a distributed application platform equipped with a smart contract function can be used as the blockchain 5. However, it is not limited to this, and can be linked to a wide variety of platforms.

[0024] In this configuration, when a company that owns equipment for a decarbonized society desires to trade using this service, the company applies for the service. When applying, the company server 3 transmits data related to the equipment to the management server 1. When the management server 1 accepts the application, it generates a digital twin based on the data related to the equipment. Here, the "digital twin" is not, for example, a simple visual copy of equipment for a decarbonized society operated by a company, but data that allows the operation information of the equipment to be synchronized between the real world and the virtual world. In this embodiment, a digital twin is generated based on image data and specification data of equipment for a decarbonized society transmitted from a company, which realizes synchronization with the operation data of the equipment in the real world.

[0025] Next, the management server 1 issues an NFT for the digital twin on the blockchain 5 and performs distributed ledger management. After this, the NFT will be available to the general public on a marketplace operated by the management server 1, and various transactions, such as purchases, will be carried out in response to requests.

[0026] When a request to purchase an NFT is made by the user terminal 2, the management server 1 updates the registration information of the NFT, executes a prescribed payment process, and then sends a notification of the completion of the transaction to the user terminal 2. Here, updating the registration information is an internal process that links the user information of the user as the purchaser to the NFT registration information managed within the management server 1, and the owner of the NFT managed in the blockchain 5 remains the operator. When the management server 1 receives a request from the purchaser to transfer ownership of the NFT, it executes a transaction on the smart contract to transfer ownership of the NFT.

[0027] At companies participating in this service, the company servers 3 periodically transmit operation information of facilities and other equipment aimed at a decarbonized society that have already been converted into NFTs to the relay server 4. The relay server 4 compiles and stores the operation information sent individually from multiple company servers 3. The management server 1 reads out the operation information stored by the relay server 4 at a predetermined timing, calculates the value to be returned to users who are NFT purchasers based on the operation information, and updates the value information associated with the user information.

[0028] Users can check the accumulated value at any time on their My Page on the marketplace, and can utilize the value in electronic payments, etc. Here, the value refers to at least one of points, miles, virtual currency, financial asset tokens, and in-service currency. For example, points are something that are usually used with 1 point being worth 1 yen, and miles have asset value such as 100 miles being exchanged for a cup of coffee, or 100 miles being exchanged for 200 points from a certain business.

[0029] In addition to the above, in the trading system according to this embodiment, a mesh-shaped virtual world is constructed by dividing the earth into specific latitude and longitude units, and each square in the division is defined as a cell. Of the amount of CO2 reductions made by equipment linked to the NFT in the real world, only the amount of CO2 reductions made on the day the digital owner of the NFT sent a support notification (hereinafter referred to as an "yell") is counted up as a consideration for CO2 reductions in the virtual world. Therefore, the digital owner of the NFT can realize that he or she is ultimately contributing to the achievement of carbon neutrality worldwide by allocating the amount of CO2 reductions made in the virtual world to a desired cell and achieving carbon neutrality for each cell. In addition, when carbon neutrality is achieved in each cell, data such as the geographical information and the date and time of achievement of the cell is used as input to generate AI art (reward image) that indicates the cell (region), and the image is given to the digital owner. The reward image is based on AI art, but may also be collaborative art with artists or characters associated with the cell, corporate tie-up art, etc.

[0030] The trading system manages the status of CO2 reduction, index images (including reward images), the number of cheers from NFT digital owners, donation amounts, the operation volume of actual equipment, CO2 reduction power, etc., so users can check the results of CO2 reduction efforts on a cell-by-cell basis. In addition, it is also possible for local businesses and local governments to conduct PR and campaigns for each cell.

[0031] Furthermore, the trading system issues and presents a digital certificate (index image) indicating the degree of environmental contribution to the digital owner who sent the cheer. Therefore, by checking the index image of each cell, users can check the degree of CO2 reduction achievement of the cell they are supporting, that is, the region, as appropriate, in a visualized index image, which increases users' motivation to support the region, promoting support activities and ultimately accelerating efforts related to CO2 reduction in each region.

[0032] 2(a), 2(b) and 2(c) show the configuration of the management server of the trading system and will be described.

[0033] As shown in the figure, the management server has a control unit 11, a communication unit 12, and a storage unit 13. The control unit 11, the communication unit 12, and the storage unit 13 are communicatively connected via a bus line. In addition, the management server may have an input unit such as a keyboard or a mouse, and a display unit such as a liquid crystal display for performing various displays. The communication unit 12 is realized by, for example, a network interface card (NIC) or the like, and is a communication interface that is connected to a network 6 such as the Internet by wire or wirelessly and communicates with the user terminal 2, the enterprise server 3, the relay server 4, etc.

[0034] The storage unit 13 is realized by, for example, a semiconductor memory element such as a random access memory (RAM) or a flash memory, a hard disk drive (HDD), a solid state drive (SSD), or the like, and stores a program executed by the control unit 11. Here, the storage unit 13 has, for example, a user information storage unit 14, a company information storage unit 15, a digital twin storage unit 16, an NFT storage unit 17, a management information storage unit 18, and a transaction information storage unit 19.

[0035] That is, in more detail, the user information storage unit 14 is a database that stores a user's name, email address, payment information, transaction history information, value history information, cheer information (including remaining cheer points, annually earned cheer points, and lifetime earned cheer points), etc., linked to a user ID. The company information storage unit 15 is a database that stores the company's name, facility location (latitude and longitude of location, etc.), manager's email address, payment information, transaction history information (including product ID), PR information, campaign information, etc. Furthermore, the digital twin storage unit 16 is a database that stores digital twin information, etc. related to the product, linked to a product ID.

[0036] The NFT memory unit 17 is a database that stores the product ID, provider (company ID), purchaser (user ID), owner, transaction terms, etc., which are linked to the NFT ID to identify the digital twin information that is the subject of the NFT.

[0037] The management information storage unit 18 is a database that stores CO2 reduction status, index images, cheer information (e.g., cheer count, etc.), donation information (e.g., donation amount, etc.), actual equipment operation volume, CO2 reduction power, corporate PR information (including corporate ID), campaign information, etc. The transaction information storage unit 19 is a database that stores NFT IDs that identify transaction targets by linking them to transaction IDs, transaction history information, etc. Note that these are merely examples, and the present invention is not limited to these, of course.

[0038] The control unit 11 is realized by a CPU (Central Processing Unit), MPU (Micro Processing Unit), etc., and functions as, for example, a transmission / reception control unit 11a, a digital twin management unit 11b, an NFT management unit 11c, a marketplace management unit 11d, a transaction processing unit 11e, an operation management unit 11f, a value calculation unit 11g, and a settlement unit 11h by executing a program stored in the storage unit 13. The control unit 11 is composed of integrated circuits such as an ASIC (Application Specific Integrated Circuit) and an FPGA (Field Programmable Array).

[0039] In such a configuration, the transmission / reception control unit 11a controls the transmission and reception of data with the user terminal 2, the corporate server 3, etc. via the communication unit 12. For example, the transmission / reception control unit 11a functions as a receiving unit that accepts requests to purchase NFTs from the user terminal 2 and a service application request from the corporate server 3 via the communication unit 12, and as a transmitting unit that transmits various notifications to the user terminal 2 and the corporate server 3, and controls various transmissions and receptions.

[0040] The digital twin management unit 11b generates a digital twin based on image data and specification data related to equipment for a decarbonized society transmitted from the corporate server 3, and registers and manages the digital twin in the digital twin memory unit 16.

[0041] More specifically, as shown in FIG. 2(b), the NFT management unit 11c has an NFT issuing unit 11c-1, an NFT registration unit 11c-2, and a transaction execution unit 11c-3. The NFT issuing unit 11c-1 reads a digital twin from the digital twin storage unit 16 and issues an NFT based on the digital twin on the blockchain 5. The NFT registration unit 11c-2 links the issued NFT with an NFT ID, registers it in the NFT storage unit 17, and manages it. As a result, the NFT is shared by the management server 1 and multiple nodes of the blockchain 5, and is managed in a distributed ledger in an unalterable state. For example, when a request for the transfer of ownership of an NFT is made by a user who is a purchaser, the transaction execution unit 12c-3 works on a smart contract of the blockchain 5 to execute a transaction such as the transfer of ownership.

[0042] The marketplace management unit 11d provides a marketplace related to the buying and selling of NFTs and manages its operation. Specifically, the marketplace presents purchasable NFTs to users along with transaction information such as their value, and manages the transactions. The user terminal 2 utilizes the marketplace as a web service through a web browser function, or by installing an application program for conducting transactions, as will be described in detail later.

[0043] The transaction processing unit 11e processes transactions based on requests from the company server 3 to apply for the service and requests from the user terminal 2 to purchase NFTs, updates the registration information in the storage unit 13, and transmits notifications regarding transaction completion and the like to each party. For example, when the transaction processing unit 11e receives a request from the company server 3 to apply for the service, it updates the registration information (transaction history information, etc.) in the company information storage unit 15 and the registration information in the transaction information storage unit 19. On the other hand, when the transaction processing unit 11e receives a request from the user terminal 2 to purchase NFTs, it appropriately updates the registration information (transaction history information, etc.) in the user information storage unit 14 and the registration information in the transaction information storage unit 19. The transaction processing unit 11e is responsible for processing various transactions, such as purchase, sale, resale, and auction of NFTs on the marketplace.

[0044] As shown in FIG. 2(c), the management unit 11f includes a cell management unit 11f-1, an equipment NFT management unit 11f-2, and an equipment management unit 11f-3. The cell management unit 11f-1 further includes a status management unit 11f-1a and an index image management unit 11f-1b. The equipment NFT management unit 11f-2 further includes a cheer information management unit 11f-2a and a donation information management unit 11f-2b. The equipment management unit 11f-3 further includes an operation amount management unit 11f-3a and a CO2 reduction power management unit 11f-3b.

[0045] In the cell management unit 11f-1, the status management unit 11f-2 identifies a status related to the cell's CO2 reduction activities based on the amount of CO2 reduction calculated by the calculation unit 11g from the operation information, and updates and manages the registered information in the management information storage unit 18. In this example, the status is assumed to have three stages: "initial state (CO2 full state)", "CO2 reduction in progress", and "carbon neutrality achieved", but is not limited to these. The index image management unit 11f-1b updates and manages the registered information in the management information storage unit 18 for index images such as a digital certificate generated by the generation unit 11i each time the cell status is updated and a reward image generated when carbon neutrality is achieved.

[0046] In the facility NFT management unit 11f-2, the cheer number management unit 11f-4 manages cheer information such as the number of cheers, which are cheer notifications sent from NFT owners, for each cell, and at a predetermined timing updates the registered information in the management information storage unit 18. The donation amount management unit 11f-5 updates the registered information in the management information storage unit 18 based on donation information such as the donation amount associated with the cheers from the NFT owner calculated by the calculation unit 11g.

[0047] In the equipment management unit 11f-3, the operation amount management unit 11f-1, under the control of the transmission / reception control unit 11a, receives operation information from the relay server 4 via the communication unit 12, and updates and manages the registered information in the management information storage unit 18 based on the operation information. The CO2 reduction power management unit 11f-3 updates and manages the registered information in the management information storage unit 18 based on the CO2 reduction power (kg / day) of the cell calculated by the calculation unit 11g from the operation information.

[0048] The calculation unit 11g calculates the amount of CO2 reduction and the CO2 reduction power of the cell from the operation information of the equipment related to the NFT, and calculates the donation amount according to the cheers from the NFT owner. Furthermore, the calculation unit 11g calculates the incentive (cheer points) for the user who sent the cheers, and updates the registration contents of the user information storage unit 14. The calculation rule for the cheer points can be set, for example, as 10% of the sales price of the NFT / 30 days as the base points, and in this example, only the base points are received from the 31st day after the purchase. However, the calculation rule is an example and is not limited to this. Users can use the cheer points appropriately, not just by receiving them, but by applying them to the purchase of another NFT or exchanging them for various external points.

[0049] Furthermore, at a predetermined timing, the calculation unit 11g reads out the registration information from the operation information storage unit 18, calculates the new value to be assigned to each NFT under a predetermined calculation formula based on the additional operation amount, etc., and updates the registration information (value history information) of the user who is the purchaser of the NFT by referring to the user information storage unit 14.

[0050] Since such processing is performed periodically, the user can check the current operating volume of the equipment corresponding to his / her NFT and the value returned from it at any time, thereby heightening the awareness that he / she is participating in efforts toward a decarbonized society. Note that "value" refers to any of points, miles, virtual currency, financial asset tokens, and in-service currency. Of course, the value calculation unit 11g may calculate value according to the asset value of the NFT, various campaigns, etc. in addition to the above operating information. More specifically, when calculating the value, it is also possible to change the rate depending on the region, or to change the rate according to the market demand and supply when there is an upper limit on the number of issuances.

[0051] The settlement unit 11h executes electronic settlement when an NFT transaction (e.g., purchase, etc.) is made. For example, when an NFT is purchased by the user terminal 2, the settlement unit 11h refers to the registration information (payment information) in the user information storage unit 14 to execute a withdrawal process for the purchase price, and executes a deposit process for the sales price to the company of the equipment related to the NFT. However, this is not limited to this. Generally, in the case of transactions on a blockchain, settlement is made via a wallet, but in this system, when the owner of the NFT is the operator, it is managed internally with respect to the user, so settlement can be made by general electronic settlement, which is convenient for the user.

[0052] When the cell achieves carbon neutrality, the generation unit 11i uses the geographical information of the cell and the achievement date and time as input to generate AI art (reward image; conceptually included in the index image) depicting the area (land) related to the cell, and generates a digital certificate (conceptually included in the index image) indicating the environmental contribution level according to the achievement level of the CO2 reduction goal. This generated index image is stored in the management information storage unit 18 as a part of the registration information.

[0053] The management server 1 can be composed of one or more servers. That is, for example, it is possible to distribute the processing by allocating the functions related to NFT management and the functions related to marketplace management to multiple servers.

[0054] FIG. 3 shows the configuration of a user terminal of the trading system, and will be described.

[0055] As shown in the figure, the user terminal 2 has a control unit 21, a communication unit 22, an operation unit 23, a display unit 24, and a storage unit 25. The units 21 to 25 are connected to each other via a bus line so as to be able to communicate with each other. The communication unit 22 is realized by, for example, a NIC or the like, and is a communication interface that is connected to a network 6 such as the Internet by wire or wirelessly and communicates with the management server 1 or the like. The operation unit 23 is realized by a mouse, a keyboard, or the like, and receives various operation inputs by a user. The display unit 24 is realized by a liquid crystal display or the like, and performs various displays. The operation unit 23 and the display unit 24 may be integrated into a touch panel. The storage unit 25 is realized by, for example, a semiconductor memory element such as a RAM or a flash memory, a HDD, an SSD, or the like, and stores application programs and the like executed by the control unit 21 consisting of a CPU, an MPU, or the like.

[0056] The control unit 21 has a web browser function and can execute transactions, such as purchasing NFTs, by utilizing the marketplace provided by the management server 1. Alternatively, by installing and executing an application program related to transactions, etc. in the storage unit 25, a transaction function is realized, and it becomes possible to execute various transactions, such as purchasing NFTs, by utilizing the marketplace provided by the management server 1.

[0057] Below, we will explain the processing flow related to the issuance of NFTs by the trading system, with reference to the flowchart of Figure 4.

[0058] When a request to apply for this service is made by the corporate server 3 (S1), the transmission / reception control unit 11a in the management server 1 accepts this application (S2). Then, in the management server 1, the digital twin management unit 11b generates a digital twin based on the image data and specification data related to the equipment for a decarbonized society transmitted from the corporate server 3 at the time of application, and registers the digital twin in the digital twin storage unit 16 (S3).

[0059] Next, in the management server 1, the NFT management unit 11c issues an NFT. More specifically, the NFT issuing unit 11c-1 reads the digital twin from the digital twin storage unit 16 and issues an NFT based on the digital twin on the blockchain 5. The NFT registration unit 11c-2 links the issued NFT with an NFT ID, registers it in the NFT storage unit 17, and manages it (S4, S5). As a result, the NFT is shared by the management server 1 and multiple nodes of the blockchain 5, and is managed in a distributed ledger in a non-tamperable state (S6).

[0060] Next, a process flow related to trading of NFTs by the trading system will be described with reference to the flowchart in Fig. 5. Here, the purchase of NFTs will be described as an example.

[0061] On the display screen of the user terminal 2, the user can check the digital twins and purchase conditions of facilities for a decarbonized society that can be purchased. That is, a list of facilities for a decarbonized society for which NFTs can be purchased is displayed on the screen, and the user can switch between the facilities and check them in order by swiping the upper area of ​​the screen. Then, once the facility that the user is considering purchasing has been decided, the user can check the purchase conditions such as the price and the operating history of the facility on the screen.

[0062] Once the desired equipment, etc. is determined and a purchase instruction is given, a purchase application request is made from the user terminal 2 (S11). Then, in the management server 1, the transmission / reception control unit 11a accepts this application (S12). Next, in the management server 1, the transaction processing unit 11e executes processing related to the purchase and updates the registered information in the storage unit 13 (S13). More specifically, the transaction history information, etc. in the user information storage unit 14 is updated, and the registered information in the transaction information storage unit 19 is updated.

[0063] In the management server 1, the settlement unit 11h executes settlement processing associated with the NFT purchase (S14), and the transaction processing unit 11e sends a notification of transaction completion to the user terminal 2 (S15). The user terminal 2 receives the notification via the communication unit 22, and under the control of the control unit 21, displays the notification content on the display unit 24, allowing the user to confirm that the purchase has been completed (S16).

[0064] The above describes the process flow for purchasing NFTs, but the transaction processing unit 11e also executes the process for reselling and auctioning NFTs in a similar manner. For example, in the case of an auction, the user who bids the highest price during a specified bidding period is permitted to purchase the item, and the process is executed in the above-described manner.

[0065] Next, the flow of processing related to browsing of management information related to a cell by the trading system will be described with reference to the flowchart of FIG.

[0066] When a cell for which confirmation of results is desired is selected on the initial screen of the user terminal 2, the control unit 21 transmits a request to view management information to the management server 1 (S21). In the management server 1, the transmission / reception control unit 11a receives this request (S22), and the management unit 11f extracts management information related to the cell from the management information storage unit 18 (S23).

[0067] In more detail, the operation amount management unit 11f-3a extracts the operation capacity of the equipment linked to the NFT, the CO2 reduction power management unit 11f-3b extracts the CO2 reduction power, the status management unit 11f-1a extracts the status related to CO2 reduction, the cheer information management unit 11f-2a extracts the number of cheers related to the cell, and the donation information management unit 11f-2b extracts the donation amount.

[0068] Next, the generation unit 11i generates display data related to the management information extracted by the management unit 11f (S24), and the transmission / reception control unit 11a transmits the display data to the user terminal 2 via the communication unit 12 (S25). In the user terminal 2, under the control of the control unit 21, the management information related to the identified cell on the map is displayed on the display unit 24 so that it can be confirmed (S27). In this way, the process related to viewing the management information is completed.

[0069] Here, the management information viewing screen displayed on the user terminal 2 is, for example, as shown in Fig. 8. As shown in the figure, the specified cell is highlighted on the map, and below that, the latitude, longitude, address, status, CO2 reduction power, number of cheers, donation amount, etc. of the equipment in the cell are displayed. If corporate PR has been set for this specified cell, the logo of the company supporting the cell is displayed and a link is added, as shown in Fig. 9. Furthermore, if a specific campaign has been set, details of the campaign are displayed, as shown in Fig. 10.

[0070] Therefore, it will be possible to check the track record of CO2 reduction efforts on a cell-by-cell basis, and it will also be possible to act as a bridge between companies and other entities rooted in the cell (region) and NFT owners, with the hope that collaboration will accelerate the realization of a carbon-free society.

[0071] Next, the flow of processing related to the generation of an index image according to the amount of CO2 reduction of a cell by the trading system will be described with reference to the flowchart of FIG.

[0072] In the management server 1, depending on the cell's status (e.g., carbon neutrality achieved), the generation unit 11i converts the cell's latitude and longitude into an address (S31), acquires environmental information such as the season and weather at that address (S32), includes the address and environmental information in a prompt and converts the scene into text by the generation system AI (S33), and includes this textualized scene in the prompt and generates an index image by the image generation AI (S34). Thus, the process related to the index image generation is completed.

[0073] An example of this generated index image is shown in Figures 11 and 12. That is, in the initial state, the cell's evaluation is presented by a member passport image as shown in Figure 11, and then, as CO2 reduction progresses, an index image as shown in Figure 12 is generated and presented by the above process. Therefore, by switching this index image, the user can realize the achievements of CO2 reduction of the cell they are supporting, which increases their motivation for support and accelerates efforts toward a decarbonized society as a whole.

[0074] As described above, according to the embodiment of the present invention, the following effects are achieved.

[0075] That is, according to an embodiment of the present invention, there is provided a trading system including a management server 1 and a blockchain 5, in which the management server 1 communicates with a user terminal 2 and a corporate server 3, issues non-fungible tokens on the blockchain 5 for digital twins generated based on at least equipment information transmitted from the corporate server 3, executes transactions related to the non-fungible tokens with the user terminal 2, manages the non-fungible tokens in association with cells obtained by subdividing a region into predetermined units, identifies the degree of achievement of CO2 reduction targets based on operation information of the equipment related to the non-fungible tokens transmitted from the corporate server 3, and includes a control unit 11 that generates an index image that indexes the cell according to the degree of goal achievement.

[0076] Here, in the management server 1, the control unit 11 accepts support notifications (cheers) for fungible tokens sent from the user terminal 2, manages them as the number of support notifications (cheers) for cells related to non-fungible tokens, and may also calculate and grant incentives to the user terminal 2 for sending the support notifications.

[0077] Furthermore, in the management server 1, the control unit 11 identifies management information including the CO2 reduction status and the number of supporters (yells) corresponding to the cell identified by the user terminal 2, and transmits display data related to the management information to the user terminal 2. If an advertisement for a specified company or a specified local government itself is associated with the cell, the advertisement may be included in the display data.

[0078] Therefore, it will be possible to trade NFTs issued for digital twins of facilities and other equipment aimed at a decarbonized society, and value will be assigned to the purchaser based on the operating status of the equipment after the transaction, making it possible to make general consumers part of the effort toward a decarbonized society, raising awareness, and providing society with a system that benefits companies, users, and operators alike.

[0079] In particular, it will be possible to subdivide an area into specified units using cells on the map and visualize the results of efforts toward a decarbonized society for each cell, which will increase the motivation of companies with roots in the area and users who have an emotional attachment to the area, thereby further promoting their efforts.

[0080] Furthermore, digital twins can also include content from anime and game characters, making it possible to reach a wide range of users depending on the selection.

[0081] Although the embodiment of the present invention has been described above, it goes without saying that the present invention is not limited to this embodiment and various improvements and modifications can be made without departing from the spirit and scope of the present invention.

[0082] For example, we can expect the expansion of services by combining it with regional revitalization (hometown tax donations), the possibility of linking digital twins with Japanese anime and game characters, and the ability to target facilities around the world. [Explanation of symbols]
