Description

Carbon emission credit-based security token server according to carbon reduction events, method and computer-readable recording medium {SERVER, METHOD AND COMPUTER-READABLE STORAGE MEDIUM FOR PROVIDING SECURITY TOKEN BASED ON CARBON CREDIT}

Embodiments of this document relate to a server, method, and computer-readable recording medium for obtaining proof data for a carbon reduction event and paying carbon emission credit-based security tokens to users based on this.

Currently, the world is implementing a gradual reduction in carbon emissions, one of the main causes of global warming, through the Kyoto Protocol. Obligatory countries or companies under the Kyoto Protocol set limits on carbon emissions for each period, and are required to sell carbon emissions rights for excess emissions.

Here, carbon emissions rights are a concept that encompasses quotas and credits. Quota refers to carbon emission rights granted to major carbon emission sources, such as power generation facilities or production facilities, equal to the total amount of carbon emissions determined within a country or region. Credit is a certificate showing that carbon emissions have been reduced compared to the standard projection for a carbon reduction project, and refers to an emission right paid to the project. According to the protocol, obligatory countries or companies can receive new allocations of carbon emissions credits in recognition of their reduction performance by investing in carbon emissions reduction projects.

Accordingly, mandatory countries or companies are encouraging the reduction of carbon emissions, and efforts are underway to reduce carbon emissions by providing incentives for various actions to reduce carbon emissions.

Meanwhile, efforts are being made at the individual level to reduce carbon emissions by using non-carbon-emission transportation methods such as walking, bicycles, and quickboards, but these individual efforts are not adequately compensated.

Currently, 'companies' are recognized for their carbon emissions reduction performance, but there is no protocol provision to 'individuals' for their carbon emissions reduction performance. Therefore, it is difficult for individuals to receive compensation for their efforts to reduce carbon emissions, and it is also difficult to accurately measure the amount of carbon they have reduced.

For example, the communication network may include wired and wireless communication networks such as local area network (LAN), wide area network (WAN), virtual network, and remote communication.

The blockchain network 20 is a peer-to-peer network that includes nodes that are multiple computing devices. Each node is a computing device that includes one or more processors, can perform computations, and can have blockchain account information registered in the blockchain network 20. Blockchain account information may include private keys and public keys. The private key can function as the user's digital signature to allow transactions to occur in the blockchain network 20. The public key is information that identifies each node and can function as a blockchain account address that holds cryptocurrency or tokens.

Each node included in the blockchain network 20 verifies, executes, and records transactions generated by other nodes according to the protocol established within the blockchain network 20, and rewards them (e.g., cryptocurrency, tokens, etc.) ) can be received.

A transaction is information that is propagated to nodes in the blockchain network 20 to add information to the blockchain or to cause a specific operation to occur within the blockchain network 20. For example, a transaction may include information for executing operations related to the issuance of tokens and operations related to the transfer of tokens. As an example, a transaction for transmitting a token from a first node to a second node includes account information of the first node, account information of the second node, token information, token quantity, signature information of the first node, and transfer information. It may include information that you wish to be recorded with.

When a transaction occurs, the transaction is verified based on the consensus algorithm (e.g. POW, POS, DPOS, etc.) specified in the blockchain network 20, and the verified block is connected to the previously created block (=transaction record). , the details of the newly connected block can be propagated to other nodes.

Information about blocks can be stored in the blockchain, a transaction database shared by nodes. Blockchain can be understood as a distributed ledger in which multiple nodes share the same information. Nodes can check the transaction processing results and records by querying the blockchain.

The blockchain network 20 according to one embodiment may issue a security token that specifies carbon emissions. A security token refers to a token (STO, security token offering) issued by linking real assets or financial assets to a blockchain-based distributed ledger using blockchain technology.

The blockchain network 20 according to one embodiment may issue a security token linked to a specific carbon emission certificate (ex. carbon emission certificate). The value of the security token according to one embodiment may be set to be pegged to the market price of the carbon emission certificate linked at the time of issuance, and the total value may be divided depending on the quantity of the security token issued. For example, if the number of tokens issued for a specific carbon emission certificate is 100, and the market price of the carbon emission certificate is 100,000 won at a specific time, the value of one token at that time is 100,000/100 = 1,000 won, Carbon credits can be pegged to real-time prices. In the above description, the operation performed by the blockchain network 20 can be understood as an operation performed by any one node (100n, 200n, 300n) included in the blockchain network 20.

The system 10 according to one embodiment may perform an operation of issuing a security token specifying a carbon emission credit, or an operation of paying a security token specifying a carbon emission credit, through the configuration illustrated in FIG. 2. .

The server 100 may calculate the amount of carbon reduced by the operator of the platform service by performing certain activities or providing the platform service to users and issue a security token for the allocated carbon emission rights. The server 100 may provide a service that pays carbon emission certificate-based security tokens as compensation for carbon reduction events performed by users of the platform service. Carbon reduction events may include various events that reduce carbon emissions. For example, carbon reduction events may include various events that can be recognized as reducing carbon emissions, such as moving by replacing carbon-emitting means and second-hand transactions.

The user terminal 200 may include a user terminal that uses the platform service provided by the server 100. As an example, the user terminal 200 may transmit proof data for a carbon reduction event performed by the user to the server 100 and receive a security token from the server 100. Proof data may include information about carbon reduction events performed by the user. For example, it may include information about the distance traveled by the user, information about the user's transaction history, etc.

The contract server 300 may include a server that operates to interact with the server 100 through a contract. For example, the contract server 300 may include a server operated by a company that guarantees payment of cash or compensation for points used by the user at the affiliated store 350 of the contract server 300. The contracting company issues cards or points such as check cards, credit cards, member-only cards, digital cards, and barcodes to users, and guarantees the money details paid by the user through points (or mileage) at the affiliated store 350, so that the user It can play the role of transferring the actual payment amount (ex. cash) to the affiliated store (350) (ex. card company).

An affiliated store 350 is a store that handles contract company points (ex. check card, credit card, member-only card, points, mileage, barcode, etc.) provided by the contract server 300 through a contract with the entity of the contract server 300. May include stores. The contract server 300 can issue contract company points that can be used like cash to the user, and when the user uses the contract company points at the affiliated store 350, it guarantees cash payment to the card affiliated store 350 for the amount of the contract company points used. can do.

The carbon emission certification agency 400 may include a platform that grants carbon emission credits by verifying or certifying data containing details of the server 100's contribution to reducing carbon emissions. The carbon emission certification agency 400 may include a platform that relays carbon emission trading. For example, the carbon emissions certification agency 400 may include an emissions trading market or an emissions trading certification agency certified to allow trading of carbon emissions credits between individuals or companies. The server 100 can obtain carbon emissions credits through the carbon emissions certification agency 400 using the verification data obtained from the user terminal 200. For example, the server 100 may obtain carbon emissions rights from the carbon emissions certification agency 400 by receiving certification data showing reduction performance generated by carrying out a carbon emissions reduction project in accordance with the Kyoto Protocol.

Investors/creditors 500 may include entities that share the profits of the server 100. For example, investors may include shareholders who invest and own shares so that the operator of the server 100 can operate the service. For example, the creditor may include a creditor who supports the operator of the server 100 to operate the service and thus regards the operator of the server 100 as a debtor. The investor/creditor 500 may hold a sales receivable, which is the right to receive a portion of the profits generated by the operator of the server 100 operating the service. In this document, the term 'sales receivable' may include not only forms in the form of bonds, but also various forms of contracts with provisions for paying operating profits of the server 100 to investors/creditors. In this document, for convenience of understanding, various contract types will be described collectively under the term 'sales receivable'. According to the above-mentioned meaning of 'sales receivable', the 'investor' corresponds to a 'creditor' who receives a portion of the profits of the server 100 through the sales receivables. Therefore, in the description below, 'investor' and 'creditor' are used. We will all refer to them collectively as ‘creditors’.

The token exchange 600 may include a server of a cryptocurrency exchange where security tokens are traded according to an embodiment.

Hereinafter, various embodiments of the configuration and operation of the server 100 operating in the system 10 according to an embodiment will be described.

Figure 3 is a functional block diagram of the server 100 according to one embodiment.

Referring to FIG. 3, the server 100 according to one embodiment may include a memory 110, a processor 120, an input/output interface 130, and a communication interface 140.

The memory 110 is supplied from external devices (e.g. user terminal 200, contract server 300, affiliated store 350, carbon emission certification agency 400, investor/creditor 500, token exchange 600, etc.). You can save acquired data or data you create yourself. The memory 110 may store instructions that can perform operations of the processor 120. For example, the memory 110 may store various data necessary to perform operations according to embodiments that will be described later.

The processor 120 may control the overall operation of the server 100. The processor 120 may execute instructions stored in the memory 110. The operation of the server 100 according to the embodiment of this document may be understood as an operation performed by the processor 120.

The input/output interface 130 may include a hardware interface or a software interface that allows the manager controlling the server 100 to input specific information or output specific information to the manager.

The communication interface 140 allows the server 100 to connect external devices (e.g., user terminal 200, contractor server 300, affiliated store 350, carbon emission certification agency 400, investor/creditor 500) through a communication network. , token exchange (600, etc.) allows information to be transmitted and received. To this end, the communication interface 140 may include a wireless communication module or a wired communication module.

The server 100 may be implemented as various types of devices that can perform calculations through the processor 120 and transmit and receive information through a network. For example, the server 100 may be implemented as a portable communication device, smart phone, computer device, portable multimedia device, laptop, tablet PC, etc.

The server 100 according to one embodiment performs operations up to issuing a security token specifying a carbon emission certificate (ex. the first embodiment of FIG. 4) or specifies a carbon emission certificate through the configuration illustrated in FIG. 3. After issuing a security token, a distribution operation (ex. the second embodiment of FIG. 7) can be performed.

Figure 4 is a flowchart of operations performed by the server 100 according to the first embodiment. The operation of the server 100 according to the embodiment of FIG. 4 may be understood as an operation performed by the processor 120.

In step S1010, the server 100 may obtain information about a carbon reduction event generated by a certain platform service.

The operating entity of the server 100 may be the same as the operating entity that operates the platform service. In this case, the server 100 can directly access information on the platform service.

The operating entity of the server 100 may be different from the operating entity that operates the platform service. In this case, the server 100 can access the information of the platform service according to the consent of the operator of the platform service.

Platform services may include services that directly or indirectly induce users to take actions to reduce carbon emissions by using an online platform or application. For example, platform services may include a used transaction relay service, a travel distance analysis service, a user's exercise information analysis service, etc.

Carbon reduction events may include events that contribute to reducing carbon emissions through platform services. For example, a carbon reduction event may include various events in which platform users reduce carbon emissions by using platform services (e.g., completing a used transaction). A carbon reduction event generated by a platform user may be regarded as a carbon reduction event generated by the operator of the platform service, or the rights may be transferred, in accordance with certain conditions (e.g. user consent, subscription terms, etc.). Additionally, carbon reduction events may include various events carried out by the platform operator to directly reduce carbon emissions.

According to one embodiment, the carbon reduction event may include information about used goods transaction details that occurred in the platform service (ex. FIGS. 5, 6, 10, 11, and 12). For example, the used transaction history may include information about the product that has been the subject of a used transaction, information about the time the seller acquired the product, the time when the used transaction of the product occurred, and information about the used transaction price of the product. For example, information about the time the product was acquired may include information about the time the seller purchased a new product, the time the product was produced, the time the product was released, and the time the seller purchased a used product.

According to one embodiment, the carbon reduction event may include the user's movement information or driving information (ex. FIGS. 8 and 9) determined using the platform service.

In step S1020, the server 100 may determine the amount of carbon reduction reduced by the operator of the platform service based on information about the carbon reduction event. In step S1020 described above, the server 100 determines the carbon reduction amount reduced by the user based on information about the carbon reduction event, and determines the user's carbon reduction amount according to predetermined conditions (e.g. user consent, subscription terms, etc.). Actions that are considered to be carbon reductions reduced by the operator of the platform service may also be included.

As an example, the server 100 determines the first amount of carbon reduced by a carbon reduction event, determines the second amount of carbon emitted by the operation of the platform service, and subtracts the second amount of carbon from the first amount of carbon. Thus, the amount of carbon reduction can be determined. For example, the server 100 subtracts the total second carbon amount emitted by operation during a specific period from the total first carbon amount reduced by a carbon reduction event that occurred during a specific period, thereby providing the carbon reduction amount during the specific period. can be determined.

If the carbon reduction event is a used transaction, the used transaction can be considered to be able to reduce carbon emissions emitted during the production, use, and disposal of a specific article because it can prevent the duplicate use of a specific article. In other words, one used transaction replaces the use of two new products with the use of one used product, so when a used transaction is completed, carbon emissions due to the use of new products can be considered to be reduced.

Accordingly, when calculating the amount of carbon reduction due to second-hand transactions, from the perspective of the buyer of used goods, carbon emissions generated by the product are reduced during the period of use before the second-hand transaction, so the period of use before the second-hand transaction is based on A method of determining the amount of carbon reduction can be considered. In addition, from the perspective of the seller of used goods, since the carbon emissions generated by the goods are reduced during the remaining life of the goods after the second-hand transaction, a method of determining the amount of carbon reduction based on the remaining life of the goods after the second-hand transaction is used. can be considered. Accordingly, an embodiment in which the server 100 determines the carbon reduction amount according to each viewpoint will be described below with FIGS. 5 and 6.

Figure 5 is a first example diagram for explaining the operation of determining the carbon reduction amount due to second-hand transactions based on the basic carbon emission amount generated by one product when determining the carbon reduction amount according to the first embodiment.

The embodiment of FIG. 5 may include an operation in which the server 100 determines the amount of carbon reduction due to second-hand transactions based on the ratio of the seller's usage period to the lifespan of the second-hand transaction. For example, as shown in Equation 1 below, the server 100 is based on a value corresponding to the ratio of the period of use of the article to the lifespan of the used article in the basic carbon emissions generated by the used and traded article. The amount of carbon reduction can be determined.

[Equation 1]

Basic emissions refer to the amount of carbon a product emits during a specific period of time. For example, basic emissions may include carbon emissions emitted during at least one of the product production, use, and disposal processes. For example, the base emissions can be determined based on the CO2 emissions of the article as recorded in the LCI database.

Product life refers to the lifespan over which the product is used. Information about product life can be measured by various methods. For example, the product lifespan may be determined based on a database recorded in the Korea Goods Management Act.

The period of use may include the period during which the product was used by the seller who posted the used transaction on the platform service.

Meanwhile, the method of obtaining the above-mentioned 'basic emissions, product life, and usage period' is a value that the operator of the server 100 can consider as 'basic emissions, product life, and usage period' by referring to the embodiments of this document. Various methods can be applied to find . In addition, the scope of rights for 'basic emissions, product life, and use period' stated in the claims of this document also include factors derived by various methods that can be seen as applying the concept of 'basic emissions, product life, and use period' described above. It can be included.

Referring to Figure 5, the first carbon reduction amount according to the carbon reduction event that occurred at the time of the first used transaction can be calculated as follows.

According to Figure 5, when the basic emissions of a specific product are 100%, the lifespan is 100 months, and the period of use until the first used transaction is 25 months, the primary carbon reduction amount can be calculated as 25% according to Equation 1. You can. That is, if the basic emission value of the product is 500 (unit omitted), the server 100 may determine the first carbon reduction amount to be 125 (unit omitted). At this time, since the seller in the first used transaction purchased the product while it was new, the server 100 can determine the period of use from the time the seller acquired the new product to the time the used transaction of the product was completed. For example, the server 100 stores the seller's product based on any one of the information about the time of purchase of a new product entered by the seller during a used transaction, the time of production that can be confirmed from the product, and the information about the product release time that can be confirmed from the product. The acquisition time can be determined. For example, the server 100 may determine the time when a used transaction of an item occurred based on information about the time when the sale of a post specifying a used transaction in a platform service was completed.

Again, referring to Figure 5, the secondary carbon reduction amount according to the carbon reduction event that occurred at the time of the secondary used transaction can be calculated as follows.

According to Figure 5, when the basic emission rate of a specific product is 100%, the lifespan is 100 months, and the usage period from the first used transaction to the second used transaction is 50 months, the secondary carbon reduction amount is Equation 1 Depending on this, it can be calculated as 50%. That is, if the basic emission value of the product is 500 (unit omitted), the server 100 may determine the first carbon reduction amount to be 250 (unit omitted). Since the seller in the secondary used transaction purchased the product while it was a used product, for example, the server 100 may determine the period of use from the time the seller acquired the used product to the time the used transaction of the product was completed. For example, the server 100 may determine the seller's acquisition time of the goods based on any one of the information of the time the seller purchased the used goods entered during the used goods transaction and the used goods transaction time that can be confirmed from the past used goods transaction history of the platform. You can. For example, the server 100 may determine the time when a used transaction of an item occurred based on information about the time when the sale of a post specifying a used transaction in a platform service was completed.

According to the embodiment of FIG. 5 described above, the server 100 filters the used transaction details that occurred in the platform service based on settings for a predetermined time range or the type (or category) of the product, and provides carbon for the filtered details. The amount of reduction can be calculated.

For example, the server 100 applies the above-described calculation process to the used transaction history filtered by the product type called “mobility item” during the “period from January 1, 2020 to December 31, 2020” The first carbon amount reduced can be determined. Additionally, the server 100 may determine the second amount of carbon emitted by the operation of the platform service for the set time range and type of product. For example, the server 100 calculates the second amount of carbon emitted by the operation of the platform service based on the number of carbon emissions per used transaction that occurs while operating the platform service multiplied by the number of filtered used transaction details. can be determined. For example, the server 100 converts the power usage and fossil fuel consumption that occurred during the “period from January 1, 2020 to December 31, 2020” into carbon emissions, and then converts the “converted carbon emissions” into carbon emissions. You can calculate the carbon emissions per transaction by dividing the figure by the “number of used transactions for mobility items that occurred during the period from January 1, 2020 to December 31, 2020.” The server 100 may determine the carbon reduction amount for the filtered details by subtracting the second carbon amount from the first carbon amount.

According to the above-described embodiment of FIG. 5, there is an advantage that even at the point when a secondary used transaction occurs, the amount of carbon reduction can be determined by considering the actual period of use of the used article by the owner of the used article at the time.

Figure 6 is a second example diagram for explaining the operation of determining the carbon reduction amount due to second-hand transactions based on the basic carbon emission amount generated by one product when determining the carbon reduction amount according to the first embodiment.

The embodiment of FIG. 6 may include an operation in which the server 100 determines the amount of carbon reduction due to second-hand transactions based on the ratio of the seller's remaining lifespan to the lifespan of the second-hand transaction. For example, as shown in Equation 2 below, the server 100 calculates the basic carbon emissions generated by the used and traded article to a first value corresponding to the ratio of the remaining life of the article to the life of the used and traded article. The amount of carbon reduction can be determined by considering the probability of duplicate transactions of goods occurring.

[Equation 2]

Basic emissions refer to the amount of carbon a product emits during a specific period of time. For example, basic emissions may include carbon emissions emitted during at least one of the product production, use, and disposal processes. For example, the base emissions can be determined based on the CO2 emissions of the article as recorded in the LCI database.

Product life refers to the lifespan over which the product is used. Information about product life can be measured by various methods. For example, the product lifespan may be determined based on a database recorded in the Korea Goods Management Act.

Remaining life refers to the remaining life of the product. For example, the remaining life can be calculated by subtracting the total period of use of the product from the product lifespan.

is a real number that takes into account the probability of duplicate transactions of goods occurring, and can be greater than 0 and less than or equal to 1. for example, is the ratio of the period of use of the article to the remaining life of the article can be decided. However, from the point where the period of use becomes longer than the remaining lifespan, Since it exceeds 1, in this case can be fixed to the value of 1.

Meanwhile, the method of obtaining the above-mentioned 'basic emissions, product life, remaining life' is a value that the operator of the server 100 can consider as 'basic emissions, product life, and remaining life' by referring to the embodiment of this document. Various methods can be applied to find . In addition, the scope of rights for 'basic emissions, product life, and remaining life' described in the claims of this document also include factors derived by various methods that can be seen as applying the concept of 'basic emissions, product life, and remaining life' described above. It can be included.

In addition, the above-mentioned ' 'The operator of the server 100 can refer to the embodiments of this document and use various methods to obtain a value that can be considered as the probability of duplicate transactions occurring. It can be applied.

Referring to Figure 6, the first carbon reduction amount according to the carbon reduction event that occurred at the time of the first used transaction can be calculated as follows.

According to Figure 6, when the basic emission rate of a specific product is 100%, the lifespan is 100 months, and the period of use until the first used transaction is 25 months, so the remaining lifespan is 75 months. However, a secondary used transaction may occur during the remaining 75 months of life, and if a secondary used transaction occurs, the calculation method according to the embodiment of FIG. 6 calculates the first reduction amount and the second reduction amount in duplicate. In addition, at the point when the first used transaction occurs, the future point in time when the second used transaction will occur cannot be specified, so duplicate figures cannot be known. Accordingly, in the embodiment of FIG. 6, the factor considering the probability of duplicate transactions of goods occurring is Use . At this time go If defined as, = 25/75 = corresponds to 1/3. Therefore, the primary carbon reduction amount is calculated according to Equation 2: It can be calculated as = 25%. That is, if the basic emission value of the product is 500 (unit omitted), the server 100 may determine the first carbon reduction amount to be 125 (unit omitted).

Again, referring to Figure 6, the secondary carbon reduction amount according to the carbon reduction event that occurred at the time of the secondary used transaction can be calculated as follows.

According to Figure 6, when the basic emission rate of a specific product is 100%, the lifespan is 100 months, and the remaining lifespan is 25 months, the total use period until the second used transaction is 100-25 = 75 months. , the secondary carbon reduction amount is calculated according to Equation 2: = 25%. That is, if the basic emission value of the product is 500 (unit omitted), the server 100 may determine the second carbon reduction amount to be 125 (unit omitted).

According to the above-described embodiment of FIG. 6, the server 100 filters the used transaction details that occurred in the platform service based on settings for a predetermined time range or the type (or category) of the product, and provides carbon for the filtered details. The amount of reduction can be calculated.

For example, the server 100 applies the above-described calculation process to the used transaction history filtered by the product type called “mobility item” during the “period from January 1, 2020 to December 31, 2020” The first carbon amount reduced can be determined. Additionally, the server 100 may determine the second amount of carbon emitted by the operation of the platform service for the set time range and type of product. For example, the server 100 calculates the second amount of carbon emitted by the operation of the platform service based on the number of carbon emissions per used transaction that occurs while operating the platform service multiplied by the number of filtered used transaction details. can be determined. For example, the server 100 converts the power usage and fossil fuel consumption that occurred during the “period from January 1, 2020 to December 31, 2020” into carbon emissions, and then converts the “converted carbon emissions” into carbon emissions. By dividing the figure by “the number of second-hand transactions for mobility items that occurred during the period from January 1, 2020 to December 31, 2020,” you can calculate the carbon emissions per second-hand transaction. The server 100 may determine the carbon reduction amount for the filtered details by subtracting the second carbon amount from the first carbon amount.

According to the above-described embodiment of FIG. 6, even if used transactions occur repeatedly, the probability of duplicate transactions of goods occurring in various ways is considered. There is an advantage in that the amount of carbon reduction can be adaptively determined according to the type or characteristics of the product by utilizing the elements of .

Meanwhile, in step S1020, when the carbon reduction event includes the user's movement information (ex. FIGS. 8 and 9), an embodiment in which the server 100 determines the carbon reduction amount will be described later in the description of FIGS. 8 and 9. do.

In step S1030, the server 100 may acquire carbon emissions credits based on the amount of carbon reduction reduced by the operator of the platform service.

If the operating entity of the server 100 and the operating entity of the platform service are the same, the operation of step S1030 is to allow the server 100 to use the authentication data (ex. data generated in step S1020) required to obtain carbon credits. It may include an operation of sharing with the certification authority 400.

If the operating entity of the server 100 and the operating entity of the platform service are different, the operation of step S1030 involves the server 100 providing the platform service with the authentication data (ex. data generated in step S1020) required to obtain carbon emission credits. It may include an operation of sharing with the operating entity or with the carbon emission certification organization 400.

When carbon emissions rights are obtained in step S1030, the server 100 may issue a security token specifying the carbon emissions rights according to a second embodiment, which will be described later.

Figure 7 is a flowchart of operations performed by the server 100 according to the second embodiment. The operation of the server 100 according to the embodiment of FIG. 7 may be understood as an operation performed by the processor 120.

In step S2010, the server 100 may issue a security token specifying carbon emissions. For example, the server 100 may issue a security token specifying a carbon emission certificate (ex. carbon emission certificate) using the above-described blockchain network 20. The server 100 can set the value of the issued security token to be pegged to the real-time price of the carbon emission certificate linked to the security token. The value of one security token can be divided proportionally to the total value of the linked carbon credits, corresponding to the total number of issued security tokens. For example, if the number of tokens issued for a specific carbon emission certificate is 100, and the market price of the carbon emission certificate is 100,000 won at a specific time, the value of one token at that time is 100,000/100 = 1,000 won, Carbon credits can be pegged to real-time prices.

In step S2020, the server 100 may obtain proof data for a carbon reduction event performed by the user. For example, the server 100 may determine the amount of carbon reduction reduced by the user based on proof data.

In step S2030, the server 100 may pay the security token to the user based on the verification data. For example, the server 100 may provide the user with a quantity of security tokens corresponding to the market price of carbon emission rights whose value is proportional to the amount of carbon reduction saved, based on the amount of carbon reduction determined from the proof data.

Embodiments of steps S2020 and S2030 may be implemented in various embodiments of FIGS. 8 to 12 depending on the type of authentication data.

Figure 8 is an example diagram of data defining carbon emissions for each moving distance of a means of transportation according to the second embodiment. The embodiment of FIG. 8 may include an embodiment of determining the quantity of security tokens to be paid to the user according to the amount of carbon reduction determined by the user's movement information.

Referring to FIG. 8, the server 100 may previously store data on carbon emissions by travel distance for each carbon emission means of transportation. The proof data may include information about the distance traveled by the user. In step S2020, the server 100 may determine the amount of carbon emissions reduced according to the distance traveled by the user by replacing the carbon-emitting means of transportation based on the proof data. The server 100 may refer to pre-stored data and calculate the reduced carbon emissions according to the distance traveled by the user by replacing the carbon-emitting means of transportation based on the proof data transmitted by the user terminal 200.

As an example, the server 100 determines that if the distance traveled by the user by means of transportation that does not emit carbon (e.g. bicycle, walking) is more than 5km but less than 10km, it has replaced the subway, and if it is more than 10km, it has replaced the car. It may be preset to do so. Accordingly, if the proof data sent by the user includes information that the user traveled 7km by bicycle, it is determined that the user replaced the 7km by bicycle with a bicycle, and "carbon emissions per 1km of subway travel ( By calculating "60g) x 7km", it can be determined that carbon emissions have been reduced to '420g'.

In step S2030, the server 100 may provide the user with a quantity of security tokens corresponding to carbon emissions credits whose value is proportional to the saved carbon reduction amount, based on the determined carbon reduction amount of 420g. For example, if the carbon emission credit that can be allocated for '420g' of carbon reduction is 10,000 won, and the value of one security token specifying the carbon emission credit is 100 won, then 10,000/100 = 100 units. Security tokens can be paid to users.

In addition, if the proof data sent by the user includes information that the user traveled 100 km by means of transportation that does not emit carbon emissions (e.g. bicycle, walking), the user can replace the 100 km traveled by car with a bicycle, etc. By calculating "carbon emissions when a car moves 1km (200g) x 100km", it can be determined that carbon emissions for '20kg' have been reduced.

In step S2030, based on the determined carbon reduction amount, the server 100 may pay the user a quantity of security tokens corresponding to the carbon emission certificate market price with a value proportional to the saved carbon reduction amount. For example, if the carbon credit that can be allocated for '20 kg' of carbon reduction is 200,000 won, and the value of one security token specifying the carbon credit is 100 won, then 200,000/100 = 2,000 units. Security tokens can be paid to users.

On the other hand, if the means of transportation actually used by the user is a means of transportation that emits a small amount of carbon (e.g., a public bicycle, etc.), the carbon emissions generated by the use of the method of transportation (e.g., the carbon emissions emitted from the operation of one public bicycle) It can be calculated by subtracting from the carbon reduction amount.

Figure 9 is an example diagram for explaining an operation of determining the user's driving information and differentially paying compensation according to the user's movement information according to the second embodiment. The embodiment of FIG. 9 may include an embodiment of determining the quantity of security tokens to be paid by applying a differential ratio according to driving information to the amount of carbon reduction determined by the user's movement information. Here, 'driving information' may include various information that can affect the user's judgment of the amount of carbon reduction saved by using a mobile device. For example, if a user uses a public bicycle to replace a carbon-emitting means of transportation, carbon emissions are reduced compared to carbon-emitting transportation, but the operation of a public bicycle also generates carbon (e.g., collection of public bicycles). Because of the indirect carbon emissions caused by vehicles, these impacts must be taken into account. In addition, when a user uses a mobility device not only for the purpose of transportation itself, such as commuting to work, but also for purposes such as exercise or leisure, the national standard determines whether the purpose of driving such as exercise or leisure should be considered an act of reducing carbon emissions. It can be applied very differently. Therefore, the embodiment of Figure 9 presents a technology for determining 'driving information' that can affect the user's judgment of the amount of carbon reduction saved. The driving information in this document is exemplified as determining the type of mobility device used by the user or the driving purpose for which the user drove using the transportation device, but the embodiments of this document affect not only the exemplified information but also the determination of the amount of carbon reduction. It can contain a variety of information that can provide.

Referring to FIG. 9, the proof data may include movement information generated by the user while moving a predetermined distance. For example, movement information includes the user's identification information, the movement path the user moved using the movement device, the date and time of using the movement device, the travel time required for movement using the movement device, and the movement using the movement device. Distance traveled, user's past driving information (e.g. type of mobility device used, purpose of driving, etc.), user's current driving information (e.g. type of transportation device used, purpose of driving, etc.), amount spent to use the mobility device , may include information on the means of transportation replaced by using mobility devices, and the amount of money saved by replacing the transportation method.

For example, the movement information may include first movement information, which is the user's 'past' movement information, and second movement information, which is the user's 'current' movement information. In the description of the embodiment of FIG. 9, 'past' may include the time when reference data was generated to determine the user's driving information. In the description of the embodiment of FIG. 9, 'current' may include not only the real-time point in time, but also the point in time when data that is the target for determining the user's driving information is generated.

Hereinafter, in the description of the embodiment of FIG. 9, past information that serves as a reference for determining the user's driving information is referred to with the modifier 'first', and current information that is the target for determining the user's driving information is referred to as 'the first'. We will refer to it with the modifier '2'.

The server 100 may obtain and store first movement information, which is data generated when one or more users normally use a movement device. For example, the first movement information may include information about first driving information, a first movement path, and a first movement time.

In one embodiment, the second movement information acquired by the server 100 is the second driving information directly entered by the user ('second driving information' is information directly entered by the user at the current time and is not determined to be true or false. information) may be included. In this case, the server 100 can determine whether the second driving information entered by the user is true or false through an embodiment described later. If it is false, the server 100 may not reflect the data, request the user to re-enter it, or The operator of the server 100 can manually check whether the second driving information is correct.

In one embodiment, the second movement information acquired by the server 100 is the second driving information directly entered by the user ('second driving information' is information directly entered by the user at the current time and is not determined to be true or false. information that is not included) may not be included. In this case, the server 100 can directly determine the user's driving information through an embodiment described later.

As an example, the first movement information includes information on first driving information, a first movement path, and a first movement time acquired from the user, and the second movement information includes a second movement path and second movement obtained from the user. May contain information about time. In this case, the server 100 uses the first driving information included in the first movement information that has the highest similarity to the second movement path and second movement time included in the second movement information among the one or more pieces of first movement information as the second movement information. It can be determined from the driving information of the movement information. For example, the server 100 first filters the first movement information including the first movement path whose similarity to the second movement path is more than a preset rate among the first movement information, and first filters the first movement information. The first movement information including the first movement time whose similarity to the second movement time is equal to or higher than a preset rate is second filtered, and the driving information included in the second filtered first movement information is included at the highest rate. The information may be determined as driving information of the second movement information.

As an example, the first movement information includes information on first driving information, a first movement path, and a first movement time obtained from the user, and the second movement information includes a second movement path and a second movement time obtained from the user. May contain information about travel time. In this case, the server 100 uses the first movement information obtained from one or more users to generate a neural network learned to determine the first driving information based on information about the first movement path and the first movement time, , an operation of determining the user's driving information from the second movement information can be performed based on the generated neural network. For example, when the second movement information further includes second driving information input by the user, the server 100 compares the second driving information input by the user with the driving information determined based on the neural network, It is possible to determine whether the second driving information entered is true or false. If the second driving information and the neural network's driving information are different from each other, the server 100 determines it to be false and does not reflect the second driving information, requests the user to re-enter it, or causes the operator of the server 100 to determine the second driving information. You can manually check whether the information is correct or the output information of the neural network is correct.

Through the above-described operation, in step S2020, the server 100 can determine the amount of carbon reduction saved by the user and the user's driving information based on the movement information included in the authentication data.

As an example, the server 100 may determine the amount of carbon reduction by applying the second movement distance included in the user's second movement information to the carbon emission coefficient per movement distance of the transportation method replaced by the user based on the second movement information. You can. The server 100 may calculate and store the carbon emission coefficient per travel distance of the means of transportation as shown in Equation 3 below. Additionally, the transportation method replaced by the user can be determined by applying the embodiment of FIG. 8.

[Equation 3]

( : Carbon emission factor per travel distance of transport mode A (kgCO _2eq /km), : Basic emission coefficient according to type of transportation A (kgCO _2eq /TJ), : Net calorific value per liter by oil type (MJ/l), : Fuel efficiency by type when driving transportation A (km/l), : Weight according to population using each transportation method)

type Emission coefficient according to oil type gasoline 0.15871 (kgCO _2eq /km) via 0.19701 (kgCO _2eq /km) LPG 0.00198 (kgCO _2eq /km)

[ Example]

here, (Weight according to the population using each means of transportation) is a weight for calculating the amount of savings considering the case where there are multiple people using each means of transportation. For example, if the average population using one subway at the same time is 100, can be applied as 1 (number of users)/100 (average number of people using the subway) = 0.01. For example, the server 100 may apply the user's second travel distance to the carbon emission coefficient to calculate the carbon reduction amount as shown in Equation 4 below.

[Equation 4]

( : Carbon reduction (kgCO _2eq ), : Travel distance (km) traveled by the user by substituting transportation method A, : Carbon emission factor per travel distance of transport mode A (kgCO _2eq /km))

On the other hand, if the means of transportation actually used by the user is a means of transportation that emits a small amount of carbon (e.g., a public bicycle, etc.), the carbon emissions generated by the use of the method of transportation (e.g., the carbon emissions emitted from the operation of one public bicycle) It can be calculated by subtracting from the carbon reduction amount.

In step S2030, when paying security tokens to the user based on the determined carbon reduction amount, the server 100 may differentially set the payment rate of the security tokens according to driving information and pay them.

As an example, the server 100 may store the ratio to be applied to compensation according to each driving purpose. The server 100 may set compensation by applying the ratio mapped to the determined driving purpose to the determined carbon reduction amount. For example, if the driving information to be determined is the driving purpose, the driving purpose is commuting to work (ex. 100%), leaving work (ex. 100%), irregular travel purposes (ex. 90%), and leisure purposes (ex. 80%). ), exercise purpose (ex. 100%). At this _time , if the determined driving purpose is leisure and the determined carbon reduction amount _is 100 kgCO _2eq , in step S2030, the server 100 calculates _the carbon reduction amount as 90% Security tokens can be paid in a quantity corresponding to the value of the carbon emissions certificate that can be recognized.

Figure 10 is an example diagram for explaining an operation in which the server 100 determines the amount of carbon reduction based on information about the time when a used transaction occurred according to the second embodiment. The embodiment of Figure 10 includes an embodiment of determining the quantity of security tokens to be paid to users (ex. seller, buyer, relay entity, etc.) according to the amount of carbon reduction by second-hand transactions based on the 'time' of transaction occurrence. .

Referring to FIG. 10, the proof data may include information about used goods transactions. For example, the proof data may include information on the product that has been the subject of a used transaction, information on the subject who performed the used transaction, and information on the used transaction history (e.g. time or price) of the article, and the server 100 It is possible to determine the contribution of entities involved in second-hand transactions and the amount of carbon reduction caused by second-hand transactions. Product information may include information about the type of product, model name, year of production, year of purchase, new price of the product, used price, etc. Information on the entity that performed the used transaction may include seller information, buyer information, and information on the intermediate entity for the used transaction. For example, the intermediary entity for second-hand transactions may include various entities that assist with second-hand transactions, such as companies that provide websites that can perform second-hand transactions, and companies that store second-hand transaction items. Information about the time when a second-hand transaction of a product occurred may include time information based on various standards at which a second-hand transaction can be recognized as having been completed, such as the time when the product information was uploaded and the time the second-hand price of the product was deposited to the seller.

Referring to FIG. 10, in step S2020, the server 100 calculates the first carbon reduction amount based on the carbon emissions generated by the product after the time when the used transaction occurred, and the carbon emissions generated by the product before the time when the used transaction occurred. Based on this, the second carbon reduction amount can be calculated.

For example, the server 100 may generate a first carbon amount corresponding to the ratio of the amount of carbon emitted by use during the average life of the product from the time when the second-hand transaction of the product occurs to the time when the average life of the product ends, and the product. The first carbon reduction amount can be derived by adding up the second amount of carbon emitted upon disposal. In other words, the embodiment of this document is considered to be the first because the seller sells the product, thereby reducing the additional carbon emissions generated during the remaining life of the product and preventing the disposal of the product, thus reducing the carbon emissions generated when the product is disposed of. The amount of carbon reduction can be calculated. For example, the server 100 determines the amount of third carbon emitted during the production of the product and the amount of carbon emitted by use during the average life of the product, from the time the product was shipped or the first purchase occurred to the time when the second-hand transaction of the product occurred. The second carbon reduction amount can be derived by adding up the fourth carbon amount corresponding to the ratio. That is, in the embodiment of FIG. 10, the buyer purchases the product, thereby preventing additional production of new products, reducing carbon emissions generated during the production of the product, and reducing carbon emissions that would have been generated if a new product was purchased and used. By looking at it, the second carbon reduction amount can be calculated.

Hereinafter, an example of deriving the first to fourth carbon amounts will be described.

As an example, the server 100 may already store or obtain from the outside information on the average lifespan of the product, data defining the amount of carbon emitted when the product is used, the production time of the product, and the time of the seller's purchase of the product. For example, the server 100 may store the example information in Table 2 below as data defining the amount of carbon emitted when the product is used.

product emissions refrigerator 0.287 (tCO _2eq /unit) TV 0.374 (tCO _2eq /unit) washing machine 0.376 (tCO _2eq /piece) Smartphone 0.0389 (tCO _2eq /piece) laptop 0.171 (tCO _2eq /piece) desktop 0.223 (tCO _2eq /unit) tablet 0.0879 (tCO _2eq /unit) Gas range 0.176 (tCO _2eq /piece) electric range 0.176 (tCO _2eq /piece) Microwave 0.0581 (tCO _2eq /unit) coffee machine 0.0416 (tCO _2eq /unit) dish wash machine 0.143 (tCO _2eq /unit)

The server 100 may determine the first carbon amount based on data defining the average lifespan of the product, the amount of carbon emitted when the product is used, and the year of production or purchase time of the product. For example, as shown in Figure 10, the average lifespan of a specific product is 5 years, the carbon emissions when using the product during its average lifespan (5 years) are 3000 tCO ₂ , and the seller purchases the product and uses it for 1 year. , which corresponds to the ratio of the amount of carbon emitted by use during the average life of the product from the time when the second-hand transaction of the product occurred to the time the average life of the product ends (e.g., the year of production or the time of purchase plus the average life) The first carbon amount can be determined as (5-1)/5*3000 = 2400 tCO ₂ .

Meanwhile, depending on the embodiment, a fixed time may be applied to the time when a second-hand transaction occurs regardless of the actual second-hand transaction time. For example, the time when it is statistically determined that second-hand transactions begin to occur after a specific product is released can be fixedly applied as the time when second-hand transactions occur. For example, if product A begins to be traded as a used product one year after its release, when applying the above-described embodiment, the seller's usage period can be fixed to one year.

The server 100 can specify an item subject to used trade and determine the parts that make up the item, and the server 100 calculates the carbon emissions of the part by manufacturing weight according to data with defined carbon emissions. You can calculate the carbon footprint of manufacturing each part by multiplying its weight. For example, if the product is a bicycle, the server 100 specifies the material of the parts constituting the bicycle, and the server 100 calculates the carbon emissions of the specified parts according to data defining the carbon emissions by manufacturing weight. You can calculate the carbon footprint of manufacturing each part by multiplying its weight. Through this operation, the server 100 can determine the third carbon amount according to the manufacture of the bicycle by adding up the carbon emissions calculated for all identified parts.

As an example, the server 100 may store or obtain from an external source data defining the average lifespan of the product, the amount of carbon emitted when the product is used, and the year of production of the product. The server 100 may determine the fourth carbon amount based on data defining the average lifespan of the product, the amount of carbon emitted when the product is used, and the year of production of the product. For example, as shown in Figure 7, the average lifespan of a specific product is 5 years, the carbon emissions when using the product during its average lifespan (5 years) are 3000 tCO ₂ , and the seller purchases the product and uses it for 1 year. , the fourth carbon amount corresponding to the ratio of the amount of carbon emitted by use during the average lifespan of the product from the time of production, shipment, or first purchase of the product to the time of the second-hand transaction of the product is 1/5 * 3000 = 600 It can be determined by tCO ₂ .

The server 100 may determine the contribution of the subject involved in the used transaction data based on the first carbon reduction amount and the second carbon reduction amount. For example, referring to FIG. 10, the server 100 determines the first of the total carbon amount of 14000 tCO2 emitted by the seller during the production (10000 tCO ₂ ), use (3000 tCO ₂ ), and disposal (1000 tCO ₂ ) process of the product. Calculating that 1 carbon reduction (3400 tCO ₂ ) has been reduced, the seller's contribution can be determined as 3400/14000*100 = 24.3%. The server 100 saves the second carbon reduction amount (10600 tCO ₂ ) out of the total carbon amount of 14000 tCO2 emitted by the buyer during the production (10000 tCO ₂ ), use (3000 tCO ₂ ), and disposal (1000 tCO ₂ ) process of the product. By calculating this, the buyer's contribution can be determined as 10600/14000*100 = 75.7%.

In step S2030, the server 100 may be allocated through the sum of the first carbon reduction amount and the second carbon reduction amount based on the ratio of the first carbon reduction amount and the second carbon reduction amount or the ratio of the first contribution and the second contribution amount. A quantity of security tokens corresponding to the value of existing carbon emissions certificates can be distributed to sellers and buyers.

In another embodiment, the server 100 may further include the relay entity that relays the used transaction as an entity related to the used transaction, as shown in FIG. 11, and determine the amount of carbon reduction and contribution involved by the relay entity.

Figure 11 is an example diagram for explaining an operation in which the server 100 determines the contribution between the seller, the buyer, and the relay entity based on the second-hand transaction time according to the second embodiment.

Referring to FIG. 11, in step S2020, the server 100 may additionally determine the third carbon reduction amount saved by the relay entity providing a service for relaying used goods transactions. At this time, the relay entity may include the operator of the server 100. The relay entity may include a third relay entity that is separate from the server 100.

The server 100 can determine the extended life of the product compared to the average life of the product based on the information that the relay entity repaired the product, and calculate the amount of carbon saved by use during the extended life of the determined product. 3 It can be determined by the amount of carbon reduction. In other words, in the embodiment of this document, the third carbon reduction amount can be calculated by considering that the relay entity reduces carbon emissions by repairing the product and preventing the use of another third product for the period that extends the life of the product. . For example, as shown in Figure 9, when the average lifespan of a specific product is 5 years and the carbon emission when using the product during the average lifespan (5 years) of the product is 3000 tCO ₂ , the relay entity repairs the product to extend its lifespan. If it is determined that it has been extended by one year, the third carbon reduction amount saved by use during the extended life of the product can be determined as 1/(5+1)*3000 = 500 tCO2. In this case, as in the example of Figure 11, when calculating the seller's first carbon reduction amount and the buyer's second carbon reduction amount, the life of the product is calculated by adding the original life (5 years) to the extended life (1 year) to calculate the first carbon reduction. The reduction amount and secondary carbon reduction amount can be calculated.

In addition, the server 100 can determine the storage period until the relay entity receives the product from the seller and delivers the product to the buyer, and calculates the amount of carbon saved by use during the storage period of the determined product as the third carbon reduction amount. It can be determined by: In other words, the embodiment of this document reduces carbon emissions by preventing the use of the goods by the intermediate entity by storing the goods, extending the life of the goods by the storage period and preventing the use of another third party goods. By looking at it, the third carbon reduction amount can be calculated. For example, as shown in Figure 9, the average lifespan of a specific product is 5 years, the carbon emissions when using the product during its average lifespan (5 years) are 3000 tCO ₂ , and the period for which the relay entity stored the product is 1. If it is determined that it is a year, the third carbon reduction amount saved by use during the storage period of the product can be determined as 1/(5+1)*3000 = 500 tCO2. In this case, as in the example of Figure 9, when calculating the seller's first carbon reduction amount and the buyer's second carbon reduction amount, the first carbon reduction amount is calculated by adding the storage period (1 year) to the original lifespan (5 years) of the product's lifespan. and the second carbon reduction amount can be calculated.

Accordingly, the server 100 may determine the contribution of the subject involved in the used transaction data based on the first carbon reduction amount, the second carbon reduction amount, and the third carbon reduction amount. For example, referring to FIG. 9, the server 100 allows the seller to determine 1st of the total carbon amount of 14000 tCO2 emitted during the production (10000 tCO ₂ ), use (3000 tCO ₂ ), and disposal (1000 tCO ₂ ) process of the product. Calculating that 1 carbon reduction (3000 tCO ₂ ) has been reduced, the seller's contribution can be determined as 3000/14000*100 = 21.4%. The server 100 saves the second carbon reduction amount (10,500 tCO ₂ ) out of the total carbon amount of 14,000 tCO 2 emitted by the buyer during the production (10,000 tCO ₂ ), use (3,000 tCO ₂ ), and disposal (1,000 tCO ₂ ) process of the product. By calculating this, the buyer's contribution can be determined as 10500/14000*100 = 75%. The server 100 allows the relay entity to calculate the third carbon reduction amount (500 tCO ₂ ) out of the total carbon amount of 14,000 tCO 2 emitted during the production (10000 tCO _{2 ), use (3000 tCO 2 )} , and disposal (1000 tCO ₂ ) of the product. Calculating the savings, the contribution of the relay entity can be determined as 500/14000*100 = 3.6%.

In step S2030, the server 100 determines the first carbon reduction amount, the second carbon reduction amount, and the third carbon reduction amount based on the ratio of the first carbon reduction amount, the second carbon reduction amount, and the third carbon reduction amount or the ratio of the first contribution, the second contribution, and the third contribution. A quantity of security tokens corresponding to the value of carbon emissions rights that can be allocated through the sum of the carbon reduction amount and the third carbon reduction amount can be distributed to sellers, buyers, and intermediary entities.

FIG. 12 is an example diagram illustrating an operation in which the server 100 determines the contribution between the seller, buyer, and relay entity based on the transaction price according to the second embodiment. The embodiment of FIG. 12 may include an embodiment of determining the quantity of security tokens to be paid to users (ex. seller, buyer, relay entity, etc.) according to the amount of carbon reduction due to second-hand transactions based on the transaction 'price'. You can.

Referring to FIG. 12, the proof data may include information about used goods transactions. For example, the proof data may include information on the product that has been the subject of a used transaction, information on the subject who performed the used transaction, and information on the used transaction history (e.g. time or price) of the article, and the server 100 It is possible to determine the contribution of entities involved in second-hand transactions and the amount of carbon reduction caused by second-hand transactions. Product information may include information about the type of product, model name, year of production, year of purchase, new price of the product, used price, etc. Information on the entity that performed the used transaction may include seller information, buyer information, and information on the intermediate entity for the used transaction. For example, the intermediary entity for second-hand transactions may include various entities that assist with second-hand transactions, such as companies that provide websites that can perform second-hand transactions, and companies that store second-hand transaction items. Information on the price at which a second-hand transaction of an item has been completed may include price information based on various standards at which a second-hand transaction can be recognized as having been completed, such as information on the second-hand price of the product uploaded by the seller and the price deposited by the buyer.

Referring to FIG. 12, in step S2020, the server 100 calculates the first contribution made by the seller in replacing the disposal of the product and the contribution made by the buyer in replacing the production of the product based on information about the new price and the used transaction price of the product. A second contribution can be determined. For example, the server 100 may set the ratio of the used transaction price to the sum of the new and used transaction prices as the first contribution, and the ratio of the new product price to the total price as the second contribution. . For example, if the price of a new product is 10,000 won and the price of a used product at which a transaction is concluded is 5,000 won, the server 100 determines that the seller has reduced carbon emissions by replacing the disposal of the product and sets the first contribution as 5,000/(10,000+5,000) *Can be set as 100 = 33.3%. Additionally, the server 100 may set the second contribution as 10000/(10000+5000)*100 = 66.7%, considering that the buyer has reduced carbon emissions by replacing the production of the product.

The server 100 may determine the first carbon reduction amount saved by the seller and the second carbon reduction amount saved by the buyer based on the first contribution rate and the second contribution rate. The server 100 may determine the amount of carbon emissions emitted by at least one of the production, use, and disposal processes of the product. For example, the server 100 may calculate the carbon emissions generated during the production of the product based on data defining the carbon emissions by manufacturing weight of the parts constituting the product. For example, the server 100 may calculate the carbon emissions generated when the product is used based on data defining the average lifespan of the product and the amount of carbon emitted when the product is used. For example, the server 100 may calculate the carbon emissions generated when disposing of an article based on data defining the carbon emissions by discarded weight of parts constituting the article. The calculation of carbon emissions generated during the production, use, and disposal of products is explained in conjunction with FIG. 10, so redundant explanations are omitted.

The server 100 may determine the ratio of the first contribution to the determined carbon emissions as the seller's first carbon reduction amount, and determine the ratio of the second contribution to the determined carbon emissions as the buyer's second carbon reduction amount. .

In step S2030, the server 100 creates a security type in a quantity corresponding to the value of carbon credits that can be allocated through the sum of the first carbon reduction amount and the second carbon reduction amount, based on the ratio of the first contribution and the second contribution. Tokens can be distributed to sellers and buyers.

According to another embodiment of FIG. 12, in step S2020, the server 100 applies each subject's contribution based on the 'used' carbon emissions (ex. 3000 tCO ₂ ) emitted by the process of using the product, The amount of carbon reduction saved by each entity can be calculated. For example, assuming the carbon emissions generated during the production, use, and disposal of an article as an example in FIG. 10, the server 100 calculates the carbon emissions generated when disposing of the article to the carbon emissions at the first ratio to the carbon emissions used. The amount added to the carbon emissions (ex. 1000 tCO ₂ ) can be determined as the seller's first carbon reduction amount (=3000*1/3+1000 = 2000 tCO ₂ ). In addition, the amount of carbon emissions generated during the production of the product (10000 tCO ₂ ) added to the carbon emissions of the second contribution (ex. 66.7%) to the carbon emissions used (ex. 3000 tCO ₂ ) is the buyer's second contribution. It can be determined by the amount of carbon reduction (=3000*2/3+10000 = 12000 tCO ₂ ). In other words, each entity's contribution is applied to 'use' carbon emissions, the seller is calculated to have reduced all carbon emissions generated when disposing of the product, and the buyer is calculated to have reduced all carbon emissions generated during production of the product. This is an example.

In step S2030, the server 100 generates a quantity corresponding to the value of carbon credits that can be allocated through the sum of the first carbon reduction amount and the second carbon reduction amount, based on the ratio of the first carbon reduction amount and the second carbon reduction amount. Security tokens can be distributed to sellers and buyers.

In another embodiment of FIG. 12, in step S2020, the server 100 may additionally determine the third contribution contributed by the relay entity providing a service for relaying used transactions to encouraging used transactions as a means of carbon reduction. You can. For example, the relay price may include the relay entity's second-hand transaction service operating costs for the total number of second-hand transactions performed by the relay entity. For example, the relay price may include the cost incurred by the relay entity to repair the product when relaying a used transaction for the product. In FIG. 12, the server 100 is a used transaction price (16,500 won) for the sum of the new product price (10,000 won), the used transaction price (5,000 won), and the relay price (1,500 won) incurred when the relay entity relays the used transaction. The ratio of the transaction price (5,000 won) is set as the first contribution (=30.3%), and the ratio of the new product price (10,000 won) to the total price (16,500 won) is set as the second contribution (=60.7%). The ratio of the relay price (1,500 won) to the total price (16,500 won) can be set as the third contribution (=9%).

The server 100 may additionally determine the third carbon reduction amount saved by the relay entity based on the third contribution contributed by the relay entity. When the carbon emissions determined by the server 100 are 10000 tCO ₂ and the first contribution is 30.3%, the second contribution is 60.7%, and the third contribution is 9%, the server 100 calculates the seller's first carbon reduction amount. * 10000 = 3000 tCO ₂ , the buyer’s second carbon reduction amount * 10000 = 6000 tCO ₂ , the third carbon reduction amount of the relay entity * It can be determined as 10000 = 1000 tCO ₂ .

In step S2030, the server 100 may be allocated through the sum of the first carbon reduction amount, the second carbon reduction amount, and the third carbon reduction amount, based on the ratio of the first carbon reduction amount, the second carbon reduction amount, and the third carbon reduction amount. A quantity of security tokens corresponding to the value of existing carbon emissions rights can be distributed to sellers, buyers, and intermediary entities.

When a security token is paid to the user according to the embodiment of FIGS. 8 to 12 described above, the server 100 may exchange the security token paid to the user for contract company points guaranteed by a predetermined contract company.

Referring again to FIG. 2, the server 100 may pay a portion of the profits generated based on proof data or proof data to the contract company as the contract company guarantees the contract company points. Additionally, if the subject of the server 100 has a debt for a sales receivable, the server 100 may pay a portion of the security token generated through the proof data to the creditor of the sales receivable.

An embodiment of the server 100 for performing this operation may be performed as in operations (a), (b), and (1) to (6) of FIG. 2. The identification codes in (a), (b), and (1) to (6) of FIG. 2 are only symbols and numbers used for convenience of understanding, and the identification codes do not limit the chronological order of the embodiment. In the embodiment of this document, operations may be performed by changing the order of (a), (b), and (1) to (6) of FIG. 2, and (a), (b), and (1) of FIG. 2 Embodiments may be included in which specific steps in (6) are omitted or modified.

In Figure 2 (a), the operator of the server 100 can operate a certain service with investment or support from a creditor 500, and in Figure 2 (b), the operator of the server 100 is a creditor (500). 500), profits due on account receivables can be paid. Additionally, the server 100 may pay the creditor 500 a quantity of security tokens corresponding to the value contracted to be paid to the creditor.

In (1) of FIG. 2, the server 100 may pay a security token to the user terminal 200 according to the above-described embodiment.

In (2) of FIG. 2, the server 100 may obtain the right to use contract company points guaranteed for use/payment by the contract company server 300. For example, the right to use contractor points is data that grants a specific user to a user account the right to use contractor points, or object data that has the ability to use contractor points by a specific user (ex. 'Contractor points', which will be described later) ') may be included.

In (3) of FIG. 2, the server 100 may exchange the security token held by the user for contract company points at a preset rate according to the application of the user terminal 200. For example, the preset ratio may be set so that the value of the contract company points is exchanged at a rate that has a higher value than the market price of carbon emissions rights while the price of the security token is set at the market price of carbon emissions rights.

For example, the server 100 may pay the user a quantity of security tokens proportional to the carbon emissions rights that can be obtained by proof data based on the market price of carbon emissions rights. For example, if the market price of carbon emissions rights is 20,000 won per ton, and it is determined that the user has reduced carbon emissions by 20 kg, the server 100 provides a quantity equivalent to 20 kg x 200 (won/1 kg) = 4,000 won. Security tokens can be paid to the user terminal 200. For example, a security token worth 4,000 won can be deducted through the purchase of a product or use of a service on the server 100 or an affiliated server 100 affiliated with the server 100. The security token is deducted as the user purchases a product or uses a service, and the user's security token can be transferred to the server 100. The server 100 may count the amount corresponding to the security token transferred to the server 100 by the user using the security token as profit.

Security tokens can function as a preliminary claim method that can be exchanged for contract company points, which will be described later, depending on the user's exchange request. The server can exchange the security token paid to the user terminal 200 for contract company points at a preset rate. For example, the ratio is set so that when the price of the security token is set at the market price of carbon emissions rights, the value of the contract company points is exchanged at a rate that is equal to the market price of carbon emissions rights or has a value higher than the market price of carbon emissions rights. can be set. In other words, when the price of 10 security tokens is pegged to the market price of carbon emissions rights and is 10,000 won, 10 tokens can be exchanged for contractor points worth less than 10,000 won. If this is expressed in a formula, it is as shown in Equation 5 below.

[Equation 5]

For example, if the preset rate is that card company points are paid at 80% of the carbon emissions certificate market price, 10 security tokens worth 10,000 won can be exchanged for 8,000 won in card company points. The value of the profit of 2,000 won at this time can be counted as the profit of the server (100). At this time, part of the profits may be paid to other entities (e.g. creditors, contractors) depending on the information in the sales receivables or contract details. For example, the operator of the server 100 may pay the creditor 500 the profit due on the sales receivable. The server 100 may pay proof data or a portion of the revenue based on the proof data to the contract company as the contract company guarantees the use of the contract company points. Additionally, the server 100 may pay a quantity of security tokens corresponding to the value contracted to be paid to the creditor 500 or the contract company server 300.

The server 100 obtains the right to use contract company points from each of the plurality of contract companies, and can exchange the contract company points of the contract company selected by the user among the plurality of contract companies with the user's security token according to the user's request.

For example, assume that multiple contract companies include card company A and card company B. Additionally, it is assumed that the server 100 is set to exchange security tokens and A points of card company A at a rate of 50% of the market price of carbon emissions rights. At this time, if the user requests to exchange his/her security token for A points, the user will receive a security token worth 4,000 won based on the market price of carbon emissions rights. When the user requests to exchange A card company's A point, the user will receive a security token worth 4,000 won. Token is It can be exchanged for Won A points.

For example, assume that the server 100 is set to exchange security tokens and B points of card company B at a rate of 70% of the market price of carbon emissions rights. At this time, if the user requests to exchange his or her security token for B points, the security token equivalent to 4,000 won based on the market price of carbon emissions rights. When the user requests to exchange the B point of card company B, the security token worth 4,000 won is exchanged. Token is It can be exchanged for Won B points.

In (4) of FIG. 2, the user terminal 200 can use the paid contractor points at the affiliated store 350.

In (5) of FIG. 2, the contract company server 300 can guarantee the use of contract company points at the affiliated store 350. For example, the contract company server 300 may transfer cash corresponding to the contract company points used by the user at the affiliated store 350 to the affiliated store 350 account.

In (6) of FIG. 2, the server 100 may pay proof data or a portion of the revenue based on the proof data to the contract company as the contract company guarantees the use of the contract company points. Additionally, the server 100 may pay the contractor a quantity of security tokens corresponding to the value contracted to be paid to the contractor.

As an example, the server 100 may distribute profits generated based on the acquired proof data or carbon emission credits to users holding security tokens. The server 100 may distribute profits in proportion to the amount of security tokens held by the user.

According to the above-described embodiment, a security token that specifies carbon emissions rights is issued so that the rights or value of carbon emissions rights can be distributed to individuals, and the amount of carbon reduction is objectively determined through proof data on carbon reduction events performed by users. By calculating it, it is possible to present fair compensation for individual efforts to reduce carbon emissions. In addition, blockchain technology can be used to issue and trade carbon credits as security tokens, thereby promoting liquidity and revitalization of the carbon emissions market.

Accordingly, users can check the amount of carbon they have saved and the corresponding compensation in real time, and entities using the technology of the present invention can provide incentives for carbon reduction and contribute to environmental protection.

Through this, the embodiments of this document enable the active operation of an incentive system for reducing carbon emissions that actively responds to government policies and the needs of the times, and also actively provide investment and support to encourage efforts to reduce carbon emissions. A desirable environment can be created.
