Description

Profit sharing device, program and recording medium

[0001] The present disclosure relates to a profit sharing device, a program, and a recording medium.The present disclosure particularly relates to a profit sharing device, a program, and a recording medium for sharing profits from carbon credit trading.

[0002] In recent years, carbon neutrality, which aims to balance greenhouse gas emissions and absorption, has been advocated as an approach to combat global warming. To achieve carbon neutrality, carbon credit trading mechanisms are beginning to be established, which enable greenhouse gas emission reductions to be bought and sold between entities (countries, regions, organizations, corporations, individuals, etc.).

[0003] For example, Patent Literature 1 discloses a system for supporting the trading of carbon dioxide emission rights, which is composed of multiple trading terminals and a trading site. Patent Literature 2, for example, describes a system in which a carbon credit issuer trades with a purchaser of a carbon credit product through a carbon credit intermediary or the like (see FIG. 3A). For example, a system is known in which a supplier of a carbon credit product trades with a carbon credit purchaser through a carbon credit issuer (see FIG. 3B). For example, a system is known in which a purchaser of a carbon credit product trades with a carbon credit issuer (see FIG. 3C). For example, a system is known in which a supplier of a carbon credit product trades with a carbon credit issuer through a carbon credit intermediary (see FIG. 3D).

[0005] Here, in order to conduct carbon credit trading, a sales record of carbon credit eligible products is required. In the trading system shown in Figures 3A to 3D, the supplier of carbon credit eligible products must sell the carbon credit eligible products. In many cases, suppliers of carbon credit eligible products supply carbon credit eligible products but do not sell them. Therefore, the trading system shown in Figures 3A to 3D does not match the system of normal commercial transactions, for example, via a retailer. Furthermore, since the system is designed to give profits only to the supplier of carbon credit eligible products or only to the purchaser of carbon credit eligible products, it does not take into account the distribution of profits when transactions are made via a retailer, etc.

[0006] In view of the above circumstances, an object of the present disclosure is to provide a profit distribution device, a program, and a recording medium that can revitalize carbon credit trading.

[0007] (1) A profit distribution device according to one embodiment of the present disclosure is a profit distribution device that distributes profits obtained through carbon credit trading of carbon credit eligible products to suppliers, intermediaries, and purchasers of the carbon credit eligible products via information terminals, and includes: a memory unit that stores supply information and sales information of the carbon credit eligible products and stores the profits; and a calculation unit that calculates the contribution rates of the supplier, intermediary, and purchaser to the profits based on the supply information and the sales information, and distributes the profits to the supplier, intermediary, and purchaser according to the contribution rates.

[0010] (4) As an embodiment of the present disclosure, in any one of (1) to (3), the number of suppliers and the number of purchasers are each one or more, and the number of intermediaries is zero or more.

[0011] (5) As an embodiment of the present disclosure, in any one of (1) to (4), the profits obtained through the carbon credit trading of the carbon credit eligible product are profits obtained via a carbon credit intermediary.

[0012] (6) As an embodiment of the present disclosure, in any of (1) to (5), the calculation unit distributes the profit to the supplier, the intermediary, and the purchaser through collaborators who are not directly involved in the transaction of the carbon credit eligible product.

[0017] Hereinafter, a profit distribution device 10 (see FIG. 1) and a program according to an embodiment of the present disclosure will be described with reference to the drawings.

[0018] FIG. 1 is a diagram illustrating an example of the configuration of a profit distribution system 1 including a profit distribution device 10 according to this embodiment. FIG. 2A is a diagram illustrating a carbon credit trading mechanism executed by the profit distribution system 1 of FIG. 1. The profit distribution device 10 distributes profits obtained through carbon credit trading of carbon credit eligible products to suppliers, intermediaries, and purchasers of the carbon credit eligible products via an information terminal 70. Hereinafter, suppliers of carbon credit eligible products will be referred to simply as "suppliers." Intermediaries of carbon credit eligible products will be referred to simply as "intermediaries." Purchasers of carbon credit eligible products will be referred to simply as "purchasers." Carbon credit eligible products are goods or services that contribute to achieving carbon neutrality, such as products that reduce greenhouse gas emissions during the manufacturing process. Specific examples of carbon credit products include afforestation, reforestation, soil carbon sequestration, biochar, land-based biomass storage, and bioenergy with carbon capture and storage (BECCS). Carbon credit products can also include direct air carbon capture and storage (DACCS). Carbon credit products can also include carbonated materials, accelerated weathering, blue carbon, ocean alkalinization, energy conservation, renewable energy, industrial processes, agriculture, waste, automobiles, and housing. As shown in FIG. 2A , when a carbon credit product is registered (certified) by a carbon credit issuer and carbon credits are sold, "profits earned from carbon credit transactions of carbon credit products" are generated. The profits may be monetary (amount of money) or a monetary value that can be exchanged for money or used to purchase goods, like money. Carbon credits function as permits for greenhouse gas emissions. In other words, carbon credit purchasers can emit greenhouse gases equivalent to the amount of carbon credits they purchase. In drawings, etc., carbon credit purchasers and intermediaries are referred to as "carbon credit purchasers" and "carbon credit intermediaries," respectively, to distinguish them from purchasers and intermediaries of carbon credit-eligible products.

[0019] Here, registration of carbon credit eligible products may be performed not only by carbon credit issuers but also by carbon credit intermediaries. Figure 2B is a diagram illustrating a carbon credit trading mechanism executed by the profit sharing system 1 of Figure 1. As shown in Figure 2B, carbon credit eligible products may be registered (certified) by a carbon credit intermediary, and carbon credits may be sold via the carbon credit issuer. In this carbon credit trading mechanism, profits earned through carbon credit trading of carbon credit eligible products are profits earned via the carbon credit intermediary.

[0020] As shown in FIG. 1, the profit distribution device 10 comprises a communication unit 11, a memory unit 12, and a calculation unit 13. The profit distribution device 10 may have a hardware configuration such as a computer. Details of the components of the profit distribution device 10 will be described later. The profit distribution device 10 may not be a single device, but may be composed of multiple devices located in multiple locations and capable of sending and receiving data between them via a network 40. For example, the profit distribution device 10 may have a hardware configuration such as a single computer, or multiple computers connected via a network 40. When composed of multiple computers, the memory unit 12 may be a shared memory accessible by each computer.

[0021] The profit distribution device 10 may constitute a profit distribution system 1 together with an information terminal 70 connected via a network 40. The network 40 is, for example, the Internet. The network 40 may also be configured to include, for example, a local area network (LAN) in part. In this embodiment, the profit distribution system 1 can access a device that manages carbon credit transactions of a carbon credit issuer via the network 40. The profit distribution device 10 acquires "profits earned through carbon credit transactions of carbon credit eligible products" via the network 40. Here, the profit distribution system 1 may be configured to further include a device that manages carbon credit transactions.

[0022] The information terminal 70 is, for example, a computer separate from the profit distribution device 10. In this embodiment, the information terminal 70 is used by each of the supplier, intermediary, and purchaser in the transaction (sale) of the carbon credit eligible product. As shown in FIG. 1 , when distinguishing between the information terminals 70 of the supplier, intermediary, and purchaser, they may be referred to as information terminal 70s, information terminal 70m, and information terminal 70u. The information terminal 70 may be, for example, a general-purpose mobile terminal such as a smartphone or tablet. The information terminal 70 may have a display (display unit) so that the supplier, intermediary, and purchaser can check the distributed profits. The information terminal 70 may also have functions similar to those of the communication unit 11, memory unit 12, and calculation unit 13 of the profit distribution device 10, i.e., communication function, memory function, and calculation function. The information terminal 70 may have an input unit through which the supplier, intermediary, and purchaser can input data. In this case, the information terminal 70 may have a touch panel display in which the input unit and display unit are integrated.

[0023] As shown in Figure 2A or 2B, a supplier sells a carbon credit product to an intermediary. The supplier is, for example, a manufacturer of the carbon credit product. The intermediary is, for example, a processor or seller of the carbon credit product. A specific example of a seller is a retailer. The intermediary sells the carbon credit product to a buyer. The buyer is, for example, a user of the carbon credit product or a processed product thereof. Here, there are one or more suppliers and buyers (one or more entities). There can be multiple suppliers and buyers. Also, there can be zero or more intermediaries (zero or one or more entities). There can be no intermediary, or there can be multiple intermediaries.

[0024] The components of the profit distribution device 10 will be described in detail below. The communication unit 11 includes one or more communication modules connected to the network 40. The communication unit 11 may include a communication module compatible with mobile communication standards such as 4G (4th Generation) and 5G (5th Generation). The communication unit 11 may also include a communication module compatible with a wireless or wired LAN standard.

[0025] The storage unit 12 is one or more memories. The memory may be, for example, a semiconductor memory, a magnetic memory, an optical memory, or the like, but is not limited to these, and may be any memory. The storage unit 12 is, for example, built into the profit distribution device 10, but may also be configured to be externally accessed by the profit distribution device 10 via any interface.

[0026] The storage unit 12 stores various data used in various calculations performed by the calculation unit 13. The storage unit 12 may also store results and intermediate data of various calculations performed by the calculation unit 13.

[0027] In this embodiment, the storage unit 12 stores supply information and sales information of the carbon credit eligible product acquired via the communication unit 11. The storage unit 12 also stores profits (P ｃａｒｂｏｎｃｒｅｄｉｔ ) Furthermore, when processing information of the carbon credit eligible product is acquired via the communication unit 11, the storage unit 12 further stores the processing information.

[0028] Supply information is obtained from the supplier's information terminal 70s, and the raw material cost (c ｍａｔｅｒｉａｌ ) Sales information includes raw material profit (P ｍａｔｅｒｉａｌ ) and product profit (P ｐｒｏｄｕｃｔ ) The raw material profit is obtained from the information terminal 70s of the supplier or the information terminal 70m of the intermediary. The product profit is obtained from the information terminal 70m of the intermediary or the information terminal 70u of the purchaser. The processing information is obtained from the information terminal 70m of the intermediary, and the manufacturing cost (c ｐｒｏｄｕｃｔ ) Processing information is acquired when the intermediary is a processor. For example, if the intermediary is a seller who does not process the carbon credit eligible product, processing information is not acquired.

[0029] In this embodiment, the storage unit 12 stores a lower limit of profit (set lower limit profit) set by the supplier, the intermediary, and the purchaser before the distribution of profits obtained through the carbon credit trading of the carbon credit target product. ｓｕｐｐｌｉｅｒ) is input in advance by the supplier into the information terminal 70s and can be obtained from the information terminal 70s. ｍａｋｅｒ ) is input in advance by the intermediary into the information terminal 70m and can be obtained from the information terminal 70m. ｕｓｅｒ ) is input in advance by the purchaser into the information terminal 70u and can be obtained from the information terminal 70u. The set minimum profit limit may be set as a positive value, or as zero or a negative value when no profit is required. For example, suppliers and intermediaries may set a positive value taking only sales profit into consideration. For example, suppliers may set a negative value taking into consideration disposal fees in the event that a carbon credit eligible product cannot be sold. Furthermore, while the set minimum profit limit of a purchaser is generally a negative value, for example, an environmentally conscious purchaser, i.e., a purchaser who is more interested in contributing to achieving carbon neutrality than profit, may set a negative value taking into consideration the price difference with products not eligible for carbon credits.

[0030] The calculation unit 13 may be configured to include one or more processors. The processor may be, for example, a general-purpose processor or a dedicated processor specialized for a specific process, but is not limited to these and may be any processor. The calculation unit 13 may have a function as a control unit that controls the overall operation of the profit distribution device 10. For example, the calculation unit 13 may obtain the above-mentioned supply information, sales information, processing information, etc. from the information terminal 70 and store them in the memory unit 12.

[0031] The calculation unit 13 calculates the contribution rate of each of the supplier, intermediary, and purchaser to the profit based on the supply information, sales information, and processing information. In this embodiment, the calculation unit 13 calculates the contribution rate of the supplier, r ｓｕｐｐｌｉｅｒ , the contribution rate of the intermediary, r ｍａｋｅｒ and the purchaser's contribution rate r ｕｓｅｒ Calculate.

[0032]

[0033] Here, P ｓｕｐｐｌｉｅｒ is the supplier's profit. ｍａｋｅｒ is the profit of the intermediary. ｕｓｅｒis the buyer's profit. The last equation shows that the sum of the supplier's contribution rate, the intermediary's contribution rate, and the buyer's contribution rate is 1. Also, as mentioned above, the profit obtained from carbon credit trading is P ｃａｒｂｏｎｃｒｅｄｉｔ , raw material profit is P ｍａｔｅｒｉａｌ , product profit is P ｐｒｏｄｕｃｔ The raw material cost is c ｍａｔｅｒｉａｌ , manufacturing cost is c ｐｒｏｄｕｃｔ In addition, the supplier's minimum profit is L ｓｕｐｐｌｉｅｒ , the intermediary's set lower limit profit is L ｍａｋｅｒ , the buyer's set lower limit profit is L ｕｓｅｒ The calculation unit 13 calculates the contribution rates of the supplier, intermediary, and purchaser so that all equations are satisfied, thereby appropriately determining the contribution rates while satisfying the respective minimum profit limits for the supplier, intermediary, and purchaser. The contribution rates can be set to values ​​that do not satisfy the minimum profit limits in calculations. However, since ensuring economic rationality in transactions is a common approach, it is preferable to set the contribution rates so as to satisfy the respective minimum profit limits for the supplier, intermediary, and purchaser. Furthermore, profits are also distributed to intermediaries (processors or sellers of carbon credit-eligible products), which were not considered in conventional technology, according to their contribution rates. By distributing profits to all entities involved in the sale of carbon credit-eligible products in this way, it is possible to increase the willingness of all entities to engage in carbon credit trading, thereby revitalizing carbon credit trading.

[0034] As mentioned above, the intermediary may be a seller who does not perform processing. In this case, processing information may not be obtained. In addition, the manufacturing cost (c ｐｒｏｄｕｃｔ ) may be set to zero. That is, the calculation unit 13 calculates the contribution rate of each of the supplier, intermediary, and purchaser to the profit based on at least the supply information and sales information, and distributes the profit to the supplier, intermediary, and purchaser according to the contribution rate. The calculation unit 13 may output the contribution rate of each of the supplier, intermediary, and purchaser or the distributed profit obtained by multiplying the profit by the contribution rate to each information terminal 70.

[0035] Here, suppliers, intermediaries, and purchasers may be able to sell carbon credit-eligible products with the cooperation of collaborators who are not directly involved in the transaction. A collaborator may be, for example, a trading company or an agent, who mediates sales by contract and is not a processor or seller (i.e., does not directly process or sell). In this type of sales format, the calculation unit 13 may distribute profits to suppliers, intermediaries, and purchasers through collaborators who are not directly involved in the transaction of carbon credit-eligible products. In other words, the manner in which the calculation unit 13 distributes profits to suppliers, intermediaries, and purchasers includes not only the above-mentioned manner in which the calculation unit 13 distributes profits directly, but also a manner in which the calculation unit 13 distributes profits to suppliers, intermediaries, and purchasers via collaborators. Figures 2C and 2D show a carbon credit trading system in which profits are distributed to suppliers, intermediaries, and purchasers via collaborators. For example, the calculation unit 13 may calculate a contribution rate so that profits are distributed from the supplier to the intermediaries and purchasers via collaborators, and distribute profits according to the contribution rate. For example, the calculation unit 13 may calculate a contribution rate so that profits are distributed from the intermediary to the supplier and the purchaser via the collaborator, and distribute the profits according to the contribution rate. For example, the calculation unit 13 may calculate a contribution rate so that profits are distributed from the purchaser to the supplier and intermediary via the collaborator, and distribute the profits according to the contribution rate. For example, the calculation unit 13 may calculate a contribution rate so that profits are distributed from the supplier and intermediary to the purchaser via the collaborator, and distribute the profits according to the contribution rate. Here, when profits are distributed via the collaborator, a portion of the profits may also be distributed to the collaborator as a fee.

[0036] Here, the profit distribution device 10 may have the following software configuration: One or more programs used to control the operation of the profit distribution device 10 are stored in the storage unit 12 or another storage medium readable by the profit distribution device 10. When the programs stored in the storage unit 12 or another storage medium are read by the processor of the calculation unit 13, the processor may function to execute the profit distribution process described above. That is, the programs may cause the profit distribution device 10 to store supply information and sales information for carbon credit eligible products and to store profits. The programs may then cause the profit distribution device 10 to calculate the contribution rates of the supplier, intermediary, and purchaser to the profits based on the supply information and sales information, and distribute the profits to the supplier, intermediary, and purchaser according to the contribution rates.

[0037] As described above, the profit distribution device 10 and the program according to this embodiment can activate carbon credit trading with the above-described configuration.

[0038] Although the embodiments of the present disclosure have been described based on the drawings and examples, it should be noted that those skilled in the art would easily be able to make various modifications or alterations based on the present disclosure. Therefore, it should be noted that these modifications and alterations are included within the scope of the present disclosure. For example, the functions included in each component or step can be rearranged so as not to cause logical inconsistencies, and multiple components or steps can be combined or divided into one. The embodiments of the present disclosure can also be realized as a storage medium (non-transitory computer-readable storage medium) on which a program executed by a processor included in an apparatus is recorded. It should be understood that these are also included within the scope of the present disclosure.

[0039] In the above embodiment, the profit distribution device 10 is described as being realized by a computer or the like different from the information terminal 70, but the profit distribution device 10 may be realized by one of the information terminals 70. In other words, the above processing performed by the communication unit 11, memory unit 12, and calculation unit 13 of the profit distribution device 10 may be realized by the communication function, memory function, and calculation function of the information terminal 70. As an example, the supplier's information terminal 70s may execute the profit distribution processing. As an example, the intermediary's information terminal 70m may execute the profit distribution processing. Also, as an example, the purchaser's information terminal 70u may execute the profit distribution processing. In this case, the profit distribution system 1 may be composed of only multiple information terminals 70.

[0040] In the above embodiment, the calculation unit 13 of the profit distribution device 10 executes all calculations of profit distribution, but the calculation may be shared with the information terminal 70. For example, the calculation unit 13 may calculate the profit of the supplier (P ｓｕｐｐｌｉｅｒ ), intermediary profits (P ｍａｋｅｒ ) and the purchaser's profits (P ｕｓｅｒ ) and output them to the information terminal 70s, the information terminal 70m, and the information terminal 70u. Then, each of the information terminals 70s, 70m, and 70u may calculate the set lower limit profit (L ｓｕｐｐｌｉｅｒ ), the intermediary's set minimum profit (L ｍａｋｅｒ ), the buyer's set minimum profit (L ｕｓｅｒ ) and output the comparison result to the profit distribution device 10. In this case, the processing load of the profit distribution device 10 can be reduced.

[0041] The calculation unit 13 may also calculate the profit distribution, store the calculation results in the storage unit 12, and display the profit distribution history (such as changes over time) on the information terminal 70 via the communication unit 11 and the network 40 based on the stored information. The calculation unit 13 may also display not only the profit distribution history but also the amount of carbon dioxide tons (t-CO ２) and output it as a calculation result together with the profit sharing history. FIG. 4 shows an example of a screen of the calculation results that the calculation unit 13 displays on the information terminal 70. In the example of FIG. 4, the profit sharing history and sales history are shown in chronological order. Also, a year-by-year comparison (YoY) is shown. By displaying such a display on the information terminal 70, suppliers, intermediaries, and purchasers of carbon credit eligible products are reminded of their contribution to carbon neutrality, which can further stimulate carbon credit trading.
