Description

[Technical Field]

[0001] An embodiment of the present invention relates to a greenhouse gas transfer support system, a greenhouse gas transfer support method, and a program. [Background technology]

[0002] Countermeasures against global warming are a global issue, and in order to reduce greenhouse gases, the application of technologies such as carbon dioxide capture and storage is being promoted. With this technology, carbon dioxide is separated and captured from exhaust gases emitted by facilities that emit large amounts of carbon dioxide, such as thermal power plants, before being released into the atmosphere, and then injected into stable geological formations deep underground for long-term storage.

[0003] Furthermore, the application of technology to effectively utilize captured carbon dioxide is also progressing. For example, this technology involves injecting carbon dioxide into old oil fields, which pressurizes the remaining crude oil and stores the carbon dioxide underground, leading to increased oil production.

[0004] Furthermore, efforts are underway to use carbon dioxide as a resource to produce valuable products such as chemicals and fuels. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 8-127544 Summary of the Invention [Problem to be solved by the invention]

[0006] As mentioned above, reductions in greenhouse gas emissions such as carbon dioxide are being recommended, and an increasing number of companies and organizations are seeking to reduce their greenhouse gas emissions.

[0007] However, even if greenhouse gases are captured at great expense, they cannot be handed over unless a company or organization is partnered with to receive, store, or effectively utilize the captured greenhouse gases. If there are few companies or organizations that store or effectively utilize greenhouse gases, progress in greenhouse gas reduction will be slow.

[0008] The problem to be solved by the present invention is to provide a greenhouse gas transfer support system, a greenhouse gas transfer support method, and a program that can promote the reduction of greenhouse gas emissions. [Means for solving the problem]

[0009] A greenhouse gas transfer support system according to one embodiment includes a first communication terminal used by a first trader that transfers greenhouse gas, a second communication terminal used by a second trader that receives greenhouse gas, and a server device connected to the first and second communication terminals via a network. The server device includes a memory unit that stores the greenhouse gas transfer conditions of the first trader received from the first communication terminal and the greenhouse gas receiving conditions of the second trader received from the second communication terminal, and a discrimination unit that determines the degree of conformity between the transfer conditions and the receiving conditions. The first communication terminal includes a first input unit that accepts input of the transfer conditions, a first output unit that displays the discrimination result received from the server device, and a first communication unit that notifies the second communication terminal used by the second trader of the result of the first trader's selection of a second trader with whom the first trader wishes to trade based on the discrimination result. The second communication terminal has a second input unit that accepts input operations for receiving conditions, a second output unit that displays the determination results received from the server device, and a second communication unit that notifies the first communication terminal used by the first trader who wishes to trade of the result of the second trader selecting the first trader with whom he or she wishes to trade based on the determination results. [Effects of the Invention]

[0010] According to this embodiment, it is possible to promote reduction of carbon dioxide emissions. [Brief explanation of the drawings]

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The present invention is not limited to the following embodiments.

[0013] (First embodiment) FIG. 1 is a schematic diagram for explaining a greenhouse gas transfer support service using a greenhouse gas transfer support system.

[0014] The greenhouse gas transfer support system 1 shown in Figure 1 brings together a first trader 100 who transfers greenhouse gases and a second trader 200 who receives greenhouse gases. The greenhouse gas transfer support system 1 is, for example, a computer system connected to a website, and can be used by anyone with a personal computer or smartphone connected to the Internet. Greenhouse gases include, for example, carbon dioxide, chlorofluorocarbons, methane, and nitrous oxide.

[0015] In FIG. 1, at least one first transactor 100 is registered in the greenhouse gas transfer support system 1 as a greenhouse gas transferor. At least one second transactor 200 is also registered in the greenhouse gas transfer support system 1 as a greenhouse gas receiver. The second transactor 200 is a company that effectively utilizes greenhouse gases, for example, a company that produces valuable materials using carbon dioxide as a raw material. The first transactor 100 and the second transactor 200 may be individuals, groups, or organizations. The first transactor 100 and the second transactor 200 may be singular or plural.

[0016] The first transactor 100 can select a trading partner from among the second transactors 200 registered in the greenhouse gas transfer support system 1. Meanwhile, the second transactor 200 can also select a trading partner from among the first transactors 100 registered in the greenhouse gas transfer support system 1. When the first transactor 100 and the second transactor 200 are in a mutually selected relationship, they conduct transaction negotiations. Transaction negotiations include, for example, negotiations on the transaction volume, transaction period, forward delivery terms, etc. After the transaction is concluded, the transfer of greenhouse gases, such as carbon dioxide, is realized. In FIG. 1, greenhouse gases 300 are transferred from the first transactor 100 to the second transactor 200, and a first remuneration 400 is transferred from the second transactor 200 to the first transactor 100. This first remuneration 400 is, for example, money.

[0017] FIG. 2 is a schematic diagram for explaining another greenhouse gas transfer support service using the greenhouse gas transfer support system.

[0018] In FIG. 2, the second transactor 200 is a company or organization that effectively utilizes or stores greenhouse gases. For example, the first transactor 100 wants to ensure that the carbon dioxide is collected in order to reduce carbon dioxide emissions. However, there are often few second transactors 200 that can accept the carbon dioxide due to transportation difficulties and other reasons. In this case, the carbon dioxide collection process is slow to progress. Therefore, the first transactor 100 wants the second transactor 200 to accept the carbon dioxide even if it means paying money. In this case, if the first transactor 100 and the second transactor 200 are mutually selected in the greenhouse gas transfer support system 1, the two parties negotiate a transaction. When the transaction is concluded, the first transactor 100 transfers the greenhouse gas 300 and the second remuneration 500 to the second transactor 200, while the second transactor 200 transfers nothing to the first transactor 100.

[0019] 3 is a block diagram showing the configuration of a greenhouse gas transfer support system 1 according to the first embodiment. The greenhouse gas transfer support system 1 according to this embodiment includes a first communication terminal 10, a second communication terminal 20, and a server device 30. The first communication terminal 10 and the second communication terminal 20 are connected to the server device 30 via a network 40. The first communication terminal 10, the second communication terminal 20, and the server device 30 may be connected to the network 40 by wire or wirelessly.

[0020] The first communication terminal 10 is used by the first trader 100 and is realized by, for example, a personal computer, a smartphone, etc. The first communication terminal 10 has an input unit 11 (first input unit), a communication unit 12 (first communication unit), and an output unit 13 (first output unit).

[0021] The input unit 11 functions as an input interface that accepts input operations by the first transactor 100. The input unit 11 is configured with, for example, a keyboard, a mouse, a touch panel, and the like.

[0022] The communication unit 12 communicates with the server device 30 via the network 40. In communication with the server device 30, the communication unit 12 transmits input data received by operation of the input unit 11 to the server device 30. The communication unit 12 also receives various data from the server device 30.

[0023] The output unit 13 is a display device that displays various data such as data required for input operations and data received by the communication unit 12. The output unit 13 is configured, for example, by a liquid crystal display.

[0024] The second communication terminal 20 is used by the second trader 200 and is realized by, for example, a personal computer or a smartphone. The second communication terminal 20 has an input unit 21 (second input unit), a communication unit 22 (second communication unit), and an output unit 23 (second output unit). Each unit of the second communication terminal 20 is similar to the input unit 11, communication unit 12, and output unit 13 of the first communication terminal 10 described above, and therefore description thereof will be omitted.

[0025] 3 indicate that in the greenhouse gas transfer support system 1, a plurality of first communication terminals 10 and a plurality of second communication terminals 20 are each connected to the server device 30 via the network 40. However, in the greenhouse gas transfer support system 1, the number of first communication terminals 10 and second communication terminals 20 is not particularly limited, and may be one.

[0026] The server device 30 includes a communication unit 31 (third communication unit), a determination unit 32, and a storage unit 33. The communication unit 31 communicates with the first communication terminal 10 and the second communication terminal 20 via the network 40.

[0027] The determination unit 32 performs various determination operations based on data stored in the storage unit 33. The determination unit 32 is configured, for example, with a CPU (Central Processing Unit) that performs arithmetic processing based on a predetermined program (software).

[0028] The storage unit 33 stores data regarding greenhouse gases, including the delivery conditions of each first transactor 100 and the receiving conditions of each second transactor 200. The storage unit 33 is configured, for example, by a hard disk or semiconductor memory.

[0029] The operation of the greenhouse gas transfer support system 1 will be described below with reference to Fig. 4. Fig. 4 is a sequence diagram showing an example of an operation sequence of the greenhouse gas transfer support system 1 according to the first embodiment. The sequence processing described below can be realized, for example, by the first communication terminal 10, the second communication terminal 20, and the server device 30 executing a predetermined program.

[0030] In the sequence diagram shown in Fig. 4, first, a plurality of first traders 100 operate the input unit 11 of their own first communication terminal 10 to input the greenhouse gas delivery conditions (step S101). The greenhouse gas delivery conditions include, for example, the type of greenhouse gas to be delivered, the delivery period, and the delivery amount. The first input data indicating the greenhouse gas delivery conditions input through the input unit 11 of each first communication terminal 10 is transmitted from the communication unit 12 to the server device 30 via the network 40 together with a delivery number for identifying each first trader 100.

[0031] In parallel with step S101, multiple second traders 200 operate the input units 21 of their own second communication terminals 20 to input greenhouse gas receiving conditions (step S102). The greenhouse gas receiving conditions include, for example, the type of greenhouse gas to be received, the receiving period, and the amount to be received. The second input data indicating the greenhouse gas receiving conditions input through the input unit 21 of each second communication terminal 20 is transmitted from the communication unit 22 to the server device 30 via the network 40 together with a receiving number for identifying each second trader 200.

[0032] In the server device 30, the communication unit 31 receives the first input data and the second input data (step S103). The data received by the communication unit 31 is stored in the storage unit 33 (step S104).

[0033] Fig. 5 is a diagram showing an example of a database stored in the storage unit 33 according to the first embodiment. As shown in Fig. 5, the database 330 is made up of a first database 331 and a second database 332. The first database 331 shows the greenhouse gas delivery conditions input to each first communication terminal 10 in step S101 in association with the delivery number. On the other hand, the second database 332 shows the greenhouse gas receipt conditions input to each second communication terminal 20 in step S101 in association with the receipt number. Note that the structure of the database 330 is not limited to the example shown in Fig. 5.

[0034] Once the database 330 is created in the storage unit 33, the discrimination unit 32 then determines the degree of conformance of the delivery conditions and the receipt conditions, or the condition conformance indicating whether the conditions are met, for each of the multiple first transactors 100 and the multiple second transactors 200 based on this database 330 (step S105). Here, an example of a method for determining the degree of conformance of the conditions by the discrimination unit 32 will be described.

[0035] For example, the discrimination unit 32 compares the types of greenhouse gases indicated in the delivery conditions of multiple first traders 100 identified by delivery numbers with the types of greenhouse gases indicated in the receipt conditions of multiple second traders 200 identified by receipt numbers. As a result, if the types of delivery conditions and the types of receipt conditions match, the discrimination unit 32 determines that the degree of condition conformance is 100%, and if they do not match, determines that the degree of condition conformance is 0%.

[0036] The discrimination unit 32 also calculates the difference between the greenhouse gas delivery period and delivery amount indicated in the delivery conditions of each first transactor 100 and the receipt period and receipt amount indicated in the receipt conditions of each second transactor 200. Next, the discrimination unit 32 calculates the condition conformance level according to the difference between the delivery conditions and the receipt conditions. At this time, the condition conformance level is preset according to the difference. For example, if the delivery period is one year and the matching period in the receipt period is six months, the condition conformance level is 50% (= (6 / 12) × 100). Furthermore, if the delivery amount is 100 t and the receipt amount is 200 t, the condition conformance level is 200% (= (200 / 100) × 100).

[0037] When the discrimination unit 32 discriminates the degree of conformance to the above conditions for the combinations of all first traders 100 and all second traders 200, the communication unit 31 transmits the discrimination results to the first communication terminal 10 and the second communication terminal 20 via the network 40 (step S106). At this time, the communication unit 31 transmits the discrimination results for each first trader 100 identified by the delivery number and each second trader 200 identified by the receipt number.

[0038] In the first communication terminal 10, the discrimination result is received by the communication unit 12 and displayed by the output unit 13 (step S107). Meanwhile, in the second communication terminal 20, the discrimination result is received by the communication unit 22 and displayed by the output unit 23 (step S108).

[0039] Fig. 6 is a diagram showing an example of the determination result displayed on the first communication terminal 10. The image 130 shown in Fig. 6 is the determination result displayed on the first communication terminal 10 of the first transactor 100 identified by the delivery number 100a. Therefore, this image 130 displays the conformity of the receiving conditions of each second transactor 200 with the delivery conditions of this first transactor 100.

[0040] Figure 7 is a diagram showing an example of the determination result displayed on the second communication terminal 20. The image 230 shown in Figure 7 is the determination result displayed on the second communication terminal 20 of the second transactor 200 identified by the receipt number 200a. Therefore, this image 230 displays the conformity of the delivery conditions of each first transactor 100 with the receipt conditions of this second transactor 200.

[0041] When the judgment results of the degree of suitability of conditions are displayed on each first communication terminal 10 and each second communication terminal 20 as described above, each first trader 100 refers to the judgment results displayed on the output unit 13 and selects a second trader 200 with whom they wish to trade, and inputs the selection into the input unit 11 (step S109). In parallel with step S109, each second trader 200 refers to the judgment results displayed on the output unit 23 and selects a first trader 100 with whom they wish to trade, and inputs the selection into the input unit 21 (step S110).

[0042] When the input unit 11 receives the selection input of the second transactor 200, the communication unit 12 notifies the selection result to the second communication terminal 20 of the second transactor 200 (step S111). This notification is displayed on the output unit 23 of the second communication terminal.

[0043] On the other hand, when the input unit 21 receives the selection input of the first transactor 100, the communication unit 22 notifies the first communication terminal 10 of the selection result (step S112). This notification is displayed on the output unit 13 of the first communication terminal 10.

[0044] Thereafter, if the first transactor 100 inputs the second transactor 200 as a person willing to transact, the second transactor 200 will determine whether or not to transact with the first transactor 100. As a result, if an agreement is reached, the first transactor 100 will transact with the second transactor 200. Also, if the second transactor 200 inputs the first transactor 100 as a person willing to transact, the first transactor 100 will determine whether or not to transact with the second transactor 200, and if an agreement is reached, the second transactor 200 will transact with the first transactor 100. In this way, the transfer of greenhouse gases is realized.

[0045] According to the present embodiment described above, it is possible to promote transactions by matching companies or organizations that wish to transfer greenhouse gases with companies or organizations that wish to receive greenhouse gases via the greenhouse gas transfer support system 1. This makes it possible to promote the reduction of greenhouse gas emissions.

[0046] (Second embodiment) In the first embodiment described above, for example, if the second trader 200 is a company that injects carbon dioxide into old oil fields to pressurize the remaining crude oil in the oil fields, it is desirable that the carbon dioxide to be received be of sufficiently high pressure. Also, if the second trader 200 is a company that produces valuable products using carbon dioxide as a raw material, it may not want to receive the recovered carbon dioxide depending on its purity, particularly the type and amount of impurities other than carbon dioxide.

[0047] Therefore, in the second embodiment, a greenhouse gas property condition is added to the delivery conditions of the first trader 100. The greenhouse gas property condition includes, for example, the pressure and temperature of the greenhouse gas, and the type and amount of impurities contained in the greenhouse gas.

[0048] The configuration of the greenhouse gas transfer support system used in this embodiment is similar to that of the greenhouse gas transfer support system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the greenhouse gas transfer support system according to this embodiment will be described, focusing on the differences from the first embodiment.

[0049] In this embodiment, in step S101 shown in Figure 4, when multiple first traders 100 operate the input unit 11 of their own first communication terminal 10 to input the greenhouse gas transfer conditions, they also input the greenhouse gas property conditions.

[0050] The input greenhouse gas property conditions are received by the communication unit 31 of the server device 30 together with other transfer conditions in step S103 and stored in the storage unit 33.

[0051] Fig. 8 is a diagram showing an example of a database stored in the storage unit 33 according to the second embodiment. In the first database 331a shown in Fig. 8, the property conditions of greenhouse gases are added to the transfer conditions of greenhouse gases. On the other hand, the second database 332 shows the same receiving conditions of greenhouse gases as in the first embodiment.

[0052] Thereafter, in step S108, the greenhouse gas property conditions of each first transactor 100 are displayed together with the determination results on the output unit 23 of each second communication terminal 20. Next, in step S110, each second transactor 200, while looking at the property conditions displayed on the output unit 23, selects the first transactor 100 with which they wish to trade and inputs the information into the input unit 21.

[0053] In this embodiment, the second database 332 shown in Fig. 8 may include greenhouse gas property conditions desired by each second transactor 200 as additions to the greenhouse gas receiving conditions. In this case, in step S106, the determination unit 32 compares the property conditions in the first database 331a with the property conditions in the second database 332 to determine the degree of condition suitability. At this time, the determination unit 32 determines the degree of suitability based on a preset degree of suitability according to the difference in the property conditions, as in the first embodiment. The determination results of the property conditions are transmitted to and displayed on each first communication terminal 10 and each second communication terminal 20.

[0054] According to the present embodiment described above, adding greenhouse gas property conditions to the delivery conditions makes it easier to select a trading partner and negotiate with them. This allows for appropriate and smooth transfer of greenhouse gases, further promoting the reduction of greenhouse gas emissions.

[0055] (Third embodiment) In the greenhouse gas exchange support service shown in Figure 1 described in the first embodiment, the second trader 200 wants to purchase greenhouse gas as cheaply as possible, while the first trader 100 wants to sell the recovered greenhouse gas for as much as possible.

[0056] Furthermore, in the greenhouse gas transfer support service shown in Figure 2 described in the first embodiment, the second trader 200 wants to receive as much money as possible, while the first trader 100 wants to have the captured carbon dioxide purchased as cheaply as possible.

[0057] Therefore, in the second embodiment, a remuneration generated from the transfer of greenhouse gases is added to the delivery conditions of the first transactor 100. In the case of the greenhouse gas transfer support service shown in FIG. 1, this remuneration is the amount of first remuneration 400 that the first transactor 100 receives from the second transactor 200. On the other hand, in the case of the greenhouse gas transfer support service shown in FIG. 2, this remuneration is the amount of second remuneration 500 that the first transactor 100 transfers to the second transactor 200.

[0058] The configuration of the greenhouse gas transfer support system used in this embodiment is similar to that of the greenhouse gas transfer support system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the greenhouse gas transfer support system according to this embodiment will be described, focusing on the differences from the first embodiment.

[0059] In this embodiment, in step S101 shown in Figure 4, when multiple first traders 100 operate the input unit 11 of their own first communication terminal 10 to input the greenhouse gas transfer conditions, they also input the reward.

[0060] The input reward is received by the communication unit 31 of the server device 30 together with other transfer conditions in step S103 and stored in the storage unit 33.

[0061] Fig. 9 is a diagram showing an example of a database stored in the storage unit 33 according to the third embodiment. In the first database 331b shown in Fig. 8, the reward generated by the transfer of greenhouse gases is added to the greenhouse gas transfer conditions. On the other hand, the second database 332 shows the greenhouse gas receiving conditions similar to those in the first embodiment.

[0062] Then, in step S108, the rewards of each first trader 100 are displayed together with the discrimination result on the output unit 23 of each second communication terminal 20. Next, in step S110, each second trader 200 selects a first trader 100 with whom they wish to trade while looking at the rewards displayed on the output unit 23, and inputs the selection into the input unit 21.

[0063] In this embodiment, the second database 332 shown in Fig. 9 may include the remuneration desired by each second transactor 200 as a condition for receiving greenhouse gases. In this case, in step S106, the determination unit 32 calculates the difference in amount between the remuneration in the first database 331a and the remuneration in the second database 332, and determines the remuneration based on a preset suitability level according to the calculated difference in amount. The determination result of the remuneration is transmitted to and displayed on each first communication terminal 10 and each second communication terminal 20.

[0064] According to the present embodiment described above, by adding the remuneration generated by the transfer of greenhouse gases to the transfer conditions, it becomes easier to select a trading partner and it is possible to reduce the effort of negotiating with a trading partner regarding the remuneration. This makes it possible to transfer greenhouse gases appropriately and smoothly, further promoting the reduction of greenhouse gas emissions.

[0065] (Fourth embodiment) In the first embodiment described above, the second transactor 200 may want to know the location of the greenhouse gas generation, since transportation may be required depending on how the collected greenhouse gas is delivered. Also, the first transactor 100 and the second transactor 200 may each want to generate and process greenhouse gas in the same area, thereby contributing to the area or local government by achieving local production and consumption.

[0066] Therefore, in the fourth embodiment, the location of greenhouse gas generation is added to the delivery conditions of the first trader 100. The location of greenhouse gas generation is, for example, the location of a thermal power plant or a steel mill.

[0067] The configuration of the greenhouse gas transfer support system used in this embodiment is similar to that of the greenhouse gas transfer support system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the greenhouse gas transfer support system according to this embodiment will be described, focusing on the differences from the first embodiment.

[0068] In this embodiment, in step S101 shown in Figure 4, when multiple first traders 100 operate the input unit 11 of their own first communication terminal 10 to input the greenhouse gas transfer conditions, they also input the location where the greenhouse gas is generated.

[0069] The input greenhouse gas generation locations are received by the communication unit 31 of the server device 30 together with other transfer conditions in step S103 and stored in the storage unit 33.

[0070] Fig. 10 is a diagram showing an example of a database stored in the storage unit 33 according to the fourth embodiment. In the first database 331c shown in Fig. 10, the greenhouse gas generation location condition is added to the greenhouse gas delivery conditions. On the other hand, the second database 332 shows the greenhouse gas receiving conditions similar to those in the first embodiment.

[0071] Thereafter, in step S108, the greenhouse gas emission locations of each first transactor 100 are displayed together with the determination results on the output unit 23 of each second communication terminal 20. Next, in step S110, each second transactor 200, while looking at the greenhouse gas emission locations displayed on the output unit 23, selects the first transactor 100 with which they wish to trade and inputs this information into the input unit 21.

[0072] In this embodiment, the second database 332 shown in Fig. 10 may include the greenhouse gas receiving location of each second transactor 200 as a condition for receiving greenhouse gases. In this case, in step S106, the determination unit 32 calculates the distance between the generation location in the first database 331a and the receiving location in the second database 332, and determines the compatibility based on the calculated distance. The location determination result is transmitted to and displayed on each first communication terminal 10 and each second communication terminal 20.

[0073] According to the present embodiment described above, adding the location of greenhouse gas generation to the delivery conditions makes it easier to select a trading partner and negotiate with the trading partner. This allows the transfer of greenhouse gases to proceed appropriately and smoothly, further promoting the reduction of greenhouse gas emissions.

[0074] (Fifth embodiment) In the first embodiment described above, if the greenhouse gas is, for example, carbon dioxide, the first transactor 100 can obtain environmental value, for example, J-Credits from the Ministry of the Environment, by reducing carbon dioxide emissions.

[0075] Therefore, in the fifth embodiment, for example, in the case of the greenhouse gas transfer support service shown in Figure 2, the first trader 100 does not give the second trader 200 the entire second remuneration 500 in money, but rather gives the first environmental value obtained by reducing carbon dioxide emissions as all or part of the second remuneration 500.

[0076] The configuration of the greenhouse gas transfer support system used in this embodiment is similar to that of the greenhouse gas transfer support system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the greenhouse gas transfer support system according to this embodiment will be described, focusing on the differences from the first embodiment.

[0077] In this embodiment, in step S101 shown in Figure 4, when multiple first traders 100 operate the input unit 11 of their own first communication terminal 10 to input a reward as one of the conditions for the transfer of greenhouse gases, they input, for example, the ratio between money and the first environmental value in the reward.

[0078] The input ratio is received by the communication unit 31 of the server device 30 together with other transfer conditions in step S103 and stored in the storage unit 33.

[0079] Fig. 11 is a diagram showing an example of a database stored in the storage unit 33 according to the fifth embodiment. In the first database 331d shown in Fig. 11, the ratio of money to the first environmental value in the remuneration generated from the transfer of greenhouse gases is added to the greenhouse gas transfer conditions. On the other hand, the second database 332 shows the greenhouse gas receiving conditions similar to those of the first embodiment.

[0080] Then, in step S108, the reward ratio of each first trader 100 is displayed together with the determination result on the output unit 23 of each second communication terminal 20. Next, in step S110, each second trader 200 selects a first trader 100 with whom they wish to trade while looking at the reward ratio displayed on the output unit 23, and inputs it into the input unit 21.

[0081] According to the present embodiment described above, the ratio of money to the first environmental value in the compensation generated by the transfer of greenhouse gases is added to the delivery conditions, thereby improving the degree of freedom in transactions and allowing for appropriate and smooth negotiations with trading partners regarding the selection of trading partners and compensation, thereby further promoting the reduction of greenhouse gas emissions.

[0082] (Sixth embodiment) In the first embodiment described above, if the greenhouse gas is, for example, carbon dioxide, the second trader 200 can obtain environmental value, for example, J-Credits from the Ministry of the Environment, by storing or converting the carbon dioxide into a valuable resource. Therefore, in the sixth embodiment, for example, in the case of the greenhouse gas transfer support service shown in Figure 1, the second trader 200 does not give the first trader 100 the entire first remuneration 400 in money, but rather gives the first trader 100 the second environmental value obtained by storing or converting carbon dioxide into a valuable resource as all or part of the first remuneration 400.

[0083] The configuration of the greenhouse gas transfer support system used in this embodiment is similar to that of the greenhouse gas transfer support system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the greenhouse gas transfer support system according to this embodiment will be described, focusing on the differences from the first embodiment.

[0084] In this embodiment, in step S102 shown in Figure 4, when multiple second traders 200 operate the input unit 21 of their own second communication terminal 20 to input a reward as one of the conditions for receiving greenhouse gases, they input, for example, the ratio between money and the second environmental value in the reward.

[0085] The input ratio is received by the communication unit 31 of the server device 30 together with other receiving conditions in step S103 and stored in the storage unit 33.

[0086] Fig. 12 is a diagram showing an example of a database stored in the storage unit 33 according to the sixth embodiment. In the first database 332a shown in Fig. 12, the ratio of money to the second environmental value in the remuneration generated from the transfer of greenhouse gases is added to the conditions for receiving greenhouse gases. On the other hand, the first database 331 shows the same conditions for transferring greenhouse gases as in the first embodiment.

[0087] Then, in step S107, the reward ratio of each second trader 200 is displayed together with the judgment result on the output unit 13 of each first communication terminal 10. Next, in step S109, each first trader 100, while looking at the reward ratio displayed on the output unit 13, selects the second trader 200 with whom he / she wishes to trade and inputs it into the input unit 21.

[0088] According to the present embodiment described above, the ratio of money to second environmental value in the compensation generated by the transfer of greenhouse gases is added to the conditions for receipt, thereby increasing the degree of freedom in transactions and allowing for appropriate and smooth negotiations with trading partners regarding the selection of trading partners and compensation, thereby further promoting the reduction of greenhouse gas emissions.

[0089] Seventh embodiment The operation of the greenhouse gas transfer support system 1 according to the first embodiment described above ends when the first communication terminal 10 and the second communication terminal 20 notify the communication terminal of the trading partner with which they wish to trade.

[0090] On the other hand, in the seventh embodiment, when the first transactor 100 or the second transactor 200 that receives the notification via the first communication terminal 10 or the second communication terminal 20 negotiates the terms of the transaction, the greenhouse gas transfer support system 1 is also used. Here, a method for negotiating the terms of the transaction using the greenhouse gas transfer support system 1 will be described with reference to Fig. 13 .

[0091] FIG. 13 is a sequence diagram showing an example of an operation sequence of the greenhouse gas transfer support system according to the seventh embodiment.

[0092] For example, when a first trader 100 receives a notice of a desire to trade, if the first trader 100 is not satisfied with the greenhouse gas receiving conditions of the second trader 200 that sent the notice, the first trader 100 operates the input unit 11 to input the desired trading conditions (step S201). The input data indicating the desired trading conditions is transmitted to the server device 30 by the communication unit 12.

[0093] In the server device 30, the communication unit 31 receives the input data (step S202). The data received by the communication unit 31 is stored in the storage unit 33 (step S203).

[0094] Next, the discrimination unit 32 discriminates the degree of deviation (first condition deviation) between the desired trading conditions stored in the memory unit 33 and the receiving conditions of the second transactor 200 stored in the second database 332 (step S204). In step S204, the discrimination unit 32 calculates, for example, the difference between the receiving period and receiving amount indicated in the desired trading conditions of the first transactor 100 and the receiving period and receiving amount indicated in the receiving conditions of the second transactor 200. Next, the discrimination unit 32 discriminates using a condition deviation degree that is preset according to the amount of difference between the desired trading conditions and the receiving conditions.

[0095] Next, the communication unit 31 transmits the determination result of the degree of deviation from the conditions to the second communication terminal 20 via the network 40 (step S205). At this time, the communication unit 31 transmits the determination result of the degree of deviation from the conditions only to the second communication terminal 20 of the second transactor 200 who is the negotiation partner.

[0096] In the second communication terminal 20, the determination result of the degree of deviation of conditions is received by the communication unit 22 and displayed by the output unit 23 (step S206). The second transactor 200 responds whether or not to accept the desired trading conditions of the first transactor 100 based on the determination result of the degree of deviation of conditions displayed on the output unit 23. Specifically, the second transactor 200 operates the input unit 21 to input a response (step S207). At this time, if the second transactor 200 does not accept the desired trading conditions of the first transactor 100, he or she may change the receiving conditions to more concessional conditions and input them into the input unit 21.

[0097] The response of the second transactor 200 is transmitted to the first communication terminal 10 by the communication unit 22. This response is received by the communication unit 12 of the first communication terminal 10 and displayed by the output unit 13 (step S208). If the second transactor 200 agrees to the desired trading conditions of the first transactor 100, the negotiation is concluded. Conversely, if the second transactor 200 does not agree to the desired trading conditions of the first transactor 100, the operations of steps S201 to S208 described above are repeated. In this way, by using the greenhouse gas transfer support system 1, negotiations can be repeated between the first transactor 100 and the second transactor 200.

[0098] In addition, when the second transactor 200 receives a notice of desire to trade, the first communication terminal 10 and the second communication terminal 20 are the subjects of the operations in the above-mentioned steps S201 to S208. For example, in step S201, the second communication terminal 20 transmits desired trading conditions to the server device 30. In addition, in step S204, the determination unit 32 of the server device 30 determines the desired trading conditions of the second transactor 200 who received the notice of desire to trade based on a predetermined condition deviation degree (second condition deviation degree) according to the amount of difference between the desired trading conditions of the second transactor 200 who received the notice of desire to trade and the delivery conditions of the first transactor 100 who sent the notice. Subsequently, in step S205, the server device 30 transmits this condition deviation degree to the first communication terminal 10. Furthermore, in step S207, the first communication terminal 10 transmits the response of the first transactor 100 to the second communication terminal 20. At this time, if the first transactor 100 does not agree to the desired transaction conditions of the second transactor 200, the first transactor 100 may change the delivery conditions to more concessional conditions and input them into the input unit 11.

[0099] In this embodiment, the first transactor 100 and the second transactor 200 may be able to communicate with each other on the greenhouse gas transfer support system 1 using the first communication terminal 10 and the second communication terminal 20. In this case, the convenience of negotiations on transaction terms and the like is improved, making it easier to reach a transaction agreement.

[0100] According to the present embodiment described above, greenhouse gas transactions proceed appropriately and smoothly, making it possible to further promote the reduction of greenhouse gas emissions.

[0101] (Eighth embodiment) In the first embodiment described above, the greenhouse gas transfer support system 1 deals with a variety of greenhouse gases 300, including carbon dioxide, chlorofluorocarbons, and hydrocarbons. However, chlorofluorocarbons are often recovered when equipment that uses them as refrigerants is disposed of. In addition, there are often very few hydrocarbons that are unused and can be recovered.

[0102] Therefore, in the greenhouse gas transfer support system 1 according to this embodiment, carbon dioxide, which is easily traded, is the trading target greenhouse gas 300. Therefore, the greenhouse gas transfer support system according to this embodiment is a platform limited to carbon dioxide.

[0103] FIG. 14 is a diagram showing an example of a database stored in the storage unit 33 according to the eighth embodiment. As described above, in this embodiment, the type of greenhouse gas is limited to carbon dioxide. Therefore, in the first database 332e shown in FIG. 14, the type of greenhouse gas is excluded from the greenhouse gas transfer conditions. Similarly, in the second database 332b shown in FIG. 14, the type of greenhouse gas is excluded from the greenhouse gas reception conditions. This reduces the amount of data stored in the database 330 of the storage unit 33, thereby reducing the storage capacity of the storage unit 33.

[0104] According to the present embodiment described above, the type of greenhouse gas is limited to carbon dioxide, eliminating the need for information indicating the type of substance the greenhouse gas is, which allows for smoother trading of carbon dioxide and promotes the reduction of carbon dioxide emissions.

[0105] (Ninth embodiment) 15 is a schematic diagram for explaining a greenhouse gas transfer support service according to a ninth embodiment. A greenhouse gas transfer support system 1 according to this embodiment is communicatively connected to a payment system 2. Specifically, a server device 30 is communicatively connected to the payment system 2. Note that the server device 30 may be directly connected to the payment system 2, or may be connected via a network 40.

[0106] In this embodiment, for example, the communication unit 31 of the server device 30 receives a notification indicating that a transaction has been concluded from the first communication terminal 10 or the second communication terminal 20. Next, the communication unit 31 reads out the receiving conditions or the transferring conditions stored in the memory unit 33 for the first remuneration 400 to be paid from the second transactor 200 to the first transactor 100, or the second remuneration 500 to be paid from the first transactor 100 to the second transactor 200. Next, the communication unit 31 transfers the read out first remuneration 400 or second remuneration 500 to the settlement system 2.

[0107] The settlement system 2 performs a process of paying the first remuneration 400 to the first transactor 100 or a process of paying the second remuneration 500 to the second transactor 200. Here, an example of the payment process of the first remuneration 400 and the second remuneration 500 will be described. However, the content of the payment process is not limited to the following method.

[0108] The identification numbers of the first transactor 100 and the second transactor 200 are transferred to the settlement system 2 from the communication unit 31 along with the first remuneration 400 or the second remuneration 500. The settlement system 2 also stores a database that associates the above identification numbers with account numbers. The settlement system 2 reads out the account numbers corresponding to the respective identification numbers of the first transactor 100 and the second transactor 200 from the above database. The settlement system 2 then performs a process of withdrawing the amount of the first remuneration 400 from the account number of the second transactor 200 and transferring it to the account number of the first transactor 100, or a process of withdrawing the amount of the second remuneration 500 from the account number of the first transactor 100 and transferring it to the account number of the second transactor 200.

[0109] According to the present embodiment described above, the payment process is smoother because the payment system 2 performs the process of paying the first remuneration 400 and the second remuneration 500. As a result, the convenience of the greenhouse gas transfer support service is further improved, which makes it possible to further promote the reduction of greenhouse gas emissions.

[0110] Although several embodiments have been described above, these embodiments are presented only as examples and are not intended to limit the scope of the invention. The novel system described in this specification can be embodied in various other forms. Furthermore, various omissions, substitutions, and modifications can be made to the forms of the system described in this specification without departing from the spirit of the invention. The appended claims and their equivalents are intended to cover such forms and modifications that fall within the scope and spirit of the invention. [Explanation of symbols]
