Description

Embodiments of the present invention relate to a greenhouse gas transfer support system, a greenhouse gas transfer support method, and a program.

Tackling global warming is a global issue, and in order to reduce greenhouse gases, technologies such as carbon dioxide capture and storage are being applied. 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.

Technology for effectively utilizing captured carbon dioxide is also being developed. For example, this technology involves injecting carbon dioxide into old oil fields, which uses pressure to push out the remaining crude oil while storing the carbon dioxide underground. In this case, it also leads to increased oil production.

In addition, efforts are underway to use carbon dioxide as a resource to produce valuable products such as chemicals and fuels.

Japanese Patent Application Publication No. 8-127544

As mentioned above, reducing emissions of greenhouse gases such as carbon dioxide is recommended, and an increasing number of companies and organizations are looking to reduce their greenhouse gas emissions.

However, even if greenhouse gases are captured at great expense, they cannot be handed over unless a company or organization partners with a company or organization that receives, stores, or effectively utilizes 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.

The problem that this invention aims to solve 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.

In one embodiment, a greenhouse gas transfer support system includes a first communication terminal used by a first trader that transfers greenhouse gases, a second communication terminal used by a second trader that receives greenhouse gases, and a server device connected to the first and second communication terminals via a network. The server device has a memory unit that stores the greenhouse gas transfer conditions of the first trader received from the first communication terminal and the greenhouse gas reception conditions of the second trader received from the second communication terminal, respectively, and a discrimination unit that determines the degree of conformity between the transfer conditions and the reception conditions. The first communication terminal has 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 of 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's selection of the first trader with whom he wishes to trade based on the determination results.

This embodiment makes it possible to promote the reduction of carbon dioxide emissions.

Embodiments of the present invention will be described below with reference to the drawings. The following embodiments do not limit the present invention.

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

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.

In FIG. 1, at least one first trader 100 is registered in the Greenhouse Gas Transfer Support System 1 as a greenhouse gas transferor. At least one second trader 200 is also registered in the Greenhouse Gas Transfer Support System 1 as a greenhouse gas receiver. The second trader 200 is a company that makes effective use of greenhouse gases, for example, a company that produces valuable materials using carbon dioxide as a raw material. The first trader 100 and the second trader 200 may be individuals, groups, or organizations. The first trader 100 and the second trader 200 may be singular or plural.

The first trader 100 can select a trading partner from among the second traders 200 registered in the greenhouse gas transfer support system 1. Meanwhile, the second trader 200 can also select a trading partner from among the first traders 100 registered in the greenhouse gas transfer support system 1. When the first trader 100 and the second trader 200 enter into a mutually selected relationship, they conduct trade negotiations. Trade negotiations include negotiating the trade volume, trade period, forward delivery terms, and the like. After the trade is concluded, the transfer of greenhouse gases, such as carbon dioxide, is realized. In FIG. 1, greenhouse gases 300 are transferred from the first trader 100 to the second trader 200, and a first remuneration 400 is transferred from the second trader 200 to the first trader 100. This first remuneration 400 is, for example, money.

Figure 2 is a schematic diagram illustrating another greenhouse gas transfer support service using the greenhouse gas transfer support system.

In Figure 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 recovery is carried out in order to reduce carbon dioxide emissions, but there are often few second transactors 200 who can accept the carbon dioxide due to reasons such as difficulties in transportation. In this case, carbon dioxide recovery does not progress easily. Therefore, the first transactor 100 is willing to pay money to have the second transactor 200 accept the carbon dioxide. 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 will negotiate a transaction. When the transaction is concluded, the first transactor 100 transfers the second remuneration 500 along with the greenhouse gas 300 to the second transactor 200, while nothing is transferred from the second transactor 200 to the first transactor 100.

Figure 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.

The first communication terminal 10 is used by the first trader 100 and is realized, for example, by a personal computer or smartphone. 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).

The input unit 11 functions as an input interface that accepts input operations by the first trader 100. The input unit 11 is composed of, for example, a keyboard, mouse, touch panel, etc.

The communication unit 12 communicates with the server device 30 via the network 40. When communicating with the server device 30, the communication unit 12 transmits input data received through operation of the input unit 11 to the server device 30. The communication unit 12 also receives various data from the server device 30.

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, as a liquid crystal display.

The second communication terminal 20 is used by the second trader 200 and is realized, for example, by a personal computer or 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.

Note that the four "..." symbols in Figure 3 indicate that in the greenhouse gas transfer support system 1, multiple first communication terminals 10 and multiple 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, there is no particular limit on the number of first communication terminals 10 and second communication terminals 20, and the number may be one.

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

The discrimination unit 32 performs various discrimination operations based on data stored in the memory unit 33. The discrimination unit 32 is composed of, for example, a CPU (Central Processing Unit) that performs calculations based on a predetermined program (software).

The memory unit 33 stores data regarding greenhouse gases, including the delivery conditions of each first trader 100 and the receiving conditions of each second trader 200. The memory unit 33 is composed of, for example, a hard disk or semiconductor memory.

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 the 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.

In the sequence diagram shown in Figure 4, first, multiple first traders 100 operate the input unit 11 of their own first communication terminal 10 to input greenhouse gas transfer conditions (step S101). The greenhouse gas transfer conditions include, for example, the type of greenhouse gas to be transferred, the transfer period, and the transfer amount. The first input data indicating the greenhouse gas transfer 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 transfer number for identifying each first trader 100.

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.

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

Figure 5 is a diagram showing an example of a database stored in the memory unit 33 according to the first embodiment. As shown in Figure 5, the database 330 is composed of a first database 331 and a second database 332. The first database 331 shows the greenhouse gas delivery conditions entered into 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 entered into 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 Figure 5.

Once the database 330 is created in the memory unit 33, the discrimination unit 32 then determines the degree of conformance between the delivery conditions and the receipt conditions, or the condition feasibility indicating whether the conditions are met, for each of the multiple first traders 100 and the multiple second traders 200 based on this database 330 (step S105). Here, we will explain one example of how the discrimination unit 32 determines the degree of conformance.

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 suitability is 100%, and if they do not match, determines that the degree of condition suitability is 0%.

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 trader 100 and the receipt period and receipt amount indicated in the receipt conditions of each second trader 200. The discrimination unit 32 then calculates the degree of condition conformance according to the amount of difference between the delivery conditions and the receipt conditions. At this time, the degree of condition conformance is preset according to the amount of difference. For example, if the delivery period is one year, and the matching period within the receipt period is six months, the degree of condition conformance is 50% (= (6/12) x 100). Furthermore, if the delivery amount is 100 t and the receipt amount is 200 t, the degree of condition conformance is 200% (= (200/100) x 100).

Once the determination unit 32 determines the degree of conformance to the above conditions for all combinations of first traders 100 and all second traders 200, the communication unit 31 transmits the determination 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 determination results for each first trader 100 identified by the delivery number and each second trader 200 identified by the receipt number.

At the first communication terminal 10, the determination result is received by the communication unit 12 and displayed by the output unit 13 (step S107). Meanwhile, at the second communication terminal 20, the determination result is received by the communication unit 22 and displayed by the output unit 23 (step S108).

Figure 6 is a diagram showing an example of the determination result displayed on the first communication terminal 10. The image 130 shown in Figure 6 is the determination result displayed on the first communication terminal 10 of the first trader 100 identified by the delivery number 100a. Therefore, this image 130 displays the degree of suitability of the receiving conditions of each second trader 200 with the delivery conditions of this first trader 100.

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 trader 200 identified by the receipt number 200a. Therefore, this image 230 displays the degree of suitability of the delivery conditions of each first trader 100 with the receipt conditions of this second trader 200.

When the condition suitability judgment results 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, selects a second trader 200 with whom they wish to trade, and inputs this information 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, selects a first trader 100 with whom they wish to trade, and inputs this information into the input unit 21 (step S110).

When the input unit 11 accepts the selection input from the second trader 200, the communication unit 12 notifies the second communication terminal 20 of the selection result (step S111). This notification is displayed on the output unit 23 of the second communication terminal.

On the other hand, when the input unit 21 accepts the selection input from the first trader 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.

If the first transactor 100 then inputs the second transactor 200 as a potential transactor, the second transactor 200 will determine whether or not to transact with the first transactor 100. 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 potential transactor, 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.

According to the present embodiment described above, the greenhouse gas transfer support system 1 can be used to connect companies and organizations that wish to transfer greenhouse gases with companies and organizations that wish to receive greenhouse gases, thereby facilitating transactions. This makes it possible to promote the reduction of greenhouse gas emissions.

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, there may be cases where the second trader 200 does not want to receive the recovered carbon dioxide depending on its purity, particularly the type and amount of impurities other than carbon dioxide.

Therefore, in the second embodiment, greenhouse gas property conditions are added to the delivery conditions of the first trader 100. Greenhouse gas property conditions include, for example, the pressure and temperature of the greenhouse gas, and the type and amount of impurities contained in the greenhouse gas.

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, so a detailed description will be omitted. Here, the operational sequence of the greenhouse gas transfer support system according to this embodiment will be described, focusing on the differences from the first embodiment.

In this embodiment, in step S101 shown in FIG. 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.

The entered greenhouse gas property conditions are received by the communication unit 31 of the server device 30 along with other transfer conditions in step S103 and stored in the memory unit 33.

Figure 8 is a diagram showing an example of a database stored in the memory unit 33 according to the second embodiment. In the first database 331a shown in Figure 8, greenhouse gas property conditions have been 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.

Then, in step S108, the greenhouse gas property conditions of each first trader 100 are displayed on the output unit 23 of each second communication terminal 20 along with the determination results. Next, in step S110, each second trader 200, while viewing the property conditions displayed on the output unit 23, selects the first trader 100 with whom they wish to trade and inputs them into the input unit 21.

In this embodiment, the second database 332 shown in FIG. 8 may include greenhouse gas property conditions desired by each second trader 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, as in the first embodiment, the determination unit 32 determines the degree of suitability based on a preset degree of suitability depending on the difference in property conditions. The property condition determination results are transmitted to and displayed on each first communication terminal 10 and each second communication terminal 20.

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.

(Third embodiment)
In the greenhouse gas transfer 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.

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

In the second embodiment, therefore, 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.

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, so a detailed description will be omitted. Here, the operational sequence of the greenhouse gas transfer support system according to this embodiment will be described, focusing on the differences from the first embodiment.

In this embodiment, in step S101 shown in FIG. 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 remuneration.

The entered reward, along with other transfer conditions, is received by the communication unit 31 of the server device 30 in step S103 and stored in the memory unit 33.

Figure 9 is a diagram showing an example of a database stored in the memory unit 33 according to the third embodiment. In the first database 331b shown in Figure 8, the rewards generated from the transfer of greenhouse gases are 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.

Then, in step S108, the rewards of each first trader 100 are displayed on the output unit 23 of each second communication terminal 20 along with the determination result. Next, in step S110, each second trader 200, while viewing the rewards displayed on the output unit 23, selects the first trader 100 with whom they wish to trade and inputs this information into the input unit 21.

In this embodiment, the second database 332 shown in FIG. 9 may include the remuneration desired by each second trader 200 as a condition for receiving greenhouse gases. In this case, in step S106, the determination unit 32 calculates the monetary difference between the remuneration in the first database 331a and the remuneration in the second database 332, and determines the degree of suitability set in advance according to the calculated monetary difference. The remuneration determination result is transmitted to and displayed on each first communication terminal 10 and each second communication terminal 20.

According to the present embodiment described above, by adding the reward generated from the transfer of greenhouse gases to the transfer conditions, it becomes easier to select a trading partner and reduces the effort required to negotiate with the trading partner regarding the reward. This allows the transfer of greenhouse gases to proceed appropriately and smoothly, further promoting the reduction of greenhouse gas emissions.

(Fourth embodiment)
In the first embodiment described above, depending on how the collected greenhouse gas is delivered, the second trader 200 may need to transport the greenhouse gas, and may want to know where the greenhouse gas is generated. In addition, each of the first trader 100 and the second trader 200 may 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.

Therefore, in the fourth embodiment, the location of greenhouse gas generation is added to the delivery conditions of the first trader 100. Examples of greenhouse gas generation locations include the locations of thermal power plants and steel mills.

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, so a detailed description will be omitted. Here, the operational sequence of the greenhouse gas transfer support system according to this embodiment will be described, focusing on the differences from the first embodiment.

In this embodiment, in step S101 shown in FIG. 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.

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

Figure 10 is a diagram showing an example of a database stored in the memory unit 33 according to the fourth embodiment. In the first database 331c shown in Figure 10, the greenhouse gas generation location conditions have been 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.

Then, in step S108, the greenhouse gas emission locations of each first trader 100 are displayed on the output unit 23 of each second communication terminal 20 along with the determination results. Next, in step S110, each second trader 200, while viewing the greenhouse gas emission locations displayed on the output unit 23, selects the first trader 100 with which they wish to trade and inputs this information into the input unit 21.

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 degree of suitability based on the calculated distance. The location determination results are transmitted to and displayed on each first communication terminal 10 and each second communication terminal 20.

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 them. This allows for the appropriate and smooth transfer of greenhouse gases, further promoting the reduction of greenhouse gas emissions.

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

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 cash, but rather gives the first environmental value obtained by reducing carbon dioxide emissions as all or part of the second remuneration 500.

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, so a detailed description will be omitted. Here, the operational sequence of the greenhouse gas transfer support system according to this embodiment will be described, focusing on the differences from the first embodiment.

In this embodiment, in step S101 shown in FIG. 4, when multiple first traders 100 operate the input unit 11 of their own first communication terminal 10 to input a remuneration as one of the greenhouse gas transfer conditions, they input, for example, the ratio of money to the first environmental value in the remuneration.

The entered ratio is received by the communication unit 31 of the server device 30 along with other transfer conditions in step S103 and stored in the memory unit 33.

Figure 11 is a diagram showing an example of a database stored in the memory unit 33 according to the fifth embodiment. In the first database 331d shown in Figure 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.

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

According to the present embodiment described above, the ratio of money to first environmental value in the compensation generated from the transfer of greenhouse gases is added to the delivery conditions, 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. This makes it possible to further promote the reduction of greenhouse gas emissions.

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 second environmental value obtained by storing or converting carbon dioxide into a valuable resource as all or part of the first remuneration 400.

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, so a detailed description will be omitted. Here, the operational sequence of the greenhouse gas transfer support system according to this embodiment will be described, focusing on the differences from the first embodiment.

In this embodiment, in step S102 shown in FIG. 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 of money to the second environmental value in the reward.

The entered ratio, along with other receiving conditions, is received by the communication unit 31 of the server device 30 in step S103 and stored in the memory unit 33.

Figure 12 is a diagram showing an example of a database stored in the memory unit 33 according to the sixth embodiment. In the first database 332a shown in Figure 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.

Then, in step S107, the reward ratio of each second trader 200 is displayed on the output unit 13 of each first communication terminal 10 along with the judgment result. 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 they wish to trade and inputs this into the input unit 21.

According to the present embodiment described above, the ratio of money to second environmental value in the compensation generated from the exchange 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. This makes it possible to further promote the reduction of greenhouse gas emissions.

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.

In the seventh embodiment, the first transactor 100 or the second transactor 200, which receives the notification via the first communication terminal 10 or the second communication terminal 20, also uses the greenhouse gas transfer support system 1 when negotiating the terms of the transaction. Here, with reference to FIG. 13, a method for negotiating the terms of the transaction using the greenhouse gas transfer support system 1 will be described.

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

For example, when a first trader 100 receives a notification 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 notification, 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.

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 memory unit 33 (step S203).

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 trader 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 trader 100 and the receiving period and receiving amount indicated in the receiving conditions of the second trader 200. Next, the discrimination unit 32 discriminates using a condition deviation degree that is preset according to the difference between the desired trading conditions and the receiving conditions.

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 negotiating partner.

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 trader 200 responds whether or not they will accept the desired trading conditions of the first trader 100 based on the determination result of the degree of deviation of conditions displayed on the output unit 23. Specifically, the second trader 200 operates the input unit 21 to input a response (step S207). At this time, if the second trader 200 does not accept the desired trading conditions of the first trader 100, they may change the receiving conditions to more concessional conditions and input them into the input unit 21.

The second transactor 200's response 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, negotiations are 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.

Note that if the second trader 200 receives a notice of a 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 the desired trading conditions to the server device 30. Also, in step S204, the discrimination unit 32 of the server device 30 discriminates 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 trader 200 who received the notification of a desire to trade and the delivery conditions of the first trader 100 who sent the notification. Next, 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 trader 100 to the second communication terminal 20. At this time, if the first trader 100 does not agree to the trading conditions desired by the second trader 200, the first trader 100 may change the delivery conditions to more concessional conditions and input them into the input unit 11.

Furthermore, in this embodiment, the first transactor 100 and the second transactor 200 may be able to communicate 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.

According to the present embodiment described above, greenhouse gas transactions can be carried out appropriately and smoothly, further promoting the reduction of greenhouse gas emissions.

Eighth Embodiment
In the first embodiment described above, the greenhouse gas transfer support system 1 trades multiple types of greenhouse gases 300, such as 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.

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

Figure 14 is a diagram showing an example of a database stored in the memory 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 Figure 14, the type of greenhouse gas is excluded from the greenhouse gas transfer conditions. Similarly, in the second database 332b shown in Figure 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 memory unit 33, thereby reducing the storage capacity of the memory unit 33.

According to the present embodiment described above, by limiting the type of greenhouse gas to carbon dioxide, there is no need for information indicating what type of substance the greenhouse gas is. This makes it possible to more smoothly trade carbon dioxide and promote the reduction of carbon dioxide emissions.

Ninth Embodiment
15 is a schematic diagram for explaining a greenhouse gas transfer support service according to the 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.

In this embodiment, for example, the communication unit 31 of the server device 30 receives a notification from the first communication terminal 10 or the second communication terminal 20 indicating that a transaction has been concluded. Next, the communication unit 31 reads out the receipt conditions or delivery 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 first remuneration 400 or second remuneration 500 to the payment system 2.

The payment system 2 performs a process of paying the first remuneration 400 to the first trader 100 or a process of paying the second remuneration 500 to the second trader 200. Here, an example of the payment process for 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.

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

According to the present embodiment described above, the payment system 2 handles the process of paying the first remuneration 400 and the second remuneration 500, which also facilitates the payment process. As a result, the convenience of the greenhouse gas transfer support service is further improved, making it possible to further promote the reduction of greenhouse gas emissions.
