Description

[Technical Field]

[0001] The embodiments of the present invention relate to an environmental value trading system, an environmental value trading method, and a program. [Background technology]

[0002] In recent years, the issue of global warming has received significant attention, and the reduction of carbon dioxide emissions has been recommended. As a result, an increasing number of companies and organizations are looking to reduce their carbon dioxide emissions. In addition, carbon trading has become popular, with non-fossil certificates for electricity generated from renewable energy being issued for a fee, and as a result, an increasing number of companies and organizations are reducing their actual carbon dioxide emissions.

[0003] Reducing carbon dioxide emissions or net emissions is not only a response to social demands, but also improves the image of companies and organizations, and can be a factor in investment decisions for corporations. For corporate publicity purposes, many companies are issuing press releases announcing investments in renewable energy-related companies and switching to electric vehicles for company cars.

[0004] As a result, environmental value trading has become popular worldwide. Examples of environmental value include carbon dioxide emission rights, which are bought and sold. The Ministry of the Environment's J-Credit program values ​​the introduction of renewable energy, upgrading to energy-saving equipment, and forest conservation, which fixes carbon dioxide. A bilateral crediting mechanism has also been established. Non-fossil certificates and green power / heat certificates for electricity generated from renewable energy sources are also in circulation. The Green Life Point program, which issues points to individual consumers who take environmentally conscious actions such as reducing food waste and clothing waste, was launched in fiscal 2022.

[0005] [Patent Document 1] Patent Publication No. 2021-111294 Summary of the Invention [Problem to be solved by the invention]

[0006] If there are those who create environmental value such as renewable energy and those who buy it and offset its carbon emissions, the payment for the environmental value can be used as funds for the creator, further promoting renewable energy. Under the METI FIT system, subsidies given to renewable energy generators were paid for by taxpayers' money, but with this system, environmental value will be traded voluntarily, further promoting power generation using renewable energy.

[0007] Creating tradeable environmental value improves the image of companies and organizations as proactive in combating global warming, leading to increased publicity. Furthermore, the efforts to create value can be visualized in concrete figures, which can lead to increased motivation and a change in mindset among members of companies and organizations. Those who offset carbon also increase their spending, raising awareness. These efforts will also further promote activities that lead to environmental protection. They will also educate individuals and advance activities in daily life outside of the efforts of companies and organizations.

[0008] In this way, environmental protection will progress as environmental value trading progresses, so it is expected that increasing the variety of environmental values ​​and making environmental value trading more active will further advance environmental protection. Note that environmental protection does not only mean reducing carbon dioxide emissions, but also includes the protection of nature, water, and other environmental aspects.

[0009] The problem to be solved by the present invention is to provide an environmental value trading system, an environmental value trading method, and a program that can stimulate environmental value trading. [Means for solving the problem]

[0010] An environmental value trading system according to one embodiment includes a first communication terminal used by a first transactor that transfers an environmental value authenticated by an authenticator, a second communication terminal used by a second transactor that receives the environmental value, 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 first transactor's conditions for transferring the environmental value received from the first communication terminal and the second transactor's conditions for receiving the environmental value received from the second communication terminal, and a discrimination unit that discriminates 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 transactor of the result of the first transactor's selection of a second transactor with whom the first transactor 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]

[0013] 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.

[0014] (First embodiment) FIG. 1 is a schematic diagram for explaining the trading of environmental values ​​using an environmental value trading system.

[0015] The environmental value trading system 1 shown in Figure 1 brings together a first transactor 100, who transfers an environmental value 400, and a second transactor 200, who receives the environmental value 400 and transfers payment 500 to the first transactor 100. The environmental value trading system 1 is, for example, a computer system connected to a website, and can be used by anyone who has a personal computer or smartphone connected to the Internet.

[0016] In the first embodiment, the environmental value 400 is the amount of reduction in emissions of environmentally harmful substances other than carbon dioxide. On the other hand, the compensation 500 may be money or another environmental value, and is not particularly limited.

[0017] Carbon dioxide emission credits, carbon dioxide reductions, and actual carbon dioxide emissions related to life cycle assessments are traded as environmental values. Carbon dioxide emissions are huge, so they are easy to trade. On the other hand, there are other substances besides carbon dioxide that are harmful to the environment, so it is desirable to reduce emissions of these harmful substances as well.

[0018] Substances that are harmful to the environment include greenhouse gases such as chlorofluorocarbons, methane, and nitrous oxide. While chlorofluorocarbons are widely used as refrigerants, they can leak during production, use, and disposal. Methane is released into the atmosphere by livestock and some geothermal power plants. Excessive use of methane in agricultural fertilizers can also release nitrous oxide.

[0019] The amount of environmental value 400 (for example, the amount of carbon dioxide reduction) is guaranteed by receiving certification 600 from a certifier 300. The certifier 300 is, for example, a public institution or a company or organization commissioned by a public institution. Appropriate certification 600 from a certifier 300 can prevent greenwashing, which is the false appearance of environmental considerations.

[0020] 2 is a block diagram showing the configuration of an environmental value trading system 1 according to the first embodiment. The environmental value trading 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.

[0021] The first communication terminal 10 is used by the first transactor 100 and is realized by, for example, a personal computer or a 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 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. Furthermore, the four "···" symbols in FIG. 2 indicate that, in the environmental value trading system 1, a plurality of first communication terminals 10 and a plurality of second communication terminals 20 are respectively connected to the server device 30 via the network 40. However, in the environmental value trading system 1, the number of first communication terminals 10 and second communication terminals 20 is not particularly limited and may be one.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 2 shows only one first communication terminal 10 and one second communication terminal 20. However, in the environmental value trading system 1, a plurality of first communication terminals 10 used by a plurality of first transactors 100 and a plurality of second communication terminals 20 used by a plurality of second transactors 200 may be connected to the server device 30 via the network 40.

[0027] 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.

[0028] 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).

[0029] The storage unit 33 stores data regarding the environmental value 400, 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.

[0030] The operation of the environmental value trading system 1 will be described below with reference to Fig. 3. Fig. 3 is a sequence diagram showing an example of an operation sequence of the environmental value trading 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.

[0031] In the sequence diagram shown in Figure 3, first, multiple first transactors 100 operate the input unit 11 of their own first communication terminal 10 to input the conditions for transferring the environmental value (step S101). The conditions for transferring the environmental value include, for example, the amount of environmental value to be transferred (in this embodiment, the amount of reduction in emissions of environmentally harmful substances other than carbon dioxide), whether or not authentication 600 has been obtained from the certifier 300, and the compensation desired to be received from the second transactor 200. The first input data indicating the conditions for transferring the environmental value entered 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 transactor 100.

[0032] In parallel with step S101, a plurality of second transactors 200 operate the input units 21 of their own second communication terminals 20 to input the conditions for receiving the environmental value (step S102). The conditions for receiving the environmental value include, for example, the amount of environmental value to be received (specifically, the amount of reduction in emissions of environmentally harmful substances other than carbon dioxide), whether or not authentication 600 by the certifier 300 is required, and the compensation to be paid to the first transactor 100. The second input data indicating the conditions for receiving the environmental value 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 reception number for identifying each second transactor 200.

[0033] 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).

[0034] Fig. 4 is a diagram showing an example of a database stored in the storage unit 33 according to the first embodiment. As shown in Fig. 4, the database 330 is made up of a first database 331 and a second database 332. The first database 331 shows the environmental value transfer conditions input to each first communication terminal 10 in step S101 in association with a transfer number. On the other hand, the second database 332 shows the environmental value receipt conditions input to each second communication terminal 20 in step S102 in association with a receipt number. It should be noted that the structure of the database 330 is not limited to the example shown in Fig. 4.

[0035] 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 for each of the plurality of first transactors 100 and the plurality of 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.

[0036] For example, the discrimination unit 32 calculates the difference between the emission reduction amount of environmentally hazardous substances indicated in the delivery conditions of multiple first traders 100 identified by delivery numbers and the emission reduction amount of environmentally hazardous substances indicated in the receipt conditions of each second trader 200. Next, the discrimination unit 32 calculates the degree of condition conformance according to the difference between the delivery conditions and the receipt conditions. At this time, the degree of condition conformance is preset according to the difference amount. For example, if the emission reduction amount in the delivery conditions is 1 ton and the emission reduction amount in the receipt conditions is 2 ton, the degree of condition conformance is 200% (= (2 / 1) × 100). Also, for example, if the desired price in the delivery conditions is 1 million yen and the price in the receipt conditions is 500,000 yen, the degree of condition conformance is 50% (= (50 / 100) × 100).

[0037] Furthermore, for example, with regard to the certification 600 of environmental value by the certifier 300, the handover condition is assumed to be "0" indicating that certification is given and "1" indicating that certification is not given, and the receiving condition is assumed to be "0" and "1" indicating that certification is not given. In this case, the discriminator 32 determines that the degree of conformance of the conditions is 100% when the numerical values ​​of both conditions match, and 0% when they do not match.

[0038] 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.

[0039] 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).

[0040] Figure 5 is a diagram showing an example of the determination result displayed on the first communication terminal 10. The image 130 shown in Figure 5 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.

[0041] Fig. 6 is a diagram showing an example of the determination result displayed on the second communication terminal 20. The image 230 shown in Fig. 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.

[0042] 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).

[0043] 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.

[0044] 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.

[0045] Thereafter, if the first transactor 100 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. 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 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, trading of environmental value is realized.

[0046] According to the present embodiment described above, it is possible to promote transactions by connecting companies and organizations that wish to transfer environmental value with companies and organizations that wish to receive environmental value via the environmental value trading system 1. This makes it possible to stimulate environmental value trading and promote environmental protection. In particular, this embodiment can promote the reduction of emissions of environmentally harmful substances other than carbon dioxide.

[0047] If the environmental value 400 and the consideration 500 can be exchanged electronically, after the transaction is concluded, the environmental value 400 is transmitted as electronic data from the communication unit 12 of the first communication terminal 10 to the communication unit 22 of the second communication terminal 20 via the network 40. On the other hand, the consideration 500 is transmitted as electronic money from the communication unit 22 of the second communication terminal 20 to the communication unit 12 of the first communication terminal 10 via the network 40. In this case, the environmental value trading system 1 can not only perform the process of matching trading partners for the environmental value, but also the process of exchanging the environmental value 400, and can also perform the process of paying the consideration 500 without using the payment system 2 described below (in a nineteenth embodiment). This can improve the convenience of environmental value trading.

[0048] (Second embodiment) The second embodiment differs from the first embodiment in the type of environmental value 400. The environmental value 400 of this embodiment is the amount of reduction in the amount of emissions of substances harmful to the human body.

[0049] Because the human body is part of the environment in a broad sense, it is desirable to include in the environmental value the reduction in emissions of substances harmful to the human body. Substances harmful to the human body include, for example, nitrogen oxides, sulfur oxides, formaldehyde, photochemical oxidants, fine particulate matter (PM2.5), asbestos, dioxins, and heavy metals. The amount of reduction in emissions of such substances, i.e., the amount of environmental value 400 in this embodiment, is guaranteed by the certification 600 of the certifier 300, as in the first embodiment.

[0050] The configuration of the environmental value trading system used in this embodiment is the same as that of the environmental value trading system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the environmental value trading system according to this embodiment will be described, focusing on the differences from the first embodiment.

[0051] In this embodiment, in step S101 shown in Figure 3, when a plurality of first transactors 100 operate the input unit 11 of their own first communication terminal 10 to input the conditions for transferring the environmental value, they input the amount of emission reduction of substances harmful to the human body as the amount of environmental value to be transferred. Also, in step S102, when a plurality of second transactors 200 operate the input unit 21 of their own second communication terminal 20 to input the conditions for receiving the environmental value, they input the amount of emission reduction of substances harmful to the human body as the amount of environmental value to be received.

[0052] The emission reduction amount of substances harmful to the human body input in step S101 is received by the communication unit 31 of the server device 30 together with other delivery conditions in step S103 and stored in the memory unit 33. On the other hand, the emission reduction amount of substances harmful to the human body input in step S102 is also received by the communication unit 31 of the server device 30 together with other receiving conditions in step S103 and stored in the memory unit 33.

[0053] Fig. 7 is a diagram showing an example of a database stored in the storage unit 33 according to the second embodiment. The first database 331a shown in Fig. 7 stores the amount of emission reduction of substances harmful to the human body as one of the conditions for transferring the environmental value. Meanwhile, the second database 332a also stores the amount of emission reduction of substances harmful to the human body as one of the conditions for receiving the environmental value.

[0054] Then, in step S105, the discrimination unit 32 calculates the difference between the emission reduction amount of substances harmful to the human body in the delivery condition and the emission reduction amount of substances harmful to the human body in the receiving condition, and discriminates based on a preset degree of conformance to the condition in accordance with the difference amount. The discrimination result is displayed on the output unit 13 of each first communication terminal 10 in step S107, and on the output unit 23 of each second communication terminal 20 in step S108. Therefore, the first transactor 100 and the second transactor 200 can refer to the degree of conformance to the condition of the emission reduction amount of substances harmful to the human body when selecting a trading partner.

[0055] According to the present embodiment described above, even if the environmental value is a different type from that in the first embodiment, the environmental value trading system 1 can be used to match companies or organizations that wish to transfer environmental value with companies or organizations that wish to receive environmental value, thereby promoting transactions. This makes it possible to stimulate environmental value trading and promote environmental protection. In particular, this embodiment can promote the reduction of emissions of substances harmful to the human body.

[0056] (Third embodiment) The third embodiment differs from the first embodiment in the type of environmental value 400. The environmental value 400 of this embodiment is the amount of carbon dioxide recovered using direct air capture technology that directly recovers carbon dioxide from the atmosphere.

[0057] Traditionally, carbon dioxide emission rights, carbon dioxide reductions, and net carbon dioxide emissions related to life cycle assessments have been traded as environmental values, but capturing carbon dioxide from the atmosphere using direct air capture technology has not been subject to trading. However, if the captured carbon dioxide is stored or converted into a valuable resource, it will result in a reduction of greenhouse gas emissions.

[0058] Therefore, in this embodiment, the amount of carbon dioxide captured using direct air capture technology is used as the environmental value. The amount of carbon dioxide captured, i.e., the amount of environmental value 400 in this embodiment, is guaranteed by certification 600 by certifier 300, just like in the first embodiment.

[0059] The configuration of the environmental value trading system used in this embodiment is the same as that of the environmental value trading system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the environmental value trading system according to this embodiment will be described, focusing on the differences from the first embodiment.

[0060] In this embodiment, in step S101 shown in Figure 3, when a plurality of first transactors 100 operate the input unit 11 of their own first communication terminal 10 to input the conditions for transferring the environmental value, they input the amount of carbon dioxide recovered using direct air capture technology as the amount of environmental value to be transferred. Also, in step S102, when a plurality of second transactors 200 operate the input unit 21 of their own second communication terminal 20 to input the conditions for receiving the environmental value, they input the amount of carbon dioxide recovered using direct air capture technology as the amount of environmental value to be received.

[0061] The amount of carbon dioxide recovered input in step S101 is received by the communication unit 31 of the server device 30 together with other delivery conditions in step S103 and stored in the memory unit 33. Meanwhile, the amount of carbon dioxide recovered input in step S102 is also received by the communication unit 31 of the server device 30 together with other receiving conditions in step S103 and stored in the memory unit 33.

[0062] Fig. 8 is a diagram showing an example of a database stored in the storage unit 33 according to the third embodiment. The first database 331b shown in Fig. 8 stores the amount of carbon dioxide captured using direct air capture technology as one of the conditions for transferring environmental value. Meanwhile, the second database 332b also stores the amount of carbon dioxide captured using direct air capture technology as one of the conditions for receiving environmental value.

[0063] Then, in step S105, the discrimination unit 32 calculates the difference between the amount of carbon dioxide recovered in the delivery condition and the amount of carbon dioxide recovered in the receiving condition, and discriminates based on the degree of conformance to the conditions set in advance according to the difference. The discrimination result is displayed on the output unit 13 of each first communication terminal 10 in step S107, and on the output unit 23 of each second communication terminal 20 in step S108. Therefore, the first transactor 100 and the second transactor 200 can refer to the degree of conformance to the conditions for the amount of carbon dioxide recovered using direct air capture technology when selecting a trading partner.

[0064] According to the present embodiment described above, even if the environmental value is a different type from that in the first embodiment, the environmental value trading system 1 can be used to match companies or organizations that wish to transfer environmental value with companies or organizations that wish to receive environmental value, thereby promoting transactions. This makes it possible to stimulate environmental value trading and promote environmental protection. In particular, this embodiment can promote the capture of carbon dioxide using direct air capture technology.

[0065] (Fourth embodiment) The fourth embodiment differs from the first embodiment in the type of environmental value 400. The environmental value 400 of this embodiment is the reduction in the amount of waste resin derived from fossil raw materials.

[0066] Examples of fossil-derived resins include plastic, vinyl, and nylon. Many fossil-derived resins generate carbon dioxide when disposed of. Furthermore, if they contain chlorine atoms, they are likely to generate dioxins. Therefore, reducing the amount of fossil-derived resin disposed of is desirable from an environmental perspective. Measures to reduce the amount of waste, i.e., measures to create environmental value 400, include not only reducing the amount of fossil-derived resin used and extending its life, but also reducing the number of plastic bags distributed at stores. The amount of waste reduction of fossil-derived resin, i.e., the amount of environmental value 400 in this embodiment, is guaranteed by certification 600 by certifier 300, as in the first embodiment.

[0067] The configuration of the environmental value trading system used in this embodiment is the same as that of the environmental value trading system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the environmental value trading 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 3, when a plurality of first transactors 100 operate the input unit 11 of their own first communication terminal 10 to input the conditions for transferring the environmental value, they input the amount of waste reduction of resin derived from fossil raw materials as the amount of environmental value to be transferred. Also, in step S102, when a plurality of second transactors 200 operate the input unit 21 of their own second communication terminal 20 to input the conditions for receiving the environmental value, they input the amount of waste reduction of resin derived from fossil raw materials as the amount of environmental value to be received.

[0069] The waste reduction amount of fossil raw material derived resin input in step S101 is received by the communication unit 31 of the server device 30 together with other delivery conditions in step S103 and stored in the memory unit 33. Meanwhile, the waste reduction amount of fossil raw material derived resin input in step S102 is also received by the communication unit 31 of the server device 30 together with other receiving conditions in step S103 and stored in the memory unit 33.

[0070] Fig. 9 is a diagram showing an example of a database stored in the storage unit 33 according to the fourth embodiment. The first database 331c shown in Fig. 9 stores the amount of waste reduction of resin derived from fossil raw materials as one of the conditions for transferring environmental value. Meanwhile, the second database 332c also stores the amount of waste reduction of resin derived from fossil raw materials as one of the conditions for receiving environmental value.

[0071] Then, in step S105, the discrimination unit 32 calculates the difference between the amount of waste reduction of fossil raw material-derived resin in the delivery condition and the amount of waste reduction of fossil raw material-derived resin in the receipt condition, and discriminates based on the degree of conformance to the condition set in advance according to the amount of difference. The discrimination result is displayed on the output unit 13 of each first communication terminal 10 in step S107, and on the output unit 23 of each second communication terminal 20 in step S108. Therefore, the first transactor 100 and the second transactor 200 can refer to the degree of conformance to the condition of the amount of waste reduction of fossil raw material-derived resin when selecting a trading partner.

[0072] According to the present embodiment described above, even if the environmental value is a different type from that in the first embodiment, the environmental value trading system 1 can be used to match companies or organizations that wish to transfer environmental value with companies or organizations that wish to receive environmental value, thereby facilitating transactions. This makes it possible to stimulate environmental value trading and promote environmental protection. In particular, this embodiment can promote the reduction of waste volumes of resins derived from fossil raw materials.

[0073] (Fifth embodiment) The fifth embodiment differs from the first embodiment in the type of environmental value 400. The environmental value 400 of this embodiment is the amount of plant-derived resin or biodegradable plastic introduced.

[0074] An example of a plant-derived resin is cellulose nanofiber. Plant-derived resins are carbon-neutral because they are produced from plants that fix carbon dioxide. Therefore, by introducing plant-derived resins, the amount of fossil-derived resins used can be reduced. As a result, the amount of fossil-derived resins discarded can be reduced, thereby reducing the amount of carbon dioxide emitted and the net amount of carbon dioxide emitted.

[0075] Biodegradable plastics are plastics that are eventually broken down into water and carbon dioxide by microorganisms in nature. Disposing of biodegradable plastics does not reduce carbon dioxide emissions, but it does help solve the problem of marine litter, where plastic bags and microplastics floating in seawater have a negative impact on the ecosystem. Biodegradable plastics also do not produce dioxins.

[0076] Therefore, in this embodiment, the amount of plant-derived resin or biodegradable plastic introduced is traded as environmental value 400. The amount of plant-derived resin or biodegradable plastic introduced, i.e., the amount of environmental value 400 in this embodiment, is guaranteed by certification 600 by certifier 300, as in the first embodiment.

[0077] The configuration of the environmental value trading system used in this embodiment is the same as that of the environmental value trading system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the environmental value trading system according to this embodiment will be described, focusing on the differences from the first embodiment.

[0078] In this embodiment, in step S101 shown in Figure 3, when a plurality of first transactors 100 operate the input unit 11 of their own first communication terminal 10 to input the conditions for transferring the environmental value, they input the amount of plant-derived resin or biodegradable plastic to be introduced as the amount of environmental value to be transferred. Also, in step S102, when a plurality of second transactors 200 operate the input unit 21 of their own second communication terminal 20 to input the conditions for receiving the environmental value, they input the amount of plant-derived resin or biodegradable plastic to be introduced as the amount of environmental value to be received.

[0079] The introduction amount of plant-derived resin or biodegradable plastic input in step S101 is received by the communication unit 31 of the server device 30 together with other delivery conditions in step S103 and stored in the memory unit 33. Meanwhile, the introduction amount of plant-derived resin or biodegradable plastic input in step S102 is also received by the communication unit 31 of the server device 30 together with other receiving conditions in step S103 and stored in the memory unit 33.

[0080] Fig. 10 is a diagram showing an example of a database stored in the storage unit 33 according to the fifth embodiment. The first database 331d shown in Fig. 10 stores the amount of plant-derived resin or biodegradable plastic introduced as one of the conditions for transferring environmental value. Meanwhile, the second database 332d also stores the amount of plant-derived resin or biodegradable plastic introduced as one of the conditions for receiving environmental value.

[0081] Then, in step S105, the discrimination unit 32 calculates the difference between the amount of plant-derived resin or biodegradable plastic introduced as the delivery condition and the amount of plant-derived resin or biodegradable plastic introduced as the receiving condition, and discriminates based on a preset degree of conformance to the condition according to the difference. The discrimination result is displayed on the output unit 13 of each first communication terminal 10 in step S107, and on the output unit 23 of each second communication terminal 20 in step S108. Therefore, the first transactor 100 and the second transactor 200 can refer to the degree of conformance to the condition of the amount of plant-derived resin or biodegradable plastic introduced when selecting a trading partner.

[0082] According to the present embodiment described above, even if the environmental value is a different type from that in the first embodiment, the environmental value trading system 1 can be used to connect companies or organizations that wish to transfer environmental value with companies or organizations that wish to receive environmental value, thereby facilitating transactions. This makes it possible to stimulate environmental value trading and promote environmental protection. In particular, this embodiment can promote an increase in the amount of plant-derived resins or biodegradable plastics introduced.

[0083] (Sixth embodiment) The sixth embodiment differs from the first embodiment in the type of environmental value 400. The environmental value 400 of this embodiment is the amount of use of a product that has been certified by the certifier 300 as having a sufficiently small adverse impact on the environment during production.

[0084] Products that have a small adverse impact on the environment during manufacturing include, for example, products that consume less power during manufacturing and have a small actual carbon dioxide emissions, or products that generate less waste offcuts and wastewater during manufacturing, and have a small environmental impact during manufacturing. When there is less waste derived from fossil-derived raw materials, less carbon dioxide is generated during waste disposal. Furthermore, when there is less waste and wastewater, less power is consumed during waste (wastewater) treatment, and therefore less actual carbon dioxide emissions. In this way, by selecting and using products that have a small environmental impact during manufacturing that are certified by the certifier 300, it is possible to indirectly reduce actual carbon dioxide emissions.

[0085] Therefore, in this embodiment, the amount of usage of certified products that have been certified by the certifier 300 and have a low environmental impact during production is traded as environmental value 400. The amount of usage of these certified products, that is, the amount of environmental value 400 in this embodiment, is also guaranteed by the certification 600 of the certifier 300.

[0086] The configuration of the environmental value trading system used in this embodiment is the same as that of the environmental value trading system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the environmental value trading system according to this embodiment will be described, focusing on the differences from the first embodiment.

[0087] In this embodiment, in step S101 shown in Figure 3, when a plurality of first transactors 100 operate the input unit 11 of their own first communication terminal 10 to input the conditions for transferring the environmental value, they input the amount of usage of certified products with a small environmental impact during production as the amount of environmental value to be transferred. Also, in step S102, when a plurality of second transactors 200 operate the input unit 21 of their own second communication terminal 20 to input the conditions for receiving the environmental value, they input the amount of usage of certified products with a small environmental impact during production as the amount of environmental value to be received.

[0088] The usage amount of the certified product input in step S101 is received by the communication unit 31 of the server device 30 together with other delivery conditions in step S103 and stored in the memory unit 33. Meanwhile, the usage amount of the certified product input in step S102 is also received by the communication unit 31 of the server device 30 together with other receiving conditions in step S103 and stored in the memory unit 33.

[0089] Fig. 11 is a diagram showing an example of a database stored in the storage unit 33 according to the sixth embodiment. The first database 331e shown in Fig. 11 stores the amount of usage of certified products with low environmental impact during production as one of the conditions for transferring the environmental value. Meanwhile, the second database 332e also stores the amount of usage of certified products with low environmental impact during production as one of the conditions for receiving the environmental value.

[0090] Then, in step S105, the discrimination unit 32 calculates the difference between the amount of certified product used in the delivery condition and the amount of certified product used in the receipt condition, and discriminates based on a preset degree of conformance to the condition according to the amount of difference. The discrimination result is displayed on the output unit 13 of each first communication terminal 10 in step S107, and on the output unit 23 of each second communication terminal 20 in step S108. Therefore, when selecting a trading partner, the first transactor 100 and the second transactor 200 can refer to the degree of conformance to the condition of the amount of certified product used, which has a small environmental impact during production.

[0091] According to the present embodiment described above, even if the environmental value is a different type from that in the first embodiment, the environmental value trading system 1 can be used to match companies or organizations that wish to transfer environmental value with companies or organizations that wish to receive environmental value, thereby promoting transactions. This makes it possible to stimulate environmental value trading and promote environmental protection. In particular, this embodiment can promote the use of products that have a small environmental impact during manufacturing, thereby reducing the environmental impact.

[0092] (Seventh embodiment) The seventh embodiment differs from the first embodiment in the type of environmental value 400. The environmental value 400 in this embodiment is the amount of use of a product that has been certified by the certifier 300 as having a sufficiently small adverse effect on the environment during transportation from the manufacturing site to the sales site.

[0093] Products that have a small adverse effect on the environment during transportation include products that have a small environmental impact during transportation, such as products transported using a vehicle that uses carbon-neutral biodiesel fuel or an electric vehicle that is charged with electricity generated using renewable energy. In this way, by selecting and using products that have a small environmental impact during transportation that are certified by the certifier 300, it is possible to indirectly reduce the actual amount of carbon dioxide emissions.

[0094] Therefore, in this embodiment, the amount of usage of a certified product that has been certified by the certifier 300 and has a small environmental impact during transportation is traded as environmental value 400. The amount of usage of this certified product, that is, the amount of environmental value 400 in this embodiment, is also guaranteed by the certification 600 of the certifier 300.

[0095] The configuration of the environmental value trading system used in this embodiment is the same as that of the environmental value trading system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the environmental value trading system according to this embodiment will be described, focusing on the differences from the first embodiment.

[0096] In this embodiment, in step S101 shown in Figure 3, when a plurality of first transactors 100 operate the input unit 11 of their own first communication terminal 10 to input the conditions for transferring the environmental value, they input the amount of usage of a certified product that has a small environmental impact during transportation as the amount of environmental value to be transferred. Also, in step S102, when a plurality of second transactors 200 operate the input unit 21 of their own second communication terminal 20 to input the conditions for receiving the environmental value, they input the amount of usage of a certified product that has a small environmental impact during transportation as the amount of environmental value to be received.

[0097] The usage amount of the certified product input in step S101 is received by the communication unit 31 of the server device 30 together with other delivery conditions in step S103 and stored in the memory unit 33. Meanwhile, the usage amount of the certified product input in step S102 is also received by the communication unit 31 of the server device 30 together with other receiving conditions in step S103 and stored in the memory unit 33.

[0098] Fig. 12 is a diagram showing an example of a database stored in the storage unit 33 according to the seventh embodiment. The first database 331f shown in Fig. 12 stores the amount of usage of certified products that have a low environmental impact during transportation as one of the conditions for transferring the environmental value. Meanwhile, the second database 332f also stores the amount of usage of certified products that have a low environmental impact during transportation as one of the conditions for receiving the environmental value.

[0099] Then, in step S105, the discrimination unit 32 calculates the difference between the amount of certified product used in the delivery condition and the amount of certified product used in the receipt condition, and discriminates based on a preset degree of conformance to the condition according to the amount of difference. The discrimination result is displayed on the output unit 13 of each first communication terminal 10 in step S107, and on the output unit 23 of each second communication terminal 20 in step S108. Therefore, when selecting a trading partner, the first transactor 100 and the second transactor 200 can refer to the degree of conformance to the condition of the amount of certified product used, which has a small environmental impact during transportation.

[0100] According to the present embodiment described above, even if the environmental value is a different type from that in the first embodiment, the environmental value trading system 1 can be used to match companies or organizations that wish to transfer environmental value with companies or organizations that wish to receive environmental value, thereby promoting transactions. This makes it possible to stimulate environmental value trading and promote environmental protection. In particular, this embodiment can promote the use of products that have a small environmental impact during transportation, thereby indirectly reducing actual carbon dioxide emissions.

[0101] (Eighth embodiment) The eighth embodiment differs from the first embodiment in the type of environmental value 400. The environmental value 400 of this embodiment is the amount of use of a product that has been certified by the certifier 300 as having a sufficiently small adverse effect on the environment when disposed of.

[0102] Products that have a small adverse impact on the environment when discarded include, for example, products that use a small amount of fossil-derived raw materials in the product, its packaging, and the product's packaging, products that are easy to separate by material and are easy to recycle, etc. In this way, by selecting and using products that have a small environmental impact when discarded and are certified by certifier 300, it is possible to indirectly reduce the actual amount of carbon dioxide emissions.

[0103] Therefore, in this embodiment, the amount of usage of certified products that have been certified by the certifier 300 and have a low environmental impact when disposed of is traded as environmental value 400. The amount of materials for these certified products, that is, the amount of environmental value 400 in this embodiment, is also guaranteed by the certification 600 of the certifier 300.

[0104] The configuration of the environmental value trading system used in this embodiment is the same as that of the environmental value trading system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the environmental value trading system according to this embodiment will be described, focusing on the differences from the first embodiment.

[0105] In this embodiment, in step S101 shown in Figure 3, when a plurality of first transactors 100 operate the input unit 11 of their own first communication terminal 10 to input the conditions for transferring the environmental value, they input the amount of usage of a certified product that has a small environmental impact when disposed of as the amount of environmental value to be transferred. Also, in step S102, when a plurality of second transactors 200 operate the input unit 21 of their own second communication terminal 20 to input the conditions for receiving the environmental value, they input the amount of usage of a certified product that has a small environmental impact when disposed of as the amount of environmental value to be received.

[0106] The usage amount of the certified product input in step S101 is received by the communication unit 31 of the server device 30 together with other delivery conditions in step S103 and stored in the memory unit 33. Meanwhile, the usage amount of the certified product input in step S102 is also received by the communication unit 31 of the server device 30 together with other receiving conditions in step S103 and stored in the memory unit 33.

[0107] Fig. 13 is a diagram showing an example of a database stored in the storage unit 33 according to the eighth embodiment. The first database 331g shown in Fig. 13 stores the amount of usage of certified products that have a low environmental impact when disposed of as one of the conditions for transferring environmental value. Meanwhile, the second database 332g also stores the amount of usage of certified products that have a low environmental impact when disposed of as one of the conditions for receiving environmental value.

[0108] Then, in step S105, the discrimination unit 32 calculates the difference between the amount of certified product used in the delivery condition and the amount of certified product used in the receipt condition, and discriminates based on a preset degree of conformance to the condition according to the amount of difference. The discrimination result is displayed on the output unit 13 of each first communication terminal 10 in step S107, and on the output unit 23 of each second communication terminal 20 in step S108. Therefore, when selecting a trading partner, the first transactor 100 and the second transactor 200 can refer to the degree of conformance to the condition of the amount of certified product used, which has a small environmental impact when disposed of.

[0109] According to the present embodiment described above, even if the environmental value is a different type from that in the first embodiment, the environmental value trading system 1 can be used to match companies or organizations that wish to transfer environmental value with companies or organizations that wish to receive environmental value, thereby promoting transactions. This makes it possible to stimulate environmental value trading and promote environmental protection. In particular, this embodiment can promote the use of products that have a small environmental impact when disposed of, thereby indirectly reducing actual carbon dioxide emissions.

[0110] (Ninth embodiment) The ninth embodiment differs from the first embodiment in the type of environmental value 400. The environmental value 400 of this embodiment is the amount of use of products manufactured in factories that are treated as having virtually no carbon dioxide emissions.

[0111] Products manufactured in factories that are treated as having no net carbon dioxide emissions include, for example, products that have been certified by the certifier 300 as having been manufactured in factories that use electricity generated from renewable energy sources through the purchase of a non-fossil certificate. In this way, by purchasing a certificate and selecting and using certified products that have been manufactured in factories that are treated as having no net carbon dioxide emissions, it is possible to indirectly reduce carbon dioxide emissions.

[0112] Therefore, in this embodiment, the amount of use of products manufactured in factories that are certified by the certifier 300 as having virtually no carbon dioxide emissions is traded as environmental value 400. The amount of use of these certified products, that is, the amount of environmental value 400 in this embodiment and carbon traceability, are also guaranteed by the certification 600 of the certifier 300.

[0113] The configuration of the environmental value trading system used in this embodiment is the same as that of the environmental value trading system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the environmental value trading system according to this embodiment will be described, focusing on the differences from the first embodiment.

[0114] In this embodiment, in step S101 shown in Figure 3, when a plurality of first transactors 100 operate the input unit 11 of their own first communication terminal 10 to input the conditions for transferring the environmental value, they input the amount of product usage manufactured in a factory that is treated as having no substantial carbon dioxide emissions as certified by the certifier 300 as the amount of environmental value to be transferred. Also, in step S102, when a plurality of second transactors 200 operate the input unit 21 of their own second communication terminal 20 to input the conditions for receiving the environmental value, they input the amount of product usage manufactured in a factory that is treated as having no substantial carbon dioxide emissions as certified by the certifier 300 as the amount of environmental value to be received.

[0115] The usage amount of the certified product input in step S101 is received by the communication unit 31 of the server device 30 together with other delivery conditions in step S103 and stored in the memory unit 33. Meanwhile, the usage amount of the certified product input in step S102 is also received by the communication unit 31 of the server device 30 together with other receiving conditions in step S103 and stored in the memory unit 33.

[0116] Fig. 14 is a diagram showing an example of a database stored in the storage unit 33 according to the ninth embodiment. The first database 331h shown in Fig. 14 stores the amount of certified products used in factories with virtually no carbon dioxide emissions as one of the conditions for transferring the environmental value. Meanwhile, the second database 332g also stores the amount of certified products used in factories with virtually no carbon dioxide emissions as one of the conditions for receiving the environmental value.

[0117] Then, in step S105, the discrimination unit 32 calculates the difference between the amount of certified product used in the delivery condition and the amount of certified product used in the receipt condition, and discriminates based on a preset degree of conformance to the condition according to the amount of difference. The discrimination result is displayed on the output unit 13 of each first communication terminal 10 in step S107, and on the output unit 23 of each second communication terminal 20 in step S108. Therefore, when selecting a trading partner, the first transactor 100 and the second transactor 200 can refer to the degree of conformance to the condition of the amount of certified product used manufactured in a factory with virtually no carbon dioxide emissions.

[0118] According to the present embodiment described above, even if the environmental value is a different type from that in the first embodiment, it is possible to promote transactions by connecting companies or organizations that want to transfer environmental value with companies or organizations that want to receive environmental value via the environmental value trading system 1. This makes it possible to stimulate environmental value trading and promote environmental protection. In particular, this embodiment can promote the use of products that have been certified as manufactured in factories with virtually no carbon dioxide emissions, thereby indirectly reducing the amount of carbon dioxide emissions.

[0119] (Tenth embodiment) The tenth embodiment differs from the first embodiment in the type of environmental value 400. The environmental value 400 of this embodiment is the production volume of products that have been certified by the certifier 300 as having a sufficiently small adverse impact on the environment.

[0120] Examples of products with a small negative impact on the environment include products that consume less power during user use, leading to reduced carbon dioxide emissions, products that do not use fossil-derived packaging materials, lightweight products that lead to reduced fuel consumption for transport vehicles, and products that are designed to be environmentally friendly, such as being easily separated by material when disposed of and easily recycled. In this embodiment, situations in which the negative impact on the environment is sufficiently small may occur during manufacturing, transportation, use, or disposal, as described above. By selecting and using such certified products, negative impact on the environment can be indirectly reduced.

[0121] Therefore, in this embodiment, the production volume of a product that places a small burden on the environment when used by a user, manufactured, transported, or disposed of is traded as environmental value 400. The production volume of this product, that is, the amount of environmental value 400 in this embodiment, is also guaranteed by authentication 600 by certifier 300.

[0122] The configuration of the environmental value trading system used in this embodiment is the same as that of the environmental value trading system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the environmental value trading system according to this embodiment will be described, focusing on the differences from the first embodiment.

[0123] In this embodiment, in step S101 shown in Figure 3, when multiple first transactors 100 operate the input unit 11 of their own first communication terminal 10 to input the conditions for transferring the environmental value, they input the production volume of certified products that have been certified by authentication 600 to have a low environmental impact when used by the user, manufactured, transported, or disposed of, as the amount of environmental value to be transferred. Also, in step S102, when multiple second transactors 200 operate the input unit 21 of their own second communication terminal 20 to input the conditions for receiving the environmental value, they input the production volume of certified products that have been certified by authentication 600 to have a low environmental impact when used by the user, manufactured, transported, or disposed of, as the amount of environmental value to be received.

[0124] The production volume of the certified products input in step S101 is received by the communication unit 31 of the server device 30 together with other delivery conditions in step S103 and stored in the memory unit 33. Meanwhile, the production volume of the certified products input in step S102 is also received by the communication unit 31 of the server device 30 together with other receiving conditions in step S103 and stored in the memory unit 33.

[0125] Fig. 15 is a diagram showing an example of a database stored in the storage unit 33 according to the tenth embodiment. The first database 331i shown in Fig. 11 stores the production volume of certified products that have a low environmental impact when used, manufactured, transported, or disposed of as one of the conditions for transferring the environmental value. Meanwhile, the second database 332i also stores the production volume of certified products that have a low environmental impact when used, manufactured, transported, or disposed of as one of the conditions for receiving the environmental value.

[0126] Then, in step S105, the discrimination unit 32 calculates the difference between the production volume of certified products under the delivery condition and the production volume of certified products under the receipt condition, and discriminates based on a preset degree of conformance to the condition according to the difference. The discrimination result is displayed on the output unit 13 of each first communication terminal 10 in step S107, and on the output unit 23 of each second communication terminal 20 in step S108. Therefore, when selecting a trading partner, the first transactor 100 and the second transactor 200 can refer to the degree of conformance to the condition of the production volume of certified products that have a small environmental impact during use, production, transportation, or disposal.

[0127] According to the present embodiment described above, even if the environmental value is a different type from that in the first embodiment, the environmental value trading system 1 can be used to connect companies or organizations that wish to transfer environmental value with companies or organizations that wish to receive environmental value, thereby promoting transactions. This makes it possible to stimulate environmental value trading and promote environmental protection. In particular, this embodiment can promote the production of products that have a small environmental impact during use, manufacturing, transportation, or disposal, thereby indirectly reducing adverse effects on the environment.

[0128] (Eleventh embodiment) The eleventh embodiment differs from the first embodiment in the type of environmental value 400. The environmental value 400 of this embodiment is the production volume of recycled certified products that have been certified by the certifier 300 as having been sufficiently recycled.

[0129] Certified recycled products include, for example, products made from recycled plastics and paper recovered from waste, and products made from recycled water, i.e., products that reuse water. By selecting and using such certified recycled products, it is possible to indirectly reduce actual carbon dioxide emissions. In particular, manufacturing certified recycled products using recycled water not only indirectly reduces carbon dioxide emissions by reducing the total amount of electricity consumed by pumps, etc., but also can be a solution to water resource issues.

[0130] Therefore, in this embodiment, the production volume of the above-mentioned recycle certified products is traded as the environmental value 400. The production volume of the recycle certified products, that is, the amount of the environmental value 400 in this embodiment, is also guaranteed by the certification 600 of the certifier 300.

[0131] The configuration of the environmental value trading system used in this embodiment is the same as that of the environmental value trading system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the environmental value trading system according to this embodiment will be described, focusing on the differences from the first embodiment.

[0132] In this embodiment, in step S101 shown in Figure 3, when a plurality of first transactors 100 operate the input unit 11 of their own first communication terminal 10 to input the conditions for transferring the environmental value, they input the production volume of certified recycled products that have been certified by the certifier 300 as having been sufficiently recycled as the amount of environmental value to be transferred. Also, in step S102, when a plurality of second transactors 200 operate the input unit 21 of their own second communication terminal 20 to input the conditions for receiving the environmental value, they input the production volume of certified recycled products that have been certified by the certifier 300 as having been sufficiently recycled as the amount of environmental value to be received.

[0133] The production volume of certified recycled products input in step S101 is received by communication unit 31 of server device 30 together with other delivery conditions in step S103 and stored in memory unit 33. Meanwhile, the production volume of certified recycled products input in step S102 is also received by communication unit 31 of server device 30 together with other receiving conditions in step S103 and stored in memory unit 33.

[0134] Fig. 16 is a diagram showing an example of a database stored in the storage unit 33 according to the eleventh embodiment. The first database 331j shown in Fig. 16 stores the production volume of certified recycled products as one of the conditions for transferring environmental value. Meanwhile, the second database 332j also stores the production volume of certified recycled products as one of the conditions for receiving environmental value.

[0135] Then, in step S105, the discrimination unit 32 calculates the difference between the production volume of certified recycled products in the delivery condition and the production volume of certified recycled products in the receipt condition, and discriminates based on the degree of conformance to the condition set in advance according to the difference. The discrimination result is displayed on the output unit 13 of each first communication terminal 10 in step S107, and on the output unit 23 of each second communication terminal 20 in step S108. Therefore, the first transactor 100 and the second transactor 200 can refer to the degree of conformance to the condition of the production volume of certified recycled products when selecting a trading partner.

[0136] According to the present embodiment described above, even if the environmental value is a different type from that in the first embodiment, the environmental value trading system 1 can be used to connect companies and organizations that want to transfer environmental value with companies and organizations that want to receive environmental value, thereby facilitating transactions. This makes it possible to stimulate environmental value trading and promote environmental protection. In particular, this embodiment can promote the production of recycled products, thereby indirectly reducing actual carbon dioxide emissions.

[0137] (Twelfth embodiment) The twelfth embodiment differs from the first embodiment in the type of environmental value 400. The environmental value 400 of this embodiment is the performance of an action to reduce the discharge of substances harmful to the environment or human body.

[0138] Examples of actions to reduce emissions of substances harmful to the environment or human body include environmentally friendly product design that does not use substances harmful to the environment or human body, reducing the amount of plastic bag waste, and reducing carbon dioxide emissions by using electricity generated from renewable energy.Furthermore, the appropriate use of agricultural fertilizers also falls under this category, as excessive use of agricultural fertilizers can release nitrous oxide, a greenhouse gas.

[0139] The performance of the above actions is certified by the certifier 300. Furthermore, the amount of environmental value 400 is quantified in advance according to the performance of each action. The degree of achievement, which indicates the extent to which the actions to reduce emissions of substances harmful to the environment or human body have been achieved, i.e., the amount of environmental value 400, is also guaranteed by the certification 600 of the certifier 300.

[0140] Furthermore, in this embodiment, the consideration 500 for the environmental value 400 may not only be money or goods, but also another environmental value. For example, when the first transactor 100 attempts to offset carbon emissions by purchasing a non-fossil fuel certificate, the first transactor 100 can reduce the purchase price of the non-fossil fuel certificate by receiving the non-fossil fuel certificate as consideration 500 for delivering the environmental value 400 to the second transactor 200. Furthermore, because the above-mentioned actions themselves have value, simply being certified or possessing the environmental value 400 in this embodiment can improve the image of a company or organization. Furthermore, this raises awareness of environmental protection among members of companies and organizations, further promoting activities that lead to environmental protection.

[0141] The configuration of the environmental value trading system used in this embodiment is the same as that of the environmental value trading system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the environmental value trading system according to this embodiment will be described, focusing on the differences from the first embodiment.

[0142] In this embodiment, in step S101 shown in Figure 3, when multiple first transactors 100 operate the input unit 11 of their own first communication terminal 10 to input the conditions for transferring the environmental value, they input a numerical value determined according to the degree of achievement of the action of reducing the emission of hazardous substances that are harmful to the environment or human body as the amount of the environmental value to be transferred. Also, in step S102, when multiple second transactors 200 operate the input unit 21 of their own second communication terminal 20 to input the conditions for receiving the environmental value, they input a numerical value determined according to the degree of achievement of the action of reducing the emission of hazardous substances that are harmful to the environment or human body as the amount of the environmental value to be received.

[0143] The numerical value indicating the degree of achievement of the action to reduce the emission of hazardous substances input in step S101 is received by the communication unit 31 of the server device 30 together with other delivery conditions in step S103 and stored in the memory unit 33. Meanwhile, the numerical value indicating the degree of achievement of the action to reduce the emission of hazardous substances input in step S102 is also received by the communication unit 31 of the server device 30 together with other receiving conditions in step S103 and stored in the memory unit 33.

[0144] Fig. 17 is a diagram showing an example of a database stored in the storage unit 33 according to the twelfth embodiment. A first database 331k shown in Fig. 17 stores a numerical value indicating the degree of achievement of actions to reduce hazardous substance emissions as one of the conditions for transferring an environmental value. Meanwhile, a second database 332k also stores a numerical value indicating the degree of achievement of actions to reduce hazardous substance emissions as one of the conditions for receiving an environmental value.

[0145] Then, in step S105, the discrimination unit 32 calculates the difference between the numerical value of the delivery condition and the numerical value of the receipt condition, and discriminates based on a preset degree of condition conformance according to the amount of difference. The discrimination result is displayed on the output unit 13 of each first communication terminal 10 in step S107, and on the output unit 23 of each second communication terminal 20 in step S108. Therefore, the first transactor 100 and the second transactor 200 can refer to the degree of condition conformance of the degree of achievement of actions to reduce emissions of hazardous substances when selecting a trading partner.

[0146] According to the present embodiment described above, even if the environmental value is a different type from that in the first embodiment, the environmental value trading system 1 can be used to match companies or organizations that wish to transfer environmental value with companies or organizations that wish to receive environmental value, thereby promoting transactions. This makes it possible to stimulate environmental value trading and promote environmental protection. In particular, in this embodiment, environmental protection can be further promoted by treating efforts to reduce emissions of harmful substances as environmental value 400.

[0147] (Thirteenth embodiment) The thirteenth embodiment differs from the first embodiment in the type of environmental value 400. The environmental value 400 of this embodiment is the performance of an action that reduces the actual amount of carbon dioxide emissions.

[0148] Examples of actions that reduce net carbon dioxide emissions include using electricity generated using renewable energy or biofuels, and carbon offsetting through carbon trading. Carbon trading includes purchasing electricity that is said to have been generated using renewable energy and forest conservation. Because plants can fix carbon dioxide, forest conservation can be considered as absorbing carbon dioxide.

[0149] The performance of the above actions is certified by the certifier 300. Furthermore, the amount of environmental value 400 is quantified in advance according to the performance of each action. The degree of achievement, which indicates the extent to which the actions to reduce actual carbon dioxide emissions have been achieved, i.e., the amount of environmental value 400, is also guaranteed by the certification 600 of the certifier 300.

[0150] Furthermore, in this embodiment, the compensation 500 for the environmental value 400 may be not only money or goods, but also another environmental value. Because the above-mentioned actions themselves have value, the environmental value 400 in this embodiment can improve the image of a company or organization simply by being certified or possessing it. Furthermore, it will raise awareness of environmental protection among members of the company or organization, further promoting activities that lead to environmental protection.

[0151] The configuration of the environmental value trading system used in this embodiment is the same as that of the environmental value trading system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the environmental value trading system according to this embodiment will be described, focusing on the differences from the first embodiment.

[0152] In this embodiment, in step S101 shown in Figure 3, when a plurality of first transactors 100 operate the input unit 11 of their own first communication terminal 10 to input the conditions for transferring the environmental value, they input a numerical value determined according to the degree of achievement of the action to reduce real carbon dioxide emissions as the amount of the environmental value to be transferred. Also, in step S102, when a plurality of second transactors 200 operate the input unit 21 of their own second communication terminal 20 to input the conditions for receiving the environmental value, they input a numerical value determined according to the degree of achievement of the action to reduce real carbon dioxide emissions as the amount of the environmental value to be received.

[0153] The numerical value indicating the degree of achievement of the actual carbon dioxide emission reduction action input in step S101 is received by the communication unit 31 of the server device 30 together with other delivery conditions in step S103 and stored in the memory unit 33. Meanwhile, the numerical value indicating the degree of achievement of the actual carbon dioxide emission reduction action input in step S102 is also received by the communication unit 31 of the server device 30 together with other receiving conditions in step S103 and stored in the memory unit 33.

[0154] Fig. 18 is a diagram showing an example of a database stored in the storage unit 33 according to the thirteenth embodiment. A first database 331l shown in Fig. 18 stores a numerical value indicating the degree of achievement of a net carbon dioxide emission reduction action as one of the conditions for transferring an environmental value. Meanwhile, a second database 332l also stores a numerical value indicating the degree of achievement of a net carbon dioxide emission reduction action as one of the conditions for receiving an environmental value.

[0155] Then, in step S105, the discrimination unit 32 calculates the difference between the numerical value of the delivery condition and the numerical value of the receiving condition, and discriminates based on the degree of condition conformance set in advance according to the amount of difference. The discrimination result is displayed on the output unit 13 of each first communication terminal 10 in step S107, and on the output unit 23 of each second communication terminal 20 in step S108. Therefore, the first transactor 100 and the second transactor 200 can refer to the degree of condition conformance of the degree of achievement of the actual carbon dioxide emission reduction action when selecting a trading partner.

[0156] According to the present embodiment described above, even if the environmental value is a different type from that in the first embodiment, the environmental value trading system 1 can be used to match companies or organizations that wish to transfer environmental value with companies or organizations that wish to receive environmental value, thereby promoting transactions. This makes it possible to stimulate environmental value trading and promote environmental protection. In particular, in this embodiment, environmental protection can be further promoted by treating efforts to reduce net carbon dioxide emissions as environmental value 400.

[0157] (Fourteenth embodiment) The fourteenth embodiment differs from the first embodiment in the type of environmental value 400. The environmental value 400 of this embodiment is the performance of an action to reduce the amount of waste resin derived from fossil raw materials.

[0158] When fossil-derived resins are disposed of, they often produce carbon dioxide. Furthermore, if they contain chlorine atoms, they are likely to produce dioxins. Therefore, it is desirable to reduce the amount of fossil-derived resins disposed of. Actions to reduce this amount include not only reducing the amount of fossil-derived resin used and extending its lifespan, but also reducing the number of plastic bags distributed at stores.

[0159] The performance of the above actions is certified by the certifier 300. Furthermore, the amount of environmental value 400 is quantified in advance according to the performance of each action. The degree of achievement, which indicates the extent to which the actions to reduce the amount of waste resin derived from fossil raw materials have been achieved, i.e., the amount of environmental value 400, is also guaranteed by the certification 600 of the certifier 300.

[0160] Furthermore, in this embodiment, the compensation 500 for the environmental value 400 may be not only money or goods, but also another environmental value. Because the above-mentioned actions themselves have value, the environmental value 400 in this embodiment can improve the image of a company or organization simply by being certified or possessing it. Furthermore, it will raise awareness of environmental protection among members of the company or organization, further promoting activities that lead to environmental protection.

[0161] The configuration of the environmental value trading system used in this embodiment is the same as that of the environmental value trading system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the environmental value trading system according to this embodiment will be described, focusing on the differences from the first embodiment.

[0162] In this embodiment, in step S101 shown in Figure 3, when multiple first transactors 100 operate the input unit 11 of their own first communication terminal 10 to input the conditions for transferring the environmental value, they input a numerical value determined according to the degree of achievement of the action of reducing the amount of resin derived from fossil raw materials as the amount of environmental value to be transferred. Also, in step S102, when multiple second transactors 200 operate the input unit 21 of their own second communication terminal 20 to input the conditions for receiving the environmental value, they input a numerical value determined according to the degree of achievement of the action of reducing the amount of resin derived from fossil raw materials as the amount of environmental value to be received.

[0163] The numerical value indicating the degree of achievement of the action to reduce waste of fossil raw materials, which was input in step S101, is received by the communication unit 31 of the server device 30 together with other delivery conditions in step S103, and stored in the memory unit 33. Meanwhile, the numerical value indicating the degree of achievement of the action to reduce waste of fossil raw materials, which was input in step S102, is also received by the communication unit 31 of the server device 30 together with other receiving conditions in step S103, and stored in the memory unit 33.

[0164] Fig. 19 is a diagram showing an example of a database stored in the storage unit 33 according to the fourteenth embodiment. A first database 331m shown in Fig. 19 stores a numerical value indicating the degree of achievement of actions to reduce waste of resin derived from fossil raw materials as one of the conditions for transferring environmental value. Meanwhile, a second database 332i also stores a numerical value indicating the degree of achievement of actions to reduce waste of resin derived from fossil raw materials as one of the conditions for receiving environmental value.

[0165] Then, in step S105, the discrimination unit 32 calculates the difference between the numerical value of the delivery condition and the numerical value of the receiving condition, and discriminates based on the degree of conformance of the condition set in advance according to the amount of difference. The discrimination result is displayed on the output unit 13 of each first communication terminal 10 in step S107, and on the output unit 23 of each second communication terminal 20 in step S108. Therefore, the first transactor 100 and the second transactor 200 can refer to the degree of conformance of the condition regarding the achievement of actions to reduce waste of fossil-derived resin when selecting a trading partner.

[0166] According to the present embodiment described above, even if the environmental value is a different type from that in the first embodiment, the environmental value trading system 1 can be used to match companies or organizations that wish to transfer environmental value with companies or organizations that wish to receive environmental value, thereby facilitating transactions. This makes it possible to stimulate environmental value trading and promote environmental protection. In particular, in this embodiment, environmental protection can be further promoted by treating efforts to reduce waste from resins derived from fossil raw materials as environmental value 400.

[0167] (Fifteenth embodiment) The fifteenth embodiment differs from the first embodiment in the type of environmental value 400. The environmental value 400 of this embodiment is the performance of a recycling behavior.

[0168] Examples of recycling behavior include collecting plastic waste and waste paper, manufacturing or selling recycled products, reusing water, and turning waste cooking oil into fuel.

[0169] The performance of the above-mentioned recycling behaviors is certified by the certifier 300. Furthermore, the amount of environmental value 400 is quantified in advance according to the performance of each recycling behavior. The degree of achievement, which indicates the extent to which the recycling behavior has been achieved, i.e., the amount of environmental value 400, is also guaranteed by the certification 600 of the certifier 300.

[0170] Furthermore, in this embodiment, the compensation 500 for the environmental value 400 may be not only money or goods, but also another environmental value. Because the above-mentioned actions themselves have value, the environmental value 400 in this embodiment can improve the image of a company or organization simply by being certified or possessing it. Furthermore, it will raise awareness of environmental protection among members of the company or organization, further promoting activities that lead to environmental protection.

[0171] The configuration of the environmental value trading system used in this embodiment is the same as that of the environmental value trading system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the environmental value trading system according to this embodiment will be described, focusing on the differences from the first embodiment.

[0172] In this embodiment, in step S101 shown in Fig. 3, when a plurality of first transactors 100 operate the input unit 11 of their own first communication terminal 10 to input the conditions for transferring the environmental value, they input a numerical value determined according to the degree of achievement of the recycling action as the amount of the environmental value to be transferred. Also, in step S102, when a plurality of second transactors 200 operate the input unit 21 of their own second communication terminal 20 to input the conditions for receiving the environmental value, they input a numerical value determined according to the degree of achievement of the recycling action as the amount of the environmental value to be received.

[0173] The numerical value indicating the degree of achievement of the recycling action input in step S101 is received by communication unit 31 of server device 30 together with other delivery conditions in step S103 and stored in memory unit 33. Meanwhile, the numerical value indicating the degree of achievement of the recycling action input in step S102 is also received by communication unit 31 of server device 30 together with other receiving conditions in step S103 and stored in memory unit 33.

[0174] Fig. 20 is a diagram showing an example of a database stored in the storage unit 33 according to the fifteenth embodiment. A first database 331n shown in Fig. 20 stores a numerical value indicating the degree of achievement of a recycling action as one of the conditions for transferring an environmental value. Meanwhile, a second database 332n also stores a numerical value indicating the degree of achievement of a recycling action as one of the conditions for receiving an environmental value.

[0175] Then, in step S105, the discrimination unit 32 calculates the difference between the numerical value of the delivery condition and the numerical value of the receiving condition, and discriminates based on a preset condition conformance level according to the difference amount. The discrimination result is displayed on the output unit 13 of each first communication terminal 10 in step S107, and on the output unit 23 of each second communication terminal 20 in step S108. Therefore, the first transactor 100 and the second transactor 200 can refer to the condition conformance level of the achievement level of the recycling behavior when selecting a trading partner.

[0176] According to the present embodiment described above, even if the environmental value is a different type from that in the first embodiment, the environmental value trading system 1 can be used to match companies or organizations that wish to transfer environmental value with companies or organizations that wish to receive environmental value, thereby promoting transactions. This makes it possible to stimulate environmental value trading and promote environmental protection. In particular, in this embodiment, environmental protection can be further promoted by treating recycling behavioral efforts as environmental value 400.

[0177] (16th embodiment) In the sixteenth embodiment, the type of environmental value 400 is different from that in the first embodiment. The environmental value 400 in this embodiment is the performance of research and development activities that lead to environmental protection. Research and development activities that lead to environmental protection include, for example, research and development activities related to non-fossil raw materials, recycling, renewable energy, carbon dioxide capture and storage, and forest protection.

[0178] The execution of the above-mentioned research and development activities is certified by the certifier 300. Furthermore, the amount of environmental value 400 is quantified in advance according to the execution content of each research and development activity. The amount of environmental value 400, i.e., points that comprehensively quantify the degree of achievement that indicates the extent to which the research and development activity has been achieved and the degree of effort that indicates the amount of effort, is also guaranteed by the certification 600 of the certifier 300. Note that the degree of effort is calculated by converting, for example, the time spent on the research and development activity into points.

[0179] Furthermore, in this embodiment, the compensation 500 for the environmental value 400 may be not only money or goods, but also another environmental value. Because the above-mentioned actions themselves have value, the environmental value 400 in this embodiment can improve the image of a company or organization simply by being certified or possessing it. Furthermore, it will raise awareness of environmental protection among members of the company or organization, further promoting activities that lead to environmental protection.

[0180] The configuration of the environmental value trading system used in this embodiment is the same as that of the environmental value trading system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the environmental value trading system according to this embodiment will be described, focusing on the differences from the first embodiment.

[0181] 3, when a plurality of first transactors 100 operate the input unit 11 of their own first communication terminal 10 to input the conditions for transferring the environmental value, they input a numerical value determined according to the points of research and development activities that lead to environmental protection as the amount of the environmental value to be transferred. Also, in step S102, when a plurality of second transactors 200 operate the input unit 21 of their own second communication terminal 20 to input the conditions for receiving the environmental value, they input a numerical value determined according to the points of research and development activities that lead to environmental protection as the amount of the environmental value to be received.

[0182] The numerical value indicating the points for the research and development activities that lead to environmental protection, which was input in step S101, is received by the communication unit 31 of the server device 30 together with other delivery conditions in step S103 and stored in the memory unit 33. Meanwhile, the numerical value indicating the points for the research and development activities that lead to environmental protection, which was input in step S102, is also received by the communication unit 31 of the server device 30 together with other receiving conditions in step S103 and stored in the memory unit 33.

[0183] Fig. 21 is a diagram showing an example of a database stored in the storage unit 33 according to the sixteenth embodiment. A first database 331p shown in Fig. 21 stores a numerical value indicating points for research and development activities that lead to environmental protection as one of the conditions for transferring environmental value. Meanwhile, a second database 332p also stores a numerical value indicating points for research and development activities that lead to environmental protection as one of the conditions for receiving environmental value.

[0184] Then, in step S105, the discrimination unit 32 calculates the difference between the numerical value of the delivery condition and the numerical value of the receipt condition, and discriminates based on a preset degree of condition conformance according to the amount of difference. The discrimination result is displayed on the output unit 13 of each first communication terminal 10 in step S107, and on the output unit 23 of each second communication terminal 20 in step S108. Therefore, the first transactor 100 and the second transactor 200 can refer to the degree of condition conformance of points for research and development activities that lead to environmental protection when selecting a trading partner.

[0185] According to the present embodiment described above, even if the environmental value is a different type from that in the first embodiment, the environmental value trading system 1 can be used to match companies or organizations that wish to transfer environmental value with companies or organizations that wish to receive environmental value, thereby promoting transactions. This makes it possible to stimulate environmental value trading and promote environmental protection. In particular, in this embodiment, environmental protection can be further promoted by treating research and development activities that lead to environmental protection as environmental value 400.

[0186] (17th embodiment) The seventeenth embodiment differs from the first embodiment in the type of environmental value 400. The environmental value 400 of this embodiment is the performance of an environmental protection activity or an environmental awareness activity.

[0187] Environmental protection activities include, for example, picking up trash on the beach and greening activities such as tree planting, which also helps to sequester carbon dioxide. On the other hand, environmental awareness activities include, for example, educating people about the importance of reducing greenhouse gases.

[0188] The performance of the above-mentioned environmental protection activities or environmental awareness activities is certified by the certifier 300. Furthermore, the amount of environmental value 400 is quantified in advance according to the content of the performance of each activity. The amount of environmental value 400, i.e., points that comprehensively quantify the degree of achievement, which indicates the extent to which each activity has been achieved, and the degree of effort, which indicates the amount of effort, is also guaranteed by the certification 600 of the certifier 300. Note that the degree of effort is calculated by converting, for example, the time spent on the environmental protection activity or environmental awareness activity into points.

[0189] Furthermore, in this embodiment, the compensation 500 for the environmental value 400 may be not only money or goods, but also another environmental value. Because the above-mentioned actions themselves have value, the environmental value 400 in this embodiment can improve the image of a company or organization simply by being certified or possessing it. Furthermore, it will raise awareness of environmental protection among members of the company or organization, further promoting activities that lead to environmental protection.

[0190] The configuration of the environmental value trading system used in this embodiment is the same as that of the environmental value trading system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the environmental value trading system according to this embodiment will be described, focusing on the differences from the first embodiment.

[0191] In this embodiment, in step S101 shown in Figure 3, when a plurality of first transactors 100 operate the input unit 11 of their own first communication terminal 10 to input the conditions for transferring the environmental value, they input a numerical value determined according to the points of the act of environmental protection activity or environmental awareness activity as the amount of the environmental value to be transferred. Also, in step S102, when a plurality of second transactors 200 operate the input unit 21 of their own second communication terminal 20 to input the conditions for receiving the environmental value, they input a numerical value determined according to the points of the act of environmental protection activity or environmental awareness activity as the amount of the environmental value to be received.

[0192] The numerical value indicating the points for each activity action input in step S101 is received by the communication unit 31 of the server device 30 together with other delivery conditions in step S103 and stored in the memory unit 33. Meanwhile, the numerical value indicating the degree of achievement of each activity action input in step S102 is also received by the communication unit 31 of the server device 30 together with other receiving conditions in step S103 and stored in the memory unit 33.

[0193] Fig. 22 is a diagram showing an example of a database stored in the storage unit 33 according to the seventeenth embodiment. A first database 331q shown in Fig. 22 stores a numerical value indicating points for environmental protection activities or environmental awareness activities as one of the conditions for transferring environmental value. Meanwhile, a second database 332p also stores a numerical value indicating points for environmental protection activities or environmental awareness activities as one of the conditions for receiving environmental value.

[0194] Then, in step S105, the discrimination unit 32 calculates the difference between the numerical value of the delivery condition and the numerical value of the receipt condition, and discriminates based on a preset degree of condition conformance according to the amount of difference. The discrimination result is displayed on the output unit 13 of each first communication terminal 10 in step S107, and on the output unit 23 of each second communication terminal 20 in step S108. Therefore, the first transactor 100 and the second transactor 200 can refer to the degree of condition conformance of points for environmental protection activities or environmental awareness activities when selecting a trading partner.

[0195] According to the present embodiment described above, even if the environmental value is a different type from that in the first embodiment, the environmental value trading system 1 can be used to match companies or organizations that wish to transfer environmental value with companies or organizations that wish to receive environmental value, thereby promoting transactions. This makes it possible to stimulate environmental value trading and promote environmental protection. In particular, in this embodiment, environmental protection can be further promoted by treating environmental protection activities or environmental awareness activities as the environmental value 400.

[0196] (18th embodiment) In the eighteenth embodiment, the type of environmental value 400 differs from that in the first embodiment. The environmental value 400 in this embodiment is the execution of an act of investing in a stock company that is carrying out a business that leads to environmental protection. An act of investing in a stock company that is carrying out a business that leads to environmental protection is, for example, an act of investing in a company that is carrying out a business that promotes forest conservation such as renewable energy, carbon dioxide capture and storage, recycling, and afforestation. Note that afforestation is also useful for carbon dioxide fixation.

[0197] The execution of the above investment actions is certified by the certifier 300. Furthermore, the amount of environmental value 400 is quantified in advance according to the execution content of each investment action. The points that comprehensively quantify the investment amount of each investment action and the evaluation of the investee business, i.e., the amount of environmental value 400, are also guaranteed by the certification 600 of the certifier 300. Note that points are set in advance for the evaluation of the investee business, for example, according to the content and scale of the business being implemented by the investee.

[0198] Furthermore, in this embodiment, the compensation 500 for the environmental value 400 may be not only money or goods, but also another environmental value. Because the above-mentioned actions themselves have value, the environmental value 400 in this embodiment can improve the image of a company or organization simply by being certified or possessing it. Furthermore, it will raise awareness of environmental protection among members of the company or organization, further promoting activities that lead to environmental protection.

[0199] The configuration of the environmental value trading system used in this embodiment is the same as that of the environmental value trading system 1 described in the first embodiment, and therefore a description thereof will be omitted. Here, the operation sequence of the environmental value trading system according to this embodiment will be described, focusing on the differences from the first embodiment.

[0200] In this embodiment, in step S101 shown in Figure 3, when a plurality of first traders 100 operate the input unit 11 of their own first communication terminal 10 to input the conditions for transferring environmental value, they input points related to investment in stock companies that are engaged in businesses that lead to environmental protection as the amount of environmental value to be transferred. Also, in step S102, when a plurality of second traders 200 operate the input unit 21 of their own second communication terminal 20 to input the conditions for receiving environmental value, they input the amount of investment in stock companies that are engaged in businesses that lead to environmental protection as the amount of environmental value to be received.

[0201] Each investment amount input in step S101 is received by the communication unit 31 of the server device 30 together with other delivery conditions in step S103 and stored in the memory unit 33. Meanwhile, each investment amount input in step S102 is also received by the communication unit 31 of the server device 30 together with other receiving conditions in step S103 and stored in the memory unit 33.

[0202] Fig. 23 is a diagram showing an example of a database stored in the storage unit 33 according to the eighteenth embodiment. In the first database 331r shown in Fig. 23, points related to investment in stock companies that are engaged in businesses that lead to environmental protection are stored as one of the conditions for transferring environmental value. Meanwhile, in the second database 332p, points related to investment in stock companies that are engaged in businesses that lead to environmental protection are also stored as one of the conditions for receiving environmental value.

[0203] Then, in step S105, the discrimination unit 32 calculates the difference between the investment amount for the delivery condition and the investment amount for the receipt condition, and discriminates based on a preset degree of condition conformance according to the difference. The discrimination result is displayed on the output unit 13 of each first communication terminal 10 in step S107, and on the output unit 23 of each second communication terminal 20 in step S108. Therefore, when selecting a trading partner, the first trader 100 and the second trader 200 can refer to the degree of condition conformance for points related to investment in stock companies that are engaged in businesses that contribute to environmental protection.

[0204] According to the present embodiment described above, even if the environmental value is different from that in the first embodiment, the environmental value trading system 1 can be used to connect companies or organizations that wish to transfer environmental value with companies or organizations that wish to receive environmental value, thereby promoting transactions. This makes it possible to stimulate environmental value trading and promote environmental protection. In particular, in this embodiment, environmental protection can be further promoted by treating the act of investing in stock companies that are engaged in businesses that lead to environmental protection as environmental value 400.

[0205] (19th embodiment) Fig. 24 is a schematic diagram for explaining an environmental value trading service according to the 19th embodiment. An environmental value trading 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. The server device 30 may be directly connected to the payment system 2, or may be connected via a network 40.

[0206] 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 consideration 500 to be paid by the second transactor 200 to the first transactor 100 from the receiving conditions stored in the memory unit 33. Next, the communication unit 31 transfers the read consideration 500 to the payment system 2.

[0207] The settlement system 2 performs a process of paying the consideration 500 to the first transactor 100. Here, an example of the process of paying the consideration 500 will be described. However, the content of the payment process is not limited to the following method.

[0208] 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 consideration 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 consideration 500 from the account number of the second transactor 200 and transferring it to the account number of the first transactor 100.

[0209] According to the present embodiment described above, the payment process is smoother because the payment system 2 performs the process of paying the consideration 500. As a result, the convenience of the environmental value trading service is further improved, which makes it possible to activate environmental value trading and promote environmental protection.
