Hereinafter, with reference to the drawings, an example of a form for implementing the environmental value trading system, the environmental value trading method, and the environmental value trading program of the present invention will be described in detail.

(First Embodiment)
First, the overall configuration of the environmental value trading system according to the present embodiment will be described with reference to FIG.
The environmental value transaction system 10 is set up between the factory A, the customer B, and an intermediary who mediates between the factory A and the customer B.

Factory A has a device that discharges heat (not shown), a generator 20 that generates electricity by recovering medium- and low-temperature exhaust heat discharged from the device that discharges this heat, and power generation by the generator 20. It is equipped with a factory-side management device 30 capable of measuring the amount and transmitting the measurement result to the intermediary side.

The device that discharges heat is used when the raw material is processed in the factory A to produce a product, and the heat is used in the processing. The heat after being used for processing is not high temperature but medium and low temperature exhaust heat, which was conventionally dissipated into the atmosphere as shown in FIG. The medium / low temperature specifically means, for example, 200 degrees or less. This medium-low temperature exhaust heat is an example of unused energy, and is energy that has not been used so far even though it may be effectively used so far. In the present embodiment, a recovery device (not shown) for recovering the medium-low temperature exhaust heat is provided.

The generator 20 is a device that generates electricity by utilizing the medium and low temperature exhaust heat recovered by the recovery device. Specifically, this generator 20 is a binary generator, which uses the recovered medium- and low-temperature waste heat to heat and evaporate a medium having a low boiling point, and uses the steam to turn a turbine to generate electricity. Is. The steam that turned the turbine is cooled and returned to the liquid, and when it returns to the liquid, it is heated again to generate steam to turn the turbine, and the medium circulates evaporation while repeating liquefaction. In the process of power generation, almost no gas that adversely affects the environment such as carbon dioxide and sulfur oxides is generated. Although pentane (boiling point of about 36 degrees) is used as the medium, other media such as ammonia, CFC substitutes, and water may be used.

In the present embodiment, the binary generator as described above is used, but the present invention is not particularly limited to this, and any generator that can utilize exhaust heat can be used as a Stirling engine or a thermoelectric conversion element. Other types of generators that utilize the above may be used.

In the present embodiment, exhaust heat as unused energy discharged from the factory is recovered, and the recovered exhaust heat is used to generate electricity by a generator and consumed in the factory A to reduce the amount of electricity purchased. It creates environmental value, which is the value that reduces the burden on the environment.

The factory-side management device 30 manages the operating state of the generator 20. The factory-side management device 30 measures the amount of power generated by the generator 20 and transmits the measurement result to the environmental value transaction server 40 of the intermediary using a network line.
The number of factories A that provide environmental value is one, but may be multiple (see FIG. 8).

In the environmental value trading system according to the present embodiment, the intermediary has an environmental value trading server 40 and an energy facility 50.

The environmental value transaction server 40 calculates the environmental value corresponding to the amount of power generation received from the factory A, purchases the environmental value, and processes the payment of the purchase price to the factory A.

The environmental value transaction server 40 stores the environmental value transaction program in advance.
This environmental value trading program stores the amount of power generation based on the measurement result of the amount of power generation by the generator 20 that generates power by recovering the exhaust heat as unused energy discharged from the factory A, and the amount of power generation. When the purchase request for purchasing the environmental value corresponding to the above is received, the environmental value purchase process is performed, and the environmental value purchase condition for purchasing the environmental value from the consumer side terminal 60 of the consumer B via the network line is set. When it is accepted, it functions as a control means 47A for selling the environmental value.

Specifically, the environmental value transaction server 40 acquires the measurement result of the amount of power generated by the generator 20 via the factory-side management device 30, and stores the acquired measurement result.
The environmental value transaction server 40 calculates the environmental value corresponding to the amount of power generated by the generator 20, and when it receives the purchase request of the environmental value including the desired purchase amount and the desired purchase unit price by the intermediary, the environment according to the purchase amount is received. By deriving the value price (corresponding to the purchase price), sending it to the factory management device 30 for presentation, and receiving approval from the factory management device 30 on the factory side, payment processing is performed to the factory A. I do. Then, the amount of power generated by the factory A is subtracted by the amount corresponding to the purchased amount.

Here, the environmental value transaction server 40 can input the desired purchase amount and the desired purchase unit price of the environmental value by the intermediary via the input device 41 (see FIG. 3). The purchase request for the environmental value derived from the desired purchase amount and the desired purchase unit price is transmitted by the communication device 43 to the factory management device 30 via the network line. These contents are presented to the factory side management device 30.
In this embodiment, the intermediary company inputs the desired purchase amount of the environmental value and the desired purchase unit price by the input device 41, and transmits the purchase request of the environmental value including these to the factory side management device 30 on the factory A side. However, it is not particularly limited to this. For example, the desired purchase amount and the desired purchase unit price of the environmental value may be input by the factory A side from the factory side management device 30, and the purchase request for the environmental value may be transmitted from the factory side management device 30 to the environmental value transaction server 40. .. In that case, the approval for the purchase request will be transmitted by the intermediary to the factory A side by the environmental value transaction server 40.
Further, for example, a purchase request including the purchase amount is transmitted from the factory side management device 30 on the factory A side to the environmental value transaction server 40 on the intermediary side, and the intermediary who sees the presentation inputs the environmental value transaction server 40. The desired purchase amount and the desired purchase unit price are input by the device 41, the contents are transmitted to the factory side management device 30, and the signal of approval of the factory A side for the transmitted contents is an environmental value transaction from the factory side management device 30. It may be transmitted to the server 40 side.

The energy facility 50 is its own power generation facility for generating electric power to be sold to the consumer B, and specifically has a thermal power generation facility. Natural gas is used as the fuel in the thermal power generation facility, but other fuels such as petroleum and coal may be used as long as they convert the reaction heat energy of the fuel into electric power. The energy equipment 50 is not limited to thermal power generation equipment, and may be other equipment as long as it is equipment that converts energy other than electric power into electric power.

The environmental value transaction server 40 accepts the environmental value purchase condition and the energy purchase condition for purchasing energy transmitted from the consumer side terminal 60 of the consumer B via the network line, so that the consumer desires. It is possible to have consumers purchase the environmental value of the quantity at the desired timing.

The environmental value transaction server 40 adds the environmental value purchased from the factory A to the electric power generated by itself and sells it to the consumer, and adds the purchased environmental value to the electric power to the consumer. The sale process is performed. That is, whether or not the environmental value transaction server 40 receives the environmental value purchase condition and the energy purchase condition from the consumer side terminal 60 of the consumer, presents them on the display device 42 (see FIG. 3), and approves them by the intermediary. Let them make a decision. When it is determined that the intermediary company approves, the intermediary company is made to perform the approval process via the input device 41 (see FIG. 3), and when the approval process is performed, the approval is accepted.

When the environmental value transaction server 40 receives the approval from the input device 41, the environmental value transaction server 40 transmits the approval signal to the consumer side terminal 60. Upon receiving the purchase confirmation signal from the consumer side terminal 60 with respect to this approval signal, energy can be supplied to the consumer. Specifically, it makes it possible to transmit electric power as energy. At the same time, the environmental value transaction server 40 transmits the proof data for purchasing the environmental value to the customer, and processes the receipt of the sales price from the customer.
Instead of electricity, the intermediary may sell energy sources such as gas, heat, oil, coal, and gasoline, or some kind of product together with environmental value.

The consumer-side terminal 60 inputs the energy purchase condition including the desired purchase amount and the desired purchase unit price of electric power as energy and the environmental value purchase condition including the desired purchase amount and the desired purchase unit price of the environmental value 61 (Fig. It is possible to input via 4). The input energy purchase condition and environmental value purchase condition signals are transmitted to the environmental value transaction server 40 by the communication device 63 via the network line. The specific contents of the energy purchase condition and the environmental value purchase condition are displayed on the display device 42 (see FIG. 3) of the environmental value transaction server 40.

The intermediary company compares and collates various conditions including the cumulative value of the purchased environmental value with the environmental value purchase condition and the energy purchase condition from the consumer B, and finds that both conditions are met (matched). If it is determined, the approval process of transmitting a signal meaning an approval message to the consumer side terminal 60 is performed. The approval process is automatically performed without human intervention by a pre-installed program that determines whether or not the various conditions including the cumulative value of the environmental value, the environmental value purchase condition, and the energy purchase condition are met. The judgment process may be performed.

The energy and environmental value that the environmental value transaction server 40 causes the consumer to purchase via the network line are set so as to have a predetermined correspondence relationship between the amount of energy and the amount of environmental value. Specifically, it is set so that there is a certain proportional relationship between the amount of energy to be purchased and the amount of environmental value by a predetermined proportional coefficient.
This proportional coefficient is calculated based on the carbon dioxide emission factor or the like with respect to the unit energy amount even when the type of energy differs depending on the electric power, gas, or the like. Of course, the present invention is not limited to this, and the intermediary may freely set it.

Upon receiving a message from the environmental value transaction server 40 approving the purchase conditions (environmental value purchase conditions and energy purchase conditions), the consumer-side terminal 60 receives the purchase conditions (environmental value purchase conditions and energy purchase conditions) within a predetermined period. It is possible to send a signal of purchase confirmation under the energy purchase condition) to the environmental value transaction server 40. When the purchase confirmation signal is transmitted from the consumer-side terminal 60 to the environmental value transaction server 40 within the predetermined period, it means that the sale and purchase under the purchase conditions (environmental value purchase conditions and energy purchase conditions) have been completed, and the demand. House B can purchase energy and environmental value.
If the purchase confirmation signal from the consumer-side terminal 60 is not transmitted to the environmental value transaction server 40 within a predetermined period, the sale and purchase of energy and environmental value will not be completed. Here, the "predetermined predetermined period" is set to one day (24 hours), but is not particularly limited to this, and may be set to another period.

The consumer-side terminal 60 processes the payment of the purchase price according to each purchase amount of energy and environmental value. By purchasing environmental value as well as electric power as energy, consumers can appeal to the outside world the implementation of environmental measures such as carbon dioxide reduction.
In the present embodiment, the number of customers B who purchase the environmental value is one, but may be plural.

Further, in the present embodiment, the intermediary has a power generation facility as the energy facility 50, and when selling the electric power generated by the energy facility to the consumer B, the electric power and the environment purchased from the factory A. It sells with value, but is not limited to this. For example, the intermediary may not sell energy such as electric power to customer B without having the energy equipment 50, and may sell only the environmental value purchased from factory A to customer B (FIG. 7). reference).

FIG. 2 is an explanatory diagram showing a relationship between a conventional factory and an electric power company having a power generation facility. Factory A purchases the energy (electric power) generated by the power generation equipment of the electric power company and pays the energy charge (electric energy charge). Factory A manufactures products using a device that generates heat using the energy, and the medium- and low-temperature exhaust heat generated by the device is dissipated into the atmosphere.
In the first embodiment, the medium-low temperature exhaust heat that was dissipated into the atmosphere at the factory in this conventional form is converted into an environmental value, and the intermediary purchases this environmental value and sells it to the customer B.

In step 111, the environmental value transaction server 40 performs a calculation process of the amount of power generation transmitted from the factory. Specifically, the environmental value trading server 40 uses the medium- and low-temperature exhaust heat transmitted this time from the factory A to generate the amount of power generated by the generator 20 in January, and the same amount of power generated so far. The accumulated power generation amount (pre-purchase power generation amount) is added to the amount of power generation that has not been purchased from the intermediary, and the added value is stored in the non-purchase memory 44D as a new pre-purchase power generation amount. Then, the process proceeds to the next step 112.

In step 112, the environmental value transaction server 40 calculates the environmental value corresponding to the newly determined pre-purchase power generation amount, and sets it as the new pre-purchase environmental value.
Here, the environmental value corresponding to the amount of power generation is calculated by multiplying the amount of power generation by a predetermined coefficient. Of course, the calculation method of the environmental value is not limited to this, and any other calculation method may be used as long as it is calculated according to a certain rule, and the amount of power generation is a predetermined value. If it is within the range, a predetermined amount of environmental value may be set.
Then, the process proceeds to the next step 113.

In step 113, it is determined by the environmental value transaction server 40 of the intermediary whether or not there is a purchase request including the desired purchase amount and the desired purchase unit price. If it is determined that there is a purchase request, the process proceeds to the next step 114, and if it is determined that there is no purchase request, the process ends.

In step 114, the environmental value transaction server 40 derives the purchase amount and the purchase price according to the purchase amount based on the purchase request. Specifically, it is calculated based on the desired purchase amount and the desired purchase unit price, and the purchase price is calculated by multiplying the purchase amount by a predetermined coefficient. Of course, the purchase price is not limited to this, and the purchase price may be calculated by different coefficients depending on the range including the purchase amount, for example. The calculated purchase price and the like are presented to the factory management device 30. Then, the process proceeds to the next step 115.

In step 115, it is determined whether or not the approval has been obtained from the factory side management device 30 on the factory A side. If it is determined that the factory A has been approved, the process proceeds to the next step 116, and if it is determined that there is no approval, the process ends.
In step 116, the purchase process is performed by the environmental value transaction server 40. Specifically, a payment process is performed in which the purchase price corresponding to the purchase price is paid to the factory A. Then, the process proceeds to the next step 117.

In step 117, the environmental value transaction server 40 performs a process of calculating the pre-purchase power generation amount that has not yet been purchased and the cumulative value of the purchased environmental value according to the purchase amount.

Specifically, the amount of power generation corresponding to the current purchase amount is subtracted from the amount of power generation before purchase, and the value after the subtraction is set as the new amount of power generation before purchase.
In addition, the amount purchased this time is added to the cumulative value of the environmental value that has already been purchased, and the value after the addition is set as the new cumulative value of the environmental value that has already been purchased.
Then, the process proceeds to the next step 118.

In step 118, the environmental value transaction server 40 stores the amount of power generation before purchase and the like in the non-volatile memory 44D. Then, the process ends.
The process is repeatedly executed.

In the present embodiment, the above-described calculation process is executed by the environmental value transaction server 40, but the factory-side management device 30 executes a calculation process such as a calculation process of the amount of power generation to perform the calculation process. The later power generation amount may be transmitted to the environmental value trading server 40.

FIG. 6 is a flowchart illustrating an example of the flow of environmental value transactions in the environmental value transaction system.

In step 210, the environmental value transaction server 40 determines whether or not the consumer B is transmitting the environmental value purchase condition and the energy purchase condition via the consumer side terminal 60. If it is determined that the environmental value purchase conditions and energy purchase conditions have been transmitted, the process proceeds to the next step 211, and if it is determined that the environmental value purchase conditions and energy purchase conditions have not been transmitted, the step Return to 210.

In step 211, the environmental value transaction server 40 performs a process of presenting the environmental value purchase condition and the energy purchase condition transmitted from the consumer side terminal 60 to the display device 42. Then, the process proceeds to the next step 212.

In step 212, the environmental value transaction server 40 stores the desired purchase amount and desired purchase unit price of the environmental value from the consumer side terminal 60, and the purchased environmental value stored in the non-volatile memory 44D of the environmental value transaction server 40. Is compared with the cumulative value of the above and the planned sales unit price.

Further, the environmental value trading server 40 generates the desired purchase amount and desired unit price of energy (electric power) from the consumer side terminal 60 and the power generation of the energy equipment 50 stored in the non-volatile memory 44D of the environmental value trading server 40. Comparison processing with the plan contents is performed.
Then, the process proceeds to step 213.

In step 213, as a result of the condition comparison process in step 212, it is determined whether or not the conditions for successful sale are met. If it is determined that the conditions for closing the sale are met, the process proceeds to the next step 214, and if it is determined that the conditions are not met, the process ends.
In step 214, the approval process is performed by the environmental value transaction server 40. Specifically, the environmental value transaction server 40 outputs a signal to the consumer side terminal 60 to approve the environmental value purchase condition and the energy purchase condition. Then, the process proceeds to the next step 215.

In step 215, it is determined whether or not the purchase from the consumer-side terminal 60 has been confirmed within a predetermined period (specifically, one day (24 hours)) after the signal to the effect of approval is output. If it is determined that the purchase has been confirmed, the process proceeds to the next step 216, and if it is determined that the purchase has not been confirmed, the process ends.

In step 216, the transaction completion process is performed by the environmental value transaction server 40. The process of establishing the sale and purchase of energy and environmental value for the environmental value purchase condition and the energy purchase condition from the consumer B is performed. Specifically, the purchase and sale of energy and environmental value is completed for the consumer B. Message, billing processing of the purchase price to the consumer B, and the like are transmitted to the consumer side terminal 60 via the network line. Then, the process proceeds to the next step 217.

In step 217, the energy supply availability setting process is performed by the environmental value transaction server 40. Specifically, the electric power generated by the power generation facility as the energy facility 50 owned by the intermediary can be output to the consumer B. Then, the process proceeds to step 218.
In step 218, the environmental value transaction server 40 transmits proof data to the effect that the consumer B has acquired the desired purchase amount of the environmental value from the consumer side terminal 60 to the consumer side terminal 60. Arrangements may be made so that the predetermined certificates and the like are sent to the customer B by mail or the like. Then, the process proceeds to step 219.

In step 219, the environmental value transaction server 40 sets the balance obtained by subtracting the environmental value purchased by the consumer B from the cumulative value of the purchased environmental value as a new cumulative value of the purchased environmental value, and sets the non-volatile memory. It is stored in 44D. Then, the process ends.

In the present embodiment, by having the above-described configuration, the following actions and effects are exhibited.

In this embodiment, the electric power generated in the factory A is not reverse-flowed, and no electric power is exchanged between the factory A and the customer B in the commercial power system, and the electric power is not exchanged from the factory A. The environmental value of power generation using the waste heat of the power generation is sold separately from the generated power.
If the electricity obtained from the power generation using the exhaust heat of the factory A is to be transmitted from the factory A to the customer B using the commercial power system, it is necessary to bear the consignment fee when using the commercial power system. Along with power transmission, various costs are required, such as power loss due to heat generation of electric resistance, equipment for supplying power to commercial power, and maintenance of these facilities is difficult.
In the present embodiment, it is possible to significantly reduce the cost as compared with the one using such a commercial power system, and such a cost burden is borne by both the factory A side and the customer B side. It will be a big profit.

In the present embodiment, the exhaust heat as unused energy discharged from the factory A is recovered, and the recovered exhaust heat is used to generate electricity by a generator and consumed in the factory A to reduce the amount of electricity purchased. This creates environmental value, which is the value that reduces the burden on the environment.

According to this embodiment, the environmental value is calculated according to the amount of electric power obtained by using the exhaust heat as unused energy emitted from the factory A for power generation. By purchasing this environmental value from the factory A and having the customer purchase the purchased environmental value, the environmental value can be traded between the mediator and the customer.

By allowing consumers to purchase environmental value, it is possible to facilitate the implementation of environmental measures by consumers and promote the effective utilization of unused energy.
In addition, the amount of power generated by using the exhaust heat as unused energy for power generation is measured, the environmental value corresponding to the amount of power generation is calculated, and the amount of environmental value desired by the consumer is desired at the desired timing. It can be purchased and the transaction of environmental value can be activated.

As a result, the effective utilization of unused energy can be promoted, and the spread of power generation by the unused energy emitted from the factory A can be supported.
In addition, since it is possible to give an economic value of environmental value to the unused energy of factory waste heat, it becomes an incentive for effective utilization of unused energy, and at the same time, it is possible to spread the environmental value of effective utilization of unused energy to society.

According to the present embodiment, the intermediary can input the desired purchase amount of the environmental value and the desired purchase unit price by the input device, and the intermediary can input the desired amount and unit price of the environmental value to the factory A side. You can contact me.

According to the present embodiment, the factory side management device 30 causes the factory A side to present a purchase request from the environmental value transaction server 40. When the factory side management device 30 receives the approval of the factory A side for the purchase request, the factory side management device 30 transmits a signal of approval to the environmental value transaction server 40. This allows the intermediary to buy the environmental value.

According to the present embodiment, the intermediary can purchase the desired amount of environmental value at the will of the intermediary.

According to the present embodiment, when the intermediary sells the environmental value together with the energy, when the intermediary sells the energy, it is possible to give a privilege as an added value of the environmental value, and the environmental value is the intermediary. It can be used as a tool to promote the sale of energy in Japan.

That is, it is possible to add value such as energy saving (saving fossil fuels) and carbon dioxide emission control to the value of energy itself such as gas and electricity sold by an intermediary.

By adjusting the amount of environmental value to an appropriate amount with respect to the amount of energy sold by the intermediary, for example, as the electricity to be sold, the consumer B uses electricity that does not emit carbon dioxide. It is also possible to look at it, and consumer B can utilize it as an environmental measure and a global warming measure, for example, it can be described in an environmental report, a CSR report, or the like.

According to the present embodiment, the environmental value transaction server 40 causes the display device 42 to present the environmental value purchase condition and the energy purchase condition based on the environmental value purchase condition and the energy purchase condition from the consumer side terminal.
When the environmental value transaction server receives the approval of the intermediary for the environmental value purchase conditions and the energy purchase conditions, it transmits an approval signal to the consumer side terminal 60, and then sends a purchase confirmation signal from the consumer side terminal 60. Upon receiving the signal, the energy can be supplied to the consumer, and the proof data of purchasing the environmental value is transmitted to the terminal 60 on the consumer side.

As a result, consumers can purchase energy and environmental value, and by obtaining proof data of purchasing environmental value, it is possible to appeal to the outside world the implementation of environmental measures such as carbon dioxide reduction. Become.
The environmental value transaction server 40 receives and processes the purchase price according to the purchase amount of energy and environmental value from the consumer. In this way, the environmental value transaction server 40 can stand between the factory A and the customer B and manage the entire environmental value transaction including the exchange of payment, and promote the environmental value transaction. be able to.

According to the present embodiment, the consumer can input the desired purchase amount and the desired purchase unit price of the environmental value by the input device 61, and also input the desired purchase amount and the desired purchase unit price of electric power as energy. It can be input by 61. As a result, the consumer can easily inform the intermediary of the environmental value, the desired amount of electric power, and the unit price.

According to this embodiment, there is a predetermined correspondence between the amount of energy that the intermediary company makes the consumer purchase and the amount of environmental value.

On the other hand, since the environmental value corresponds to the amount of power generation at the factory A, there is a predetermined correspondence relationship between the amount of the environmental value and the amount of power generation at the factory A.
For this reason, there is a certain quantitative response between the amount of power generated by the exhaust heat of factory A, the amount of energy that the intermediary has to make consumers purchase, and the amount of environmental value. Relationships can arise.

By creating a predetermined correspondence between these three quantities, the amount of environmental value purchased by consumer B can be adjusted to an appropriate amount commensurate with the amount of power generated using the exhaust heat of factory A. It is possible to ensure the legitimacy and consistency of the environmental value to be bought and sold.
Specifically, for example, it is possible for a consumer to purchase the same amount of energy as the amount of power generated by a generator in a factory or an amount corresponding to the amount of power generated, and purchase the environmental value corresponding to the amount of the energy. It becomes.

As a result, consumers can purchase energy and environmental value as a set from an intermediary to reduce the amount of fossil fuels and carbon dioxide emissions that are appropriate for the amount of energy purchased. It is possible to obtain environmental value as an added value.

According to this embodiment, the factory side can reduce the amount of power purchased from the commercial power system and sell the environmental value by consuming the power generated by the generator in the factory. As a result, the purchase price can be obtained, and it becomes possible to obtain an economic gain.
The environmental value of the factory will be deducted by the amount of the purchased environmental value, but it can be beneficial to those who value economic gain rather than environmental value.

According to the present embodiment, by using a binary generator that uses a low boiling point medium, efficient power generation can be performed even when the temperature of exhaust heat steam, hot water, etc. is medium or low and not high. Can be done.

According to this embodiment, by using the environmental value transaction program, the environmental value can be purchased by the consumer without going through the commercial power system with the factory. It is possible to facilitate the implementation of environmental measures and promote the effective utilization of unused energy.

As a result, according to the present embodiment, it is possible to promote the effective utilization of unused energy generated in the factory and to activate the transaction of the obtained environmental value without going through the commercial power system.

In the present embodiment, the purchase condition is transmitted from the consumer side terminal 60 on the consumer side to the environmental value transaction server 40, and in response to this, an approval message is sent from the environmental value transaction server 40 to the consumer side terminal 60. After that, a signal of purchase confirmation was transmitted from the consumer side terminal 60 to the environmental value transaction server 40, and the buying and selling of the environmental value and the like was completed, but the trading exchange is not particularly limited to this. No. For example, by transmitting an approval message from the environmental value transaction server 40 to the consumer side terminal 60, even if the purchase confirmation signal is not transmitted from the consumer side terminal 60 to the environmental value transaction server 40, the purchase and sale of the environmental value May be completed.

Further, instead of setting the purchase condition from the consumer side as described above at the beginning of the sale, for example, the sales condition which is the condition for selling the environmental value or the like from the environmental value transaction server 40 is transferred to the customer side terminal 60. Upon presentation, the consumer-side terminal 60 sends an approval signal to the environmental value transaction server 40 to approve the sales conditions, and then the environmental value transaction server 40 confirms the sale to the consumer-side terminal 60. A signal may be transmitted to complete the sale and purchase of environmental value and the like. At that time, the transmission of the sales confirmation signal may be omitted when the sale is completed.
