Description

  The present invention relates to information processing technology, and more particularly to information processing technology that contributes to the spread of ETC systems (Electronic Toll Collection System: digital operation management system).

  In order to prevent global warming, movements to reduce carbon dioxide emissions are spreading worldwide. With the aim of reducing carbon dioxide emissions, there is already a green car tax system and a green purchasing system in Japan, and the introduction of a carbon tax that charges fuel itself is also being considered. In addition, a carbon dioxide emission market system is being introduced as a system for suppressing carbon dioxide emissions. A carbon dioxide emission right is a right that an operator or the like can emit carbon dioxide in accordance with its business activities, and its market system is a target for a carbon dioxide emission right for commercial transactions.

  For example, a business operator who has performed a carbon dioxide fixing business such as afforestation is authorized for carbon dioxide emission according to the scale, and can sell it to a carbon dioxide emission business. In addition, companies that have been able to reduce their carbon dioxide emissions from the carbon dioxide reduction target value imposed on carbon dioxide emission companies, etc. sell carbon dioxide emission rights according to the reduction amount to other companies. be able to. A carbon dioxide emission company or the like that cannot achieve the carbon dioxide reduction target value can achieve the reduction target value by purchasing a carbon dioxide emission right from another company.

  In order to smoothly operate such a carbon dioxide emission market system, a technique for calculating carbon dioxide emission (for example, Patent Document 1) and a technique for electronic trading of carbon dioxide emission rights (for example, Patent Document 2). Has also been proposed.

  On the other hand, tollgate congestion on highways causes unnecessary carbon dioxide emissions from automobiles, contributing to global warming. However, in general, traveling on a highway has less carbon dioxide emissions per unit length than traveling on a general road. From the viewpoint of environmental impact, a highway should be used rather than a general road. . The introduction of the ETC system has been effective in eliminating tollgate congestion on highways. However, the use of the ETC system is not necessarily widespread, and the promotion of the use is desired.

  Due to the increase in environmental awareness of ordinary people, an increasing number of people are willing to bear a small cost. However, at present, only discount systems are implemented as measures for promoting the use of expressways and spreading ETC systems.

  In the information processing method of the present invention, the right to acquire carbon dioxide emission rights is given to the user according to the degree of use of the expressway using the ETC system. For this reason, the use of the ETC system is promoted, the tollgate congestion on the highway is eliminated, and unnecessary carbon dioxide emission from the automobile is suppressed. In addition, highways are more easily used than ordinary roads, and carbon dioxide emissions from automobiles can be reduced. Therefore, it is possible to provide a mechanism that contributes to environmental conservation by promoting the use of the ETC system and the expressway. Moreover, since a series of processes can be automated, the operation is facilitated. The users may not necessarily be all users of the ETC system, but may be limited to registered registrants who wish to acquire carbon dioxide emission rights.

  The present invention further includes a third database that stores information on carbon dioxide emission rights held by the right holder for each right holder of carbon dioxide emission rights, and a third update step for updating the second database. In the third updating step, when the carbon dioxide emission right is transferred from the right holder to the user, the acquisition right of the user is obtained from the second database according to the transferred carbon dioxide emission right. And the carbon dioxide emission right of the right holder can be subtracted from the third database.

  According to this configuration, it is possible to smoothly trade carbon dioxide emission rights from the right holder of carbon dioxide emission rights to the user.

  In the present invention, it is preferable that the third database stores information on carbon dioxide emission rights acquired by the carbon dioxide fixation business.

<CO2 emission trading system>
FIG. 1 is an explanatory diagram of a carbon dioxide emission trading scheme that can be realized by an embodiment of the present invention. The expressway management organization 100 is, for example, the Japan Highway Public Corporation and its related organizations, and is an organization that manages the operation of the ETC system and the operation of the expressway. In the present embodiment, the highway management organization 100 is mainly responsible for trading carbon dioxide emission rights. The toll booth 101 is a toll booth provided on each highway, and in the case of this embodiment, it is a toll booth in which an ETC system is introduced.

  The ETC system user 102 is a natural person or a corporation registered to use the ETC system. This user 102 is an automobile equipped with an on-board device of ETC and can use the highway through the gate of the ETC system at the toll booth 100 in each place. The expressway management organization 100 collects and aggregates information on the use of the expressway using the ETC system from each tollgate 101, and later, the user charges the expressway usage fee to each user 102 through a card company or the like. You will be charged. The highway usage fees paid from each user 102 are pooled in a predetermined deposit account 103 a of the bank 103.

  On the other hand, the carbon dioxide fixation company 104 is, for example, a construction company or the like, and is a company that leads to the reduction of carbon dioxide emissions, such as a tree planting business. When a carbon dioxide fixation project such as afforestation is performed, the amount of carbon dioxide emission reduction is calculated according to the scale, and the carbon credits are issued by Certifying Authority (CDM Executive Board, etc.) 105 (CER issuance: certified) Emission reduction amount (Certified Emission Reduction) is given. When the carbon dioxide fixation company 104 to which the carbon dioxide emission right is granted desires to sell the carbon dioxide emission right, it applies to the expressway management organization 100.

  Here, as described above, traveling on a highway generally has less carbon dioxide emissions per unit length than traveling on a general road, so the use of the highway contributes to the reduction of carbon dioxide emissions. . In addition, tollgate congestion on expressways unnecessarily emits carbon dioxide from automobiles and contributes to global warming. However, the use of the ETC system promotes the elimination of traffic congestion by using the ETC system. Has also contributed to reducing carbon dioxide emissions.

  Therefore, the highway management institution 100 mediates between the carbon dioxide fixation company 104 and the user 102, or once purchases carbon dioxide emission rights and releases the carbon dioxide to the highway user 102 using the ETC system. Transfer rights. A carbon dioxide emission right is given to the user 102 according to the use degree of the highway. The more the user 102 uses the expressway, the more carbon dioxide emission rights can be obtained. On the other hand, the expressway management institution 100 pays the carbon dioxide fixing company 104 for the carbon dioxide emission right, and the expressway management institution 100 charges the usage fee of the expressway pooled in the deposit account 103a according to the degree. Appropriate. The expressway management institution 100 issues an instruction to pay the carbon dioxide emission right to the bank 100, and the carbon dioxide fixing company 104 obtains the carbon dioxide emission right through the bank 103. This consideration is expected to be invested in a new carbon dioxide fixation project. Thereafter, the expressway management organization 100 performs necessary procedures such as a transfer registration procedure for carbon dioxide emission rights to the carbon dioxide fixing company 104.

  According to such a mechanism, since the user 102 can obtain a carbon dioxide emission right according to the degree of use of the expressway using the ETC system, the use of the ETC system and the expressway is promoted. The spread of the ETC system eliminates toll congestion and contributes to environmental conservation because the usage rate of expressways is higher than that of ordinary roads. Furthermore, the carbon dioxide fixation company 104 can easily find a supplier of carbon dioxide emission rights obtained through the carbon dioxide fixation business, and the exchange of money is facilitated. For this reason, a carbon dioxide fixation business is promoted and it can contribute to environmental conservation further.

<System>
Next, a system for smoothly managing the above-described transaction mechanism will be described. FIG. 2 is a block diagram of a transaction system according to an embodiment of the present invention. In the present embodiment, the above-described transaction mechanism can be smoothly managed by automating the processing by the server computer.

  The information processing server A mainly executes processing performed by the expressway management organization 100 and is managed by the expressway management organization 100. The information processing server A has toll gate terminals 10a to 10c (hereinafter collectively referred to as toll gate terminals) of a large number (three are illustrated here) of toll gates deployed on highways in various places via the network 30a. 10)) so that communication is possible. The toll booth terminal 10 is a toll booth terminal in which the ETC system is introduced, executes processing related to the ETC system at each toll booth, and obtains usage information indicating the usage status of the expressway of the user 102 using the ETC system. It transmits to the information processing server A.

  The usage information DB (database; the same applies hereinafter) 20a is a database in which usage information indicating the usage status of the expressway using the ETC system is accumulated for each user 102. FIG. 3B is a diagram showing an example of usage information. “User” is information for identifying each user 102, and the name of the user is illustrated in the example of the figure, but may be a code assigned to each user, for example. “Usage status” indicates the usage status of the expressway of each user 102 using the ETC system, “use date” using the expressway, “entrance” as information when entering the expressway, expressway The information when exiting the road includes “exit”, “vehicle type” indicating the type of automobile at that time, and “usage fee” indicating the usage fee. The information of “entrance” and “exit” further includes “toll gate” that is information for specifying the toll gate that has passed, and “time” that is information for specifying the time of passage. Needless to say, only information on “entrance” is used for expressways that collect a fixed amount at the entrance, such as the Metropolitan Expressway. “Vehicle types” include large, medium, small and normal.

  As will be described later, in this embodiment, the right to acquire carbon dioxide emission rights of each user 102 is set based on this usage information. The content of the usage information shown in FIG. 3B is an example, and it is sufficient that the usage information has information in a range necessary for setting an acquisition right. In addition, the usage information DB 20a does not need to store usage information of all users of the ETC system. For example, a carbon dioxide emission right is granted only to registered users who wish to acquire carbon dioxide emission rights. In such a case, it is sufficient to accumulate usage information regarding the registered user.

  Returning to FIG. 2, the acquisition right information DB 20 b is a database in which information on the acquisition right of carbon dioxide emission rights (hereinafter referred to as acquisition right information) is stored for each user 102. FIG. 3C is a diagram showing an example of acquisition right information. “User” is information for identifying each user 102, and the name of the user is illustrated in the example of the figure, but may be a code assigned to each user, for example. The “acquisition right” is information indicating the degree of carbon dioxide emission right that the user 102 can acquire, and here, the amount of carbon dioxide (unit: tons) is exemplified, but the user can acquire carbon dioxide. Other units or information of no units may be used as long as they indicate the level of carbon emission rights.

  Returning to FIG. 2, the emission right information DB 20c is a database in which information on carbon dioxide emission rights possessed by each right holder of carbon dioxide emission rights is accumulated. Although the present invention can be applied to trading of carbon dioxide emission rights other than the carbon dioxide emission rights obtained by the carbon dioxide fixation business, in this embodiment, the carbon dioxide emission rights obtained by the carbon dioxide fixation business are traded. This emission right information DB 20c is a carbon dioxide fixing company 104 to which a carbon dioxide emission right is granted, and sells the carbon dioxide emission right to the expressway management organization 100. Information on the carbon dioxide emission rights of the applicant is accumulated.

  FIG. 3D shows an example of emission rights information. The “right holder” is information for identifying each carbon dioxide fixed company 104, and the name of the right holder is illustrated in the example of the figure, but may be a code assigned to each right holder, for example. “Emission rights” is information indicating the degree of carbon dioxide emission rights that can be sold by the carbon dioxide fixing company 104, and here, the amount of carbon dioxide (unit: tons) is exemplified, but the carbon dioxide emission rights The information should be in line with the unit. The “transfer account” is information relating to the account of the transfer destination of the consideration for the carbon dioxide emission right, and is specified by the carbon dioxide fixing company 104.

  Returning to FIG. 2, the information processing server A is connected to the user terminal 40 used by the user 102, the carbon dioxide fixation operator terminal 41 used by the carbon dioxide fixation operator 104, and the deposit management via the network 30 b. Communication with the servers 50 and 51 is possible. The user terminal 40 is a personal computer or the like owned by the user 102. For example, in a case where a carbon dioxide emission right is given only to a registered user who desires to acquire a carbon dioxide emission right, It is used as a terminal for performing registration procedures on the information processing server A online. It also receives online notification of the result of granting carbon dioxide emission rights.

  The carbon dioxide fixation operator terminal 41 is a personal computer or the like owned by the carbon dioxide fixation operator 104, and is used, for example, when applying to the expressway management organization 100 for online sale of carbon dioxide emission rights. With this application, the emission rights information DB 20c is sequentially updated. In addition, a notification of the result of sales of carbon dioxide emission rights, etc. is received online. The deposit management servers 50 and 51 are servers managed by a bank, and are servers for realizing online transactions. In the case of the present embodiment, the deposit management server 50 is a server that manages information on the deposit account 103a of the bank 103 in which at least a part of the usage fee of the ETC system paid by the user 102 is deposited, and the deposit management server 51 is It is assumed that the server manages information on the deposit account of the carbon dioxide fixation company 104 that receives payment for the carbon dioxide emission rights. The networks 30a and 30b are the Internet, a local area network, etc., and are composed of wired and wireless communication lines.

  Next, the configuration of the information processing server A, the toll gate terminal 10, the user terminal 40, the carbon dioxide fixing company terminal 41, and the deposit management servers 50 and 51 will be described. Although there is a difference in processing capability and the like, basically a general computer configuration can be adopted. Here, the basic configuration will be described in common with reference to FIG. FIG. 3A is a block diagram of the information processing server A and the like. The CPU 201 is a processor that controls the entire information processing server A and the like. A ROM (Read Only Memory) 202 stores a basic program executed by the CPU 201. A RAM (Random Access Memory) 203 has a work area for programs processed by the CPU 201 and stores variable data and the like.

  The storage device 204 is a large-capacity internal or external storage unit such as a hard disk drive or a DVD drive, and stores application programs executed by the CPU 201 and various data. In the case of the information processing server A, the above-described DBs 20a to 20c can be stored in the storage device 204. A communication I / F (interface) 205 is a communication device for performing information communication via the network 30a or 30b. The input device 206 is input means such as a keyboard and a mouse. A display 207 is a display unit that displays a processing result of the CPU 201 and the like.

<Processing of Information Processing Server A>
Next, processing executed by the CPU (201) of the information processing server A will be described with reference to FIGS.

  FIG. 4A is a flowchart showing processing at the time of receiving usage information and updating the usage information DB 20a. S <b> 1 is processing of the toll booth terminal 10, and transmits usage information of the user 102 to the information processing server A. The toll booth terminal 10 transmits usage information to the information processing server A in real time or periodically (daily, weekly, etc.) when the user 102 passes the toll booth.

  In S10, the information processing server A receives usage information from the toll gate terminal 10 via the network 30a. In S12, the information processing server A updates the usage information DB 20a according to the usage information received in S10. As a result, the latest usage information of each user 102 is accumulated in the usage information DB 20a.

  Next, FIG. 4B is a flowchart showing processing at the time of setting the acquisition right of carbon dioxide emission rights of each user 102 and updating the acquisition right information DB 20b. In S21, it is determined whether or not it is processing timing such as acquisition right setting. Processing related to setting acquisition rights, etc. is performed periodically (monthly, annually, etc.). In S22, based on the usage information stored in the usage information DB 20a, the right to acquire carbon dioxide emission rights is set for each user according to the usage of the expressway using the ETC system. In S23, the acquisition right information DB 20b is updated based on the acquisition right set in S22.

  There are several ways to set the acquisition rights. Basically, it is desirable to set in proportion to the travel distance of the expressway. This is because, when traveling on a highway for a longer distance, it is considered that carbon dioxide emissions are reduced than when traveling on a general road for the same distance.

  As the simplest setting method, the acquisition right is set in proportion to the highway usage fee. This is because the usage fee may vary depending on the expressway even if the same mileage is used, but generally depends on the mileage. In this case, for example, the acquisition right is calculated by setting a usage fee per 1 ton of the acquisition right.

  As another setting method, a travel distance is calculated from an entrance toll gate and an exit toll gate, and an acquisition right is set in proportion to the calculated travel distance. In this case, the distance traveled between each toll booth can be calculated more easily by creating a database in advance. When passing through the toll gate only once, as in the case of the Metropolitan Expressway, it is simulated by the average mileage.

  In setting the acquisition right, the model of the car can be taken into account. For example, in the case of a large vehicle such as a truck, it is considered that the amount of carbon dioxide emission reduction is greater when traveling on a highway than when traveling on a general road than when traveling on an ordinary vehicle. Therefore, more acquisition rights can be set for large vehicles.

  Next, FIG. 5 is a flowchart showing processing at the time of transfer of carbon dioxide emission rights from the carbon dioxide fixing company 104 to the user 102. In S31, it is determined whether or not it is processing timing. The transfer of carbon dioxide emission rights is carried out regularly (annual units, etc.). In S32, based on the acquisition right information accumulated in the acquisition right information DB 20b and the emission right information accumulated in the emission right information DB 20c, the carbon dioxide fixing company 104 that transfers the carbon dioxide emission right, and the use of which the right is transferred The matching process for determining the person 102 and the amount of transfer is performed. Transfer of carbon dioxide emission rights is established by the establishment of matching. Details will be described later.

  In S33, the acquisition right information DB 20b and the emission right information DB 20c are updated based on the result of the matching process in S32. Specifically, according to the transferred carbon dioxide emission right, the acquisition right of the user 102 who has transferred it from the acquisition right information DB 20b is subtracted, and the carbon dioxide of the carbon dioxide fixing company 104 of the carbon dioxide fixing company 104 is subtracted from the emission right information DB 20c. Subtract emission credits. Through these processes, trading of carbon dioxide emission rights is automated and can be performed smoothly.

  In S34, a carbon dioxide fixation business in which carbon dioxide emission rights are transferred from the deposit account 103a in which at least part of the usage fee of the ETC system paid by the user 102 is deposited to the deposit management server 50 via the network 30b. A notice of a transfer instruction of the consideration is transmitted to the deposit account of the person 104. The deposit management server 50 that has received this notification accesses the deposit management server (51) that manages the deposit account of the carbon dioxide fixing company 104 to which the consideration is transferred, and performs the consideration transfer procedure. As a result, the carbon dioxide fixing company 104 obtains a price. Operation is facilitated because transaction costs are settled automatically.

  In S35, a notification that the carbon dioxide emission right has been transferred is sent to the terminal 41 of the carbon dioxide fixing company 104 as the transferor and the terminal 40 of the user 102 as the transferee by e-mail. This allows the parties to know that there has been a transfer of carbon dioxide emission rights. Instead of e-mail, the information processing server A may be accessed by the parties from the terminals 40 and 41 to provide information indicating that the transfer has been performed. Thus, one unit of processing is completed.

  Next, the matching process in S32 will be described in detail. Basically, the carbon dioxide emission rights accumulated in the emission right information DB 20c are allocated according to the amount of acquisition right (in this embodiment, ton) of each user 102 accumulated in the acquisition right information DB 20b. It will be. When the total amount of carbon dioxide emission rights is smaller than the total amount of acquisition rights, for example, the carbon dioxide emission rights are allocated according to the ratio of the amount of acquisition rights of each user 102 to the total amount of acquisition rights. For example, if the total amount of acquisition rights is 200 tons and the total amount of carbon dioxide emission rights is 100 tons, the user 102 who has the acquisition right of 10 tons will obtain 5 tons of carbon dioxide emission rights. Alternatively, priority can be set for each user 102 by giving priority to the one with a large amount of acquisition rights, and carbon dioxide emission rights can be assigned to the users 102 with higher priority.

  On the contrary, when the total amount of carbon dioxide emission rights is larger than the total amount of acquisition rights, for example, the transfer of the carbon dioxide emission rights of the difference between them can be carried over to the next time. Alternatively, the carbon dioxide emission right is allocated according to the ratio of the amount of acquisition right of each user 102 to the total amount of acquisition right. For example, when the total amount of acquisition rights is 100 tons and the total amount of carbon dioxide emission rights is 200 tons, the user 102 who has the acquisition right of 10 tons will obtain the carbon dioxide emission right of 20 tons. Alternatively, priority is given to each carbon dioxide fixing company 104 by giving priority to the one with a large amount of carbon dioxide emission rights, and the carbon dioxide emission rights of the carbon dioxide fixing company 104 with higher priority are set. You may make it give priority to transfer.

  Further, the carbon dioxide fixing company 104 may be able to set the unit price of its own carbon dioxide emission right. This unit price information can be stored in the emission right information DB 20c, for example. Then, the carbon dioxide emission right of the carbon dioxide fixation company 104 set at a low unit price may be preferentially transferred. The carbon dioxide fixing company 104 that has set the unit price at a low price can obtain the price more reliably, although the price is reduced.

Second Embodiment
In the above-described embodiment, the highway management organization 100 manages a series of processes, but some of them can be performed by another person. Here, a case where an intermediary manages processes related to carbon dioxide emission rights transactions will be described.

Hereinafter, differences from the example of FIG. 1 will be described.

  In the case of this embodiment, the broker 200 exists and the broker 200 performs a carbon dioxide emission right transaction. The highway management organization 100 only provides the highway usage information using the ETC system of each user 102 to the broker 200, and the broker 200 performs other processing.

  Next, a system for smoothly managing the transaction mechanism of the second embodiment will be described. FIG. 7 is a block diagram of a transaction system according to the second embodiment of the present invention. Hereinafter, differences from the example of FIG. 2 will be described.

  In the case of the present embodiment, a usage information totaling server B and an intermediary server C are provided instead of the information processing server A. The usage information totaling server B is managed by the highway management organization 100, and is connected to a large number of toll gate terminals 10 deployed on various highways via the network 30a. Collect and aggregate. The usage information is transmitted to the broker server C via the network 30b. The broker server C is managed by the broker 200 and includes a usage information DB 20a, an acquisition right information DB 20b, and an emission right information DB 20c. The user terminal 40, the carbon dioxide fixing company terminal 41, and the deposit management server 50 and 51 can communicate with each other via the network 30b. The configurations of the usage information totaling server B and the broker server C are the same as those shown in FIG.

  The processing executed by the broker server C is basically the same as the processing of the information processing server A shown in FIGS. However, in the usage information reception shown in FIG. 4A, the usage information is received from the usage information totaling server B instead of the toll terminal 10. The broker server C can receive the usage information periodically (weekly, monthly, etc.). Other processes are the same as those of the information processing server A. In the present embodiment, the presence of the broker 200 can reduce the burden on the highway management organization 100.
