Description

  The present invention relates to an apparatus and a method related to trading of carbon dioxide emission rights, and in particular, to a company that desires allocation of carbon dioxide emission rights, a carbon dioxide absorption forest area calculation device for calculating a forest area to be allocated, and It relates to the same method.

  Since carbon dioxide has a strong absorption band in the infrared wavelength band, it is widely known to have a function as a so-called greenhouse gas that prevents heat from the ground from diffusing into the universe. In recent years, the concentration of carbon dioxide in the air has increased abnormally, and global warming caused by this has become one of the serious environmental problems. The largest cause of the increase in the concentration of carbon dioxide in the air is said to be the large consumption of fossil fuels such as oil, but the decrease in forest area due to excessive logging (so-called deforestation) is also significant. It is said to be the cause. In order to deal with this problem, the Kyoto Protocol concluded in 1997 has set the reduction target for each country of greenhouse gas emissions including carbon dioxide.

  There are a variety of methods for reducing greenhouse gas emissions, and one of them is drawing attention to methods that utilize the carbon dioxide absorption capacity of forests. That is, forest trees absorb carbon dioxide in the air by photosynthesis and release oxygen. Carbohydrates produced by photosynthesis are fixed in the form of carbon in trees and used for tree growth. It is said that Japan's forests absorb and fix about 20% of carbon dioxide emissions from energy consumption nationwide. Therefore, in order to reduce greenhouse gas emissions, it is effective to increase the carbon dioxide absorption capacity of the forest itself. To this end, the decrease in the forest area is stopped and this is increased. It is important to maintain and nurture forests for this purpose, and forest development projects such as tree planting are being promoted.

  As a method for reducing greenhouse gas emissions, a method that is drawing attention together with the above is a method of directly incorporating the carbon dioxide absorption capacity of forests into the process itself for achieving the reduction target. In other words, when a company that wants to achieve a reduction target by purchasing the carbon dioxide absorption capacity of a forest from a forest owner purchases an amount of carbon dioxide emission right that matches the carbon dioxide absorption capacity, the company Is counted as the achievement of the reduction target. Such a mechanism is recognized as a mechanism called “Kyoto Mechanism” in the Kyoto Protocol.

  Several mechanisms have already been proposed to enable such carbon dioxide emission trading. For example, in Patent Document 1, a carbon dioxide emission right of an unspecified plant in a CDM project site (which refers to a land on which a plant capable of fixing carbon dioxide released into the atmosphere is vegetated) is calculated and calculated. A carbon dioxide emission trading system for trading the carbon dioxide emission rights through the Internet is disclosed. This trading system is a database that stores basic data (the basic data includes aerial data obtained by photographing the surface of the ground including the CDM business location, and the amount of chlorophyll in a measurement location in the CDM business location measured at the same time as this photography. Based on basic data such as data indicating the sunshine hours of the CDM business site within a predetermined period, and data indicating the light intensity of the CDM business site measured at the same time as the above shooting) And a management server connected to a plurality of client computers via the Internet via the server. The client's computer is a computer that participates in the carbon dioxide emission trading system. To calculate and store the company's emissions, apply for the purchase of carbon dioxide emission, and receive a notification of the completion of the transaction. It is what you use.

Specifically, trading of emission credits using this system is performed in the following procedure.
First, when the client accesses the management server via the Internet, the management server displays a usage screen on the client. On this usage screen, the client confirms whether or not to use this system (if there is an intention to use, for example, an application button is pressed).
Clients are classified into four types depending on whether they have a carbon dioxide restriction frame or a CMD business location. For this reason, client information is transmitted from the client server to the management server.
Therefore, trading between clients of emission rights is performed using the absorption amount and emission amount of the client calculated based on the above calculation method. For example, trading of emissions credits is performed between a client with emissions exceeding the regulatory limit and a client with a certain amount of absorption that can be sold and has a CMD business location. (See Patent Document 1).

  The carbon dioxide emission trading system is used as one of the measures to reduce greenhouse gas emissions. However, the carbon dioxide absorption capacity of forests is another measure to reduce greenhouse gas emissions. It can be said that the effectiveness of the project will not be improved if it is addressed separately or unrelated to the forest development project, including afforestation to improve itself. Because carbon dioxide emissions trading itself does not physically reduce the global carbon dioxide emissions, it merely reduces the amount commensurate with the carbon dioxide absorption capacity of the forest. This is because an effective measure can only be achieved if the carbon absorption capacity itself is improved. Even if only a carbon dioxide emission trading system is developed with the reduction of the forest area neglected without giving any consideration to forest growth and maintenance projects such as afforestation, carbon dioxide will eventually be absorbed due to the limitations of the carbon dioxide absorption capacity of the forest. Clearly, the setting of emission credits will also be limited, and such trading systems will not stand. Therefore, it is important to link the carbon dioxide emission trading system with forest development projects such as afforestation.

  However, in the conventional transaction system including Patent Document 1, no consideration is given to interlocking with the forest cultivation and maintenance business, and the system has not been effective.

  In addition, the carbon dioxide emission trading system is used as part of efforts to address the environmental issue of global warming as one of the measures to reduce greenhouse gas emissions. This approach to environmental issues is an urgent issue on a global scale, especially for companies that have a heavy social responsibility and whose management status is largely influenced by their social image. In addition to this, it is natural to actually address the problem seriously, but in addition to this, it is extremely important to appeal to society that we are seriously addressing environmental issues.

  To this end, the CO2 emission trading system is designed to inform society that companies are actively striving to achieve greenhouse gas emission reduction targets by purchasing carbon dioxide emission rights. It is important to be able to appeal. In particular, it is effective to be able to make this appeal in a concretely visible form, and as an appealing method for that purpose, for example, using images of forests that are subject to purchased carbon dioxide emission rights, `` Our company It is conceivable that PR will be carried out using media such as homepages, TVs, pamphlets, etc., "The amount of carbon dioxide emissions reduced by the amount of carbon dioxide that can be absorbed by this forest has been reduced." For this purpose, it is necessary that the forest for which emission credits are set at the time of trading is specified as a specific section. Because, once a forest parcel to be traded has been identified, companies can hold exclusive rights to that forest parcel (although sharing the same forest parcel allowance is not prevented) This is because “this forest” can be specified and used for PR.

  In addition, companies can appeal to society positively for environmental issues by using the purchase price of carbon dioxide emission credits for forest development projects. It is effective to be able to make this appeal in a concretely visible form, and as an appealing method for this purpose, the video is used in the same way. It may be possible to conduct PR such as “It was used for expenses”. For this purpose, it is necessary that the purchase price for carbon dioxide emission credits is always linked to the cost of the forest development project. It is desirable that a forest parcel is identified.

  However, in the conventional transaction system including Patent Document 1, the forest section that is the target of carbon dioxide emission rights is not specified, and the allocated amount of carbon dioxide emission is merely specified. For this reason, it was not possible to carry out PR activities using images of forests that were subject to purchased carbon dioxide emission rights. In addition, as for the use of the purchase price, as mentioned above, since there is no consideration for linking the carbon dioxide emission trading system with the forest development project, there are many things that do not consider the use of the purchase price. It was not possible to carry out PR activities using the images of forests where the development and maintenance business was conducted using the purchase price. Patent Document 1 discloses a mechanism that can appeal how the emission right assigned by the assigner himself / herself contributes to society by designating the purpose of use. However, this scheme cannot be used by PR purchasers for PR activities. In addition, as an example of the purpose of charity, as in the case of charitable projects, the carbon dioxide emission trading system should be linked to the forest development project as part of efforts to address global warming. Because there was no idea that this was the case, it was not possible to appeal in a visible way that companies were contributing to forest development by purchasing carbon dioxide emission rights.

Therefore, the problem to be solved by the present invention is that the company is actively striving to achieve the reduction target of greenhouse gas emissions by purchasing carbon dioxide emission rights. In order to make it possible to realize a carbon dioxide emission management system that can be appealed in a visible manner, a mechanism is provided to identify the forest for which emission credits are set as a specific division at the time of trading. There is.
At the same time, it is linked to the purchase price to be used for the cost of the forest development project, and it is clearly visible that the company contributes to forest development by purchasing carbon dioxide emission rights. To provide a mechanism for identifying specific forests that are the target of forest development projects using the purchase price in order to realize a carbon dioxide emission management system that can be appealed in It is in.

  In order to solve the above-described problems, the first invention includes an absorption capacity map holding unit that holds an absorption capacity map that displays a carbon dioxide absorption capacity of a forest in a size per unit area of a forest on a map, and a company Based on the desired allocation amount acquisition unit that accepts the input of the desired allocation amount that is the carbon dioxide emission right that is desired to be allocated, and calculates the forest parcel on the map to be allocated to the company based on the acquired desired allocation amount and the absorption capacity map A forest section calculation device for absorbing carbon dioxide is provided.

  The third invention is based on the first or second invention, and the absorption capacity map holding unit further determines the price of carbon dioxide emission trading according to the area on the map where the carbon dioxide absorption capacity is indicated. The compensation table holding means for holding the compensation table is calculated, and the compensation of the carbon dioxide emission right according to the forest section calculated by the forest section calculation unit is calculated according to the consideration table held in the consideration table holding means. A carbon dioxide absorbing forest section calculation device further including a price calculation section is provided.

  In addition, the fourth invention is based on the third invention, and holds a training price map that holds a training price map that displays the amount of money necessary for afforestation or forest growth in the size per unit area on the map A section on the map that should be invested in afforestation or forest development according to the acquisition price of carbon dioxide emissions paid by the company based on the consideration calculated by the department and the consideration calculation section and the cultivation consideration map A carbon dioxide absorbing forest section calculating device further comprising a calculating unit.

  In addition, the fifth invention includes an absorption capacity map holding step for holding an absorption capacity map in which the carbon dioxide absorption capacity of a forest is displayed in a size per unit area of the forest on the map, and the carbon dioxide that the company desires to allocate.

With the present invention, it is clearly visible to society that companies are actively striving to achieve greenhouse gas emission reduction targets by purchasing carbon dioxide emission rights. In order to make it possible to realize a carbon dioxide emission right management system that can be used, it is possible to provide a mechanism for specifying a forest for which emission rights are set as a specific section at the time of trading.
At the same time, the purchase price will be linked to the cost of the forest development project, and the company will contribute to forest development by purchasing carbon dioxide emission rights.

  Examples of the present invention will be described below. The relationship between the embodiments and the claims is as follows. The first embodiment mainly relates to claims 1, 3, 4, and 5, and the second embodiment mainly relates to claim 2. In addition, this invention is not limited to these Examples at all, and can be implemented in various modes without departing from the gist thereof.

  <Overview>

  In the present embodiment, the carbon dioxide absorption forest section calculation device (hereinafter sometimes simply referred to as “forest section calculation device”) uses a forest that is subject to emission right setting as a specific section when trading carbon dioxide emission rights. It is an apparatus having a mechanism for specifying. In addition, a device having a mechanism for identifying a forest that is a target of a forest nurturing and maintenance project using a purchase price as a specific section is also included in the apparatus of this embodiment.

  <Configuration>

    (General)

  First, the general configuration of the carbon dioxide absorbing forest section calculating apparatus according to the present invention will be described.

  FIG. 1 is a conceptual diagram showing an example of a general configuration of a carbon dioxide absorbing forest section calculating apparatus according to the present invention. As shown in the figure, the “carbon dioxide absorption forest partition calculation device” 0100 according to the present invention includes an “absorption capacity map holding unit” 0110, an “assignment desired amount acquisition unit” 0120, and a “forest partition calculation unit”. 0130. In addition, as shown in the figure, the forest partition device according to the present invention may have a “compensation calculation unit” 0140, and in addition to this, a “cultivation compensation map holding unit” 0150 and “cultivation” You may have the division calculation part "0160.

  Details of the configuration of each unit in the system will be described later, and the general concept of the system will be described here.

  In the example of this figure, it is assumed that the following situation exists as an element outside the configuration of the system according to the present invention.

  First, there is a forest owner 0102 who owns the forest 0101. There are typically multiple forest owners. Forest owners can be national, local governments, businesses, or individuals.

  On the other hand, a company 0103 exists. This company is a company that emits carbon dioxide during business execution and has a target to reduce greenhouse gas emissions.

  The company will make efforts to achieve greenhouse gas emission reduction targets through self-help efforts such as conversion of fuel for operation and improvement of machinery, while carbon dioxide in forests cannot be covered by this alone. Suppose you want to compensate by receiving an allocation of carbon dioxide emission rights that matches your absorption capacity.

  Therefore, in order to meet the needs of such enterprises, there is a carbon dioxide emission trading system that includes forest owner subscribers and enterprise subscribers as constituent members. Such a transaction system itself can be realized by using a known technique as disclosed in Patent Document 1 described above, for example.

  In this case, the company wants to make a concrete and visible appeal to society that it is actively striving to achieve the greenhouse gas emission reduction target by purchasing carbon dioxide emission rights. Therefore, we would like to conduct PR using the images of forests that are subject to purchased carbon dioxide emission rights on our website and TV commercials. For this purpose, it is necessary to specifically identify the forest parcels that are subject to the purchased carbon dioxide emission rights.

  Therefore, the “carbon dioxide absorbing forest section calculating device” 0100 of the present invention identifies such forest sections with the following configuration.

First, the “absorption capacity map holding unit” 0110 holds an absorption capacity map 0111 that displays the carbon dioxide absorption capacity of the forests owned by the forest owners who are subscribers as the size per unit area of the forest on the map. To do. The carbon dioxide absorption capacity of forests is generally expressed in tons of carbon per year (tC / year) and can be obtained using known techniques. For example, the amount of growth per unit area (for example, 1 ha) of forest (unit: m ³ ) minus the amount of felled forest (unit: m ³ ) is multiplied by predetermined factors such as carbon content and volume density Is required.

  In the absorption capacity map, the carbon dioxide absorption capacity is displayed as a size per unit area of forest on the map. For example, the carbon dioxide absorption capacity per ha of a 5 ha forest located in XX town XX town, Hokkaido, is 1.2 t-C / year. The absorption capacity map holding unit holds the carbon dioxide absorption capacity per unit area of forest as data covering every forest section for all the forests that are subject to the setting of the carbon dioxide emission trading system using this device. .

  On the other hand, a subscriber company that wishes to allocate carbon dioxide emission rights inputs the desired allocation amount to, for example, a local terminal device of a forest section calculation device installed in the company. For example, when the company A wishes to allocate 6 tons of carbon dioxide emission rights per year, the numerical value is input. The “assignment desired amount acquisition unit” 0120 receives this input and acquires the desired assignment amount 0121 of the company.

  Next, the “forest section calculation unit” 0130 calculates the forest section 0131 on the map to be allocated to the company based on the acquired desired allocation amount and the absorption capacity map. To put it simply, it identifies the location on the map where the forest parcels are subject to the company's carbon footprint.

  For example, when the desired allocation amount of a company is 6 t / year as in the above-described example, a forest section having a carbon dioxide absorption capacity corresponding to this is searched from the data held in the absorption capacity map, For example, since the carbon dioxide absorption capacity of a 5 ha forest located in XX town XX town, Hokkaido, is exactly 6 t-C / year, this is specified as an emission right setting target. When there are a plurality of forest sections that can be set, it is desirable to calculate so that the forest sections do not become enclaves as much as possible. This is in view of convenience when a company uses the image of the forest section for PR.

  If there is a matter desired by the company other than the allocated amount, the forest section may be specified in consideration of such matter. For example, when a company desires a forest block near the company's location or trade area, the forest block at such a location may be specified.

  In addition, the carbon dioxide absorption capacity of forests can vary depending on the age of the tree, the type of tree, the environment of the habitat, etc. even in the same area. For example, in the case of conifers such as larch, todomatsu, cedar, etc., trees in the growing period of 15 to 25 years are said to have the highest absorption rate. Also, as a difference depending on the type of tree, cedar is said to have higher absorption capacity than larch and todomatsu, while larch shows outstanding absorption capacity at around 15 years of age, and this tree age is higher than cedar and todomatsu. Absorption capacity is indicated (the absorption capacity of cedar and todomatsu is about 3.5 t-C / year per ha, whereas that of larch is about 5.5 t-C / year per ha). Needless to say, even in the same kind of trees of the same age, there may be a difference in absorption capacity depending on the environment of the habitat (sunlight, soil condition, etc.). Therefore, for companies that wish to use a vast forest for their images, the type and age of such trees can be specified, such as identifying forest plots with relatively low carbon dioxide absorption per unit area. You may make it specify, considering etc.

  As described above, since the forest section that is the target for setting the carbon dioxide emission right can be specified, the company can use the image of the forest section for PR.

  In addition, in the case of having the “consideration calculation unit” 0140, the unit calculates the carbon dioxide emission right consideration 0141 according to the forest section calculated by the forest section calculation unit. For this calculation, the absorption capacity map holding unit holds a consideration table 0142 in which the consideration for the carbon dioxide emission trading is determined according to the area on the map where the carbon dioxide absorption capacity is indicated. The consideration is calculated.

  In addition to this, in the case of having a “Growth Consideration Map Holding Unit” 0150 and a “Growth Section Calculation Unit” 0160, the amount of money necessary for the planting consideration map holding unit to be planted or forested per unit area on the map Afforestation consideration map 0151 displayed in the size of the plant, and afforestation according to the consideration calculated by the consideration calculation unit by the cultivation section calculation unit and the acquisition consideration of the carbon dioxide emission right paid by the company by the cultivation consideration map Alternatively, the section 0161 on the map to be invested in forest growth is calculated.

  As a result, the purchase price of carbon dioxide emission credits is used in the forest development project, so that the company can appeal to society for its proactive approach to environmental issues, and will be subject to the setting of carbon dioxide emission rights. Since the forest section can be specified, the company can use the image of the forest section for PR regarding the contribution.

    (Configuration of each part)

  Based on the above, the specific configuration of each part will be described in detail next.

  FIG. 2 is a diagram illustrating an example of functional blocks of the carbon dioxide absorbing forest section calculation device according to the present embodiment. As shown in the figure, the “carbon dioxide absorption forest section calculation device” 0200 includes an “absorption capacity map holding unit” 0210, an “allocation desired amount acquisition unit” 0220, and a “forest partition calculation unit” 0230. .

        (Absorption capacity map holding part)

  The “absorption capacity map holding unit” is configured to hold the absorption capacity map 0211. The “absorption capacity map” refers to a display of the carbon dioxide absorption capacity of a forest in the size per unit area of the forest on the map.

The carbon dioxide absorption capacity of forests can be obtained using known techniques. As described above, the carbon dioxide absorption capacity of forests is generally expressed in tons of carbon per year (tC / year). For example, the amount of growth per unit area (for example, 1 ha) of forest (unit: m ³ ) minus the amount of felled forest (unit: m ³ ) is multiplied by predetermined factors such as carbon content and volume density Is required.

  “Display by the size per forest unit area on the map” means that the geographical location (address, latitude / longitude, etc.) where the forest is located is related to the amount of absorption per unit area (eg 1 ha) of the forest. It means displaying. The specific amount of forest land absorbed can be found by actually conducting a field survey and measuring it using the above formulas. The above-mentioned example of “the carbon dioxide absorption capacity per ha of the 5 ha forest located in Hokkaido XX County XX Town XX is 1.2-C / year” is an example of such a display. is there.

  In the absorption capacity map, the carbon dioxide absorption capacity displayed in the size per unit area of the forest on the map is the forest for which carbon dioxide emission rights are set in the carbon dioxide emission trading system using this device. All are covered by forest section. Here, the “forest section” is a group of forests that can be set as one carbon dioxide emission right, and is typically a forest that exists in a state that does not become an enclave for the same owner. Forests that belong to the same owner are because it is easy to conclude a CO2 emission right setting contract. Forests that do not become enclaves are used for the convenience of video. Because. In a group of forests that do not become enclaves for the same owner, if the type of tree, age, habitat environment, etc. are uniform, simply measure the total amount of absorption of the entire forest, The amount of absorption per area can be calculated by conducting a sample survey on some plots, etc., but if the type of tree etc. is different, measure each unit area closely and measure each unit area. What is necessary is just to obtain | require the amount of absorption. For example, in the case of “5ha forest located in Hokkaido XX County XX Town XX” in the above example, this forest section is classified from Section A to Section E (this section is fine). It is possible to display the amount of absorption based on the measurement for each section.

  FIG. 3 is a diagram illustrating an example of an absorption capacity map. Also in this figure, the address, area, and absorption capacity (whole forest, per unit area) for each forest are distinguished and described together with the forest identification number. As shown for “001”, the forest may be displayed as a whole if it is a uniform forest. In this case, the absorption capacity per unit area is obtained by dividing the absorption capacity of the entire forest by the area of the forest. Value. On the other hand, “002” is a case where the kind of trees and the like are different as described above, and the amount of absorption for each unit area is displayed by finely measuring each unit area. The absorption capacity map may be summarized in a table as shown in the example of this figure, or the absorption capacity may be added to the forest developed on the map or displayed in different colors. Good. Thereby, for example, when determining whether or not it is an enclave, a search according to the attribute of the absorption capacity map becomes possible.

    (Desired acquisition unit)

  Returning to FIG. 2, the “desired allocation amount acquisition unit” is configured to receive an input of the allocation allocation amount 0221. The “allocation desired amount” is a carbon dioxide emission right that the company desires to allocate, and is generally expressed in carbon tons (tC / year).

  For example, the requested allocation amount can be received by the administrator of the device connected via the Internet, with the desired allocation amount entered using a mouse, keyboard, etc. at a user terminal installed in the company. This is done by accepting it at the installed server.

  FIG. 4 is a diagram illustrating an example of information indicating the desired allocation amount. In this example, the carbon dioxide emission rights that the company A desires to allocate are shown in an XML (extensible Markup Language) type format. Note that the format of the information indicating the desired allocation amount is not limited to the XML format, and may be another format. In the example of this figure, regarding the desired allocation amount information desired by company A, along with the desired allocation amount, the desired forest land location considering the company's location, trade area, etc., and the forest considering the appearance when used in the video An example is shown in which information indicating the desired partition area is included.

    (Forest section calculation unit)

  Returning to FIG. 2 again, the “forest section calculation unit” is configured to calculate the forest section 0231 on the map to be allocated to the company based on the acquired desired allocation amount and the absorption capacity map.

  Specifically, when receiving the input of the desired allocation amount from the company, the forest section calculation unit detects the carbon dioxide absorption capacity corresponding to the desired allocation amount included therein by searching the absorption capacity map. When the carbon dioxide absorption capacity corresponding to the desired allocation amount is detected, the forest section having the carbon dioxide absorption capacity is specified as the forest section on the map to be allocated to the company. The calculation performed by the forest section calculation unit is to specify the forest section on the map to be assigned in this way. In the calculation (specification), it is desirable to calculate so that the forest section is not as enclave as possible. The reason for this is that when the calculated forest division for which the carbon dioxide emission right is set is used for the PR video, it can be displayed as a group of forests.

  FIG. 5 is a diagram showing a specific example of the calculation procedure of the forest section on the map to be allocated to the company based on the acquired desired allocation amount and the absorption capacity map.

  In the example of this figure, first, the forest section calculation unit reads the desired allocation amount (in this example, “6t-C / year”) (S0501). Next, the forest section calculation unit searches for a forest section having an absorption capacity (in this example, “6t-C / year”) that matches the desired allocation amount with reference to the absorption capacity map (S0502). As a result, it is assumed that (1) forest 001 and (2) a combination of forests 002A and 002E are detected (S0503) (this example shows an example in which only two forests are detected for convenience of explanation) However, more forests will actually be detected). Therefore, the forest section calculation unit specifies one forest from the plurality of detected forests according to a predetermined condition (S0504). For example, in the example of this figure, there is a condition that the enclave is excluded as much as possible, and the forest of (2) is an enclave, so the case where the forest of (1) is detected corresponds. In addition, when a predetermined condition is not set, you may make it identify at random (random).

  With such a configuration, it becomes possible to specify the forest for which the emission right is set as a specific division in the carbon dioxide emission trading, and the company can use the image of the forest division for PR activities. it can.

  In addition, as mentioned above, it is desirable to search under the condition that the forest section is not as enclave as possible. This is due to the convenience when used as an image. For this reason, the forest section calculation device may have means for excluding the enclave. An example having such means will be described in another embodiment.

    (Configuration with means to determine the price of carbon dioxide emissions trading)

  Next, a description will be given of a configuration in which the carbon dioxide-absorbing forest section calculation device according to the present embodiment has means for determining a price for carbon dioxide emission trading.

  FIG. 6 is a diagram illustrating an example of a functional block of the carbon dioxide absorption forest section calculation apparatus according to the present embodiment, and illustrates an example having means for determining a price for such carbon dioxide emission trading.
