[0016] Hereinafter, the embodiments of the present disclosure will be described in detail with reference to the drawings. The following description of the preferred embodiments is merely illustrative in nature and is not intended to limit the present invention, its application, or its uses.

[0017] The management device, management method, and management program according to the present disclosure are realized as a part or all of the management system according to the present embodiment.

[0018] In addition, the management system according to this embodiment is used by various organizations such as companies, groups, and local governments to achieve their own GHG emission reduction targets on an organizational, product, project, and other units.

[0019] (First embodiment) Fig. 1 is a block diagram showing the configuration of a management system according to the first embodiment. As shown in Fig. 1, the management system includes a server device 1. The server device 1 is configured to be able to communicate with an operation terminal 2 via a communication network N.

[0020] The operation terminal 2 (reception unit) is a PC, a smartphone, or the like, and is a terminal operated by a user (an employee or a user of an organization, etc.). The operation terminal 2 includes a display unit 21 and an operation unit 22. The display unit 21 is composed of a monitor or the like, and displays images to the user in response to instructions from the control unit of the operation terminal 2. The operation unit 22 is composed of input devices such as a keyboard and a mouse, and accepts operations from the user. Also, a management program is pre-installed in the memory unit of the operation terminal 2. The control unit of the operation terminal 2 operates each unit of the operation terminal 2 in accordance with the management program.

[0021] As will be described later in detail, the operation terminal 2 receives input from the user to set a target value for GHG emission. Specifically, the operation terminal 2 receives a selection of a scenario from the user in order to set a target value of GHG emission. Note that the target value of GHG emission may be set without receiving a selection of a scenario from the user.

[0022] As mentioned above, in recent years, climate change issues have arisen due to the large amount of GHG emissions such as carbon dioxide. In order to take measures to prevent, mitigate, and adapt to this climate change, governments and international organizations are calling on organizations (users) to reduce GHG emissions. Examples of initiatives to reduce GHG emissions, the calculation and reporting of GHG emissions that are linked to these, and frameworks for disclosing climate change-related information include the Science-Based Targets Initiative (SBTi), Cisco Discovery Protocol (CDP), RE100, Task Force on Climate-related Financial Disclosures (TCFD), and the GHG Protocol. These initiatives aim to In order to minimize the impact of climate change, GHG emission targets and various standards and rules have been established for each organization, product, project, etc. In this embodiment, the organization sets the GHG emission target value according to the TCFD scenario analysis. The TCFD scenario analysis assumes and analyzes scenarios of how climate change and long-term policy trends to address it will change the business environment, and considers how such changes will affect the business strategy of the organization. For example, there are multiple scenarios (2°C rise scenario, 4°C rise scenario, etc.) used in the TCFD scenario analysis according to the average temperature rise forecast. In the TCFD scenario analysis, the organization sets goals and indicators regarding climate-related risks and opportunities in each of these multiple scenarios. Note that the GHG emission target value can be set without accepting the selection of a scenario from the user. In this embodiment, the operation terminal 2 accepts the selection of which scenario of the TCFD scenario analysis to set the GHG emission target value according to from the user.

[0023] The operation terminal 2 transmits to the server device 1 information indicating the operation input received by the operation unit 22 from the user.

[0024] (Configuration of server device 1) As shown in FIG. 1, the server device 1 includes a communication unit 11, a storage unit 12, and a control unit 13.

[0025] The communication unit 11 is configured with, for example, an electric circuit, and communicates with the operation terminal 2 via the communication network N.

[0026] The storage unit 12 includes a ROM (Read Only Memory), a RAM (Random Access Memory), a HDD The storage unit 12 is a storage medium configured by a hard disk drive (D) and a solid state drive (SSD), etc. The storage unit 12 stores various programs executed by the control unit 13.

[0027] Moreover, various databases are configured in the storage unit 12 (scenario registration unit). Specifically, the storage unit 12 stores a scenario DB and an investment destination DB.

[0028] The scenario DB is a database of scenarios that show predictions for future climate change, and is used by users to select scenarios to be used in TCFD scenario analysis, etc. Specifically, it contains multiple scenarios used in TCFD scenario analysis (transition scenarios such as IEA NZE 2050, IEA B2DS, IEA 2DS, IEA 450, IEA SDS, IEA APS, IEA STEPS, and IEA CPS, and climate scenarios such as RCP 1.9, RCP 2.6, RCP 3.4, RCP 4.5, RCP 6.0, RCP 7.0, and RCP 8.5). Scenarios including the above scenarios (hereinafter referred to as the "2°C rise scenario, 4°C rise scenario, etc.) are stored (registered).

[0029] The investment DB is a database used by users to select investment destinations (see Figure 2). Specifically, the investment DB associates the investment destination name (investment target) with values ​​indicating the user's contribution in each asset class, such as asset class and investment price, the denominator value used to calculate GHG emissions for each asset class, GHG emissions, and GHG emissions in Scope 3 Category 15 of the GHG Protocol. The investment destination name (investment target) is data indicating the names of organizations (company names and project names) in which an organization can invest. The asset class is data indicating which class the corresponding investment target falls into among the asset classes defined in the PCAF described later. For example, in Figure 2, the investment price (A) is data indicating the price at which an investment is made in the corresponding investment target. The denominator (B) is data indicating the corporate value, such as the market capitalization of the investment target. The emissions (C) are data indicating the GHG emissions of the corresponding investment target. The emissions in Scope 3 Category 15 of the GHG Protocol are data indicating the GHG emissions when the investment price is invested in the corresponding investment target. Emissions in Scope 3, Category 15 of the GHG Protocol are calculated as A x C ÷ B.

[0030] The GHG Protocol's Scope 3 Category 15 "Investment" requires that the contribution of the GHG emissions of the investment to the company be calculated and reported. The calculation standard for GHG emissions from investments, mainly for financial institutions, is set by PCAF (Partnership for Carbon Accounting Financials). The standard specifies the calculation of GHG emissions for six asset classes: listed stocks and corporate bonds, business loans and unlisted stocks, project finance, commercial real estate, housing loans, and auto loans. In this embodiment, investments in projects are mainly assumed, but investments in other asset classes may also be possible. For this reason, for example, an organization can reduce the investor's Scope 3 Category 15 GHG emissions by changing the investment destination from the current investment destination to an investment destination with lower GHG emissions.

[0031] The control unit 13 includes, for example, a CPU (Central Processing Unit) and a semiconductor memory. The control unit 13 controls each unit of the server device 1 by executing the programs stored in the storage unit 12.

[0032] The control unit 13 also includes a setting unit 131 , an emission amount calculation unit 132 , a required reduction amount calculation unit 133 , a selection unit 134 , and a carbon price calculation unit 135 .

[0033] The setting unit 131 sets a target value of GHG emission. In the first embodiment, the setting unit 131 accepts a selection of a scenario from a user through the operation terminal 2. Then, the setting unit 131 sets a target value of GHG emission in the future (for example, one year later, two years later, five years later, ten years later, thirty years later, or 2025, 2030, 2040, 2050, etc.) based on the scenario accepted from the user. That is, the setting unit 131 sets a target value of GHG emission from the present onward based on the scenario accepted from the user. Specifically, there are a 40% reduction in GHG emission from a base year (for example, 2015) in 2030, a net zero GHG emission in 2040 (a total of the organization's GHG emission and GHG removal amount is zero), and the like.

[0034] The emission calculation unit 132 (acquisition unit) calculates the GHG emission amount. For example, the emission calculation unit 132 calculates various GHG emission amounts by organization, product, project, etc., based on the power generation facilities owned by the organization and the production volume of products. The calculation target of GHG emission amounts (organizational scope and activity scope) may be set in advance by master registration, etc. Then, for each GHG emission source included in the organizational scope and activity scope, each GHG emission amount may be calculated from data input by accepting the input of direct measurement results of GHG emission amounts and accepting the input of numerical values ​​(activity amount, emission coefficient, various quantities, etc.) used to calculate each GHG emission amount, and the GHG emission amount of the organization may be calculated as the sum of these. GHG emission amounts may also be calculated by calculating the amount of GHG emission per product handled by the organization. This may include GHG emissions calculated for each product or service (product unit) or GHG emissions calculated for each project. Note that an organization's GHG emissions also include Scope 3 Category 15 GHG emissions (GHG emissions from investments) and GHG emissions from other companies in the supply chain.

[0035] The required reduction calculation unit 133 calculates a required reduction amount of GHG emissions necessary to achieve the target value of GHG emissions set by the setting unit 131. Specifically, the required reduction calculation unit 133 calculates the required reduction amount of GHG emissions by subtracting the GHG emissions of the organization calculated by the emission calculation unit 132 from the target value of GHG emissions set by the setting unit 131. Note that the required reduction amount calculated by the required reduction calculation unit 133 in the first embodiment corresponds to the required activity reduction amount.

[0036] The activity reduction requirement may be expressed as the amount of GHG emissions to be reduced when GHG emissions are directly measured in the activity that emits GHG, or as the amount of activity to be reduced or the emission factor to be reduced when GHG emissions are indirectly calculated by activity amount x emission factor, etc. For example, if the amount of electricity used in the calculation is 1000 kWh, the activity reduction requirement may be expressed as the amount of 200 kWh of the electricity usage 1000 kWh that needs to be reduced. The activity reduction requirement may also be expressed as another activity amount that replaces the activity amount used in the calculation. For example, if the amount of electricity used in the calculation is 1000 kWh, the activity reduction requirement may be expressed as 200 kWh of renewable energy that does not emit GHGs out of the electricity usage 1000 kWh. The activity reduction requirement may also be expressed as a recommendation of an alternative for the activity amount used in the calculation. For example, if the electricity usage used in the calculation is 1000 kWh due to the use of device A, the activity reduction requirement may be expressed as a recommendation to use device B, which uses less electricity than device A. Furthermore, the activity reduction requirement may be expressed as the amount of reduction in the emission coefficient (e.g., 0.0003 t-CO2 / kWh, reduced from the initial 0.0008 t-CO2 / kWh) multiplied by the electricity usage of 1000 kWh used in the calculation.

[0037] The selection unit 134 selects an investment destination corresponding to the required reduction amount of GHG emissions calculated by the required reduction amount calculation unit 133 from among the investment destinations included in the investment destination DB. Specifically, the required reduction amount calculation unit 133 reads out the investment destination DB and selects an investment destination corresponding to the required reduction amount of GHG emissions. For example, it is assumed that the user (organization) has invested in a specific investment target I (company or project) in advance. In this case, the GHG emissions of the user include the GHG emissions due to the investment in the investment target I as the scope 3 category 15. At this time, the selection unit 134 selects an investment destination with less GHG emissions than the investment target I from among the investment destinations registered in the investment destination DB. For example, if the GHG emissions due to the investment in the investment target I are 1000t and the reduction activity amount of the organization is 500t, the selection unit 134 selects an investment destination (investment destination) with GHG emissions of 500t or less in the scope 3 category 15 from the investment destination DB. In this way, the selection unit 134 achieves the required reduction amount of the organization (user). The selection unit 134 may select a plurality of investment destinations. In this case, if the total value of the GHG reduction amount exceeds the required reduction amount of GHG emissions, the plurality of investment destinations may be selected. That is, the selection unit 134 may select one or more investment destinations. The selection unit 134 may accept a change regarding each investment target. For example, in the above-mentioned investment target I, a reduction in the investment price sufficient to achieve the required reduction amount may be accepted. The above-mentioned selection and change acceptance by the selection unit 134 may be performed by accepting a selection instruction from a user. The above-mentioned selection and change acceptance by the selection unit 134 may be performed automatically based on a rule (for example, the investment destination with the lowest investment price among the investment destinations in which the GHG reduction amount exceeds the required reduction amount) that is predetermined to achieve the required reduction amount. The selection unit 134 in the first embodiment corresponds to the first selection unit.

[0038] In the first embodiment, as described above, the investment destination DB stores data indicating an investment destination capable of reducing GHG emissions. That is, the selection unit 134 selects an investment destination from the investment destination DB and accepts changes to the investment details so as to achieve the target value of GHG emissions.

[0039] The carbon price calculation unit 135 calculates the carbon price by applying a predetermined pricing to the GHG emissions of the organization. The carbon price may be a carbon tax imposed as a tax by a national or local government on an organization such as a company or an organization, or an internal carbon tax voluntarily set by an organization such as a company or an organization on GHG emissions. The carbon price may be set as the price of an emission allowance to be purchased for GHG emissions exceeding a cap set for the organization in emissions trading, or may be a price according to a pricing scheme for GHG emissions such as credit trading, carbon border adjustment measures, or other. The pricing may be any pricing method that calculates the carbon price, and may be, for example, an amount per metric ton of GHG emissions (for example, 10,000 yen per metric ton), or may be an average, maximum, minimum, median, or other statistical amount of prices indicated in market transactions, bilateral transactions, etc. related to GHG emissions. The carbon price calculation unit 135 calculates the carbon price from the GHG emissions of the organization calculated by the emission calculation unit 132 according to one or a combination of the above-mentioned predetermined pricing methods. This allows the organization to easily calculate the carbon price and to grasp the cost impact of GHG emissions. As described above, the organization can reduce GHG emissions by investing in the investment destination. The carbon price calculation unit 135 calculates the carbon price when the organization reduces GHG emissions by investing in the investment destination. That is, the carbon price calculation unit 135 calculates the carbon price related to the investment by applying a predetermined price to the GHG emission reduction amount by the investment destination selected by the selection unit 134. The carbon price calculation unit 135 in the first embodiment corresponds to the first carbon price calculation unit. In addition, when the carbon price varies from year to year, the carbon price calculation unit 135 calculates the carbon price according to the year in which the investment is made. The carbon tax may be a tax levied on the carbon content of fossil fuels such as coal and oil.

[0040] (Regarding the operation of the management system) Fig. 3 and Fig. 4 are flowcharts showing the operation of the management creation system according to the first embodiment. Specifically, Fig. 3 shows the overall operation of the management system, and Fig. 4 shows the operation of the management system in the first process (step S21) of Fig. 3.

[0041] When the operation terminal 2 receives an instruction to set a reduction target for GHG emissions from a user via the operation unit 22, the operation terminal 2 requests the server device 1 for a scenario DB. When the server device 1 receives a request for the scenario DB from the operation terminal 2, the server device 1 transmits data contained in the scenario DB to the operation terminal 2. When the operation terminal 2 receives the data from the server device 1, the operation terminal 2 displays a list of scenarios (2°C rise scenario, 4°C rise scenario, etc.) contained in the scenario DB on the display unit 21. The list of scenarios may be displayed in a categorized manner according to how much the global temperature will rise in a specific year if the scenario is selected, such as less than 1.5 degrees, 1.5 degrees or more but less than 2 degrees, 2 degrees or more but less than 3 degrees, 3 degrees or more but less than 4 degrees, and 4 degrees or more. In addition, the list of scenarios may display the scenarios that are selected most frequently for each industry, topography and weather of the location of the head office, factory, etc., and other categories at the top. When the operation terminal 2 receives a selection of a scenario from a user via the operation unit 22, the operation terminal 2 transmits data indicating the selected scenario to the server device 1.

[0042] The setting unit 131 of the server device 1 receives data indicating a scenario selected by a user from the operation terminal 2 (step S1), and executes a first process (step S21).

[0043] In step S21, first, the setting unit 131 sets a target value for future GHG emissions (step S2). The emission calculation unit 132 of the server device 1 calculates the GHG emissions (step S3). For example, the emission calculation unit 132 calculates the GHG emissions based on the power generation facilities owned by the organization, the production volume of products, and the like.

[0044] The required reduction calculation unit 133 of the server device 1 calculates the required reduction amount of GHG emissions necessary to achieve the reduction target set by the setting unit 131 (step S4). Specifically, the required reduction calculation unit 133 calculates the required reduction amount of GHG emissions by subtracting the GHG emissions calculated by the emission amount calculation unit 132 from the target value of GHG emissions set by the setting unit 131.

[0045] The selection unit 134 of the server device 1 reads out the investment destination DB (step S5). Then, the selection unit 134 selects an investment destination corresponding to the required reduction amount of GHG emission calculated by the required reduction amount calculation unit 133 from among the investment destinations included in the investment destination DB (step S6). The selection unit 134 transmits data indicating the selected investment destination to the operation terminal 2, and receives permission to determine the investment destination from the user (step S7).

[0046] The carbon price calculation unit 135 of the server device 1 calculates the carbon price for the reduction of the GHG emissions when the organization invests in the investment target (step S8). The carbon price calculation unit 135 transmits data indicating the calculated carbon price to the operation terminal 2 and causes the display unit 21 to display the data.

[0047] With the above configuration, the management device according to the first embodiment includes an emission calculation unit 132 (acquisition unit) that calculates (acquires) the GHG emission amount, a setting unit 131 that sets a target value of the GHG emission amount, and a required reduction calculation unit 133 that calculates a required reduction amount of GHG emission amount required to achieve the target value of the GHG emission amount. That is, based on the GHG emission amount calculated by the emission calculation unit 132 and the target value of the GHG emission amount set by the setting unit 131, the required reduction calculation unit 133 calculates a required reduction amount of GHG emission amount required to achieve the target value of the GHG emission amount, so that the user (organization) can know the required reduction amount of GHG emission amount required to achieve the target value of the GHG emission amount. This makes it easier for the user to achieve the target value of the GHG emission amount.

[0048] Furthermore, the setting unit 131 sets a target value for future GHG emissions. The selection unit 134 selects an investment destination so as to achieve the target value for GHG emissions. This makes it easier for the user to achieve the target value for GHG emissions.

[0049] (Modification) In the above embodiment, the selection unit 134 achieved the GHG emission target by changing (selecting) the investment destination, but in this modified example, the selection unit 134 may achieve the GHG emission target by changing (selecting) a business partner (supply chain business partner) in the organization's supply chain.

[0050] For example, the storage unit 12 stores the supply chain business partner DB of FIG. 5 together with or instead of the investment destination DB. The supply chain business partner DB is a database used by the user to select a supply chain business partner. Specifically, the supply chain business partner DB associates the name of a supply chain business partner with the transaction target, the amount of activity related to the transaction, the GHG emission coefficient according to the activity of the transaction, the GHG emission amount, the transaction price, and the like. The supply chain business partner name is data indicating the name of an organization (company name or project name) with which an organization can do business. The transaction target is data indicating the name of a product, part, material, or service with which an organization can do business, or other activities that are the subject of a transaction. The activity amount is data indicating the amount of activity related to the corresponding supply chain The data indicates the amount of activity related to transactions with supply chain trading partners. The emission coefficient is a GHG emission coefficient according to the activity of the corresponding supply chain trading partner in the transaction. The emission amount is the GHG emission amount generated by the corresponding transaction. For example, the emission amount is calculated by multiplying the activity amount by the emission coefficient. The transaction price is the transaction price per unit of the trading object. Note that although not shown in this figure, the quantity of the trading object, the activity amount per unit of the trading object, the emission coefficient per unit of the trading object, the emission amount per unit of the trading object, etc. may be included.

[0051] According to the GHG Protocol, when an organization (user) trades (e.g., purchases) a product, the GHG emissions generated by the manufacturing, transport, etc. of the traded product are included in the GHG emissions of the organization. For this reason, for example, an organization can reduce its GHG emissions by changing its trading partner (a trading partner on the supply chain) of the product from the current supply chain trading partner to a supply chain trading partner that can manufacture, transport, etc. the product with less GHG emissions. In addition, an organization can reduce GHG emissions by reducing the amount of trading (amount of activity) even with the same supply chain trading partner. In addition, an organization can reduce GHG emissions by setting a lower emission factor for the trading partner even with the same supply chain trading partner (for example, the supply chain trading partner performs the trading (activity) with a lower emission factor than before through self-help efforts). In this embodiment, a reduction in GHG emissions related to these supply chain trading partners can be realized.

[0052] Here, in the above embodiment, the selection unit 134 selects an investment destination corresponding to the required reduction amount of GHG emissions calculated by the required reduction amount calculation unit 133 from among the investment destinations included in the investment destination DB, but in this modified example, the selection unit 134 selects a supply chain business partner corresponding to the required reduction amount of GHG emissions calculated by the required reduction amount calculation unit 133 from among the supply chain business partners included in the supply chain business partner DB and accepts changes to the transaction content. For example, it is assumed that a user (organization) has previously traded a trading object (such as a screw) with a specific supply chain business partner S (a company or a project). In this case, according to the provisions of Scopes 1 to 3, the GHG emissions of the user include GHG emissions resulting from trading the trading object (such as a screw) with the supply chain business partner S (a company or a project). At this time, the selection unit 134 may select a supply chain business partner that can trade the trading object with less GHG emissions than the supply chain business partner S from among the supply chain business partners registered in the supply chain business partner DB. For example, if the GHG emissions of the trading target of supply chain trading partner S are 100 kg and the required reduction amount is 50 kg, the selection unit 134 may select a supply chain trading partner from the supply chain trading partner DB that is the same trading target as the trading target and has a GHG emission amount of 50 kg or less. In this way, the selection unit 134 achieves the required reduction amount of the organization (user). At this time, the selection unit 134 may select multiple supply chain trading partners if the total value of the GHG reduction amounts of the multiple supply chain trading partners exceeds the required reduction amount of GHG emissions. In other words, the selection unit 134 may select one or more supply chain trading partners. The selection unit 134 in this modified example corresponds to the third selection unit.

[0053] According to this modification, the selection unit 134 selects (changes) business partners in the supply chain to achieve the required reduction amount. In this way, the GHG emission reduction target can be achieved by changing business partners in the supply chain. In addition, if data on GHG emissions of not only direct supply chain business partners but also business partners of each supply chain business partner is available, it is possible to grasp the change in GHG emissions when a supply chain business partner is changed.

[0054] Second embodiment The management system according to the first embodiment manages future GHG emission reduction targets. In contrast to this, the management system according to the second embodiment is one that manages the user's current or past GHG emission reduction targets.

[0055] The management system according to the second embodiment has the same configuration as the management system according to the first embodiment (see FIG. 1), but differs in some of the data stored in the memory unit 12 and the functions of the setting unit 131, required reduction amount calculation unit 133, selection unit 134, and carbon price calculation unit 135 of the control unit 13. The carbon price calculation unit 135 of the second embodiment corresponds to a second carbon price calculation unit.

[0056] Specifically, in the second embodiment, a trading partner DB is stored in the storage unit 12 instead of an investment partner DB.

[0057] The business partner DB is a database used by an organization to select a business partner for environmental value (see Figure 6). Specifically, in the business partner DB, the business partner name is associated with the GHG emission reduction method, GHG reduction amount, and transaction price. The business partner name is data indicating the name of the organization (company name or project name) that owns the environmental value that the user can trade. The GHG emission reduction method is data indicating the GHG emission reduction method of the corresponding business partner. The GHG emission reduction method includes a method of reducing the GHG emission of an organization by trading environmental value (offset such as J-credits and environmental certificates), a method of reducing the GHG emission of an organization by constructing a power generation facility using natural energy or by afforestation, investment in negative emission technology (technology that directly reduces carbon) or a long-term project to establish the technology, and a reduction in one's own activity volume and / or emission coefficient. The GHG reduction amount is data indicating the GHG emission amount reduced by the GHG reduction method. The transaction price is the price when trading with the corresponding business partner.

[0058] In the CDP and other initiatives aimed at reducing GHG emissions, an organization is deemed to have reduced its GHG emissions by purchasing environmental value. In addition, by trading with a business partner that constructs power generation facilities using natural energy, the organization's GHG emissions are reduced through additionality. In the second embodiment, the user (organization) aims to achieve a GHG emission reduction target by trading with a business partner.

[0059] The setting unit 131 sets a reduction target of the GHG emission of the user. In the second embodiment, the setting unit 131 accepts a selection of a scenario from the user through the operation terminal 2. Then, the setting unit 131 sets a target value of the GHG emission of the current year or the past year (such as one year ago) based on the scenario accepted from the user. That is, the setting unit 131 sets a target value of the GHG emission of the organization for the current year or the past year (such as one year ago) based on the scenario accepted from the user. Specifically, the setting unit 131 may set a target value of the GHG emission of the organization in the past and store it in a target value storage unit (not shown), and read and set the target value. In addition, the setting unit 131 may set a target such as reducing the GHG emission of the base year (for example, 2015) by 40% in 2030, or achieving net zero GHG emission (the total of the GHG emission and GHG removal of the organization is zero) in 2040, and set the reduction target in the case of uniform reduction by that year to each year. That is, in the second embodiment, similarly to the first embodiment, the setting unit 131 may set a target value of GHG emissions for the organization in the future. Also, the setting unit 131 may set a target value of GHG emissions for the current year or the past year (e.g., one year ago) by receiving an input from a user, not based on a scenario. Also, the setting unit 131 may set the target value by reading out a target value of GHG emissions for the current year or the past year (e.g., one year ago) that was previously set.

[0060] The required reduction amount calculation unit 133 calculates the required reduction amount of GHG emissions necessary to achieve the target value of GHG emissions set by the setting unit 131. The second embodiment calculates the required reduction amount of GHG emissions by subtracting the GHG emissions of the organization calculated by the emission calculation unit 132 from the target value of GHG emissions set by the setting unit 131. Note that the required reduction amount calculated by the required reduction amount calculation unit 133 in the second embodiment corresponds to the required offset reduction amount.

[0061] The selection unit 134 selects a business partner corresponding to the required reduction amount of GHG emissions calculated by the required reduction amount calculation unit 133 from among business partners included in the business partner DB. Specifically, the required reduction amount calculation unit 133 reads out the GHG reduction amount (see FIG. 6) of each business partner from the business partner DB, and selects a business partner corresponding to the required reduction amount of GHG emissions. For example, the selection unit 134 selects a business partner from among business partners registered in the business partner DB such that the GHG reduction amount exceeds the required reduction amount of GHG emissions. For example, in FIG. 6, when the required reduction amount is 20 tons, the selection unit 134 selects Company H as a business partner. At this time, the selection unit 134 may select a plurality of business partners and, if the total value of the GHG reduction amounts exceeds the required reduction amount of GHG emissions by selecting the plurality of business partners, the selection unit 134 may select the plurality of business partners. That is, the selection unit 134 may select one or more business partners. The selection unit 134 in the second embodiment corresponds to the second selection unit.

[0062] In the second embodiment, an organization can offset or reduce GHG emissions in the future by trading (obtaining) environmental value with a business partner registered in the business partner DB. As described above, the business partner DB stores data indicating business partners with which the organization can offset or reduce GHG emissions through trading. That is, the selection unit 134 selects business partners from the business partner DB so as to achieve the target value of GHG emissions.

[0063] The carbon price calculation unit 135 calculates a carbon price for the reduction of GHG emissions when an organization transacts with a business partner. As described above, an organization can offset or reduce GHG emissions by transacting with a business partner. Therefore, the carbon price calculation unit 135 calculates a carbon price when an organization offsets or reduces GHG emissions by transacting with a business partner. The carbon price calculation unit 135 of the second embodiment corresponds to a second carbon price calculation unit.

[0064] (Regarding the operation of the management system) Fig. 7 is a flowchart showing the operation of the management creation system according to the second embodiment. Fig. 7 shows the operation of the management system according to the second embodiment. In Fig. 7, compared with Fig. 3 and Fig. 4, steps S12, S15 to S18 are executed instead of steps S2, S5 to S8.

[0065] When the setting unit 131 of the server device 1 receives data indicating a scenario selected by the user from the operation terminal 2 (step S1), it sets a target value of the GHG emission amount for the current year or the past year of the organization (step S12). Then, steps S3 and S4 are executed. Note that in step S1, the setting unit 131 of the server device 1 does not necessarily need to select a scenario, and may directly accept an input of a target value of the GHG emission amount for the current year or the past year from the user.

[0066] The selection unit 134 of the server device 1 reads out the supplier DB (step S15). Then, the selection unit 134 selects a supplier corresponding to the required GHG emission reduction amount calculated by the required reduction amount calculation unit 133 from among the suppliers included in the supplier DB (step S16). The selection unit 134 transmits data indicating the selected supplier to the operation terminal 2 and receives permission to determine the supplier from the user (step S17).

[0067] The carbon price calculation unit 135 of the server device 1 calculates a carbon price based on the amount of GHG emission reduction through the transaction with the business partner (step S18). The carbon price calculation unit 135 transmits data indicating the calculated carbon price to the operation terminal 2, and causes the display unit 21 to display the data.

[0068] With the above configuration, the management device according to the second embodiment includes an emission calculation unit 132 (acquisition unit) that calculates (acquires) the GHG emission amount, a setting unit 131 that sets a target value of the GHG emission amount, and a required reduction calculation unit 133 that calculates a required reduction amount of GHG emission amount required to achieve the target value of the GHG emission amount. That is, based on the GHG emission amount calculated by the emission calculation unit 132 and the target value of the GHG emission amount set by the setting unit 131, the required reduction calculation unit 133 calculates a required reduction amount of GHG emission amount required to achieve the target value of the GHG emission amount, so that the user (organization) can know the required reduction amount of GHG emission amount required to achieve the target value of the GHG emission amount. This makes it easier for the user to achieve the target value of the GHG emission amount.

[0069] Furthermore, the setting unit 131 sets a target value for the current or past GHG emission amount of the organization. The selection unit 134 selects a business partner so as to achieve the target value for GHG emission amount. This makes it easier for the user to achieve the GHG emission amount target of the organization.

[0070] In step S16 of this embodiment, the selection unit 134 may preferentially select a supplier with a low activity level from the supplier DB when selecting a supplier from the supplier DB. This makes it possible to obtain a trading object (product, etc.) that has been manufactured using a method that generates low GHG emissions.

[0071] In addition, in step S16 of this embodiment, the selection unit 134 may preferentially select a supplier with a smaller emission coefficient from the supplier DB when selecting a supplier from the supplier DB. The emission coefficient is determined by actual measurement, and is also determined as a general emission coefficient for each activity from statistical data such as an input-output table. In general, since the calculation of an emission coefficient from actual measurement is complicated, companies, projects, etc. use substitute values ​​from input-output tables, etc., but the substitute values ​​do not reflect the GHG reduction efforts of the companies, projects, etc. in their activities. For this reason, when the selection unit 134 selects a supplier from the supplier DB, it preferentially selects a supplier with a smaller emission coefficient for the same activity from the supplier DB, which indirectly increases the willingness of the supplier to measure the emission coefficient and reduce GHG emissions.

[0072] (Other embodiments) As described above, the embodiments have been described as examples of the technology disclosed in the present application. However, the technology in the present disclosure is not limited to these, and may be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made as appropriate.

[0073] The organization in the above embodiment may be any organization. For example, the organization may be a country, a local government, a company, an organization, or other group. The organization may also be a business that provides services such as electricity, gas, water, communication lines, insurance, banking, web shopping, teaching knowledge such as education, advertising, logistics, leasing, retail, and product sales such as merchandising. The organization may also be a business that operates in the manufacturing, real estate, retail, finance, or other industries.

[0074] In the first embodiment, a business partner DB may be configured in the storage unit 12. In this case, the selection unit 134 may select business partners from the business partner DB so as to achieve the target value of GHG emissions. The selection unit 134 may also select one or more business partners and one or more investment destinations from the business partner DB and the investment destination DB so as to achieve the target value of GHG emissions.

[0075] In addition, in each of the above embodiments, the selection unit 134 selects an investment destination (transaction destination) in step S7 (S17). However, the selection unit 134 may select an investment destination ( For example, the selection unit 134 may display data stored in the investment destination DB (business destination DB) on the display unit 21 of the operation terminal 2 and accept the selection of an investment destination (business destination) from the user. In this case, the display unit 21 may display the target value of GHG emissions set by the setting unit 131 and the required reduction amount of GHG emissions calculated by the required reduction amount calculation unit 133. In addition, the carbon price calculation unit 135 may display, for each investment destination (business destination), a calculation result of the carbon price to be reduced by making an investment contract (trading contract) with the investment destination (business destination).

[0076] In addition, in each of the above embodiments, the setting unit 131 sets the target value of the GHG emissions of the organization based on the scenario used in the scenario analysis of TCFD, but is not limited to this. For example, the setting unit 131 may set the target value of the GHG emissions of the organization according to the criteria and rules set in the GHG emissions initiatives such as SBTi, CDP, RE100, TCFD, and GHG Protocol. For example, the setting unit 131 may set the target value so that the GHG emissions of the organization are reduced by 2.5% or 4.2% per year according to the setting of the target year such as 5 to 15 years from now and the criteria such as "well below 2 degrees" or "keep below 1.5 degrees". The setting unit 131 may determine which criteria or rules of the initiative to follow by the user's selection. In addition, the setting unit 131 may accept the setting of different targets for multiple periods for the above criteria and rules or the target value of the GHG emissions of the organization arbitrarily set by the user. For example, the setting unit 131 may accept the target value of the organization's GHG emissions as a 3% reduction per year compared to last year until 2030, and a 4% reduction per year compared to last year until 2040.

[0077] Furthermore, the setting unit 131 may set a target value for GHG emissions in another unit instead of or in addition to the target value for GHG emissions of the organization. For example, the setting unit 131 may set a target value for GHG emissions in a product (including service) unit. Furthermore, the setting unit 131 may set a target value for GHG emissions in a base unit linked to the organization. In this embodiment, the numerical values ​​and the like expressed in organizational units in each of the above-mentioned embodiments may be expressed in the other unit.

[0078] Furthermore, the setting unit 131 may calculate a target value of the organization's GHG emissions for each scenario stored in the scenario DB, and display the calculation results on the display unit 21. For example, in a TCFD scenario analysis, it is necessary to evaluate the importance of each risk (such as transition risk or physical risk), and a target value of GHG emissions in each scenario is set based on this evaluation. For this reason, the setting unit 131 may receive an evaluation of the importance of this risk from the user, calculate a target value of the organization's GHG emissions in each scenario, and display the result on the display unit 21.

[0079] Furthermore, in the above-described first embodiment, the selection unit 134 may preferentially select from the investment destination DB (business partner) an investment destination (business partner) that calculates its own emission coefficient. GHG emissions are generally determined based on activity amount x emission coefficient. This emission coefficient can be a general value, but it is also possible for the investment destination (business partner) to calculate it itself. Since it takes time and cost for the investment destination (business partner) to calculate its own emission coefficient, it can be said that such an investment destination is highly conscious of trying to reduce GHG emissions further through investment. For this reason, the selection unit 134 may preferentially select from the investment destination DB (business partner) an investment destination (business partner) that calculates its own emission coefficient.

[0080] In the first embodiment, the selection unit 134 may select an investment destination to achieve a target value based on the investment destination's past GHG emission reduction results. For example, the selection unit 134 may preferentially select an investment destination that has a track record of achieving GHG reduction amounts or power generation amounts registered in the investment destination DB in the past, or may preferentially select an investment destination that has a high achievement track record.

[0081] Furthermore, the emission amount calculation unit 132 may be provided outside the server device 1. Furthermore, the various databases stored in the storage unit 12 may be provided outside.

[0082] Furthermore, in each of the above embodiments, the carbon price calculation unit 135 calculates the carbon price after step S7 (or step S17), but this is not limited to this. For example, the carbon price calculation unit 135 may calculate the carbon price after the required reduction calculation unit 133 calculates the required reduction. In this case, the carbon price calculation unit 135 calculates the carbon price of the organization when the required reduction is calculated.

[0083] In addition, in each of the above embodiments, when the selection unit 134 selects an investment destination (a business partner or a business partner in the supply chain), it may establish a contract between the organization and the investment destination (the business partner or a business partner in the supply chain) and notify the user and the investment destination (the business partner or a business partner in the supply chain) of the establishment of the investment contract.

[0084] Further, a management program for realizing the functions according to the above-described embodiment is installed in each of the server device 1 and the operation terminal 2. The server device 1 and the operation terminal 2 execute the management program to realize various functions according to the above-described embodiment.

[0085] Furthermore, the management system in the second embodiment may show (display on the display unit 21) that the reduction was not only offset but also offset after energy creation (in-house), energy saving, and energy collection (buying power sources, discharging from storage batteries, surplus energy from cogeneration systems, etc.). This may show that the reduction was not achieved by greenwashing only through offsetting. [Industrial Applicability]

[0086] The management system according to the present embodiment is useful because it calculates the required reduction in GHG emissions required to achieve the organization's GHG emission target value. [Explanation of symbols]
