[0010] (Background to this disclosure) Before describing the present disclosure, the background to the present disclosure will be described with reference to Fig. 1. Fig. 1 is a schematic diagram showing a decarbonization system used in the embodiments described below.

[0011] In recent years, greenhouse gas emissions have increased dramatically due to human social activities, causing global warming. Measures to reduce greenhouse gas emissions, primarily carbon dioxide, are urgently needed.

[0012] The Paris Agreement, adopted at the 2015 United Nations Framework Convention on Climate Change Conference of the Parties (COP21) and coming into effect in 2016, was an international agreement to achieve "net zero" (a state in which greenhouse gas emissions and removals are balanced) by 2050. Carbon credits are attracting attention as one of the means to achieve this net zero goal.

[0013] Carbon credits are a system in which companies and other organizations issue credits representing the reduction (amount reduced or absorbed) of greenhouse gases such as carbon dioxide (CO2) produced by forest protection or afforestation, or the introduction of energy-saving equipment, and can then trade these credits with other organizations such as other companies. Organizations are the entities that create carbon credits, and other companies are the entities that use them. Carbon credit systems include the government-led (Japan) J-Credit and the private-sector-led Voluntary Credit.

[0014] Here, examples of organizations include companies, businesses, organizations, local governments (e.g., local governments), and non-profit organizations (NPOs) that are working to contribute to the environment, but they may also be any other organization that is working to contribute to the environment.

[0015] Furthermore, greenhouse gas emissions reductions are being sought not only from organizations such as those mentioned above, but also from users such as individuals and households. However, currently, it is difficult for users to effectively utilize the environmental value generated by their decarbonization actions for purposes such as creating carbon credits. Furthermore, currently, the environmental value generated by users' decarbonization actions is small, making it difficult to make it a viable business. It is believed that decarbonization can be accelerated if users and organizations work together toward decarbonization, but as mentioned above, currently, an environment in which users and organizations can work together toward decarbonization has not been created.

[0016] Therefore, the inventors of the present application developed the decarbonization system (an example of an environmental system) described below with the aim of accelerating decarbonization by fostering momentum among users and organizations working toward decarbonization. This environmental system is characterized by the fact that environmental value generated by users' environmental actions can be exchanged for rebate menus offered by organizations (providers). The environmental system also uses environmental points as a medium for exchanging environmental value and rebate menus. Environmental points are a general term for points used within the environmental system, and there can be one or more (e.g., multiple) types. Rebate menus are the objects of exchange that can be exchanged for environmental value.

[0017] The decarbonization system is an example of an environmental system for reducing greenhouse gas emissions, and is a system for mainly reducing carbon dioxide emissions. For example, the environmental system may include a system for reducing CO2 emissions, a system for reducing greenhouse gas emissions other than CO2, or a system for other purposes than reducing greenhouse gas emissions.

[0018] In the following, decarbonization points refer to environmental points that include those obtained through actions other than decarbonization, and include points obtained through reducing CO2 emissions, points obtained through reducing greenhouse gas emissions other than CO2, and points obtained through actions other than reducing greenhouse gas emissions.

[0019] Furthermore, decarbonization points are an example of environmental points awarded for the above-mentioned environmental actions.

[0020] An overview of a system according to one embodiment of the present invention will be described below. Hereinafter, as an example of an environmental system for reducing greenhouse gas emissions, a decarbonization system for primarily reducing emissions of carbon dioxide, which is considered to have a large impact on global warming among greenhouse gases, will be described. Hereinafter, organizations participating in the decarbonization system (i.e., organizations offering rebate programs) will also be referred to as providers.

[0021] The outline of the decarbonization system described below is merely an example, and is not limited to the content described below. For example, the decarbonization system will be described below as an example realized via an app, but is not limited to this. For example, the decarbonization system may be realized as a function provided in a home energy management system (HEMS) owned by a household, a terminal device such as an intercom, or a virtual private assistant (VPA) device such as a smart speaker with a monitor. A smart speaker is a speaker with an AI (artificial intelligence) assistant function that supports interactive voice operation.

[0022] A user selects a decarbonization action menu containing a desired decarbonization action from a decarbonization action menu list containing multiple decarbonization action menus via a decarbonization application (app) for realizing a decarbonization system. Specifically, the app is installed on a terminal device owned by the user, and the decarbonization action menu list is displayed on the terminal device. The user operates the terminal device to select a decarbonization action menu containing a desired decarbonization action from the displayed decarbonization action menu list. The decarbonization action menu associates the type of decarbonization action, the unit time for performing the decarbonization action, information indicating the provider, the type of points (type of decarbonization points) earned by the decarbonization action, and the number of decarbonization points awarded for the amount of decarbonization action performed. For example, the user can check the multiple decarbonization actions displayed on the app and information regarding the awarded decarbonization points and select a decarbonization action to be performed. Note that there are multiple point types corresponding to the decarbonization action menu, i.e., the type of decarbonization action, as will be described later using Figure 4.

[0023] The unit time for performing decarbonization actions is a time period set for counting (aggregating) the amount of CO2 reduction, the number of decarbonization actions, the duration of the decarbonization actions, the distance decarbonized, etc. The unit time is set in advance, and examples include, but are not limited to, one day, one week, one month, one year, etc. For example, decarbonization points may be awarded for each unit time according to the amount of decarbonization action taken in that unit time.

[0024] In this way, the decarbonization action menu sets how many points of each type can be earned by performing each decarbonization action. The decarbonization action selected determines whether the decarbonization points awarded to the user are linked to carbon credits. For example, the decarbonization action selected may determine whether the decarbonization points awarded to the user are automatically linked to J-Credits derived from renewable energy electricity, energy-saving J-Credits, voluntary credits rather than J-Credits, or points that cannot be converted into credits at all. Furthermore, since providing a point type for each environmentally contributing corporation would result in too many point types, the point type may include one or more decarbonization points that can only be used in conjunction with an environmentally contributing corporation, i.e., are not compatible with each other and have limited redemption options.

[0025] The decarbonization action menu list may include a decarbonization action menu including decarbonization actions set by the app administrator, or may include a decarbonization action menu including decarbonization actions proposed by providers or users participating in the decarbonization system (for example, a decarbonization action menu set by an environmental contribution corporation). Also, one decarbonization action menu may include two or more decarbonization actions.

[0026] In addition, information about the provider's environmental contribution efforts may be displayed on the terminal device along with the provider's proposed decarbonization actions. In this way, the app allows users to view the provider's environmental contribution efforts within the app. This increases the provider's opportunities to inform users of its organization's environmental contribution or decarbonization efforts, thereby helping to create a sense of environmental contribution among users through these efforts. Furthermore, by posting information about how the provider utilized the emission reductions generated by users who exchanged their points, users can feel a connection with the provider or its brand, products, or services (e.g., characters, idols, etc.), which may increase customer engagement. Furthermore, these efforts can help create a sense of environmental contribution among stakeholders surrounding the provider, such as investors, business partners, and job seekers, in addition to customers, thereby increasing corporate value.

[0027] Note that the decarbonization actions taken by the user are not limited to those included in the decarbonization action menu, and may be, for example, decarbonization actions proposed by the user. They may also be decarbonization actions voluntarily proposed by the user within the app and approved by a provider or app administrator. In this case, the approved provider or administrator will award the user decarbonization points.

[0028] In this specification, decarbonization behavior is an example of environmental behavior related to greenhouse gas emission reduction, and mainly refers to CO2 emission reduction behavior. Furthermore, for example, environmental behavior may include behavior to reduce CO2 emissions, behavior to reduce greenhouse gas emissions other than carbon dioxide, or behavior other than greenhouse gas emission reduction (e.g., environmental contribution behavior described below, behavior to indirectly reduce greenhouse gases, etc.). Greenhouse gases other than carbon dioxide may include, for example, greenhouse gases whose reduction amount is converted into CO2.

[0029] Environmental actions may include actions to reduce greenhouse gases other than carbon dioxide, such as methane, nitrous oxide, and alternative fluorocarbons, and may also include actions to reduce greenhouse gases whose reductions are not converted into CO2 (not quantified).

[0030] Environmental actions may be actions that directly reduce greenhouse gas emissions, such as those described above, or actions that indirectly reduce greenhouse gas emissions, such as purchasing products with a low carbon footprint or alleviating the tightness of electricity supply and demand (for example, participating in DR (Demand Response)).

[0031] CO2 reductions include both quantifiable and unquantifiable CO2 reductions. When a user selects a decarbonization action, the app monitors the amount of CO2 reductions equivalent to the unquantifiable CO2 reductions. The app then awards the user decarbonization points based on the amount of CO2 reductions. Decarbonization points can be exchanged for rewards offered by various providers. Rebate options can be viewed at any time. Users select the desired reward option from a decarbonization catalog containing multiple reward options offered by various providers via the app. This allows the user to use the decarbonization points accumulated through decarbonization actions. Exchanging decarbonization points for reward options is equivalent to exchanging the reward option for the environmental value generated by the decarbonization action corresponding to the decarbonization points. The amount equivalent to CO2 reductions refers to the number of decarbonization actions that cannot be quantified as CO2 reductions, the duration of the decarbonization action, the distance traveled, and other factors. The amount equivalent to CO2 reductions is determined based on the decarbonization action, not limited to duration or distance, and is determined based on the decarbonization action that cannot be quantified as CO2 reductions.

[0032] In addition to the rebate menu offered by the provider, information regarding the provider's environmental contribution efforts may also be displayed on the terminal device.

[0033] The timing for presenting the provider's environmental contribution efforts to the user within the app may be the first timing when the user selects the decarbonization action as described above, or the second timing when the user selects the rebate menu. The presentation timing may be any timing between the first timing and the second timing, for example.

[0034] The app administrator then applies to an examination agency for the amount of CO2 reduction equivalent to the exchanged decarbonization points. If the application is approved, the amount of CO2 reduction is exchanged for J-Credits. In other words, J-Credits are issued according to the amount of CO2 reduction. These J-Credits are awarded to the companies that offer the rebate menu. This allows companies to acquire J-Credits, which are environmental value according to the decarbonization points.

[0035] In addition, when decarbonization points are exchanged for a rebate menu in the decarbonization system, the provider is required to pay a fee based on the number of decarbonization points, a fee based on the number of exchanges, etc. to the administrator of the decarbonization system.

[0036] There are multiple types of environmental value that providers want to obtain. Therefore, the decarbonization action menu must also be categorized according to the type of environmental value. Furthermore, multiple types of intermediary points that connect the classified decarbonization actions with the type of environmental value that providers want to obtain are also required.

[0037] Therefore, in the embodiment, we will explain a point-granting system that makes it easy for a provider (here, an organization) that offers users an environmental value rebate menu to encourage users to take the environmental actions (here, decarbonization actions) they desire.

[0038] <Configuration> A point-giving system 10 according to an embodiment will be described below with reference to the drawings. FIG. 2 is a block diagram showing a decarbonization system 1 including the point-giving system 10 according to the embodiment. In the embodiment, the decarbonization system 1 is realized by a server device. Note that the decarbonization system 1 is not limited to a server device, and may also be realized by an information terminal such as a smartphone, a tablet terminal, a HEMS, or a personal computer.

[0039] As shown in FIG. 2, the decarbonization system 1 is capable of communicating, via a network such as the Internet, between a terminal device 20 used by a user and a management server 3 used by a provider who is making efforts to contribute to the environment. Note that in the example shown in FIG. 2, one terminal device 20 and one management server 3 are illustrated, but in reality, there are as many terminal devices 20 as there are users who use the decarbonization system 1. Note that if the decarbonization system 1 is realized by a HEMS, there will be as many terminal devices 20 as there are households that use the decarbonization system 1. Furthermore, there may actually be as many management servers 3 as there are providers who use the decarbonization system 1. In the embodiment, the terminal device 20 is a smartphone, but it may also be a tablet terminal, a personal computer, or the like.

[0040] The decarbonization system 1 acts as an intermediary between users and providers who are making efforts to contribute to the environment, encouraging users to take decarbonization actions while also making users aware of the providers' efforts to contribute to the environment. For the main functions of the decarbonization system 1, please refer to the above-mentioned <Overview>. The decarbonization system 1 has multiple functions, one of which is the point-granting system 10.

[0041] The point-granting system 10 is a system for granting points to users who have taken decarbonization actions, in accordance with the actions. Here, points are virtual currency paid out in accordance with the decarbonization actions taken by the user. The number of points granted to a user increases or decreases depending on the degree to which the user has taken the decarbonization action, for example, the amount of CO2 emissions reduced by the decarbonization action. Specifically, the greater the amount of CO2 emissions reduced by the decarbonization action, the greater the number of points granted to the user. Points can be used to exchange for rebate menus offered by providers.

[0042] The number of points awarded to a user not only increases or decreases depending on the amount of CO2 emissions reduced through decarbonization actions (CO2 emission reduction amount), but also on the value of the CO2 emission reduction amount. For example, if the amount of CO2 emissions reduced through decarbonization actions is 1 kg, the number of points awarded to a user will be different if the market value of the CO2 emission reduction amount is 3,000 yen or 6,000 yen.

[0043] Furthermore, the number of points awarded to a user may increase or decrease not only depending on the amount of CO2 emissions reduced by the decarbonization actions, but also depending on the degree of implementation of decarbonization actions that cannot be converted into CO2 emission reductions. For example, the number of points awarded to a user may increase or decrease depending on the number of decarbonization actions taken or the period over which the decarbonization actions were taken.

[0044] The rebate menu offered by the provider may be, for example, a product or service. For example, the provider may offer to the user, as a rebate menu, a highly rare product or service that can only be obtained by taking decarbonization action. Note that highly rare products or services also include items that are not available on the market and cannot normally be exchanged, such as a baseball signed by a major league baseball player. Of course, the provider may offer to the user, as a rebate menu, general products or services, regardless of whether they are rare or not.

[0045] The return menu may also include the donation of environmental value to the provider or an organization other than the provider, without requiring any goods or services in return.

[0046] 1, the point-giving system 10 includes an acquisition unit 11, a calculation unit 12, an awarding unit 13, a presentation unit 14, and a storage unit 15. Note that the point-giving system 10 may include at least the acquisition unit 11, the calculation unit 12, and the awarding unit 13, and may not include the presentation unit 14 and the storage unit 15.

[0047] The processing unit including the acquisition unit 11, the calculation unit 12, the assignment unit 13, and the presentation unit 14 is realized by, for example, a processor or a dedicated circuit. The processing unit realizes various functions by hardware such as a processor executing a computer program (software) stored in the storage unit 15. The computer program may be stored in a memory provided in the hardware. In the embodiment, the processing unit has, as functional components, the acquisition unit 11, the calculation unit 12, the assignment unit 13, and the presentation unit 14.

[0048] The acquisition unit 11 acquires reduction information including the type of environmental action (here, decarbonization action) related to the reduction of greenhouse gas (here, CO2) emissions selected by the user. Furthermore, the acquisition unit 11 refers to a table linking each decarbonization action menu with a point type stored in the storage unit 15, which will be described later, and acquires the point type corresponding to the decarbonization action menu when acquiring the reduction information. The acquisition unit 11 acquires the reduction information, for example, by receiving the reduction information input to the terminal device 20 by the user operating the terminal device 20 from the terminal device 20 via a network.

[0049] FIG. 3 is a diagram showing an example of a decarbonization action menu list. For example, when a user wants to acquire points or perform a decarbonization action, the user operates the terminal device 20 to access the decarbonization system 1. Then, the user selects a decarbonization action menu including the decarbonization action they want to perform from the decarbonization action menu list displayed on the display 200 of the terminal device 20 as shown in FIG. 3. This enables the acquisition unit 11 to acquire reduction information. Then, the user actually performs the decarbonization action included in the selected decarbonization action menu. Here, the decarbonization action menu list is a list of multiple items A1, each of which indicates one or more providers' environmental contribution efforts and decarbonization actions. Item A1 indicates, for example, the provider's environmental contribution efforts, the decarbonization action desired by the provider, and the points and type of points that can be obtained by the decarbonization action.

[0050] The acquisition unit 11 may acquire reduction information based on a self-report of the decarbonization action taken by the user. The self-report may be performed, for example, by the user operating the terminal device 20 and freely inputting the details of the decarbonization action taken, or by selecting details corresponding to the decarbonization action taken from a pre-prepared list for self-reporting. The pre-prepared list for self-reporting may also present the user's decarbonization action estimated from information acquired by a sensor or the like. For example, the user operates the terminal device 20 to input the details of the self-report indicating that the selected decarbonization action has been taken. This allows the acquisition unit 11 to acquire the reduction information.

[0051] For example, a user may operate the terminal device 20 to self-report that they used a home appliance such as a dishwasher during a time period when solar power generation was relatively high. A user may also self-report that they reduced the time they spent playing video games by playing outside, for example. A user may also self-report that they have taken decarbonization actions by operating the terminal device 20 to upload an image of a meter reading slip showing the amount of water, gas, or electricity used. A user may also self-report that they have taken decarbonization actions by operating the terminal device 20 to upload an image of a screen displayed on a monitoring device that monitors the status of solar power generation, for example.

[0052] Acquisition unit 11 may execute a process to confirm whether the content of the self-report input by the user is correct. For example, if acquisition unit 11 indicates that the dishwasher was operated during a time period when the amount of power generated by solar power generation is relatively high, acquisition unit 11 may confirm whether the dishwasher was operated during that time period by referring to the dishwasher's operation history. If acquisition unit 11 confirms that the content of the self-report is correct, acquisition unit 11 may acquire reduction information based on the self-report, and if it confirms that the content of the self-report is incorrect, acquisition unit 11 may discard the reduction information based on the self-report.

[0053] The acquisition unit 11 may also acquire reduction information by means other than self-reporting, rather than relying on the user's self-reporting that they have implemented decarbonization behavior. For example, the acquisition unit 11 may receive data transmitted from a monitoring device linked to the user via a network and acquire reduction information based on the received data. The monitoring device may include, for example, a management device used in an energy management system such as a HEMS, a smart meter, an IoT (Internet of Things) device, a smartphone, etc. The reduction information may also be acquired from sensors built into these monitoring devices or external sensors (such as a window open / close sensor or a temperature / humidity sensor). The acquisition unit 11 receives data indicating, for example, the amount of gas or electricity used by the user, the operating status of home appliances, or home facilities from a management device. The acquisition unit 11 also receives data indicating, for example, the amount of gas or electricity used from a smart meter. The acquisition unit 11 also receives data indicating, for example, the operating status of home appliances or home facilities from an IoT device.

[0054] "Data" here may include CO2 emissions, CO2 emission reductions, energy consumption, and the amount of energy consumption reduced, specifically the amount of electricity, gas, and kerosene used or not used, and the duration, distance, and number of times energy-consuming devices and equipment were used or not used. "Data" may also include the operating status of devices, devices, equipment other than devices in the home, types of bicycles, or automobiles, etc.

[0055] The calculation unit 12 calculates the number of points for each type of point acquired by the acquisition unit 11 based on the environmental actions performed by the user. In an embodiment, the calculation unit 12 calculates the number of points for each point type to be awarded to a user or a group based on the type of decarbonization action menu performed, the monitoring results of the decarbonization action performed, various coefficients, the selling price of environmental value, the point type corresponding to the decarbonization action menu performed, and the like acquired by the acquisition unit 11 or stored in the memory unit 15. Here, the unit constituting the group may be in various forms, such as a family unit sharing a household, a group based on relationships between users both inside and outside the game, a group with common attributes, belonging to an area under the jurisdiction of a power transmission and distribution company, a neighborhood association or other local community, a group supporting a specific provider, a group grouped by a provider, a group grouped by an administrator, a randomly formed group, a group belonging to a local government such as a city, ward, town, village, or prefecture, or all users participating in the decarbonization application or game system.

[0056] In addition, the calculation unit 12 calculates a new point balance for each point type by adding the number of points for each point type newly awarded by the above calculation to the point balance for each point type in the point account that stores the points of the user or group acquired by the acquisition unit 11 or stored in the memory unit 15.

[0057] FIG. 4 is a diagram showing an example of a correlation table between decarbonization actions and point types. In FIG. 4, "origin" indicates the type of decarbonization action from which the point type is derived, and "provider's gain" indicates the carbon credits, data, or results of the action obtained by the decarbonization action taken by the user. Also, in FIG. 4, "monitoring method" indicates the method for monitoring decarbonization actions, and "monetization" indicates the manner of monetization by the provider or the customer for the provider. Note that FIG. 4 does not show data indicating how many points can be earned depending on the decarbonization action. Also, the "value of 1 point" shown in FIG. 4 is an example and is not limited to the example shown in FIG. 4.

[0058] As shown in FIG. 4, in the embodiment, the acquisition unit 11 acquires the type of points corresponding to decarbonization behavior from a total of eight types of points: "Gold Points," "Silver Points," "Green Points," "Blue Points," "Purple Points," "Red Points," "Yellow Points," and "Corporate-Specific Points" (not shown). Note that the types of points shown in FIG. 4 are examples, and the names of each point are tentative. There may be multiple types of points, and there may be seven or fewer types, or nine or more types.

[0059] Providers can then exchange the points consumed by users for environmental value, which can be used for offsetting, promoting environmental contributions, building customer engagement, and trading. (The environmental value obtained in exchange for points can take various forms depending on the point type, such as J-Credits, other carbon credits, and non-creditable data.) A user selects a decarbonization action menu item from a decarbonization action menu list containing multiple decarbonization action options via a decarbonization application (app) for realizing a decarbonization system. Specifically, the app is installed on a terminal device owned by the user, and the decarbonization action menu list is displayed on the terminal device. The user operates the terminal device to select a decarbonization action menu item containing the desired decarbonization action from the displayed menu. The decarbonization action menu contains information related to the type of decarbonization action, the unit time for performing the decarbonization action, information identifying the provider who set the decarbonization action menu, the type of points (type of decarbonization points) earned by the decarbonization action, and the number of decarbonization points awarded for CO2 emission reduction monitoring information. For example, a user can check information about the decarbonization points awarded for each decarbonization action menu from the decarbonization action menu list displayed on the app, and select the decarbonization action menu that they want to implement.

[0060] The unit time for performing decarbonization actions is a time period divided to count (aggregate) the amount of CO2 emissions reduction, the number of decarbonization actions, the duration of the decarbonization actions, the distance decarbonized, etc. The unit time is set in advance and may be, for example, one day, one week, one month, one year, etc., but is not limited to these. For example, decarbonization points may be awarded for each unit time according to the CO2 emission reduction monitoring information for that unit time.

[0061] "Gold Points" are derived from J-Credits earned through solar energy methodology and are awarded to users when they take environmental actions related to renewable energy (here, decarbonization actions). Providers can exchange "Gold Points" for rewards, for example, to obtain J-Credits derived from renewable energy.

[0062] In other words, the acquisition unit 11 acquires the type of points based on whether the reduction information indicates that the user has selected a decarbonization action related to renewable energy by referring to a table that links each decarbonization action menu stored in the memory unit 15 described below with the type of points.

[0063] Here, when a user selects a decarbonization action menu related to renewable energy, the acquisition unit 11 refers to a table linking each decarbonization action menu with a point type, and acquires "gold points," which are a point type. Furthermore, for example, when the acquisition unit 11 acquires reduction information indicating the results of monitoring an image of a meter reading slip indicating the amount of water, gas, or electricity used, the acquisition unit 11 acquires "gold points" to be awarded according to the monitoring results. Furthermore, for example, when the acquisition unit 11 acquires reduction information indicating the results of monitoring an image of a screen displayed on a monitoring device that monitors the status of power generation by solar power generation, the acquisition unit 11 acquires "gold points" to be awarded according to the monitoring results.

[0064] "Silver Points" are derived from J-Credits earned through various energy-saving methodologies, and are awarded to users when they take decarbonizing actions related to energy conservation. Providers can exchange "Silver Points" for rewards, for example, to obtain J-Credits derived from energy conservation.

[0065] In other words, the acquisition unit 11 acquires the type of points based on whether the reduction information indicates that the user has selected a decarbonization action related to renewable energy by referring to a table that links each decarbonization action menu stored in the memory unit 15 described below with the type of points.

[0066] Here, when a user selects a decarbonization action menu item, such as the introduction of energy-saving equipment, the acquisition unit 11 refers to a table linking each decarbonization action menu item with a point type, and acquires "silver points," which is the point type. Note that the method of monitoring whether the decarbonization action selected by the user is an environmental action related to energy conservation differs depending on the various energy-saving methodologies.

[0067] "Green Points" are awarded to users when they self-report that they have taken decarbonization actions. By exchanging "Green Points" for rewards, providers can obtain data based on the decarbonization actions taken by users, for example.

[0068] That is, the acquisition unit 11 acquires the type of points based on whether or not the reduction information indicates that the user has self-reported that they have implemented decarbonization actions. For example, when the acquisition unit 11 acquires reduction information indicating that the user has self-reported that they have implemented decarbonization actions, it acquires the type of points, "green points." Furthermore, when the acquisition unit 11 acquires reduction information indicating that the user has self-reported based on the analysis results of data from a smart meter, a HEMS, an IoT home appliance, or the like, it acquires the type of points, "green points."

[0069] "Blue Points" are points awarded to users based on the measurement results of the decarbonization actions they have taken. By exchanging "Blue Points" for rewards, providers can obtain data based on the decarbonization actions they have taken, for example.

[0070] That is, the acquisition unit 11 acquires the type of points based on whether the reduction information indicates the measurement result of the decarbonization behavior performed by the user. For example, the acquisition unit 11 acquires the measurement result of the user's delivery receipt history as reduction information, and if the measurement result indicates that the user performed the decarbonization behavior of accepting the delivery at the first delivery, acquires the type of points as "blue points." Furthermore, the acquisition unit 11 acquires the measurement result of the user's travel history by public transportation, bicycle, or walking as reduction information, and if the measurement result indicates that the user performed the decarbonization behavior of traveling by public transportation, bicycle, or walking, acquires the type of points as "blue points."

[0071] "Purple Points" are derived from various voluntary credits and are awarded to users when they take decarbonization actions corresponding to the voluntary credits. The origin of "Purple Points" varies depending on the type of voluntary credit. Providers can obtain voluntary credits by exchanging "Purple Points" for reward menus.

[0072] That is, the acquiring unit 11 acquires the type of points based on whether or not the reduction information indicates that the user has selected a decarbonization action corresponding to the voluntary credit. For example, if the voluntary credit is derived from a reforestation project, the acquiring unit 11 acquires the type of points as "purple points" if it acquires reduction information indicating that the user has selected a decarbonization action related to the reforestation project.

[0073] "Red points" are points awarded to users when they purchase products or services with a low CFP (Carbon Footprint of Products) that are lower than normal purchasing behavior, and are derived from decarbonization actions by users selecting (purchasing) products or services with a lower CFP. Providers can exchange "Red points" for reward menus, for example, to achieve the effect of promoting sales of low CFP products or services.

[0074] That is, the acquisition unit 11 acquires the type of points based on whether the reduction information indicates that the user has selected a decarbonization behavior of purchasing a product or service with low greenhouse gas (here, CO2) emissions. Here, when the determination unit 12 acquires reduction information indicating that the user has selected a decarbonization behavior of purchasing a product or service with low CFP, it acquires the type of points as "red points."

[0075] "Yellow points" are derived from demand response and are awarded to users when they take energy-saving actions in response to demand response. Providers can exchange "Yellow points" for rewards, thereby reducing peak power consumption.

[0076] That is, the acquisition unit 11 acquires the type of points depending on whether the reduction information indicates that the user has selected the decarbonization action of performing power-saving actions in response to demand response. For example, when the reduction information indicates that the user has selected the decarbonization action of performing power-saving actions in response to demand response, the determination unit 12 acquires the type of points, "yellow points."

[0077] "Corporate points" are derived from the unique decarbonization actions desired by the provider, and are awarded to users when they take the unique decarbonization actions desired by the provider. By exchanging "Corporate points" for a rebate menu, it is possible to achieve the effect of taking the decarbonization actions desired by the provider.

[0078] The "corporate points" may have different types of points for each provider. The "corporate points" may be composed of a single provider or multiple providers.

[0079] That is, the acquisition unit 11 acquires the type of points based on whether or not the reduction information indicates that the user has selected the unique decarbonization action desired by the provider. Here, when the reduction information indicates that the user has selected the unique decarbonization action desired by the provider, the acquisition unit 11 acquires the type of points, "corporate-specific points."

[0080] There are various ways to classify points into types, and they are not limited to the classification shown in FIG. 4, as long as they are managed into two or more types of points. Furthermore, the two or more types of points may be classified based on at least one of the following axes: origin, what the provider gains, monitoring method, and monetization. Furthermore, at least one of the multiple point types shown in FIG. 4 is linked to a decarbonization action menu, for example.

[0081] The granting unit 13 grants to the user the number of points calculated by the calculation unit 12 according to the type of points acquired by the acquisition unit 11. In the embodiment, the granting unit 13 updates the point account of the user or group according to the type of points acquired by the acquisition unit 11 so that the new point balance calculated by the calculation unit 12 is included. For example, if the type of points acquired by the acquisition unit 11 is "gold points," the granting unit 13 updates the point account corresponding to "gold points" so that the new point balance calculated by the calculation unit 12 is included.

[0082] The presentation unit 14 presents the user with a rebate menu included in a decarbonization catalog corresponding to the type of points. In the embodiment, the presentation unit 14 presents the rebate menu to the user by displaying the rebate menu that the user can receive in exchange for points on the display 200 of the terminal device 20, as shown in FIG.

[0083] FIG. 5 is a diagram illustrating an example of a decarbonization catalog. For example, when a user wants to use points, the user operates the terminal device 20 to access the decarbonization system 1. Then, the user selects the desired rebate menu from the decarbonization catalog displayed on the display 200 of the terminal device 20 as shown in FIG. 5. Here, the decarbonization catalog is a list of multiple items A2 indicating the contents of each rebate menu, the points required to exchange for the rebate menu, and the type of points. The decarbonization catalog shown in FIG. 5 includes an item A21 indicating a rebate menu that can be exchanged for "Gold Points," an item A22 indicating a rebate menu that can be exchanged for "Silver Points," and an item A23 indicating a rebate menu that can be exchanged for "Green Points." Note that in the example shown in FIG. 5, the decarbonization catalog includes a list of rebate menu items for different point types, but is not limited to this. For example, the decarbonization catalog may include a list of multiple rebate menu items for the same point type.

[0084] For example, when a user selects an item A2 indicating a desired cashback menu from the cashback menu displayed on the display 200 of the terminal device 20, the terminal device 20 transmits identification information indicating the selected cashback menu to the point-giving system 10. The processing unit of the point-giving system 10 subtracts the number of points required to exchange for the cashback menu indicated by the identification information from the user's current points stored in the storage unit 15. The processing unit also transmits the identification information to the management server 3 of the provider that provides the cashback menu. As a result, the provider provides the user with the cashback menu selected by the user.

[0085] The storage unit 15 is a storage device that stores information necessary for the processing performed by the processing unit. The information stored in the storage unit 15 includes computer programs executed by the processing unit. The storage unit 15 is realized by, for example, a semiconductor memory, but is not limited to this and may be realized by, for example, a known information storage medium such as an HDD (Hard Disk Drive).

[0086] The storage unit 15 stores, for example, user IDs (identifiers) that can identify each of multiple users, and points and point types owned by each of the multiple users, in association with each other. The storage unit 15 may also store, in association with the user ID, an action history regarding decarbonization actions taken by each user in the past, a point acquisition history regarding point acquisition, and the like. The point acquisition history is a history indicating points awarded for decarbonization actions taken by each user in the past, the timing (e.g., time) at which the points were awarded, and the like. The storage unit 15 also stores, for example, a decarbonization action menu list, decarbonization action menus, information on providers, and the like, as shown in FIG. 4. The storage unit 15 also stores a table linking each decarbonization action menu with a point type.

[0087] <Operation> The operation of the point-giving system 10 according to the embodiment will be described below with reference to Fig. 6. Fig. 6 is a flowchart showing an example of the operation of the point-giving system 10 according to the embodiment.

[0088] As shown in FIG. 6, the points-giving system 10 accepts from a user an application for membership (enrollment procedure) to use the decarbonization system 1 (S100). The points-giving system 10 may accept the enrollment by, for example, acquiring, via an acquisition unit 11, predetermined information entered by the user via a terminal device 20 on which an app is installed. The predetermined information may include attribute information of the user. By completing the enrollment procedure, the user becomes able to use the decarbonization system 1. Note that the enrollment method is not particularly limited and may be performed by any method.

[0089] Next, the point-assigning system 10 acquires reduction information by accepting a selection of a decarbonization action menu from the user (S110). The user selects a decarbonization action menu including the decarbonization action that the user will perform, for example, from a decarbonization action menu list displayed on the display 200 of the terminal device 20. The point-assigning system 10 may accept the selection of a decarbonization action menu by acquiring, from the terminal device 20, information indicating the decarbonization action menu selected by the user as reduction information via the acquisition unit 11.

[0090] In addition, when the acquisition unit 11 acquires reduction information by referring to a table that links each decarbonization action menu stored in the memory unit 15 with the type of points, the point-assignment system 10 also acquires the type of points (S120).

[0091] The user then puts into practice the decarbonization action selected in step S110. The user may also put into practice multiple decarbonization actions in parallel. The user may also put into practice a decarbonization action included in a one-off decarbonization action menu that has not been selected before the action, or a decarbonization action included in a decarbonization action menu with a set period. The decarbonization action menu list may include such one-off decarbonization action menus, decarbonization action menus with set periods, etc.

[0092] Next, the point-assigning system 10 determines whether a unit time corresponding to the decarbonization action menu has elapsed (S130). The point-assigning system 10 may determine whether a unit time has elapsed based on, for example, the time elapsed from the time when the selection of the decarbonization action menu was accepted in step S110 to the current time, or the time elapsed from the time when the previous unit time elapsed to the current time.

[0093] Next, when it is determined that the unit time has elapsed (Yes in S130), the point-assigning system 10 monitors the decarbonization action selected by the user and calculates the number of points to be assigned based on the acquired reduction information (S140). The point-assigning system 10 acquires the user's track record of decarbonization actions accumulated over the unit time and tallys it based on a predetermined monitoring method. As a result, a total value of the user's track record of decarbonization actions over the unit time is acquired. The point-assigning system 10 then calculates points to be assigned to the user based on the total value of the track record of decarbonization actions. For example, the point-assigning system 10 calculates the number of points to be assigned to the user based on the total value of the track record of decarbonization actions and a decarbonization action menu that includes the decarbonization action. The buying and selling price of carbon credits (e.g., J-credits) may be used to calculate the number of points to be assigned.

[0094] Furthermore, if the point-giving system 10 determines that the unit time has not elapsed (No in S130), it returns to step S130 and waits until the unit time has elapsed.

[0095] Next, the point-giving system 10 grants to the user the number of points calculated by the calculation unit 12 according to the type of points acquired by the acquisition unit 11 (S150). Specifically, the point-giving system 10 updates the point account of the user or group according to the type of points acquired by the acquisition unit 11 so that the new point balance calculated by the calculation unit 12 in S140 is obtained. Note that the timing or cycle of granting points is not particularly limited.

[0096] Next, the point-giving system 10 accepts a selection of a rebate menu to be exchanged for points from the user (S160). The user selects a rebate menu to be exchanged from, for example, a decarbonization catalog displayed on the display 200 of the terminal device 20. The point-giving system 10 may accept the selection of the rebate menu by acquiring, via the terminal device 20, information indicating the rebate menu selected by the user through the acquisition unit 11.

[0097] A decarbonization catalog may exist for each type of point. Points can be exchanged for items in stock, but there may be restrictions, such as points awarded in accordance with an action menu established by an environmental contribution corporation can only be exchanged for items in the rebate menu provided by that environmental contribution corporation.

[0098] Next, the point-giving system 10 confirms the selection of the rebate menu accepted in step S160 and executes the rebate (S170). The point-giving system 10 notifies the provider of the rebate menu that the selection of the rebate menu accepted in step S160 has been confirmed. The point-giving system 10 also updates the points held by the user by subtracting the points required for exchange for the rebate menu accepted in step S160 from the points held by the user.

[0099] The processing from steps S130 to S150 may be executed repeatedly. Furthermore, the exchange of points for multiple rebate menus may be executed all at once. The point-giving system 10 may, for example, automatically continue the processing from steps S130 to S150. This allows the point-giving system 10 to award points to the user for each unit of time according to the performance of decarbonization actions during that unit of time. An upper limit time for the cumulative time of the unit of time may be set. The point-giving system 10 may automatically continue the processing from steps S130 to S150 until the upper limit time is reached.

[0100] <Advantages> The advantages of the point-assigning system 10 according to the embodiment will be described below. As described above, the point-assigning system 10 according to the embodiment determines the type of points according to the type of decarbonization behavior performed by the user and assigns points to the user according to the determined point type. Therefore, the point-assigning system 10 according to the embodiment allows points to be exchanged for multiple types of environmental value, making it easier for providers to obtain environmental value according to their desired environmental behavior. This has the advantage of making it easier for providers to offer users an environmental value rebate menu, which in turn makes it easier for providers to encourage users to engage in the decarbonization behavior they desire. Another advantage is that it makes it easier for users to recognize the types of environmental value created by environmental behavior.

[0101] In particular, the point-granting system 10 according to the embodiment has the advantage of being able to determine the type of points to be awarded according to a wide variety of environmental behaviors (including environmentally conscious living), ranging from environmental behaviors that are relatively less relevant to greenhouse gas reduction to environmental behaviors that are relatively more relevant to greenhouse gas reduction.

[0112] In addition, the point-granting system 10 according to the second aspect further includes a presentation unit 14 that presents to the user or group, for each type of point, a redemption menu that can be exchanged for the points granted to the user or group in the first aspect.

[0113] According to the point-giving system 10, a user or group can grasp the redemption menu that can be exchanged using points, which makes the user or group more conscious of using points. Therefore, the point-giving system 10 has the advantage of easily encouraging the user or group to utilize points.

[0114] In addition, in the point-granting system 10 according to the third aspect, in the first or second aspect, the acquisition unit 11 acquires the type of points based on whether the reduction information indicates that the user or group has selected environmental behavior related to renewable energy or energy conservation.
