Description

[Technical Field]

[0001] The present disclosure relates to a presentation system, a presentation method, and a program. [Background technology]

[0002] In recent years, the increase in CO2 emissions has become a problem, and there is a demand for a reduction in CO2 emissions. In particular, there is a demand for reduction in CO2 emissions not only from companies that emit a large amount of CO2, but also from individuals. However, it is known that it is difficult to actually feel the reduction in CO2 emissions at the individual level. In order to make CO2 emissions more tangible even at the individual level, it has been proposed to visualize the amount of CO2 reduction, as shown in Patent Document 1, for example.

[0004] However, even if the amount of CO2 reduction is visualized, there is still the problem that it is difficult for users to realize or understand the effect of their decarbonization actions on environmental issues.

[0008] Furthermore, a program according to one aspect of the present disclosure is a program for causing a computer to execute the presentation method described above. [Effects of the Invention]

[0011] Hereinafter, the embodiments will be described in detail with reference to the drawings. Note that the embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component placement and connection forms, steps, and step order shown in the following embodiments are merely examples and are not intended to limit the present disclosure. Furthermore, among the components in the following embodiments, components not recited in independent claims will be described as optional components.

[0012] It should be noted that the drawings are schematic diagrams and are not necessarily strict illustrations. In addition, in the drawings, substantially the same components are denoted by the same reference numerals, and overlapping descriptions may be omitted or simplified.

[0013] (Embodiment) [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.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] 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.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] In the following, decarbonization points refer to environmental points that include points other than decarbonization actions, and include points obtained by reducing CO2 emissions, points obtained by reducing greenhouse gas emissions other than CO2, and points obtained by actions other than reducing greenhouse gas emissions.

[0022] Furthermore, decarbonization points are an example of environmental points awarded for the above-mentioned environmental actions.

[0023] 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.

[0024] 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.

[0025] 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, as will be described later using Figure 10, there are multiple point types corresponding to the decarbonization action menu, i.e., the type of decarbonization action.

[0026] The multiple point types according to the type of decarbonization action include, for example, points derived from J-Credits based on solar power methodologies and awarded to users when they take environmental action related to renewable energy (here, decarbonization actions); points derived from J-Credits based on various energy-saving methodologies and awarded to users when they take decarbonization actions related to energy saving; points derived from users' self-reporting that they have taken decarbonization actions and awarded to users when they self-report that they have taken decarbonization actions; points derived from the measurement results of the decarbonization actions taken by users and awarded to users according to the measurement results of the decarbonization actions taken by users; points derived from various voluntary credits and awarded to users when they take decarbonization actions corresponding to the voluntary credits; points derived from decarbonization actions in which users select (purchase) goods or services with a lower CFP (Carbon Footprint of Products) than normal purchasing actions and awarded to users when they purchase products or services with a lower CFP; and points derived from unique decarbonization actions desired by providers and awarded to users when they take unique decarbonization actions desired by the provider.

[0027] The types of points are not limited to these.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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).

[0035] 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)).

[0036] 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 a different method for 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 each provider. Rebate options can be viewed at any time. Users select the desired reward option from a decarbonization catalog containing multiple reward options offered by each provider 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] Conventionally, decarbonization points accumulated by users through decarbonization actions have been exchanged for electronic money such as PayPay (registered trademark) or Amazon gift cards, or cash. However, since the value of electronic money or cash does not fluctuate depending on differences in values ​​such as user preferences, it has not been possible to exchange decarbonization points for value objects (rebate menus) whose value fluctuates depending on differences in values ​​such as user preferences. In other words, it has not been possible to exchange environmental value for exchange objects that provide greater value to users.

[0042] Therefore, the inventors of the present application have conducted extensive research into exchange systems and the like that can support the exchange of environmental value (e.g., decarbonization points within a decarbonization system) generated by environmental actions (here, decarbonization actions) for exchange items that are more valuable to users, and have devised the exchange system and the like described below. Specifically, the inventors of the present application have devised an exchange system and the like that allows users to select exchange items from a decarbonization catalog containing a variety of products and services, the value of which varies depending on the user, thereby enabling users to select products and services that they perceive as valuable. The ability to exchange for such products and services is expected to have the effect of encouraging users to exchange. In other words, the ability to exchange for such products and services is expected to have the effect of encouraging users to perform decarbonization actions. The decarbonization system can also be said to be a mechanism for providing users with products and services that correspond to decarbonization actions.

[0043] To help users continue to practice decarbonization, the amount of CO2 emissions reduced by the user's decarbonization actions is displayed on a terminal device as a measure of effectiveness. Typically, the extent to which CO2 emissions have been reduced relative to the user's baseline (i.e., the difference from the baseline) is displayed, typically as a CO2 amount. Alternatively, the amount may be converted into the equivalent number of trees (e.g., the number of trees) required to absorb that amount of CO2. However, such a display is often unfamiliar to users and is therefore inappropriate for users to realize or understand the effects of their decarbonization actions. In other words, to enable users to realize or understand the benefits of their decarbonization actions in addressing environmental issues, it is necessary to display the amount of CO2 emissions reduced by the user using a scale familiar to the user. In other words, by displaying the amount of CO2 emissions reduced by the user using a scale familiar to the user, the effects of the decarbonization actions can be realized or understood.

[0044] [composition] FIG. 2 is a block diagram showing a functional configuration of a presentation system according to an embodiment. FIG. 3 is a block diagram showing information stored in a storage unit of the presentation system according to an embodiment. As shown in FIG. 2, the presentation system 100 includes an acquisition unit 101, a user information acquisition unit 102, a storage unit 103, a generation unit 104, and a presentation unit 105. The presentation system 100 is realized as an information processing function of an information processing server using a computer such as a cloud server or an edge server. More specifically, the information processing function of the presentation system 100 is realized by executing a predetermined program stored in the memory using a processor and memory provided in the computer. The acquisition unit 101, the user information acquisition unit 102, the generation unit 104, and the presentation unit 105 included in the presentation system 100 are each part of the information processing function. Therefore, the acquisition unit 101, the user information acquisition unit 102, the notification unit 103, and the presentation unit 104 are each part of a program for realizing the information processing function. The storage unit 103 is a partial area of ​​the memory used in information processing.

[0045] The presentation system 100 is a system accessible to multiple users, including one user, primarily described below, and other users.

[0046] In the following description, unless otherwise specified, the user is assumed to be a user who performs decarbonization actions.

[0047] The acquisition unit 101 is a functional part that acquires CO2 emission reduction information from a user. The acquisition unit 101 acquires CO2 emission reduction information of not only the user but also all users who use the presentation system 100. Then, by individually executing the following process for each of the multiple users, all users can receive the presentation information individually.

[0048] The acquisition unit 101 communicates with at least one of a terminal device for an energy management system (HEMS) installed in each of the multiple users' homes and a portable terminal device (e.g., a smartphone, a tablet device, a PC, etc.) owned by each of the multiple users, thereby acquiring CO2 emission reduction information for each of the multiple users via these terminal devices. When the acquisition unit 101 receives input of the results of decarbonization actions via the terminal device, the acquisition unit 101 communicates with the terminal device in response to the input to acquire CO2 emission reduction information. In other words, the acquisition unit 101 acquires CO2 emission reduction information for each user by receiving input of the results of decarbonization actions. Note that the terminal device 20 may be a device having a monitor, or a device with a VPA function such as a smart speaker connected to the monitor so as to be able to communicate with the monitor, or a device integrated with the monitor so as to be able to communicate.

[0049] The CO2 emission reduction information is information about the results of decarbonization actions taken by each user. Specifically, the CO2 emission reduction information includes information about what actions were taken to reduce CO2 emissions, information about the extent to which those actions were taken, and, in some cases, information about the extent to which CO2 emissions were reduced by those actions. In this case, the terminal device used for input is capable of calculating the amount of CO2 emission reduction. On the other hand, even if the terminal device does not have such a function for calculating the amount of CO2 emission reduction, the CO2 emission reduction information can be calculated by the presentation system 100 from information about what actions were taken to reduce CO2 emissions and information about the extent to which those actions were taken.

[0050] In the presentation system 100, decarbonization actions are classified by one or more pre-set tags, and CO2 emission reduction information can be defined by the tags attached to each action. For example, the type of action can be represented by the type of tag attached. Furthermore, specific performance values ​​can be set for some of the tags, and the extent to which the action was performed can be represented by these performance values. The tags for which performance values ​​can be set include a tag for the amount of CO2 emission reduction, and this tag can represent the extent to which CO2 emissions have been reduced.

[0051] As an example, the tags include tags that indicate how decarbonization actions, such as the introduction of energy-saving equipment, the reduction of CO2 emissions through the use of renewable energy, the reduction of the frequency of use of electrical equipment, and forest management that promotes CO2 absorption, lead to CO2 emission reductions. The tags also include tags that indicate the specific nature of the energy-saving equipment or electrical equipment. The tags also include tags that indicate the specific source of renewable energy. The tags also include tags that indicate the specific extent of renewable energy usage. The tags also include tags that indicate the specific frequency of use of electrical equipment. The tags also include tags that indicate the specific type of forest management. The tags also include tags that indicate the specific frequency of forest management. Other tags may also be included that are not listed above.

[0052] The user information acquisition unit 102 is a functional part that acquires, for each user, user information including at least one of the equipment owned by the user and the operating status of the equipment. Here, the equipment owned by the user is equipment that emits CO2. In other words, the equipment consumes energy during its operation. Examples of equipment include electrical appliances such as smartphones, PCs, air conditioners, refrigerators, lighting devices, electric water heaters, and electric vehicles, as well as fuel-powered appliances such as gasoline-powered vehicles, gasoline-powered generators, gas fan heaters, and gas stoves. Each of these pieces of equipment can be converted into the amount of CO2 emissions (emitted to generate that energy) equivalent to the amount of energy consumed during operation.

[0053] It is common for users to use these facilities differently and with different frequencies. For example, some users run their air conditioners 24 hours a day, while others run them only for a few hours each day while they are at home. Furthermore, even among gasoline-powered vehicles, fuel economy varies, resulting in different fuel consumption amounts, or converted CO2 emissions, for the same distance traveled. Electric vehicles also vary in fuel economy, resulting in different converted CO2 emissions for the same distance traveled, depending on the amount of electricity used or the emission coefficient of the power source used to charge the vehicle. Therefore, by converting energy consumption based on the usage history of the user's actual facilities into CO2 emissions and presenting them, it is possible to present CO2 emissions on a scale more familiar to users. For these purposes, acquiring user information is effective.

[0054] On the other hand, even without acquiring such user information, equipment can calculate general energy consumption from the past usage history of many general users (decarbonization actions taken by many general users). Such general energy consumption can be used to convert and present the CO2 emissions reduced by the user's decarbonization actions. Even if it is general energy consumption, it is the energy consumption of equipment that is familiar to users (electrical appliances and fuel-powered equipment that are normally used at home). CO2 emissions converted using such energy consumption are also shown on a scale that is familiar to users, making it easy for users to feel the effects and making it meaningful to measure.

[0055] The user information acquisition unit 102 also has a function of accepting a scale selection by the user. The scale selection involves the storage unit 103, which will be explained below.

[0056] The storage unit 103 is realized by a semiconductor memory or the like, and stores scale information relating to a plurality of scales, such as first scale information 103a and second scale information 103b, as shown in FIG. 3 . For example, the first scale information 103a is information for converting CO2 emissions using the first scale. More specifically, the first scale is, for example, the operating time of an air conditioner and includes a function for calculating the operating time of the air conditioner per unit of CO2 emissions. When converting CO2 emissions using the first scale, the operating time of the air conditioner corresponding to the substituted CO2 emissions can be calculated by substituting the CO2 emissions into the function. Furthermore, for example, the second scale information 103b is information for converting CO2 emissions using the second scale. More specifically, the second scale is, for example, the mileage of a gasoline-powered automobile and includes a function for calculating the mileage of the gasoline-powered automobile per unit of CO2 emissions. When converting CO2 emissions using the second scale, the mileage of the gasoline-powered automobile corresponding to the substituted CO2 emissions can be calculated by substituting the CO2 emissions into the function. The measure of distance traveled may simply be a measure of distance shown in kilometers (km) or miles (mi), or it may be a measure that expresses the distance as a coefficient multiplied by the distance (straight-line distance or road distance) between specified cities, such as between Tokyo and Fukuoka or between Osaka and New York.

[0057] The scale information such as the first scale information 103a and the second scale information 103b may be updated to a scale of the equipment actually owned by the user, i.e., a unique scale based on at least one of the equipment owned by the user and the operating status of the equipment, based on the user information. In this case, the above function is optimized to become a user-specific function based on the user information.

[0058] For example, the user can view a list of scale information stored in the storage unit 103 on a terminal device. The user then selects one or more scale information items from the list that are familiar to the user (easy to understand). This determines the scale information used for conversion. That is, the user's selection determines whether CO2 emissions are converted using the first scale of the first scale information 103a, the first scale of the second scale information 103b, or the scale of other scale information. The user can select two or more scale information items, or can select no scale information at all. If no scale information is selected, default scale information (e.g., the first scale information 103a) is set, and the scale of that scale information is used to convert CO2 emissions. Even in this case, if the user does not make a selection (at the user's discretion), the set scale information is used, making it possible to present CO2 emissions using a scale familiar to the user. The default scale information may be set to the scale information most selected by multiple users using the presentation system 100.

[0059] Returning to Figure 2, the generation unit 104 calculates the amount of CO2 emissions reduced from the acquired CO2 emission reduction information, converts the reduced CO2 emissions using a scale set by the user, and generates presentation information including the conversion information. The presentation information preferably includes, in addition to the conversion information, emission information that indicates the reduced CO2 emissions themselves before conversion. By repeatedly presenting the information multiple times, the user can grasp the scale indicated by the CO2 emissions themselves, making it easier for the user to realize the effect of reducing CO2 emissions.

[0060] The presentation unit 105 is a functional part that presents the generated presentation information on a terminal device owned by the first user. The presentation information is, for example, an information presentation page for an application. By presenting the presentation information, the CO2 emissions reduced by the decarbonization actions taken by the user based on the user's CO2 emission reduction information can be viewed using the scale of the scale information selected by the user.

[0061] In this way, the first user can understand the decarbonization actions taken by the user by viewing the presented information based on the user's CO2 emission reduction information. At that time, by viewing the conversion information included in the presented information for measuring the effect, the converted CO2 emissions are displayed using the scale of the scale information selected by the user, so the user can confirm the CO2 emissions using a scale that is familiar to the user. In this way, the presentation system 100 can present information that the user can easily relate to.

[0062] [Operation] Next, the operation of the presentation system 100 will be described with reference to FIGS. 4 to 6. FIG. 4 is a flowchart showing an example of the operation of the point-giving system. FIG. 5 is a flowchart showing an example of the operation of the presentation system according to the embodiment. FIG. 6 is a diagram showing an example of a screen display of the presentation system according to the embodiment. In the operation example described below, the operation of the point-giving system executed in parallel with the presentation system 100 will be described with reference to FIG. 4, and then the operation of the presentation system 100 will be described with reference to FIG. 5. The point-giving system is a system for awarding points to users for decarbonization actions they have taken. Users can obtain various rewards (rebate menus) by spending the awarded points. Meanwhile, here, the presentation system 100 will be described as one of the services provided to users who have registered to use the decarbonization system.

[0063] As shown in FIG. 4, the point-giving system accepts from a user an application for membership (enrollment procedure) to use the decarbonization system (S100). The point-giving system may accept the enrollment by, for example, acquiring, via an acquisition unit (which may be the same as or different from acquisition unit 101), predetermined information entered by the user via a terminal device on which an app is installed. The predetermined information may include attribute information of the user. Completing the enrollment procedure enables the user to use the decarbonization system. Note that the enrollment method is not particularly limited and may be performed by any method.

[0064] Next, the point-assigning system acquires reduction information by accepting a selection of a decarbonization action menu from the user (S110). The user selects a decarbonization action menu that includes the decarbonization action that the user will perform, for example, from a decarbonization action menu list displayed on the display of the terminal device. The point-assigning system may accept the selection of the decarbonization action menu by acquiring, from the terminal device via the acquisition unit, information indicating the decarbonization action menu selected by the user as reduction information.

[0065] In addition, when the acquisition unit acquires reduction information by referring to a table that links each decarbonization action menu stored in a memory unit (which may be the same as or different from memory unit 103) with the type of points, the point awarding system also acquires the type of points (S120).

[0066] 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.

[0067] Next, the point-assigning system determines whether a unit time corresponding to the decarbonization action menu has elapsed (S130). The point-assigning system 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.

[0068] Next, when the point-assigning system determines that the unit time has elapsed (Yes in S130), it monitors the decarbonization action selected by the user and calculates the number of points to be awarded based on the acquired reduction information (S140). The point-assigning system acquires the user's track record of decarbonization actions accumulated over the unit time and tallys it based on a predetermined monitoring method. This acquires the total value of the user's track record of decarbonization actions over the unit time. The point-assigning system then calculates the points to be awarded to the user based on the total value of the track record of decarbonization actions. For example, the point-assigning system calculates the number of points to be awarded 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 awarded.

[0069] Moreover, if the point-giving system determines that the unit time has not elapsed (No in S130), it returns to step S130 and waits until the unit time has elapsed.

[0070] Next, the point-giving system grants the user the number of points calculated by the calculation unit according to the type of points acquired by the acquisition unit (S150). Specifically, the point-giving system updates the point account of the user or group according to the type of points acquired by the acquisition unit so that the new point balance is the one calculated by the calculation unit in S140. Note that the timing or cycle of point granting is not particularly limited.

[0071] Next, the point-giving system 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 of the terminal device. The point-giving system may accept the selection of the rebate menu by acquiring information indicating the rebate menu selected by the user via the terminal device through an acquisition unit.

[0072] 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.

[0073] Next, the point-giving system confirms the selection of the rebate menu accepted in step S160 and executes the rebate (S170). The point-giving system 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 also updates the points held by the user by subtracting the points required to exchange for the rebate menu accepted in step S160 from the points held by the user.

[0074] The processing from steps S130 to S150 may be repeated. Furthermore, points may be exchanged for multiple rebate menus all at once. The point-giving system may, for example, automatically continue the processing from steps S130 to S150. This allows the point-giving system 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 may be set for the cumulative time of the unit of time. The point-giving system may automatically continue the processing from steps S130 to S150 until the upper limit is reached.

[0075] The presentation system 100 executes the operation of the presentation system 100 shown in FIG. 5 in parallel with steps S101 to S170 after the service point awarding system provided to a user who has joined the point awarding system accepts the user's membership to use the decarbonization system (after S100).

[0076] The information processing server of the presentation system 100 is always in an operating state except in an emergency such as during maintenance, and acquires user information and accepts registration of CO2 emitting facilities (step S101). CO2 emitting facilities may be registered by users, or by administrators or providers. Note that multiple CO2 emitting facilities may be registered. In other words, in step S101, the presentation system 100 accepts user settings for converting CO2 emissions.

[0077] Depending on the CO2 emitting facility registered in step S101, the monitoring period, monitoring method, and CO2 emission amount (conversion coefficient) for unit activity amount are determined (step S102). Alternatively, depending on the CO2 emitting facility registered in step S101, the CO2 emission amount (conversion coefficient) for unit activity amount may be determined based on statistical values ​​or estimated values ​​(step S102). In other words, in step S102, the presentation system 100 determines a scale for converting CO2 emission amount.

[0078] The user's CO2 emission behavior is monitored, and the amount of CO2 emission behavior per unit of CO2 emission is calculated based on the monitoring results (step S103). Alternatively, the amount of CO2 emission behavior per unit of CO2 emission may be calculated based on statistical values ​​or estimated values ​​of the user's CO2 emission behavior. In other words, in step S103, the presentation system 100 converts the amount of CO2 emission.

[0079] The presentation unit 105, for example, performs the conversion of CO2 emissions in step S103 based on the information on the user's track record of decarbonization actions acquired in step S140, and presents to the user's terminal device the amount of CO2 emission action equivalent to the amount of CO2 emission reduction due to the decarbonization action (step S104). In other words, in step S104, the presentation system 100 generates presentation information using the result of converting the CO2 emissions, and presents the generated presentation information.

[0080] If multiple CO2 emitting facilities are registered, multiple CO2 emission action amounts corresponding to each CO2 emitting facility may be presented. Also, the user, administrator, or provider may select which facility's CO2 emission action amount is to be presented. Also, which facility's CO2 emission action amount is to be presented may be determined randomly.

[0081] It should be noted that steps S101 to S104 do not have to be performed in this order; for example, step S101 may be performed after step S102. Thus, the order of steps shown in Fig. 5 is an example, and the steps may be performed in a different order, or other steps not shown in Fig. 5 may be performed between steps. Also, some of the steps shown in Fig. 5 are not essential, and the non-essential steps may be omitted.

[0082] FIG. 6 shows how presentation information is presented on a terminal device. In FIG. 6, (a) and (b) each show different examples of presentation information. As shown in FIG. 6(a), the user has taken an action to reduce CO2 emissions by self-consuming electricity through solar power generation, thereby reducing the amount of electricity purchased from the power company and curbing the use of electricity with high CO2 emissions, such as thermal power generation. By showing that the amount of CO2 emissions reduced by self-consuming electricity through solar power generation is equivalent to the amount of CO2 emissions reduced by not running an air conditioner 24 hours a day for x years, it is easy to understand that a reduction has been achieved. It shows that this was achieved by the action of self-consuming electricity through solar power generation.

[0083] Also, Figure 6(b) differs from Figure 6(a) in the way the conversion information is presented. That is, Figure 6(b) shows that the CO2 emissions if solar power generation were not self-consumed would be equivalent to the CO2 emissions if an air conditioner were operated 24 hours a day for x number of years, and by showing how much CO2 would be emitted if no contribution to reductions were made, it is easier to understand that, paradoxically, contributions to reductions have been achieved. Comparing (b) of FIG. 6 with (a) of FIG. 6, even though the reduction in CO2 emissions is the same, there is a difference between the presentation of "CO2 emission reductions if the air conditioner is not operated 24 hours a day for x years" and the presentation of "CO2 emissions if the air conditioner is operated 24 hours a day for x years." In other words, there is a difference between converting the amount as CO2 emissions or as CO2 emission reductions. Since these two display examples may give different impressions when presented, it may be possible to make it selectable by settings of the user, administrator, or provider whether to convert as CO2 emissions or as CO2 emission reductions.

[0084] In (a) or (b), the specifications or operation schedule of the CO2 emitting equipment (e.g., air conditioner), the underlying environmental conditions, and the housing specifications can be calculated based on the user's specific conditions, the conditions set by the administrator, or the conditions set by the provider.

[0085] It may also be converted into the equivalent amount of trees (number of trees, etc.) required to absorb CO2.

[0086] [Effects, etc.] As described above, the presentation system 100 in the first aspect includes an acquisition unit 101 that acquires CO2 emission reduction information regarding the performance of a user who performs decarbonization actions; a generation unit 104 that generates presentation information including conversion information that converts the CO2 emissions reduced by the decarbonization actions performed by the user into a scale based on the user's CO2 emission reduction information; and a presentation unit 105 that presents the generated presentation information on a terminal device owned by the user.

[0087] The presentation system 100 can present the CO2 emissions reductions resulting from the decarbonization actions taken as a result of conversion using a scale set by the user, allowing the user to check the CO2 emissions using a more familiar scale. In other words, it can present information that is easy for the user to relate to.

[0088] The presentation system 100 according to the second aspect is the presentation system 100 according to the first aspect, in which the CO2 emission reduction information includes the amount of CO2 emission reduced by the decarbonization action taken by the user.

[0089] This allows the amount of CO2 emissions reduced by the decarbonization action taken to be obtained directly from the acquired CO2 emission reduction information.

[0090] Furthermore, the presentation system 100 in the third aspect is the presentation system 100 described in the first or second aspect, and further includes a memory unit 103 in which first scale information 103a for converting CO2 emissions using a first scale and second scale information 103b for converting CO2 emissions using a second scale different from the first scale are stored, and the scale set by the user is the scale in one of the scale information selected by the user from the first scale information 103a and the second scale information 103b stored in the memory unit 103.

[0091] This allows the amount of CO2 emissions reduced by the decarbonization action taken to be converted using the scale of one of the first scale information and the second scale information selected by the user.

[0092] Furthermore, the presentation system 100 in a fourth aspect is the presentation system 100 described in any one of the first to third aspects, and the presentation information includes emission information indicating the CO2 emissions reduced by the decarbonization actions taken by the user before conversion.

[0093] This makes it possible to present information that includes emission amount information together with conversion information.

[0094] Furthermore, the presentation system 100 in the fifth aspect is the presentation system 100 described in any one of the first to fourth aspects, and further includes a user information acquisition unit 102 that acquires user information regarding at least one of equipment owned by the user that consumes energy and operates, and the operating status of the equipment, and the scale set by the user is a user-specific scale calculated from the equipment and the operating status of the equipment based on the user information.

[0095] This allows the amount of CO2 emissions reduced by the decarbonization actions taken to be converted into a user-specific measure calculated from the equipment and the operating status of the equipment based on user information.

[0096] Furthermore, the presentation system 100 in the sixth aspect is the presentation system 100 described in any one of the first to fifty-sixth aspects, and the scale set by the user is a scale based on the decarbonization actions taken by a large number of general users.

[0097] This allows the amount of CO2 emissions reduced by decarbonization actions taken to be calculated using a scale based on the decarbonization actions taken by a large number of ordinary users.

[0098] Furthermore, the presentation system 100 in a seventh aspect is the presentation system 100 according to any one of the first to fifth aspects, and the scale set by the user is a scale based on the decarbonization actions taken by the user in the past.

[0099] This allows the amount of CO2 emissions reduced by the decarbonization actions taken by the user to be converted into a scale based on the decarbonization actions taken in the past.

[0100] Furthermore, the presentation system 100 in the eighth aspect is the presentation system 100 according to any one of the first to seventh aspects, and the scale set by the user is a scale based on the amount of CO2 emissions equivalent to the energy consumed by the equipment that operates by consuming energy.

[0101] This allows the reduction in CO2 emissions resulting from decarbonization actions to be calculated using a scale based on the CO2 emissions equivalent to the energy consumed by equipment that operates by consuming energy.

[0102] In addition, the presentation method in the ninth aspect is a presentation method executed by a computer, and includes the steps of acquiring CO2 emission reduction information regarding the performance of a user who is performing decarbonization actions; generating presentation information including conversion information that converts the CO2 emissions reduced by the decarbonization actions performed by the user based on the user's CO2 emission reduction information using a scale set by the user; and presenting the generated presentation information on a terminal device owned by the user.

[0103] This can achieve the same effects as the presentation system described above.
