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 reducing carbon emissions such as CO2 (so-called decarbonization actions). In particular, decarbonization actions are being called for not only from companies that emit a large amount of CO2, but also from individuals. However, it is known that decarbonization actions at the individual level are difficult to realize and to continue. In order to continue decarbonization actions at the individual level, for example, as shown in Patent Document 1, it has been proposed to visualize the amount of CO2 reduction and provide cost incentives.

[0004] However, there is a problem in that motivation to engage in decarbonization actions at the individual level is easily diminished. In other words, it is difficult to maintain motivation for decarbonization actions at the individual level. Therefore, the present disclosure provides a presentation system and the like for increasing motivation to engage in decarbonization actions at the individual level. [Means for solving the problem]

[0007] 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]

[0010] 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.

[0011] 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.

[0012] (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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] 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.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] Furthermore, decarbonization points are an example of environmental points awarded for the above-mentioned environmental actions.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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 the unique decarbonization actions desired by the provider.

[0026] The types of points are not limited to these.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] In addition, 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 reduction amounts are not converted into CO2 (not quantified).

[0034] 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)).

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] Another problem is that motivation to take decarbonization action at the individual level is easily diminished. In other words, it is difficult to maintain motivation to take decarbonization action at the individual level.

[0042] Specifically, the total amount of greenhouse gas emissions reductions, such as CO2, that can be achieved at the individual level is extremely limited compared to the global scale. Furthermore, for example, if an individual undertakes decarbonization actions alone without the support of a community, that individual is likely to feel a sense of loneliness, which is thought to be one factor that reduces their motivation to take decarbonization actions. Furthermore, working alone can lead to a sense of unfairness toward those around them who are not taking decarbonization actions, which may lead to a feeling of not wanting to do it alone. Furthermore, even though decarbonization actions are generally referred to as such, there are many different specific approaches, and individuals may find themselves unsure of where to start and how to do it.

[0043] Another issue that is separate from motivation is that there are cases where it is difficult or impossible to put decarbonization into practice by one person alone. Furthermore, while it is possible to take action alone, there are also cases where cooperation with multiple people is more effective.

[0044] 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.

[0045] [composition] The presentation system in this embodiment provides functions (described in detail below) for presenting, notifying, and comparing among multiple users who have formed a community. Forming a community requires, in addition to the above-described functions for presenting, notifying, and comparing, functions for managing user profiles, functions for sharing and posting content, functions for communication between users, functions for networking between users, and functions for interaction and engagement. The presentation system described below is realized using a combination of some of the multiple functions related to the formation of these communities, and a portion of some of the multiple functions.

[0046] The above-mentioned user profile management functions consist of user registration and login functions for managing the process of new users creating accounts and existing users accessing accounts, a profile information editing function for users to update and manage personal information such as self-introductions and profile photos, and a privacy setting function for users to set options to control the extent to which their information is made public and who can view their content.

[0047] The content sharing and posting functions mentioned above include a status update function that allows users to share their current feelings and activities in short sentences, a photo and video posting function that allows users to upload and share images and videos, a link posting function that allows users to share links to access websites that interest them, a blog entry and article posting function that allows users to post long content and articles, and a stories function that allows users to post content that disappears after a certain period of time and share daily events and thoughts in the form of limited-time short movies.

[0048] In addition, the above-mentioned communication functions between users include a message sending and receiving function that allows users to exchange messages privately or publicly with each other, a comment function that allows users to leave feedback on other users' posts, and a video call and voice call function that allows users to make video calls and voice calls with each other in real time.

[0049] The above-mentioned user-to-user networking functions include friend registration and follow functions that allow users to add other users as friends or followers and track each other's activities, group and community participation functions that allow users to join groups and communities based on specific topics or interests, and event creation and management functions that allow users to create events, manage participants, and share event information.

[0050] The above-mentioned interaction and engagement functions consist of simple reaction functions such as "Like!" and "Heart" that allow users to show a favorable response to posts, share, retweet and repost functions that allow users to share content that they like with their own profiles and followers, and voting and survey functions that allow users to gather opinions on posts.

[0051] The following will be specifically described focusing on a combination of several functions among a plurality of functions relating to the formation of a community, and a presentation system realized using a portion of a certain function among a plurality of functions.

[0052] FIG. 2 is a block diagram showing a functional configuration of a presentation system according to an embodiment. As shown in FIG. 2, the presentation system 100 includes an acquisition unit 101, a comparison unit 102, a notification unit 103, and a presentation unit 104. 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 memory using a processor and memory provided in the computer. The acquisition unit 101, the comparison unit 102, the notification unit 103, and the presentation unit 104 included in the presentation system 100 are each part of the information processing function. Therefore, the acquisition unit 101, the comparison unit 102, the notification unit 103, and the presentation unit 104 are each part of a program for realizing the information processing function.

[0053] The presentation system 100 is a system accessible by multiple users, including a first user and a second user. The first user and the second user will be described as forming a community that includes each other, but it is not necessary for all of the multiple users to be included in the community. The presentation system 100 acquires CO2 emission reduction information based on the results of actions taken by a first user in the community, and generates presentation information based on the CO2 emission reduction information and presents it to a second user. The relationship between the first user and the second user in the community may be, for example, a unidirectional relationship in which presentation information based on the CO2 emission reduction information of the first user is presented to the second user, or a bidirectional relationship in which presentation information based on the CO2 emission reduction information of the first user is presented to the second user, and presentation information based on the CO2 emission reduction information of the second user is presented to the first user.

[0054] In the following description, unless otherwise specified, both the first user and the second user are assumed to be users who perform decarbonization actions. However, as long as at least the first user is a user who performs decarbonization actions, the second user is not limited to the above.

[0055] The acquisition unit 101 is a functional part that acquires CO2 emission reduction information from the first user and the second user. The acquisition unit 101 acquires CO2 emission reduction information of all users who use the presentation system 100, such as the first user and the second user. Any one of the multiple users is the first user, and any other one is the second user. However, it is also possible to form a community that includes only one user, in which case the first user and the second user are the same person.

[0056] 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, and acquires CO2 emission reduction information of 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 and acquires CO2 emission reduction information in response to the input. In other words, the acquisition unit 101 acquires CO2 emission reduction information of each user by receiving input of the results of decarbonization actions.

[0057] The terminal device 20 is an information terminal carried by a user. The terminal device 20 may be, for example, an information terminal in which the dedicated decarbonization application described above is installed. The terminal device 20 may be a portable information terminal such as a smartphone or a tablet, a stationary information terminal such as a PC (personal computer), a HEMS, or a device having a monitor, a device having 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 with the monitor.

[0058] 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, how much of each action was taken, and, in some cases, how much CO2 emissions were reduced by each action.

[0059] 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.

[0060] 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.

[0061] The comparison unit 102 is a functional part that compares two or more pieces of CO2 emission reduction information (i.e., two or more users) and outputs the comparison results. The comparison unit 102 compares the CO2 emission reduction information by comparing tags assigned to the CO2 emission reduction information. The comparison results are generated by extracting tags that are common between the CO2 emission reduction information, extracting non-common tags, and comparing the magnitude of actual values ​​between tags for which actual values ​​can be set. Specifically, the comparison unit 102 extracts common tags to extract behaviors that are similar to behaviors that are related to the CO2 emission reduction information of the first user from among behaviors related to the CO2 emission reduction information of the second user. This is done by satisfying conditions such as the number of common tags being equal to or greater than a predetermined value, or the common tags including a predetermined tag, thereby extracting similar behaviors (similar behaviors) from behaviors related to the two pieces of CO2 emission reduction information.

[0062] Furthermore, the comparison unit 102 extracts common tags and non-common tags to extract behaviors related to the second user's CO2 emission reduction information that are not similar to the behaviors related to the first user's CO2 emission reduction information. This is done by satisfying conditions such as the number of non-common tags being equal to or greater than a predetermined value, or the common tags not including a predetermined tag, thereby extracting dissimilar behaviors (dissimilar behaviors) from the behaviors related to the two pieces of CO2 emission reduction information.

[0063] The comparison unit 102 also compares actions related to two pieces of CO2 emission reduction information by extracting common tags and comparing the magnitude of the performance values ​​of tags for which performance values ​​can be set. This is done by extracting similar actions related to two pieces of CO2 emission reduction information in the same way as above, and comparing the magnitude of the performance values ​​for those actions to identify which of the two pieces of CO2 emission reduction information is more effective in reducing CO2 emissions.

[0064] The notification unit 103 is a functional part that transmits a notification indicating that the acquisition unit 101 has acquired the CO2 emission reduction information of the first user to a terminal device owned by the second user. Here, the acquisition unit 101 acquires the CO2 emission reduction information of the first user when it receives an input of the track record of the first user's behavior. In other words, it can be said that the notification unit 103 transmits a notification indicating that it has received an input of the track record of the first user's behavior. The notification regarding the input of the first user by the notification unit 103 is transmitted to the terminal device of the second user. Therefore, the second user can set in advance the first user from whom he or she will receive the notification.

[0065] The notification transmitted by notification unit 103 includes a trigger. When the trigger is turned ON, presentation information, which will be described later, is presented in response to the trigger being turned ON. The trigger is, for example, an access link to a web page showing the presentation information. Turning ON the trigger is, for example, performing an operation to access the access link, and as an example, performing an operation to click (or tap) the access link. Note that the combination of the trigger included in the notification and the ON of the trigger is not limited to this, and any combination may be used as long as the presentation information is presented in response to the trigger being turned ON.

[0066] The presentation unit 104 is a functional part that generates presentation information based on the CO2 emission reduction information of the first user and presents the generated presentation information on a terminal device owned by the second user. The presentation information is, for example, a web page, and is information that allows other users who view the information to understand the decarbonization actions taken by the first user based on the CO2 emission reduction information of the first user. The presentation information includes, for example, a part that is automatically generated from the CO2 emission reduction information of the first user, a part that is generated by voluntary input by the first user, and a part that is generated by the CO2 emission reduction information of the first user and the second user (i.e., viewers of the presentation information). Note that the presentation information is not limited to the web page described above, and may be any information that can at least one of displaying an image on the screen of the terminal device and playing audio from the speaker of the terminal device. Details of the content of the presentation information will be described later along with the operation of the presentation system 100.

[0067] In this way, when a second user views the presented information based on the first user's CO2 emission reduction information, the second user can understand the decarbonization actions taken by the first user, and can reflect on their own decarbonization actions in relation to the decarbonization actions of the first user. As a result, the second user is likely to think, for example, that they cannot let the first user beat them, that they want to take the same actions as the first user, or that they are taking actions from a different perspective than the first user and want to continue. This in turn motivates the second user to start new decarbonization actions or continue their current decarbonization actions, making it easier for them to continue reducing CO2 emissions at the individual level.

[0068] [Operation] Next, the operation of the presentation system 100 will be described with reference to Fig. 3 to Fig. 6. Fig. 3 is a flowchart showing an example of the operation of the presentation system according to the embodiment. Fig. 4 to Fig. 6 are diagrams showing examples of screen displays of the presentation system according to the embodiment.

[0069] The information processing server of the presentation system 100 is always running except during emergencies such as maintenance, and accepts input of CO2 emission reduction information. As shown in FIG. 3, the acquisition unit 101 accepts input of the first user's decarbonization behavior results and acquires CO2 emission reduction information (step S101). Specifically, the acquisition unit 101 accepts input by the first user into an input form including tag selection, and acquires CO2 emission reduction information from the content. Alternatively, the acquisition unit 101 acquires CO2 emission reduction information by automatically assigning tags by language identification from a sentence entered by the first user using free words.

[0070] Meanwhile, the acquisition unit 101 accepts input of the second user's track record of decarbonization actions and acquires CO2 emission reduction information (step S102). Specifically, the acquisition unit 101 accepts input by the second user into an input form, including tag selection, and acquires CO2 emission reduction information from the content of the input. Alternatively, the acquisition unit 101 acquires CO2 emission reduction information by automatically assigning tags to sentences entered by the second user using language identification from free words. Note that steps S101 and S102 do not need to be performed in this order; for example, step S101 may be performed after step S102. As such, the order of steps shown in FIG. 3 is an example, and the steps may be performed in a different order, or another step not shown in FIG. 3 may be performed between steps. Furthermore, some of the steps shown in FIG. 3 are not essential, and such non-essential steps may be omitted.

[0071] Next, the notification unit 103 generates a notification indicating that the CO2 emission reduction information of the first user has been acquired, and transmits the notification to the terminal device of the second user (step S103). Here, FIG. 4 shows how the transmitted notification is presented on the terminal device. FIG. 4(a) shows how the notification is presented when the second user is set to receive a notification indicating that the CO2 emission reduction information of the first user has been acquired. For example, the second user can "follow" a user from among multiple users from whom the second user wishes to receive notifications, and when the second user receives input of the track record of the behavior of the followed user (when the CO2 emission reduction information of the followed user has been acquired), a notification is sent to the terminal device of the second user, and the second user can know that the track record of the behavior of the followed user has been input.

[0072] 4(b) shows a state in which a notification is presented when the presentation system 100 is set to automatically send a notification indicating that the CO2 emission reduction information of the first user has been acquired. For example, when the second user registers with the presentation system 100, the second user can input user attribute information, etc. In the presentation system, users with common attribute information are automatically set as one community (group), and all users in the community other than the second user are set as first users. Therefore, when the input of the track record of the activity of a user in the community other than the second user is received (when the CO2 emission reduction information of a user in the community other than the second user is acquired), a notification is sent to the terminal device of the second user, and the second user can know that the track record of the activity of a user in the community other than the second user has been input. A community is automatically set, for example, by family users who share all of the addresses in the attribute information, or by users in a region who share part of the addresses. A community may also be automatically set by users in a company (school) who share the same workplace (school) in the attribute information. A community may also be automatically set by users of the same generation who share the same age in the attribute information.

[0073] Incidentally, if each member of a family is a user of the presentation system 100, i.e., a user of the decarbonization system, points are awarded by obtaining CO2 emission reduction information using the HEMS in the same home and calculating the points to be awarded. In this case, points can be awarded to the head of the household or to family members by setting a household head or by setting up point sharing within the family. On the other hand, even within a family, if CO2 emission reductions are achieved solely through the actions of an individual, points can be awarded to that individual without being attributed to the family.

[0074] As shown in Fig. 4, the sent notification includes an access link for "View Post." Clicking or tapping on this access link turns on the trigger. As shown in Fig. 3, in determining whether the trigger has been turned on (step S104), if it is determined that the access link has been clicked or tapped and the trigger has been turned on (Yes in step S104), the process proceeds to step S105, and if the access link has not been clicked or tapped and the trigger has not been turned on (No in step S104), the process ends.

[0075] In step S105, the comparison unit 102 compares the CO2 emission reduction information between the first user and the second user. Then, the presentation unit 104 generates presentation information including the comparison result by the comparison unit 102 and presents it to the terminal device of the second user (step S106).

[0076] FIG. 5 shows how presented information is presented on a terminal device. FIG. 5 shows presented information when a first user, "User A," inputs a record of decarbonization behavior, in which the "set temperature" in cooling mode of the "air conditioner" is changed by "1°C" toward energy saving. Here, User A can input comments (subjective impressions, etc.) along with the record of decarbonization behavior. Such comments are then presented as is in the presented information. In other words, the second user can learn the first user's record of decarbonization behavior as well as their impressions, etc., through the comments.

[0077] Furthermore, some of the tags for the CO2 emission reduction information (here, "air conditioner" and "set temperature") are included as they are in the presented information. As a result, for example, a user who is not following such an input by the first user can search for the input by relying on the tags and request presentation. In this way, even a user who has not formed a community such as following can rely on the tags to find a first user who has similar CO2 emission reduction information, and can join the community by following the first user, for example.

[0078] 5A and 5B, the comparison results included in the presented information are different. In FIG. 5A, the comparison result includes information on similar behaviors, which is extracted from among the behaviors related to the CO2 emission reduction information of the second user that are similar to the behaviors related to the CO2 emission reduction information of the first user. As described above, the comparison unit 102 extracts common tags to extract behaviors similar to the behaviors related to the CO2 emission reduction information of the first user from among the behaviors related to the CO2 emission reduction information of the second user. For example, in FIG. 5A, the second user also changed the set temperature of the air conditioner, and conditions are met such as the number of common tags being equal to or greater than a predetermined value (here, two) or the common tags including predetermined tags (here, "air conditioner" and "set temperature"). Therefore, the similar behavior of the second user to the first user is presented as "The set temperature of the air conditioner has been changed."

[0079] In addition, a comparison based on the CO2 emission reduction information of the first and second users shows that there is similar behavior between the first user and the second user, and therefore recommendation information is presented recommending that the efforts of the first user (user A) may be used as a reference for the efforts of the second user.

[0080] On the other hand, in (b) of FIG. 5, the comparison result includes information on dissimilar behaviors, which are extracted from among the behaviors related to the CO2 emission reduction information of the second user that are not similar to the behaviors related to the CO2 emission reduction information of the first user. As described above, the comparison unit 102 extracts common tags and non-common tags to extract, from among the behaviors related to the CO2 emission reduction information of the second user, behaviors that are not similar to the behaviors related to the CO2 emission reduction information of the first user. For example, in (b) of FIG. 5, the second user has not changed the set temperature of the air conditioner, and the number of non-common tags is equal to or greater than a predetermined value (here, 2), or the common tags do not include predetermined tags (here, "air conditioner" and "set temperature"). Therefore, the dissimilar behavior of the second user relative to the first user is displayed as "The set temperature of the air conditioner has not been changed."

[0081] Furthermore, a comparison based on the CO2 emission reduction information of the first user and the second user indicates that there are dissimilar actions between the first user and the second user, and therefore, recommendation information is presented recommending that the efforts of the first user (user A) may be used as a reference for the efforts of the second user. Note that, as described above, the recommendation information may not be based on the CO2 emission reduction information of the first user and the second user, but may be a recommended action based solely on the CO2 emission reduction information of the first user (e.g., what aspects of the first user's actions should be taken into consideration), a recommended action based solely on the CO2 emission reduction information of the second user (e.g., what aspects of the second user's actions should be improved), or information regarding a recommended action from the operator of the decarbonization system or a participating company, without relying on the CO2 emission reduction information.

[0082] Furthermore, such comparison results and recommendation information do not necessarily need to be included in the presented information. For example, the presented information presented on the terminal device shown in FIG. 6 is presented when a first user, “User A,” inputs a record of decarbonization behavior, similar to that shown in FIG. 5, indicating that the first user has changed the “temperature setting” of the “air conditioner” in cooling mode by “1°C” toward energy conservation. The difference from FIG. 5 is that the presented information shown in FIG. 6 links the presentation based on the first user’s (User A’s) CO2 emission reduction information with the presentation of the change in the “temperature setting” of the “air conditioner” (information based on the second user’s CO2 emission reduction information) made by the second user (User B or User C) who received the presentation. In other words, the first user’s actions and the actions taken by the second user as a result of the presentation are displayed in a list. This allows the first user to view the presented information regarding their decarbonization behavior and understand the impact of their actions on the second user. This allows the first user to further reflect on their own actions and more easily practice more appropriate decarbonization behavior.

[0083] In this way, by allowing a second user to view the presented information based on the first user's CO2 emission reduction information, the second user can understand the decarbonization actions taken by the first user, allowing the viewer to reflect on their own decarbonization actions in relation to the first user's decarbonization actions. As a result, the second user is likely to think, for example, that they cannot be outdone by the first user, that they want to take similar actions as the first user, or that they want to continue their current decarbonization actions because they have taken them from a different perspective than the first user. This motivates the second user to start new decarbonization actions or continue their current decarbonization actions, making it easier to continue reducing CO2 emissions at an individual level. Furthermore, by making the CO2 emission reduction information of the decarbonization actions taken by the second user available to the first user, the first user is likely to think, for example, that they cannot be outdone by the second user, that they want to take similar actions as the second user, or that they want to continue their current decarbonization actions because they have taken them from a different perspective than the second user. This motivates the first user to start new decarbonization actions or continue their current decarbonization actions, making it easier to continue reducing CO2 emissions at an individual level.

[0084] [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 first user who is performing decarbonization behavior, and a presentation unit 104 that presents presentation information based on the CO2 emission reduction information of the first user on a terminal device owned by a second user.

[0085] In this presentation system 100, a second user can view presentation information based on the first user's CO2 emission reduction information via a terminal device that presents the information, allowing the second user to understand the decarbonization actions taken by the first user. Therefore, the second user may be tempted to think, "I can't let myself be outdone by the first user," "I want to take the same actions as the first user," or "I want to take actions from a different perspective than the first user," etc. This may motivate the second user to start new decarbonization actions or continue their current decarbonization actions, thereby increasing their motivation to engage in decarbonization actions at an individual level.

[0086] Furthermore, the presentation system 100 in the second aspect is the presentation system 100 described in the first aspect, and the acquisition unit 101 acquires CO2 emission reduction information of the first user by accepting input of the first user's track record of decarbonization behavior.

[0087] According to this, by accepting input of the actual results, it is possible to acquire the CO2 emission reduction information of the first user.

[0088] 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 notification unit 103 that sends a notification to the terminal device indicating that the CO2 emission reduction information of the first user has been acquired, and the presentation unit 104 presents the presentation information when a trigger included in the notification is turned ON.

[0089] This allows the terminal device of the second user to receive and display the transmitted notification, and the presented information can be presented at the second user's will by being triggered by the second user's action of turning on a trigger included in the notification.

[0090] Furthermore, the presentation system 100 in a fourth aspect is the presentation system 100 described in any one of the first to third aspects, in which the second user performs decarbonization behavior, the acquisition unit 101 further acquires CO2 emission reduction information regarding the second user's performance in the behavior, the presentation system 100 includes a comparison unit 102 that compares the CO2 emission reduction information of the first user and the second user, and the presentation information includes the comparison result by the comparison unit 102.

[0091] This makes it possible to present information including the results of a comparison between the CO2 emission reduction information of the first user and the second user.

[0092] Furthermore, the presentation system 100 in the fifth aspect is the presentation system 100 described in the fourth aspect, and the comparison result includes information on similar behaviors extracted from among the behaviors related to the CO2 emission reduction information of the second user that are similar to the behaviors related to the CO2 emission reduction information of the first user.

[0093] This makes it possible to present information including a comparison result that includes information about similar behaviors.

[0094] Furthermore, the presentation system 100 in the sixth aspect is the presentation system 100 described in the fourth aspect, and the comparison result includes information on dissimilar behaviors, which are behaviors related to the CO2 emission reduction information of the second user that are not similar to the behaviors related to the CO2 emission reduction information of the first user.

[0095] This makes it possible to present information including a comparison result that includes information about dissimilar behaviors.

[0096] Furthermore, the presentation system 100 in a seventh aspect is the presentation system 100 according to any one of the first to sixth aspects, and the presentation information includes recommendation information relating to decarbonization actions recommended to the second user.

[0097] This makes it possible to present presentation information including recommendation information regarding decarbonization actions recommended to the second user.

[0098] Furthermore, the presentation system 100 according to an eighth aspect is the presentation system 100 according to the seventh aspect, in which the recommendation information is determined based on CO2 emission reduction information of the first user.

[0099] This makes it possible to present presentation information including recommended information determined based on the CO2 emission reduction information of the first user.

[0100] Furthermore, the presentation system 100 in the ninth aspect is the presentation system 100 described in the eighth aspect, in which the second user performs decarbonization behavior, the acquisition unit 101 further acquires CO2 emission reduction information regarding the second user's performance in the behavior, and the recommended information is determined based on the CO2 emission reduction information of the first user and the second user.

[0101] This makes it possible to present presentation information including recommended information determined based on the CO2 emission reduction information of the first and second users.

[0102] In addition, the presentation method in the tenth aspect is a presentation method executed by a computer, and includes the steps of obtaining CO2 emission reduction information regarding the performance of a first user who is performing decarbonization behavior, and presenting presentation information based on the CO2 emission reduction information of the first user on a terminal device owned by a second user.

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

[0104] Furthermore, a program according to an eleventh aspect is a program for causing a computer to execute the presentation method described above.

[0105] This allows the computer to achieve the same effects as the presentation system described above.
