[0004] However, there is still room for improvement in the technology for outputting an emissions score for a user's greenhouse gas emissions. [Means for solving the problem]

[0005] According to one aspect of the present invention, there is provided an information processing system. The information processing system includes at least one processor, and the at least one processor is configured to execute a program to perform the following steps: In the acquisition step, first transaction information regarding a transaction between a user and a business partner is acquired. The first transaction information includes information regarding an amount of expenditure paid by the user to the business partner and information regarding the business partner.

[0008] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings. Various features shown in the following embodiments can be combined with each other.

[0009] Incidentally, the program for realizing the software appearing in this embodiment may be provided as a non-transitory computer-readable medium, or may be provided so that it can be downloaded from an external server, or may be provided so that the program is started on an external computer and its functions are realized on a client terminal (so-called cloud computing).

[0010] In this embodiment, the term "unit" may also include, for example, a combination of hardware resources implemented by a circuit in the broad sense and software information processing that can be specifically realized by these hardware resources. In addition, this embodiment handles various types of information, which may be represented by, for example, physical values of signal values representing voltages and currents, high and low signal values as a binary bit set consisting of 0 or 1, or quantum superposition (so-called quantum bits), and communication and calculations may be performed on a circuit in the broad sense.

[0011] In addition, a circuit in the broad sense is a circuit realized by at least appropriately combining a circuit, circuitry, a processor, a memory, etc. That is, it includes an application specific integrated circuit (ASIC), a programmable logic device (e.g., a simple programmable logic device (SPLD), a complex programmable logic device (CPLD), and a field programmable gate array (FPGA)), etc.

[0012] 1. Hardware Configuration This section explains the hardware configuration.

[0013] <Information Processing System 1> FIG. 1 is a configuration diagram showing an information processing system 1. The information processing system 1 includes an information processing device 2 and a user terminal 3. The information processing device 2 and the user terminal 3 are configured to be able to communicate with each other via a telecommunications line. In one embodiment, the information processing system 1 is made up of one or more devices or components. For example, if the information processing system 1 is made up of only the information processing device 2, the information processing system 1 can be the information processing device 2. These components will be described below.

[0014] <Information processing device 2> 2 is a block diagram showing the hardware configuration of the information processing device 2. The information processing device 2 includes a communication unit 21, a storage unit 22, and a processor 23, and these components are electrically connected via a communication bus 20 inside the information processing device 2. Each component will be further described.

[0015] The communication unit 21 is preferably a wired communication means such as USB, IEEE1394, Thunderbolt (registered trademark), wired LAN network communication, etc., but may also include wireless LAN network communication, mobile communication such as 3G / LTE / 5G, BLUETOOTH (registered trademark) communication, etc. as needed. In other words, it is more preferable to implement it as a collection of multiple communication means. In other words, the information processing device 2 may communicate various information from the outside via the communication unit 21 and the network.

[0016] The storage unit 22 stores various pieces of information defined above. This can be implemented, for example, as a storage device such as a solid state drive (SSD) that stores various programs and the like related to the information processing device 2 executed by the processor 23, or as a memory such as a random access memory (RAM) that stores temporarily required information (arguments, arrays, etc.) related to the program operations. The storage unit 22 stores various programs, variables, etc. related to the information processing device 2 executed by the processor 23.

[0017] The processor 23 processes and controls the overall operations related to the information processing device 2. The processor 23 is, for example, a central processing unit (CPU) not shown. The processor 23 realizes various functions related to the information processing device 2 by reading out predetermined programs stored in the storage unit 22. In other words, information processing by software stored in the storage unit 22 is specifically realized by the processor 23, which is an example of hardware, and can be executed as each functional unit included in the processor 23. These will be described in more detail in the next section. Note that the processor 23 is not limited to being single, and multiple processors 23 may be provided for each function. A combination of these may also be used.

[0018] The processor 23 is configured to be able to acquire information from the user terminal 3 or other devices. The processor 23 is configured to be able to acquire various pieces of information by reading out various pieces of information stored in a storage area that is at least a part of the memory unit 22 and writing the read out information in a working area that is at least a part of the memory unit 22. The storage area is, for example, an area of the memory unit 22 that is implemented as a storage device such as an SSD. The working area is, for example, an area that is implemented as a memory such as a RAM. Note that acquisition by the processor 23 includes acquiring output results from each functional unit included in the processor 23.

[0019] The processor 23 is configured to be able to display various types of information. The information can be presented to the user via the display unit 34 of the user terminal 3 or another device. In such a case, for example, the processor 23 controls the display unit 34 of the user terminal 3 to display visual information such as a screen, an image including a still image or a video, an icon, or a message. The processor 23 may generate only rendering information for displaying the visual information on the user terminal 3. Note that the processor 23 may present the output information to the user without going through the user terminal 3 or another device user.

[0020] <User terminal 3> 3 is a block diagram showing the hardware configuration of the user terminal 3. The user terminal 3 includes a communication unit 31, a storage unit 32, a processor 33, a display unit 34, and an input unit 35, and these components are electrically connected via a communication bus 30 inside the user terminal 3. The description of the communication unit 31, the storage unit 32, and the processor 33 is omitted because they are the same as the description of each unit in the information processing device 2.

[0021] The display unit 34 may be included in the housing of the user terminal 3 or may be externally attached. The display unit 34 displays a graphical user interface (GUI) screen that can be operated by the user. This is preferably implemented by selectively using display devices such as a CRT display, a liquid crystal display, an organic EL display, or a plasma display depending on the type of user terminal 3.

[0022] The input unit 35 is configured to be able to accept input from a user. The input unit 35 may be included in the housing of the user terminal 3 or may be externally attached. For example, the input unit 35 may be implemented as a touch panel integrated with the display unit 34. The touch panel allows the user to input tapping, swiping, and the like. Of course, instead of a touch panel, a switch button, a mouse, a QWERTY keyboard, a voice recognition device, a gesture detection device, a gaze detection device, a biosignal detection device, an imaging device, and the like may be used. That is, the input unit 35 accepts an operation input made by the user. In response, the input unit 35 transfers a signal corresponding to the operation input to the processor 33 via the communication bus 30. The processor 33 can execute predetermined control and calculations as necessary.

[0023] 2. Information Processing In this section, the information processing executed in the information processing system 1 described above will be described.

[0024] 2.1. Information processing flow 4 is an activity diagram showing an example of the flow of information processing executed in the information processing system 1. Note that the information processing may include any exception processing not shown. Exception processing includes interruption of the information processing or omission of each process. Selection or input performed in the information processing may be based on a user operation or may be performed automatically without relying on a user operation.

[0025] [Activity A1] First, in activity A1, the information processing system 1 performs a login process in response to a user operation. As a result, the processor 23 acquires user information of the user who logs in to the processor 33.

[0026] [Activity A2] Next, processor 23 executes a linking process with the information source in response to a user's operation via processor 33. The information source is configured to store first transaction information. The first transaction information indicates, among other things, information regarding the fulfillment of credit and debt in a transaction, particularly monetary information. The first transaction information includes information regarding the amount of expenditure paid by the user to the business partner and information regarding the business partner. For example, the information regarding the business partner is information configured to identify the business partner, and may include, for example, the business partner's name, identification number, telephone number, etc. The information source for such first transaction information may be any information source that can contain the first transaction information, such as account information for a bank account, a credit card statement, a prepaid payment statement, or a cashless payment statement. Therefore, a transaction is not limited to a direct payment between a user and a business partner, such as a cash payment transaction, but may also include a payment transaction that is settled using a payment method operated by an operator other than the user and the business partner. For convenience of explanation, the information source linked in this information processing will be treated below as account information (e.g., information listed in a passbook) of the bank account used by the user for the transaction. In this case, the process of linking with the bank account as the information source involves, for example, performing access authentication through an authentication API provided by the bank.

[0027] [Activity A3] If the authentication is completed, in activity A3, processor 23 becomes able to acquire account information of the bank account. As a result, processor 23 acquires first transaction information between the user and the business partner, such as the transaction date and time, the transaction amount (e.g., the transfer amount), and information about the business partner (e.g., the name of the transfer recipient, the account number, etc.). In this embodiment, processor 23 acquires first transaction information about the transaction by linking a payment method such as a bank account to user information about the user. Here, the account information includes information about the monetary exchange related to the transaction, but does not include product information that can identify the product provided by the business partner to the user. Note that "products" are not limited to tangible objects but can also include intangible objects. For example, products include any object that can be the subject of a commercial transaction, such as movable property, real estate, electronic information goods, the provision of services, and debts such as stocks. Product information is any information that can identify the content of the product. Product information is information that is difficult for anyone other than the parties to the transaction to obtain without the consent of the parties, such as the product number, the quantity of the product, and the content of the service. The product information may be included in, for example, receipts (including electronic receipts), invoices, bills, contracts, etc. issued between the parties.

[0028] [Activity A4] Next, in activity A4, processor 23 identifies the emission coefficient of the trading partner identified from the first transaction information based on reference coefficient information that indicates a predetermined correspondence between business entities and emission coefficients. The reference coefficient information is configured based on publicly available information. If a business entity has published its own emission coefficient in SCOPE3 or the like, the reference coefficient information is configured by associating the emission coefficient with the business sector. The reference coefficient information may also include a correspondence between industry and emission coefficient. By using this correspondence, for example, if the business entity's own emission coefficient cannot be obtained from publicly available information, the business sector (e.g., manufacturing, retail, transportation, etc.) can be identified based on the business entity's registration information or company website, and the emission coefficient corresponding to the identified industry can be used as the business entity's emission coefficient.

[0029] [Activity A5] Next, in activity A5, processor 23 calculates the greenhouse gas emissions corresponding to the transaction based on the identified emission coefficient. For example, processor 23 calculates the greenhouse gas emissions corresponding to the transaction by multiplying the user's expenditure amount in the transaction by the emission coefficient of the business entity. Note that the emission coefficient in the reference coefficient information is averaged for the business entity as a whole. Therefore, it should be noted that if the emission coefficient is used and there are specific circumstances related to each transaction of the business entity, such as the product being manufactured using particularly carbon-neutral materials or methods, there is a possibility that the calculated greenhouse gas emissions may differ from the actual greenhouse gas emissions in each transaction.

[0030] Then, in activity A5, when processor 23 acquires first transaction information, it outputs a first emission score as an emission score based on the first transaction information. The emission score is the amount of greenhouse gas emissions related to the transaction. The emission score can be any index, such as the emission amount itself, a normalized value of the emission amount, the amount of greenhouse gas reduction compared to the amount of greenhouse gas emissions relative to a reference state, or a weighted average of the greenhouse gas emissions of each transaction. In this embodiment, processor 23 causes display unit 34 to display home screen 4 (see FIG. 5 ), which displays the first emission score, which is the latest emission score at this point in time.

[0031] In this way, processor 23 can output an emission score through processing activities A1 to A5. The emission score may be output as an individual index for each transaction, or as an index for all transactions conducted by the user. As described above, the greenhouse gas emissions calculated based on the first transaction information may not take into account the circumstances of each transaction, and therefore the first emission score may deviate from the actual emission score.

[0032] Next, processor 23 outputs a second emission score as the emission score based on the second transaction information through the processing of activities A11 to A17. The flow of information processing for calculating the second emission score will be described below.

[0033] The second transaction information includes information related to the transaction that is not included in the first transaction information. For example, the second transaction information may be configured to improve the reliability of greenhouse gas emissions associated with the transaction. The second transaction information also includes product information that can identify the product provided to the user by the trading partner. Specifically, the product information may include items related to greenhouse gas emissions, such as the quantity of the product and the product details (e.g., raw materials, manufacturing method, delivery method, contract plan, etc.). The second transaction information may be configured not to be shared with the operator during the payment transaction. This configuration provides an incentive for users to voluntarily provide the second transaction information, which cannot be obtained by simply linking payment methods, making it easier to obtain a more reliable emission score than when using only the first transaction information.

[0034] The operator is, for example, a bank if the source of the first transaction information is account information for a bank account, a credit card issuer if the source of the first transaction information is a credit card statement, or an operator of the prepaid payment if the source of the first transaction information is a statement for a prepaid payment such as a cashless payment. The specific form of the second transaction information is arbitrary, but the second transaction information can be obtained, for example, from a source of electronic data of the second transaction information, such as electronic data related to the transaction such as an electronic receipt or an electronic contract, or a source in which paper media related to the transaction such as a paper receipt or a paper contract have been electronically converted by photographing it, etc.

[0035] [Activity A11] First, in activity A11, processor 23 identifies the business type of the business partner based on, for example, the first transaction information. For example, processor 23 identifies the business type of the business partner based on the name of the business partner included in the first transaction information. Specifically, if the name of the business partner indicates an electric power company, processor 23 identifies the business type of the business partner as an electric power-related business type, such as "electric power sector" or "electric power company."

[0036] [Activity A12] Next, in activity A12, processor 23 presents to the user candidates for acceptable second transaction information according to the business type of the business partner identified based on the first transaction information. For example, if the business type of the business partner is identified as an electric power company, in other words, if the business partner is an electric power company, processor 23 presents a meter reading slip for the electricity used by the user as one of the candidates for the second transaction information. This configuration can encourage the user to take voluntary action to output a highly reliable emission score, particularly for electricity, which is an important source of greenhouse gas emissions.

[0037] [Activity A13] Next, in activity A13, processor 23 accepts input of second transaction information. If acceptable second transaction information candidates are presented in activity A12, processor 23 may accept input of at least one of the candidates. Thereafter, the user imports second transaction information into information processing device 2 through user terminal 3. For example, if acceptable second transaction information candidates are presented in activity A12, processor 23 accepts input of at least the presented second transaction information from the user. With this configuration, by presenting to the user what information to input as second transaction information, it is possible to encourage the user to provide information with less burden. Of course, input other than the presented second transaction information candidates may also be accepted from the user. Note that accepting input of second transaction information includes transmitting rendering information that allows processor 33 to display an acceptable screen (e.g., home screen 4 or details screen 5 described below) on display unit 34, and accepting from processor 33 second transaction information input to processor 33 via display unit 34.

[0038] [Activity A14] Furthermore, if input of second transaction information is accepted, in activity A14, processor 23 grants an input benefit to the user. The input benefit is a benefit that is granted regardless of the content of the second transaction information entered. With this configuration, an incentive can be given to the user for simply entering second transaction information, thereby improving the efficiency of collecting second transaction information.

[0039] [Activity A15] Next, in activity A15, processor 23 calculates greenhouse gas emissions associated with the transaction based on at least the second transaction information. For example, processor 23 calculates greenhouse gas emissions associated with the transaction based on the expenditure amount and product information using reference information indicating the relationship between the unit quantity of the product and greenhouse gas emissions. Note that processor 23 may also calculate greenhouse gas emissions associated with the transaction based on the first transaction information and the second transaction information. In this case, for example, processor 23 may perform a process of correcting the greenhouse gas emissions calculated based on the first transaction information based on the second transaction information.

[0040] [Activity A16] Next, in activity A16, processor 23 outputs a second emission score as the emission score based on at least the second transaction information. The calculation method for the second emission score is the same as that for the first emission score. For example, processor 23 may output the second emission score based on the greenhouse gas emissions calculated based on the expenditure amount and product information using reference information indicating the relationship between the unit quantity of the product and the greenhouse gas emissions. This configuration makes it easier to output a more reliable emission score that takes into account the relationship between the product or service and the environmental contribution activity, which is difficult to identify based on the transaction history via the payment instrument, such as the transaction amount or the business partner. In this embodiment, processor 23 updates the emission score from the first emission score to the second emission score. In other words, in this information processing, processor 23 prioritizes the second emission score over the first emission score as a more accurate emission score. Furthermore, the calculation of the second emission score may be performed independently of the calculation of the first emission score. In addition, the processor 33 may calculate the second emission score without using the first transaction information. In addition, the processor 33 may calculate the second emission score by correcting the first emission score based on the second transaction information.

[0041] [Activity A17] Next, in activity A17, the processor 23 grants a first reward to the user based on the second transaction information. This configuration provides the user with an incentive to provide more information to improve the reliability of greenhouse gas emissions, making it easier for the user to voluntarily cooperate and obtain a more reliable emission score. For example, the processor 23 grants the first reward, an example of a reward, based on the difference between the first emission score and the second emission score. This configuration provides the user with an incentive to provide more important information in the second transaction information for improving the reliability of the emission score, making it easier to output a more reliable emission score. For example, the processor 23 may determine that the reliability of the emission score has improved significantly as the difference between the first emission score and the second emission score increases, and may grant a more advantageous reward based on the degree of improvement in reliability. The processor 23 may also grant the first reward based on the type or number of second transaction information. This configuration encourages the user to provide a greater variety or number of second transaction information, making it easier to output a more complete and reliable emission score. For example, processor 23 may grant a first benefit depending on the type or number of second transaction information items that have been input from among the presented second transaction information candidates. In this embodiment, when processor 23 receives second transaction information, it grants a first benefit that is more advantageous than when only first transaction information is acquired. This configuration can strengthen the incentive to input second transaction information. Note that the first benefit may be a combination of the various granting modes described above. Furthermore, if the input of second transaction information cannot be confirmed, the processing of activities A11 to A17 is omitted.

[0042] In this way, the information processing can be configured to introduce various mechanisms to encourage users to provide second transaction information, thereby improving the reliability of the emission score.

[0043] Next, processor 23 updates the release score output in activity A15 or activity A16 based on the user environment information through the processing of activities A21 to A23. The flow of information processing for updating the release score based on the user environment information will be described below.

[0044] First, user environmental information is information about a user's lifestyle habits or environmental values. Information about lifestyle habits may include, for example, information about commuting, such as commuting means and commuting time, information about how to use home appliances, and information about purchasing goods, such as purchasing methods. Information about values may include any information that may suggest environmental awareness, such as awareness of environmental issues, knowledge of environmental countermeasures, and environmental efforts in daily life. User environmental information may include subjective information about the user, such as preferences, environmental awareness, and daily habits. With this configuration, information that does not appear solely in transactions can be reflected in the emission score.

[0045] [Activity A21] First, in activity A21, processor 23 accepts input of user environment information. For example, processor 23 causes processor 33 to display on display unit 34 a question and answer screen 6 capable of accepting input of user environment information.

[0046] [Activity A22] When the input of the user environmental information is accepted, in activity A22, the processor 23 further updates the first emission score or the second emission score based on the user environmental information. For example, the processor 23 updates the second emission score, which is an example of the latest emission score, so that the more environmentally friendly the user's lifestyle habits or environmental values, the better. Note that if the processor 23 determines that the greenhouse gas emissions themselves tend to be low, the processor 23 may update the greenhouse gas emissions themselves.

[0047] [Activity A23] Next, in activity A23, processor 23 grants a second reward to the user based on the user environment information. This configuration allows an incentive to be given for self-reporting subjective information about the user's environment, which is difficult to determine from transaction information alone, making it easier to calculate a more reliable emission score that better reflects the user's personal behavior. For example, processor 23 may grant the second reward in a manner similar to that of activity A17, using the first emission score in activity A17 as the emission score before update and the second emission score in activity A17 as the emission score after update.

[0048] [Activity A31] Then, in activity A31, processor 23 displays home screen 4 showing the latest release score on display unit 34. If user environment information is not input, activities A22 and A23 are skipped and activity A31 is executed. After activity A31, this information processing ends.

[0049] 3. Details of data processing In this section, the details of the above-mentioned information processing will be explained along with screen examples.

[0050] 5 is a diagram showing an example of a home screen 4. The home screen 4 is configured to allow a user to visually check an overview of their emission score. The home screen 4 includes a score display area 41, an emission amount display area 42, a confirmation button 43, and an information input button 44.

[0051] The score display area 41 is configured to allow the latest discharge score to be visually confirmed, and may include, for example, an indicator corresponding to the discharge score and the value of the discharge score.

[0052] The emission amount display area 42 is configured to display quantitative values relating to greenhouse gases, such as greenhouse gas emissions and carbon offset amounts.

[0053] The confirmation button 43 is a button for displaying a details screen 5, which will be described later.

[0054] The information input button 44 is a button for displaying a screen that allows the reception of second transaction information.

[0055] The question and answer button 45 is a button for displaying a question and answer screen 6, which will be described later.

[0056] 6 is a diagram showing an example of the details screen 5 as a screen example. The details screen 5 is configured to allow confirmation of details of the transaction history based on the first transaction information. As shown in FIG. 6, the details screen 5 includes a list screen 51, an add information button 52, a question and answer button 53, and a back button 54.

[0057] The list screen 51 is configured so that each transaction of the first transaction information can be associated with the greenhouse gas emission amount and can be grasped.

[0058] The add information button 52 is a button for displaying a screen for inputting second transaction information when there are candidates for the second transaction information that can be input. For example, one of the add information buttons 52 is configured to indicate that one of the second transaction information that can be input is a "meter reading slip" because the business partner is "Power Company A" and its industry is the electricity business. Another of the add information buttons 52 is configured to indicate that one of the second transaction information that can confirm the contents of the purchased product is an "electronic receipt" because the business partner is an e-commerce site called "AM Shopping" and its industry is "sales." When these add information buttons 52 are operated, the processor 23 causes the display unit 34 to display a screen for inputting the second transaction information.

[0059] The question and answer button 53 is a button for displaying the question and answer screen 6, similar to the question and answer button 45.

[0060] The back button 54 is a button for displaying the home screen 4 again when operated.

[0061] 7 is a diagram showing an example of a question and answer screen 6. The question and answer screen 6 is configured to be able to accept input of information about the user's commute as user environment information. As shown in FIG. 7, the question and answer screen 6 includes an answer field 61, a benefit display field 62, and a send button 63.

[0062] The answer field 61 includes a question indicating the user environment information to be input, and a field where the user environment information can be input.

[0063] The benefit display field 62 is configured to display the input status in the displayed answer field 61 and points as a benefit (second benefit) to be awarded in response to the input. The higher the response rate, the higher the points to be awarded.

[0064] The send button 63 is a button for sending the answer entered in the answer field 61, in other words, the user environment information, from the processor 33 to the processor 23.

[0065] 4.Other The above embodiment may be modified as follows.

[0066] The information processing device 2 may be an on-premise type or a cloud type. As the information processing device 2 in the cloud type, the above-mentioned functions and processes may be provided in the form of, for example, SaaS (Software as a Service) or cloud computing.

[0067] In the above embodiment, the information processing device 2 performs various storage and control operations, but multiple external devices may be used instead of the information processing device 2. That is, various information and programs may be distributed and stored in multiple external devices using block chain technology or the like.

[0068] The above embodiment is not limited to the information processing system 1, and may be an information processing method or an information processing program. The information processing method includes each step of the information processing system 1. The information processing program causes at least one computer to execute each step of the information processing system 1.

[0069] The information processing system 1 and the like may be provided in the following aspects.

[0070] (1) An information processing system, comprising at least one processor, configured to execute a program to perform the following steps: an acquisition step acquires first transaction information relating to a transaction between a user and a business partner, the first transaction information including information on an amount of expenditure paid by the user to the business partner and information on the business partner; a first reception step accepts input of second transaction information relating to the content of the transaction with the business partner, which is possessed by at least the user; the second transaction information including greenhouse gas emissions related to the transaction; and an information processing system configured to improve the reliability of greenhouse gas emissions attributable to the user who conducted the transaction, wherein in a first output step, when the first transaction information is acquired, a first emission score is output as an emission score related to greenhouse gas emissions attributable to the user who conducted the transaction based on the first transaction information; in a second output step, when input of the second transaction information is further accepted, a second emission score is output as the emission score based on at least the second transaction information; and in an awarding step, when input of the second transaction information is accepted, a first benefit is awarded to the user based on the second transaction information.

[0071] This configuration provides users with an incentive to provide more information to improve the reliability of greenhouse gas emissions, making it easier to obtain more reliable emission scores through voluntary cooperation from users.

[0072] (2) In the information processing system described in (1) above, the transaction includes a payment transaction that is settled using a payment method operated by an operator other than the user and the trading partner, the second transaction information is configured not to be shared with the operator at the time of the payment transaction, and in the acquisition step, the first transaction information regarding the transaction is acquired by linking the payment method to user information regarding the user.

[0073] With this configuration, users are given an incentive to voluntarily provide second transaction information that cannot be obtained by simply linking payment methods, making it easier to obtain a more reliable emission score than when only the first transaction information is used.

[0074] (3) In the information processing system described in (2) above, the second transaction information includes product information that can identify products provided to the user by the business partner, and in the second output step, the second emission score is output based on the greenhouse gas emissions calculated based on the expenditure amount and the product information using reference information that indicates the relationship between the unit quantity of the product and the greenhouse gas emissions.

[0075] This configuration makes it easier to output a more reliable emissions score that takes into account the relationship between the product or service and the environmental contribution activity, which is difficult to identify based on transaction history via payment methods, such as transaction amount or trading partner information alone.

[0076] (4) In the information processing system described in any one of (1) to (3) above, in the presentation step, acceptable candidates for the second transaction information are presented to the user according to the business type of the trading partner identified based on the first transaction information, and in the first reception step, input of at least the presented candidates for the second transaction information is received from the user.

[0077] According to this configuration, by presenting to the user what information to input as the second transaction information, it is possible to encourage the user to provide information in a manner that is less burdensome for the user.

[0078] (5) In the information processing system described in (4) above, in the presentation step, if the customer is an electric power company, a meter reading slip for the electricity used by the user is presented as one of the candidates for the second transaction information.

[0079] With this configuration, it is possible to encourage the user to take voluntary action to output a highly reliable emission score, particularly with regard to electricity, which is an important source of greenhouse gas emissions.

[0080] (6) In the information processing system described in any one of (1) to (5) above, the granting step includes a first granting step, in which the first benefit is granted depending on the difference between the first release score and the second release score.

[0081] With this configuration, users can be given an incentive to provide information that is more important in improving the reliability of the emission score among the second transaction information, making it easier to output a more reliable emission score.

[0082] (7) An information processing system according to any one of (1) to (6) above, wherein the granting step includes a second granting step, and in the second granting step, the first benefit is granted depending on the type or number of the second transaction information.

[0083] According to this configuration, the user can be encouraged to provide a greater variety or quantity of second transaction information, which makes it easier to output a more reliable emission score without any omissions.

[0084] (8) In the information processing system described in any one of (1) to (7) above, in the granting step, when the second transaction information is accepted, a more advantageous benefit is granted as the first benefit than when only the first transaction information is acquired.

[0085] This configuration can provide a stronger incentive to input the second transaction information.

[0086] (9) In the information processing system described in any one of (1) to (8) above, in a second reception step, input of user environment information, which is information regarding the user's lifestyle habits or values regarding the environment, is received, and in an update step, when input of the user environment information is received, the first emission score or the second emission score is further updated based on the user environment information, and the granting step further includes a third granting step, and in the third granting step, a second benefit is further granted to the user based on the user environment information.

[0087] With this configuration, it is possible to provide incentives for users to self-report subjective information about the environment, which is difficult to determine from transaction information alone, making it easier to calculate a more reliable emission score that better reflects the user's individual behavior.

[0088] (10) An information processing method, comprising the steps of the information processing system according to any one of (1) to (9) above.

[0089] (11) A program that causes at least one computer to execute each step of the information processing system according to any one of (1) to (9) above. Of course, this is not the case.

[0090] Finally, while various embodiments of the present disclosure have been described, they are presented as examples and are not intended to limit the scope of the invention. The novel embodiments may be embodied in various other forms, and various omissions, substitutions, and modifications may be made without departing from the spirit of the invention. Such embodiments and modifications are intended to be included within the scope and spirit of the invention, as well as within the scope of the inventions and their equivalents as defined in the claims.
