[0012] An embodiment of the greenhouse gas emission calculation system of the present invention will be described below with reference to the accompanying drawings. Note that the present invention is not limited to the following embodiment, and various modifications are possible. In the following description, the greenhouse gas emission calculation system of the present invention may be referred to as the "system."

[0013] [Overall configuration] In Fig. 1 showing the overall configuration of the greenhouse gas emission calculation system, reference numeral 1 denotes a system main body, which is connected to a plurality of user terminals 100 via a communication network such as the Internet and is configured to be accessible from the user terminals 100. The system main body 1 includes emission calculation means 11 for calculating the amount of greenhouse gas emissions such as carbon dioxide, emission disclosure means 21 for disclosing the amount of greenhouse gas emissions calculated by the emission calculation means 11 to other users, emission comparison display means 31 for comparing and displaying the amount of greenhouse gas emissions calculated by the emission calculation means 11 with the amount of greenhouse gas emissions disclosed by other users, reduction plan proposing means 41 for proposing greenhouse gas emission reduction plans based on the amount of greenhouse gas emissions calculated by the emission calculation means 11, posted content publishing means 51 for publishing content posted by users, and response content publishing means 61 for publishing responses by other users to the posted content published by the posted content publishing means 51.

[0014] [Method of calculating emissions] As shown in FIG. 2, the emission calculation means 11 comprises a registered company data section 12, an emission intensity data section 13, a company activity amount section 14, a calculation section 15, and an output section 16.

[0015] [Registered Company Data Department] In the registered company data unit 12, during initial setup by the system administrator, company information is input and stored through the steps of accepting login S101, displaying a list of contracted companies S102, displaying a new registration screen S103, accepting input of company information S104, and storing company information S105, as shown in Fig. 3. When the system administrator edits company information, the company information is edited and stored through the steps of accepting login S101, displaying a list of contracted companies S102, accepting selection of the target company and displaying an editing screen S106, accepting edits of company information S107, and storing company information S105, as shown in Fig. 4.

[0016] Meanwhile, in the initial setup by the user (company implementing the system), as shown in Figure 5, company information is input and stored through the steps of accepting login S201, displaying company information S202, accepting input of company information S203, accepting input of reduction target S204, and storing company information S205. Here, in the step of accepting input of company information S203, information such as the number of employees, capital, industry, and business type is input as company information. In the step of accepting input of reduction target S204, the reduction target is set by setting a base year, a target year to be achieved, and numerical targets for the target reduction amount, such as "when is the base year," "by when," and "how much" to reduce.

[0017] [Emissions intensity data section] In the emission intensity data unit 13, as shown in Figure 6, the system administrator inputs and stores emission intensity data through the following steps: login acceptance S101, display of a list of emission intensity units for the target scope S108, acceptance of input file selection S109, reading of input file data and display of the results S110, acceptance of data editing and addition S111, acceptance of application start date setting S112, and storage of emission intensity data S113. The emission intensity data recorded in the input file can be sourced from an emission intensity database published by the Ministry of the Environment or other organizations, the Environmental Load Intensity Data Book based on Input-Output Tables (3EID), the inventory database IDEA, or the like. The data entered into the emission intensity data unit 13 is sorted into Scope 1, Scope 2, and Scope 3 by data type, and further classified into Categories 1 to 15 for storage.

[0018] As shown in Figure 7, the user, that is, the company that has introduced the system, can display the emission intensity data stored in the emission intensity data section 13 by following the steps of accepting login S201, displaying a list of emission intensity units for the target scope S206, and accepting the selection of the target emission intensity unit and displaying a detailed screen S207.

[0019] [Corporate Activity Department] In the corporate activity amount unit 14, when an input is made by a user (a company that has introduced the system), the activity amount is input and stored through the steps of accepting login S201, displaying an activity amount input screen S208, accepting input of activity amount data S209, and storing activity amount data S210, as shown in Fig. 8. In accepting input of activity amount data S209, the user can select to directly input data manually, input using OCR of a receipt, or read CSV data.

[0020] When manual direct data input is selected, as shown in FIG. 9, the activity amount is input through the steps of accepting addition of activity amount data S212, accepting selection of target year and month for activity amount data S213, obtaining a list of emission intensity units corresponding to the target year and month S214, displaying a list of "classifications" of emission intensity units and accepting selection of "classification" corresponding to the activity content S215, displaying a list of "items" belonging to the selected "classification" and accepting selection of "item" corresponding to the activity content S216, displaying "emission intensity units" belonging to the selected "item" and accepting selection of "emission intensity units" corresponding to the activity content S217, and accepting input of activity amount S218.

[0021] If receipt OCR input is selected, as shown in Figure 10, activity data is input through the following steps: (1) reading the receipt containing the activity data (S220), (2) saving the receipt image as an attachment (S221), (3) analyzing the reading results (S222), (4) accepting additional activity data and automatically inputting the target year / month, activity details, and activity data (S223), (5) obtaining a list of emission intensity units corresponding to the target year / month (S224), (6) displaying a list of emission intensity unit "classifications" and accepting the selection of a "classification" corresponding to the activity (S225), (7) displaying a list of "items" belonging to the selected "category" and accepting the selection of an "item" corresponding to the activity (S226), and (8) displaying the "emission intensity units" belonging to the selected "item" and accepting the selection of an "emission intensity unit" corresponding to the activity (S227). When using AI-OCR, the receipt image that is the basis for the activity data is scanned and uploaded. The AI ​​automatically recognizes the activity data from the uploaded receipt image and automatically sorts and enters it into each scope and category. The AI-OCR can be implemented using services such as Google's Vision API.

[0022] When reading CSV data is selected, as shown in Fig. 11, the activity amount is input through the steps of reading the CSV file containing the activity amount (S230), saving the CSV file as attached file data (S231), analyzing the reading results (S232), and accepting additional activity amount data and automatically inputting the target year and month, activity content, activity amount, and emission intensity (classification, item, emission coefficient) (S233).

[0023] [Calculation section] In the calculation unit 15, based on the data input in the corporate activity amount unit 14, as shown in FIG. 8, the carbon dioxide emission amount data is calculated and stored by steps S209 of calculating the emission amount and S211 of storing the carbon dioxide emission amount data.

[0024] When direct manual input of data is selected in the corporate activity amount section 14, the carbon dioxide emission amount is calculated in the step of calculating carbon dioxide emission amount S219, as shown in FIG.

[0025] When input of receipts using OCR is selected in the corporate activity amount section 14, the carbon dioxide emissions are calculated by steps S228, S229, as shown in FIG. 10, and S229, where the carbon dioxide emissions data of the attached file are registered as an attached file.

[0026] When reading of CSV data is selected in the corporate activity amount section 14, the carbon dioxide emission amount is calculated by steps S234, S235 of registering the carbon dioxide emission data of the attached file as an attached file, as shown in FIG. 11.

[0027] The carbon dioxide emissions are calculated by multiplying each corporate activity amount by the corresponding emission intensity (emission coefficient). That is, calculation unit 15 calls up the activity amount stored in corporate activity amount unit 14 and the corresponding emission intensity data, and multiplies both of the called data.

[0028] [Output section] In the output unit 16, when operated by the user, i.e., the company that has introduced the system, a dashboard is output as the calculation results of the carbon dioxide emissions through the steps of accepting login S201, obtaining activity data and emissions data for the target period and calculating the total emissions S236, and displaying graphs and lists of total emissions for each scope and category S237, as shown in FIG. 12.

[0029] Alternatively, as shown in FIG. 13, detailed information on the total emissions is output as the calculation result of the carbon dioxide emissions through the steps of accepting login S201, acquiring activity data and emissions data for the target period and calculating the total emissions S236, and displaying a graph and list of the total emissions S238.

[0030] Furthermore, as shown in FIG. 14, detailed information for each scope and category is output as the calculation results of carbon dioxide emissions through the steps of accepting login S201, acquiring activity data and emission data for the scope and category to be displayed within the target period and calculating the total emission amount S239, and displaying a graph and list of the scope and category to be displayed S240.

[0031] The information on the calculation results that is output is processed into tables, graphs, etc. based on the carbon dioxide emission data calculated and stored by the calculation unit 15. For example, the transition of emissions and the deviation from the target set at the beginning of system introduction may be output as a graph on a monthly basis.

[0032] [Emissions disclosure method] In the emission disclosure means 21, when operated by the user, i.e., the company that has introduced the system, the greenhouse gas emissions calculated by the emission calculation means 11 are made public to other users through the steps of accepting login S201, accepting permission to disclose to other companies S241, and enabling a comparison display mode with companies that have permitted disclosure in the output section S242, as shown in Figure 15.

[0033] Furthermore, if the disclosure of greenhouse gas emissions calculated by the emission calculation means 11 is permitted by the emission disclosure means 21, the following will be made public: the company name and link to its homepage, the reduction target figure, the base year for reduction, the emissions in the base year for reduction, the breakdown of emissions in the base year for reduction (electricity %; gas %; gasoline %; etc.), the current emissions, the current breakdown of emissions, the current emission reduction rate compared to the base year, what is being done for reduction, and whether or not the company has been certified by a public institution such as SBT.

[0034] [Emission comparison display means] In the emission comparison display means 31, when operated by a user (a company that has introduced the system), as shown in FIG. 16, the greenhouse gas emissions calculated by the emission calculation means 11 are compared and displayed with the greenhouse gas emissions made public by other users through the steps of accepting login S201, displaying the output section S243, accepting switching to a comparison display mode with companies permitted to be disclosed S244, accepting selection of a company to be compared S245, obtaining emission information of the company to be compared that corresponds to the currently displayed content S246, and displaying a comparison with emissions of a benchmark company S247.

[0035] Here, instead of disclosing the reduction status of the company that has introduced the system within the system and sharing it with other companies, it is possible to check the reduction status of other companies. In other words, only when the company's emission information is permitted to be disclosed to other companies in the emission disclosure means 21, the emission information of other companies is displayed by the emission comparison display means 31.

[0036] [Means for proposing reduction plans] As shown in FIG. 17, the reduction plan proposing means 41 comprises a reduction plan input unit 42, a reduction plan selection unit 43, and a reduction plan output unit 44.

[0037] [Reduction proposal input section] In the reduction plan input unit 42, when operated by a system administrator, as shown in FIG. 18, the input reduction plans are classified by scale and means and stored in the system through the following steps: accepting login S101, displaying a list of carbon dioxide reduction plans S114, displaying a new reduction plan registration screen and accepting input of the reduction plan S115, accepting input of the scale and means targeted by the reduction plan S116, and storing the reduction plan S117.

[0038] [Reduction Plan Selection Department] 19, in steps S118 for selecting a target company and S119 for selecting candidate reduction plans of an appropriate classification based on the target company's company information and emissions calculation results, the reduction plan selection unit 43 refers to the company information input and stored from the registered company data unit 12 when the system was first introduced and the emissions calculation results calculated and stored by the calculation unit 15, and selects reduction plans of an appropriate classification based on the data of the user company that has introduced the system from among the reduction plans input and stored from the reduction plan input unit 42. This process is automatically executed periodically by the system.

[0039] [Reduction plan output section] In the reduction plan output unit 44, when operated by the user (the company that has introduced the system), an outline and detailed data of the reduction plans selected by the reduction plan selection unit 43 are output through the steps of accepting login S201, accepting display of a screen of the proposed reduction plans S248, and accepting display of the details of the proposals S249, as shown in Fig. 20. In addition, if necessary, it is possible to make an inquiry to the system administrator through the system through the step of accepting inquiry to the system administrator S250.

[0040] [Method of publishing post content] In the posted content publishing means 51, when operated by the user (system introducing company), the posted content posted by the user is published through the steps of accepting login S201, displaying the communication space S251, displaying a new registration form S252, accepting and registering input of the posted content S253, and publishing the posted content S254, as shown in Fig. 21. Here, in displaying the communication space S251, a list of posted content posted in the past is displayed as a list of "problems," and in publishing the posted content S254, the currently posted content is newly published as a "problem." The posted content is published anonymously.

[0041] [Answer content disclosure method] In the answer content publishing means 61, when operated by the system introducing company (user), the answer content provided by other users to the "problem" posted by the posted content publishing means 51 is published through the steps of accepting login S201, displaying the communication space S251, accepting selection of an item from the list of posted content S255, accepting and registering the answer content S256, and publishing the answer content S257, as shown in Fig. 22. The answer content is published anonymously.

[0042] [Anonymous communication space] The posting content publishing means 51 and response content publishing means 61 create an anonymous communication space that can only be used by users, i.e., companies that have adopted the system, and this allows users to interact with each other and solve their concerns about reducing carbon dioxide emissions. In addition, the posting content and response content can be viewed by any user, so users with similar concerns can refer to them and solve their problems. In particular, small and medium-sized enterprises have had the problem of having no one to consult with because they only have one person in the company in charge of reducing carbon dioxide emissions, and therefore being unable to solve their concerns; however, this problem can be solved by using the communication space. This is also expected to promote collaboration between companies towards decarbonization.

[0043] As described above, the greenhouse gas emission calculation system of this embodiment comprises emission calculation means 11 that calculates greenhouse gas emissions, emission disclosure means 21 that discloses the greenhouse gas emissions calculated by said emission calculation means 11 to other users, and emission comparison display means 31 that compares and displays the greenhouse gas emissions calculated by said emission calculation means 11 with the greenhouse gas emissions disclosed by other users. By calculating greenhouse gas emissions and comparing and displaying them with the greenhouse gas emissions disclosed by other users, the system makes it possible to easily calculate greenhouse gas emissions and also supports and promotes decarbonization efforts by encouraging competition among users to decarbonize.

[0044] In addition, the system is provided with a reduction plan proposal means 41 that proposes greenhouse gas emission reduction plans based on the greenhouse gas emissions calculated by the emission calculation means 11, and by proposing greenhouse gas emission reduction plans based on the greenhouse gas emissions, it is possible to promote efforts toward decarbonization.

[0045] Furthermore, the system is provided with a posting content publishing means 51 that publishes the content posted by users, and a response content publishing means 61 that publishes the responses of other users to the content posted by the posting content publishing means 51, and by publishing the content posted by users and the responses of other users, it is possible to support efforts towards decarbonization.
