Description

[Technical Field]

[0001] The present invention relates to a method for managing greenhouse gas emissions. [Background technology]

[0002] With regard to greenhouse gas emissions from businesses resulting from the use of fuel, electricity, etc., reporting systems targeting SCOPE 1 emissions (direct emissions by the company) and SCOPE 2 emissions (indirect emissions by the company) have become widespread, and efforts to calculate and reduce emissions in SCOPE 1 and SCOPE 2 have progressed.

[0003] Non-Patent Document 1 proposes that, with the aim of further reducing greenhouse gas emissions by businesses, SCOPE 3 emissions should be calculated as emissions other than SCOPE 1 and SCOPE 2, i.e., emissions from the supply chain of other related businesses (the entire series of processes including raw material procurement, manufacturing, logistics, sales, and disposal).

[0005] However, although the technology disclosed in Non-Patent Document 1 discloses methods for calculating greenhouse gas emissions related to SCOPE 3, it takes a great deal of time and effort for each business, particularly companies and local governments, to collect and input a huge amount of data to calculate emissions, calculate emissions, and manage the calculation results.In particular, in the area of ​​GHG emissions management, the scope of emissions to be calculated is expanding, the data that forms the basis for emissions calculations varies widely for each scope, and data management methods differ for each business, so improvements in business efficiency through the introduction of advanced technology are lagging behind.

[0006] Therefore, the present invention aims to provide a method for efficiently managing GHG emissions by utilizing advanced technology in the area of ​​GHG emissions management, such as the calculation of greenhouse gas emissions by businesses. [Means for solving the problem]

[0010] The contents of an embodiment of the present invention will be listed and explained below. A greenhouse gas emission management system (hereinafter simply referred to as "system") according to an embodiment of the present invention has the following configuration. [Item 1] A method for managing greenhouse gas emissions by a business, comprising: The control unit of the management terminal is A request to create a template consisting of multiple input items for calculating greenhouse gas emissions is received from the business operator's terminal, Refer to the input data for calculating the company's past greenhouse gas emissions, In the template, input items are created based on the past input data; A method in which, when the business operator accepts data input for the input items, information to assist the data input is displayed on the business operator terminal based on past input data of the business operator.

The method according to item 1, wherein input data for calculating greenhouse gas emissions of a business operator other than the business operator is referenced.

[0011] First Embodiment Hereinafter, a system according to an embodiment of the present invention will be described with reference to the drawings.

[0012] FIG. 1 is a diagram illustrating a greenhouse gas emission management system according to a first embodiment of the present invention.

[0013] As shown in FIG. 1, in an emission amount management system 1 according to this embodiment, an administrator terminal 100 and a plurality of business operator terminals 200A and 200B are connected to each other via a communication network NW.

[0014] For example, the management terminal 100 receives basic information about the business and input information (eg, image data of bill information) for calculating greenhouse gas (eg, CO2) emissions from the business terminals 200A and 200B.

[0015] The management terminal 100 also analyzes the received image data of the invoice information using machine learning, extracts necessary items of the invoice information contained in the image data, and calculates the greenhouse gas emissions. The management terminal 100 also analyzes the calculated changes in greenhouse gas emissions over time (e.g., increases or decreases) using machine learning, and predicts the causes of the changes.

[0016] Furthermore, the management terminal 100 has a wallet and is connected to the public blockchain network NW. Based on the information on greenhouse gas emissions for each predetermined period, the management terminal 100 generates a single hash value using SHA256 or another hash function and records it as transaction information on the blockchain network. On the blockchain network, a block is generated based on the transaction information, the hash value recorded in the previous block, and a nonce value mined by the node. This block is recorded after the previous block, forming a blockchain. The hash generation and / or recording of transaction information on the blockchain can also be performed via another terminal rather than the management terminal 100. In this case, the management terminal 100 transmits the greenhouse gas emissions calculated in the matching process to the other terminal. Furthermore, the management terminal 100 can record information on greenhouse gas emissions as a smart contract on the blockchain network. Using a smart contract, contracts for emissions trading with other businesses can be automatically generated, approved, and executed based on the emissions information without the involvement of a third party. Furthermore, the smart contract allows each business operator to refer to transaction information without going through the management terminal, improving service convenience and reducing operational costs. Furthermore, the management terminal 100 is connected to a large-scale language model (LLM, e.g., GPT) 300 via the network, which accepts predetermined questions from other terminals via an API (Application Programming Interface), analyzes the questions, and generates answers.

[0017] As described above, a public blockchain allows transactions to be approved by an unspecified number of nodes and miners, rather than by a specific administrator, and therefore can ensure higher data tamper resistance and fault tolerance than a private blockchain, thereby ensuring the security of transactions. Therefore, a public blockchain is preferable as the destination for recording energy transactions in this embodiment. Typical public blockchains include Bitcoin and Ethereum, and Ethereum, for example, has higher tamper resistance and reliability than other public blockchains.

[0018] Furthermore, the management terminal 100 can associate information regarding greenhouse gas emissions using an identifier or the like and record it on the blockchain network as a non-fungible token (hereinafter, "NFT"). NFTs are tokens issued, for example, in the "ERC721" standard of Etherium, a blockchain network platform, and are a unit of data recorded on the blockchain network, and are non-fungible in nature. NFTs are recorded on the blockchain together with smart contracts and are traceable, making it possible to prove transaction information, including details and history of business operators managing greenhouse gas emissions.

[0019] FIG. 2 is a functional block diagram of a management terminal that constitutes the emission management system.

[0020] The communication unit 110 is a communication interface for communicating with an external terminal via a network NW, and communication is performed according to a communication protocol such as TCP / IP (Transmission Control Protocol / Internet Protocol).

[0021] The storage unit 120 stores input data, programs for executing various control processes and functions in the control unit 130, and is composed of RAM (Random Access Memory), ROM (Read Only Memory), and the like. The storage unit 120 also has an operator data storage unit 121 that stores various data related to operators, and an AI model storage unit 122 that stores learning data and learning models obtained by AI (artificial intelligence) learning the learning data. A database (not shown) that stores various data may be constructed outside the storage unit 120 or the management terminal 100.

[0022] The control unit 130 controls the overall operation of the management terminal 100 by executing programs stored in the storage unit 120, and is composed of a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), etc. The functions of the control unit 130 include an information receiving unit 131 that receives information from an external terminal such as the business operator terminal 200, an image analysis unit 132 that analyzes image data such as invoice information received from the business operator terminal and calculates greenhouse gas emissions, a cause analysis unit 133 that analyzes the image data and analyzes the cause of time-series changes in the greenhouse gas emissions calculated based on information included in the extracted invoice information, a transaction processing unit 134 that compiles information on greenhouse gas emissions for a predetermined period, generates a hash value, and records the hash value as transaction information on the blockchain network, and a report generation unit 135 that generates and transmits report data to the business operator every predetermined period to output the results of an analysis of greenhouse gas emissions and the cause of changes in emissions.

[0023] Although not shown, the control unit 130 also has an image generation unit that generates screen information to be displayed via a user interface of an external terminal such as the business operator terminal 200. For example, the control unit 130 generates information to be displayed on the user interface by using image and text data stored in the storage unit 120 as material and arranging various images and text in predetermined areas of the user interface based on predetermined layout rules. Processing related to the image generation unit can also be executed by a GPU (Graphics Processing Unit).

[0024] The management terminal 100 also has a wallet (not shown) necessary for recording transaction information in the blockchain network. Note that this wallet may also be located outside the management terminal 100.

[0025] FIG. 3 is a functional block diagram of the business operator terminal that constitutes the emission management system.

[0026] The operator terminal 200 includes a communication unit 210 , a display operation unit 220 , a storage unit 230 , and a control unit 240 .

[0027] The communication unit 210 is a communication interface for communicating with the management terminal 100 via the network NW, and communication is carried out according to a communication protocol such as TCP / IP.

[0028] The display operation unit 220 is a user interface used by the business operator to input instructions and display text, images, etc. in accordance with input data from the control unit 240, and is configured with a display, keyboard, and mouse when the business operator terminal 200 is configured as a personal computer, and is configured with a touch panel, etc. when the business operator terminal 200 is configured as a smartphone or tablet terminal. This display operation unit 220 is started up by a control program stored in the storage unit 230 and executed by the business operator terminal 200, which is a computer (electronic calculator).

[0029] The storage unit 230 stores input data, programs for executing various control processes and functions within the control unit 240, and is composed of RAM, ROM, etc. The storage unit 230 also temporarily stores the contents of communications with the management terminal 100.

[0030] The control unit 240 controls the overall operation of the operator terminal 200 by executing the programs stored in the storage unit 230, and is configured from a CPU, a GPU, and the like.

[0031] FIG. 4 is a diagram illustrating details of business operator data according to the first embodiment of the present invention.

[0032] The business operator data 1000 shown in FIG. 4 stores various data related to the business operator acquired from the business operator via the business operator terminal 200. For ease of explanation, FIG. 4 shows an example of one business operator (a business operator identified by business operator ID "10001"), but information on multiple businesses can be stored. The various data related to the business operator can include, for example, basic information about the business operator (e.g., the business operator's corporate name, user name, address, industry, contact information, email address, business name, affiliated company name, and business operator names related in the supply chain), input information (e.g., image data of invoice information), analysis information (e.g., information regarding invoices extracted from image data, greenhouse gas emissions, and predicted causes of changes in greenhouse gas emissions), customer information (e.g., customer ID, blockchain address, and the like), and offset report information (e.g., TXID, NFTID, and the like).

[0033] FIG. 8 is a flowchart showing an example of the process of calculating greenhouse gas emissions according to the first embodiment of the present invention.

[0034] First, in the process of step S101, the information acquisition unit 131 of the control unit 130 of the management terminal 100 acquires image data including invoice information collected by the business operator from the business operator terminal 200 via the network NW. The business operator uploads invoices, receipts, slips, etc. (in this embodiment, these are collectively referred to as "invoices") to the management terminal 100 via the business operator terminal 200 in file formats such as PDF, Excel, JPG, etc. (in this embodiment, these are collectively referred to as "image data"). The image data acquired by the information acquisition unit 131 is stored as input information in the business operator data storage unit 121 of the memory unit 120.

[0035] Next, in step S102, the image analysis unit 132 of the control unit 130 of the management terminal 100 analyzes the image data acquired in the previous step using machine learning. Here, the image analysis uses a technique known as OCR, and the image analysis unit 132 of the control unit 130 of the management terminal 100 recognizes text from the image data using a learning model that has been generated in advance by learning from image data of multiple invoices in various formats and that is stored in the AI ​​model storage unit 122 of the memory unit 120, and extracts items contained in the invoice information as structured character string data. Here, the image analysis can also use an image analysis engine (such as an OCR engine) provided by a business operator other than the management terminal 100, which is linked via an API.

[0036] Image analysis is performed by recognizing and extracting text from image data containing invoice information, as shown in FIG. 5. As shown in FIG. 5, invoice information includes various items, such as the electricity bill breakdown, the amount (yen) for each breakdown, the contracted power (kW), the amount of electricity used (kWh) for each breakdown, the total amount (yen), and the date (year and month). While this example illustrates an electricity bill breakdown, it may also be an invoice for other energy usage, including electricity, gas, and fuel. It may also be a receipt for travel expenses, a receipt for employee commuting expenses, an invoice for a transaction with a freight company, or a breakdown of an invoice for a transaction with a waste disposal company. The image analysis unit 132 analyzes the image data of this invoice information to extract, as text, the amount information, activity level information, and other information contained in the invoice information. The extracted invoice information is stored as analysis information in the business operator data storage unit 121 of the memory unit 120. In this way, image analysis using machine learning allows businesses to acquire the vast amount of information necessary for calculating greenhouse gas emissions as image data without manually inputting invoice information. Furthermore, highly accurate image recognition allows for accurate extraction of the information necessary for calculating greenhouse gas emissions, thereby achieving more efficient and accurate greenhouse gas emission calculations. Image analysis techniques include methods for understanding the format of an invoice based on angle correction, approximation of a design, and feature points (e.g., size ratios relative to a logo, circular notation, distance specification from text such as kiloliters) contained in the image data, and extracting the items and amounts contained in the invoice as structured data. Furthermore, the management terminal 100 can send an instruction to the LLM 300 to calculate energy usage using invoice information as input data, causing the LLM 300 to calculate energy usage. More specifically, the LLM300 can calculate energy usage by searching for vector values ​​that approximate vector values ​​converted from character information (text information) contained in the input data, and predicting information about business partners and / or energy usage (energy usage fees such as gasoline costs and electricity charges) contained in the invoice information.In this case, the instruction (prompt) sent to the LLM 300 can include text such as "Please provide what appears to be the charge (of the invoice)" or "Please answer what appears to be the business partner (of the invoice)." For example, when the LLM 300 returns an answer with multiple possible fee information items, the management terminal 100 can reference the business operator's past invoice information stored as business operator data 1000 in the storage unit 120 as a data set, and can set an instruction (prompt) to predict and extract energy usage based on information about energy usage (e.g., the charge listed in the first item on the invoice is the charge related to energy usage) included in the invoice information registered as master, and send the instruction (prompt) from the management terminal 100 to the LLM 300, thereby obtaining a regenerated answer. The management terminal 100 can also generate an instruction to reference the business operator's past invoice information in advance and send it to the LLM 300.

[0037] Next, in step S103, the image analysis unit 132 of the control unit 130 calculates greenhouse gas emissions based on the invoice information extracted from the image data or based on information on energy usage obtained from the LLM 300. Here, greenhouse gas emissions are classified into SCOPE 1, SCOPE 2, and SCOPE 3, with SCOPE 1 being direct greenhouse gas emissions by the business itself (e.g., emissions associated with fuel combustion and industrial processes), SCOPE 2 being indirect emissions associated with the use of electricity, heat, gas, etc. supplied to the business by other companies, and SCOPE 3 being the calculation standard for emissions throughout an organization's supply chain issued by the GHG Protocol, and referring to emissions throughout a business's supply chain (the entire series of processes, including raw material procurement, manufacturing, logistics, sales, and disposal). SCOPE 3 is further classified into 15 categories (1) purchased products / services, 2) capital goods, 3) fuel and energy-related activities not included in SCOPE 1 and SCOPE 2, 4) transportation and distribution (upstream), 5) waste generated from operations, 6) business travel, 7) employee commuting, 8) leased assets (upstream), 9) transportation and distribution (downstream), 10) processing of sold products, 11) use of sold products, 12) disposal of sold products, 13) leased assets (downstream), 14) franchises, and 15) investments. Here, greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3), but this embodiment will be described using CO2 as an example.

[0038] Greenhouse gas emissions are calculated by defining a business's electricity consumption, cargo transport volume, waste disposal volume, and various transaction amounts as activity volume, and multiplying this activity volume by the CO2 emissions per kWh of electricity used, CO2 emissions per ton of cargo transported, and CO2 emissions per ton of waste incinerated as emissions intensity. Greenhouse gas emissions are calculated for the above-mentioned SCOPE 1, SCOPE 2, and SCOPE 3 (SCOPE 3 is divided into 15 categories), and the total emissions are calculated as supply chain emissions.

[0039] In this embodiment, the image analysis unit 132 extracts related invoice information by SCOPE 1, SCOPE 2, and SCOPE 3 (and further by category for SCOPE 3), and calculates emissions based on the invoice information, for example, the amount of electricity used (kWh), using the above calculation method. The calculated emissions are stored as analysis information in the business operator data storage unit 121 of the memory unit 120.

[0040] Next, in the processing of step S104, the report generation unit 135 of the control unit 130 generates a visualized report showing a breakdown of emissions over time by SCOPE (and further by category for SCOPE 3) based on the information about the calculated emissions.

[0041] FIG. 9 is a flowchart showing an example of the process of predicting the causes of changes in greenhouse gas emissions according to the first embodiment of the present invention.

[0042] First, in the process of step S201, the cause analysis unit 133 of the control unit 130 of the management terminal 100 refers to information about the greenhouse gas emissions of the business operator calculated in step S103 of FIG. 8. Here, for the greenhouse gas emissions, the emissions by SCOPE (and further by category for SCOPE 3) are referenced. Furthermore, the cause analysis unit 133 can check changes (increases or decreases) in the greenhouse gas emissions by referring to the past emission data of the same business operator. As described above, the emissions are stored as analysis information in the business operator data storage unit 121 of the memory unit 120.

[0043] Next, in the processing of step S202, the cause analysis unit 133 analyzes and predicts the cause of changes in emission amounts by machine learning based on the emission amount information referenced above. Here, when analyzing the cause, the cause analysis unit 133 of the control unit 130 of the management terminal 100 predicts the cause of changes in emission amounts by SCOPE (and further by category for SCOPE 3) by using the emission amount information referenced above, factors that affect changes (increases or decreases) in emission amounts, and a learning model that has been generated in advance by learning data related to factors that affect changes (increases or decreases) in emission amounts that is stored in the AI ​​model storage unit 122 of the memory unit 120.

[0044] Factors that affect changes (increases or decreases) in output include, for example, weather, temperature, product demand and / or factory operation, store or factory business hours, equipment or facility changes, software measures, energy-saving activities, fuel conversions, energy menu changes, changes in business trips or commuting, and the amount of electricity generated by privately-owned power plants. Each of these factors affects emissions in one of the following scopes. For example, weather affects precipitation, wind volume, hours of sunshine, and temperature. Precipitation affects the amount of hydroelectric power generation, wind volume affects the amount of wind power generation, hours of sunshine affect the amount of solar power generation, and temperature affects air conditioning. Furthermore, the amount of electricity generated affects the amount of privately-owned power generation, which affects CO2 emissions from electricity, thereby affecting emissions in SCOPE 2. Meanwhile, air conditioning affects gas usage, which affects CO2 emissions from gas combustion, thereby affecting emissions in SCOPE 1. Energy-saving activities, factory operation due to product demand, and business hours affect electricity usage, which in turn affects SCOPE 2. In addition, EMS, replacement of refrigeration equipment, introduction of energy-saving equipment, and automobile usage also affect electricity usage and thus affect SCOPE 2. In addition, automobile usage, fuel efficiency, boiler usage, and boiler efficiency affect fuel usage, which affects CO2 emissions from fuel, thereby affecting SCOPE 1.

[0045] In addition, the factor of product sales volume affects categories 1, 9, 10, 11, and 12 in SCOPE 3, capital investment affects category 2, renewable energy ratio and amount of energy procured affects category 3, number of transports and changes in transport routes affects categories 4 and 9, product loss rate affects category 5, business trips and number of people commuting to the office affects category 6, number of people commuting to the office and number of employees commuting to the office affects category 7, electricity consumption affects category 8, reduction in processing through product improvements affects category 10, improvements to energy-efficient products affects category 11, increased recycling rate affects category 12, electricity used in tenant offices affects category 13, franchise emissions affects category 14, and emissions from investment targets affects category 15.

[0046] In this way, by using machine learning to learn which factors affect which scope or category, and then obtaining information on emissions and information on each factor from businesses, it is possible to predict the causes of changes in emissions. Here, by predicting the causes of emissions using machine learning, it is possible to efficiently and accurately predict the factors that affect changes in greenhouse gas emissions for each business and for each scope.

[0047] Next, in the processing of step S203, the report generation unit 135 of the control unit 130 generates a visualized report on the causes of changes in emissions by SCOPE (and further by category for SCOPE 3) based on the information regarding the predicted causes of changes in emissions analyzed above.

[0048] FIG. 10 is a flowchart showing an example of a transaction process of greenhouse gas emissions according to the first embodiment of the present invention.

[0049] First, in the process of step S301, the transaction processing unit 134 of the control unit 130 of the management terminal 100 refers to the business operator data stored in the business operator data storage unit 121 of the memory unit 120. Here, the business operator data to be referred to includes business operator analysis information (emissions of greenhouse gases for each SCOPE), etc.

[0050] Next, in step S302, the transaction processing unit 134 generates a hash value based on the business data referenced in step S301. That is, the transaction processing unit 134 generates a row of hash values ​​for greenhouse gas emissions over a predetermined period using a hash function and records the hash value as transaction information in the public blockchain. On the blockchain network, this block is generated based on the transaction information, the hash value recorded in the previous block, and the nonce value mined by the node, and is recorded following the previous block, forming a blockchain. Here, in this example, to reduce the cost of blockchain recording, it is assumed that the block is recorded in layer 2 (e.g., a side chain) different from the main blockchain (so-called layer 1).

[0051] Furthermore, the transaction processing unit 134 can assign and manage NFTIDs by linking them to the blockchain records of the greenhouse gas emissions of the business. More specifically, as shown in Fig. 4, the business's customer ID can be assigned as customer information to the business data 1000, the blockchain address to be referenced can be stored, and the NFTID and TXID can be assigned as offset report information.

[0052] As shown in Figure 6, each NFT ID is associated with a blockchain address on the blockchain network, and the management terminal 100 manages NFT IDs and customer IDs. For example, information about greenhouse gas emissions for a business associated with customer ID "2" can be retrieved by referencing the blockchain address for each NFT ID, such as NFT IDs "13" and "14," as shown in Figure 7. Figure 7 shows information about an offset report associated with NFT ID "14." A TXID is assigned to the offset report, and the offset report includes information about CO2 emissions by scope, the target year and month, and the report's publication date. In addition to the CO2 emissions for the target year and month in this example, recent CO2 emissions, reduced CO2 emissions, and offset CO2 emissions can also be converted into NFTs. By managing CO2 emissions in this way, businesses can trade NFT-converted certificates while ensuring tamper-resistance and transaction reliability, and can also verify emissions to third parties.

[0053] FIG. 11 is a flowchart illustrating an example of a template registration method according to a second embodiment of the present invention. Conventionally, the management terminal 100 provides a business operator with a function for formatting the locations where data is registered for calculating greenhouse gas emissions on a fixed basis and the data entry items, and saving the formatted data as templates in the system on a regular basis, such as monthly. When registering a template, the business operator must manually register the location and emission intensity data, which requires manual organization by location where fixed amounts are generated and by data, imposing a burden on the business operator. Therefore, this embodiment aims to identify the locations where data entry is performed on a fixed amount and the input data items, and to make an initial template proposal as part of a business operator's greenhouse gas emissions management method. A detailed description is provided below.

[0054] In the process of step S401, the information acquisition unit 131 of the control unit 130 of the management terminal 100 receives a request from the business operator terminal 200 to create a template for calculating greenhouse gas emissions. Here, the template is configured to include multiple input items, and includes items for inputting data such as base information, classification, item, and emission intensity. The business operator sends an instruction to the management terminal 100 to create template input via a chat communication interface with an AI chatbot or the like that is displayed by a pop-up or the like on the business operator terminal 200, or by selecting (clicking, tapping, etc.) the "AI Recommendation" button displayed on the business operator terminal 200.

[0055] Next, in step S402, the report generation unit 135 of the control unit 130 of the management terminal 100 references the past input data for calculating greenhouse gas emissions of the business that requested template creation. The business previously input data, such as industry, business location name, department name, and activity data (classification, item, and emission intensity) for calculating greenhouse gas emissions at each of its multiple locations. The management terminal 100 stores the previously input data in the business location data storage unit 121 of the memory unit 120. The report generation unit 135 then references the business's past input data stored above, identifies frequently registered locations and their activity data (classification / item / emission intensity), and determines these as items to be included in the template. Alternatively, the report generation unit 135 can extract items reported in ESG data books or other publications of businesses in the same industry but different from the business, based on a learning model previously stored in the AI ​​model storage unit 122 of the memory unit 120, which the report generation unit 135 has acquired by crawling websites and machine-learned, and determine these as items to be included in the template.

[0056] Next, in the process of step S403, the report generation unit 135 generates a template configured to include the determined input items, and displays the generated template on the business operator terminal 200. Here, the report generation unit 135 displays check boxes near the input items in the generated linked plate, and the business operator's representative can confirm the necessary bases and items by checking the check boxes displayed on the business operator terminal 200. Upon receiving confirmation input from the business operator terminal 200, the report generation unit 135 registers the final template by storing it in the business operator data storage unit 121 of the memory unit 120.

[0057] In this way, based on the template, businesses can efficiently input data for calculating greenhouse gas emissions, thereby reducing the burden of managing greenhouse gas emissions on the businesses.

[0058] FIG. 10 is a flowchart illustrating an example of a template input reception method according to a second embodiment of the present invention.

[0059] Once the initial registration of the template is complete, the business operator will enter data into given input items based on the template at predetermined intervals (e.g., monthly) from the next time onwards in order to calculate greenhouse gas emissions. First, in step S501, the information acquisition unit 131 of the control unit 130 of the management terminal 100 accepts data input for calculating greenhouse gas emissions from the business operator terminal 200. Here, there is a possibility that the business operator's personnel may make data entry omissions or errors. For example, there may be a discrepancy between the input data from last month and the input data from this month, or data similar to last month's data may be entered without understanding differences in seasonal trends, or activity data from multiple locations may be entered for activity data from one location.

[0060] Therefore, in the process of step S502, the report generation unit 135 of the control unit 130 refers to past registration data entered by the business in the business data 1000 in the storage unit 120. Examples of such data include activity data of the business, such as invoices for the same month or quarter of last year, activity data for the previous month, and activity data for the same business location. Alternatively, the report generation unit 135 can use the business's past registered activity data stored in the AI ​​model storage unit 122 of the storage unit 120 as input information, perform machine learning to predict current activity data, and refer to the generated learning model.

[0061] Next, based on the processing of step S503, the report generation unit 135 outputs information to assist the business operator in entering data near the input field when the business operator enters data on the template input screen displayed on the business operator terminal 200 or when the business operator has entered data. Examples of the information to be output to assist the business operator include the business operator's past registration data, specifically, the business operator's registration (activity) data for the same month (same quarter) of last year, the business operator's registration (activity) data for last month, and supplementary information that takes into account similar coefficients (registration trends for each company's locations, products or other activities with the same proportionality), etc. Furthermore, based on a learning model, it is also possible to display an estimated value that takes into account the growth trend of the same month from the input data for the month before and after last year. In this way, this example prevents business operators from making omissions or errors when entering data into the template, thereby improving the efficiency of data entry for calculating greenhouse gas emissions.

[0062] The above-described embodiment is merely an example for facilitating understanding of the present invention, and is not intended to limit the present invention. The present invention can be modified and improved without departing from the spirit thereof, and it goes without saying that the present invention includes equivalents thereof.
