Summary of the Invention

Problems to be Solved by the Invention

[0005] However, while the technology disclosed in Non-Patent Document 1 provides information on methods for calculating greenhouse gas emissions related to SCOPE 3, businesses, especially corporations and local governments, spend a great deal of time and effort collecting and inputting vast amounts of data for emission calculations, calculating emissions, and managing the calculation results. In particular, in the field of GHG emission management, the scope of emissions subject to calculation is expanding, the data that forms the basis for emission calculations varies widely for each SCOPE, and data management methods differ from business to business, all of which have hindered the improvement of operational efficiency through the introduction of advanced technologies.

[0006] Therefore, the present invention aims to provide a method for efficiently managing greenhouse gas emissions by reducing the workload involved in the calculation of greenhouse gas emissions by businesses, in the field of GHG emission management. [Means for solving the problem]

[0010] The embodiments of the present invention will be described below. The greenhouse gas emission management system according to the embodiments of the present invention (hereinafter simply referred to as the "system") has the following configuration. [Item 1] A method for managing a business operator's greenhouse gas emissions, which is performed by a management terminal, The control unit of the aforementioned management terminal is: The aforementioned business operator receives response data from its terminal to questions prepared by an organization that discloses greenhouse gas emissions. Referencing the data on the greenhouse gas emissions of the business operator stored in the memory unit of the management terminal, A method for detecting contradictions in the answer content of the answer data. [Item 2] The method according to Item 1, wherein the data on the greenhouse gas emissions includes information on the reduction target of the greenhouse gas emissions of the operator.

[Item 5] The method according to Item 1, wherein the control unit transmits an improvement plan for improving the score based on the answer data to the operator terminal.

[0011] <The 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 for explaining a greenhouse gas emissions management system according to the first embodiment of the present invention.

[0013] As shown in FIG. 1, in the emissions management system 1 in the present embodiment, the administrator terminal 100 and a plurality of operator terminals 200A and 200B are interconnected via a communication network NW.

[0014] <0​​​​​

[0016] Furthermore, the management terminal 100 has a wallet and connects to the public blockchain network NW. Based on the greenhouse gas emission information for each predetermined period, the management terminal 100 generates a single hash value using SHA256 or another hash function and records it on the blockchain network as transaction information. On the blockchain network, a 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, thus forming the blockchain. Here, the hash generation and / or recording of transaction information to the blockchain can also be performed via another terminal instead of the management terminal 100. In this case, the management terminal 100 transmits the greenhouse gas emission calculated in the matching process to the other terminal. Furthermore, the management terminal 100 can record the greenhouse gas emission information as a smart contract on the blockchain network. By using smart contracts, based on the emission information, contracts regarding emission trading with other businesses can be automatically generated, approved, and executed without the need for a third party. Furthermore, smart contracts enable each service provider to access transaction information without needing to use a management terminal, thereby improving service convenience and reducing operational costs.

[0017] Here, as mentioned above, in a public blockchain, transaction approval is performed not by a specific administrator but by an unspecified number of nodes and miners. Therefore, compared to a private blockchain, it can guarantee higher data immutability and fault tolerance, thus ensuring the security of transactions. For this reason, in this embodiment, a public blockchain is preferable as the destination for recording electricity transactions. Representative public blockchains include Bitcoin and Ethereum, but Ethereum, for example, has higher immutability and reliability among public blockchains.

[0018] Furthermore, the management terminal 100 can associate information regarding greenhouse gas emissions with identifiers and record it on the blockchain network as a Non-Fungible Token (NFT). An NFT is, for example, a token issued under the "ERC721" standard of Ethereum, a blockchain network platform, and is a unit of data recorded on the blockchain network, possessing the characteristic of being non-fungible. Since NFTs are recorded on the blockchain along with smart contracts and are traceable, they can prove transaction information including details and history of business information that manages greenhouse gas emissions.

[0019] Figure 2 is a functional block diagram of the management terminals that make up the emissions management system.

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

[0021] The memory unit 120 stores programs for executing various control processes and functions within the control unit 130, input data, etc., and is composed of RAM (Random Access Memory), ROM (Read Only Memory), etc. The memory unit 120 also has a business data storage unit 121 for storing various data related to the business operator, and an AI model storage unit 122 for storing learning data and a learning model that the AI ​​(artificial intelligence) has learned from the learning data. A database (not shown) containing various data may be built outside of the memory unit 120 or the management terminal 100.

[0022] The control unit 130 controls the overall operation of the management terminal 100 by executing a program stored in the memory 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 external terminals such as the business terminal 200, an image analysis unit 132 that analyzes image data such as invoice information received from the business terminal and calculates greenhouse gas emissions, a cause analysis unit 133 that analyzes the image data and analyzes the causes of time-series changes in greenhouse gas emissions calculated based on the information contained in the extracted invoice information, a transaction processing unit 134 that aggregates information on greenhouse gas emissions for a predetermined period, generates a hash value, and records it as transaction information on the blockchain network, and a report generation unit 135 that generates and transmits report data to the business operator at predetermined intervals to output greenhouse gas emissions and the results of the cause analysis of changes in emissions.

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

[0024] Furthermore, the management terminal 100 also has a wallet (not shown) necessary for recording transaction information to the blockchain network. This wallet may also be located outside the management terminal 100.

[0025] Figure 3 is a functional block diagram of the business terminals that make up the emissions management system.

[0026] The carrier terminal 200 comprises a communication unit 210, a display and 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 performed using a communication protocol such as TCP / IP.

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

[0029] The memory unit 230 stores programs for executing various control processes and functions within the control unit 240, input data, etc., and is composed of RAM, ROM, etc. The memory 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 programs stored in the memory unit 230, and is composed of a CPU, GPU, etc.

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

[0032] The business data 1000 shown in Figure 4 stores various data related to a business obtained from the business via the business terminal 200. In Figure 4, for the sake of explanation, an example of one business (a business identified by business ID "10001") is shown, but information for multiple businesses can be stored. Various data related to a business can include, for example, basic business information (e.g., the business's corporate name, username, business information (e.g., address information for each business), network name (e.g., SSID, IP address), image information (e.g., background image of the business, person image, etc.), industry, contact information, email address, business name, affiliate company name, names of related businesses in the supply chain, etc.), input information (e.g., image data of invoice information, etc.), analysis information (e.g., information on invoices extracted from image data, greenhouse gas emissions, predictions of the causes of changes in greenhouse gas emissions, etc.), customer information (e.g., customer ID, blockchain address, etc.), and offset report information (e.g., TXID, NFTID, etc.), and greenhouse gas emission reduction target data (e.g., reduction target value, reduction measure information, etc.).

[0033] Figure 8 is a flowchart illustrating an example of the greenhouse gas emission calculation process according to the first embodiment of the present invention.

[0034] First, as part 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 via the network NW from the business operator terminal 200. The business operator uploads invoices, receipts, slips, etc. (collectively referred to as "invoices" in this embodiment) to the management terminal 100 via the business operator terminal 200 in file formats such as PDF, Excel, and JPG (collectively referred to as "image data" in this embodiment). 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 storage unit 120.

[0035] Next, as part of 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 and extracts items included in the invoice information as structured string data, using a learning model that was generated in advance by learning from image data of various types of invoices stored in the AI ​​model storage unit 122 of the memory unit 120. Here, for image analysis, it is also possible to use an image analysis engine (OCR engine, etc.) provided by a business other than the management terminal 100, which is linked via API.

[0036] Image analysis is performed, for example, by recognizing and extracting text from image data containing invoice information, as shown in Figure 5. As shown in Figure 5, invoice information can include various items contained in an invoice, such as the name of the breakdown of electricity charges, the amount for each breakdown (yen), contracted power (kW), electricity usage for each breakdown (kWh), total amount (yen), and date (year and month). In this example, an invoice breakdown for electricity charges is used as an example, but it could also be an invoice for charges related to the use of other energy, including gas and fuel, or an invoice breakdown for other items, such as a receipt for travel expenses for business trips, a receipt for employee commuting expenses, an invoice related to a transaction with a freight carrier, or an invoice related to a transaction with a waste disposal company. The image analysis unit 132 can extract monetary information, activity level information, etc., contained in the invoice information as text by analyzing the image data of this invoice information. The extracted invoice information is stored as analysis information in the business data storage unit 121 of the storage unit 120. In this way, machine learning-based image analysis allows businesses to acquire a vast amount of necessary information for calculating greenhouse gas emissions as image data without having to manually input invoice information. Furthermore, highly accurate image recognition enables the precise extraction of information necessary for calculating greenhouse gas emissions, thereby improving the efficiency and accuracy of greenhouse gas emission calculations.

[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. Here, greenhouse gas emissions are classified into SCOPE1, SCOPE2, and SCOPE3. SCOPE1 is direct emissions of greenhouse gases by the business operator itself (e.g., emissions associated with fuel combustion and industrial processes), SCOPE2 is indirect emissions associated with the use of electricity, heat, gas, etc. supplied to the business operator by other companies, and SCOPE3 is the calculation standard for emissions across an organization's entire supply chain issued by the GHG Protocol, and refers to emissions from the business operator's supply chain (the entire flow including raw material procurement, manufacturing, logistics, sales, disposal, etc.). SCOPE3 is further classified into 15 categories: (1) Products / Services Purchased, (2) Capital Goods, (3) Fuel and Energy-Related Activities Not Included in SCOPE1 and SCOPE2, (4) Transportation and Distribution (Upstream), (5) Business Waste, (6) Business Travel, (7) Employee Commuting, (8) Leased Assets (Upstream), (9) Transportation and Distribution (Downstream), (10) Processing of Products Sold, (11) Use of Products Sold, (12) Disposal of Products Sold, (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 in this embodiment, CO2 will be used as an example.

[0038] Furthermore, greenhouse gas emissions are calculated by defining activity levels as the amount of electricity used by a business operator, the amount of goods transported, the amount of waste processed, and the value of various transactions, and multiplying these activity levels by emission intensity, which is the amount of CO2 emissions per 1 kWh of electricity used, the amount of CO2 emissions per ton of goods transported, and the amount of CO2 emissions per ton of waste incinerated. Greenhouse gas emissions are calculated separately for SCOPE1, SCOPE2, and SCOPE3 (SCOPE3 is further divided into 15 categories), and the total emissions are calculated as supply chain emissions.

[0039] In this embodiment, the image analysis unit 132 extracts relevant invoice information separately for SCOPE1, SCOPE2, and SCOPE3 (and further for SCOPE3, by category), and calculates emissions based on the above calculation method, for example, based on the amount of electricity used in kWh from the invoice information. The calculated emissions are stored as analysis information in the business operator data storage unit 121 of the storage unit 120.

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

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

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

[0043] Next, as part of step S202, the cause analysis unit 133 analyzes and predicts the causes of changes in emissions using machine learning based on the emission information referenced above. Here, in the cause analysis, the cause analysis unit 133 of the control unit 130 of the management terminal 100 predicts the causes of changes in emissions for each SCOPE (and further for each category in the case of SCOPE 3) using the emission information referenced above, factors that affect changes (increases and decreases) in emissions, and a learning model that was generated by learning data on factors that affect changes (increases and decreases) in emissions stored in the AI ​​model storage unit 122 of the memory unit 120 in advance.

[0044] Here, factors that influence changes (increases or decreases) in emissions include, for example, weather, temperature, product demand and / or factory operations, store or factory business hours or operating hours, changes in equipment or facilities, software measures, energy-saving activities, fuel switching, energy menu changes, changes in business or commuting volume, and the amount of electricity generated by private power generation. Each of these factors affects the emissions of one of the SCOPEs. For example, the weather factor affects precipitation, wind speed, sunshine hours, and temperature. Precipitation affects small-scale hydroelectric power generation, wind speed affects wind power generation, sunshine hours affect solar power generation, and temperature affects air conditioning. Furthermore, electricity generation affects private power generation, which affects CO2 emissions from electricity, thereby influencing changes in SCOPE2 emissions. Meanwhile, air conditioning affects gas consumption, which affects CO2 emissions from gas combustion, thereby influencing changes in SCOPE1 emissions. In addition, energy-saving activities, factory operations due to product demand, and business hours affect electricity consumption and thus affect SCOPE2. Furthermore, EMS, replacement of refrigeration equipment, introduction of energy-saving equipment, and vehicle usage also affect electricity usage and thus influence SCOPE2. In addition, vehicle usage, fuel efficiency, boiler usage, and boiler efficiency affect fuel usage, which in turn affect CO2 emissions from fuel and thus influence SCOPE1.

[0045] Furthermore, the number of products sold influences categories 1, 9, 10, 11, and 12 of SCOPE3, while capital investment influences category 2, renewable energy ratio and procured energy volume influence category 3, the number of deliveries and changes in delivery routes influence categories 4 and 9, product loss rate influences category 5, business travelers and office workers influence category 6, commuters and office employees influence category 7, power consumption influences category 8, processing reduction through product improvements influences category 10, improvements to energy-saving products influence category 11, increased recycling rates influence category 12, tenant office electricity influences category 13, franchise emissions influence category 14, and investment destination emissions influence category 15.

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

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

[0048] Figure 10 is a flowchart illustrating an example of transaction processing for greenhouse gas emissions according to the first embodiment of the present invention.

[0049] First, as part 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 storage unit 120. The business operator data referred to here includes business operator analysis information (greenhouse gas emissions for each SCOPE), etc.

[0050] Next, as part of 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 hash value for one row using a hash function for greenhouse gas emissions over a predetermined period, and records the hash value as transaction information on 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, thus forming the blockchain. In this example, in order to reduce the cost of blockchain recording, the data is recorded on a Layer 2 (e.g., a sidechain) that is different from the main blockchain (so-called Layer 1).

[0051] Furthermore, the transaction processing unit 134 can assign and manage NFTIDs in conjunction with the blockchain record of the business operator's greenhouse gas emissions. More specifically, as shown in Figure 4, the business operator data 1000 can be assigned the business operator's customer ID as customer information, store the blockchain address to be referenced, and assign NFTIDs and TXIDs as offset report information.

[0052] As shown in Figure 6, on the blockchain network, each NFTID is associated with a blockchain address, and the NFTID and customer ID are managed on the management terminal 100. For example, information on greenhouse gas emissions for a business corresponding to customer ID "2" can be accessed by referring to the blockchain address for each NFTID, such as NFTID "13" and "14," and as shown in Figure 7, detailed emission information can be retrieved. Figure 7 shows information on an offset report associated with NFTID "14," where a TXID is assigned, and the offset report includes CO2 emissions by SCOPE, the target year and month, and the report issuance date. In addition to the CO2 emissions for the target year and month in this example, it is also possible to create NFTs of CO2 emissions for the most recent year, reduced CO2 emissions, and offset CO2 emissions. By managing CO2 emissions as NFTs in this way, businesses can trade NFT certificates while ensuring non-tampering and transaction reliability, and can also provide proof of emissions to third parties.

[0053] Figure 11 is a flowchart illustrating an example of the greenhouse gas emission calculation process according to a second embodiment of the present invention.

[0054] Recently, an organization called CDP (Carbon Disclosure Project) has been collecting information by issuing questionnaires to companies regarding their carbon dioxide emissions and efforts to address climate change, and disclosing this information. Its activities have gained the support of institutional investors interested in climate change and are expanding year by year. CDP's objective is to "maintain a healthy and prosperous economy for people and the planet," and to achieve this objective, CDP works with investors, companies, and local governments to encourage the disclosure of information regarding their environmental impact. The information collected by CDP has a significant impact on the decision-making of investors, companies, and policymakers around the world. However, when CDP evaluates companies, the fairness of the scoring of responses is not guaranteed. CDP responses include hundreds of items, and input errors are common when companies try to answer all of them. While the format of the input content (text, numbers, etc.) can be checked, the current situation is that even if there are input errors in the content itself, the response is submitted as is. For example, when similar questions appear in responses for the entire company or for each region, inconsistencies in the answers can occur. More specifically, in response to questions about reduction targets, comments may be made in a way that does not lead to reductions, or in response to questions about total Scope 1 emissions worldwide, there may be mathematical and semantic inconsistencies between the breakdown of total emissions and the emissions by country / region.

[0055] To mitigate errors in responses due to such inconsistencies, this embodiment describes a method that can correct inconsistencies in responses to questions intended for reports such as CDPs and generate appropriate responses.

[0056] First, as part of the process in step S401, the report generation unit 135 of the control unit 130 of the management terminal 100, when receiving response data regarding response text or numerical values ​​from the business operator via the business operator terminal 200, refers to the data on the business operator's greenhouse gas emissions stored in the business operator data storage unit 121 of the storage unit 120. As described above, this data also includes information on target values ​​and / or reduction measures regarding the amount of greenhouse gas emissions reduction for the business operator.

[0057] Next, as part of step S402, the report generation unit 135 of the control unit 130 checks for any inconsistencies in the response data based on the response data received from the business operator and the referenced greenhouse gas emission data. In the example above, regarding the greenhouse gas emission target value entered by the business operator, it can be checked whether the comments entered by the business operator include comments on reduction amounts and reduction measures that can be achieved with the entered target value. Furthermore, regarding the total emissions of Scope 1, it can be checked whether the sum of the total emissions entered by the business operator matches the sum of emissions for each country / region.

[0058] Next, as part of the processing in step S403, if the control unit 130's report generation unit 135 detects a discrepancy in the above step, it generates a revised response data containing the correct response text or numerical value and sends it to the business terminal 200, thereby recommending the revised response to the business. For example, the report generation unit 135 can revise the numerical value of the reduction target based on the data on reduction targets stored in the storage unit 120, or generate a revised response text that revises the wording or numerical value related to the reduction amount and / or reduction measures. Alternatively, the report generation unit 135 can generate a revised response text that revises the numerical value so that the total emissions of Scope 1 and the total emissions by country, etc., match. In this case, the report generation unit 135 can also refer to publicly available information such as reports on greenhouse gas emissions and / or industry trends disclosed by the business, not limited to the data on greenhouse gas emissions stored in the storage unit 120, by methods such as web crawling. Furthermore, if the report generation unit 135 detects a contradiction, it can also send an alert to the operator terminal 200 indicating that a contradiction has been detected, and / or the comment or numerical value related to the detected contradiction, either along with a proposed correction.

[0059] Furthermore, as part of the processing in step S404, the report generation unit 135 recommends the above-mentioned revised response and, as an option, can also present improvement suggestions to enhance the evaluation (CDP scoring) based on the response. For example, it can specifically suggest areas in the response that are likely to improve the score. Alternatively, the report generation unit 135 can recommend, along with the response, that third-party verification be conducted regarding Scope 1 and 2 or Scope 11 to 3, and the scope of the target organization, and can execute a process to request verification from a third party along with a deadline, in response to a request from the business terminal 200. Alternatively, to improve the efficiency of response verification, the report generation unit 135 can also send log data regarding greenhouse gas emissions to the business terminal 200. Alternatively, the report generation unit 135 can make suggestions such as, "If you take action regarding Scope 3 categories X, Y, and Z, your score will improve." Accordingly, in response to a request from the business terminal 200, it can also automatically generate a questionnaire for supply chain operators and send it to the business terminal 200. Furthermore, the report generation unit 135 can obtain responses from supply chain operators and reflect that content in the response text. In addition, it can automatically generate wording that indicates that the score will improve if the quantification of risks and opportunities in accordance with TCFD is described, by using machine learning to analyze the industry, business type, and circumstances of the operators. For example, it can generate a learning model by using machine learning to analyze the results from the previous year that were higher than the expected score for companies in a similar industry, business type, and sales scale, and then generate the response text based on that learning model.

[0060] In this way, by helping businesses identify inconsistencies in their responses to questions posed to organizations such as CDPs and assisting them in generating appropriate responses, greenhouse gas emission management can be efficiently and appropriately managed.

[0061] The embodiments described above are merely illustrative to facilitate understanding of the present invention and are not intended to limit its interpretation. The present invention can be modified and improved without departing from its spirit, and it goes without saying that the present invention includes equivalents thereof. [Explanation of Symbols]
