Problems to be Solved by the Invention

[0005] However, although the technology disclosed in Non-Patent Document 1 discloses a method for calculating greenhouse gas emissions related to SCOPE3, etc., for each business operator, especially in enterprises and local governments, etc., a huge amount of data collection and input is required for calculating emissions, calculating the emissions, and managing the calculation results, which consumes a great deal of labor and time. In particular, in the field of GHG emissions management, the SCOPE of emissions to be calculated is expanding, the data on which emissions calculations are based vary widely for each SCOPE, and the data management methods also differ for each business operator. Therefore, the introduction of advanced technologies for improving business efficiency has been delayed.

Embodiments for Carrying Out the Invention

[0010] The contents of the embodiments of the present invention will be listed and described. The greenhouse gas emission management system (hereinafter simply referred to as "system") according to the embodiment of the present invention has the following configuration. [Item 1] A method for managing water quality and drainage volume, The control unit of the management terminal, receives input data for calculating drainage volume from the operator terminal of the operator, refers to the past input data by the operator, and recommends data for complementing the received input data based on the past input data. [Item 2] The input data for calculating the displacement is the method described in Item 1, including coefficients and units for classification, item, and type. [Item 3] The method described in Item 1 of displaying the data to be supplemented via the chat interface of the operator terminal. [Item 4] The method described in Item 1, wherein the data to be supplemented includes data for supplementing omissions in the input data or data for correcting errors in the input data.

[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 for explaining a greenhouse gas emission management system according to a first embodiment of the present invention.

[0013] As shown in FIG. 1, in the emission management system 1 in the present embodiment, the administrator terminal 100 and a plurality of 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 operator and input information (e.g., image data of invoice information) for calculating the greenhouse gas (e.g., CO2) emission amount from the operator terminals 200A and 200B.

[0015] Further, the management terminal 100 analyzes the received image data of the invoice information by machine learning, extracts the necessary items of the invoice information included in the image data, and calculates the emission amount of the greenhouse gas. Further, the management terminal 100 analyzes the change (e.g., increase or decrease) in the greenhouse gas emission amount over time calculated by machine learning and predicts the cause of the change.

[0016] Furthermore, the management terminal 100 has a wallet and is connected to the public blockchain network NW. Based on the information regarding the greenhouse gas emissions for each of the above-specified periods, 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 immediately preceding block, and the nonce value mined by a node, and is recorded following the immediately preceding block, forming a blockchain. Here, the above hash generation and / or the recording of the transaction information on the blockchain can also be performed not by the management terminal 100 but via another terminal. In this case, the management terminal 100 transmits the greenhouse gas emissions calculated by the matching process to the other terminal. Furthermore, the management terminal 100 can record the information regarding the greenhouse gas emissions on the blockchain network as a smart contract. By using a smart contract, based on the information regarding the above emissions, a contract regarding the emissions trading with other operators can be automatically generated, approved, and executed without the intervention of a third party. Also, with a smart contract, each operator can refer to the transaction information without going through the management terminal, enhancing service convenience and reducing operation costs. Furthermore, the management terminal 100 connects to a large language model (LLM, for example, GPT) 300 via the network and via an API (Applicaton Progamming Interface) to receive a predetermined question text from another terminal, analyze the question text, and generate an answer text.

[0017] Here, as described above, in a public blockchain, since the approval of transactions is performed not by a specific administrator but by an unspecified number of nodes or miners, compared with a private blockchain, higher data immutability and fault tolerance can be ensured. Therefore, since the security of transactions is ensured, it is preferable to use a public blockchain as the destination for recording power transactions in this embodiment. Representative public blockchains include Bitcoin, Ethereum, etc. For example, Ethereum has higher immutability and reliability among public blockchains.

[0018] In addition, the management terminal 100 can associate information regarding greenhouse gas emissions with an identifier or the like and record it as a non-fungible token (Non-Fungible Token (hereinafter, "NFT")) on the blockchain network. An NFT is, for example, a token issued according to the "ERC721" standard of Etherium, which is a platform of the blockchain network, and is a unit of data recorded on the blockchain network, having a non-fungible nature. Since an NFT is recorded on the blockchain together with a smart contract and is traceable, it can prove transaction information including details and history such as the information of the operator managing the greenhouse gas emissions.

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

[0020] The communication unit 110 is a communication interface for communicating with an external terminal via the 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 programs for executing various control processes and each function within the control unit 130, input data, etc., and is composed of a RAM (Random Access Memory), a ROM (Read Only Memory), etc. Further, the storage unit 120 has a business operator data storage unit 121 that stores various data related to business operators, and an AI model storage unit 122 that stores learning data and a learning model obtained by having AI (Artificial Intelligence) learn the learning data. Note that a database (not shown) storing 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 the programs stored in the storage unit 120, and is composed of a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), etc. As functions of the control unit 130, there are an information reception unit 131 that receives information from external terminals 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 the greenhouse gas emissions, a cause analysis unit 133 that analyzes the cause of the time-series change in the greenhouse gas emissions calculated based on the information included in the extracted invoice information by analyzing the image data, a transaction processing unit 134 that generates a hash value by summarizing information related to the greenhouse gas emissions for a predetermined period and performs a process of recording it as transaction information in the blockchain network, and a report generation unit 135 that generates and transmits report data for outputting the greenhouse gas emissions and the result of the cause analysis of the change in the emissions to the business operator every predetermined period.

[0023] Further, although not shown, the control unit 130 has an image generation unit and generates screen information displayed via a user interface of an external terminal such as the operator terminal 200. For example, using the images and text data stored in the storage unit 120 as materials, various images and texts are arranged in a predetermined area of the user interface based on a predetermined layout rule, thereby generating the information displayed on the user interface. The processing related to the image generation unit can also be executed by a GPU (Graphics Processing Unit).

[0024] In addition, the management terminal 100 further has a (not shown) wallet necessary for recording transaction information in the blockchain network. Note that this wallet can also be provided outside the management terminal 100.

[0025] FIG. 3 is a functional block diagram of an operator terminal constituting an 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 performed according to a communication protocol such as TCP / IP.

[0028] The display operation unit 220 is a user interface used for an operator to input instructions and display texts, images, etc. according to input data from the control unit 240. When the operator terminal 200 is configured by a personal computer, it is composed of a display, a keyboard, and a mouse. When the operator terminal 200 is configured by a smartphone or a tablet terminal, it is composed of a touch panel or the like. 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 computer).

[0029] The storage unit 230 stores various control processes, programs for executing each function in the control unit 240, input data, etc., and is composed of a RAM, a ROM, etc. Further, the storage unit 230 temporarily stores the communication content with the management terminal 100.

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

[0031] FIG. 4 is a diagram for explaining the 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. In FIG. 4, for convenience of explanation, an example of one business operator (the business operator identified by the business operator ID "10001") is shown, but information of a plurality of business operators can be stored. Examples of various data related to the business operator include, for example, basic information of the business operator (for example, corporate name of the business operator, user name, office information (for example, address information for each office, etc.), network name (for example, SSID, IP address, etc.), image information (for example, background image of the office, portrait image, etc.), business type, contact information, email address, office name, related company name, business operator name related on the supply chain, etc.), input information (for example, image data of invoice information, etc.), analysis information (for example, information related to invoices extracted from image data, greenhouse gas emissions, prediction of the cause of changes in greenhouse gas emissions, etc.), customer information (for example, customer ID, blockchain address, etc.), and offset report information (for example, TXID, NFTID, etc.), activity information (credit information held, information on the type / origin of credit assigned to a project (product) / raw material and the offset amount).

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

[0034] First, as the process of step S101, the information acquisition unit 131 of the control unit 130 of the management terminal 100 acquires, from the business operator terminal 200 via the network NW, image data including bill information collected on the business operator side. The business operator uploads bills, receipts, vouchers, etc. (collectively referred to as "bills" in this embodiment) to the management terminal 100 in file formats such as PDF, Excel, JPG, etc. (collectively referred to as "image data" in this embodiment) via the business operator terminal 200. 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] Subsequently, as the process 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 by machine learning. Here, when performing image analysis, a method called so-called OCR is used. 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 generated in advance by learning the image data of bills in a plurality of various formats stored in the AI model storage unit 122 of the storage unit 120, and extracts the items included in the bill information as structured string data. Here, when performing image analysis, it is also possible to use an image analysis engine (such as an OCR engine) provided by a business operator other than the management terminal 100 and linked by an API.

[0036] Regarding image analysis, for example, as shown in FIG. 5, it is performed by recognizing and extracting text from image data including claim information. As shown in FIG. 5, examples of claim information include various items included in the claim. For example, items such as the breakdown name of the electricity bill, the amount (yen) for each breakdown, the contract power (kW), the electricity consumption (kWh) for each breakdown, the total amount (yen), the date (year and month), etc. are included. In this example, the breakdown of the electricity bill is illustrated, but it may be a claim for the usage fee of other energies including gas and fuel in addition to electricity, or alternatively, for example, a receipt for transportation expenses for business trips, a receipt for commuter expenses of employees, a claim accompanying transactions with freight forwarders, or a breakdown of a claim accompanying transactions with waste operators. The image analysis unit 132 can extract, as text, the amount information, the following activity amount information, etc. included in the claim information by analyzing the image data of these claim information. The extracted claim information is stored as analysis information in the operator data storage unit 121 of the storage unit 120. In this way, through image analysis by machine learning, without the operator inputting claim information manually, etc., a huge amount of necessary information for calculating greenhouse gas emissions can be obtained as image data, and through highly accurate image recognition, the information necessary for calculating greenhouse gas emissions can be accurately extracted. Therefore, it is possible to achieve the efficiency improvement and high accuracy of the calculation of greenhouse gas emissions.

[0037] Next, in step S103, the image analysis unit 132 of the control unit 130 calculates the greenhouse gas emissions based on the invoice information extracted from the image data. Here, the greenhouse gas emissions are classified into SCOPE1, SCOPE2, and SCOPE3. SCOPE1 refers to the direct emissions of greenhouse gases by the operator itself (for example, emissions associated with fuel combustion and industrial processes). SCOPE2 refers to the indirect emissions associated with the use of electricity, heat, gas, etc. supplied from other companies to the operator. Furthermore, SCOPE3 is the calculation standard for the emissions of the entire supply chain of an organization issued by the GHG Protocol, referring to the emissions of the operator's supply chain (the entire series of processes such as raw material procurement, manufacturing, logistics, sales, and disposal). SCOPE3 is further classified into 15 categories: (1) purchased products / services, (2) capital goods, (3) fuel and energy-related activities not included in SCOPE1 and SCOPE2, (4) transportation, distribution (upstream), (5) waste from the business, (6) business trips, (7) commuting of employees, (8) leased assets (upstream), (9) transportation, 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, the greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3). In this embodiment, CO2 will be taken as an example for explanation.

[0038] Also, the greenhouse gas emissions are calculated by defining the electricity consumption, cargo transportation volume, waste treatment volume, and various transaction amounts of the operator as activity volumes, and multiplying the activity volumes by the emission factors, namely, the CO2 emissions per 1 kWh of electricity used, the CO2 emissions per 1 ton of cargo transported, and the CO2 emissions per 1 ton of waste incinerated. The greenhouse gas emissions are calculated separately for the above SCOPE1, SCOPE2, and SCOPE3 (for SCOPE3, by category of the 15 categories), and the total emissions are calculated as the supply chain emissions.

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

[0040] Subsequently, as the process of step S104, the report generation unit 135 of the control unit 130 generates a visualized report showing the breakdown of emissions over time for each SCOPE (for SCOPE3, further categorized by category) based on the information regarding the calculated emissions.

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

[0042] First, as the process of step S201, the cause analysis unit 133 of the control unit 130 of the management terminal 100 refers to the information regarding the emissions of greenhouse gases of the operator calculated in step S103 of FIG. 8. Here, regarding the emissions of greenhouse gases, the emissions for each SCOPE (for SCOPE3, further categorized by category) are referred to. Also, the cause analysis unit 133 can confirm the change (increase or decrease) in emissions by referring to the past emissions data of the same operator for the emissions of greenhouse gases. As described above, the emissions are stored as analysis information in the operator data storage unit 121 of the storage unit 120.

[0043] Subsequently, as the process of step S202, based on the information regarding the above-mentioned reference emissions, the cause analysis unit 133 analyzes and predicts the cause of the change in emissions by machine learning. Here, in the cause analysis, the cause analysis unit 133 of the control unit 130 of the management terminal 100 uses the above-mentioned reference emissions information, factors that affect the change (increase or decrease) in emissions, and a learning model generated by learning data regarding factors that affect the change (increase or decrease) in emissions and stored in the AI model storage unit 122 of the storage unit 120 to predict the cause of the change in emissions for each SCOPE (for SCOPE3, further categorized by category).

[0044] Here, as factors that affect the change (increase or decrease) in emissions, for example, factors such as weather, temperature, product demand and / or factory operation, store or factory business or operation hours, equipment or facility changes, software-based measures, power-saving actions, fuel conversion, energy menu changes, changes in business trips or commuting volume, and the power generation amount of self-generation can be cited. Each of these factors is a factor that affects the emissions of any SCOPE. For example, the factor of weather affects precipitation, wind volume, sunshine hours, and temperature. Precipitation affects small hydropower generation amount, wind volume affects wind power generation amount, sunshine hours affect solar power generation amount, temperature affects air conditioning, and furthermore, the power generation amount affects the self-generation amount, and the self-generation amount affects the CO2 emissions amount by electricity, thereby affecting the change in the emissions of SCOPE2. On the other hand, air conditioning affects gas usage amount, and the gas usage amount affects the CO2 emissions amount by gas combustion, thereby affecting the change in the emissions of SCOPE1. Also, power-saving activities, factory operation due to product demand, and business hours affect power usage amount and affect SCOPE2. Also, EMS, replacement of refrigeration equipment, introduction of energy-saving equipment, and automobile usage amount also affect power usage amount and affect SCOPE2. In addition, automobile usage amount, fuel consumption, boiler usage amount, and boiler efficiency affect fuel usage amount and affect the CO2 emissions amount by fuel, thereby affecting SCOPE1.

[0045] In addition, the factor of product sales volume affects Categories 1, 9, 10, 11, and 12 of SCOPE3, equipment investment affects Category 2, the renewable energy ratio and the amount of procured energy affect Category 3, the number of transportation trips and transportation route changes affect Categories 4 and 9, the product loss rate affects Category 5, the number of business trips and the number of employees going to the office affect Category 6, the number of commuting employees and the number of employees going to the office affect Category 7, the power consumption affects Category 8, the reduction of processing due to product improvement affects Category 10, the improvement to energy-saving products affects Category 11, the increase in the recycling rate affects Category 12, the office power of tenants affects Category 13, the emissions of franchises affect Category 14, and the emissions of investment destinations affect Category 15 respectively.

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

[0047] Subsequently, as the process of step S203, the report generation unit 135 of the control unit 130 generates a visualized report on the cause of the change in emissions for each SCOPE (and further for each category in the case of SCOPE3) based on the information on the predicted cause of the change in emissions analyzed above.

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

[0049] First, as 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 storage unit 120. Here, the business operator data to be referred to includes the analysis information of the business operator (greenhouse gas emissions for each SCOPE), etc.

[0050] Next, as the process of step S302, the transaction processing unit 134 generates a hash value based on the operator data referred to in step S301. That is, the transaction processing unit 134 generates a hash value for one line using a hash function for the greenhouse gas emissions during a predetermined period, and records the hash value as transaction information in the public blockchain. On the blockchain network, a block is generated based on the transaction information, the hash value recorded in the immediately preceding block, and the nonce value mined by the node, is recorded following the immediately preceding block, and a blockchain is formed. Here, in this example, in order to reduce the cost related to blockchain recording, it is assumed that the recording is made in layer 2 (for example, a side chain) different from the main blockchain (so-called layer 1).

[0051] In addition, the transaction processing unit 134 can assign and manage an NFT ID in association with the blockchain record of the operator's greenhouse gas emissions. More specifically, as shown in FIG. 4, in the operator data 1000, the customer ID of the operator is assigned as customer information, the blockchain address to be referred to is stored, and the NFT ID and TX ID can be assigned as offset report information.

[0052] As shown in FIG. 6, on the blockchain network, blockchain addresses are associated with each NFT ID. In the management terminal 100, NFT IDs and customer IDs are managed. For example, information on the greenhouse gas emissions of a business operator corresponding to customer ID "2" can be obtained by referring to the blockchain addresses for each NFT ID, such as NFT IDs "13" and "14". As shown in FIG. 7, the details of the emissions information can be read. FIG. 7 shows information related to the offset report associated with NFT ID "14". A TXID is assigned in association with the offset report, and the CO2 emissions by SCOPE, the target year and month, and the report issue date are included in the offset report. In addition to the CO2 emissions for the target year and month in this example, the CO2 emissions for the most recent years, the reduced CO2 emissions, and the offset CO2 emissions can also be NFTized. By managing CO2 emissions as NFTs in this way, business operators can conduct transactions of NFTized certificates in a state where non-falsification and transaction reliability are ensured, and can also prove the emissions to third parties.

[0053] FIG. 11 is a flowchart showing an example of recommending data for complementing input data for calculating drainage volume according to the first embodiment of the present invention. Conventionally, for calculating the drainage volume of business operators, there was a mechanism of multiplying the water volume by the drainage unit and calculating. However, for this calculation, it was necessary to manually input classifications (water intake, drainage), items (surface water, groundwater, rainwater, tap water, etc.), drainage units, unit amounts, etc. as IDs in a calculation format such as CSV or Excel. Furthermore, when manually inputting, there was a problem that if there was an input error, an error would be displayed and the correct drainage volume could not be calculated. Therefore, in this embodiment, it is characterized by automatically complementing during manual input by utilizing an AI function and a notification function as follows.

[0054] First, as the process of step S401, the information acquisition unit 131 of the control unit 130 of the management terminal 100 receives input data for calculating the drainage volume from the business operator terminal 200. The person in charge of the business operator inputs the activity name, keywords (such as river names), quantity, and unit via CSV or Excel displayed on the business operator terminal 200. Also, as another embodiment, the person in charge of the business operator should originally input all of the classification (water intake, drainage), item (surface water, groundwater, rainwater, tap water, etc.), drainage volume original unit, and unit quantity associated with the original unit via CSV or Excel displayed on the business operator terminal 200. However, input data in a state where any one of these is not input is accepted. In addition, this process can also be used to send the input data to the LLM300 via the chat interface displayed on the business operator terminal 200.

[0055] Subsequently, as the process of step S402, the report generation unit 135 of the control unit 130 of the management terminal 100 refers to the past input data of the business operator data 1000 in the business operator data storage unit 121 of the storage unit 120, and for example, when the drainage volume original unit or the unit quantity associated with the original unit based on the activity volume of the business operator is insufficient in the input data, estimates the drainage volume and unit quantity to be supplemented. Similarly, referring to the past input data of the business operator, it is estimated whether there are any abnormalities or deficiencies in the numerical values and contents input by the business operator this time. For example, when there is a misrecording in the input data, the correct data is estimated. In addition, this process can also be executed by the management terminal 100 via the LLM300. The LLM300, similar to the above, refers to the data regarding the past input data of the business operator, for example, estimates the drainage volume unit, or estimates whether there are any abnormalities or deficiencies in the numerical value input by the business operator this time, and sends the result to the management terminal 100.

[0056] Subsequently, as the process of step S403, the report generation unit 135 of the control unit 130 of the management terminal 100 transmits the data generated in the management terminal 100 or the LLM 300 in the process of the above S402 to the business operator terminal 200. The person in charge of the business operator can confirm the unit amount associated with the drainage unit and the unit cost received by the business operator terminal 200 and the recommended information based on the verification result in a form displayed via the interface or pop-up display of the business operator terminal 200. After receiving the above data, the person in charge of the business operator complements the input content based on the received content. The above interface includes being displayed in ways such as selection by natural conversation on the chat screen, selection by button display on the chat screen, individual selection by the pre-registration pop-up on the system screen, and batch selection by the pre-registration pop-up on the system screen.

[0057] As described above, with the automatic completion function of the input data for calculating the drainage volume by the person in charge of the business operator, error-free and efficient input can be realized.

[0058] The above-described embodiments are merely examples for facilitating the understanding of the present invention and are not for limiting and interpreting the present invention. It goes without saying that the present invention can be changed and improved without departing from its gist, and equivalents of the present invention are included therein.
