Mode for Carrying Out the Invention

[0010] The content of the embodiment of the present invention will be listed and explained. 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 greenhouse gas emissions, The control unit of the management terminal, receives an inquiry regarding an increase or decrease in the greenhouse gas emissions of the operator from the operator terminal of the operator, refers to data regarding the greenhouse gas emissions of the operator, and transmits a response sentence regarding an increase or decrease in the greenhouse gas emissions of the operator to the operator terminal. [Item 2] The control unit transmits a question regarding whether to perform a periodic report on the increase or decrease in the greenhouse gas emissions of the operator to the operator terminal, which is the management method described in Item 1. [Item 3] The management method described in Item 1, wherein the inquiry is received via the chat interface of the operator terminal. [Item 4] The management method described in Item 1, wherein the inquiry regarding the increase or decrease in greenhouse gas emissions includes any one of inquiries regarding weekly, monthly, and annual increases or decreases of the operator. [Item 5] The management method described in Item 1, wherein the periodic report includes any one of reports regarding weekly, monthly, and annual increases or decreases of the operator.

[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 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 connected to each other via a communication network NW.

[0014] For example, the management terminal 100 receives basic information regarding the operator and input information (for example, image data of invoice information) for calculating the greenhouse gas (for example, CO2) emissions 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 necessary items of the invoice information included in the image data, and calculates the greenhouse gas emissions. In addition, the management terminal 100 analyzes the calculated change (for example, increase or decrease) in greenhouse gas emissions over time 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-mentioned predetermined periods, the management terminal 100 generates a single hash value using SHA256 or other hash functions and records it as transaction information in the blockchain network. On the blockchain network, based on the transaction information, the hash value recorded in the previous block, and the nonce value mined by the node, this block is generated, recorded following the previous block, and a blockchain is formed. Here, the above hash generation and / or the recording of the transaction information in the blockchain can also be performed not by the management terminal 100 but via other terminals. In this case, the management terminal 100 transmits the greenhouse gas emissions calculated by the matching process to the other terminals. Furthermore, the management terminal 100 can record the information regarding the greenhouse gas emissions in the blockchain network as a smart contract. By using the smart contract, based on the above-mentioned information regarding the 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 the smart contract, each operator can refer to the transaction information without going through the management terminal, improving the service convenience and reducing the operation cost. Furthermore, the management terminal 100 connects to a large language model (LLM, for example, GPT) 300 that receives a predetermined question text from other terminals via an API (Applicaton Progamming Interface) via the network, analyzes the question text, and generates an answer text.

[0017] Here, as described above, since the public blockchain has transactions approved not by a specific administrator but by an unspecified number of nodes or miners, it can ensure higher data immutability and fault tolerance compared to the private blockchain. 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 and Ethereum. 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 referred to as "NFT") in the blockchain network. The NFT is, for example, a token issued according to the "ERC721" standard of Etherium, which is the platform of the blockchain network, and is a unit of data recorded in the blockchain network, having a non-fungible nature. The NFT is recorded on the blockchain together with a smart contract and is traceable, so 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 emissions 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 in 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 learned by AI (Artificial Intelligence) from 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 of 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 on 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 results of the cause analysis of the change in 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 to be displayed via a user interface of an external terminal such as the business 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 to be displayed on the user interface. The processing related to the image generation unit can also be executed by a GPU (Graphics Processing Unit).

[0024] Further, the management terminal 100 further has a (not shown) wallet necessary for recording transaction information with respect to 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 the business operator terminal constituting the emission management system.

[0026] The business 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 a business operator to input instructions and display texts, images, etc. according to input data from the control unit 240. When the business operator terminal 200 is configured by a personal computer, it is composed of a display, a keyboard, and a mouse. When the business 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 business operator terminal 200 which is a computer (electronic computer).

[0029] The storage unit 230 stores programs for executing various control processes and 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 the 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. As various data related to the business operator, 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, etc.), business type, contact information, email address, office name, related company name, names of business operators related in 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) can be included.

[0033] FIG. 8 is a flowchart diagram showing an example of the calculation process of the 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 invoice information collected on the business operator side. The business operator uploads invoices, receipts, vouchers, etc. (collectively referred to as "invoices" 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 by previously learning image data of invoices in a plurality of various formats stored in the AI model storage unit 122 of the storage unit 120, and extracts items included in the invoice 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 that is linked via 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, 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. 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 other examples such as a receipt for transportation expenses for business trips, a receipt for commuting 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 the amount information, the following activity amount information, etc. included in the claim information as text by analyzing the image data of these claim information. The extracted claim information is stored as analysis information in the business operator data storage unit 121 of the storage unit 120. In this way, through image analysis by machine learning, without the business operator inputting claim information manually or otherwise, a vast 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, so that the efficiency and high accuracy of calculating greenhouse gas emissions can be realized.

[0037] Next, in step S103, the image analysis unit 132 of the control unit 130 calculates the greenhouse gas emissions based on the claim 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, and further, 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 waste 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, (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), and in this embodiment, CO2 will be used as an example for explanation.

[0038] Also, the greenhouse gas emissions are defined by taking the electricity consumption, cargo transportation volume, waste treatment volume, and various transaction amounts of the operator as the 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 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 (and for SCOPE3, further categorized by category). Among the claim information, for example, based on the electricity consumption in kWh, the emission amount is calculated based on the above calculation method. The calculated emission amount is 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 the emission amounts over time for each SCOPE (and for SCOPE3, further categorized by category) based on the information regarding the calculated emission amounts.

[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 greenhouse gas emission amount of the operator calculated in step S103 of FIG. 8. Here, regarding the greenhouse gas emission amount, the emission amounts for each SCOPE (and for SCOPE3, further categorized by category) are referred to. Also, the cause analysis unit 133 can confirm the change (increase or decrease) in the emission amount by referring to the past emission amount data of the same operator for the greenhouse gas emission amount. As described above, the emission amount is stored as analysis information in the operator data storage unit 121 of the storage unit 120.

[0043] Subsequently, as the process of step S202, the cause analysis unit 133 analyzes and predicts the cause of the change in the emission amount by machine learning based on the information regarding the emission amount referred to above. Here, in the cause analysis, the cause analysis unit 133 of the control unit 130 of the management terminal 100 learns the information on the emission amount referred to above, the factors affecting the change (increase or decrease) in the emission amount, and the data regarding the factors affecting the change (increase or decrease) in the emission amount, which was generated in advance and stored in the AI model storage unit 122 of the storage unit 120, and predicts the cause of the change in the emission amount for each SCOPE (for SCOPE3, further categorized by category) using the learned model.

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

[0045] In addition, the factor of the number of products sold 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 changes in transportation routes affect Categories 4 and 9, the product loss rate affects Category 5, the number of business trips and the number of office visits affect Category 6, the number of commuters and the number of office employees affect Category 7, power consumption affects Category 8, reduction of processing due to product improvement affects Category 10, improvement to energy-saving products affects Category 11, 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 using 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 the transaction process 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 of one line for the greenhouse gas emissions during a predetermined period using a hash function, and records the hash value as transaction information in the public blockchain. On the blockchain network, based on the transaction information, the hash value recorded in the previous block, and the nonce value mined by the node, this block is generated, recorded following the previous block, and the blockchain is formed. Here, in this example, in order to reduce the cost related to the blockchain record, it is assumed that the record 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 operator's customer ID is assigned as customer information, and 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, a blockchain address is associated with each NFT ID. In the management terminal 100, the NFT ID and the customer ID are managed. Therefore, for example, information on the greenhouse gas emissions of an operator corresponding to the customer ID "2" can be obtained by referring to the blockchain address for each NFT ID, such as NFT IDs "13" and "14". As shown in FIG. 7, the details of the emission information can be read out. FIG. 7 shows information on the offset report associated with the 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 issue date of the report are included in the offset report. In addition to the CO2 emissions in the target year and month of this example, the CO2 emissions in the most recent years, the reduced CO2 emissions, and the offset CO2 emissions can also be NFTized. In this way, by managing the CO2 emissions as NFTs, the operator can conduct transactions of NFTized certificates while ensuring non-tampering and transaction reliability, and can also prove the emissions to a third party.

[0053] FIG. 11 is a flowchart showing an example of processing for inquiries regarding increases and decreases in greenhouse gas emissions of a business operator according to the first embodiment of the present invention. Conventionally, for the analysis and evaluation of increases and decreases in greenhouse gas emissions of business operators, it was necessary for the business operators themselves to compare and consider on the analysis screen of the greenhouse gas emissions management application installed on the business operator terminal. For example, even for the annual total comparison of greenhouse gas emissions, it was necessary to create a steady comparison graph as the "amount of CO2e" or a standard format equivalent thereto. Due to the need for such a standard format, the flexibility in the operation aspect, including the analysis, of the comparison of increases and decreases in greenhouse gas emissions has been impaired (for example, it is not possible to immediately grasp which one is larger in terms of the total amount rather than the amount as CO2e, or there is an annual reporting format but no monthly reporting format, etc.). Therefore, when analyzing the increases and decreases in greenhouse gas emissions ad hoc, it was necessary for the business operators themselves to output data each time, select comparison targets, and spend time (time) for analysis. Therefore, in the present embodiment, it is characterized by automating by utilizing the AI / chat function and the 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 an inquiry regarding the increase and decrease amount of greenhouse gas emissions from the business operator terminal 200. The person in charge of the business operator can input an inquiry via the chat interface displayed on the business operator terminal 200, including conditional sentences for weekly, monthly, and annual, or a combination thereof, regarding the increase and decrease amount of the greenhouse gas emissions of the business operator. In addition, the control unit 130 can create a prompt sentence (instruction sentence) with the content of "Please answer the increase and decrease amount of the greenhouse gas emissions of (the business operator) on a weekly, monthly, and annual basis" for the inquiry received from the business operator terminal 200 and send it to the LLM 300.

[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 data regarding the greenhouse gas emissions of the business operator in the business operator data storage unit 121 of the storage unit 120, and for example, performs and calculates comparisons on a weekly, monthly, and / or annual basis regarding the increase or decrease in the greenhouse gas emissions (and / or CO2e emissions) of the business operator. Also, this process can be executed by the management terminal 100 via the LLM300. Similar to the above, the LLM300 refers to the data regarding the greenhouse gas emissions of the business operator, and for example, performs and calculates comparisons on a weekly, monthly, and / or annual basis regarding the increase or decrease in the greenhouse gas emissions (and / or CO2e emissions) of the business operator, and transmits the calculation result to the management terminal 100 together with the response text to the above inquiry.

[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 response text including the data on the increase or decrease in the greenhouse gas emissions of the business operator, which was generated by the management terminal 100 or the LLM300 in the process of S402 above, to the business operator terminal 200. The person in charge of the business operator can confirm the received data on the increase or decrease in the greenhouse gas emissions in the form displayed via the chat interface of the business operator terminal 200. After receiving the above data on the increase or decrease, the person in charge of the business operator can repeatedly ask questions via the chat interface, such as "want to compare the annual increase or decrease", "want to compare the monthly increase or decrease", etc., and can also receive the increase or decrease amount and the response text generated by the management terminal 100 or the LLM300. Also, regardless of the questions asked by the person in charge of the business operator, the management terminal 100 transmits a question text such as "Do you want to issue a regular report?" to the business operator terminal 200 via the chat interface, and according to the response result from the business operator terminal 200, as a regular report, for each specified period or each predetermined period, data regarding the comparison (increase or decrease) between the current greenhouse gas emissions and the past greenhouse gas emissions is transmitted via the chat interface or via a notification function (such as a push notification).

[0057] As described above, business operators can easily refer to and analyze data on the increase or decrease in greenhouse gas emissions obtained based on the determined format through a chat interface in a simple and flexible format without the need to edit or process the data themselves.

[0058] The above-described embodiments are merely examples for facilitating the understanding of the present invention and are not intended to limit the interpretation of 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.
