Description

Technical Field

[0001] This invention relates to the field of carbon neutrality technology, and in particular to a blockchain-based carbon neutrality evidence storage system. Background Technology

[0002] Carbon neutrality refers to the process by which an enterprise, organization, or individual calculates the total amount of greenhouse gas emissions it directly or indirectly generates within a certain period of time and offsets its own carbon dioxide emissions through afforestation, energy conservation, and emission reduction, thereby achieving "zero emissions" of carbon dioxide.

[0003] However, the carbon neutrality process has the following problems: Neutralization projects often involve many processes and steps, require multi-disciplinary collaboration, and have certain technical barriers. To ensure the credibility of the neutralization results, it is necessary to improve the infrastructure and invest a lot of information technology funds, which makes the overall cost to users high. In addition, the information on carbon sinks is registered through the official website and not disclosed to external companies, so other personnel cannot view it.

[0004] For example, a carbon neutrality intelligent monitoring and management system, as described in Chinese patent application number CN202121580082.3, provides a technical solution including a carbon emission data detection module, a central control module, an intelligent alarm module, an information transmission module, and a monitoring terminal. The carbon emission data detection module is used to collect real-time data on the activity levels of fossil fuel consumption, raw material consumption, clinker production, and purchased or exported electricity and heat related to greenhouse gas emissions during the production process of industrial enterprises. The central control module is used to receive carbon emission data signals sent by the carbon emission data detection module, output alarm signals to the intelligent alarm module, and periodically send monitoring data to the monitoring terminal. The intelligent alarm module is used to issue alarm reminders when carbon emissions are abnormal. The information transmission module is used for data communication between the central control module and the monitoring terminal. The monitoring terminal is used for remote monitoring of carbon emissions and the carbon neutrality process.

[0005] This carbon neutrality intelligent monitoring and management system has a simple structure, stable communication, and enables users to keep abreast of dynamic information on carbon emission data, providing effective data for carbon neutrality and management to improve the efficiency of carbon neutrality and management.

[0006] However, the above technical solutions are mainly for real-time collection of fuel consumption in the production process of industrial enterprises. They cannot be used by individuals or other people who do not consume fuel, nor can they be used for carbon neutrality certificate management. They cannot provide users with services such as self-application, real-time calculation, online neutralization and on-chain storage.

[0007] In summary, a new technical solution is needed to address the aforementioned technical problems. Summary of the Invention

[0008] This application provides a blockchain-based carbon neutrality notarization system, comprising:

[0009] Interface Management Module: Used to connect with the B-end scenario platform and realize communication between the B-end scenario platform, including receiving carbon emission orders sent by the B-end scenario platform, receiving instructions from the B-end scenario platform to query the balance of emission reduction projects and verification instructions, and sending back carbon neutrality certificate to the B-end scenario platform.

[0010] Order module: Used to process each carbon emission order sent by the B-end scenario platform, match the scenario of each carbon emission order with the methodology calculation model, and calculate the carbon emission of each carbon emission order according to the methodology calculation model corresponding to each carbon emission order.

[0011] The transaction process management module is used to manage the cancellation and verification of emission reduction projects purchased by B-end scenario platforms. After purchasing emission reduction projects in the carbon market trading system, B-end scenario platforms upload transaction certificates and cancellation certificates to the transaction process management module to form available transaction volume and cancellation volume. The cancellation volume is available for C-end customers to achieve carbon neutrality.

[0012] Cancellation Project Management Module: After each carbon emission order and cancellation amount is carbon neutralized, the cancellation amount decreases synchronously, and the corresponding neutralization amount increases synchronously. After the B-end scenario platform successfully issues a certificate to the C-end customer, the neutralization amount between the C-end customer and the B-end scenario platform is formed.

[0013] Methodological Calculation Model Module: Set up the corresponding methodological calculation model according to the activity level to calculate the carbon emissions of C-end customers and the project emission reduction required for carbon neutrality;

[0014] Carbon neutrality and management module: Used to implement carbon neutrality and management for each carbon emission order, determine whether the C-end customer has achieved carbon neutrality, and send certificates and record the carbon neutrality amount of the scenario for C-end customers who have achieved carbon neutrality.

[0015] Certificate Management Module: Generates carbon neutrality certificates for C-end customers whose orders on the B-end scenario platform have achieved carbon neutrality, and sends the certificates to the C-end customers through the B-end scenario platform;

[0016] Traceability Management Module: Establishes a unique traceability display template for each B-end scenario party to record user basic information, carbon emission verification information, project emission reduction cancellation certificate information and certificate information;

[0017] On-chain management module: The system centrally processes the content displayed in the traceability display template for on-chain processing; (The system supports manual and automatic on-chain processing. Manual on-chain processing uses manual operation to process data on-chain, while automatic on-chain processing uses a system timed task to process data that has not yet been on-chain.) After successful on-chain processing, the content displayed in the traceability display template will be uploaded to the blockchain for notarization to ensure that the data is not tampered with, and a unique traceability code will be generated on the carbon neutrality notarization certificate.

[0018] QR code management module: By scanning the traceability code on the certificate, you can view all the content displayed on the traceability display template.

[0019] As a preferred embodiment, the calculation formula of the methodological calculation model is: C = A * B;

[0020] Where A represents the activity level, B represents the emission factor, and C represents the emission amount, with the unit being kgCO2.

[0021] As a preferred option, the evidence is created based on blockchain technology.

[0022] As a preferred option, a blockchain-based carbon neutrality evidence storage system also includes an online verification and management module, where a third-party verification agency verifies the carbon emissions of each carbon emission order online, and issues a third-party verification report after the verification is completed.

[0023] As a preferred option, a blockchain-based carbon neutrality record system also includes a carbon account system, which accumulates and stores carbon emissions and carbon neutrality based on the carbon emission and carbon neutrality behavior of end-users.

[0024] As a preferred solution, a blockchain carbon neutrality evidence storage system also includes a carbon account management module: used to record carbon emissions and carbon neutrality data of B-end scenario platforms and C-end customers, and to record the low-carbon contributions and carbon reduction responsibilities of B-end scenario platforms and C-end customers.

[0025] As a preferred embodiment, the blockchain carbon neutrality evidence storage system further includes a manual input module, which comprises an order input module, an offline behavior input module, and an inventory management module. Data from the order input module and the offline behavior input module is stored in the inventory management module. Data input from the order input module is transmitted to the order module, and data from the offline behavior input module is transmitted to the methodology calculation model module for processing.

[0026] As a preferred embodiment, the blockchain carbon neutrality evidence storage system also includes a reconciliation management module, in which the B-end scenario platform and the reconciliation management module conduct daily reconciliation management of order quantity, carbon emission data, carbon neutrality data, and the number of carbon neutrality evidence storage certificates.

[0027] As a preferred embodiment, the blockchain carbon neutrality evidence storage system also includes an early warning management module. When the remaining amount of cancelled projects reaches a certain value, the early warning management module will issue an early warning.

[0028] When this invention serves customers, the B-end scenario platform first cancels the emission reduction trading volume purchased by the B-end scenario platform through the transaction process management module. After cancellation, the C-end customer can purchase it for individual carbon neutrality. The C-end customer platform places an order through the B-end scenario platform. The B-end scenario platform collects the C-end customer's behavioral data, such as refueling volume and abandoning the use of disposable chopsticks when ordering food. The methodological calculation model module calculates the C-end customer's carbon emissions. After carbon neutralization by carbon emissions and available cancellation volume, the carbon neutrality and management module determines whether the C-end customer has achieved carbon neutrality. When a customer achieves carbon neutrality, a carbon neutrality certificate is issued. The traceability management module displays various data such as name, behavior, emissions, and neutrality data. All content displayed in the traceability management module is then processed on the blockchain for notarization, ensuring that the data is not tampered with. At the same time, a unique traceability code is generated on the certificate. By scanning the traceability code on the certificate, all content displayed in the traceability management module can be viewed. The immutability and traceability characteristics of blockchain are applied to carbon neutrality practice, making the carbon neutrality process open and transparent, and relevant records can be traced and verified at any time.

[0029] This application serves B-end platforms while also connecting to C-end users by accessing individual consumer carbon emission data. It enables the calculation of individual carbon emission behavior, recording of carbon neutrality contributions, and the issuance of carbon neutrality certificates. This application facilitates individual carbon neutrality certificate management, providing C-end customers with services such as self-application, real-time calculation, online neutralization, and linked evidence storage. By enhancing the traceability and verification of environmental rights cancellation and providing access to real-time transaction and cancellation data, it helps enterprises easily integrate the system. Furthermore, the system applies the immutable and traceable characteristics of blockchain technology to carbon neutrality practices, making the carbon neutrality process open and transparent, with relevant records readily traceable and verifiable.

[0033] The following provides a detailed description of specific embodiments of the present invention; it should be noted that the specific embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the present invention.

[0034] Example 1:

[0035] This embodiment provides a blockchain-based carbon neutrality notarization system, including:

[0036] Interface Management Module: Used to connect with the B-end scenario platform and realize communication between the B-end scenario platform, including receiving carbon emission orders sent by the B-end scenario platform, receiving instructions from the B-end scenario platform to query the balance of emission reduction projects and verification instructions, sending back carbon neutrality certificate to the B-end scenario platform, and sending back invoices to the B-end scenario platform, etc. The B-end scenario platform is an intermediary platform, such as Alipay, WeChat and other intermediary platforms.

[0037] Order Module: This module processes each carbon emission order sent by the B-end platform. It calculates the carbon emission amount for each order based on the corresponding methodology and calculation model matching the carbon emission order scenario. If the order does not meet the minimum neutrality requirement, a notification is issued, and SMS and email alerts are sent to the B-end platform, C-end customers, and transaction personnel. Carbon emission amounts are represented through carbon emission data, such as fuel purchase data and coal purchase data.

[0038] Inventory module: Match the listing quantity of projects according to the total value to match projects with the minimum value; for example, if the B-end scenario platform has two cancelled projects, one with 100 tons remaining and the other with 10 tons remaining, and the carbon emission reduction of the C-end customer is calculated to be 1 ton, then the cancelled project with 10 tons remaining is preferred to ensure that the project with the smaller quantity is neutralized first, as shown in Table 1.

[0039] Table 1 Available Cancellation Item Inventory

[0040]

[0041] The transaction process management module manages the cancellation and verification of emission reduction projects purchased by B-end scenario platforms. After purchasing emission reduction projects in the carbon market trading system, B-end scenario platforms can simultaneously upload transaction certificates and cancellation certificates to the transaction process management module, forming available transaction volume and cancellation volume. The available cancellation volume is available for C-end customers to achieve carbon neutrality.

[0042] Cancellation Project Management Module: After each carbon emission order and available cancellation amount are carbon neutralized, the cancellation amount decreases synchronously, and the corresponding neutralization amount increases synchronously. After the B-end scenario platform successfully issues a certificate to the C-end customer, the neutralization amount between the C-end customer and the B-end scenario platform is formed.

[0043] Methodological Calculation Model Module: Based on the activity level, a corresponding methodological calculation model is set to calculate the carbon emissions of C-end customers and the project emission reductions required for carbon neutrality; where activity level can also be referred to as carbon emission behavior; as a preferred option, the calculation formula of the methodological calculation model is: C = A * B; where A represents the activity level (also referred to as carbon emission behavior), B represents the emission factor, and C represents the emission amount, in kgCO2; for example, when it is electricity, the unit of emission factor is degrees, and the value of B is 581gCO2e / kWh; the activity level is the carbon emission behavior of C-end customers, such as carbon emission data such as C-end customers' refueling data and electricity purchase data. The above data can be directly obtained by the authorized C-end customer platform, such as during offline transactions, or can be entered by the customer themselves; the methodological calculation model module calculates the carbon emissions, neutralizes them with the required project emission reductions, and puts them on the blockchain, and finally sends a carbon neutrality certificate to the C-end customer;

[0044] Carbon neutrality and management module: used to manage each order, determine whether the C-end customer has achieved carbon neutrality, send certificates to C-end customers who have achieved carbon neutrality and record the carbon neutrality amount of the scenario party, as shown in Table 2;

[0045] Table 2 Carbon Accounts for Scenario Parties

[0046]

[0047] Certificate Management Module: Generates carbon neutrality certificates for C-end customers whose orders on the B-end scenario platform have achieved carbon neutrality, and sends the certificates to C-end customers through the B-end scenario platform. Preferably, in order to improve the security of the certificates, the certificates are made based on blockchain technology. The information stored in the certificate management module is shown in Table 3.

[0048] Table 3

[0049]

[0050] Preferably, a blockchain carbon neutrality evidence storage system also includes a traceability management module: establishing a unique traceability display template for each B-end scenario platform, setting up a template display process, and using it to record user basic information, carbon emission verification information, project emission reduction cancellation certificate information, and certificate information.

[0051] Traceability Management Module: A unique traceability display template is created for each B-end scenario party to record user basic information, carbon emission verification information, project emission reduction cancellation certificate information and certificate information; as shown in Table 4;

[0052] Table 4 Contents of the Traceability Management Module

[0053]

[0054]

[0055] On-chain management module: The system centrally processes the content displayed in the traceability display template for on-chain processing; the system supports manual and automatic on-chain processing. Manual on-chain processing is performed by manually operating the data on the blockchain, while automatic on-chain processing is performed by the system's scheduled tasks to process data that has not yet been on-chain. After successful on-chain processing, the content displayed in the traceability display template will be uploaded to the blockchain for notarization to ensure that the data is not tampered with, and a unique traceability code will be generated on the carbon neutrality notarization certificate.

[0056] The QR code management module allows users to scan the traceability code on the certificate to view all the content displayed on the traceability template. This means they can view all the data related to the carbon neutrality process for each order, such as... Figure 1 As shown.

[0057] Preferably, a blockchain carbon neutrality evidence storage system further includes a carbon account system, which accumulates and stores carbon emissions and carbon neutrality based on the carbon emission and carbon neutrality behavior of C-end customers; more preferably, a blockchain carbon neutrality evidence storage system further includes a carbon account management module: used to record the carbon emission and carbon neutrality data of B-end scenario platforms and C-end customers, and to define the low-carbon contributions and carbon reduction responsibilities of B-end scenario platforms and C-end customers.

[0058] Preferably, the blockchain carbon neutrality evidence storage system further includes a reconciliation management module, in which the B-end scenario platform and the reconciliation management module conduct daily reconciliation management of order quantity, carbon emission data, carbon neutrality data, and the number of carbon neutrality evidence storage certificates; the reconciliation management module is connected to the B-end scenario platform through an interface management module or a standard interface.

[0059] Preferably, the blockchain carbon neutrality evidence storage system also includes an early warning management module. When the remaining amount of cancelled projects reaches a certain value, the early warning management module will issue an early warning. It can also notify system operators and B-end scenario platform personnel via SMS and email, prompting them to purchase emission reduction projects in a timely manner to prevent C-end customers from being unable to place orders. The early warning management module is connected to the B-end scenario platform through an interface management module or a standard interface.

[0060] In this embodiment, the B-end platform first cancels the emission reduction trading volume purchased by the B-end platform through the transaction process management module. After cancellation, the C-end customer can purchase it for individual carbon neutrality. The C-end customer platform places an order through the B-end platform. The B-end platform collects the C-end customer's behavioral data, such as refueling volume and abandoning the use of disposable chopsticks when ordering food. The methodological calculation model module calculates the C-end customer's carbon emissions. After carbon neutralization by carbon emissions and available cancellation volume, the carbon neutrality and management module determines whether the C-end customer has achieved carbon neutrality. Upon achieving carbon neutrality, a carbon neutrality certificate is issued to the customer. The traceability management module displays various data such as name, behavior, emissions, and neutrality data. All content displayed in the traceability management module is then processed on the blockchain for notarization, ensuring that the data is not tampered with. At the same time, a unique traceability code is generated on the certificate. By scanning the traceability code on the certificate, all content displayed in the traceability management module can be viewed. The immutability and traceability characteristics of blockchain are applied to carbon neutrality practice, making the carbon neutrality process open and transparent, and relevant records can be traced and verified at any time.

[0061] Example 2:

[0062] To improve data accuracy, this embodiment includes an online verification management module, where a third-party verification agency conducts real-time or manual verification of carbon emission amounts for each carbon emission order online. The carbon emission amount includes the methodology calculation model, activity data, and carbon emission data. A third-party verification report is issued after the verification is completed. The third-party verification agency is a qualified auditing organization.

[0063] Example 3:

[0064] In this embodiment, the blockchain carbon neutrality evidence storage system further includes a manual input module, which includes an order input module, an offline behavior input module, and an inventory management module. Data from the order input module and the offline behavior input module is stored in the inventory management module. Data input from the order input module is transmitted to the order module, and data from the offline behavior input module is transmitted to the methodology calculation model module for processing.

[0065] In this embodiment, the order entry module is used to automatically enter the emission reduction transaction volume of B-end customer platforms that are not connected to this application. It can directly achieve connection with this application. The data entered by the order entry module is stored in the inventory management module and then transmitted to the order entry module for processing.

[0066] The offline behavior entry module is used to record the offline behavior of B-end customers, including emission reduction behavior and emission behavior, such as offline refueling payment, not using disposable parameters when dining, and low-carbon travel by bicycle. The data entered through the offline behavior entry module is stored in the inventory management module and then transmitted to the methodology calculation model module for processing.

[0067] In summary, the certificate issuance models in this application are mainly divided into three types:

[0068] The first type is the orders received by the order module and the behavioral data received by the methodology calculation model module. Both are received automatically, meaning that all data from the B-end scenario is collected and processed in real time by the C-end customer through authorization, and certificates are sent automatically.

[0069] The second type is the order data received by the order module and the behavioral data received by the methodology calculation model module. The order data is exported from the B-end platform and then imported into the platform of this application offline via file. In this case, part of the data is collected through the C-end customer platform, while the other part is manually entered to achieve semi-automatic certificate sending.

[0070] The third type involves orders being manually entered into the order entry module by the B-end party, and all behavioral data being manually entered into the offline behavioral entry module and then into the methodology calculation model module. In this case, all data is manually entered, enabling manual certificate sending. Before the data is entered, a third-party verification agency completes the verification work offline and issues a corresponding verification report.

[0071] Replacing traditional fuel vehicles with new energy vehicles can also reduce carbon emissions. For example, new energy vehicle users can scan a code to charge their vehicles through a mini-program on the C-end customer platform or pre-purchase charging electricity for their new energy vehicles. Once the charging amount reaches 100 kWh or more, they can receive a carbon neutrality certificate from the system. This application is of great significance in calling on citizens to pay attention to "dual carbon" and join the carbon neutrality movement.

[0072] In summary, by adopting the above-mentioned technical solutions, this application serves B-end scenario platforms while also accessing individual consumer carbon emission behavior data around the C-end. This enables the calculation of individual carbon emission behavior and the recording of carbon neutrality contributions, as well as the issuance of carbon neutrality certificates. This application can realize the management of individual carbon neutrality certificates and provide C-end customers with services such as self-application, real-time calculation, online neutralization, and linked certificate storage.
