Description

Technical Field

[0001] The present invention relates to a carbon footprint tracking and management system, which can accurately calculate and track the carbon footprint and methods in the product manufacturing process. Background Art

[0002] Traditionally, enterprises usually manage the renewable energy certification of products by inputting the supply rate of renewable energy and the input amounts of raw materials and components, so as to evaluate their environmental impact. However, this approach has obvious limitations. Especially when it comes to electric energy, due to different power generation methods (such as fossil fuels, nuclear energy, renewable energy, etc.), the carbon emissions per unit of electric energy will vary significantly and also change over time.

[0003] Existing management systems often ignore the specific sources of electric energy and their related carbon emission differences, so they cannot comprehensively and accurately reflect the true carbon footprint in the product manufacturing process. In addition, these systems lack transparency and data immutability, making the authenticity and reliability of information questioned.

[0004] To overcome these problems, a new solution is needed that can more precisely measure the carbon emissions during product manufacturing and ensure the secure storage and sharing of relevant information. Summary of the Invention

[0005] The purpose of the present invention is to provide a carbon footprint tracking and management system and method, aiming to solve the problems of inaccurate calculation of carbon emissions, lack of transparency of information, and insufficient data security in the traditional product manufacturing process. The system realizes the comprehensive monitoring and management of carbon emissions throughout the entire life cycle of products from raw material procurement to finished product warehousing by integrating advanced information technology and blockchain technology.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions: A carbon footprint tracking and management system includes an information processing module, at least one information collection terminal, and at least one user terminal; The information processing module includes a calculation unit, a communication unit, and a storage unit; the calculation unit can obtain the product key information and carbon emission coefficients of each manufactured product from the information collection terminal and calculate the carbon emissions of each product; the calculation unit is a node of the blockchain network and registers the product key information and carbon emissions in the blockchain; the storage unit is used to save system programs, application programs, embedded software, and processing results; the calculation unit is used to associate the product key information and the calculated carbon emissions with the product code and store them in the storage unit; the calculation unit also includes the function of calculating the carbon emissions of components; the communication unit is used to send the calculated carbon emission information as product certification information to the user terminal.

[0007] A further improvement of the present invention is that when a product is ordered, the calculation unit compares the expected carbon emissions with the actual carbon emissions during the product manufacturing process. If the actual emissions are greater than the expected emissions, carbon credits equivalent to the difference are read from the storage unit, associated with the product code, and stored in the storage unit.

[0008] A further improvement of the present invention is that the key product information includes manufacturing time, product specifications, product weight, product dimensions, product quantity, and product chemical composition.

[0009] A further improvement of the present invention is that when the carbon emission coefficient for the current year has not been determined, the publicly announced target value of the power company is used as the carbon dioxide emission coefficient for the current year.

[0010] A further improvement of the present invention is that the communication unit supports wired and wireless communications.

[0011] A further improvement of the present invention is that the storage unit also has a product information database for recording the key information of all products and their corresponding carbon emission data.

[0012] A further improvement of the present invention is that the product includes at least one finished component.

[0013] A carbon footprint tracking and management method includes: Step 1, information collection: The operator of the information collection terminal first enters relevant key product information through the input device; meanwhile, the calculation unit obtains the latest carbon emission coefficient from external resources. Step 2, carbon emission calculation: Based on the collected information, the calculation unit calculates the actual carbon emissions of each product batch; if the official carbon emission coefficient for the current year has not been announced, the publicly announced target value of the power company is used as a temporary reference. Step 3, data association and storage: After the calculation is completed, the calculation unit associates the key product information and carbon emissions with the corresponding product code and stores them in the product information database in the storage unit. Step 4, information registration and sharing: To ensure the security and immutability of the data, the calculation unit registers the data in Step 3 into the blockchain network. Step 5, credit offset mechanism: When it is detected that the actual carbon emissions exceed the expected value specified by the customer, the calculation unit deducts the corresponding share from the pre-stored carbon credit limit and updates it to the database. Step 6, information release: The calculation unit generates a product certification document containing detailed carbon footprint information and sends it to the user terminal through the communication unit.

[0014] A further improvement of the present invention lies in that the key product information includes manufacturing time, product specifications, product weight, product size, product quantity, and product chemical composition.

[0015] A further improvement of the present invention lies in that the communication unit supports wired and wireless communications.

[0016] Compared with the prior art, the present invention has at least the following beneficial technical effects: A carbon footprint tracking and management system and method provided by the present invention, through blockchain technology, the calculation unit registers the key product information and carbon emissions in the blockchain. The immutability of the blockchain ensures the authenticity and integrity of the data, making the carbon footprint information of the product transparent and traceable to everyone. This helps to enhance consumers' trust in the product as they can verify the environmental protection attributes of the product. The present invention can accurately calculate the carbon emissions of each product. By obtaining the key product information and carbon emission coefficients from the information collection terminal, the calculation unit can perform precise calculations to ensure the accuracy of the carbon emissions. This accuracy is crucial for formulating effective carbon emission reduction strategies and meeting regulatory requirements. The present invention integrates an information processing module, an information collection terminal, and a user terminal to form a complete carbon footprint tracking and management system. This comprehensive management enables enterprises to more comprehensively understand the carbon footprint of their products, thereby formulating more effective environmental protection strategies. The calculation unit not only calculates the carbon emissions but also associates the key product information and the calculated carbon emissions with the product code and stores them in the storage unit. This automated processing improves work efficiency and reduces the possibility of human errors. The present invention is designed to be scalable and can easily add more information collection terminals and user terminals. This enables the system to adapt to the growth of enterprise scale and changes in business requirements without major technical upgrades or modifications. The communication unit sends the calculated carbon emission information as product certification information to the user terminal, enabling users to conveniently obtain the carbon footprint information of the product. This user-friendly design enhances the user experience and promotes the popularization of environmental protection awareness. The calculation unit also includes the function of calculating the carbon emissions of components, which enables the system to more meticulously analyze the carbon footprint of the product. For products composed of multiple components, this meticulous analysis helps to identify potential areas for carbon emission reduction, thereby formulating more specific emission reduction measures.

[0030] Embodiments of the present invention will be described in detail below with reference to the drawings.

[0031] Embodiment 1 The carbon footprint tracking and management system of the present invention will achieve accurate calculation, transparent management and secure storage of carbon emissions during the product manufacturing process.

[0032] System architecture: As Figure 1As shown in the figure, the carbon footprint tracking and management system of the present invention mainly consists of an information processing module, at least one information collection terminal, and at least one user terminal. The information processing module includes a calculation unit, a communication unit, and a storage unit, and can communicate with at least one information collection terminal in real time. The information collection terminal is set at the production site and is responsible for collecting key information of each product batch, such as manufacturing time, product specifications, weight, size, quantity, and chemical composition, etc.; while the user terminal is used to receive operation instructions from the orderer, obtain and display the carbon footprint data of specific products.

[0033] Precise calculation: One of the core functions of the present invention is to automatically calculate the actual carbon emissions of each product based on the collected key information of the product and its corresponding carbon emission coefficient. In particular, when the official carbon emission coefficient for the current year has not been announced, the system will use the target value publicly disclosed by the power company as a temporary reference standard to ensure that effective assessment work can continue even under uncertain conditions. In addition, for complex products composed of multiple components, the system also has the ability to independently account for the carbon emissions of each part, thus achieving more refined management.

[0034] Application of blockchain technology: In order to enhance the security and reliability of the system, the information processing unit is designed as a node in the blockchain network. This means that all registered information will be recorded in the form of a distributed ledger, which not only ensures the immutability of the data, but also improves the transparency of the entire process. This helps to build consumers' confidence in the enterprise's environmental protection commitment and promotes trust and cooperation across industries.

[0035] Dynamic adjustment mechanism: When a customer places an order to purchase a certain product, the system will automatically compare the ideal carbon emission level set in the order with the value generated during the actual production process. If it is found that the standard is exceeded, the corresponding share can be deducted from the pre-accumulated carbon credit quota and associated with the corresponding product code. This not only reflects the enterprise's positive attitude towards fulfilling its emission reduction obligations, but also provides buyers with more opportunities to choose low-carbon products.

[0036] Flexible expansion ability: Considering that the specific needs of different enterprises may vary, the present invention supports multiple configuration options. For example, the information processing module can be set in an internal private cloud environment or connected to a public cloud service; at the same time, it can also be seamlessly docked with other related systems (such as ERP or MES) to form an integrated solution. This modular design concept makes the solution highly adaptable and scalable.

[0037] User experience optimization: The user interface is friendly and intuitive, allowing non-professionals to easily complete tasks such as query and analysis. Both manufacturers and end consumers can quickly and easily obtain the required information, such as viewing the specific carbon footprint report of a product batch or comparing the performance differences between different suppliers. In addition, with the support of mobile devices, users can even access these data resources at any time while on the go.

[0038] Regulatory compliance: As governments around the world step up their efforts to regulate greenhouse gas emissions, compliance with relevant laws and regulations becomes increasingly important. To this end, the present invention strictly follows internationally accepted standards and guidelines to ensure that all reports generated comply with the latest policy requirements. This is of great significance in helping companies avoid potential legal risks and improve their market competitiveness.

[0039] Its main features include the following aspects: 1. System composition like Figure 1 As shown, the carbon footprint tracking and management system provided by the present invention is mainly composed of an information processing module, at least one information collection terminal and at least one user terminal. The information processing module is connected to multiple information collection terminals and user terminals through a network to achieve two-way communication of data. The network connection can be in the form of a mobile communication network, the Internet or a fixed communication network. The information processing module can adopt a cloud computing system or other computer system, and can be configured as a dedicated facility or a shared facility as needed.

[0040] 2. Information processing module The information processing module includes a computing unit, a communication unit and a storage unit (see Figure 2 ). The computing unit is responsible for the operation control of the entire system, and it contains processors such as CPU and circuits. The communication unit supports wired and wireless communications, covering a variety of standards and technologies, such as 5G, Bluetooth, etc. The storage unit is used to save important data such as system programs, applications, embedded software, and processing results. In addition, the storage unit also specially designs a product information database to record the key information of all products and their corresponding carbon emission data.

[0041] 3. Information collection terminal Information collection terminals are usually set up in factories and other production sites to collect key information for each product batch. This information includes but is not limited to: product batch number, actual manufacturing time, specifications, weight, size, quantity, chemical composition and strength, etc. Information collection terminals can be in the form of PCs, smart phones, tablets and other devices to ensure that operators can easily enter and view relevant information. Its hardware structure includes computing units, communication units, storage units, cameras, displays, input and output devices and other parts.

[0042] 4. User Terminal The user terminal provides a user-friendly platform for customers who order products, enabling them to easily obtain and understand the carbon footprint information of the purchased products. Its hardware structure is similar to that of the information collection terminal, including a computing unit, a communication unit, a storage unit, a camera, a display, input and output devices, etc. Users can submit order requests through this terminal and specify the desired carbon dioxide emission level; the system will feedback the corresponding carbon emission report according to the actual production situation.

[0043] 5. Calculation Process Step 1, Information Collection: The operator of the information collection terminal first enters the relevant key product information through the input device. At the same time, the computing unit also obtains the latest carbon emission coefficients from external resources. The above operations complete the reading of data S1 in the appendix. Figure 3 in the appendix.

[0044] Step 2, Carbon Emission Calculation: Based on the information collected above, the computing unit calculates the actual carbon emissions of each product batch. If the official carbon emission coefficients for the current year have not been announced, the target values publicly available from the power company are used as a temporary reference. The above operations complete the calculation of carbon emissions S2 in the appendix. Figure 3 in the appendix.

[0045] Step 3, Data Association and Storage: After the calculation is completed, the computing unit associates the key product information and carbon emissions with the corresponding product codes and stores them in the product information database in the storage unit. The above operations complete the association of product codes S3 in the appendix. Figure 3 in the appendix.

[0046] Step 4, Information Registration and Sharing: To ensure the security and immutability of the data, the computing unit also registers the data in Step 3 into the blockchain network. This enables all nodes to access the same version of the data without relying on a central administrator.

[0047] Step 5, Credit Offset Mechanism: When it is detected that the actual carbon emissions exceed the expected value specified by the customer, the computing unit automatically deducts the corresponding share from the pre-stored carbon credit quota and updates it in the database. This process helps enterprises take proactive measures to reduce their environmental impact.

[0048] Step 6, Information Release: Finally, the computing unit generates a product certification document containing detailed carbon footprint information and sends it to the user terminal through the communication unit for the customer to review, that is, the above operations complete the output result S4 in the attached figure.

[0049] 6. Supplementary Explanation Flexibility and scalability: Considering the special needs of different industries, the present invention allows a certain degree of customized development. For example, the information processing module can be deployed either in a private cloud environment or connected to a public cloud service; at the same time, it can also be seamlessly integrated with other business systems to form a more complete solution.

[0050] User experience optimization: Both manufacturers and consumers can enjoy a simple and intuitive operation experience. Especially with the support of mobile devices, users can query the required information anytime and anywhere, greatly improving convenience.

Prefabricated cabin application: 8 units (emission reduction coefficient of 0.78 tCO2 / unit) Step 2, Carbon Emission Calculation: Based on the information collected above, the calculation unit 11 calculates the actual carbon emissions of each product batch. If the official carbon emission coefficients for the current year have not been announced, the publicly available target values of the power company are used as a temporary reference. The above operations complete the calculated carbon emissions S2 in Figure 3 the attached

[0055] During the carbon emission calculation process, dynamic coefficient loading is required. The dynamic coefficient loading is carried out in the following ways: 1. Call the API of the National Climate Center to obtain: Regional baseline emission factor: 0.583 kgCO2 / kWh (East China region 2024 version); Power generation rights carbon emission reduction coefficient: 0.314 kgCO2 / kWh (gas power replacing coal power).

[0056] 2. When it is detected that the official data has not been updated: Automatically switch to the recommended value of the State Grid (with version identification); Trigger an email to notify the management for review.

[0057] Step 3, Data Association and Storage: After the calculation is completed, the calculation unit 11 associates the key product information and carbon emissions with the corresponding product codes and stores them in the product information database in the storage unit 13. The above operations complete the associated product code S3 in Figure 3 the attached

[0058] Step 4, Information Registration and Sharing: To ensure the security and immutability of data, the computing unit 11 also registers the data in Step 3 into the blockchain network, thus completing the blockchain evidence storage. This enables all nodes to access the same version of the data without relying on a central administrator.

[0059] The process of completing blockchain evidence storage includes the following steps: 1. Generate a unique project code: CEQ-2025-ZJ-500kV-0032.

[0061] 3. Generate a digital fingerprint through the national cryptographic SM3 algorithm.

[0062] 4. Write to the energy blockchain (transaction confirmation time < 3s).

[0063] Step 5, Credit Offset Mechanism: When it is detected that the actual carbon emissions exceed the expected value specified by the customer, the computing unit will automatically deduct the corresponding share from the pre-stored carbon credit quota and update it to the database. This process helps enterprises take proactive measures to reduce their environmental impact.

[0064] The credit offset mechanism includes the following steps: 1. Compare the designed emission reduction target (the committed emission reduction amount at the time of project establishment is 82,000 tons).

[0065] 2. Actually calculate the total emission reduction amount: 83,456 tons.

[0066] 3. The excess part (5,456 tons) is automatically transferred.

[0067] 4. 40% is transferred to the enterprise's carbon account (CCER account).

[0068] 5. 60% enters the public emission reduction pool (for power grid emergency regulation).

[0069] Step 6, Information Release: Finally, the computing unit 11 generates a product certification document containing detailed carbon footprint information and sends it to the user terminal 3 through the communication unit 12 for the customer to view. That is, the above operation completes the output result S4 in Figure 3 the attachment.

[0070] The output results for multiple terminals are as follows: 1.
