Description

Technical Field

[0001] The present disclosure belongs to the field of carbon emission technology, and in particular relates to a method, system, device and storage medium for obtaining a product carbon footprint report. Background Art

[0002] Product environmental footprint and carbon footprint certification is an urgent need to accelerate green, low-carbon and high-quality development, and is an urgent need to deal with the "carbon barriers" of international trade. Carrying out certification-related research and pilot projects will effectively promote domestic companies to seize market share and create important opportunities for accelerating the cultivation of new momentum and shaping new advantages.

[0003] The EU Product Environmental Footprint (PEF) was jointly developed by the European Directorate-General for Research and the European Directorate-General for Environment. It is the EU's official life cycle assessment (LCA) standard and certification system, used to comprehensively evaluate 16 types of environmental impacts, including carbon footprint accounting and carbon labeling certification.

[0004] ISO 14067:2018 is an internationally recognized ISO standard for quantifying the carbon footprint of products. It specifies principles, requirements, and guidance for quantifying and reporting the carbon footprint of products (CFP) in a manner consistent with international life cycle assessment (LCA) standards (ISO 14040 and ISO 14044). It provides businesses with a unified approach to assessing product carbon emissions and is an effective tool for promoting the evaluation of green goods and services.

[0005] Currently, companies primarily employ third-party certification agencies to manually calculate product carbon emissions through the collection of carbon emission data using spreadsheets and on-site verification. This is inefficient and reduces accuracy. Some third-party certification agencies purchase specialized carbon emission software from abroad, but this software has high barriers to entry and is not suitable for direct operation by corporate users. It also fails to meet the current demands of the product carbon footprint market. Technically, these agencies lack user-friendly interfaces and algorithmic integrity checks on reported data.

[0026] Under current carbon footprint calculation methods, industrial and commercial users lack historical data, the calculation process is uncontrollable, and third-party organizations directly performing calculations using international software pose the risk of data leakage. Furthermore, data collection, calculation, and verification are inefficient and cannot adapt to market development.

[0027] Product Environmental Footprint software covers product management, data collection, model building, factor library management, carbon emissions reporting and inventory, and online certification. Enterprises can achieve simple, efficient, and accurate one-stop product carbon footprint accounting and analysis, and export verification reports with one click, meeting the needs of industrial and commercial users for scenarios such as export environmental disclosure of goods and product emission reduction analysis. A graphical interface also allows for model building, categorized into raw materials, production process, packaging, distribution / retail, consumer use, and disposal and recycling.

[0028] like Figure 1 As shown, the present disclosure proposes a method for obtaining a product carbon footprint report, the method comprising: Determine the life cycle of the target product; Determine the carbon footprint accounting life cycle of the target product based on the life cycle; Based on the factor library, calculate the carbon footprint and calculate the carbon emissions in each link of the life cycle; Use the product carbon footprint accounting model to identify the data type and attribute value fields of carbon emissions; Generate a carbon footprint report for the target product based on the data type identification results and the attribute value field confirmation results.

[0029] Specifically, determine the target product life cycle, including: Select target products; Obtain product information of target products; Determine the life cycle of the target product based on product information.

[0030] Specifically, based on the factor library, the carbon footprint accounting calculates the carbon emissions of each link in the life cycle, including: Obtain the emission coefficient corresponding to the carbon emissions of each link through the factor library; Obtain the consumption of target products in each link; Based on the emission coefficient and consumption, the carbon emissions of each link are calculated.

[0031] Specifically, the carbon footprint is calculated after accounting for carbon emissions in each link of the life cycle, including: The data quality assessment model is used to evaluate the data quality of carbon emissions in each link.

[0032] like Figure 2 As shown, the detailed technical solution of this method is as follows: Step 1: Get product information; Product information includes but is not limited to product name, product number and product model; After obtaining product information, conduct a data quality assessment on the product information. If the assessment is qualified, proceed to step 2; Step 2: Determine whether the current product has been tested; If not, go to step 3; if yes, return to step 1; Step 3: Based on the current product, add a new product carbon footprint accounting task; Step 4: Product objectives and scope definition; Specifically, confirm the accounting quantity, accounting quantity unit and base year. The base year is used as a historical reference point to compare changes in the carbon footprint of products over time. For example, it can assess the reduction in carbon emissions of a product after emission reduction measures are implemented compared to the base year. Step 5: Product life cycle modeling; First, confirm the product life cycle. Then, based on the product life cycle, select a period of time as the product's accounting life cycle. The selected time periods include: from production to delivery, from delivery to end of service life, and from production to end of service life. After selecting the accounting lifecycle, you need to upload documents to verify the accuracy and legality of the accounting. Documents can be in the form of documents, pictures, etc. After determining the product's accounting lifecycle, the data quality assessment needs to be conducted. If the assessment is qualified, proceed to step 6. Step 6: Check the data integrity to determine whether the data is complete; If complete, go to step 7; if incomplete, return to step 5; Specifically, based on the accounting life cycle, all data within the cycle is obtained, including but not limited to raw material usage data, main and by-product information, etc. After obtaining the data, it needs to be verified and formatted; Based on the factor library, the coefficients corresponding to the carbon emissions in each link of the accounting life cycle are obtained. Combined with the consumption of each link, the carbon emissions in each link of the accounting life cycle are calculated. Take the use of natural gas in the production process of aluminum battery products as an example: when maintaining the "natural gas" usage, the corresponding carbon dioxide emissions can be automatically calculated based on the filled-in natural gas consumption.

[0033] Calculation formula: Natural gas carbon dioxide emissions (tCO2e) = natural gas consumption Emission factor; Step 7: Result analysis; Using the product carbon footprint accounting model, the data type and attribute value field of carbon emissions are identified, and the carbon emissions data is traversed and judged to check whether there are null values. If null values ​​are found, the "data check" operation is triggered, and corresponding prompts or error messages are generated to remind the operator to supplement or correct the missing data; Feedback the inspection results and inform the operator of the completeness of the data filled in; Step 8: Generate product carbon footprint report; Generate a carbon footprint report based on the data type identification results and attribute value field confirmation results; The report results can use advanced data visualization components to intuitively display the statistics and distribution of the filled-in information in the form of charts and graphs, including the use of line charts, scatter plots, etc. to display the correlation between time series data or attribute values. Combined with the interactive interface design, flexible operations can be performed through the system interface to gain a deeper understanding of the detailed results generated by the carbon footprint accounting task, realize a dynamic update mechanism, and ensure the real-time display of results.

[0034] like Figure 3 As shown, detailed description Figure 2 The specific contents of step 5 are as follows: Step 5.1: Create a new product carbon footprint calculation; Step 5.2: Query the product database, accounting model database, and accounting target and scope definition database; Step 5.3: Based on the query results, fill in the process information; process information includes product information, accounting model information, and target and scope definition information; Step 5.4: Match product information based on product information, match accounting model information based on accounting model information, and match target and scope definition information based on target and scope definition information; Step 5.5: Perform data verification based on the matching information and conduct data quality assessment on the verification results; Step 6: Check the data integrity of the evaluation results; Step 7: Result analysis; Step 8: Generate product carbon footprint report.

[0035] In this embodiment, the model uses a data integration engine to store various information generated during the carbon footprint calculation process in a database, including but not limited to process data, attribute value field entries, and data verification results. The system utilizes advanced data visualization components to intuitively display the statistics and distribution of this information in charts and graphs. This includes the use of line charts and scatter plots to illustrate the correlation between time series data or attribute values. Combined with an interactive interface design, users can flexibly operate within the system interface to gain a deeper understanding of the detailed results generated by the carbon footprint calculation task. A dynamic update mechanism is implemented to ensure real-time display of results, ensuring the system is responsive at all times.

[0036] like Figure 4 As shown, this disclosure also proposes a process for outputting and packaging the report separately, as follows: Step 1: Enter the carbon footprint accounting document information; Step 2: Query accounting information; Step 3: Based on step 2, query product and model information; Step 4: Based on step 2, query the accounting table information; Step 5: Based on steps 2, 3, and 4, assemble the mission report information and fill in the report template; Step 6: Based on steps 2, 3, and 4, assemble the accounting inventory information and fill in the inventory template; Step 7: Create a credential compression package: Step 8: Update the report record.

[0037] In this embodiment, the user selects a specific carbon footprint accounting task on the front-end interface and executes the "Generate Report" action. The system detects the user's triggering action through front-end and back-end interaction mechanisms. The user enters a report name, and the system uses a data identification algorithm to ensure the uniqueness of the report name for subsequent report management and retrieval. Based on the selected carbon footprint accounting task, the system automatically retrieves task information, accounting model information, and accounting table information, and automatically assembles them, matching the accounting information fields with the template to ensure that the report content accurately matches the task data. The report generation process covers various content formats, including text, charts, and data tables. Using an automated generation algorithm, the system embeds the task data into the template according to the structure of the carbon footprint accounting template, creating a complete carbon footprint report. This process involves multiple steps, including document processing and data entry. The generated carbon footprint report is formatted and stored in a system-specified report library. Users can also flexibly customize the exported report template according to their actual needs.

[0038] The above-mentioned graphical method is used to realize carbon footprint data modeling, and supports automatic or manual data collection and accounting. At the same time, the mass balance method is used to verify the model data after modeling, which reduces the complexity of product carbon footprint calculation, improves applicability, and lowers the threshold for market promotion.

[0040] Specifically, the life cycle module is used to determine the life cycle of the target product, including: The life cycle module is used to select target products; Obtain product information of target products; Determine the life cycle of the target product based on product information.

[0041] Specifically, the carbon emissions module is used to calculate the carbon emissions of each link in the carbon footprint accounting life cycle based on the factor library, including: The carbon emission module is used to obtain the emission coefficient corresponding to the carbon emission of each link through the factor library; Obtain the consumption of target products in each link; Based on the emission coefficient and consumption, the carbon emissions of each link are calculated.

[0042] Specifically, the system further includes: The evaluation module is used to use the data quality evaluation model to evaluate the data quality of carbon emissions in each link.
