Description

Technical Field

[0001] This application relates to the field of carbon footprint accounting technology, and in particular to a method and apparatus for calculating the carbon footprint of a product. Background Technology

[0002] With the increasing prominence of climate change and ever-increasing environmental protection requirements, a low-carbon economy has become an important direction for economic and social development. As a fundamental industry for energy supply, the power sector has long relied primarily on fossil fuel consumption, resulting in a high proportion of its carbon emissions in the overall carbon emission structure. Power equipment, as a crucial component of the power system, generates greenhouse gas emissions to varying degrees throughout its entire lifecycle, including raw material acquisition, manufacturing, transportation, use, and decommissioning. Its carbon emission levels significantly impact the power sector's low-carbon transformation. Therefore, conducting scientific and accurate carbon footprint accounting for power equipment is of great importance for promoting the green development of the power industry.

[0003] Currently, there are still many shortcomings in the carbon footprint accounting methods for power equipment. On the one hand, existing carbon emission accounting methods mostly focus on the power generation process or certain life cycle stages of the power system, lacking a systematic accounting of carbon emissions from the transmission link and the entire life cycle of specific power equipment. On the other hand, when applied to power equipment, especially cables and electrical equipment, existing carbon footprint accounting standards still suffer from problems such as unclear definitions of functional units and baseline flows, incomplete system boundary delineation, insufficient detail in accounting content, and poor comparability of accounting results. In addition, existing evaluation systems often emphasize the product manufacturing or usage stages, failing to fully cover the entire life cycle chain of "raw material acquisition—raw material transportation—manufacturing—product transportation—product use—retirement and recycling," resulting in insufficient data connection and coordination between different life cycle stages, making it difficult to comprehensively reflect the true carbon emission level of power equipment.

[0004] Existing technologies, for example, involve mapping the carbon footprint calculation path of power equipment, determining system boundaries based on a lifecycle flowchart, and establishing a multi-layered basic calculation model to calculate and summarize carbon emissions at each stage of the power equipment's entire lifecycle. Through system boundary confirmation, multi-source data integration, and accounting model construction, carbon emissions from transformer products at stages such as raw material acquisition, transportation, production, use, and decommissioning and recycling are quantified. While these technical solutions have promoted the development of carbon footprint accounting methods for power equipment to some extent, they still have the following shortcomings.

[0005] First, existing technologies generally adopt a unified, universal accounting framework, failing to differentiate between the variations in production processes of power equipment. In particular, they lack differentiated system boundary delineation rules for equipment directly producing raw materials and equipment assembling components. This leads to the easy omission of key aspects such as component production and inter-factory transportation, resulting in incomplete lifecycle coverage. Second, activity level data collection relies heavily on manual entry, lacking standardized data collection templates and automatic verification mechanisms. Data gaps, format errors, or numerical anomalies are difficult to detect promptly, and upstream component production data is hard to obtain, compromising data quality. Third, emission factor matching primarily relies on manual queries or the application of general databases, lacking a dedicated factor system tailored to the characteristics of power equipment. Insufficient factor adaptability and timeliness affect the accuracy of the accounting results. Finally, the existing accounting process has a low degree of automation, heavily relying on manual operation. This reduces efficiency, increases the risk of calculation errors, and lacks quantitative assessment of the uncertainty of the results, making it difficult to effectively verify the reliability of the results.

[0033] This application reduces the difficulty and time of accounting by clearly defining differentiated accounting boundaries, standardizing data collection templates, and automating factor matching and accounting, while improving the quality of activity-level data and the accuracy of accounting results, thereby achieving efficient and accurate accounting of the carbon footprint of power equipment throughout its entire life cycle.

[0034] The following describes the specific implementation process of the product carbon footprint calculation method provided in this application embodiment, using a server as the execution subject as an example.

[0035] Figure 1 This is a schematic diagram of the first process of the product carbon footprint accounting method provided in this embodiment of the invention, as shown below. Figure 1 As shown, in one embodiment of the present invention, the product carbon footprint accounting method of the present invention includes: S101: Establish a full life cycle carbon footprint accounting model for the product to be accounted for based on the production process characteristics of the product to be accounted for; S102: Collect the activity level data of the product to be accounted for at each stage of its entire life cycle according to the pre-generated activity level data collection template; S103: Perform carbon footprint accounting on the product to be accounted for based on the activity level data, the full life cycle carbon footprint accounting model, and the pre-built factor database.

[0036] from Figure 1 As shown in the flowchart, the product carbon footprint accounting method provided in this application establishes a full life cycle carbon footprint accounting model for the product to be accounted for based on the production process characteristics of the product; collects activity level data of the product to be accounted for at each stage of its full life cycle according to a pre-generated activity level data collection template; and performs carbon footprint accounting for the product to be accounted for based on the activity level data, the full life cycle carbon footprint accounting model, and a pre-constructed factor database. This effectively reduces the difficulty of carbon footprint accounting and shortens the accounting time, while improving the completeness and accuracy of activity level data, thereby achieving efficient and accurate accounting of the full life cycle carbon footprint of power equipment.

[0037] Each step is explained in detail below.

[0038] S101: Establish a full life cycle carbon footprint accounting model for the product to be accounted for based on the production process characteristics of the product to be accounted for; Specifically, the server first establishes a full lifecycle carbon footprint accounting model for the product based on the characteristics of its production processes. The server acquires information about the product's production type, identifying whether the product is produced directly from raw materials or assembled from components, and constructs a lifecycle accounting structure that matches the characteristics of that production process. By analyzing the product's production process, the server determines the various carbon emission activities involved in the product's lifecycle and incorporates these activities into a unified lifecycle framework, thus forming a full lifecycle carbon footprint accounting model for subsequent carbon footprint calculations, providing a structured foundation for the phased calculation of carbon emissions.

[0039] Figure 2 This is a schematic diagram of the second process of the product carbon footprint accounting method provided in the embodiments of the present invention, as shown below. Figure 2 As shown, in one embodiment of the present invention, S101 includes: S201: Determine the scope of carbon footprint accounting based on the characteristics of the production process; Specifically, after receiving the basic information of the product to be accounted for, the server determines the scope of carbon footprint accounting based on the characteristics of the product's production processes. The server analyzes the types of processes involved in the product's production, identifying whether the product is formed through direct processing of raw materials or through the assembly of multiple components. It also systematically reviews carbon emission activities in conjunction with the product's production, transportation, use, and decommissioning processes. By identifying the characteristics of the production processes, the server can determine the lifecycle stages that need to be included in the carbon footprint accounting process, thus clarifying the scope of stages that should be covered in the product's carbon footprint accounting and avoiding omissions or double counting of carbon emission stages due to an unreasonable accounting scope.

[0040] In one embodiment, considering the complex manufacturing processes and significant differences in types of power equipment products, the carbon footprint accounting scope of power equipment is determined based on the characteristics of the product manufacturing processes. When defining the accounting scope, the server first identifies the product's manufacturing method and uses this as the basis for determining the full lifecycle accounting boundary.

[0041] For power equipment produced directly from raw materials, the server defines the accounting scope as the stages of raw material acquisition, raw material transportation, product manufacturing, product transportation, product use, and recycling. Under this production method, the product is formed through the direct processing of raw materials, without involving the external assembly of independent components. Taking cement poles as an example, in the raw material acquisition stage, data on raw materials such as cement, sand, gravel, and rebar needs to be collected; in the product manufacturing stage, raw materials such as cement and sand undergo cement mixing, rebar welding, casting, centrifugation, and oxygen vaporization to form the final product. Based on the above production process, the server includes all carbon emission activities related to these processes in the accounting scope, thereby achieving complete coverage of the carbon emissions throughout the entire life cycle of this type of power equipment.

[0042] For power equipment based on component assembly, the server, in addition to the aforementioned accounting scope, further incorporates the component production and transportation stages into the accounting scope. This means the accounting scope includes raw material acquisition, raw material transportation, component production, component transportation, equipment production, equipment transportation, equipment use, and recycling / disposal. Taking transformers as an example, key components such as the core, windings, and insulators are all formed through independent production processes, and the carbon emissions generated during their production need to be accounted for as independent stages. Furthermore, after production, these components typically need to be transported across factories or regions to the equipment assembly stage; the carbon emissions generated during component transportation also need to be included in the accounting scope. By introducing the component production and transportation stages, the server effectively covers carbon emission activities at all stages of the entire lifecycle of this type of power equipment.

[0043] By defining the accounting scope for two different processes—direct raw material production and component assembly production—in the embodiments, the server can construct lifecycle accounting boundaries that match the actual production process of the product in different production scenarios. This enables comprehensive coverage of carbon emissions throughout the entire lifecycle of power equipment and avoids the problem of missing carbon emission links due to unreasonable division of accounting boundaries.

[0044] S202: Based on the aforementioned accounting scope, establish the full life cycle carbon footprint accounting model.

[0045] Specifically, the server establishes a full lifecycle carbon footprint accounting model based on this accounting scope. The server constructs an accounting framework describing the product lifecycle structure based on each lifecycle stage included in the accounting scope, and manages each lifecycle stage within a unified accounting model. This accounting model characterizes the organizational relationships and calculation logic of carbon emission activities throughout the product's entire lifecycle, providing overall structural support for subsequent carbon footprint accounting based on activity level data and carbon emission factors, enabling product carbon footprint accounting to be conducted within a complete and consistent lifecycle boundary.

[0046] Figure 3 This is a schematic diagram of the third process of the product carbon footprint accounting method provided in this embodiment of the invention, as shown below. Figure 3 As shown, in one embodiment of the present invention, S202 includes: S301: Based on the functional units of the product to be accounted for, the entire life cycle within the accounting scope is divided into multiple carbon emission accounting stages; Specifically, after determining the scope of the calculation, the server divides the entire product lifecycle into stages based on the functional units of the product to be calculated. The server first obtains the functional unit information used for the product's carbon footprint calculation and, using the functional units as a unified measurement basis, aggregates all carbon emission activities involved in the entire process from production to decommissioning. Under the constraint of functional units, the server divides different activities in the product lifecycle into stages, enabling various carbon emission activities to be compared and summarized on a unified scale, providing a clear stage structure for subsequent carbon emission calculations.

[0047] S302: Establish corresponding carbon emission calculation models for each of the aforementioned carbon emission accounting stages; Specifically, the server establishes a corresponding carbon emission calculation model for each stage of carbon emission accounting. Based on the characteristics of carbon emission activities in different stages, the server constructs calculation models to describe the carbon emission calculation logic for that stage, representing the correspondence between activity level data and carbon emission amounts. The carbon emission calculation models for each stage reflect the differences in carbon emission formation mechanisms across different life cycle stages, enabling independent calculation of carbon emissions generated by the product at different stages according to their respective calculation logic.

[0048] S303: Construct the full life cycle carbon footprint accounting model based on the carbon emission calculation model.

[0049] Specifically, the server constructs a full lifecycle carbon footprint accounting model based on the carbon emission calculation models for each stage. The server integrates these models to form a unified accounting model covering the entire product lifecycle, describing the organizational relationships and connections between carbon emission calculations at each stage throughout the product's lifecycle. Through this full lifecycle carbon footprint accounting model, the server can achieve overall accounting of the product's carbon emissions throughout its entire lifecycle while maintaining the relative independence of the calculation logic at each stage.

[0050] In one embodiment, the carbon footprint calculation formula for power equipment produced directly from raw materials is as follows: (1) In the formula: E GHG —Product carbon footprint, in kilograms of carbon dioxide equivalent (kgCO2e). E 原材料获取 —Greenhouse gas emissions during the raw material acquisition stage, expressed in kilograms of carbon dioxide equivalent (kgCO2e). E 产品生产 —Greenhouse gas emissions during the product production stage, expressed in kilograms of carbon dioxide equivalent (kgCO2e). E 产品运输 —Greenhouse gas emissions during product transportation, expressed in kilograms of carbon dioxide equivalent (kgCO2e). E 产品使用 —Greenhouse gas emissions during the product use phase, expressed in kilograms of carbon dioxide equivalent (kgCO2e). E 生命末期处置 —Greenhouse gas emissions during the end-of-life disposal stage of a product, expressed in kilograms of carbon dioxide equivalent (kgCO2e).

[0051] For power equipment manufactured based on components (parts), such as electricity meters and switchgear, the carbon footprint accounting formula is as follows: (2) In the formula: E 组件生产 — Greenhouse gas emissions during component transportation, expressed in kilograms of carbon dioxide equivalent (kgCO2e). E 组件运输 —Greenhouse gas emissions during component transportation, expressed in kilograms of carbon dioxide equivalent (kgCO2e).

[0052] During the product manufacturing stage, in addition to fully considering energy and material consumption, the production process should also take into account in-plant transportation, which usually uses diesel vehicles or electric vehicles.

[0053] During the transportation phase, transportation carbon emissions = weight of the transportation batch. Batch transport distance (Transportation carbon footprint factor) Mileage and distance correction factors) Unit component weight / shipment batch weight.

[0054] S102: Collect the activity level data of the product to be accounted for at each stage of its entire life cycle according to the pre-generated activity level data collection template; Specifically, the server collects activity level data for each stage of the product's entire lifecycle based on a pre-generated activity level data collection template. This template, pre-configured by the server, standardizes the content and format of data collected at different lifecycle stages. The server receives and organizes the activity level data generated at each stage of the product's lifecycle, including data related to production, transportation, and usage, and manages the collected data uniformly. This ensures that the activity level data corresponds to each stage in the lifecycle accounting model, providing data support for subsequent carbon footprint accounting.

[0055] In one embodiment, to obtain high-quality activity level data, the server employs a Pareto analysis method to screen procurement batches, selecting one or more batches that have a significant impact on the overall carbon footprint calculation results as key analysis targets. The server performs statistical analysis on the procurement data to identify the suppliers with the largest supply volume in each batch and conducts on-site investigations of these suppliers. Through these on-site investigations, the server can obtain activity level data closely related to the product manufacturing process, including information such as raw material procurement volume, energy consumption, product output, and transportation records, thereby improving the completeness and representativeness of the activity level data.

[0056] When a company produces multiple products simultaneously, the server determines carbon emission allocation principles based on the measurement characteristics of each product. For products with significant quality differences, the server uses product quality as the allocation basis, distributing carbon emissions generated during production according to the weight proportion of each product. For products where length is the primary unit of measurement, such as wires, the server uses product length as the allocation basis. For products where capacity is the primary performance indicator, such as transformers, the server uses product capacity as the allocation standard. By adopting clear allocation principles that match product characteristics, the server can rationally allocate carbon emissions during production to different products, thereby ensuring the accuracy and reliability of activity level data in multi-product production scenarios.

[0057] In one embodiment, the energy meter activity level data collection template includes a data collection table for the functional unit component (assembly) acquisition stage, a data collection table for the functional unit raw material acquisition stage, a data collection table for the functional unit component (assembly) transportation stage, a data collection table for the functional unit raw material transportation stage, a data collection table for the functional unit production stage, a data collection table for the functional unit transportation stage, and a data collection table for the functional unit usage stage.

[0058] The data collection tables for the functional unit component (assembly) acquisition stage are shown in Table 1; the data collection tables for the functional unit raw material acquisition stage are shown in Table 2; the data collection tables for the functional unit component (assembly) transportation stage are shown in Table 3; the data collection tables for the functional unit raw material transportation stage are shown in Table 4; the data collection tables for the functional unit production stage are shown in Table 5; the data collection tables for the functional unit transportation stage are shown in Table 6; and the data collection tables for the functional unit usage stage are shown in Table 7.

[0066] In one embodiment, the interactive terminal provides users with a function to download activity level data collection templates. Users fill in activity level data related to the product's production, transportation, and use processes according to the template requirements. During the data entry process, the server performs real-time verification processing on the entered data, including verifying the data format, detecting whether the numerical range is abnormal, and conducting a preliminary check on the integrity of the activity level data to ensure that the entered data meets the basic quality requirements for subsequent carbon footprint accounting. Only after the data verification passes can the data collection process proceed to the next processing stage.

[0067] While submitting data, users are required to upload supporting documentation corresponding to the activity level data to verify its authenticity. Supporting documentation includes purchase invoices, electricity bills, shipping documents, and other supporting documents related to the activity level data.

[0068] After completing the data entry, users can submit the activity level data collection template and supporting documents to the server via a one-click import function on the interactive interface. Upon receiving the data, the server automatically processes it, providing standardized and structured activity level data input for subsequent carbon footprint accounting processes.

[0069] S103: Perform carbon footprint accounting on the product to be accounted for based on the activity level data, the full life cycle carbon footprint accounting model, and the pre-built factor database.

[0070] Specifically, the server calculates the carbon footprint of a product based on activity level data, a full lifecycle carbon footprint accounting model, and a pre-built factor database. The server retrieves carbon emission factors from the factor database that match the activity level data and, combined with the calculation logic of each stage in the lifecycle accounting model, calculates the carbon emissions generated by the product at each stage of its lifecycle. By integrating the carbon emission calculation results from each stage, the server obtains the product's carbon footprint accounting result, thereby achieving a quantitative analysis of the product's carbon emissions throughout its entire lifecycle.

[0071] In one embodiment, the factor database is established through a combination of self-construction and external acquisition. The self-construction approach primarily focuses on researching raw materials, components, and production processes with industry-specific characteristics in the power equipment manufacturing process. This involves conducting on-site surveys of relevant manufacturing enterprises to collect basic data related to the production process, and then forming corresponding carbon emission factors based on this data. For example, for cold-rolled silicon steel used in transformer manufacturing, its carbon emission characteristics under different rolling process conditions are analyzed, and the carbon emission factors corresponding to different processes are incorporated into the factor database to improve the adaptability of the factor data to actual production conditions.

[0072] External data acquisition methods primarily include collecting publicly released data from the power and energy industries, as well as statistical data and research reports published by official departments. This data is then compiled and incorporated into the factor database, providing multi-source data support for the carbon footprint accounting of power equipment. This ensures that the factor data accurately reflects the characteristics of production and energy structure.

[0073] Figure 4 This is a schematic diagram of the fourth process of the product carbon footprint accounting method provided in this embodiment of the invention, as shown below. Figure 4 As shown, in one embodiment of the present invention, S103 includes: S401: Determine the carbon emission factor corresponding to the activity level data from the factor database; Specifically, after acquiring activity level data, the server determines the carbon emission factors corresponding to the activity level data from a pre-built factor database. The server parses the activity level data, identifies the types of raw materials, energy sources, modes of transportation, or other carbon emission-related activity categories reflected in the data, and searches the factor database for carbon emission factors matching these activity categories. In this way, the server can select corresponding carbon emission factors for different types of activity level data, providing a unified and reliable factor basis for subsequent carbon footprint accounting.

[0074] In one embodiment, after receiving the activity level data, the server performs carbon emission factor matching processing based on the completeness of the data submitted by the enterprises. The server first checks the completeness of the data submitted by the enterprises to determine whether they have information on raw material consumption and energy consumption, and selects the appropriate factor matching strategy accordingly.

[0075] When companies can provide detailed information on raw material and energy consumption during component production, the server utilizes a pre-built factor database to automatically match corresponding raw material carbon footprint factors and energy consumption carbon footprint factors based on the types of raw materials and energy sources provided. During the matching process, the server comprehensively considers factors such as raw material specifications, production process characteristics, and energy types to ensure that the matched carbon emission factors reflect actual production conditions. For example, when a company reports using a specific type of copper and provides corresponding energy consumption data, the server matches the appropriate raw material carbon emission factors and production energy consumption carbon emission factors in the factor database based on the copper specifications, corresponding production process, and energy consumption type for subsequent carbon footprint accounting.

[0076] When a company is unable to provide information on raw material or energy consumption during component production for various reasons, the server directly selects the default carbon footprint factor corresponding to that component from the factor database to ensure the integrity of the carbon footprint accounting process. This default value is determined based on industry averages, is reasonable and representative, and can maintain the availability of accounting results in the absence of detailed data.

[0077] In subsequent accounting processes, if enterprises provide supplementary information on raw material consumption or energy consumption, the server will re-execute the factor matching process based on the new data, replace the original default value with the actual carbon footprint factor, and make corresponding corrections to the carbon footprint accounting results, thereby improving the degree to which the accounting results reflect the actual production situation.

[0078] S402: Generate the carbon footprint calculation result of the product to be calculated based on the activity level data, the full life cycle carbon footprint accounting model, and the carbon emission factors.

[0079] Specifically, the server generates carbon footprint calculation results for the product to be calculated based on activity level data, a full lifecycle carbon footprint accounting model, and carbon emission factors. Following the pre-defined lifecycle structure and calculation logic in the full lifecycle carbon footprint accounting model, the server combines activity level data with corresponding carbon emission factors to calculate the carbon emissions generated by the product at each stage of its lifecycle. By integrating the carbon emission calculation results from each stage, the server obtains the carbon footprint accounting results for the product throughout its entire lifecycle, thereby achieving a quantitative characterization of the product's carbon emission level.

[0080] Figure 5 This is a schematic diagram of the fifth process of the product carbon footprint accounting method provided in this embodiment of the invention, as shown below. Figure 5 As shown, in one embodiment of the present invention, the full life cycle carbon footprint accounting model includes carbon emission calculation models for each carbon emission accounting stage; S402 includes: S501: Based on the carbon emission calculation model, the activity level data, and the corresponding carbon emission factors, calculate the carbon emissions of the product to be accounted for in each carbon emission accounting stage; Specifically, after completing the construction of the full lifecycle carbon footprint accounting model, the server uses this model as the basic structure for phased carbon emission calculations. The full lifecycle carbon footprint accounting model consists of multiple carbon emission calculation models corresponding to multiple carbon emission accounting stages. Each carbon emission calculation model describes the calculation logic of the product's carbon emissions within its corresponding lifecycle stage. Through this model structure, the server distinguishes and manages the carbon emission calculations of different lifecycle stages independently, thereby providing clear model support for phased carbon emission calculations.

[0081] When calculating specific carbon emissions, the server uses a carbon emission calculation model, combined with activity level data and corresponding carbon emission factors, to calculate the carbon emissions generated by the product at each stage of the carbon emission accounting process. For different lifecycle stages, the server calls the corresponding carbon emission calculation model, matches the relevant activity level data with the corresponding carbon emission factors, and thus obtains the stage-specific carbon emissions of the product at each stage. This staged calculation method accurately reflects the product's carbon emission contribution at different stages of its lifecycle.

[0082] S502: Generate the carbon footprint calculation result of the product to be calculated based on the carbon emissions.

[0083] Specifically, after calculating the carbon emissions for each stage of the carbon emission accounting process, the server generates the product's carbon footprint accounting results based on the obtained carbon emissions for each stage. The server then aggregates the carbon emissions from each stage to form the total carbon emissions covering the entire product lifecycle, thus obtaining the product's carbon footprint accounting results. These results characterize the overall carbon emission level generated by the product throughout its entire lifecycle, providing fundamental data support for subsequent carbon footprint analysis and applications.

[0084] In one embodiment, the greenhouse gas emissions during the raw material acquisition stage are calculated as follows:

[0098] Figure 6 This is a schematic diagram of the sixth process of the product carbon footprint accounting method provided in this embodiment of the invention, as shown below. Figure 6 As shown, in one embodiment of the present invention, the product carbon footprint accounting method of the present invention further includes: S601: Conduct an uncertainty assessment on the carbon footprint accounting results of the product to be accounted for; Specifically, after obtaining the carbon footprint calculation results of the product, the server conducts an uncertainty assessment of the results. The server comprehensively analyzes the activity level data and carbon emission factors used in the carbon footprint calculation process from the perspectives of data integrity, data consistency, and factor suitability. By checking the coverage and rationality of the activity level data, and analyzing the sources and scope of application of carbon emission factors, the server assesses the sensitivity of the carbon footprint calculation results to changes in the input data, thereby determining the stability and reliability of the carbon footprint calculation results and providing a basis for reliable judgment.

[0099] In one embodiment, to ensure the reliability of carbon footprint accounting results, the server conducts a comprehensive uncertainty assessment of the results from three aspects: activity level data integrity, activity level data accuracy, and factor uncertainty. Through this multi-dimensional assessment mechanism, the server can quantitatively analyze the stability and credibility of the accounting results, providing a reliable basis for the application of carbon footprint results.

[0100] During the activity-level data integrity assessment, the server performs consistency checks on data related to product production and distribution based on the principle of quality conservation. The server checks whether the sum of raw material quality and component quality equals the final product quality, setting an allowable error threshold of 5%. When the detection results exceed the error threshold, the server further analyzes the causes of the deviation, including data recording errors and inaccurate recording of losses during production, and guides the correction and supplementation of relevant data to ensure that the activity-level data fully reflects the actual situation of the product during production and distribution.

[0101] During the activity level data accuracy assessment process, the server uses technologies such as OCR enhanced recognition to identify key information in the voucher materials uploaded by enterprises. The identified data is then compared item by item with the data entered in the activity level data template. When inconsistencies are found, the server further verifies the data source and accuracy to ensure the authenticity and reliability of the activity level data and reduce the adverse impact of data entry errors on carbon footprint calculation results.

[0102] During the factor uncertainty assessment process, the server evaluates the quality of carbon emission factors from two dimensions: data reliability and data relevance. Data reliability includes statistical representativeness, temporal representativeness, and data source availability; data relevance includes geographical and technical representativeness. The server performs sensitivity analysis on carbon emission factors to assess the impact of factor uncertainty on carbon footprint accounting results. When it is found that a small change in a certain carbon footprint factor can cause significant fluctuations in the accounting results, the server further optimizes the data acquisition method for that factor to reduce the impact of factor uncertainty on the carbon footprint accounting results, thereby improving the overall stability and reliability of the accounting results.

[0103] S602: Generate a product carbon footprint report based on the uncertainty assessment results and the carbon footprint accounting results.

[0104] Specifically, the server generates a product carbon footprint report based on the uncertainty assessment results and carbon footprint accounting results. The server integrates the carbon footprint accounting results with the uncertainty assessment conclusions to form a report reflecting the carbon emissions throughout the product's entire life cycle. The product carbon footprint report is used to display the total carbon emissions of the product and its reliability analysis information, providing a unified data output format for the application, management, and external disclosure of product carbon footprint results.

[0105] In one embodiment, after completing the product carbon footprint accounting and related assessment processing, the server automatically generates and outputs a product carbon footprint report. Based on the carbon footprint accounting and assessment results, the server structures the report content to ensure that the report comprehensively reflects the product's carbon emissions and the accounting process throughout its entire life cycle.

[0106] When generating a product carbon footprint report, the server first organizes basic information related to carbon footprint accounting, including information on the client and the evaluator, and explains the methods used for carbon footprint assessment and the relevant standards upon which they are based. Simultaneously, the server summarizes the data sources, data descriptions, and data processing principles used in the accounting process, and, in conjunction with the product's production characteristics, provides corresponding system boundaries and product process flow diagrams to visually demonstrate the scope and objects of product carbon footprint accounting.

[0107] The server further organizes and presents the specific content of the product carbon footprint accounting in the product carbon footprint report, including the data source information used in the carbon footprint accounting process, the product's activity data at each stage of its entire life cycle, and the corresponding greenhouse gas emission inventory, and explains the carbon emission factors used. By organizing the above content, the report can clearly reflect the calculation basis and data composition of the carbon footprint accounting, and improve the traceability of the accounting process.

[0108] During report generation, the server also organizes and outputs the carbon footprint accounting results and their analysis. The server presents the final results of the product carbon footprint accounting in the report, and interprets the results in conjunction with the data quality assessment conclusions during the accounting process, thereby reflecting the reliability and stability of the carbon footprint accounting results.

[0109] By automatically generating and outputting product carbon footprint reports containing the above information, the server achieves a standardized presentation of carbon footprint accounting results, providing a unified data output format for the analysis, management, and external disclosure of product carbon emission levels.

[0110] This application provides a product carbon footprint accounting method. It establishes a full life-cycle carbon footprint accounting model for the product based on the production process characteristics of the product to be accounted for; collects activity level data of the product at each stage of its life cycle according to a pre-generated activity level data collection template; and performs carbon footprint accounting on the product based on the activity level data, the full life-cycle carbon footprint accounting model, and a pre-constructed factor database. This method effectively reduces the difficulty of carbon footprint accounting and shortens the accounting time, while improving the completeness and accuracy of activity level data, thereby achieving efficient and accurate accounting of the full life-cycle carbon footprint of power equipment.

[0111] This application establishes differentiated carbon footprint accounting boundaries for two different application scenarios: direct production of raw materials for power equipment and component assembly production. It clarifies the scope of product lifecycle accounting to avoid omissions in the accounting process. Based on this, a standardized data collection system covering the entire lifecycle is constructed, with categorized data collection templates designed for different lifecycle stages. Real-time verification rules are embedded during data collection, supporting the uploading of supporting documents and one-click import functions to improve the completeness and reliability of activity-level data. Simultaneously, a dedicated carbon emission factor database for power equipment is established, enabling automatic matching of raw material and component factors. In the absence of detailed data, default factors based on industry averages are used to ensure the continuity and completeness of the carbon footprint accounting process. Furthermore, a multi-dimensional uncertainty assessment method is introduced. Through quality conservation verification, OCR-based document verification, and sensitivity analysis, the reliability of carbon footprint accounting results is quantitatively assessed, effectively addressing issues such as ambiguous accounting boundaries, low efficiency, and insufficient accuracy in existing carbon footprint accounting processes.
