Description

Technical Field

[0001] This application relates to the field of smart home appliance technology, and in particular to a method and system for calculating the carbon footprint of home appliances. Background Technology

[0002] Against the backdrop of escalating global climate change and frequent environmental problems, achieving carbon peaking and carbon neutrality has become a major development goal, and energy conservation and emission reduction have become key guidelines for promoting the green transformation of various industries. In the home appliance sector, refrigerators and washing machines, as necessities of daily life, are used frequently and consume a lot of energy. Their carbon emissions have a significant impact on energy consumption and the environment of households and society as a whole.

[0003] To meet these needs, a series of studies and practices on product carbon emission accounting have been conducted. Some studies focus on establishing universal product carbon footprint accounting models, which calculate carbon emissions by collecting data on energy consumption and raw material usage at each stage of the product's entire life cycle, based on specific accounting standards and methods. Other companies or institutions have developed specialized carbon emission accounting software. This software encapsulates the accounting model into an informational framework, allowing users to obtain the product's carbon emission results simply by inputting relevant data. Furthermore, some industry organizations have developed carbon emission accounting guidelines for refrigerators and washing machines, providing manufacturers and third-party organizations with a unified accounting framework and process guidance.

[0004] However, general carbon emission accounting models are often too complex. When dealing with specific products like refrigerators and washing machines, they require a large amount of complex and specialized data, which not only increases the difficulty and workload of the calculation but also easily leads to biased results due to inaccurate data. While dedicated carbon emission accounting software simplifies the operation to some extent, its functions are relatively limited and lack specific optimization for the characteristics of refrigerators and washing machines, making it impossible to quickly and accurately calculate their carbon emissions. Industry accounting guidelines focus more on theoretical frameworks and process specifications. In practical applications, due to the lack of effective tools, manufacturers and consumers still find it difficult to conveniently conduct carbon emission accounting. Summary of the Invention

[0018] Figure 1 This is a flowchart illustrating the carbon footprint calculation method for household appliances in this application. Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0020] Because some technologies lack fast and convenient tools for calculating the carbon footprint of home appliances, this application provides a method and system for calculating the carbon footprint of home appliances to address this technical problem. The method and system for calculating the carbon footprint of home appliances are described below: like Figure 1 The diagram shown is a flowchart of the carbon footprint calculation method for home appliances in this application.

[0021] The first aspect of this application provides a method for calculating the carbon footprint of household appliances, including the following steps: S100: Establish a carbon accounting process modeling information database; the carbon accounting process modeling information database is used to store BOM information, home appliance product information, process information, energy information, waste information, transportation information, product usage information, and recycling information; the carbon accounting process includes: raw material acquisition stage, production and manufacturing stage, transportation stage, usage stage, and recycling stage.

[0022] The BOM (Bill of Materials) information includes: product material name, raw material, material weight, transportation method, distance, and unit of measurement for transporting the material to the manufacturer; the home appliance product information includes: product category and product name; the process information includes: process flow name, process name, and process product name; the energy information includes: type of energy used in the product manufacturing process, energy consumption, and unit of measurement; the waste information includes: waste category and waste name; the transportation information includes: transportation method and transportation distance; the product usage information includes: product energy efficiency rating, usage frequency, and power consumption; and the recycling information includes: recycling method and information on recycled materials.

[0023] Specifically, when calculating the carbon footprint of home appliances, the carbon accounting process is initiated first. The carbon accounting process is divided into five stages based on the LCA (Life Cycle Assessment): raw material acquisition, production and manufacturing, transportation, use, and recycling. Each life cycle stage is decoupled from the others and carbon emissions are calculated independently, which greatly improves the versatility of the carbon accounting model.

[0024] This includes: BOM (Bill of Materials) information collection and initialization to provide basic information for configuring the activity dataset of the raw material acquisition stage; home appliance product information collection and initialization to provide basic information for configuring the activity dataset of the production and manufacturing stage; process information collection and initialization to provide basic information for configuring the activity dataset of the production and manufacturing stage; energy information collection and initialization to provide basic information for configuring the activity dataset of the production and manufacturing stage; waste information collection and initialization to provide basic information for configuring the activity dataset of the production and manufacturing stage; transportation information collection and initialization to provide basic information for configuring the activity datasets of the raw material acquisition and transportation stages; product usage information collection and initialization to provide basic information for configuring the activity dataset of the usage stage; and recycling and processing information collection and initialization to provide basic information for configuring the activity dataset of the recycling stage.

[0025] S200: Establish a carbon emission factor library; the carbon emission factor library is used to store carbon emission factors for each stage of the carbon accounting process; the carbon emission factors for each stage of the carbon accounting process are configured by initializing the carbon emission factors in the carbon emission factor library.

[0026] For example, the carbon emission factor is a core tool for quantifying carbon emissions, referring to the amount of greenhouse gas emissions generated per unit of production or consumption activity. Specifically, stage carbon emissions = stage activity dataset × stage carbon emission factor.

[0027] S300: Based on the carbon accounting process modeling information library and the carbon emission factor library, establish a product carbon accounting model library; the product carbon accounting model library stores several product carbon accounting models; combine the basic information of the carbon accounting process modeling information library and the carbon emission factors of the carbon emission factor library to construct carbon accounting models for refrigerator and washing machine home appliances, and form a carbon accounting model library for refrigerator and washing machine home appliances.

[0028] The step of establishing a product carbon accounting model based on the carbon accounting process modeling information database and the carbon emission factor database includes the following sub-steps: S310: Determine the system boundary of carbon emissions and map it into the carbon accounting process.

[0029] S320: Based on the carbon accounting process modeling information database and the carbon emission factor database, determine the activity datasets and carbon emission factors for each stage of the carbon accounting process, and generate the corresponding product carbon accounting model. The activity datasets correspond to the carbon accounting process modeling information in the carbon accounting process modeling information database.

[0030] Specifically, the product carbon accounting model is configured and generated according to the requirements of life cycle assessment. It is constructed through the following process: The system boundary of carbon emissions is determined and abstracted and mapped to all or part of the carbon accounting process in the raw material acquisition, manufacturing, transportation, use, and recycling stages. Activity datasets and carbon emission factors are configured for each stage of the carbon accounting process to generate corresponding product carbon accounting models. Based on the product carbon accounting models, customized carbon accounting models are formed, thus creating a standard product carbon accounting model library and a customized carbon accounting model library.

[0031] S400: Determine the corresponding carbon accounting model for the product based on the type of home appliance to be calculated.

[0032] The step of determining the corresponding product carbon accounting model based on the type of home appliance to be calculated includes the following sub-steps: S410: Based on the type of home appliance to be calculated, call the corresponding product carbon accounting model in the product carbon accounting model library and generate a carbon accounting data source list; the carbon accounting data source list includes: BOM information corresponding to the activity dataset in the raw material acquisition stage, as well as the transportation method and transportation distance information of the raw material transportation; process steps, usage of various energy sources, and waste information corresponding to the activity dataset in the production and manufacturing stage; transportation method and transportation distance information corresponding to the activity dataset in the transportation stage; energy efficiency level, usage frequency, and power consumption information corresponding to the activity dataset in the usage stage; recycling treatment method corresponding to the activity dataset in the recycling stage; and carbon emission factor information selected for each carbon accounting process step.

[0033] S420: Perform the carbon accounting source data entry operation according to the carbon accounting data source list.

[0034] Specifically, the process involves selecting a home appliance category, calling the corresponding home appliance carbon accounting model from the product carbon accounting model library, and generating a carbon accounting data source list. The carbon accounting source data is then entered based on this list. This data entry can be done manually or by importing data from the company's information database, allowing for multiple methods of data entry.

[0035] S500: Calculate carbon emission data using the product carbon accounting model and generate a carbon emission report.

[0036] The step of calculating carbon emission data using the product carbon accounting model includes the following sub-steps: S510: Calculate carbon emission data asynchronously using source data and product carbon accounting models corresponding to each stage of the home appliance product's lifecycle. The source data is used as calculation parameters, and the carbon accounting models corresponding to each stage of the home appliance product's lifecycle are called to calculate carbon emission data asynchronously.

[0037] The step of generating a carbon emission report includes the following sub-steps: S520: Store the carbon accounting results for each stage of the entire lifecycle of home appliances; S530: Merge the carbon accounting results to form a carbon emission report. The carbon accounting results for each stage of the entire lifecycle of home appliances are stored in stages, and then merged and summarized to form a carbon emission report, making it easier for companies to view the carbon accounting results for each stage.

[0038] The carbon footprint calculation method for home appliances provided in this application fully considers the carbon emission sources at each stage of the entire life cycle of home appliances, highly abstracts the carbon accounting process links, and decouples them from each other, ensuring the independence of carbon emission accounting between each stage, greatly improving the universality of the carbon accounting model, and improving the precision and accuracy of the accounting; at the same time, only the accounting source data needs to be entered and the calculation rule engine is called to automatically realize carbon accounting and generate carbon emission reports.

[0039] The method further includes the following steps: S600: Obtain the version information of the product carbon accounting model; S700: If the version information is inconsistent with the target version, use the version update function to update the version of the product carbon accounting model to the target version. After configuring and generating the product carbon accounting model, model release and version management are also required, specifically including: releasing the configured and generated product carbon accounting model; after the released product carbon accounting model is reviewed by home appliance carbon accounting experts, it is entered into the product carbon accounting model library and is regularly changed and optimized in accordance with national policies.

[0040] This application provides a method for calculating the carbon footprint of home appliances. Based on factors such as the type of home appliance, manufacturing process, energy efficiency rating, usage frequency, power consumption, and recycling method, it can quickly and accurately calculate the carbon emissions generated by the home appliance throughout its entire life cycle, providing data support for enterprises to develop low-carbon home appliances. It fully considers the carbon emission sources at each stage of the home appliance's life cycle, establishes a carbon accounting process, and decouples these processes to ensure the independence of carbon emission accounting between each stage. This greatly improves the versatility of the carbon accounting model and enhances the precision and accuracy of the calculation. Furthermore, by simply inputting the accounting source data and calling the calculation rule engine, carbon accounting can be automatically performed, generating a product carbon footprint report (carbon emission report).
