Description

TECHNICAL FIELD

[0001] The application relates to the technical field of carbon accounting methods, in particular to a carbon accounting method based on a green supply chain carbon management platform. BACKGROUND

[0002] Carbon footprint accounting is mainly based on the principle of life cycle assessment (LCA), which quantifies the environmental impact by identifying the greenhouse gas emissions generated in the whole process of product from raw material acquisition, production and manufacturing, distribution and transportation, use to waste recycling.

[0003] Traditional accounting methods often treat each link of the supply chain separately, lack effective use of upstream carbon emission data and reasonable transmission mechanism to downstream products, resulting in large deviation of accounting results, making it difficult to provide accurate emission reduction decision support for enterprises.

[0004] Existing solutions mainly focus on reducing carbon emissions through technical improvement, optimizing production process and selecting low-carbon raw materials. However, these solutions usually face problems such as high cost, high technical difficulty and long production cycle, which leads to great economic pressure for enterprises in achieving low-carbon goals. Therefore, developing a method that can accurately assess the upstream carbon footprint of the supply chain is of great significance to promote the low-carbon transformation of enterprises. This method not only helps enterprises reduce carbon emissions, but also improves the market competitiveness and sustainable development ability of enterprises.

[0005] The existing technology has the following disadvantages when performing carbon footprint accounting: Data island phenomenon is serious, different data collection systems and measurement standards are used in each link of mining, metallurgy, chemical industry, building materials, etc. Key information such as energy consumption, material consumption and emission factors is scattered in ERP and MES, lacking unified data semantics and interface standards, resulting in that downstream cannot directly obtain real carbon data from upstream.

[0006] Factor update lags behind, the existing LCA database in China mainly uses regional average and annual static data, which cannot timely reflect the carbon intensity fluctuations caused by technological transformation, energy structure changes or process route adjustments, and downstream enterprises can only use the average of the past, resulting in a large deviation between the accounting results and the real emissions.
