[0002] With the increasing global awareness of environmental protection, reducing carbon emissions and achieving low-carbon production have become the common goals pursued by all industries. In the automotive manufacturing industry, aluminum alloy sheets, as important raw materials, the carbon emissions during their production process cannot be ignored. Traditional carbon footprint calculation methods often rely on manual data collection and processing, which is not only inefficient but also prone to errors. In addition, since the production process of automotive aluminum alloy sheets involves multiple links, including raw material procurement, production processing, transportation, use and waste treatment, etc., carbon emissions may occur in each link. Therefore, to comprehensively and accurately calculate its carbon footprint, various factors throughout the entire life cycle need to be considered. Most of the existing carbon footprint calculation systems can only estimate the carbon emissions for a single link or a specific stage, and cannot achieve the precise calculation of the carbon footprint of automotive aluminum alloy sheets throughout the life cycle. At the same time, there are also many deficiencies in these systems in terms of data collection, processing and analysis, such as incomplete data collection, inaccurate data processing, and unintuitive analysis results. Summary of the Invention
