CARBON FOOTPRINT ACCOUNTING AND EVALUATION OF AUTOMOTIVE AIR CONDITIONING FILTERS BASED ON LIFE CYCLE ASSESSMENT (LCA)
Keywords:
Life Cycle Assessment, Automotive air conditioning filter, Carbon footprintAbstract
Driven by the "dual carbon" goals to promote the green transformation of the automotive industry, the full-life-cycle carbon footprint of automotive components has become a core focus of the industry's low-carbon development. This study takes automotive air conditioning filters as the research object. Based on the Life Cycle Assessment (LCA) methodology, it defines the carbon footprint accounting boundary covering the "raw material acquisition - production - transportation - end-of-life" process, constructs a carbon footprint calculation model, and conducts full-life-cycle carbon footprint accounting for three typical automotive air conditioning filters. The results show that the raw material acquisition stage is the main contributor to the carbon footprint of automotive air conditioning filters, accounting for more than 60% of the total. Furthermore, approaches to reduce the product's carbon footprint are proposed, including material substitution, process optimization, energy and auxiliary material upgrading, and waste recycling. The research results provide a theoretical basis and data support for the low-carbon design, production optimization of automotive air conditioning filters, and carbon management of the automotive industry chain.References
