Abstract： Reducing carbon emissions is one of the core tasks in addressing global climate warming. Specifically，in the transportation sector，vehicle carbon emissions have become a key control point. However，there is still a lack of simple and practical methods for calculating vehicle carbon emissions. To this end，this paper introduces the life cycle assessment （LCA） approach，using traditional internal combustion engine vehicles （ICEVs） and pure electric vehicles （PEVs） as research subjects，and selects data from the Ministry of Industry and Information Technology's 2O24 vehicle models for analysis.Based on existing domestic and international research findings，we introduce the LCA approach to construct carbon emisson models for ICEVs and PEVs. The advantage of the model includes： ① The calculation boundary is defined within the relatively dynamic usage phase of the vehicle lifecycle，fully reflecting the personalized characteristics of consumers. ② The calculation process is simple，with easily accessible data，producing reasonable results that can reflect the carbon emission diferences between different vehicle models. ③ It establishes a link between technical indicators and carbon emissions，which is conducive to unifying calculation standards. The empirical result shows： ① The carbon emissions of traditional ICEVs are approximately twice those of PEVs. ② For PEVs，the average carbon emissions from battery lifecycles account for about 12% of their total carbon footprint，while charging grid-related emissions account for about 88% . The research conclusion provides valuable references for both theoretical studies and practical applications in vehicle carbon emission calculations.
