In order to achieve the national target of carbon peak and carbon neutral，the automobile industry has done a solid job in carbon emission reduction and comprehensively promoted green and low-carbon transformation. Based on the life-cycle carbon emission accounting method for automobiles，the life-cycle carbon emission at the level of single vehicle was accounted，a low-carbon transformation path for the automobile industry was proposed，the relevant emission reduction potential was quantified and the suggestions for China’s automobile industry to achieve green and low-carbon high-quality development were put forward：to establish and improve the standards and data management system，to promote the R&D and application of low-carbon materials and low-carbon technologies，and to accelerate the promotion of new consumption patterns in the automotive industry. The relevant research results could further support the formulation of national carbon emission policies，promote the R&D and application of low-carbon technologies in enterprises，guide consumers to green and low-carbon consumption，and lead the automotive industry to move toward the vision of whole-life carbon neutrality.
