Analysis of Carbon Emission Assessment of Automotive Products Based on Life Cycle Assessment and Suggestions for Low Carbon Development

The “Double Carbon” goal puts forward new requirements for the development of the automobile industry. Carbon neutralization in the automobile industry is a systematic project, which requires not only technological breakthroughs in the industry itself, but also carbon reduction in collaboration with other relevant industries. Evaluating the carbon emission level of automobile products with different technology routes has become a research hotspot under the existing technology level and energy structure. Based on the product life cycle assessment, a carbon emission model is built and several comparable models of the mainstream technology routes are selected so as to evaluate their carbon emission throughout the life cycle objectively. The research results show that, Battery Electric Vehicle (BEV) is one of the most important technology routes for the low-carbon development of automobile products at present and in the future. Finally, suggestions for carbon reduction in the life cycle of automobile products are put forward such as developing energy-saving technology of traditional energy vehicles, promoting low-carbon development in all aspects of power batteries, expanding the proportion of clean energy applied in vehicles, improving the green level of vehicle materials, and promoting green low-carbon transformation of production and manufacturing.
