基于生命周期理论的汽车产品碳排放评价研究及低碳发展建议

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

“双碳”目标对汽车产业发展提出新要求,汽车产业碳中和是一项系统工程,不仅需要行业自身技术突破,还需要与其它相关行业协同降碳。在现有技术水平和能源结构下,评价不同技术路线汽车产品碳排放水平已成为研究热点。基于产品生命周期理论构建碳排放模型,选取主流技术路线下的可比车型对其全生命周期的碳排放情况进行客观评价,研究结果显示:当前及未来,纯电动汽车都是汽车低碳发展最重要的技术路线之一。最后,从发展传统能源汽车节能技术、推进动力电池各环节低碳化、扩大车用清洁能源使用比例、提升车用材料绿色化水平、推动生产制造绿色低碳转型方面提出汽车产品生命周期减碳建议。

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 lowcarbon transformation of production and manufacturing.
