中国已经签署《巴黎协定》并做出CO2减排承诺，中国汽车工业应该为实现中国低碳化作贡献。本文从中国汽车低碳化系统构架、生命周期碳排放现状和2030年中国汽车销量预测三个角度出发，构建了汽车CO2排放预测模型，分析了中国汽车碳排放构成，进行了至2030年汽车碳排放总量预测，预测结果显示，中国汽车碳排放总量在2025—2030年达到峰值。本研究建立了汽车低碳化评价体系，并提出了中国汽车低碳化技术路线的建议。

To realize the commitment toward reducing CO2 emission made in the Paris Agreement, the automotive industry in China must lower its CO2 emission and contribute toward low carbonization. We have created a prediction model for CO2 emission from automobiles based on the architecture of low carbonization systems for automobiles, current emission situation within the automobile life cycle, and the sales prediction for 2030 in China. Using this model, the total CO2 emission of automobiles in China was predicted for 2030; we also analyzed the CO2 emission of the automobiles with respect to the total amount of CO2 emission in China. An evaluation system has also been set up for low CO2 emission from automobiles in China, and comprehensive suggestions for a low-carbon technology roadmap in China are also presented in this paper.
