摘要
碳达峰、碳中和是国家实施的重要战略决策,而发展电动汽车是实现低碳的举措之一。针对现有电动汽车碳排放评估片面和不准确,以及未对碳排放数据的共性进行归纳分类问题,提出一种基于全生命周期的电动汽车碳排放核算模型和碳排放数据分类方法,并以理想L8为案例计算了其生命周期各阶段的碳排放量。研究结果表明,在电动汽车的生命周期的四个阶段中,汽车使用阶段的碳排放量占比最大,约为60.51%,其次是制造阶段、原材料获取阶段和报废回收阶段。该模型可以细化碳排放分析,提高降碳方案的精确性,且在实际案例分析中具有重要作用,有助于汽车行业开展碳足迹核算研究。
Carbon peaking and carbon neutrality are important strategic decisions implemented by the state,and the development of electric vehicles is one of the initiatives to realize low carbon.Aiming at the problems of one-sided and inaccurate carbon emission assessment of existing electric vehicles,as well as the failure to generalize and classify the commonalities of carbon emission data,this paper proposes a carbon emission accounting model for electric vehicles based on the full life cycle and a classification method for carbon emission data,and calculates the carbon emissions of the Ideal L8 at each stage of its life cycle,using the Ideal L8 as a case study.According to the findings,among the four phases of an electric vehicle's life cycle,the stage during which the vehicle is used has the highest percentage of carbon emissions(60.51%),followed by the stages of manufacturing,acquiring raw materials,and recycling at the end of the vehicle's life.The model plays a significant role in the actual case analysis,which aids the automobile industry in conducting carbon footprint accounting research.It can also increase the accuracy of the carbon reduction program and refine the carbon emission analysis.
