Based on a comparison of life-cycle carbon and pollution emissions of fuel-fired light-duty vehicles and new energy vehicles and an analysis of the influencing factors

Abstract

Using the GREET model and the WTW system, compare and analyse the carbon emissions of fuel-light vehicles (E10, liquefied natural gas) and new energy vehicles (pure electric vehicles, hybrid electric vehicles, plug-in hybrid electric vehicles, liquefied hydrogen energy) during the entire life cycle of automobiles and pollutant emissions and compare the carbon emissions of plug-in hybrid vehicles under different power structures. The conclusions of the emissions of the two models, the number of emission factors, the contribution of various links of the two models, upstream emissions, vehicle life, light materials, and power structure are drawn, and relevant suggestions are given based on the conclusions.
