Abstract:Taking China’s transportation industry as the research object, this article uses respectively the “bottom-up” and “top-down” methods to estimate the carbon emission level of China’s transportation industry in four scenarios in 2050. The results show that transportation structure adjustment and optimization, large-scale electric trucks, and energy structure optimization can effectively reduce carbon emissions of China’s transportation industry by 2050. It is found that transportation structure adjustment and optimization shows the best marginal emission reduction effect, with a rapid reduction effect at first and a gradual slow down trend, whereas the contribution rate of large-scale electric trucks to carbon emission reduction shows a slow effect at first and then gradually increasing trend. Therefore, to achieve the carbon emission reduction targets of China’s transport industry under the carbon neutrality strategy, China needs to accelerate the pace of energy structure optimization, continuously optimize the transportation structure, promote the application of electric truck technology and popularize road electrification.
