Description
Summary:Replacing internal combustion engine vehicles with electric vehicles is the most direct pathway to decarbonize transportation. This paper investigates the environmental benefits of electric vehicle adoption in Shanghai—China’s largest regional electric vehicle market. Using vehicle registration data and well-to-wheel analysis, this paper calculates the potential emissions reductions of carbon dioxide and air pollutants for each electric vehicle model sold in Shanghai in 2018. Our results indicate that electric vehicles have been over-subsidized: The average environmental benefit was less than one-fourth of the mean subsidy received. Also, the environmental benefits were not distributed uniformly: About 80% of electric vehicle models generated less than 20% of the aggregate environmental benefits. Finally, three policy recommendations are provided to improve the environmental benefits of electric vehicle adoption.
