Abstract
In order to prevent air pollution and to reduce CO2 emissions, Electric Vehicles (EVs) that do not emit exhaust gas while driving are beginning to spread worldwide. But considering exhaust emissions from power plants, exhaust gas dose not be said to be zero. In this paper, the author focus on CO2 emissions from power plants, evaluate the CO2 emissions from EVs and discuss the surrounding conditions of EVs around 2030 for reducing more CO2 emissions than hybrid vehicles.
