As global environmental issues are attracting attention, EVs aregenerally considered to play a major role as a zero carbon solution becausethey do not emit carbon dioxide when they run.However, the environmental impact of EVs cannot be ignored from thestandpoint of the electricity they use when driving, and this point has alsobeen attracting attention in recent years. In other words, the use ofelectricity supplied by fossil fuel power generation, as typified by coal-firedpower generation, is not only ineffective in terms of environmental impact,but may even have a negative impact. Therefore, it is necessary to fullyconsider whether EVs can make a significant contribution to environmentalmeasures when the environmental impact of EVs is considered as a whole.In this paper, we would like to compare the life cycle assessment (LCA)of EVs and gasoline-powered vehicles to comprehensively determine theirenvironmental advantages.In other words, the purpose is to discuss the overall environmentaladvantages of EVs and gasoline-powered vehicles by comparing theenvironmental impacts of EVs and gasoline-powered vehicles in allprocesses of their sequence of flow, including procurement of rawmaterials, manufacture of parts and finished vehicles, delivery, sales, after-sales service, and disposal.
