Economic and environmental impacts on the portfolio of clean energy vehicles in Japan

Abstract

The introduction of clean energy vehicles (CEVs) is one of the meas- ures expected to be employed against global warming. Because the structures of CEV parts are different from those of gasoline vehicles, the popularization of each CEV type has two different types of impacts: economic and environmental. Therefore, it is necessary to consider the optimal mix of CEVs before deciding upon a policy for the introduction of CEVs. However, most conventional studies do not consider the economic effects on industries. This paper proposes a new optimization model considering the production-induced effects as well as envi- ronmental impacts. The model is applied to estimate the impacts on the portfolio of CEVs in 2030 in Japan.
