Abstract

In order to evaluate the environmental impact of Nagano prefecture industry, we estimated environmental impact substances in Nagano prefecture industry with an input-output table. The four items of environmental impact substances, CO₂, NO_x, SO_x and SPM, were considered. Then we executed environmental impact assessment by using LIME to evaluate total environmental impact of Nagano prefecture industry. As a result of these analyses, the characteristic of environmental impact of Nagano prefecture industry was clarified.
