摘要：

In sustainable society, leasing and rental attract attention. The reason is that the used products can be recovered about 100% by leasing or rental, and it may promote recycling and reuse and the environmental load may decrease. However, there are few examples quantitatively evaluated about the reduction effect of the environmental load by leasing personal computers. The aim of this study is evaluating the reduction effect of the environmental load by leasing PC. The LCA method used by this research was Life-cycle impact assessment Method based on Endpoint modeling (LIME). LIME can compute environmental load as external cost given to society. We evaluated quantitatively about the following three effects. By the increase in the recovery rate of PC, environmental load is reduced about 20%, and the reduction effect of external cost was calculated with about I billion yen. By choosing not a desktop PC but a notebook PC, environmental load is reduced about 60%, and the reduction effect of external cost was calculated with about 2.4 billion yen. By leasing PC again, environmental load is reduced about 30%, and the reduction effect of external cost was calculated with about 1.7 billion yen.
