Life Cycle Analysis of Lifetime Changes of Durable Goods: The Case of Automobile

Abstract

Referring to the recent articles by Kagawa et al.（2008, 2009）, this paper presents a methodology to estimate the effects of the automobile lifetime changes on the life cycle energy consumptions associated with automobile productions and automobile use（i.e., driving on roads）and explains about the estimation results. Finally, I mention about the importance of extending the proposed methodology and future research directions in input-output life cycle assessment.
