Abstract

This paper aims to evaluate environmental impacts from resource dissipation to global warming in civil infrastructure systems as an basis of discussion on sustainable industrial transformation for this industrial society.Civil infrastructure system give considerable impacts both directly and indirectly through various product chains and supply of related societal services.From this aspects, first, the content of environmental impacts were divided into several categories according to its repercussive characteristics.Second, specific environmental impacts were analyzed using life cycle inventory approaches including input-output analysis.As a result, the followings were examined: 1) various product chains were observed with relation to release of carbon dioxide and industrial waste, and steel consumption due to construction activities; 2) machinery and utility-derived impacts were recognized to some extent as well as cumulative stock impacts of the infrastructure bodies; 3) considerable environmental impacts due to societal services supported by civil infrastructure indicated the necessity of further discussion on the allocation of responsibility for reducing the impacts.
