Abstract
It is presumed that the estimation of the urban renovation by strategic urban environmental improvement policies on districts and cities that precedes the estimation of individual products and structures will be questioned, so that environmental emissions estimation methods to lead such policies and supporting tools will be needed. This paper supplies a basic scheme of estimation system for life cycle environmental emissions caused by different planning scenarios and environmental improvement methods on the urban renovation process as its prototype system for preliminary simulation analysis. The system of high utility for mainly urban planners is developed to enable simple estimation on urban renovation projects. It is composed of four basic sub-systems, and life cycle estimation processes consist of seven stages from material production to demolition. As life cycle estimation indexes, CO2 emissions and solid wastes, etc. that are most important as global andregional problems are taken up. The ultimate purpose of efforts in the future is to develop the system that be capable of making specific proposals for sustainable urban redevelopment projects and that can be applied to preparation of guidelines on urban environmental master plans and strategic environmental assessment, etc. inmunicipalities.
