HLCE (Human Life Cycle Emission) , a life cycle assessment (LCA) methodology to evaluate greenhouse effect gases emission per capita and database of unit factors are developed and applied to several local cases in Japan. Futureprojection scenario to the year 2050 on social, economical, technological and energy supply situations are described and using HLCE, CO2 and greenhouse effect gases emissions and reduction potentials are estimated. As a part of this study a data base of environmental load unit factor table using Input/Output Table is developed. Emission inventory database of greenhouse effect gases by emission source and energy type splitting to municipal areas is prepared and opened.
