DEVELOPMENT OF AN EVALUATION FRAMEWORK FOR GHG EMISSIONS REDUCTION POLICY SCENARIOS ON WOOD RESOURCE UTILIZATION

Abstract

An evaluation framework for policy scenarios related to wood resource flow under long-term social change in Japan was developed. Then, change of wood resource flow and life-cycle CO₂ emissions reduction effects in residential, paper and wood energy sectors until 2050 were evaluated for various policy scenarios such as housing service life extension, wooden house increase or decrease, enhancement of recycled paper usage and bio-ethanol production. In the case of housing service life extension and bio-ethanol production policy scenarios, CO₂ emissions reduction effects were estimated to increase in both the residential and wood energy sectors and the amount of CO₂ emissions reduction from no policy scenario in 2050 reached nearly 4% of domestic CO₂ emissions in 1990.
