Decarbonization became one of the important issues for tackling global warming in Japan. Both housing and transport sectors should reduce energy consumptions particularly in existing residential areas cooperation between them. However, national policies only indicate sector-specific initiatives, and it is not clear how to develop coordinated measures in both sectors. This study examines the environmental performance of each sector and the effectiveness of the project by introducing environmental measures using EV, energy conservation and renewable energy, to decarbonize in existing residential areas. As a result, introduction of coordinated measures is effective in terms of environmental and business feasibility.
