Analysis on Material Stock Flow and CO₂ Emission toward the Sustainable Society - Focusing on Municipalities in Hokuriku Region -

Abstract

 It is necessary to understand amount of the future CO₂ emission and material stock flow in order to attain a sustainable society. In this study, we estimated future CO₂ emissions and material stock flow of urban structures by municipalities in the Hokuriku region. The result for the “B scenario and technology introduction” in 2050 were 30.5Mt of CO₂ emissions, 7.5Mt of material input, 426.2Mt of material stock, and 19.9Mt of material output. In conclusion, population decline caused by failing birth rate, intensifying urban areas, and the lifetime improvement of domestic houses.
