Abstract

A large amount of resource consumption and expansion of social infrastructures has supported the rapid economic growth of Japan. However, from the perspective of the finite resources, shift to a stock-based society that reduces the amount of material input and waste is expected in the future. Therefore, it is important to understand amount of the future demand for material stock. In this study, we estimated future demand for material stock of urban structures?housing, office building, road, railway and sewer by level of cities, towns and villages in order to understand detail of regional characteristics. The result obtained from the estimation indicates that the difference of material stocks by multiple scenarios became 190 Mt in 2050.
