Quantitative Model Development to Assess Sustainability in Japan

Abstract

This paper explains the background and structure of the new mathematical model to assess sustainability in Japan. The core part of this model is a computable general equilibrium model, and various environmental issues such as greenhouse gas emissions, solid waste, water environment and land use are included. In addition to that, in order to assess the societal problems such as aging society and economic disparity in Japan, the model has households classified by the age of the household head. Based on the simulation using this model and the discussion with stakeholders, the expected sustainable society in Japan will be quantified.
