Abstract
This Paper presents a simulator which could calculate future Japanese economy and its CO2 emission in 2040. This simulator consists of macro model, industry model and energy model. It is characterized by high-speed calculation, model integrality and easy handling. By using this simulator, we could get quantitative answer on the economic-environmental questions about future Japanese CO2 emission.
By using Monte-Carlo type simulation, we find that the relation between GDP and CO2 emission would be relaxing in future because of economic structural change.
