Economic Measures for Evaluating CO2 Emission Reduction in Japan by Using the Integrated Model of Multi-sectoral Macroeconomy and Energy

摘要

In recent years policy makers have been eager to develop economy-energy models that can test the effectiveness of environmental policies for realizing low-carbon economy in Japan. We have developed the Integrated Multi-sectoral Macroeconomic Energy Model that can evaluate the amount of CO2 emission reduction effects of macroeconomic policies. This paper presents the outline of the model, and shows the results of the simulation about the use of the tax revenue and the oil price increase. About the use of carbon tax revenue the GDP decrease of the case of income tax reduction is more than that of the case of public investment. The reduction rates of production by industry sector vary from 0.09% ("Construction" sector) to 4.7% ("Iron, steel and metal" sector).
