Abstract
This study estimates total power generation and its component, and greenhouse gas (GHG) abatement cost for Japanese 2050's 80% GHG emissions reduction target. An economic model (General equilibrium model) is used for the estimation and energy technological model results are reflected in the energy representation in the economic model so that the energy flow outcomes can be more realistic than the outcomes of general economic model which typically uses abstract function. As results, GDP losses associated with the GHG emissions reduction in 2050 is 0.4% which is around 2% lower than conventional economic model approach. The emissions reduction potential in the energy technological model could be different from that of original in the economic model, which consequently changes production and household activities and carbon tax revenues.
