Emissions Prediction and Policy Analysis (EPPA) Model
The Economic Projection and Policy Analysis (EPPA) model provides projections of world economic development and emissions along with analysis of proposed emissions control measures. It is used to analyze the processes that produce greenhouse-relevant emissions and to assess the consequences of policy proposals, providing estimates of the magnitude and distribution among nations of their costs and clarifying the ways that changes are mediated through international trade. EPPA is a multi-sector, multi-region computable general equilibrium (CGE) model of the world economy. It utilizes the GTAP dataset, augmented by data on the emissions of greenhouse gases (GHGs), aerosols and other relevant species, taxes, and details of selected economic sectors. Provision is made for analysis of uncertainty in key human influences, such as the growth of population and economic activity and the pace and direction of technical advance.
