MIT Emissions Prediction and Policy Analysis (EPPA) Model

From Open Energy Information

EPPA is a recursive-dynamic multi-regional global general equilibrium model that uses the GTAP dataset with additional data for greenhouse and urban gas emissions.

This tool is included in the Development Impacts Assessment (DIA) Toolkit from the LEDS Global Partnership.


EPPA is the part of the MIT Integrated Global Systems Model (IGSM) that represents the human systems. The EPPA model simulates the world economy through time to produce scenarios of greenhouse gases, aerosols, other air pollutants and their precursors, emitted by human activities. These emissions scenarios are input into a coupled model of atmospheric chemistry, climate and terrestrial ecosystems to produce scenarios of anthropogenic climate change and changes in atmospheric composition. Version 4 of EPPA covers 28 regions and countries.
