The MIT Emissions Prediction and Policy Analysis (EPPA) model: version 4
The Emissions Prediction and Policy Analysis (EPPA) model is designed to develop projections of economic growth and anthropogenic emissions of greenhouse related gases and aerosols.
This paper provides documentation of EPPA version 4. Compared with the previous EPPA version, EPPA4 includes the following changes:
- Greater regional and sectoral disaggregation;
- The addition of new advanced technology options (natural gas combined cycle, natural gas combined cycle with carbon capture and sequestration, integrated gas combined cycle with carbon capture and sequestration);
- Explicit representation of renewable electricity (solar and wind, biomass);
- Liquid fuel from biomass;
- Updating of the economic base data to the GTAP 5 data set (Dimaranan and McDougall, 2002) including newly updated input-output tables for Japan, the US, and the EU countries, and rebasing of the data to 1997;
- Disaggregation of hydroelectric power from electricity sector;
- Disaggregation of household transportation into purchased and own-supplied transport;
- Updating of the demographic data and future projections (UN, 2000, 2001);
- Different options for international trade in natural gas (globally homogenous, regional trade, and Armington specification);
- Introduction of sector-specific constraints on greenhouse gases;
In addition, the model has received a general revision of projected economic growth and inventories of non-CO2 greenhouse gases and urban pollutants.
