Human System Model
Economic Projection & Policy Analysis (EPPA) Model
The EPPA model provides projections of world economic development at a regional and sectoral level, including the economic implications of greenhouse gas (GHG) emissions, conventional air pollution, land-use change, food demand, and natural resource use.
EPPA simulates the evolution of economic, demographic, trade and technological processes involved in activities that affect the environment. We use it to investigate the economic implications of a wide range of phenomena, including:
- Climate and environmental impacts (e.g. changes in crop yields and human health)
- Resource depletion and new technologies
- Policies aimed at reducing emissions of GHGs and other pollutants
- Policies aimed at limiting trade or land-use change
- Deployment of specific technologies (e.g. wind power, solar power, carbon capture and storage, crop yield-enhancing technology)
- Simulations of future emissions of GHGs and other pollutants as input for the MIT Earth System Model (MESM).
- Land-use change and cover as input for the MIT Earth System Model (MESM).
- Energy, economic, and emission projections for the MIT Global Change Outlook.
The core model includes 18 global regions, but its framework has been applied with greater spatial, economic sector and household resolution for detailed studies.
