Environmental Impact and Sustainability Applied General Equilibrium model (ENVISAGE)
Environmental Impact and Sustainability Applied General Equilibrium model (ENVISAGE) is a computable general equilibrium (CGE) model that assesses interactions between economies and the global environment as affected by anthropogenic greenhouse gas emissions.
The model is designed to analyze a variety of issues related to the economics of climate change, including:
- baseline emissions of CO2 and other greenhouse gases,
- impacts of climate change on the economy,
- adaptation by economic agents to climate change,
- greenhouse gas mitigation policies—taxes, caps and trade,
- the role of land use in future emissions and mitigation, and
- the distributional consequences of climate change impacts, adaptation and mitigation—at both the national and household level.
Key questions addressed:
- How do changes in temperature effect economic variables such as agricultural yields or damages at sea level rise?
- How do policies, such as cap and trade or taxes, mitigate the impacts of GHG emissions and atmospheric concentrations?
Sample data inputs:
- Energy volumes and CO2 emissions from the Global Trade Analysis Project (GTAP) database
Sample quantitative outputs:
- Greenhouse gas emissions
- Economic impacts
