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
