The basic objective of this research was to estimate land use changes associated with US corn ethanol production up to the 15 billion gallon Renewable Fuel Standard level implied by the Energy Independence and Security Act of 2007. Estimated land-use changes were estimated to calculate Greenhouse Gas Emissions associated with the corn ethanol production. The main model that was used for the analysis is a special version of the Global Trade Analysis Project (GTAP) model. It is a computable general equilibrium model that is global in scope. The version used for this analysis has up to 87 world regions and 57 economic sectors plus the biofuel sectors that were added for this analysis. There are many different versions of the GTAP model. It is used by thousands of economists around the world for analysis of trade, energy, climate change, and environmental policy issues. The model is publically available with documentation of the model and data base. The version used in this analysis contains energy and GHG emissions (GTAP-E) and also has land use (GTAP-AEZ).
