Study of Transportation Fuel Life Cycle Analysis: Review of Economic Models Used to Assess Land Use Effects

Life cycle assessments (LCA) have examined the energy inputs and greenhouse gas (GHG) emissions associated with transportation fuels since the 1980s. Estimates of the carbon dioxide (CO₂ ) release from land use change (LUC) associated with biofuel crop production have only recently been incorporated into policy and the broader scientific literature. Agro-economic modeling systems were improved and configured to assess the effect of changes in the agricultural policies, e.g., biofuel production, on land use change and GHG emissions. Those models are used by regulators to assess the impacts of biofuel policies on global agriculture. The objective of this study is to provide an assessment of the key factors going into LUC analysis and how those factors affect the prediction of land use change. The four leading models used in biofuels policy were reviewed and key inputs for LUC were compared. The four models are: (1) Forest and Agricultural Sector Optimization Model (FASOM); (2) Food and Agricultural Policy Research Institute (FAPRI) model; (3) Global Trade Analysis Project (GTAP); and (4) Modeling International Relationships in Applied General Equilibrium (MIRAGE BioFuel (BioF)) model.
