Abstract: The objective of this paper is to conduct Life Cycle Assessment (LCA) and Environmental Life Cycle Costing (ELCC) studies for lignocellulosic bioethanol blends [E10 and E85 (10% and 85% by volume of bioethanol with gasoline, respectively)] and conventional gasoline (CG). To compare the environmental performance and economic advantage of the selected fuel blends, the impact potentials and the cost of fuel applications per kilometer by a middle size car was evaluated. According the LCA results, one kilometer driven by E10 and E85 fueled vehicles could reduce the greenhouse gas (GHG) emissions by 4.3% and 47% and ozone layer depletion emissions by 3% and 66%, respectively, relative to CG. However, shifting from gasoline to bioethanol increases the emissions that contribute to eutrophication and photochemical ozone depletion. In terms of acidification potential, E85 shows a more favorable result relative to E10 and CG. According to the ELCC analysis, E85 fuel use provides a 23% lower driving cost relative to CG based on a-1 km driving distance. The results showed that E85 seems to be the best alternative in terms of both GHG emission and fuel production cost reduction compare to CG.
