Comparison of Biofuel Life-Cycle GHG Emissions Assessment Tools: The Case Studies of Ethanol Produced from Sugarcane, Corn, and Wheat
by L.G.Pereira, O.Cavalett, A.Bonomi, Y.Zhang, E.Warner, H.L.Chum (Renewable and Sustainable Energy Reviews) Highlights: Emissions ranged from 16 to 45 for sugarcane and 43–62 g CO2eq MJ−1 for corn ethanol. LCA tools produce similar results when harmonized to the maximum possible extent. Models are sensitive to methodology,
