Impact of different hypothesis on d+i LUC factor (g eq. CO₂/MJ computed over a 20 year period) (De Cara et al., 2012). Partethanol: ethanol part (on energy basis) in the total biofuel mix examined. CFC, CPC, CMLOC: these parameters respectively indicate that the model or scenario allows the conversion of forest, grassland, marginal land (including savannah, mountain land) in cropland and conversely. PeatxBiod indicates that the scenario allows conversion from peat land and considers biodiesel production. Rdt is associated to crop yield and indicates here that crop yields are likely to change due to the increase of biofuel demand. Dde indicates that model considers the reaction of demand to price changes. Copdt indicates that coproducts are accounted in the study and gives rise to LUC credits. AmLatS, SEAsieS, AmNordS, EuropeS described the geographical supply area of biofuel, respectively: Latin America, South East Asia, North America and Europe. Models can consider several areas together.
