Life-cycle benefit gains of biofuels over their counterpart fossil fuels compared with the different scenario sets are presented in Table 5. For instance, the base case of biodiesel/diesel gains the benefit 26% (biodiesel has impact score 26% lower than diesel) and bioethanol/gasoline is 22%. For SC1, although both biofuels still have advantage over fossil fuels, only biodiesel has an increase in the life cycle benefit (þ4%), in contrast of bioethanol which loses benefit ( 14%). In the detailed analysis, SC1 indicated GHG TEF has the most influence for all results and the freshwater TEF has increased effects to only biofuel production. SC2 is less concen- trated on GHG emissions, the primary energy resources then rise up to modest benefits (þ6%) because the biofuels gain some benefit from using mostly biomass in biofuel production. Although the various supposed policy target settings directly affect the TEFs, the results of this study are responsive mainly to the GHG emission impact.
