... ethanol production was exempted from meeting GHG reduction targets; new renewable fuel production was required to show reductions in estimated life-cycle GHG reductions relative to a 2005 petroleum baseline specified by EPA. Specifically, biomass-based diesel and advanced biofuels must meet a 50 percent life-cycle GHG reduction; cellulose biofuels must meet a 60 percent reduction; and conventional biofuels, such as ethanol derived from corn starch at new facilities, must meet a 20 percent reduction (EPA, n.d.-b)

... The committee also, consistent with its task, identified needs for additional data, methods for data collection, standardized inputs for LCA, and model improvements that could provide a basis for strengthening the reliability and consistency of how LCA is applied for LCFSs. BOX 1-1 Statement of Task An ad hoc committee of the National Academies of Sciences, Engineering, and Medicine will assess current methods for estimating life-cycle greenhouse gas (GHG)
