Developing Lcfs For Biofuels: Getting It Right For Corn Ethanol, Kenneth Cassman, Adam Liska
Adam Liska Papers
• Corn ethanol will be first to test the newly developed LCFS assessment methods; substantial amounts of other biofuels will come several years later
• Accurate valuation of direct-effect GHG emissions from corn ethanol is the foundation of the LCFS process; these affects vary with ethanol biorefinery type and corn feedstock supply
• Different reference GHG emissions values are needed for each major class of ethanol plants
• The BESS model provides the most up-to-date, scientifically sound estimate of corn-ethanol GHG emissions; can BESS and GREET reach agreement?
• Certification and compliance tools are also needed

Adam Liska Papers
Rapid development of regulatory mechanisms to mitigate greenhouse gas (GHG) emissions requires that the biofuel industry employ standard methods to evaluate biofuel systems comprising both crop production systems and biorefineries. Biofuel systems associated with a variety of organic feedstocks have a range of performance capabilities, and recent life-cycle assessment studies of these different systems have used inconsistent methods, leading to confusion about biofuel energy efficiency and GHG mitigation. Hence, there is a critical need for well documented life-cycle metrics for consistent biofuel evaluation that are established and supported by a national or international governing body. Standardization of net energy and …
