EPA has issued a supplemental determination to release its lifecycle greenhouse gas (GHG) analysis of grain sorghum used as a feedstock to produce ethanol under the RFS program. Ethanol made from grain sorghum at dry mill facilities that use natural gas for process energy meets the lifecycle greenhouse gas emissions reduction threshold of 20% compared to the baseline petroleum fuel it would replace, and therefore qualifies as renewable fuel. Also, grain sorghum ethanol produced at dry mill facilities using specified forms of biogas for both process energy and most electricity production, has lifecycle GHG emission reductions of more than 50% compared to the baseline petroleum fuel it would replace, and that such grain sorghum ethanol qualifies as an advanced biofuel under the RFS Program.
