In an announcement that was welcomed by both the supporters and critics of ethanol as a renewable fuel, EPA’s Office of Inspector General (OIG) said it intends to “begin preliminary research on lifecycle impacts of the EPA’s renewable fuel standard (RFS).”

The RFS program is a national policy that requires a certain volume of renewable fuel to replace or reduce the quantity of petroleum-based transportation fuel, heating oil, or jet fuel. For a fuel to qualify as a renewable fuel under the RFS program, it must achieve a reduction in greenhouse gas (GHG) emissions compared to a 2005 petroleum baseline. GHG reductions are calculated on a life-cycle basis for four types of renewable fuel under the RFS. Read this article to learn more about the life-cycle.
