Renewable Fuel Standard (RFS): Overview and Issues

Posted Thu, 10/14/2010 - 01:00

Federal policy has played a key role in the emergence of the U.S. biofuels industry. Policy measures include minimum renewable fuel usage requirements, blending and production tax credits, an import tariff, loans and loan guarantees, and research grants. This report focuses on the mandated minimum usage requirements--referred to as the Renewable Fuel Standard (RFS)--whereby a minimum volume of biofuels is to be used in the national transportation fuel supply each year.

The Energy Independence and Security Act of 2007 (EISA, P.L. 110-140), significantly expanded the renewable fuel standard (RFS) established in the Energy Policy Act of 2005 (EPAct 2005, P.L. 109-58). The RFS requires the use of 9.0 billion gallons of renewable fuel in 2008, increasing to 36 billion gallons in 2022. Further, EISA requires an increasing amount of the mandate be met with advanced biofuelsbiofuels produced from feedstocks other than corn starch and with 50% lower lifecycle greenhouse gas emissions than petroleum fuels.
