Renewable Fuel Standard

Repost This

The Renewable Fuel Standard (RFS) is defined in the Energy Security and Independence Act of 2007 (PDF), revising and extending provisions of the Energy Policy Act of 2005 (PDF). It defines several categories of biofuels and specifies minimum production levels for each through 2022. In particular, the RFS sets targets for total annual production of biofuels and for a sub-category termed "advanced biofuels," which excludes corn ethanol. The RFS does not call explicitly for the production of corn ethanol in any of its provisions, but corn ethanol can (and is expected to) account for essentially all of the RFS-mandated biofuel production that is not in the category of "advanced biofuel". This graphic does not show the mandate for advanced biofuel, only for non-advanced.
