There's a growing consensus among the budding cellulosic ethanol community that the renewable fuels standard (RFS) is not doing its job. Enacted in 2005 and amended in 2007, the RFS was part of legislation designed to spur greater production of renewable fuels by ensuring demand through the establishment of mandatory blend levels for those fuels. But for the second year in a row, the EPA is proposing to drastically reduce the cellulosic biofuels volume requirement. While probably necessary due to lack of available fuel, continual lowering of the mandate brings into question the effectiveness of the program and the unintentional negative impacts it could have on the industry it was created to assist.
