The Environmental Protection Agency (EPA) has recently mandated a new Renewable Fuel Standard (RFS2) that reduces the amount of renewable fuels required to be blended into the petroleum fuel supply by approximately three billion gallons. Since cellulosic and advanced biofuels rely heavily on RFS mandates as a key external-funding driver, this change appeared to be a significant setback for the renewable fuels industry. However, taken in context with the larger economic factors, potential technological advances, and potential policy gains, the newly mandated standards do not appear as extreme, and renewable fuels continue to be one of the best paths forward to increased energy and environmental security.
