Section 211 of the Clean Air Act requires EPA to set annual Renewable Fuel Standard (RFS) volume requirements for four categories of biofuels: cellulosic biofuel, biomass-based diesel, advanced biofuel, and total renewable fuel. On November 23, 2016, EPA finalized rules under the RFS program, increasing the amount of renewable fuels that must blended into gasoline and diesel fuel in 2017.
Under the new RFS rules, total renewable fuel volumes will grow by 1.2 billion gallons from 2016 to 2017, a 6 percent increase.
In the final rule, EPA describes the significance of renewable fuels, currently and in the future:
Today, nearly all of the approximately 142 billion gallons of gasoline used for transportation purposes contains 10 percent ethanol (E10), and a substantial portion of diesel fuel contains biodiesel. Renewable fuels represent an opportunity for the U.S. to move away from fossil fuels towards a set of lower lifecycle GHG transportation fuels, and the RFS program provides incentives for these lower lifecycle GHG fuels to grow and compete in the market.
The final RFS rules have been submitted to the Federal Register and will be published in the coming weeks. More information about the RFS program and the final RFS rule can be found on the EPA website.
