The EPA has released changes to the National Renewable Fuel Standard program, which specifies annual volumes of renewable fuels, including cellulosic biofuel, biomass-based diesel and advanced biofuel, blended into transportation fuel. It is the first time that the EPA has set standards for renewable fuels by category. By 2022, the volume standard will rise to 36 billion gallons of biofuel. Last year, 11.1 billion gallons of biofuel were produced. The EPA has also updated the definitions and criteria for renewable fuels and their constituent feedstocks. The biofuels that meet the new requirement for greenhouse gas emission limits are: corn-based ethanol produced using efficient technologies; soy-based biodiesel; biodiesel made from waste grease, oils, and fats; sugarcane-based ethanol; and fuels derived from cellulosic materials.
