The Renewable Fuel Standard (RFS) requires increasing volumes of renewable fuels like ethanol to be blended with gasoline, reaching 36 billion gallons in 2022. The RFS was established by Congress in 2005 and expanded in 2007 to provide market stability and access for biofuels. In 2015, ethanol production supported over 357,000 jobs and contributed $43.9 billion to GDP. Ethanol reduces gasoline imports and consumer fuel costs while cutting greenhouse gas emissions and air pollution compared to gasoline. The RFS drives innovation in renewable fuel technologies to expand biofuel production and use.
