(NAFB.com) – Debate over U.S. biofuel policy is intensifying ahead of the summer driving season as lawmakers weigh changes to blending requirements under the Renewable Fuel Standard. According to Reuters, ethanol producers are pushing for higher blending levels, while refiners seek greater flexibility. Bloomberg reported ongoing disputes over waiver policies and compliance costs. The Renewable Fuels Association said expanded E15 use could boost corn demand and lower fuel costs for consumers. The Environmental Protection Agency is reviewing policy options as pressure grows from both sides. The American Coalition for Ethanol continues to advocate for year-round E15 access. Economists say biofuel policy significantly affects commodity markets. With summer fuel demand expected to rise, upcoming decisions could have immediate impacts on both energy and agriculture sectors nationwide.
