WASHINGTON – October 19, 2026 – The American Biogas Council (ABC) applauds Congresswoman Mariannette Miller-Meeks (R-Iowa) and six other U.S. Representatives for their letter urging the U.S. Environmental Protection Agency (EPA) to expand Renewable Fuel Standard (RFS) eligibility for renewable fuels used in domestic maritime transportation.
Some qualified renewable fuels used in vessels serving domestic routes cannot currently generate RFS credits because of EPA’s definition of ocean-going vessels. The signers, which also include Reps. Randy Feenstra (R-Iowa), Mike Flood (R-Nebraska), Zach Nunn (R-Iowa), Michelle Fischbach (R-Minnesota), Derek Schmidt (R-Kansas), and Mark Alford (R-Missouri), urge EPA to clarify that U.S. inland and coastal vessels can help generate credits from the renewable fuels they use and revise the RFS definition so domestic operations are not excluded solely because of engine type.
“Expanding RFS eligibility would open an important new market for American-made bio-LNG and other renewable fuels,” said Patrick Serfass, Executive Director of the American Biogas Council. “Bio-LNG is made by processing organic waste — including farm manure, wastewater, and food waste — into renewable natural gas and liquefying it. It offers operators of LNG-capable vessels domestically-produced renewable fuel options while making use of existing LNG infrastructure. This helps put millions of tons of waste to beneficial use. Making the changes the letter requests, would help create demand for domestic, renewable fuels, support American farmers and businesses, and encourage investment in domestic fuel production, port infrastructure, and maritime operations — all without new legislation or federal spending. With diesel prices high, this is also an opportunity to advance the administration’s goal of restoring American Maritime Dominance.”
