The Renewable Fuels Association and LanzaJet are among U.S. ethanol interests seeking to intervene in a legal challenge of the European Union’s ReFuelEU Aviation Regulation, which effectively bans the use of renewable, crop-based biofuels like corn ethanol as a feedstock for decarbonizing the aviation sector. LanzaJet operates the world’s first ethanol-to-jet biorefinery in Georgia. Also collaborating in the intervention are U.S. Grains Council and Growth Energy.

The application to intervene in the proceedings supports a challenge brought by ePURE, a trade association representing European ethanol producers, and Pannonia Bio, one of Europe’s largest ethanol producers. Their application seeks to annul the relevant provisions of the ReFuelEU Aviation Regulation, which was adopted by the EU in 2023 and is set to take effect in 2025. A similar challenge was brought against the FuelEU Maritime Regulation, and members of the U.S. ethanol industry are seeking to intervene there, as well.
