CLEAN FUELS ALLIANCE AMERICA v. ENVIRONMENTAL PROTECTION AGENCY AMERICAN FUEL & PETROCHEMICAL MANUFACTURERS, ET AL Consolidated with 20-1113
The D.C. Circuit dismissed consolidated petitions challenging the EPA's 2020 Renewable Fuel Standard because intervening statutory changes and the superseding 2022 Rule rendered the case moot. The court held that petitioners could not seek an advisory opinion on a future agency policy when the underlying legal framework had materially shifted.
