Clean Fuels Development Coalition v. EPA

Petitioners representing the ethanol industry challenged EPA’s December 2021 promulgation of “Revised 2023 and Later Model Year Light-Duty Vehicle Greenhouse Gas Emissions Standards.” Their petition asserted that the final rule “exceeds EPA’s authority, implicating serious separation of powers concerns by purporting to arrogate to EPA the authority to effectively mandate the production and sale of electric cars rather than cars powered by internal combustion engines,” and that the final rule conflicts with the Renewable Fuel Standard.
