The Renewable Fuels Association and National Farmers Union have filed a lawsuit against the U.S. Environmental Protection Agency in the D.C. Circuit Court of Appeals challenging recently finalized light- and medium-duty vehicle emissions standards.

This action is separate from the lawsuit filed last week by National Corn Growers Association, American Farm Bureau Federation, and American Petroleum Institute to “ensure that ethanol producers and farmers have a strong and independent voice in the proceedings.”

RFA and NFU claim in the lawsuit that “EPA clearly lacked the authority to adopt the regulation, which essentially mandates the production of battery electric vehicles while, at the same time, ignoring other technologies—like low-carbon ethanol and flex fuel vehicles—that reduce emissions from light- and medium-duty transportation.”

“EPA grossly exceeded its statutory authority by finalizing regulations that effectively mandate the production of EVs, while blatantly excluding the ability of flex fuel vehicles and low-carbon, high-octane renewable fuels like ethanol to achieve significant vehicle emissions reductions,” said RFA President and CEO Geoff Cooper. “By relying on the false premise that battery electric vehicles have ‘zero emissions’ and no impact on the climate, the regulation essentially forces automakers to swiftly ramp up the production of EVs and phase out liquid-fueled vehicles that could actually deliver the same—or better—emissions reductions. America’s ethanol producers and farmers would be severely injured if EPA’s regulation were allowed to stand.”
