Biofuel groups and farmer organizations were among some 100 transportation fuel stakeholders who sent a letter this week urging the Biden administration to reverse course on its proposed tailpipe emissions standards for light, medium and heavy-duty vehicles.

“We share the goal of reduced greenhouse gas emissions across the broader economy and, specifically, those from energy production, transportation, and use by society,” the letter states. “EPA’s proposals inhibit the marketplace from identifying the most efficient, lowest cost opportunities to reduce GHG emissions from vehicles and greatly restrict consumer choice. We are concerned that such a prescriptive policy is not in the best interest of the consumer or of U.S. energy and economic security.”

“A diversified portfolio of vehicle and fuel technologies that meets the multitude of transportation needs of Americans and makes meaningful GHG reductions can be achieved while also allowing new zero-emission vehicle, and specifically battery electric vehicle, technologies to advance,” the signatories wrote. “Improved crop yield, innovative biofuel and refined product processing, and manufacturing efficiency tied with carbon capture each represent promising advancements for current liquid and gaseous fuels to continue to accelerate emissions reductions.”

While the majority of the groups signing the letter were petroleum manufacturers, marketers and retailers, the American Farm Bureau, National Corn Growers Association (NCGA), Clean Fuels Alliance America, and the Renewable Fuels Association (RFA) were among the farm and biofuel groups included.

NCGA vice president of public policy Brooke Appleton participated in a press conference on the issue with leaders from the American Petroleum Institute, the U.S. Chamber of Commerce and the American Fuel & Petrochemical Manufacturers. Listen to her comments here:
