Thousands of farmers from across the country signed a letter that was sent to President Joe Biden last week expressing concern that his administration is taking a short-sighted approach to addressing climate change by prioritizing the use of electric vehicles over biofuels, such as corn ethanol, as it works to drastically lower the nation’s greenhouse gas emissions.

“If we are going to address climate change and meet our sustainability goals, we are going to have to take a multi-pronged approach, that includes tapping into higher levels of biofuels, such as corn ethanol, which offers an immediate climate solution,” reads the National Corn Growers Association letter that was signed by 3,466 farmers.

The farmers said it could take years before EVs become popular with consumers, which means the administration must expand its focus and efforts to address GHGs with solutions that are available now. “As a low-carbon, clean energy source and an affordable, homegrown fuel, ethanol serves as a critical pathway for agriculture and rural America to contribute to a sustainable future,” the letter noted.

The letter, which drew thousands of signatures in less than a week, comes as the U.S. Environmental Protection Agency prepares to release its light- and medium-duty vehicle tailpipe emissions standards for 2027-2032. To help meet the standards, the president has set a goal that 50% of all vehicle sales will be electric by 2030. A similar rulemaking is also being considered through the National Highway Traffic Safety Administration.
