Farmers Union comments on greenhouse gas emissions rule

Oct. 5, 2021

ST. PAUL – In comments submitted to the U.S. Environmental Protection Agency last week, Minnesota Farmers Union (MFU) urged the agency to support moving toward mid-level ethanol blends.


“This is a priority for our members, not only because it will provide significant benefit to Minnesota’s rural economy, but also because it will immediately curb greenhouse gas emissions, improving our environment and contributing to the fight against climate change,” said MFU President Gary Wertish in the letter. “We see biofuels—and moving toward high-octane mid-level ethanol blends—as a near-term, cost-effective step we can take to lower the carbon intensity of our transportation fleet.”


The comments were submitted in response to the proposed Revised 2023 and Later Model Year Light-Duty Vehicle Greenhouse Gas Emissions Standards (“Proposed Rule”; published at 86 Fed. Reg. 43,726).


National Farmers Union also filed comments, with NFU President Rob Larew detailing the challenges climate change brings to family farmers and how biofuels can address some of those concerns.


“Biofuels have played an important role in supporting family farms, which have faced a struggling economy and significant pressure to stay in production,” Larew said. “NFU has long supported the use of ethanol as a fuel additive for gasoline formulations to enhance octane levels. Use of higher ethanol blends provides significant benefits to the rural community, the environment and beyond.”


MFU made several specific asks of the EPA, including:

  • Requiring specific octane levels under the Clean Air Act;
  • Easing the ability to use mid-level ethanol blends as a certification fuel;
  • Ensuring the appropriate R-factor for increased ethanol volumes;
  • Working with the industry to resolve Reid Vapor Pressure (RVP) restrictions, and
  • Establishing polices to promote the manufacture and sale of Flex Fuel Vehicles (FFVs), including by restoring incentives.
