Clean Fuels Expresses Disappointment in EPA’s GHG Standards for Heavy Duty Vehicles

Mar 29, 2024 | Federal Affairs, News, News Release


WASHINGTON, DC – Today, Clean Fuels Alliance America expressed extreme disappointment in the Environmental Protection Agency’s final Greenhouse Gas Emissions Standards for Heavy-Duty Vehicles-Phase 3. In the rule, EPA adopts new standards that are designed expressly to incentivize electric vehicles for model year 2027-2032 heavy duty vehicles. The standards are part of GHG emission regulations for trucks and buses.

EPA did not evaluate use of biodiesel and renewable diesel as part of engine systems to meet the new standards, focusing primarily on tailpipe emissions. However, the agency considered a range of alternative fuel and engine configurations, such as natural gas and hydrogen. EPA did recognize that equipment makers will continue to have the option to use biodiesel and renewable in their compliance strategies.

“EPA’s rule flatly dismisses the benefits of biodiesel and renewable diesel as the lowest-cost and most widely available options to kickstart decarbonization of the heavy-duty vehicle sector,” said Kurt Kovarik, Vice President of Federal Affairs with Clean Fuels. “There should be no uncertainty that biodiesel and renewable diesel also reduce criteria pollutants from heavy-duty vehicles, which will continue to be manufactured and used during the timeframe of this rule. EPA should recognize that biodiesel and renewable diesel merit a role in meeting these emission standards for heavy-duty vehicles.”
