The Environmental Protection Agency was very proud of its new “Strongest-Ever Greenhouse Gas Standards for Trucks” released on Friday, but Clean Fuels Alliance America was extremely disappointed in the outcome.

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.”
