FIRST ON FOX: The Trump administration is proposing to slash Biden-era truck emissions regulations in a move officials say would save the trucking industry about $12 billion and ease supply chain costs that make everyday goods more expensive for Americans.
“Collectively, these savings will be passed on to American families through lower costs for food, household goods, and other products trucks deliver, while still maintaining strong environmental protections and ensuring clean air,” read the Environmental Protection Agency (EPA) press release first viewed by Fox News Digital.
The EPA has proposed changes to heavy-duty truck emissions rules that would save truckers an estimated $12 billion, including up to $6,000 per new truck, helping lower transportation costs and prices for American families.
The proposal would eliminate DEF-related engine deratements and speed restrictions for new highway engines and vehicles, as well as new nonroad engines and equipment, including farm machinery, replacing them with warning alerts so operators can keep working until repairs can be made safely.

Previous policies “make delivering everything more expensive and so that’s going to all be passed on to the consumer as well. By making these trucks cheaper and more reliable, we are making sure that the supply chain stays as cheap as possible for the American people,” EPA air chief Aaron Szabo told Fox News Digital in an interview.
The proposal would also reduce costly emissions warranty requirements from the 2023 rule while keeping nearly 90% of the planned NOx emissions reductions and giving manufacturers more time and flexibility to meet the updated standards.
Szabo said the proposal addresses a major problem caused by DEF system failures, which can force trucks and farm equipment into “limp mode” by reducing their speed to just five miles per hour.

He said with more than 200 possible failure codes, the deratements can leave truckers stranded on the side of the road and farmers losing hours—or even days—of productivity during critical work like harvesting.
“We’re both making the products more reliable and decreasing the impact from DEF. And we’re also bringing down the price of the whole supply chain by reducing the cost of these new trucks,” Szabo said.
Secretary of Agriculture Brooke Rollins told Fox News Digital in a statement that the issue has “shown the true cost of government overreach.”

“Our rural communities rely on diesel powered engines to deliver their food, families, electricity, and so much more to where it needs to go. The billions in savings will directly benefit those who feed, fuel, and clothe our nation,” Rollins said.
The latest proposal follows Trump’s broader pledge to roll back Biden-era green regulations after he returned to office.
“We will terminate the Green New Deal, revoke the electric vehicle mandate, and unleash American energy,” Trump said in his inaugural speech.

Szabo said the Biden administration tried to push Americans into electric trucks with rules it enforced.
“That’s what the Biden administration was doing. They were forcing people to not have choice anymore, taking away their freedom to choose what kind of vehicle and telling them you have to buy an electric vehicle,” he added.
Fox News Digital reached out to the Office of Joe Biden for comment.
