US EPA takes action to implement President Trump’s termination of Biden’s ‘EV mandate,’ heavy-duty NOx rule

U.S. EPA Administrator Lee Zeldin announced March 12 the agency will reconsider the model-year 2027 and later light- and medium-duty vehicles regulation and greenhouse-gas (GHG) emissions standards for heavy-duty vehicles.  

“In addition to imposing over $700 billion in regulatory and compliance costs, these rules provided the foundation for the Biden-Harris electric-vehicle mandate that takes away Americans’ ability to choose a safe and affordable car for their family and increases the cost of living on all products that trucks deliver,” EPA stated.  

“The American auto industry has been hamstrung by the crushing regulatory regime of the last administration,” Zeldin said.  

“As we reconsider nearly $1 trillion of regulatory costs, we will abide by the rule of law to protect consumer choice and the environment,” he added.  

Additionally, EPA said it is reevaluating the other parts of the Biden EPA’s “problematic clean-trucks plan.”  

This includes the 2022 heavy-duty nitrogen-oxides (NOx) rule that the new EPA said “results in significant costs that will make the products our trucks deliver, like food and other household goods, more expensive.”  

Protecting and bringing back American auto jobs is Pillar 5 of Zeldin’s “Powering the Great American Comeback” initiative.  

“President Trump and Administrator Zeldin are fulfilling their promise to bring back American auto jobs and invest in domestic manufacturing to revitalize a quintessential American industry,” EPA stated.  

The news on Zeldin taking action to implement Trump’s termination of the Biden electric-vehicle mandate and heavy-duty NOx rule was announced in conjunction with a number of actions to advance President Trump’s Day One executive orders.  

Combined, these announcements represent what EPA said is “the greatest and most consequential day of deregulation in the history of the United States.”
