The Trump administration has proposed relaxing pollution regulations for trucks that were established under the previous Biden administration. The move represents another step in rolling back environmental rules that affect makers of vehicles powered by fossil fuels. Environmental Protection Agency Administrator Lee Zeldin stated at an event that the revisions would benefit manufacturers and operators by lowering costs and avoiding rushed product launches. The changes target a 2023 rule limiting nitrogen oxide emissions from truck tailpipes starting with 2027 models. A public comment period is still required before final approval. The agency also plans to shorten the required emissions warranty period from 450,000 miles to 100,000 miles while claiming to retain nearly 90 percent of the original reductions. Officials estimate the amendments would save 12 billion dollars overall and up to 6,000 dollars per new truck. Environmental groups have criticized the proposal, arguing it would increase health risks from smog and soot in communities nationwide and urging the agency to keep stronger standards instead.
