US EPA proposes easing Biden heavy-truck emissions rules

The Trump administration announced a proposal to loosen requirements for pollution controls designed to rein in emissions from heavy-duty trucks. According to the administration, these technical changes are expected to provide truck companies with more flexibility than the previous Biden-era rule. This move is anticipated to undermine some of the existing regulations. The US EPA is leading this proposal to ease the strict emissions standards that were previously implemented for the heavy-truck sector across the country.
