On Thursday, March 12th, EPA Administrator Zeldin announced that the EPA would begin the process of reconsidering the Biden Administration's emissions regulations governing light, medium, and heavy-duty vehicles. This reconsideration action includes the “GHG3” rule for trucks that would have impacted model year 2027-2032 vehicles. The regulation would have required an annual increase percentage of “zero emissions vehicles” (ZEVs), with MY 2032 ZEV requirements set at 60% for light-heavy vocational vehicles, 40% for medium-heavy vocational vehicles, 30% for heavy-heavy vocational vehicles, 40% for day cab tractors, and 25% for sleeper cab tractors. The rule was structured in a way that would only drive electric truck investment, despite technology and infrastructure challenges.
