The White House has begun reviewing EPA’s draft proposed multi-pollutant emissions standards for passenger vehicles and some larger trucks, offering the latest indication that the agency is on track to release the plan by the end of March as outside groups sharpen their advocacy about the stringency of the requirements.

The proposed rulemaking is one of multiple mobile source emissions rules on the agency’s regulatory agenda, as it also readies its “Phase 3” greenhouse gas proposal for heavy-duty trucks. The Office of Management & Budget’s (OMB) review of the multi-pollutant standards for light and medium duty vehicles will provide an opportunity for industry and environmental groups to weigh in on the plan’s stringency, following clean vehicle incentives in last year’s Inflation Reduction Act (IRA) that are likely to ease emissions reductions even as EPA is pledging a continued focus on improving the performance of internal combustion engine (ICE) vehicles.
