Last week, the EPA released the strictest limits on tailpipe emissions in its history, a move that figures to spur more EV sales and cut down on pollutants and greenhouse gas emissions in the transportation sector, the country’s biggest driver of greenhouse gas emissions.
The EPA said its proposed light-duty standards for the 2032 model year could lead to a 56 percent cut in projected fleetwide average greenhouse gas emissions target levels, compared with 2026 model year standards.
That will be a significant leap forward, involving new R&D programs and component enhancements.
Suppliers are still sorting through the proposed rules and the impact they will have on their operations and development programs, said Ann Wilson, senior vice president of government affairs at the Motor & Equipment Manufacturers Association, which represents more than 1,000 U.S. suppliers of original equipment and aftermarket parts.
“We’ll need time to roll up our sleeves with our members and look at the specifics of the proposal,” she told Automotive News. “We have long supported the transition to zero-emission vehicles, but this is a momentous shift for the industry and this country.”
The Motor & Equipment Manufacturers Association will push for any new standards to be performance-based and allow for the adoption of multiple technologies including hydrogen-powered systems, not just battery-electric systems, she said.
“In the past, EPA has always been very willing to listen to that, and they’re well aware of the role that these varying technologies play,” Wilson said. “But we’re going to lean heavily on our members to understand the practicalities of this proposal.”
