MEMA supports EPA’s final rule on emission standards for future vehicles

MEMA and its members support the objectives of the EPA to improve national air quality through improvements to light- and medium-duty vehicles and applauds the agency for adopting improvements advocated by MEMA.


MEMA, The Vehicle Suppliers Association (MEMA), and its members welcome the Environmental Protection Agency’s (EPA) final rule for Multi-Pollutant Emissions Standards for Model Years 2027 and Later Light-Duty and Medium-Duty Vehicles, released March 20, 2024. 

MEMA and its members support the objectives of the EPA to improve national air quality through improvements to light- and medium-duty vehicles and applauds the agency for adopting improvements advocated by MEMA. The supplier industry directly designs and manufactures vehicle components and systems that enable the transformation of the transportation sector. Suppliers play an essential role in providing the technology inherent to advanced internal combustion engine vehicles, plug-in hybrid electric vehicles (PHEVs), battery electric vehicles (BEVs) as well as hydrogen fuel cell vehicles. 

The EPA final rule includes an amended and more comprehensive analysis of technological alternatives, such as plug-in hybrid vehicles (PHEV) and additional technologies—an enhancement MEMA strongly urged the EPA to undertake. Such a detailed examination ensures greater regulatory clarity, empowering the industry to move forward with implementation.

Further refinements in the analyses address MEMA’s concerns regarding the importance of technology neutrality. Consequently, alternatives including hybrid gas/electric and other technologies can serve as viable options within the market mix used to meet overall requirements in the national fleet. 

MEMA notes that EPA’s selection of Alternative Three will facilitate a more gradual, steady implementation of the stated emissions requirements. This approach will provide global supply chains greater flexibility to adapt to the regulations while reorienting to meet market demands and restructuring needs. 

This balanced set of requirements and expectations will foster innovation in a coordinated direction, aligned with U.S. policy, and not mandate application of a narrowly defined technology path to make a positive impact on the country’s urgent environmental goals. 

The revised analyses also updated and expanded examinations and impacts relating to national infrastructure needs and achievements and the balance that must be struck in pushing for more electrification than may be possible in the near-term. MEMA will review the final regulation as it becomes available and confer with MEMA member companies.
