Vehicle Emissions
Jump to Section
MEMA vehicle suppliers are at the forefront of technological development, anticipating the needs of customers and investing in technology solutions to meet emissions standards. Suppliers have invested significant resources in U.S.-based research and development, enabling technologies to be designed, prototyped and validated domestically before being deployed domestically.
MEMA shares the administration’s objectives of increasing domestic manufacturing. MEMA urges policy makers to provide suppliers with the stability they need to keep investing and innovating in the U.S.
