The U.S. Environmental Protection Agency (EPA) has sent several California emissions waivers to Congress for potential reversal, a move that could help restore a more consistent national framework for vehicle and equipment standards. The waivers allow California to impose requirements that are stricter than federal rules, including vehicle emissions standards that can shape compliance obligations beyond the state’s borders.

A patchwork of state-driven mandates does not stay inside state lines. It can complicate production, supply chains, fleet planning and long-term investment decisions for companies across the country.

“Ohio manufacturers should not be forced to plan around rules written in Sacramento,” said James Lee, OMA managing director of public policy services. “When California policy becomes de facto national policy, it affects production, supply chains, fleet decisions and investment far beyond California. EPA is right to put those consequences back under federal review.” 6/18/2026
