This effort follows an executive order by Governor Gavin Newsom in response to illegal federal actions to revoke California’s Clean Air Act waivers. In response to illegal federal efforts to revoke California’s clean air waivers, Governor Gavin Newsom signed an executive order on June 12, 2025. The order directed the California Air Resources Board, the California Energy Commission, Governor’s Office of Business and Economic Development, California State Transportation Agency, and Department of Consumer Affairs to assess additional actions to spur light-, medium-, and heavy-duty zero emission vehicle (ZEV) adoption in California, and to deliver formal recommendations for additional actions to the governor in August. Decades of cleaning our airAlthough California standards have dramatically improved air quality, the state’s unique geography means air quality goals still require continued progress on vehicle emissions. Over the last 50 years, the state’s clean air efforts have saved $250 billion in health costs through reduced illness including reducing diesel-related cancer risk nearly 80%.
