On June 13, 2025, California filed a high-profile lawsuit against the Trump administration for revoking key waivers under the Clean Air Act—a move that threatens the state’s authority to enforce stricter vehicle emissions standards in support of its ESG and carbon neutral strategy.

Governor Gavin Newsom and Attorney General Rob Bonta, backed by 10 other states, argue the administration’s use of the Congressional Review Act (CRA) to cancel three waivers is unlawful. These waivers, reinstated under the Biden administration, are essential for California’s ambitious plans to phase out gas-powered vehicle sales by 2035, enforce stringent diesel truck rules, and cut nitrogen oxide (NOx) emissions.

Why This Matters:

• California’s emission rules are critical to achieving $91 billion in economic benefits and $45 billion in healthcare savings by 2040.

• The lawsuit challenges the federal government’s attempt to centralize environmental policymaking, threatening state-led ESG innovation.

• 17 states and D.C. have already adopted California’s standards; 14 of those also follow its Zero-Emission Vehicle (ZEV) program, amplifying national impact.

Competing Visions:

• California’s stance: Decades of legal precedent allow it to set tougher rules due to its unique air pollution challenges, and its actions align with broader climate and ESG goals.

• Trump administration’s view: Seeks uniform federal standards, arguing that California’s separate rules inflate costs and extend beyond its mandate.

The case could head to the Supreme Court, with wide-reaching implications for state autonomy in environmental governance. A ruling in California’s favor would reinforce decentralized climate leadership; a loss could undermine localized carbon neutral strategies and ESG-driven innovation across the U.S.
