Supreme Court to Review California's Vehicle Emissions Standards Challenge

The U.S. Supreme Court will hear a case challenging California's authority to set its own vehicle emissions standards, a provision allowed under the Clean Air Act due to the state's unique pollution issues. This follows a legal battle initiated when the Trump administration revoked California's waiver for stricter standards, a decision reversed by the Biden administration. Ohio and 16 other states argue the waiver violates the constitutional principle of state equality, while environmental groups claim the lawsuit aims to undermine the Clean Air Act. The D.C. Circuit Court previously upheld the EPA's authority to grant such waivers.
