Supreme Court Invalidates California’s Green Mandates

In a landmark 7–2 decision, the U.S. Supreme Court delivered a major setback to California’s climate agenda, striking at the heart of Governor Gavin Newsom’s environmental goals.

Writing for the majority, Justice Brett Kavanaugh argued that the state’s aggressive electric-vehicle requirements and strict emissions limits may overstep federal authority. The ruling opens the door for fuel and energy companies to challenge the Environmental Protection Agency’s prior approval of these rules.
