Supreme Court to Review California's Vehicle Emissions Standards Amid EPA Waiver Challenge

Dec 13, 2024, 08:05 PM

The U.S. Supreme Court has agreed to hear a case challenging California's authority to set its own vehicle emissions standards, including regulations aimed at curbing greenhouse gas emissions. The case, brought by fuel producers including Valero Energy Corp., questions whether these companies have legal standing to sue over the regulations. The Environmental Protection Agency (EPA) had previously granted California a waiver under the Clean Air Act to implement stricter emissions standards due to the state's unique air pollution issues. The Supreme Court's decision to review the case comes at a time when California's auto rules are under threat following Donald Trump's presidential election victory, which could impact future EPA waivers needed for California to enforce its regulations.
