Supreme Court to Rule on Challenge to California's Emissions Standards

The U.S. Supreme Court will hear a case challenging California's authority to set its own vehicle emissions standards, which are stricter than federal regulations and aim to reduce greenhouse gases. The case focuses on whether business interests, like liquid fuel companies, have the legal standing to sue, arguing that California's rules could decrease demand for their products. The court will not address the broader issue of the legality of California's ability to set its own standards, a power granted by the EPA under the Clean Air Act. The Biden administration supports California's waiver, which was contested by 17 Republican-led states.
