Supreme Court to Review Challenge to California's Emissions Authority

The Supreme Court will hear a case challenging California's authority to set its own vehicle emissions standards, which impact greenhouse gas regulations. The case focuses on whether business interests, like liquid fuel companies, have legal standing to sue, arguing that California's rules reduce demand for their products. The court will not address the broader issue of California's right to set these standards, which the EPA has historically allowed through waivers. The Biden administration supports California's regulations, which aim for all vehicles to be zero-emission by 2035.
