GOP targets California-emission waivers to curb cross-state rules
Senate Republicans, led by Sen. Cynthia Lummis, are using the Congressional Review Act to nullify EPA waivers that let California set stricter vehicle and small-engine emissions standards, arguing this curbs California’s outsized regulatory influence; supporters say repealing the waivers would stop a backdoor climate agenda without Congressional approval, while opponents warn it would weaken California’s authority under the Clean Air Act.
