Overview

• President Trump signed three Congressional Review Act resolutions overturning EPA waivers that allowed California to set stricter vehicle emissions standards.
• California and ten other states filed suit in federal court, contending that using the CRA to remove their emissions authority is unprecedented and unlawful under the Clean Air Act.
• At least a dozen states that had adopted California’s clean car and heavy-duty truck rules will no longer be able to enforce zero-emission vehicle mandates or stringent tailpipe limits.
• Auto industry groups including General Motors and the Alliance for Automotive Innovation praised a uniform national standard, while environmental advocates warn the rollback could stall electric-vehicle adoption.
• Legal experts say the action fits a broader administration effort to undo climate safeguards, and during the signing ceremony the president hinted at raising tariffs on imported automobiles.
