Stop CARB Act of 2025

# Stop CARB Act of 2025 Summary **What the Bill Would Do:** The Stop CARB Act of 2025 (HR 2218) is a bill introduced in the House of Representatives that would address California's vehicle emission standards and their national impact. CARB refers to the California Air Resources Board, which sets stricter vehicle emission rules than federal standards. Under current law, California can set its own vehicle pollution rules, and other states can choose to follow California's standards instead of federal ones. This bill would limit or eliminate that authority, preventing California from setting emission standards that differ from federal levels. **Who It Affects & Key Provisions:** The bill primarily affects automakers, who would no longer need to produce different vehicle models to meet California's stricter standards—they could manufacture one set of vehicles meeting only federal requirements.

It would also affect consumers in California and other states that have adopted California's emission standards, potentially limiting access to lower-emission vehicle options. Environmental advocates would likely oppose it, while some industry groups argue it could reduce manufacturing costs. **Current Status:** The bill is currently in committee, meaning it has been introduced but has not yet been debated or voted on by the full House. It was sponsored by Representative Troy E. Nehls (R-TX).
