Action Needed: Colorado Flip-Flops, Proposes Adoption of California's Emissions Rules

Colorado's Air Quality Control Commission (AQCC) has published a SEMA-opposed regulation that, if approved, would require the state to adopt California’s latest motor vehicle emissions laws through 2032 but stop short of banning the sale of new gas- and diesel-powered cars beginning in 2035. Colorado has historically followed California’s tailpipe laws.

Once an advocate for individual choice in automobile purchases, Colorado is now flip-flopping. While initially rejecting California's ban on new internal combustion engine vehicles by 2035, Colorado is now pushing for an 80% zero-emissions vehicle (ZEV) mandate by 2032. This change in direction raises concerns about consumer choice, affordability, and the future of the automotive aftermarket industry.
