Colorado Gas Stove Label Law Blocked

Last Friday, a federal judge in Denver blocked the state of Colorado from enforcing a new state law requiring that retailers post air quality warnings on gas stoves.

U.S. District Court Judge S. Kato Crews issued a preliminary injunction against House Bill 1161, which was passed by the legislature earlier this year and signed into law by Colorado Governor Jared Polis.  It took effect August 6, 2025, and imposed fines up to $20,000 per violation.  The preliminary injunction means the law cannot be enforced until and unless the case goes through the full legal process and the state overcomes the lawsuit, which was filed by longtime NPGA ally, the Association of Home Appliance Manufacturers.
