Gas Stoves Being Sold In Colorado Now Come With A Warning. Here's What To Know

Consumers who shop for a gas range or stove for their kitchen in Colorado will now see a consumer health warning alongside the appliance's product details. The change is part of House Bill 25-1611, which requires retailers to include a notification in English and Spanish about the health impacts of indoor gas stoves. Signed by Governor Jared Polis in May 2025, it's now in effect to guide consumers toward an informed decision after considering the potential downsides of gas stovetops. However, an appliance trade association is asking for court intervention.

HB 25-1611 specifies a "yellow adhesive label must appear on the display model for a gas-fueled stove," and a similar warning must appear on online product listings if "transacting in the state." The label must also include a link or QR code to a Colorado Department of Public Health and Environment webpage stating evidence-based facts of gas on consumer health. Colorado is the first state to officially enact such a requirement. Legislators proposed a similar measure in California in 2024, but Governor Gavin Newsom vetoed it, on the basis it was too restrictive. Now the Colorado law faces a Free Speech lawsuit by the Association of Home Appliance Manufacturers (AHAM). On August 5, AHAM filed an emergency motion for a temporary restraining order and preliminary injunction to stop enforcement of the law. In the brief, AHAM claims that the labels warn consumers of "unproven health effects" and the requirement is "unconstitutional compelled speech." It states there's no "association between gas stoves and adverse health outcomes," and requests the United States District Court of Colorado pause the law's enforcement until it can go to court.

An issue at the core of AHAM's lawsuit is the fines retailers face if they don't follow the labeling requirement. According to the bill, retailers in violation commit a deceptive trade practice under the Colorado Consumer Protection Act. The Act, updated in 2019, levies a fine of $20,000 per violation, an amount AHAM deems excessive. In a statement, Kelly Mariotti, President and CEO of AHAM said, "We strongly support science-based practices that protect consumers. What we are opposing is a state government compelling private companies to communicate a message that lacks scientific consensus. [...] If the labeling requirement remains in place, Coloradans may be persuaded to make decisions based on incomplete and unproven information." (via Morningstar).

The District Court hasn't set a hearing date, and a spokesperson for the Colorado Attorney General's Office declined to comment on the lawsuit. On its webpage, Colorado shares information about the possible harm gas stoves can cause. The information regards the gas' effect on indoor air quality and ways consumers can mitigate the effects. Sources for the information page include the Centers For Disease Control and Prevention (CDC), the U.S. Environmental Protection Agency (EPA), and assorted health studies.

Health effects listed include nausea, headaches, irritation of the eye, nose, or throat, and respiratory symptoms. This ongoing research has some considering getting rid of their gas stove, but despite the known effects, Grand View Research experts project the gas cooking industry will grow by 7% in 2025. For now, consumers in Colorado can inform themselves of the potential dangers associated with indoor gas and make a decision based on their needs.
