Colorado passed first-in-the-nation legislation requiring warning labels on gas stoves in June 2025. These warnings are similar to what is required by cigarette labeling laws.
The required labels urge consumers to educate themselves about the air quality implications of indoor gas stoves and direct consumers to the Colorado Department of Public Health and Environment for information on the health impacts. This could have a substantial impact, as government agencies estimate that about one-third of Colorado’s households use gas as their primary cooking source.
