In May, Colorado Gov. Jared Polis signed into law the strongest state bill to date restricting the sale of PFAS "forever chemicals" in an array of consumer products and, for the first time, in the fluids used to extract oil and gas products (such as for hydraulic fracturing).

The law phases out the use of PFAS — known scientifically as perfluoroalkyl and polyfluoroalkyl substances — in carpets, upholstered furniture, fabric treatments, cosmetics, juvenile products, textile furnishings (draperies and tablecloths) and certain types of food packaging. It also requires any cookware with PFAS to be labeled. It does not allow for any exemptions, and it starts to take effect Jan. 1, 2024.
