California AB663 prohibits the sale and distribution of hydrofluorocarbons with certain global warming potentials, with exemptions for specific uses.

California AB663 amends the Health and Safety Code to restrict the sale and distribution of hydrofluorocarbons based on their global warming potential. Starting January 1, 2025, hydrofluorocarbons must not exceed a global warming potential of 2,200. This limit decreases to 1,500 by January 1, 2030, and further to 750 by January 1, 2033. Exemptions include reclaimed refrigerants, metered dose inhalers, and very low temperature refrigeration. The bill also mandates the state board to initiate rulemaking for low or ultra-low global warming potential alternatives unless impractical.
