Preserves preexisting federal regulations on the use of hydrofluorocarbons in state law. Phases out hydrofluorocarbons in favor of alternatives with lower global warming potential. Establishes a preference for products that do not contain hydrofluorocarbons in the state procurement code. Directs the State Energy Office and the Environmental Management Division of the Department of Health to study how to increase the use of refrigerants with low global warming potential, reduce the use of hydrofluorocarbons, and recommend how to fund, structure, and prioritize a state program that incentivizes or provides grants to support the elimination of legacy uses of hydrofluorocarbons.
