California’s AB 32 requires a reduction in statewide GHG emissions, including HFCs, to 1990 levels, by 2020 (this target was strengthened by SB 1383 in 2016 to a 40% reduction in GHGs below 1990 levels by 2030). AB 32 tasks the California Air Resources Board with developing scoping plans with regulations or nonregulatory measures. CARB’s 2014 scoping plan identifies a number of actions to reduce HFC emissions, which has been the basis of several subsequent regulations elsewhere in this section.
