Bill > AB663

This bill modifies California's existing regulations on hydrofluorocarbons (HFCs), which are greenhouse gases commonly used in refrigeration and cooling systems. The bill eliminates the previous exemption for reclaimed refrigerants and creates new, more specific exemptions for certain types of refrigerants. Specifically, it maintains existing global warming potential (GWP) limits that progressively become more stringent over time, dropping from 2,200 in 2025 to 750 in 2033, while creating targeted exemptions for specialized uses such as medical dose inhalers (until 2030) and extremely low-temperature refrigeration applications (until 2028). The bill also mandates that state-owned equipment cannot use HFCs with a GWP higher than 750 starting in 2025, with some exceptions for reclaimed refrigerants. Violations of these regulations can result in penalties deposited into the Air Pollution Control Fund. The bill is classified as an urgency statute, meaning it will take effect immediately, with the stated goal of encouraging the reuse of hydrofluorocarbons rather than their disposal, which aligns with broader environmental protection and climate change mitigation efforts.
