Bill Overview

Analyzed Economic Effects

6 provisions identified: 2 benefits, 3 costs, 1 mixed.

New phased limits on HFC sales

The law limits bulk HFCs sold in California by GWP. The caps are 2,200 (starting January 1, 2025), 1,500 (January 1, 2030), and 750 (January 1, 2033). For blends, the limit uses the blend’s overall GWP. The Air Resources Board can set even lower limits. Key terms follow federal rules, and GWP uses IPCC values.

State equipment must use low‑GWP refills

Starting January 1, 2025, state‑owned or operated stationary equipment cannot be serviced with HFCs over GWP 750. Certified reclaimed refrigerant is allowed. This applies to leak top‑offs and other service work for state equipment.

Sectors must shift to low‑GWP options

The Air Resources Board must start rules to require low or ultra‑low GWP alternatives to HFCs by sector. The board can skip a sector only if using these alternatives is not practicable. Businesses in covered sectors need to plan for replacements.

Inhaler HFCs stay allowed until 2030

HFCs used only in FDA‑approved metered dose inhalers are exempt from the sale ban. This medical exemption ends on December 27, 2030. Patients and makers can keep using these inhalers until then.

Temporary exemptions for niche refrigerant uses

Certified reclaimed refrigerant is exempt if it is reclaimed by an EPA‑certified reclaimer, meets federal Appendix A specs, and is no more than 15% new HFC by weight with documentation. HFCs used only in very low‑temperature equipment below −58°F (−50°C) are exempt until January 1, 2028. Examples include medical and lab freezers, specialized industrial cooling, and extreme temperature testing.

Fines and court orders for HFC violations

Breaking these HFC rules can lead to court injunctions and fines under existing state penalty laws. All penalties from these cases go to the Air Pollution Control Fund. Businesses should keep records and check product GWPs to avoid penalties.
