HFC Policies & Refrigerant Regulations By State
In the U.S., the federal government and several states have enacted legislation to regulate Hydrofluorocarbon refrigerant (HFC) use and production. This interactive map tracks the regulatory status of each state. More information on each state is available below.
How to Use This Map
All of the colored states are part of the US Climate Alliance. Click on a state to learn more about its regulatory status. See the summaries by state below for more details.
+ US Climate Alliance Member
The state is a member of the US Climate Alliance, a coalition of states committed to upholding the Paris Climate Agreement’s goal of keeping temperature increases below 1.5 degrees Celsius. However, the state has not committed to regulating HFC refrigerants.
+ SNAP 20/21 Pending
The state has expressed intentions to introduce legislation to reduce HFC emissions, but no bills have been signed into law.
+ SNAP 20/21 Signed Into Law
The state has enacted legislation that prohibits certain HFCs in specific stationary refrigeration and air-conditioning end-uses in alignment with the federal EPA SNAP Rules 20 and 21.
+ SNAP Plus Additional GWP Limits
In addition to enacting legislation prohibiting certain HFCs in specific stationary refrigeration and air-conditioning end-uses, the state has enacted stricter regulations aimed at curbing HFC emissions beyond EPA SNAP Rules 20 and 21.
The HFC Problem
Hydrofluorocarbon refrigerants (HFCs) are greenhouse gases commonly used in refrigeration. Pound for pound, these super-pollutants trap thousands of times more heat in the atmosphere than carbon dioxide.
Once considered a suitable replacement for ozone-depleting substances, HFCs are now the world’s fastest-growing greenhouse gases. Scientists estimate that HFCs alone could contribute to up to 0.5°C of global warming by the end of the century.
What is SNAP?
Established under the Clean Air Act, the Environmental Protection Agency’s (EPA) Significant New Alternatives Policy (SNAP) program identifies and evaluates substitutes for ozone-depleting substances by end-use. SNAP Rules 20 and 21 list specific HFC refrigerants as unacceptable and identify acceptable alternatives.
The SNAP rules were vacated at the federal level in 2017 after a lawsuit claimed that the EPA had exceeded its statutory authority (Mexichem Fluor, Inc., v. EPA). In response, member states of the US Climate Alliance began adopting SNAP Rules 20 and 21 at the state level.
In 2020, the SNAP rules were partially reinstated and currently prohibit certain substitutes when switching from ozone-depleting substances.
Federal Regulations
+ American Innovation and Manufacturing (AIM) Act
Enacted in late 2020, the American Innovation and Manufacturing (AIM) Act directs the EPA to address HFC emissions through three main legislative activities:
- Phase down the production and consumption of HFCs in the United States by 85% by 2036, mirroring the Kigali Amendment. Learn more about the phasedown schedule, allowance allocations, and final allocations rule here.
- Facilitate the transition to next-generation technologies, implement restrictions on specific HFC uses, and approve substitutes for regulated HFCs. In December 2022, the EPA released a proposed rule in which the food retail sector would be limited to products >300 GWP by January 1, 2025. Some food retail applications - such as stand-alone units, refrigerated food processing & dispensing equipment, and supermarket systems or remote condensing units with refrigerant charges of 200lb or more – would be limited to >150 GWP by the same date. Read more here.
- Establish regulatory requirements for the management of refrigerants, including refrigerant reclamation and equipment servicing, repair, disposal, or installation. This portion of the rulemaking is in progress. Read more here.
+ Clean Air Act: Section 608
Section 608 of the Clean Air Act was established to prohibit intentional venting of ozone depleting refrigerants (CFCs and HCFCs) and their substitutes (HFCs) while maintaining, servicing, repairing, or disposing of air-conditioning or refrigeration equipment. Section 608 includes requirements related to:
- Technician Certification
- Refrigerant Recovery & Equipment Recycling
- Refrigerant Leaks
- Refrigerant Sales Restriction
- Recordkeeping
- Safe Disposal
- Reclamation
- Service Practices

Summary by State
+ California
In alignment with the federal EPA SNAP Rules 20 and 23, California enacted SB 1013, prohibiting certain HFCs in specific stationary refrigeration and air-conditioning end-uses.
Supermarket Effective Date: January 1, 2019
The state also approved new regulations requiring specific Global Warming Potential (GWP) thresholds for new and existing food retail facilities.
- New Facilities: California food retailers may not use refrigerants above 150 GWP in new facilities with systems containing more than 50 pounds of refrigerant starting January 1, 2022. New facility requirements apply to any of the following conditions:
- New construction
- An existing facility not previously used for cold storage, retail food refrigeration, commercial refrigeration, industrial process refrigeration or ice rinks
- An existing facility used for cold storage, retail food refrigeration, commercial refrigeration or industrial process refrigeration that has undergone replacement of 75% or more of its evaporators (by number) and 100% of its compressor racks and condensers
- Existing Facilities: California food retailers must meet one of the following GWP reduction targets across their existing facilities by 2030:
- Attain a companywide weighted average GWP1 of less than 1,400
- Attain a 55% or more significant reduction in Greenhouse Gas Potential (GHGp)2 below 2019 levels by 2030
Companies operating more than 20 facilities in California must also attain either a companywide weighted average GWP of less than 2,500 or a 25% or greater reduction in GHGp below 2019 levels by December 31, 2026.
Supermarket Effective Date: January 1, 2022
1. "Weighted-average GWP” is equal to ∑ (charge x GWP)/ ∑ charge
2. “Greenhouse Gas Potential” or “GHGp” is equal to Σ (Charge × GWP)
In August 2022, the state also passed SB 1206, which:
- Prohibits the sale, distribution, or otherwise entering into commerce in the state, bulk HFCs or HFC blends that exceed the following GWP thresholds:
- <2,200 data-preserve-html-node="true" beginning January 1, 2025
- <1,500 data-preserve-html-node="true" beginning January 1, 2030
- <750 data-preserve-html-node="true" beginning January 1, 2035
- Prohibits HFCs >750 GWP that are not reclaimed from being used to replenish leaks or otherwise service stationary equipment owned or operated by the state, beginning January 1, 2025.
- Directs CARB to do the following:
- Initiate a rulemaking requiring low and ultra-low global warming potential alternatives to HFC in a sector unless it is not practicable.
- Publish an assessment by January 1, 2025, which will specify how to transition the state’s economy away from HFCs and to ultra-low or no GWP alternatives no later than 2035.
