Refrigerant Regulations
Track HFC phasedown rules, F-gas restrictions, equipment GWP limits, refrigerant handling requirements and major transition dates across the United States, European Union, United Kingdom, Canada, Australia and Japan.
Kigali drives the direction — national rules determine the details
The Kigali Amendment to the Montreal Protocol established a global phasedown of hydrofluorocarbons, but it did not create one universal refrigerant ban or one worldwide implementation date.
Countries and regions translate the international commitment into their own quota systems, product restrictions, GWP thresholds, technician rules, leak-management requirements and equipment transition dates. That means the same refrigerant can have a different regulatory role in different markets.
Review Refrigerant DatabaseHFC supply is being reduced over time, while many jurisdictions also apply separate product- and equipment-specific restrictions. Existing equipment may often continue operating under rules that are different from those applied to new systems.
- Global HFC reduction framework
- Different national implementation schedules
- Separate new-equipment and existing-equipment rules
- Safety standards remain independent design requirements
Choose the market where your equipment will be used
Start with jurisdiction first. A refrigerant that meets one market's current GWP threshold may still face a different timeline, certification rule or equipment restriction elsewhere.
The U.S. framework restricts HFCs by technology sector and subsector rather than applying one blanket refrigerant ban.
- Residential/light-commercial AC and heat-pump products: GWP 700 from January 1, 2025.
- New residential/light-commercial split systems installed after January 1, 2026 generally must use refrigerant below GWP 700, subject to EPA transition provisions.
- VRF systems move to GWP 700 installation compliance from January 1, 2027.
- Cold-storage warehouses began an interim GWP 700 stage on July 27, 2026 before tighter 2032 limits.
EU F-gas policy combines quota reduction with detailed placing-on-the-market prohibitions for refrigeration, air-conditioning and heat-pump equipment.
- Split air-to-water systems ≤12 kW: GWP 150 threshold from January 1, 2027, subject to safety exceptions.
- Split air-to-air systems ≤12 kW: GWP 150 threshold from January 1, 2029.
- Split systems >12 kW: GWP 750 from 2029 and GWP 150 from 2033, subject to stated safety exceptions.
- Split systems ≤12 kW move toward restrictions on fluorinated greenhouse gases from January 1, 2035.
Great Britain operates its own F-gas framework. Northern Ireland can be subject to different arrangements, so the two should not be treated as one identical regulatory market.
- In Great Britain, new single-split systems containing less than 3 kg of F-gas cannot use refrigerants above GWP 750 from 2025.
- Technicians working on stationary RACHP equipment require appropriate F-gas qualifications for installation, service, leak checks and recovery.
- Sales of F-gas for servicing covered equipment require certification checks and recordkeeping.
- Always confirm whether the project is in Great Britain or Northern Ireland.
Canada implements Kigali through the Ozone-depleting Substances and Halocarbon Alternatives Regulations, including bulk-HFC consumption controls and product-specific measures.
- HFC phasedown began in 2019.
- Annual HFC consumption has been reduced 40% from baseline since January 1, 2024.
- The next federal step is a 70% reduction from baseline beginning January 1, 2029.
- The final scheduled step reaches an 85% reduction from baseline in 2036.
Australia manages its HFC transition primarily through a declining bulk-import quota, licensing and targeted equipment rules.
- The 2026–2027 HFC quota is 4.25 million tonnes CO₂-e per year.
- The national phasedown reaches 15% of baseline from 2036.
- RAC equipment cannot be charged with a refrigerant having a higher GWP than the refrigerant the equipment was designed to use.
- Small AC equipment and certain multi-head systems using refrigerant above GWP 750 are subject to import/manufacture restrictions.
Japan's framework places strong emphasis on proper management of fluorocarbons across commercial air-conditioning and refrigeration equipment throughout the equipment lifecycle.
- Commercial AC and refrigeration equipment owners have management obligations under the Fluorocarbon Emissions Control Act.
- The framework addresses leakage calculation and reporting.
- Filling and recovery activities are regulated.
- Reclamation, destruction and equipment disposal are part of the lifecycle-control system.
Refrigerant regulation is more than a GWP number
A compliant refrigerant decision may involve supply controls, equipment restrictions, technician qualifications, leak management and end-of-life obligations in addition to GWP.
HFC Quotas & Phasedown
Controls how much HFC can enter or be consumed in a market over time.
Equipment GWP Limits
Restrict refrigerants above a threshold in specific equipment categories.
New-Equipment Dates
Different manufacture, import, sale and installation dates can apply.
Leak Management
Some jurisdictions require inspection, containment, reporting or repair measures.
Technician Certification
Installation, service, recovery and refrigerant handling may require licensed personnel.
Recovery & Disposal
End-of-life rules can require refrigerant recovery, reclamation, destruction and records.

Regulation changes the role of a refrigerant — not just its GWP label
The regulatory outlook for a refrigerant depends on its GWP, the equipment type, the target market, safety classification and whether the project is new equipment, an existing system or a service application.
Its high GWP places R410A outside major new-equipment thresholds such as the U.S. 700-GWP residential/light- commercial HVAC route, while existing equipment can remain serviceable under separate rules.
Explore R410A →R32 fits below the current U.S. 700-GWP threshold in relevant HVAC subsectors, but EU timelines increasingly push selected equipment categories toward GWP 150 and later non-fluorinated routes.
Explore R32 →R454B is an important lower-GWP HVAC pathway in markets using the 700-GWP threshold, but it remains a fluorinated refrigerant and must still be evaluated against longer- term regional restrictions.
Explore R454B →Natural refrigerants reduce direct climate impact and can fit long-term transition strategies, but flammability, pressure, toxicity, charge limits and equipment architecture remain essential engineering constraints.
Explore Natural Refrigerants →A GWP below a regulatory threshold does not automatically make a refrigerant suitable, approved or code-compliant for every system. Verify equipment listing, safety class, charge limits, applicable product standards and local codes.
