The U.S. Environmental Protection Agency (EPA) has finalized updates to its hydrofluorocarbon (HFC) regulatory program under the American Innovation and Manufacturing (AIM) Act, adjusting compliance procedures for companies involved in refrigeration, air conditioning, and industrial cooling systems.
What Happened
EPA has revised its HFC phasedown rules to improve implementation clarity and compliance efficiency. The update affects how companies track, report, and manage HFC usage across supply chains — with a long-term goal of gradually reducing high-GWP (global warming potential) refrigerants through 2036.
Phasedown Timeline
Compliance phases already in progress under the AIM Act phasedown schedule
EPA finalizes revised HFC tracking, reporting, and quota management procedures
Next phasedown reduction step affecting import/export quotas and refrigerant allocations
Gradual HFC reduction continuing toward near-full elimination of high-GWP refrigerants
What Changes in Practice
- Update refrigerant tracking systems
- Adjust import/export quota management
- Transition to low-GWP alternatives
- Improve reporting and recordkeeping
Who Is Affected
- HVAC manufacturers
- Refrigeration companies
- Chemical producers
- Importers of refrigerant gases
What Companies Should Do
- Review quota allocations under updated AIM Act rules
- Accelerate transition to alternative low-GWP refrigerants
- Strengthen compliance reporting and recordkeeping systems
- Monitor EPA phasedown schedule announcements
EPA’s updated HFC rules continue the long-term phasedown strategy under the AIM Act, requiring industries to accelerate the transition toward lower-emission cooling technologies and tighten compliance tracking.
