Chemicals Strategy for Sustainability Compliance Environment Hydrofluorocarbons HFCs Environmental Protection Agency EPA American Innovation and Manufacturing AIM


The U.S. Environmental Protection Agency (EPA) has issued a final rule under the American Innovation and Manufacturing (AIM) Act of 2020 that sets out how certain industries may continue to use hydrofluorocarbons (HFCs) in specific applications. This action is part of the broader effort to phase down HFCs, which are powerful greenhouse gases that contribute to climate change. 

 

What the Rule Does 

    • Reviews six applications that currently receive special allowances to use HFCs. 
    • Determines which of these applications will continue to be eligible for allowances. 
    • Updates the process for how industries can petition EPA to request eligibility for new applications in the future. 
    • Revises the allocation method for allowances from 2026 onward. 
    • Authorizes one company to produce regulated substances for export. 
    • Finalizes confidentiality rules for certain newly reported information. 

 

Key Takeaways for Businesses 

    • Priority Access: Only applications that meet EPA’s criteria will continue to receive allowances for HFC use. 
    • Future Petitions: Companies can request EPA to review new applications through a clear petition process. 
    • Allowance Allocations: New rules define how allowances will be distributed from 2026 onward, ensuring fairness and consistency. 
    • Compliance: Businesses must follow the updated Technology Transitions regulations relevant to their industry. 

 

Effective Date and Reference 

This rule takes effect on September 25, 2025.
