Expanded HFC Data

The American Innovation and Manufacturing (AIM) Act directs EPA to phase down production and consumption of regulated hydrofluorocarbons (HFCs) in the United States by 85 percent from baseline levels by 2036. This phasedown is consistent with the U.S. schedule under the Kigali Amendment to the Montreal Protocol. To promote data transparency and accountability, this page includes detailed information on HFC production and consumption and HFC allowance activity. All reported data are certified by the reporter to be true, accurate, and complete. EPA continues to review and verify these data and may revise and update these data, as appropriate. Additional information on HFC production and consumption and HFC allowance activity is also available on the HFC Data Hub.

Data are current as of September 5, 2025.

This page provides the following information on HFCs for reporting year 2024:

• Production
• Consumption
• Production Allowance Activity
• Consumption Allowance Activity

HFC Production

The following table provides additional detail on the data used to calculate HFC production in the United States. HFC production is equal to the quantity of HFCs produced, excluding the quantity produced for feedstock, minus destruction.

Data elements included are defined as follows:

• Reported Production equals gross production.
• Production for Feedstock includes HFCs produced for U.S. feedstock use and exported for feedstock.
• Reported Destruction includes, e.g., in-house destruction by HFC producers, imported for destruction by the importer (i.e., in house), and destroyed by a second party.

HFC Production for 2024

Of the 18 HFCs regulated under the AIM Act, only those produced in 2024 are shown in the table.

HFC Consumption

The following table provides additional detail on the data used to calculate HFC consumption in the United States. HFC consumption is equal to production plus imports minus exports. Consumption is calculated in two different ways: 1) using calculations consistent with the AIM Act, which include imports and exports of used HFCs, and 2) using calculations consistent with reporting requirements under the Montreal Protocol, which do not include imports and exports of used HFCs.

Data elements included are defined as follows:

• Reported Production equals gross production.
• Production for Feedstock includes HFCs produced for U.S. feedstock use and exported for feedstock.
• Virgin Imports reflect imports of virgin HFCs that are not used as feedstock.
• Used Imports reflect imports of used HFCs that are not used as feedstock.
• Virgin Exports reflect exports of virgin HFCs that are not used as feedstock.
• Used Exports reflect exports of used HFCs.
• Reported Destruction includes, e.g., in-house destruction by HFC producers, imported for destruction by the importer (i.e., in house) and destroyed by a second party.

HFC Consumption for 2024

Due to rounding and continued data verification, the total consumption value could vary by up to 2% of the 2024 AIM Act consumption limit.

The waterfall chart below depicts the components of HFC consumption in the U.S. per the AIM Act definition. Production and imports of HFCs increase consumption. Feedstock use, exports and destruction lower consumption. The overall consumption cap for 2024 is indicated by the orange line. Hover over elements of the figure for more information.

HFC Production Allowance Activity

The following table provides additional detail on HFC production allowance activity data.

Data elements included are defined as follows:

• Number of Allowances Issued reflects allowances allocated for 2024.
• Transfers account for allowances transferred between entities in accordance with 40 CFR 84.19. Download the data, available at the top of the page, to find more detail on transfers.
• Imports reflect allowances expended by importing HFCs.
• Production reflects allowances expended by producing HFCs.
• Unused Allowances are allowances that were available to the entity as of December 31, 2024, but not used. Allowances are valid between January 1 and December 31 of a given year. They cannot be expended, transferred, or conferred after December 31 of the year for which they were issued.

HFC Production Allowance Activity for 2024

For more information on application-specific allowances, see Application-specific Allowance Allocations.

HFC Consumption Allowance Activity

The following table provides additional detail on HFC consumption allowance activity data.

Data elements included are defined as follows:

• Number of Allowances Issued reflects allowances allocated for 2024.
• Administrative Consequences/Acquisitions account for changes in allowance balances due to company acquisitions and administrative consequences that were applied to 2024 allowances. Adjustments to the balance of 2025 allowances due to actions in 2024 are not reflected in this table. Additional details on administrative consequences can be found on EPA's administrative consequences webpage.
• Requests for Additional Consumption Allowances account for additional consumption allowances issued in accordance with 40 CFR 84.17.
• Transfers account for allowances transferred between entities in accordance with 40 CFR 84.19. Download the data, available at the top of the page, to find more detail on transfers.
• Imports reflect allowances expended by importing HFCs.
• Production reflects allowances expended by producing HFCs.
• Unused Allowances are allowances that were available to the entity as of December 31, 2024, but not used. Allowances are valid between January 1 and December 31 of a given year. They cannot be expended, transferred, or conferred after December 31 of the year for which they were issued. Negative values in the unused allowances column occur when an entity has reported HFC consumption that exceeds the number of allowances available to the entity as of December 31 of that year after factoring in amounts allocated, allowances expended, and transactions throughout the year, such as requests for additional consumption allowances and transfers. Such negative values could result in EPA pursuing administrative consequences under 40 CFR Part 84 and enforcement action.
