HFC Data Hub

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. To promote data transparency and accountability, this page includes information on the following information on HFCs for 2024:

• Production and Consumption
• Imports into the United States
• Allowance Allocations and Expenditures
• End-of-Year Inventory
• HFC-23 Emissions
• Reclamation

Additional information on HFC production and consumption and HFC allowance activity is also available on the Expanded HFC Data webpage. There is also access to the HFC Data Hub for prior years.

HFC Production and Consumption

Since January 1, 2022, the amount of HFC production and consumption allowed in the United States has been limited through an allowance allocation program. The figures and table below summarize production and consumption of regulated HFCs based on activity data reported under 40 CFR Part 84. Production is equal to the amount of a regulated substance manufactured from a raw material or feedstock chemical (excluding the amount produced for feedstock) minus destruction. Consumption is equal to production plus imports minus exports.

production = gross production - production for feedstock - destruction

consumption = production + imports - exports

The current data reported to EPA as of September 5, 2025, are shown below. All reported data are certified by the reporting entity to be true, accurate, and complete. EPA continues to review and verify these data and may revise figures shown on this website as appropriate. Values are presented in metric tons (MT) or metric tons exchange value equivalent (MTEVe) using the exchange values included in subsection (c) of the AIM Act. In charts below, EPA also uses metric tons carbon dioxide equivalent (MTCO₂e). One MTEVe is numerically equivalent to one MTCO₂e.

HFC Production and Consumption Relative to the Phasedown Limit

The following figures depict the calculated level of HFC production and consumption relative to the AIM Act HFC phasedown schedule.¹ 

HFC Production and Consumption for 2024

The following table and pie charts depict production and consumption for 2024 aggregated by chemical, using calculations consistent with the AIM Act. Find more detail on production and consumption on the Expanded HFC Data webpage.

NA = Not Applicable.
Negative values occur when destruction exceeds production.
Of the 18 HFCs regulated under the AIM Act, only those produced or consumed in 2024 are shown in the table.
Due to rounding and continued data verification, the total consumption value could vary by up to 2% of the 2024 AIM Act consumption limit.

HFC Imports Into the United States for 2024

The following figures summarize the total quantity of imports into the United States in 2024. All bulk HFC imports into the United States are shown, including those for: consumptive use, feedstock use, destruction and application-specific uses.

The map below depicts the amount of regulated HFCs imported into the United States. The majority of these data were compiled from EPA’s HFC and ODS Allowance Tracking (HAWK) system. In a small number of cases, EPA included additional import information derived from U.S. Customs and Border Protection systems in calendar year 2024. The largest points of export were China (57%), India (26%) and the United Arab Emirates (7%). Hover over elements of the map for more information.

HFC Allowances Allocated and Expended

To phase down production and consumption of HFCs in the United States, EPA has established a methodology for allocating HFC production and consumption allowances under the authority of the AIM Act. The figure below shows consumption allowance expenditure for 2024 based on reported data. Allowances are presented on an exchange value (EV)-weighted basis.

Application-specific allowances are included in the above graphic. "Transfer offsets" refers to allowances retired during the transfer of allowances between entities. See 40 CFR 84.19(a)(1).

The tables below present the information summarized by the graphic above in greater detail. Consumption and production allowances allocated to each entity for 2024 are shown. The tables also summarize each entity’s unused allowances.²

HFC Production Allowance Activity for 2024

Find more detail on production allowance activity on the Expanded HFC Data webpage.

In some cases, entities may appear in the table as having unused allowances, even though they were not issued allowances. These entities received allowances via inter-entity transfers.
For more information on application-specific allowances, see Application-specific Allowance Allocations.

HFC Consumption Allowance Activity for 2024

Find more detail on consumption allowance activity on the Expanded HFC Data webpage.

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.
In some cases, entities may appear in the table as having unused allowances, even though they were not issued allowances. These entities received allowances via inter-entity transfers.
For more information on application-specific allowances, see Application-specific Allowance Allocations.

HFC End-of-Year Inventory

The following table and column chart summarize the total quantity of each regulated HFC reported as held in inventory by HFC producers, importers, exporters, fire suppression agent recyclers and reclaimers, as of December 31, 2024.

HFC End-of-Year Inventory for 2024

Totals in the table above sum the total reported inventory from 2024 HFC Quarterly Importer Reports, except in cases where the entity submitted HFC Quarterly Reclaimer Reports. If Quarterly Reclaimer Reports were available, EPA used inventory totals from those reports. If an entity neither imported nor reclaimed HFCs, inventory totals were taken from HFC Quarterly Producer Reports.
NA = Not Applicable.

HFC-23 Emissions

The following table summarizes the total quantities of HFC-23 generated and emitted per chemical manufacturing facility. Based on reported data for 2024, the ten chemical manufacturing facilities listed below met the 0.1 percent emissions standard.

HFC-23 Emissions for 2024

The 0.1 percent emissions limit for HFC-23 found in 40 CFR 84.27 is calculated by dividing the amount of reported HFC-23 emissions resulting from creation on each facility line by the amount of chemical intentionally produced on that line. For example, if HFC-23 is created on a line producing HCFC-22, compliance with the emissions limit would be calculated by dividing the total quantity of HFC-23 emitted by the total quantity of HCFC-22 produced on the same line. The table shows the amount of HFC-23 emissions reported to EPA, but neither information on the quantity of chemical that was intentionally produced on each facility line nor the calculated percent of HFC emissions per 40 CFR 84.27 is shown in this table.

HFC Reclamation

The following table depicts the reported total quantity of HFC received by reclaiming entities. For more information on reclamation, see Section 608 under the Clean Air Act and subsection (h) of the AIM Act.

HFC Reclamation for 2024

¹ The HFC phasedown schedule is relative to the production and consumption baselines, which are set out in 40 CFR 84.7.

² 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.
