Global Emissions of Substitutes for Ozone Depleting Substances

The emissions of hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs) used as substitutes for ozone-depleting substances (ODS) are rising worldwide. EPA and various industries are working together to measure, manage, and reduce these emissions (e.g., through EPA partnerships).

Under the United Nations Framework Convention on Climate Change (UNFCCC), many nations including the United States, annually submit greenhouse gas emissions inventories that estimate emissions of HFCs, PFCs, and other greenhouse gases.
