Hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6) and nitrogen trifluoride (NF3) are potent greenhouse gases (GHGs), collectively described as synthetic GHGs (SGGs).
SGGs are covered by Australia’s emission reduction targets under the Kyoto Protocol (2013-2020) and the Paris Agreement (2021-2030).
Both the Kyoto Protocol and the Paris Agreement are legally-binding instruments under the United Nations Framework Convention on Climate Change (UNFCCC). HFCs are used extensively in Australia, largely in air conditioning and refrigeration, initially as ‘ozone-friendly’ replacements for chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs).
Minor uses of HFCs in Australia are as aerosol propellants, including metered dose inhalers (MDIs), as foam blowing agents, solvents, in fire extinguishers and others.
