Fluorinated greenhouse gases (F-Gases) are a group of chemicals containing fluorine. The most common F-Gases are hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulfur hexafluoride (SF6). These are all man-made gases that are used in a variety of applications including refrigeration, foam blowing, propellants, aluminium and semiconductor manufacturing. During their use, these gases can be emitted to the atmosphere. However once released, many of these gases stay in the atmosphere for years and make a far greater contribution to a global greenhouse effect than carbon dioxide.
