Fluorinated gases are a group of synthetic gases that contain fluorine. They are used in various applications, including refrigeration, air conditioning, and insulation. These gases are known for their ability to trap heat in the atmosphere, making them potent greenhouse gases. There are several types of fluorinated gases, including hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). While they are effective in their intended uses, their long atmospheric lifetimes contribute to climate change, prompting efforts to reduce their emissions through international agreements like the Montreal Protocol.
