Greenhouse Gases (GHG)
Greenhouse gases (“GHG”) are gases that store and emit radiant energy in the thermal infrared range, which leads to the “greenhouse effect” by heating up the atmosphere and thus contributing to global warming. The main greenhouse gases associated with man-made global warming are: carbon dioxide (CO₂), methane (CH4), nitrous oxide (N₂O), hydrofluorocarbons (HFC), perfluorocarbons (PFC) and sulfur hexafluoride (SF6).
