Gaseous constituents of the atmosphere, both natural and anthropogenic, that absorb and emit radiation at specific wavelengths within the spectrum of radiation emitted by the Earth's ocean and land surface, by the atmosphere itself and by clouds. This property causes the greenhouse effect. Water vapour , carbon dioxide , nitrous oxide , methane  and ozone  are the primary GHGs in the Earth's atmosphere. Human-made GHGS include sulphur hexafluoride , hydrofluorocarbons , chlorofluorocarbons  and perfluorocarbons ; several of these are also 0₁-depleting .
