Greenhouse gases (GHGs) are natural and industrial gases that trap heat from the Earth and warm the surface.
The Kyoto Protocol restricts emissions of six greenhouse gases: natural (carbon dioxide, nitrous oxide, and methane) and industrial (perfluorocarbons, hydrofluorocarbons, and sulphur hexafluoride).
