Greenhouse Gases (GHGs)<span class=" width="600" />

Greenhouse Gases (GHGs)

Emissions that trap heat in the atmosphere, causing global warming. The main greenhouse gases are carbon dioxide (CO2), Methane (CH4), Nitrous Oxide (N2O), and fluorinated gases (synthetic greenhouse gases emitted from industrial processes, including hydrofluorocarbons, perfluorocarbons, and surfur hexafluoride).[1] The Climate Registry draft update to…
