A greenhouse gas absorbs and emits infrared radiation at the wavelengths of the radiation emitted by the Earth’s surface, and so warms the lower atmosphere. The global warming potential (GWP) of a gas over a time horizon, usually 100 years, is the energy it traps after the emission of one kilogram, relative to one kilogram of carbon dioxide.
