 Greenhouse Gases and Their Global Warming Potential
Relative to CO2
The global warming potential is an index that represents the combined
effect of the differing times greenhouse gases remain in the atmosphere
and their relative effectiveness in absorbing outgoing infrared radiation. The
index approximates the time-integrated warming effect of a unit mass
of a given greenhouse gas in today's atmosphere, relative to carbon
dioxide.
The chart below list commonly recognized greenhouse gases and their
global warming potential.
