About climate change: List of greenhouse gases
Note: The figures listed in the table below are the 1995 Global Warming Potential values. Whilst the GWP have since been updated, the Kyoto Protocol states that "global warming potentials used by Parties [to the Protocol] should be those provided by the Intergovernmental Panel on Climate Change in its Second Assessment Report ("1995 IPCC GWP values").".
