The figure shows the 100-year Global Warming Potential (GWPs) of CH₄ from the Intergovernmental Panel for Climate Change (IPCC) Assessment Report 2, 4 and 5 (AR2, AR4, AR5), together with the AR5’s 20-year GWP. The 100-year values are used to allow comparison with other greenhouse gases (GHGs) reported in the inventories and have been agreed by the Parties for reporting under the United Nations Framework Convention on Climate Change (UNFCCC), the Kyoto Protocol and the Paris Agreement.

Additional information

Source: EEA, based on the 2022 EU GHG inventory, and using the following IPCC GWPs for methane: AR2 (100-year)=21; AR4 (100-year)=25; AR5 (100-year)=28; AR5 (20-year)=84. 'AR' in the figure means 'IPCC Assessment Report', and 'GWP' means 'global warming potential'
