The indicator measures total national emissions (from both ESD and ETS sectors) of the so called ‘Kyoto basket’ of greenhouse gases, including carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and the so-called F-gases (hydrofluorocarbons, perfluorocarbons, nitrogen triflouride (NF3) and sulphur hexafluoride (SF6)) from all sectors of the GHG emission inventories. Estimated emissions from international aviation and maritime transport are excluded. The indicator is presented in two forms: as net emissions including land use, land use change and forestry (LULUCF) as well as excluding LULUCF. Using each gas’ individual global warming potential (GWP), they are being integrated into a single indicator expressed in units of CO2 equivalents. The GHG emission inventories are submitted annually by the EU Member States to the United Nations Framework Convention on Climate Change (UNFCCC)
