Switzerland: annual greenhouse gas emissions of the energy sector 2022

The annual greenhouse gas emissions in the energy sector in Switzerland decreased by 2.9 million tons of CO2 equivalent (-8.52 percent) in 2022 in comparison to the previous year. This marks the lowest annual greenhouse gas emissions in this industry during the observed period.
The European Union (EU) as a party to the United Nations Framework Convention on Climate Change (UNFCCC) reports annually its greenhouse gas inventory for the year t-2 and within the area covered by its Member States. The inventory contains data on carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), perfluorocarbons (PFCs), hydrofluorocarbons (HFCs), sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3). The EU inventory is fully consistent with national greenhouse gas inventories compiled by the EU Member States.

Supplementary notes

According to the source, the annual greenhouse gas (GHG) emissions are estimated and reported under the United Nations Framework Convention on Climate Change (UNFCCC), the Kyoto Protocol and the Decision 525/2013/EC. The so called Kyoto basket includes six gases: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulphur hexafluoride (SF6). The impact of land use, land use changes and forestry (LULUCF) on the GHG inventories is excluded. International aviation is included. Emissions are weighted according to the global warming potential of each gas. To obtain emissions in CO2-equivalents using their global warming potential (GWP) the following weighting factors are used: CH4=25 and N2O=298, NF3=17200 and SF6=22800. HFCs and PFCs comprise a large number of different gases that have different GWPs .the annual greenhouse gas (GHG) emissions are estimated and reported under the United Nations Framework Convention on Climate Change (UNFCCC), the Kyoto Protocol and the Decision 280/2004/EC.
