Persistent fluorinated greenhouse gases

The atmospheric concentration increases. It was 10 ppt in 2020.

Long-lived fluorinated greenhouse gases are characterized by a long atmospheric residence time and a global warming potential well above 5000 CO2 equivalents. They are not degraded in manageable periods of time, but accumulate in the atmosphere. Besides sulfur hexafluoride (SF6), nitrogen trifluoride (NF3) and fully fluorinated hydrocarbons (PFC), such as CF4 and C2F6, belong to this group of subs... read more
