Emissions of fluorinated greenhouse gases (F-gases)

Note:
The figure shows the emissions of hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulphur hexafluoride (SF₆) and nitrogen trifluoride (NF₃). Emissions are represented as million tonnes (Mt) CO₂ equivalent using the global warming potential (GWP) values of the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4).
