High increase of global F-gas emissions until 2050

Abstract

Emissions of fluorinated greenhouse gases (GHGs) (hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphurhexafluoride (SF6)) have increased significantly in recent years and are estimated to rise further. Banks and emissions of HFCs, PFCs and SF6 in the year 2050 are projected per sector in a business-as-usual scenario. The total global emissions of fluorinated GHGs will amount to 4 GT CO2 eq. by 2050 if no mitigation measures are taken. The contribution of F-gases to global warming will increase from approx. 1.3% (2004) to 7.9% of projected total anthropogenic CO2 emissions in this business-as-usual scenario in 2050. For significant reductions in future emissions of Kyoto F-gases, additional efforts from both developed and developing countries are needed.
