Fluorinated gases mentioned in the present study. The 100-year GWP was taken from the third version of the European F-gas Regulation,⁹ the percentages of TFA formation from Behringer et al. (2021).¹¹ The values for the HFCs for the 100-year GWP (GWP-100) in the third version of the European F-gas Regulation are from the fourth assessment report of the Intergovernmental Panel on Climate Change (IPCC) and are lower than the values for the 100 year GWP from the sixth assessment report of the IPCC.⁴⁵ These outdated (and lower) values were kept here to be in line with the F-gas Regulation and the thresholds set there.
