Further amendments to the Montreal Protocol and the European F-gas Regulation aimed to replace the high-GWP F-gases with low-GWP alternatives . Nevertheless, the substances proposed as replacements -hydrofluoroolefins (HFOs) and even currently applied HFCsadd to the problem because many HFOs and HFCs can be either partially (e.g. HFC-134a, HFC-143a, HFC-1234ze, HCFO-1233zd) or completely (e.g., HFC-227ea, HFO-1225ye(E), HFO-1225ye(Z), u-HCFC-1224yd(Z) and HFO-1234yf) transformed to TFA . The use of HFO-1234yf was estimated to be responsible for 6900 t/year emissions of TFA in 2020 in the EU alone, with a potential increase in emissions up to 47,650 t/year by 2050 . This shift in Fgases could cause emissions of TFA to increase by orders of magnitude in the coming years , along with a corresponding contribution to climate impacts due to the formation of more fluoroform from TFA in the troposphere .
