2. 2,3,3,3-Tetrafluoropropene - Wikipedia

   en.wikipedia.org/wiki/2,3,3,3-Tetrafluoropropene

   R-1234yf is also a component of zeotropic refrigerant blend R-454B. HFO-1234yf has a GWP less than carbon dioxide , [ 4 ] [ 2 ] itself 1,430 times less potent than R-134a . [ 5 ] For this reason, 2,3,3,3‑tetrafluoropropene is the pre-eminent replacement for R-134a in vehicular air conditioners .
