   HFO-1234yf was developed by a team at DuPont, led by Barbara Haviland Minor, jointly with researchers at Honeywell. [8] [9] Their goal was to meet European directive 2006/40/EC, which went into effect in 2011 and required that all new car platforms for sale in Europe use a refrigerant in its AC system with a global warming potential (GWP) less than 150 times more potent than carbon dioxide.

   1,1,1,2-Tetrafluoroethane (also known as norflurane (), R-134a, Klea 134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, HFA-134a, or HFC-134a) is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion potential and a lower 100-year global warming ...

6. Freon - Wikipedia

   en.wikipedia.org/wiki/Freon

   'Freon' is the brand name for the refrigerants R-12, R-13B1, R-22, R-410A, R-502, and R-503 manufactured by The Chemours Company, and so is not used to label all refrigerants of this type. They emit a strong smell similar to acetone. [2] Freon has been found to cause damage to human health when inhaled in large amounts.
