R-134a pojawił się na początku lat 90. XX w. jako zamiennik R-12, ze względu na jego szkodliwe działanie na warstwę ozonową. Przez ostatnie 10 lat zawartość 1,1,1,2-tetrafluoroetanu w atmosferze wyraźnie wzrosła, a w latach 2001–2004 podwoiła się.

R134a is a HFC, used in automotive air conditioning and as a replacement for R12 and R22 in medium and high temperature refrigeration applications, such as …

Contains 1,1,1,2-Tetrafluoroethane (HFC-134a), a greenhouse gas which may contribute to global warming. HFC-134a is a haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane), but with less ozone depletion potential. R-134a has the formula CH2FCF3. R134a är den mest vanliga köldmedia som används i en lång rad kyl- och luftkonditioneringsapplikationer, inklusive medelhög och hög temperatur (hushåll och kommersiellt), luftkonditionering i bostäder och lätt luftkonditionering, luftkonditionering i fordon samt industriella tillämpningar som t.ex.
