R134a is a fluorocarbon and contains no chlorine.
R134a has a shorter atmospheric life span than refrigerant R12.
R134a does not damage the ozone layer. The ozone depletion potential is zero.
The greenhouse potential of R134a (Global Warming Potential = GWP) is approximately 1430 (the GWP of carbon dioxide is 1).
The global warming effect of R134a is ten times less than that of refrigerant R12.
