Which statement best describes the refrigerant R-1234y?

• A. R-1234y has the highest GWP.
• B. R-1234y has the lowest GWP.
• C. R-1234y has the mid-range GWP.
• D. R-1234y has no GWP value.

Answer: (C)

Global warming potential shows how much heat a refrigerant traps in the atmosphere over a set time, usually relative to carbon dioxide. R-1234yf has a very low GWP—about 4—which is far lower than traditional refrigerants like R-134a (around 1430). That tiny GWP makes it the lowest-GWP option among common automotive refrigerants, not mid-range and not zero. So the statement that best describes R-1234yf is that it has the lowest GWP.
