Which of the following refrigerants has the least global warming potential?
A: HFC-23
B: HCFC-123
C: CFC-11
D: CFC-12

参考答案: B

本题解释:
HFCs have low ODPs but high GWPs.

While you don\'t need to memorize the entire table of ODP and GWP values, note that while HFCs deplete less ozone, HCFC-123 causes less global warming than any HFC.

CFC-11 and CFC-12 both have high GWPs.

CFC-11 and CFC-12 both have high GWPs.
