What is the main issue with HFCs?

Explanation:
HFCs were developed to avoid ozone depletion, so they have essentially zero ozone-depletion potential. The real concern with them is their global warming potential, which is extremely high—often thousands of times that of CO2 over a 100-year period. This means that even small leaks or releases from refrigeration and air-conditioning systems can have a large impact on climate. Because of this, regulators focus on reducing HFC use and switching to lower-GWP or more efficient alternatives. The statements suggesting they have low environmental impact or do not affect climate miss the point, since their main issue is their strong warming effect.
