CFCs were phased out, but a manufacturer proposes expanding use of HCFC refrigerants. How does the Montreal Protocol treat HCFCs?
A cooling company replaces a CFC refrigerant with an HFC. What ozone-related property made HFCs attractive substitutes?
The 2016 Kigali Amendment added a phase-down schedule for which group of CFC substitutes?
Why does an HCFC generally have less ozone-depleting potential than a CFC?
After CFC-12 use ended in new U.S. motor-vehicle air conditioners, which refrigerant became the common retrofit substitute?
Why did the Kigali Amendment phase down many HFCs even though they do not deplete ozone?
Use the graph. Compared with 1993, what does the 2020 atmospheric CFC-11 record show?
Satellite measurements show middle-stratosphere hydrogen chloride declining by about 0.5% per year. What does this measurement indicate?
Monitoring finds declining controlled ozone-depleting substances and recovery progressing in the upper stratosphere. What does this evidence support?

Why can CFC-12 emitted before its phase-out continue to delay ozone recovery?
Why do many ozone-depleting substances reach the stratosphere before breaking down?
Why can older refrigerators, foams, and fire-suppression equipment slow ozone recovery even after new CFC production is phased out?
