HCFC-22 is

• A. An ozone-depleting substance and greenhouse gas.
• B. A renewable energy source.
• C. A non-ozone-depleting refrigerant.
• D. A solid fuel.

Answer: (B)

HCFC-22 is an ozone-depleting substance and greenhouse gas. It’s a hydrochlorofluorocarbon used as a refrigerant, and its chlorine content means that when it breaks down in the atmosphere, chlorine radicals can destroy ozone molecules, reducing the ozone layer’s protective capability. It also traps heat in the atmosphere, giving it a significant global warming potential. It is not a renewable energy source, nor a non-ozone-depleting refrigerant, nor a solid fuel. It’s a synthetic refrigerant whose environmental drawbacks have led to regulatory phase-downs and a move toward alternatives with lower ozone depletion and global warming impacts.
