CFCs were one of the most useful class of

compounds ever developed because of their chemical stability,

non-inflammability, non-corrosiveness and low toxicity.

CFCs were developed as a safe alternative to

Freon-11

Inertness and stability of CFCs facilitate the depletion

of ozone layer

According to the Montreal protocol, countries

producing ODS > 300 mg/capita/year need to fund the fight against the O

depletion
