When were CFCs banned?
Solution
Chlorofluorocarbons (CFCs) were banned in 1996 under the Montreal Protocol. This international treaty was designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion. It was agreed upon on September 16, 1987, and has been revised and adjusted several times since. The ban on CFCs has been very successful, with nearly 100% compliance from all countries.
