    1987

    Explanation:

    The depletion of the ozone layer and the antarctic ozone hole made a danger for the humans to survive on the planet. Depletion of the ozone from the continued use of CFCs can cause skin cancer and many problems which dragged international action to be implemented.

    Thus, in 1987, around 56 countries agreed the Montreal Protocol which states the CFC production to cut and also reduction of its use to half.

    After few years, this protocol was more strengthened to stop the worldwide production of CFCs and also other chemicals which depletes ozone layer.
