The Montreal Protocol is a global agreement to protect the planet’s ozone layer by phasing out chemicals that deplete it. This landmark agreement entered into force in 1989 and is one of the most successful global environmental agreements. Thanks to the collaborative efforts of countries around the world, the ozone layer is on the way to recovery and many environmental and economic benefits have already been achieved.
terms and objectives of this Treaty
The treaty revolves around several groups of halogenated hydrocarbons that have been shown to play a role in the depletion of the ozone layer. All of these ozone depleting substances contain either chlorine or bromine (only fluorine-containing substances do not harm the ozone layer).
The treaty provided a timetable for the phasing out and eventual elimination of production of each group of substances.
