Context	● 1973 • scientists discovered that CFCs were thinning the ozone layer ∴ increasing people's exposure to harmful UV radiation from the sun ● The Montreal Protocol on substances that deplete the ozone layer was negotiated by the UN over 14 yrs and came into force in 1989 ● In 1977 'World Plan of Action on the Ozone Layer' gave the UNEP responsibility for promoting and co-ordinating international research and data-gathering activities The Montreal Protocol is an example of successful IG management of a global environmental problem.
The Protocol	● Phased out the production of CFCs ● It was approved by 197 countries ○ Within a decade, irrefutable proof that CFCs were to blame led to all UN states signing the treaty • allowed CFCs to be phased out rapidly due to the level of international cooperation
