Topic 3e - The Vienna Convention and Montreal Protocol – an exemplar for international policy
The Vienna Convention for the Protection of the Ozone Layer is a Multilateral Environmental Agreement that was agreed upon at the Vienna Conference of 1985 and entered into force in 1988. It acts as a framework for the international efforts to protect the ozone layer. The Montreal Protocol lays out the legally binding reduction goals for the use of CFCs. It took place due to scientific research on the negative effect of CFCs on ozone in the 1970s and the discovery of the ozone hole in 1985.
The Montreal Protocol has been instrumental in phasing out the production and use of CFCs resulting in a slowed-down depletion of the ozone layer. Climate scientists studying three decades of ozone measurements from seven satellites see a positive trend in global recovery thanks to international efforts to curb ozone-depleting substances. It provides a stable framework that allows governments, industry, environmental groups and scientists and technical experts to work together to plan long-term research and innovation.
