Opinio Juris has a fantastic post regarding the Montreal Protocol on Substances that Deplete the Ozone Layer‘s September 16 birthday. According to the post:
The Protocol has aged well, frequently celebrated as the most successful international environmental treaty. It has effectively phased out or controlled the production and consumption of most ozone depleting substances that threaten the ozone layer. In the process, scientists have estimated millions of human lives have been or will be saved from skin cancer and its potentially deadly consequences (not to mention avoiding severe degredation of fisheries, flora and fauna via harmful UV rays that the ozone layer mitigates here on earth). The states parties to the treaty are planning a day of celebration to mark the occasion as well as the commencement of the 19th Meeting of the Parties.
And there is something to celebrate here. In terms of combating the problem itself, Montreal has worked out well so far. Although the ozone hole is now as large as it’s ever been, scientists estimate that over the next 50-75 years, the ozone layer will return to earlier levels. Moreover, the Montreal Protocol’s legal framework offers a model for interstate cooperation in responding to global environmental problems. The treaty has proved more than capable in allowing states to adjust their commitments in light of changes to scientific knowledge.
In light of the repeated beatings international treaties have taken over the past six years, let’s take today to celebrate a shining example of bipartisan, multinational cooperation. Happy birthday, Montreal Protocol!
