The Secretary-General Message on The International Day for the Preservation of the Ozone
“Ozone layer protection: governance and compliance at their best.”
This year, the International Day for the Preservation of the Ozone Layer high lights the central role of good governance in pursuit of environmental goals. Ingeneral, successful environmental agreements require a broad framework, clear targetsand a gradual approach to implementation. Then, as governments gain confidence, they build on initial steps and set more ambitious goals. The Montreal Protocol on Substances that Deplete the Ozone Layer – which last year achieved universal ratification – is an excellent example of this process.When the Montreal Protocol was signed in 1987, governments did not original lyenvision the phase-out of any ozone-depleting substance. Yet, as a resultv of very strongnational and global compliance, Parties to the Montreal Protocol have cut the productionand consumption of more than 98 per cent of these harmful chemicals. In the process, the Protocol has also reduced emissions of greenhouse gases by more than 135 billion tons of CO2 equivalent, making it instrumental in the fight against climate change.
The Montreal Protocol could not have delivered such profound achievements without robust governance and compliance structures put in place by its Parties, both collectively and individually. The foundation of the Protocol is fairness. Through the principle of “common but differentiated responsibility”, the treaty provides a grace period to developing country parties, a funding mechanism governed by an equitable representation of developing and developed countries, compensation for the cost ofphasing out ozone-depleting chemicals, capacity building for national ozone offices in 147 developing countries, and dissemination of the most up-to-date ozone-friendly technologies.
I encourage Parties to the Montreal Protocol to continue to build on this modeland to explore synergies that could help to address other environmental challenges,especially climate change. Let us use the governance tools contained in the existingozone and climate treaties to reduce environmental threats to sustainable development and human well-being.
