PARIS/NAIROBI, 14 September 2012 – Hailed as the most successful treaty in United Nations history – for achieving universal ratification and meeting its targets ahead of schedule – the Montreal Protocol on Substances that Deplete the Ozone Layer will celebrate its 25th anniversary on 16 September.

The Protocol, which has been ratified by 197 countries, has enabled reductions of over 98 per cent of all global production and consumption of controlled ozone-depleting substances.
