The Ozone Secretariat is based in Nairobi, Kenya, housed within the United Nations Environment Program (UNEP). It is the administrative office for two very important ozone protection treaties/agreements, the Vienna Convention for the Protection of the Ozone Layer and the Montreal Protocol on Substances that Deplete the Ozone Layer. Both play a major role in protecting the ozone layer and reducing the size of its hole.
The Ozone Secretariat organises conferences and meetings for the Vienna Convention and the Montreal Protocol, manages the implementation of decisions resulting from these conventions and meetings, provides stakeholders with data and information on the production and consumption of ozone depleting substances (ODSs) and provides governments, organizations and individuals with information on how they can protect the ozone layer as well.
