Decision IX/10: Ratification of the Vienna Convention, Montreal Protocol and London and Copenhagen Amendments

The Ninth Meeting of the Parties decided in Dec. IX/10:

  1. To note with satisfaction the large number of countries that have ratified the Vienna Convention for the Protection of the Ozone Layer and the Montreal Protocol on Substances that Deplete the Ozone Layer;
  2. To note that many Parties have yet to ratify the London and Copenhagen Amendments to the Montreal Protocol;
  3. To urge all States that have not yet done so, to ratify, approve or accede to the Vienna Convention, the Montreal Protocol and its Amendments, taking into account that universal participation is necessary to ensure the protection of the ozone layer.
