The UN Environment Programme states, “The ultimate objective of the Convention is to protect human health and the environment against adverse effects resulting from human activities which modify or likely to modify the ozone layer and urges the Parties to take appropriate measures in accordance with the provisions in the Convention and its Protocols which are in force for that Party.”
The convention was adopted on March 22,1985 and entered into force on September 22,1988. It does not include legal obligations to reduce the use of CFCs and other ozone –deleting substances; this is stipulated in the Montreal Protocol.
