Vienna Convention (1985)

The Vienna Convention for the Protection of the Ozone Layer is a framework convention, which served as a scheme to support the efforts on protecting the ozone layer. It was adopted in 1985 and entered into force in 1988. In 2009, the Vienna Convention became the first Convention of any kind to achieve universal ratification. The Convention aims at the promotion of cooperation by the Parties by means of systematic observations, research and information exchange on the effects of human activities on the ozone layer. Moreover, another objective of the Convention is the Parties’ adoption of legislative or administrative measures against activities likely to have adverse effects on the ozone layer.

The Vienna Convention did not require countries to take concrete actions to control ozone depleting substances. According to the provisions of the Convention, the countries of the world agreed on the Montreal Protocol on Substances that Deplete the Ozone Layer under the Convention to reach that goal.

The Parties to the Vienna Convention meet once every three years, back to back with the Parties to the Montreal Protocol, in order to take decisions designed to execute the Convention.

Montreal Protocol

The Montreal Protocol on Substances that Deplete the Ozone Layer was conceived to reduce the production and consumption of ozone depleting substances in order to diminish their abundance in the atmosphere, and to protect the earth’s ozone Layer. The original Montreal Protocol was agreed on 16 September 1987 and entered into force on 1 January 1989. Since its initial adoption, the Montreal Protocol has been adjusted six times.

The Parties to the Montreal Protocol have amended the Protocol to enable the control of new chemicals and the creation of a financial mechanism that enables developing countries to comply.

Besides the adjustments and amendments to the Montreal Protocol, the Parties to the Protocol meet annually and take decisions aimed at enabling effective implementation of this important legal instrument. The decisions adopted by the Parties are included in the reports of the Meetings of the Parties and, along with other documents, considered during the meetings.
