The Montreal Protocol was adopted in 1987 and entered into force in January 1989. The Protocol aims to protect the ozone layer and abolish the consumption and production of chemicals that negatively impact the ozone layer. The chemicals regulated by the Protocol can be found in the annex of the treaty text and include predominantly halogenated hydrocarbons. The Protocol is governed by the annual Meeting of Parties and supported by the Ozone Secretariat.
