Vienna Convention for the Protection of the Ozone Layer

The Vienna Convention was created in response to advancements in the un­derstanding of ozone depletion and its impacts on human health and the en­vironment. It took effect in 1988 and was universally ratified in 2009. The Con­vention calls on Parties to promote cooperation via systematic observations, research and information exchange on the effects of human activities on the ozone layer and to adopt legislative or administrative measures to deal with activities likely to have adverse effects on the ozone layer. However, the Con­vention does not contain legally binding controls or targets.
