Ozone depletion
The Antarctic ozone hole reaches its maximum extent in October of each year. On October 7, 2021, when this image was captured, the Antarctic ozone hole spanned 24.8 million square km (9.6 million square miles).
The Vienna Convention for the Protection of the Ozone Layer, adopted in 1985, was primarily intended to foster international cooperation regarding research into ozone-depleting chemicals.1
Rather than mandating specific regulatory measures or identifying particular substances to be controlled, the convention served as a foundational framework. Its key objectives included:2
- Promoting Research: Encouraging collaborative scientific efforts to better understand the impact of ozone depletion on human health and the environment.12
- Laying Groundwork: Empowering the United Nations Environment Programme (UNEP) to establish the necessary basis for future, more specific agreements, such as the Montreal Protocol.1
By design, the convention was flexible, allowing signatory states to adapt their policies as scientific understanding and technological capabilities evolved.2
