Thursday 17 March 2022 marks the 30th anniversary of the Agreement on the Conservation of Small Cetaceans of the Baltic, North East Atlantic, Irish and North Seas (ASCOBANS) – a regional environmental treaty of the United Nations. Concerns over the impacts of human activities on small cetaceans led to the negotiation of ASCOBANS under the auspices of the Convention on the Conservation of Migratory Species of Wild Animals (CMS). The Agreement was concluded on 17 March 1992 and has subsequently been signed by 10 countries.
