Global Biodiversity Outlook 4

Global Biodiversity Outlook (GBO) is the flagship publication of the Convention on Biological Diversity. It is a periodic report that summarizes the latest data on the status and trends of biodiversity and draws conclusions relevant to the further implementation of the Convention.

The fourth edition of the Global Biodiversity Outlook will be officially launched on the opening day of the Twelfth Meeting of the Conference of the Parties to the Convention on Biological Diversity (COP 12) in Pyeongchang, Korea. The report draws on various sources of information to provide a mid-term assessment of progress towards the implementation of the Strategic Plan for Biodiversity, an issue which will be discussed during COP-12.
