The Global Biodiversity Outlook (GBO) is a periodic report that summarises the latest data on the status and trends of global biodiversity. It is the flagship publication of the Convention on Biological Diversity and summarises progress made towards achieving the objectives of the Convention, such as the Aichi Targets and identifies key actions to achieve these. The Outlook is prepared by the Secretariat of the Convention on Biological Diversity drawing on information from national biodiversity strategies and action plans, national reports submitted by the Parties to the Convention, scientific literature, scenarios, and biodiversity indicators. There have been four editions of the Global Biodiversity Outlook and the fifth edition will be launched in May 2020.
The second meeting of the Conference of the Parties to the Convention on Biological Diversity in 1995 called for a periodic report on biological diversity, including a summary of the status of biodiversity and the steps taken to achieve the objectives of the Convention. Subsequent meetings of the Conference of the Parties provided specific mandates for the preparations of the individual editions of the GBO.
The GBO reports, as well as the technical underlying studies, undergo peer review.
