The 4th Global Biodiversity Outlook (GBO 4) was officially launched on 6 Oct 2014, during the opening day of the Twelfth Meeting of the Conference of the Parties to the Convention on Biological Diversity (COP 12) in Pyeongchang, Korea. 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.

GBO 4 is a comprehensive report that serves as a mid-term analysis towards the 20 "Aichi Biodiversity Targets". The report states significant progress towards meeting some components of the majority of the Aichi  Biodiversity Targets. Some target components, such as conserving at least 17 per cent of terrestrial and  inland water areas, are on track to be met. However, in most cases this progress is seen as not sufficient to achieve the targets set for 2020, and additional action is required to keep the Strategic Plan for Biodiversity 2011–2020 on course.
