As an initiative to assess the global environment, the United Nations Environment Programme (UNEP) produces the Global Environment Outlook (GEO) to assess the current state of the environment and the challenges that the environment and its inhabitants face.
The most recent publication is the sixth Global Environment Outlook 2019 – GEO 6; which calls upon the decision-makers, policy-makers and all of society to work on addressing the current environmental issues and pave the way in achieving the United Nation’s Sustainable Development Goals (SDGs) and other international environment goals (e.g. the Paris Agreement). Through these assessments, they use scientific information and data while analysing available environmental policy to identify the issues that need to be addressed in achieving sustainable development by 2050.
