The World Environment Situation Room (WESR) is a ‘Single-Entry Door to a UN Data and Knowledge Platform on Environment’. It supports data-driven analysis, decision making and policy development on environmental issues by UN actors, governments, academics, private sector, and the public actors. The goal of WESR is to enhance transparency and timely feedback on the effectiveness of environmental policies, laws and governance frameworks, including the SDGs and MEAs where UNEP acts as a custodian agency for data. The unique value proposition of WESR is that it is an impartial and open data platform backed by the legitimacy of the United Nations with datasets and analysis that are curated based on quality and relevance by UNEP experts and collaborators.
