The medium-term strategy (MTS) of the United Nations Environment Programme (UNEP) sets out an analysis of the significant environmental challenges that the world will face in the coming years. Within this framework, the MTS for the period 2018 - 2021 is informed by relevant resolutions and decisions of the United Nations Environment Assembly, the General Assembly and the UNEP Governing Council, and by the strategies and plans of multilateral environmental agreements and other internationally agreed environmental goals.
