The development of the United Nations Environment Programme (UNEP)’s Medium-Term Strategy (MTS) for the period 2022-2025 has come to a critical juncture. UNEP’s next MTS is being developed against an unprecedented opportunity: to ensure that, as nations invest in building back a better world from the current COVID-19 pandemic, their efforts do not merely recover the unsustainable economic models of yesterday, but help us build a healthier, greener and more resilient economy that is centered on human and planetary wellbeing.
