A plethora of environmental problems are ravaging the planet and its inhabitants. How well do existing structures convene governments to address these challenges? What is the role of science and civil society in this context? And, does international cooperation properly support countries with limited capacities? This report seeks to respond to these questions, based on an analysis of actions taken to renew international environmental governance to fulfill commitments made at the UN Conference on Sustainable Development (Rio+20) in 2012. This report outlines possibilities to strengthen the UN Environment Programme and to enhance synergies among global environmental conventions to ensure that international environmental governance continues evolving and improving to secure human well-being and planetary health.
