YCELP is a thought leader, source of policy analysis, dialogue convener, and catalyst for action towards a sustainable future. It provides teaching, research and outreach support on several environmental issues including global pollution control and natural resource management. YCELP works to positively influence and drive progress on issues such as regulatory reform, trade policy, the implementation of the 2015 Paris Climate Change Agreement, corporate sustainability and in measuring the environmental performance of countries around the globe through its Environmental Performance Index (EPI). The EPI, which has been YCELP’s flagship program since 1999, ranks 180 countries their environmental health and ecosystem vitality performance, provides insight on best practices, and offers guidance for countries that aspire to be leaders in sustainability. The Foundation has provided general support to this work since 2013.
