He held a number of leadership roles at the U.S. Environmental Protection Agency from 1989-93 including service on the U.S. delegation that negotiated the 1992 Framework Convention on Climate Change. From 2011-14, Esty served as Commissioner of Connecticut’s Department of Energy and Environmental Protection. He recently concluded two years of public leave from Yale — during which time he worked at the World Trade Organization helping WTO Director General Ngozi Okonjo-Iweala develop a sustainability strategy for the global trading system. He co-leads the Remaking Trade for a Sustainable Future Project and, with a network of thought leaders around the world, developed the Villars Framework for a Sustainable Trade System.
