Nate Hultman is the Founder and Director of the University of Maryland Center for Global Sustainability, and Professor in the School of Public Policy. He is currently on leave, serving as a Senior Advisor in the Office of the Special Presidential Envoy for Climate at the U.S. Department of State. 

Hultman’s research focuses on assessing and developing national climate strategies, combining quantitative assessment and modeling with policy development and engagement. This includes U.S. emissions mitigation policy including the role of non-federal actors, rapid and structured coal phaseout strategies in diverse national contexts, as well as economy-wide strategies in other major economies, with a focus on China as well as Brazil, India, Indonesia, and others. He was lead author of several recent assessments of U.S. national emissions mitigation strategies in advance of the announcement of the U.S. 2030 climate target (NDC). From 2014-2016, Hultman worked at the White House on the Obama Administration’s climate and energy policy team. During this time, he helped develop the U.S. 2025 NDC, worked on bilateral engagements with China, India, Brazil and others, and participated in the international climate negotiations in Lima and Paris. He has participated in the UN climate process for nearly 25 years. 

When not on leave, Hultman is also a nonresident senior fellow at the Brookings Institution, and associate director of the Joint Global Change Research Institute, a collaboration between the University of Maryland and the Pacific Northwest National Laboratory. He was formerly a visiting fellow at the University of Oxford, a Fulbright fellow, and a NASA Earth Systems Science fellow. He holds an M.S. and Ph.D. in energy & resources from the University of California, Berkeley, and a B.A. in physics from Carleton College

Designed for students whose academic majors would be enhanced by the complementary study of a widely shared but hard-to-operationalize aspiration: that present choices should preserve or improve future options rather than foreclose or degrade them. How should we understand sustainability? How might we achieve it? How would we know if we had achieved it? And how could sustainability activists of a rising generation lead by example?
