Scott Barrett is Professor of Environmental Economics and International Relations of Political Economy, Director of the International Policy program, and Director of the Global Health and Foreign Policy Initiative at the School of Advanced International Studies (SAIS).
His research focuses on interactions between natural and social systems, especially at the global level. Natural systems (such as the climate or the ecology of a pathogen) tend to be united. By contrast, the international system, comprising some 200 states, is highly fragmented. Barrett concentrates on the institutions that mediate between these two worlds. Examples include the Kyoto Protocol, intended to halt global climate change, and resolutions passed by the World Health Assembly, including those aimed at eradicating polio.
He is probably best known for his work on international environmental agreements, for which he received the Erik Kempe Prize. His book on this subject, Environment and Statecraft: The Strategy of Environmental Treaty-Making, was published by Oxford University Press in 2003. It was published in paperback with a new afterword in 2005.
He has been writing on global climate change policy since the late-1980s, and is still involved in this area. He contributes to a blog at : http://www.climatepolicy.org
