The PhD program in Environmental and Energy Policy provides opportunities for conducting interdisciplinary research in support of sustainable and equitable development. Students’ research contribute to environmental goals such as facilitating the transition to sustainable energy systems, effectively managing the world’s scarce water and other natural resources and protecting the ecosystem services upon which we all depend. The opportunities for research exist at many scales, from projects involving local watersheds and urban recycling programs, to global supply chains and international treaties. The PhD program prepares students to conduct independent research with essential training for government, corporate, college and university, or non-profit careers.
