The University of Michigan offers the only engineering and environmental science dual Master's degree. The Engineering Sustainable Systems (ESS) program brings together two nationally recognized programs at U-M to train graduate students who will create engineered systems that are socially, environmentally, and economically sustainable. A total of 54-credit hours must be completed to earn both an M.S. in Natural Resources and Environment and an M.S.E. in Mechanical, Chemical or Civil & Environmental Engineering. The Ford Motor Company Fund has provided support for curriculum development and for fellowships for graduate students in the ESS program.
