Master of Environmental Sustainability (MES)

Shaping tomorrow: Master solutions for integrated social, economic, and environmental sustainability

The Master of Environmental Sustainability (MES) is an accelerated one-year, 36 credit-hour degree program that will prepare you for a career leading the business of sustainability in the public, private, or nonprofit sector.

With an enhanced, cutting-edge core curriculum that focuses on social, economic, and environmental sustainability, as well as a newly added concentration on environmental policy and planning, you’ll master the quantitative, economic, and management skills required to meet the exploding demand for “green” jobs across the nation.

By starting the MES in early August, you can complete your degree in just one year. If you finish the program in the summer term (May-July), you will be eligible to participate in the May commencement ceremony and will have your degree conferred at the end of the summer term.

Upon completion of this degree, international students will be eligible for the STEM OPT extension.

You are not required to complete the program in one year — you may take the degree more slowly if that is better for your schedule. Or, if you need extended time to fit your lifestyle needs, consider our self-paced online program.
