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.

Description of the video:

The Master of Environmental Sustainability at the O'Neill School was created to meet the rising demand for sustainability experts in the green jobs market. It takes advantage of the full range of environmental science and policy faculty in the number one ranked environmental policy and management school in the nation.

One of the biggest benefits is that curriculum is focused not only on policy but also you can choose to follow the science path which is what I'm doing. I'm doing my concentration in environmental toxicology.

For me going back to grad school was important because I was changing careers midlife. I wanted to be competitive in the job market. It definitely means something to have a degree from IU and a degree from O'Neill.

You can do the MES either on campus or online and you can do it in a year or you can take as long as you need. You can also mix the types of classes to make your schedule and your lifestyle work best together.

I think it's unique because of the real-world application of the classes and the field-based classes. You get to go out, you get to get your hands dirty. Those opportunities combined I think takes it sort of beyond a textbook and I can really see the stuff that I learned in the class applied in my job.

Being on IU's campus has partnered me with a lot of great opportunities for my interests, like the Environmental Resilience Institute, Center for Rural Engagement. You get to build this real world experience while you're getting your degree.

O'Neill has a very good environment in terms of supporting and scaling up students through different services, like career services, which help you to prepare for the job interviews. As well as the faculty and the advisor are very supportive.

I knew I wanted to be with faculty who felt accessible, right? People who would be open to being mentors.

I like my academic advisor. She's a very renown scientist, but when you talk to her, she's also so funny and so approachable.

The Master of Environmental Sustainability students are going out across the spectrum. They're going into consulting jobs, agency jobs, nonprofit organization jobs. Some of them are going on to doctoral programs. Their specialty is that when they walk in the door, they have real world experience that makes them much more likely to be able to start doing things from the get-go.

I just appreciate everything this program has to offer. From the coursework to the professors. The people I've met by far are the best resource here. Everyone here has a common mission, serving the public for the greater good. And that's who I am. I want to leave a mark on this planet and I want it to be positive.
