Master of Science in Environmental Science & Sustainability: Professional Track

There’s more to understanding today’s sustainability challenges than what you read in a blog or on Twitter. Build a toolkit of pragmatic workplace skills through coursework in some of today’s most prominent sustainability areas: sustainability assessment and planning, environmental law and policy, sustainable business practices, or several of our other areas of specialty.

Find the flexibility and diversity you need in a graduate program by selecting courses that are offered at the time and format that works best for you. Students in the Professional Track have the opportunity to take both classroom and online courses and can even complete this degree fully through evening and online course offerings.

Required Courses

ENVS 401 – Sustainable Systems: Ecological Perspectives

Learn how an integrated viewpoint on environmental science and sustainability connects the goals of ecosystem protection and sustainable development. Joining these objectives ensures fair and just solutions for both people and the planet. Determine best practices in evaluating data in environmental science and sustainability and making ethically informed decisions about them.

ENVS 402 - Sustainable Systems: Social Perspectives

The solutions to environmental problems require understanding social and economic approaches to sustainable development. Explore the social science, debates, and practical examples behind the application of environmental sustainability goals. Learn the tools used in evaluating and implementing development strategies that are sustainable.

Environmental Science Courses

Students will take at least two courses from more than 45 courses we offer in environmental sciences and quantitative methods. Select courses based on your particular interests; many also count toward the required concentration areas. LEARN MORE

Ping Jing

Assistant Professor, PhD, Earth and Atmospheric Sciences

“I am an atmospheric scientist. My major research questions are: How can we safeguard air quality for people in the Midwest in future climate? How will emissions change as the climate becomes warmer and we start to increase the share of sustainable energy sources? I hope the outcomes of my research will benefit the public and decision makers in their climate adaptation planning and air pollution control policy.”

Nancy Landrum

Professor, PhD, Business Administration

“Business and industry have both the responsibility and the resources to help us advance sustainability. I focus on what companies currently do and, more importantly, what they need to do to transition us toward a globally prosperous and sustainable future that improves quality of life while also creating an economic system that operates within planetary boundaries.”

Brian Ohsowski

Advanced Lecturer, PhD, Biology

“I think of ecological problems and solutions in terms of the big picture concepts. Habitat destruction and human influence does not stop at site-specific restoration projects. It is crucial to integrate sustainable technologies that reduce human waste and sequester greenhouse gases while creating native habitat.”


Do I need to have completed a particular type of undergraduate degree or taken particular coursework to be admitted into the IES Master’s program?

Applicants who have completed any type of undergraduate degree, regardless of specialty, will be considered for admission into the IES Master’s program. Students who are admitted to the MSESS Professional Track will work with their Graduate Faculty Advisor to determine if there are any courses they need to take before starting the program to prepare them for their particular research topic and study plan. Students admitted to the Professional Track will work with the Graduate Program Director to set a course of study. It is recommended that you select and choose courses and a program that are both challenging and of interest to you.
