Our Masters and undergrad BA and BS programs train students to become effective advocates for the environment. The curriculum consists of rigorous science- and policy-based courses and experiential learning that prepare our students for exciting careers in the environmental field. The Department of Environmental Science recommits itself to advancing informed, knowledge-based approaches to confronting local and global environmental concerns.
See some of the ways AU and CAS students and faculty pursue sustainability.
Professor Stephen Macavoy co-authors Climate Change, Science, and the Politics of Shared Sacrifice with qualitative, quantitative, and hands-on methods for empowering students to investigate and take action.

Sergio Morales (Environmental Science) and Jennah McDonald (Biology), were part of the SEA Semester voyage that discovered good news regarding coral health in the Phoenix Islands Protected Area (PIPA). Their discovery was featured in the New York Times. Accompanied by 21 other undergraduates, SEA Semester faculty, and researchers from the New England Aquarium and the Woods Hole Oceanographic Institution, Sergio and Jennah gathered data on the health of the islands' coral reef ecosystem in order to recommend policy implementations to the PIPA management office in Kiribati—all while sailing as active crewmembers aboard a tall ship research vessel.

Hana Bahlawan BS Environmental Science '22
Hana Bahlawan is a senior majoring in Environmental Science. She is also a member of the US Air Force ROTC (Lt. Col. AFROTC)! Hana is examining the concentration and distribution of a novel PAH (polycyclic aromatic hydrocarbon) called Bibenzyl which is used in flame retardants, electronics, and textile production. She is looking at both suburban and urban steam sediments that may receive different degrees of sewage input and will test for differences.
Faith Lewis BA Environmental Studies and Economics ‘20
As a Student Sustainability Educator, I like finding out what people are interested in, and then catering to those interests. The environment affects everybody, and it's really our job to show people the way in which it affects them. It helps that people are very receptive at AU, so I don't have a hard time engaging with people.
I hope people see the merit of what we’re doing & are inspired to join the fight
Find out how you can get involved with Sustainability at AU.
