Environmental Sustainability
Environmental sustainability is an interdisciplinary field that integrates natural and social sciences, humanities, arts and education to address complex environmental problems. It attempts to balance human needs and ecological well-being, viewing humans as embedded within environmental systems.
As a student in the environmental sustainability program, you’ll learn how to understand the complex linkages between social and ecological systems and bring together knowledge from many different perspectives and disciplines. You’ll analyze environmental issues, collect data, connect the local and the global, apply various forms of theory, gain technical and applied skills and work collaboratively with others to find solutions to real-world environmental problems.

Recent graduates have been admitted to graduate programs in veterinary medicine, environmental policy and management, energy and earth resources, ecology, evolution and behavior, and museum education.
Understanding environmental systems through interdisciplinary research
This program prepares you through a collection of multi-disciplinary courses and a core environmental sustainability course sequence that helps you frame and link those diverse perspectives. In each core course, you’ll practice collaboratively addressing complex environmental problems, gaining increased autonomy and leadership throughout your four years.
Earlham is committed to sustainable living on campus and offers many opportunities for students to participate in environmental activities and initiatives. Learn more about our high sustainability ratings as a college and how we pursue sustainability at Earlham.
Choose a track
Environmental sustainability majors choose one of four tracks to focus their studies: environmental education, climate change, natural resource conservation or environmental culture and justice.
Off-campus study and research
From faculty research on sustainable cities in Europe to our popular semester program in New Zealand, environmental sustainability majors have a variety of options for studying around the world.

Our faculty
Because environmental sustainability is an interdisciplinary major, our faculty come from diverse departments, including politics, biology, geology, Japanese studies, outdoor education and English.
Program details
The environmental sustainability major will help you develop an understanding of systems and multi-perspective thinking through both local and global contexts. You’ll gain a critical understanding of environmental issues and gain technical and applied skills relevant to the field—including the use of the scientific method, GIS, statistics and more. Our alumni have gone on to work in conservation, city planning, community services, outdoor education and recreation and more.
As a liberal arts college, Earlham offers multiple disciplinary and interdisciplinary majors and minors in which students cultivate deep and specific knowledge and experience. Equally important, the College expects every student to develop broad, general skills and proficiencies across the curriculum.
As part of their general education, students complete six credits in each academic division of the College: humanities, natural sciences, social sciences, and visual and performing arts. In addition, students meet requirements for first-year courses, analytical reasoning, perspectives on diversity and wellness.
To earn a Bachelor of Arts in Environmental Sustainability, you’ll complete six courses within the major core and an additional 10 courses within the environmental education track.
