The term "co-major" indicates that students must complete another, primary major in one of the divisions at Miami University. There is no specific degree designation for the co-major; students receive the degree designation of their primary major. Completion of the co-major satisfies the Miami Plan thematic sequence requirement.

The Institute for the Environment and Sustainability offers 3 co-majors:

Energy Co-major

The goal of an Energy Co-major is to provide students with core interdisciplinary training in energy that complements their disciplinary majors in engineering, natural sciences, architecture, business, and the social sciences.
