Elective Courses

BS-ES electives allow students to follow their curiosity, deepen their knowledge, develop new skills, and explore environmental questions across disciplines. They complement the program’s required courses and provide opportunities for students to pursue topics that align with their academic interests and evolving professional goals.

Electives and Your Custom Pathway

Beginning in their third year, students use electives as one of the primary ways to develop their Custom Pathway. Students select courses that build knowledge and skills related to the environmental questions they want to explore, while drawing connections across environmental science, governance, justice, and culture. Electives can be combined with quantitative and methodological coursework, internships, professional development, immersions, research, and other experiential opportunities to create an individualized trajectory through the program.

The courses below represent BS-ES electives that have been offered or are anticipated for upcoming semesters. Elective offerings vary by semester and continue to expand as new courses are developed by Earth Commons and faculty across Georgetown.

Recent & Upcoming Electives

Spring 2027 courses are anticipated and subject to change. Additional electives may be added as new courses are developed.  Keep in mind that electives can be drawn from ERTH courses as well as courses tagged with the attribute X-LIST: ENSU in the course catalogue.
