Environmental Science and Sustainability Major

You Will Gain…

  • An enhanced understanding—from scientific, social, and humanities perspectives—of the environment and current environmental issues.
  • Experience in solving actual environmental problems.
  • The ability to use modern research methods to explain observations about the natural world and about societies.
  • A network of alumni in government, industry, and the academic world linking students to jobs and graduate programs.

Because this program is interdivisional, students who major in Environmental Science and Sustainability may complete any minor to satisfy the college requirement that the major and minor be in different divisions. When appropriate, other courses – for example, new courses or those taken during study away – may be substituted for the section III requirement. All substitutions must be approved by the major advisor, and students are strongly encouraged to discuss any potential course substitutions prior to enrolling in the course.


The Environmental Science major requires 60 credits as follows:

I. Introductory Courses

Take the following two courses (8 credits):

ENVSC 110 - Introduction to Environmental Science
FSENV 201 - Environmental Problem Analysis

V. Systems Integration and Advanced Analysis Concentration:

Select seven additional courses (28 total credits) that are relevant to Environmental Science and Sustainability and that prepare students in a self-designed concentration. At least four of the seven courses must be advanced (300- or 400-level), and at least one of these courses must have an ENVSC course number. Courses must be selected in consultation with a faculty member in Environmental Science and Sustainability by the end of the sophomore year. For most students, this selection process will occur during enrollment in ENVSC 210. Students may change course selection during their tenure at Allegheny, however, the student's major advisor must approve all schedule changes.

VI. Learning Experience:

Students are strongly encouraged to complete at least one off-campus learning experience (e.g. EL seminar, semester away program, and research or internship experience) that relates to their Systems Integration and Advanced Analysis Concentration. Learning experiences may be credit bearing or non-credit bearing. Students should consult their major advisor when selecting and arranging learning experiences.

Graduation Requirements

The minimum GPA for a student to graduate with a major in Environmental Science and Sustainability is 2.0. All courses required for the Environmental Science and Sustainability major (including Allegheny off-campus courses for which a letter grade is posted on the Allegheny transcript) are counted in the calculation whether they are Environmental Science courses or courses listed outside the department. Courses required by the major are expected to be taken on a letter-grade basis. Exceptions must be approved by an Environmental Science department advisor.
