The advanced writing component of the major in ENS requires registration in, and satisfactory completion of, the 0-credit MAR 459 or SUS 459 (S/U grading) along with enrollment in an approved advanced course that entails writing of either a term paper or a laboratory report. Completion of MAR 459 or SUS 459 with a grade of S will also result in fulfillment of the WRTD requirement.

Completion of the major requires approximately 62 credits. Of these, no more than one course (4 credits) with a grade lower than C can be credited to the major.

Excluding SUS 305 - Collective Action and Advocacy , no more than 6 credits of 300-400 level course credits can be applied between the Environmental Studies major and another major.
