Environmental Sciences Major
The major in Environmental Sciences has two tracks: one in science (Science Track) and one in economic policy (Policy Track). The tracks share foundation courses in science and math, and the core curriculum. Advanced coursework differs by track.
Students plan their academic paths with an environmental sciences adviser. Many foundation courses are prerequisites for advanced courses and should be completed as soon as possible. Students envisioning graduate training in Environmental Sciences are specifically encouraged to take additional math and the full sequence of either General Physics or 200 level Biological Sciences. Students interested in environmental health and medical professions are advised to take the full 200-level sequence in biological sciences and two additional quarters of organic chemistry.
Students must also complete the Undergraduate Registration Requirement and the degree requirements of their home school.
NOTE: This Catalog describes Weinberg College BA requirements that pertain to students who matriculated at Northwestern after spring quarter 2023. Refer to the Archives if you are following BA requirements described in the 2018-2019 through 2022-2023 editions.
Major Requirements: Program Courses (11 units)

Honors in Environmental Sciences
Students with strong academic records and an interest in pursuing honors should approach a faculty member by the end of junior year to discuss possible projects; these may involve field, experimental, or computational research. Research is completed during a minimum 2 quarters of ENVR_SCI 399-0 Independent Study with their faculty research mentor, which may count toward major requirements. Students then prepare a written thesis. Those whose theses and grades meet program criteria are recommended to the college by their faculty mentor for graduation with honors. For more information consult the program director and see Honors in the Major.
