Columbia Sustainable Development: a science-led major declared after arrival

Columbia admits students to Columbia College or to Columbia Engineering, and Sustainable Development is a major offered by the Earth Institute with Columbia College and other schools. The Bulletin says the major focuses heavily on the sciences, which separates it from a conventional economics or political-science route and from an engineering degree. This guide covers how the major is built, how it is entered and what Columbia says about testing, and it makes no claim of a separate admission to Sustainable Development.

What Columbia says about Columbia Sustainable Development

Taken from the Columbia Bulletin entry for Sustainable Development and Columbia Undergraduate Admissions' Academics, Testing and International Applicants pages, read on 1 November 2026. The pages carry no entry-year label, so for a 2028-entry application every statement below is evidence for the previous cycle and may change; check Columbia's pages for the 2028-entry details.

A major declared after arrival

Columbia College students typically declare their major in the spring of the sophomore year. The pages read describe no separate admission to Sustainable Development.

Run by the Earth Institute

The Bulletin says the Earth Institute offers the major and a special concentration in collaboration with Columbia College, General Studies, SIPA and three departments.

Heavily science-based

The Bulletin says the major focuses heavily on the sciences and gives a working knowledge of interacting subject areas.

At least 15 courses and a practicum

The Bulletin says the major requires a minimum of 15 courses and a practicum, with foundation courses taken first.

The SAT or ACT is required from August 2027

Columbia says it will require first-year students to submit ACT or SAT results; it accepts A levels and the IB.

Read on 1 November 2026 on the Columbia Bulletin entry for Sustainable Development and Columbia Undergraduate Admissions' Academics, Testing and International Applicants pages, which describes 2027 entry. The pages carry no entry-year label. Columbia's Earth Institute and Climate School websites, the full requirements list, the course descriptions, deadlines and financial aid were not read and are not stated.

The major

What the Bulletin says the major is

The Bulletin describes sustainable development as an emergent interdisciplinary field and says the programmes aim to give theory and practice, a critical look at historical antecedents and direct experience of complex challenges. The major focuses heavily on the sciences. Its foundation courses, Science for Sustainable Development and Challenges of Sustainable Development, are taken in the first year, and the major then needs a minimum of 15 courses and a practicum. The Bulletin also names a companion degree that lets students earn a bachelor's and a master's in five years. This guide does not describe the course lists.

Is it the right major?

Sustainable Development, Columbia Engineering or a conventional major

Columbia describes the schools separately, so the school choice is made at application and the major after arrival. Avandy's comparison is general.

Sustainable Development fits if

you want environmental and sustainability questions studied across sciences and policy, with an Earth Institute adviser.

Columbia Engineering fits if

you want to design and build technical systems. Admission to Columbia College or Engineering is a separate choice at application, covered in Avandy's Columbia College or Engineering guide.

A conventional economics or political-science major fits if

you want a single social-science discipline rather than a science-led interdisciplinary programme.

Admission and testing

Columbia College, an SAT or ACT and A levels or the IB

Columbia says students apply to either Columbia College or Columbia Engineering. It accepts all secondary school curricula, including the IB and Cambridge A Levels, and reviews applications within the context of the curriculum. It says that starting in August 2027 it will require first-year students to submit ACT or SAT results. Sustainable Development is not a separate application. This guide states no score.

A decision framework

Three questions before you commit

This is Avandy's own framework, not Columbia's.

Are you comfortable with a science-heavy interdisciplinary major?

The Bulletin says the major focuses heavily on the sciences.

Is Columbia College the right school for you?

The school choice, College or Engineering, is made at application.

Can you plan the SAT or ACT with your A levels or IB?

Columbia says it will require one of them from August 2027.

Planning for 2028 entry

Planning for 2028 entry: what carries over and what is awaiting publication

Columbia's pages carry no entry-year label, so nothing on them is confirmed for 2028 entry. Use them to understand the structure of the application, then check Columbia's own pages for the 2028-entry details.

The requirements and descriptions on the pages read on 1 November 2026, which carry no entry-year label

These are the best guide to what to prepare. Columbia has not confirmed them for 2028 entry.

Deadlines, fees, financial aid and any department prerequisites not quoted here: not stated

This guide has not read them. Check Columbia for the values that apply to your application year.

What to do now

Read the Sustainable Development entry in the Columbia Bulletin and plan the SAT or ACT alongside your A levels or IB.

Support

Independent support with planning your own application

Avandy provides independent academic and admissions support. It is not affiliated with Columbia College or any of its colleges or departments. Preparation sits within the Avandy Trinity Advisory Model: a Strategic Admissions Consultant, a PhD-level Academic Mentor and a Subject-specific Tutor, working to the actual requirements of each course. Support here is limited to understanding the requirements and planning the applicant's own work; Avandy does not write or edit essays, does not submit any materials and has no partnership with Columbia College. No outcome is promised.
