Sustainability at Princeton

Major Initiatives on Campus

Sustainable Campus

Stewarding a Sustainable Campus. Princeton University has entered an unprecedented period of construction, with all projects incorporating multiple sustainable technologies.

Campus as Lab

Using Campus as a Living Lab. We work actively with student and faculty researchers in using Princeton’s campus for sustainability research and experiential learning.

Action Plan

Achieving Net-Zero. We recognized an opportunity to affect positive and significant change by converting from steam to hot water with geo-exchange technology and thermal distribution.

EcoReps

Engaging Campus. The Princeton University Ecology Representative Program (EcoReps) helps integrate sustainability into life on campus and into the daily lives of Princeton students.
