The Office of Sustainability develops, coordinates and supports the aggressive sustainability initiatives at Princeton University. We work collaboratively with our students, faculty, staff, regional and national affairs offices, as well as with our local Princeton community to promote sustainability efforts and practices. With our networking and collaborative efforts, we are also part of a larger professional community promoting sustainability initiatives at other colleges and universities.

    Princeton University will undergo one of the most extensive building programs in its history over the next decade — adding some 3 million square feet in new construction to house more students, expand research facilities, and replace aging buildings and infrastructure. Construction on this scale could pose enormous sustainability challenges. Princeton, however, is embracing it as a once-in-a-generation opportunity to lay the foundation needed to achieve “net-zero” greenhouse gas emissions before mid-century.

    As part of Princeton University's goal to achieve climate neutrality by 2046, we are advancing our use of geo-exchange technology. Investing in geo-exchange projects, with enough capacity to serve the entire campus, will enable Princeton to phase out nonrenewable energy sources, including natural gas burned today to produce steam heat. Check out our new What is Geo-Exchange? flyer to understand how geo-exchange works, how we are not installing geothermal wells, and how our infrastructure projects work together to advance geo-exchange technology across campus.
