Princeton University strives to integrate the principles of sustainability across all campus systems and to lead by accelerating implementation of sustainable solutions locally and globally. Spearheaded by the Office of Sustainability and campus partners, Princeton adopted a comprehensive Sustainability Plan in 2008. An updated plan is anticipated for launch in 2016.

The current Sustainability Plan identifies three priority areas — greenhouse gas emissions reduction; resource conservation; and research, education and leadership. As a key feature, Princeton has committed to reducing its absolute local greenhouse gas emissions to 1990 levels by 2020 without the purchase of market offsets, and while expanding the campus population and square footage.

In 2014, Princeton published its sixth sustainability progress report. This report highlights improved performance trends in a number of key areas including carbon dioxide emissions, local and sustainable food purchases, and waste reduction. Academically, progress includes increasing development of and enrollment in sustainability-related courses, increased national and international sustainability internship participation, increasing numbers of students graduating with environment and sustainability-related degrees and certificates, and a newly launched Campus as Lab Innovation Fund for academic research.
