Our Green History

In 2006 we held our first large school brainstorming sessions on sustainability, deciding at those meetings to make greening the school one of our major initiatives. It was clear to us that a 21st century education was not complete without teaching ecoliteracy and having our institutional behavior and campus model sustainable decision-making. Today our sustainability program is considered one of the best in the country and our graduates are known for their environmental activism and responsibility.

Our Philosophy

Princeton Day School’s mission is to prepare students “to act knowledgeably, to lead thoughtfully, to share generously, and to contribute meaningfully.”

To fulfill this mission we must graduate students who understand the ecological consequences of their actions, who have a sense of long-term decision-making and its effect on ecological health.

Princeton Day School believes that students are our largest carbon footprint, that their personal and professional decisions now and in the future will help determine the fate of the planet.

Our Goal

Our goal is to nurture a culture of environmental stewardship by working simultaneously in the areas of facilities, behavior, and curriculum. We want our graduates to understand that how they use resources affects the ability of future generations to also use those resources.

Isaac's Greenhouse and Penny Wallace '69 Courtyard Create Interdisciplinary Space

Princeton Day School formally dedicated Isaac's Greenhouse and the Penny Wallace '69 Courtyard in a ceremony on October 28. The new greenhouse was made possible thanks to a generous donation by Randy Mehrberg and his wife Michele Schara, parents of PDS alumni Sam '11 and Eric '19, and is named for the son of Sustainability Coordinator Liz Cutler. Ms. Cutler's passion to develop the School's sustainability program, combined with Isaac's radiant personality, inspired the Mehrberg-Schara family. See the full story and photo gallery.
