It was the spring of 1930. After months of research and meetings with faculty, Principal Lewis Perry traveled to New York to meet with Edward S. Harkness, his close friend and one of the country’s leading philanthropists. With him, Perry brought an outline of how Exeter planned to use a substantial gift Harkness had proposed to make to Phillips Exeter.
Documents preserved in the Academy Archives make one thing dramatically clear: Harkness was not pleased by Perry’s proposal. “You are thinking of improving an existing institution by building on what you have got now. I am thinking of something much more radical than that,” Harkness told him. Funding small improvements—an expanded advising system, a guest speaker series—did not interest Harkness. He wanted to see a proposal containing ideas “of a fundamental nature that were so sweeping and so different from methods prevailing here that one could see at a glance that were they adopted, the whole educational system in our secondary schools would not only be changed, but changed enormously for the better.”

Harkness sent Perry and his committee back to the drawing board. Six months later they returned with a plan that Harkness agreed to fund. The gift Harkness made to Exeter—the munificent sum of $5.8 million, the equivalent of $69 million in today’s dollars—seemed to fall from the sky at a time of great need at the Academy. Harkness was not a graduate of Exeter and had no formal ties to the school. His unprecedented generosity revolutionized teaching at Exeter and continues to define an Exeter education in every way 75 years later. This much is commonly known to those associated with the Academy.
The document begins with a refreshed environmental mission statement and three overarching goals, then lays out a strategy to achieve them. “If Exeter is to create a truly sustainable campus and meet our responsibilities to future generations, we must set goals that match the urgency and scope of the climate crisis,” the document declares. The plan — endorsed in concept by the Trustees in January and made final this spring — leans on the good work done by the Exeter community over the last two decades and a campus culture of conservationism prevalent since Exonians commemorated the first Earth Day 53 years ago. It also recognizes that the immediacy and complexity of climate change has grown since the school’s adoption of an environmental mission statement in 2004. “Consequently,” the plan reads, “our commitment to reducing our environmental impact and educating our students [on the issue] has increased, and must continue to increase.”
The school has made significant progress in curbing greenhouse gas emissions, slashing output by nearly 60% since 2005. Eight buildings use geothermal wells for heating and cooling, and a solar array installed in 2018 atop William Boyce Thompson Field House has generated an annual average of 575,000 kilowatts of electricity, enough to power 54 homes.
Biggins says that if one were to build PEA from scratch today, achieving zero carbon would be in the blueprints. “You’d have your buildings heated and cooled via heat pump, and your water heated via heat pump,” he says.
