At Westtown, sustainability isn't a fad or something to check off a list; it's central to how we educate and live. You can see innovative, sustainable design everywhere on campus from the solar panels on the athletic center, to the LEED Gold Certified Science Center, to our organic student farm. We are so serious about sustainability, in fact, that we have been named a Green Ribbon School by the U.S. Department of Education. 

Students in all grades get into the act by engaging with natural systems and learning about the complex patterns they model. For example:

  • Lower Schoolers plant and maintain a National Wildlife Certified Native Plant Garden to attract birds and insects

  • Fourth grade produced a musical on sustainability themes to promote better recycling and conservation in Lower School

  • 7th grade science built a straw bale compost bin to handle school food waste and learn about decomposers' key role in the food chain

  • Upper School students can take advanced courses in Environmental Science and Research Ecology; classes as diverse as Calculus, Business and Ethics, Peace and Justice, World Religions and Economics address environmental issues.

  • Every Westtown student plants and harvests organic vegetables from the school’s beautiful 1 acre organic student farm

  • Earth Day gets the whole student body involved

  • Check out the Science Center's real time energy and water use here

Sustainability Mission Statement

We, the Westtown School community, will fulfill our mission to “inspire and prepare our graduates to be stewards and leaders of a better world” by committing to protecting and enhancing the environment through our teaching and our institutional practices. Guided by the principles of the Religious Society of Friends, we are called to lead by example in creating a community that sustains ecological systems and that makes environmental awareness and responsible environmental action core values.

The school’s decisions and actions will be guided by their environmental and educational impact now and in the future so that in meeting the needs of today’s Westonians we will support the mission, longevity, and future prosperity of the institution and the larger world. We will pay particular attention in our operations to sustainable land use and management, construction and renovation of facilities, and energy and resource consumption, giving priority to practices that can teach sustainability. 

Ultimately, our goal is to create an environmentally literate and responsible community of students, faculty, staff, and families whose daily actions reflect care for the earth and its biodiversity

Community Health and Sustainable Dining

Sustainable Dining

From student farm to plate sometimes takes only a few hours at Westtown; students might pick tomatoes as part of their morning work job, then enjoy them for lunch the same day.

The Dining Hall serves produce from the student farm year round, as well as produce from 80 area farms, delivered weekly from Philadelphia’s Common Market.

Westtown helped found the PA Association of Independent Schools Farm-to-School Buying Consortium which has encouraged over 20 area independent schools to source their produce locally.

Campus-wide No Tobacco and No Vehicle Idling Policies, plus use of low or no VOC paints and finishings in buildings where possible improve indoor air quality.

Energy Use

Alternative Energy

Westtown buys 100 percent of our campus electricity from renewable sources and models renewable energy generation on campus through

  • a 44 kW solar array on the Athletic Center.
  • geothermal heating and cooling in two dormitories, the science building, and five faculty homes
  • solar hot water in the LEED Gold science building, which opened in 2014.


Westonians take conservation seriously: Since 2007 we have

  • Cut campus electricity use by 18%
  • Reduced carbon emissions from heating, cooling, and electricity by 60%
  • Invested more than $500,000 from energy savings back into our programs
  • Begun setting a timeline for achieving carbon neutrality

Green Buildings

The Board of Trustees adopted a green building policy to ensure that new buildings and renovations meet strict energy and conservation guidelines.

  • The LEED Gold  Science Building  which opened in January, 2014
  • Balderston Commons and dormitory is geothermally heated and cooled, and is Energy Star Certified
  • The renovated Facilities Building received LEED Commercial Interiors Certification
  • Stone House dormitory is Geothermally heated and cooled
  • All faculty houses and campus buildings have received energy audits and retrofits

Recycling and Composting


  • With Single Stream Recycling campus-wide, we divert a whopping 55% of our waste from landfills -- up from 20% only three years ago.
  • Compost from all three divisions gets turned into fertility for the campus gardens, or feeds the chickens at our commercial farm.
  • Goal by 2015: 65% waste diversion

Land Management


Westtown’s 600-acre campus provides outstanding opportunities for learning: a 14-acre lake, a 200-acre commercial farm, a 1-acre student farm, old growth forest, and previously logged woodlands.

  • Students in all divisions get outside to observe, learn, and interact with the distinct ecosystems on the school’s 600-acre campus
  • The lake, used for student canoeing, skating, and fishing, will undergo dam replacement and restoration in spring and summer, 2015
  • Students participate in creating native plant gardens and growing food on campus
  • Students get into the act to help remove invasive plants in campus woodlands
