Deerfield Academy has adopted a forward-looking sustainability mission statement (below) and has created a Sustainability Action Plan to help us bring our community together on this important issue.

Deerfield Academy Sustainability Mission Statement
Deerfield Academy seeks to preserve our heritage by operating in a manner that sustains our natural and human resources for future generations. Through an intentional program both in and outside of the classroom, Deerfield Academy will educate all its members on local and global impacts of personal and institutional choices, encouraging long-term thinking and modeling environmental best practices.

Deerfield Academy has supported the economic and ecological health of the Pioneer Valley for over two centuries while creating a world-class educational community. We have been good stewards of our land, our community, and our history, while training generations of students to become local, national, and international leaders. Over time, however, changes in both technology and human population have created the necessity to adjust both the way we think and the way we operate. There are choices to be made. From the food we serve, to the care of our athletic fields, to how we heat our buildings in the winter, our decisions matter. Some choices will sustain our communities, while other options could degrade ecological, societal, and physical health, both at Deerfield and around the globe. In order for our graduates to be equipped to evaluate such options we must model exemplary environmental stewardship and educate our students to do the same. In light of these considerations, Deerfield Academy makes the following commitment to sustainability.

The Deerfield Academy Commitment to Sustainability

Deerfield Academy will use resources responsibly by:

    • Reducing our overall consumption of resources.
    • Minimizing our use of non-renewable resources.
    • Expanding our reuse and recycling of materials.
    • Using renewable resources sustainably.

Deerfield Academy will preserve the health of our community by:

  • Operating in a manner that preserves and enhances the physical and ecological health of our local and global communities.
  • Helping to support the health of the local economy through local purchasing, contracting, and partnerships, fostering greater sustainability in the local community.
  • Operating in a way to minimize our contributions to harmful climate change and other global environmental challenges.

Deerfield Academy will teach and model environmental best practices and long-term thinking by:

  • Incorporating themes of sustainability across the curriculum, through courses that focus on environmental issues as well as through courses that use environmental examples to explain more disparate concepts.
  • Teaching sustainability through experiential and place-based methods, strengthening our connections to River, Rock, and Valley.
  • Demonstrating best environmental practices as an educational tool for students and the community.
  • Using life-cycle analyses and long-term thinking when evaluating alternative plans for new construction, renovations, purchasing, energy generation, and operations.

Frequently Asked Questions

For the past several years, Deerfield has participated in the Green Cup Challenge, an interscholastic energy conservation competition. The school that reduces its kWh usage by the largest percentage wins. The school that reduces GHG emissions by the largest percentage is recognized.

Deerfield runs an on-campus competition during the Green Cup Challenge. Through the month-long challenge, our students follow the success of their dormitory on our energy dashboard and compare their achievements to their on-campus peers and to other schools. The dorm that reduces its energy the most from an established baseline wins a significant prize—an on-campus activity for themselves and another dorm of their choosing, AND a cash prize proportional to dorm size. Because the Green Cup Challenge is a month-long event, we believe that the changed energy consumption practices are more likely to become a learned behavior.

Think 80|20 is Deerfield’s campus recycling program, which has the goal of changing our habits so that only 20% of our campus waste ends up in a landfill. Think 80|20 signs are posted in all campus buildings and on all recycling/compost/landfill receptacles to educate people on how to dispose of their waste appropriately.

The Energy Dashboard displays daily, weekly, and annual energy consumption information in a building-by-building format. In addition, you can track the performance of solar power systems on two buildings. The Dashboard is an integral part of coursework in many classrooms, and it is wildly popular during the Green Cup Challenge each year.

Environmental proctors are student leaders in sustainability efforts at Deerfield Academy. Working with the Sustainability Coordinator, e-proctors participate in a variety of projects, including dormitory recycling and energy conservation challenges, and promote sustainability around campus.

E-proctors are required to attend biweekly meetings, be involved in one “project” per term, post sustainability announcements and educational materials in dorms, and be a role model for their peers. They will play an important part in helping Deerfield to be environmentally sustainable. A complete list of e-proctors’ duties is available online.

Upperclassmen can apply to become e-proctors each fall.
