Sustainability at Andover

As we educate the next generation of environmental decision-makers, the Phillips Academy Climate Action Plan presents a whole school approach to engage on climate change and sustainable development. Our overarching goal is to reduce energy use, greenhouse gas emissions, water use, and waste on campus in a financially sustainable way.

Climate Action Plan Principles

  • EDUCATION Educate and engage the entire community on climate change and incorporate sustainability throughout the Academy.
  • INFRASTRUCTURE Increase the sustainability of campus buildings and infrastructure; conserve energy, reduce water use, decrease and divert waste.
  • ENERGY Generate and use cleaner and renewable energy on campus.
