Wellesley’s sustainability efforts are ongoing—check back here for the latest updates on this important work.


June 2019: A schedule for implementing energy conservation measures is established for summer 2019. Buildings to be upgraded include Alumnae Hall, Homestead-Instead, and Cheever House.

April 2019: Identified opportunity to revise agreement with Wellesley Municipal Light and Power (WMLP) that would ensure an additional seven to 10 percent of our electricity would come from renewable resources—bringing Wellesley’s total purchase of electricity from renewable resources to nearly one third. If approved, this purchase will reduce our carbon footprint by an additional 1000 metric tons, or approx. three percent.

March 20, 2019: A sub-group of the E2040 Committee began evaluating and interviewing technical consultants to aid in developing the plan to move the campus toward carbon neutrality by 2040. (A consultant is expected to be selected by the end of the 2018–19 academic year.)

Mid-March 2019: Facilities team and its contractors, Bond Brothers and Vanderweil, began putting together the final scope to undertake $6 million worth of energy conservation measures (ECMs) across campus buildings over the next three years. These measures will include lighting upgrades, HVAC system control upgrades, fan and pump efficiency improvements, and more.

January 30, 2019: First meeting of the E2040 Committee, which is comprised of trustees, faculty, staff, and students.

October 29, 2018: Based on recommendations from the Power4Women task force, the Board of Trustees has committed approximately $24 million to be spent from 2019 through 2021:

  • To spend $6 million to improve energy efficiency in our campus buildings.
  • To replace the College’s steam absorption chiller plant with an electric chiller plant.
  • To decommission our five natural gas electricity generators and partner with Wellesley Municipal Light and Power to provide the College with more renewable electricity.
  • To help lower our annual utility costs, we will construct a “peak-shaving” power plant that will generate electricity during peak electrical-use periods (approximately 600 hours each year) and during power grid failures.
  • To accelerate ongoing discussions with potential partners to increase production of energy from renewable sources, such as wind and solar power.
