    U.S. higher education endowment to pledge net-zero greenhouse gas emissions from investments



In April 2020, we pledged to set our endowment on a path to achieve net-zero greenhouse gas emissions from investments in its portfolio by 2050.

This pledge was a first among U.S. higher education endowments and a natural extension of Harvard’s ongoing efforts—through its teaching, research, and operations—to accelerate the necessary transition to a fossil fuel-free economy. Read the report on early progress and engagement activities.

Harvard has 143 LEED certified buildings, more than any other higher ed institution.

  • 30%

    reduction in greenhouse gas emissions

In addition, Harvard has outlined an ambitious goal to be fossil-fuel neutral by 2026 and fossil-fuel free by 2050. We’re also continuing to maintain the 30% reduction in greenhouse gas emissions that we’ve already achieved.

We have 2.513 MW of on-site solar through our 27 different installations, enough to power over 500 homes.

  • Compost

The University’s compost is sent to an innovative facility at Save that Stuff to be processed into a high-energy product that is eventually shipped to a local wastewater treatment plant to produce energy.
