As a major provider of healthcare services to the people of Maine and a leader in the health and wellness field, we are taking steps to minimize our environmental impact while providing excellent care in a sustainable manner.

We have signed the U.S. Department of Health and Human Services Health Sector Climate Pledge to reduce emissions 50% by 2030 and achieve net zero emissions by 2050. We are making a long-term commitment to organizational sustainability and reducing our contribution to climate change.

Here we will highlight some of the activities currently underway, and share future ideas and goals designed to minimize our environmental footprint. We can proudly say that thousands of employees throughout our system are engaged and supporting this important work.

Our Commitment to Sustainability


  • We are increasing employee awareness and engagement through internal communications platforms and quarterly newsletters.
  • We regularly include educational speaker for our internal workgroup meetings.


  • Northern Light Health developed a Climate Resiliency Plan to identify risks and vulnerabilities related to extreme weather events, rising temperatures and sea level, air quality, water access, diseases transmitted by insects, as well as how climate affects the health and well-being of our patients.
  • We have committed to source 60% of our electricity from renewable sources. This procurement strategy is a priority that we will continue to expand upon.
  • Historically, the Northern Light Health vehicle fleet has been gasoline and/or diesel powered, but through replacement and end-of-service life opportunities, we are incorporating hybrid or fully electric options whenever possible.
  • Supply Chain contracting processes now include vendor sustainability criteria.
  • Hospital boilers are being converted from #2 fuel to propane when appropriate, resulting in substantial greenhouse gas reduction and a cost savings benefit.
  • Many efforts are underway to reduce our electrical consumption across the system.


  • Northern Light Health was a member of the Climate Can’t Wait workgroup of the Institute for Healthcare Improvement (IHI) and is now part of IHI’s Decarbonizing Care Learning Community.
  • Northern Light Health is partnering with The University of Maine’s Senator George J. Mitchell Center for Sustainability Solutions to complete hospital food waste audits, the results of which will inform food service programs’ waste mitigation efforts across the organization.
