Overview

This episode explores Mass General Brigham’s (MGB) deep and evolving commitment to sustainability in healthcare. Through conversation with Dr. Winnie Armand and Dr. Greg Furey, leaders in hospital sustainability programs at Mass General and Brigham and Women's, the discussion dives into the motivations, major investments, clinical impacts, employee engagement, and practical advice for other health systems at various stages in their sustainability journey.

Key Discussion Points & Insights

1. The Imperative of Climate Action in Healthcare

• Healthcare’s Footprint: The sector accounts for ~9% of U.S. greenhouse gas emissions, making its decarbonization a public health necessity ([00:28]-[01:13]).
• MGB’s Mission: “Climate change is a public health crisis… contributing to a crisis that’s taking a devastating toll on human health is at direct odds with our fundamental mission.” — Dr. Furey ([01:13])
• Strategic Evolution: MGB has led on sustainability for over 25 years, starting with energy-focused efforts and evolving to encompass broader clinical, research, and educational initiatives.

2. Major Investments and Projects

• Energy Conservation: Implemented through Strategic Energy Master Plans I & II, with consistent upgrades and recalibrations over decades ([01:13]-[03:50]).
• Onsite and Offsite Renewables:
  • Rooftop solar in many facilities.
  • Participation in a consortium with Harvard, MIT, Apex Clean Energy, and others, investing in two large-scale renewable projects, together powering the equivalent of 130,000 homes over 15 years ([02:48]).
• Building Resilience:
  • Spalding Rehabilitation in Boston was designed with future flooding in mind.
  • Nearly “net zero” construction underway at Mass General, intended as a model for others ([03:50]-[05:13]).

Quote:

“This is probably the most environmentally sustainable building that MGB has ever embarked upon and I think serves as a model for many health care institutions…”
— Dr. Furey, [05:09]

3. Expanding Beyond Energy: Clinical, Research, and Educational Work

• Anesthesia Emissions: Projects to reduce GHGs from anesthesia (including nitrous oxide and metered dose inhalers).
• Reusable Devices: Single-use device reprocessing, buying back sterilized, FDA-cleared devices at reduced cost ([05:30]).
• Greener Laboratories: Initiatives targeting research lab emissions.
• Education & Engagement: Encouraging understanding of the climate-healthcare nexus among employees and trainees.

4. Employee and Clinician Engagement

• Strong Staff Support: Echoes national trends; “over 95% of our clinicians” completed an optional sustainability training ([07:24]).
• Training Relevance: Clinicians felt education was “very relevant to both their personal lives but also their clinical practice” ([08:15]).
• Notable Initiative: Sustainability education became a bi-annual quality incentive at Mass General Hospital.
• Publication & Outreach: Training results published in JAMA Network Open (2024), plus launch of a half-day virtual course, Pathways to Net Zero (November 5) ([09:10]).

Quote:

“We had a lot of feedback from physicians that took the training that they were very grateful for this education and… the steps that Mass General Brigham was taking.”
— Dr. Armand, [08:45]

• Community Health Focus:
  • AI tools to identify patients vulnerable to extreme heat (with IBM collaboration).
  • Community Health Needs Assessment now includes questions on climate impact and pollution ([09:50]).

5. Measuring Impact: Quantifiable Results and Clinical Changes

• Energy Savings:

  • 80% of MGB’s electricity now from renewable resources.
  • 122 energy conservation projects over four years yielded “about 39 million pounds of CO2” avoided annually (equivalent to 15,000 cars off the road) ([12:51]).
  • $4.3 million in annual energy cost savings ([13:40]).

• Clinical Practice Changes:

  • Anesthesia: Decommissioned leaky central nitrous oxide systems—“huge savings” in emissions.
  • Telehealth Expansion: Pandemic-driven increases in virtual care led to less emissions by reducing travel ([15:00]).

• Supply Chain Sustainability:

  • Growing use of reprocessed single-use devices.
  • Partnerships with suppliers for products with lower environmental impact ([14:50]).

Quote:

“At this point in time, Mass General Brigham gets about 80% of its electricity from renewable resources… That’s had a really dramatic impact on reducing emissions from our electricity consumption.”
— Dr. Furey, [12:53]

6. Day-to-Day Staff Involvement: “Sustainability on the Ground”

• Clinician-Led Initiatives:
  • Watching Our Waste: Surgery resident-led project to reduce red bag waste contamination—a type of regulated medical waste with high emissions and costs ([16:33]).
• Support Staff Collaboration: Environmental services worked with perioperative teams to upcycle blue wrap used for sterilizing instruments, keeping waste out of landfills.
• Food Services: Plant-based meals, antibiotic-free chicken, diverting food waste to energy via compost and anaerobic digestion; serving >30,000 meals/day ([18:05]).
• Glove Use Campaign: Occupational health team educates staff on reducing unnecessary glove usage, with 184 million gloves used annually systemwide ([19:11]).

Quote:

“I feel like this is a wonderful segue… Many of our staff want to be involved in sustainability efforts on a day-to-day level.”
— Dr. Armand, [16:33]

7. Advice for Other Health Systems

• Mission Alignment: Reframing sustainability as integral—not additional—to the healthcare mission and operational resilience ([20:42]).
• Return on Investment: “Many of the initiatives actually offer return on investment… There are multiple benefits with many of these initiatives.” — Dr. Armand ([21:20])
• Start Small: Seek low-cost, “easy wins” that are staff-led; sharing success stories fuels culture change ([21:38]).
• Resiliency & Quality: Sustainability often supports goals like reducing low-value care, improving system resilience (e.g., reusing isolation gowns during the PPE crisis) ([22:35]-[23:53]).
• Workforce Morale: Sustainability initiatives support staff retention by aligning with their personal values and combating burnout ([24:38]).

Quote:

“It shouldn’t be thought of as a burden or cost, but really something that is an imperative and is aligned with our mission.”
— Dr. Armand, [21:01]
“Our investments in energy conservation and renewable energy have resulted in substantial cost savings… sustainability initiatives are aligned with our other priorities.”
— Dr. Furey, [22:00]
