In a groundbreaking move, healthcare systems across the United States are phasing out the use of the anesthetic drug desflurane due to its significant environmental impact as a potent greenhouse gas. Hospitals are instead transitioning to alternative anesthetics like sevoflurane that are far less harmful to the climate, while also adopting low-flow techniques to reduce waste. This shift is not only better for the planet, but also more cost-effective for healthcare providers.

Why it matters

Desflurane is a powerful greenhouse gas, and its widespread use in hospitals has contributed substantially to the medical sector's carbon footprint. By eliminating or reducing desflurane, healthcare providers can make a meaningful dent in their environmental impact, setting an example for other industries to follow. This transition also demonstrates how doing good for the planet can align with cost savings and improved patient care.

The details

In 2013, the Yale New Haven Health System became the first in the U.S. to ban the use of desflurane, opting instead for the less environmentally damaging sevoflurane. This decision has saved the health system $1.2 million annually on anesthesia medications. Other major healthcare providers, such as the University of California system, have since followed suit, with estimates that these changes have reduced greenhouse gas emissions from anesthesia by 90%. Hospitals are also adopting low-flow anesthesia techniques and minimizing the use of nitrous oxide, another potent greenhouse gas.

  • In 2013, the Yale New Haven Health System became the first U.S. hospital to ban desflurane.
  • Over the past decade, the use of desflurane in medical procedures has declined from approximately 50% to just 10%.

What they’re saying

“Imagine the impact if every hospital followed suit. With 6,000 hospitals across the nation, the potential for change is immense.”

— Dr. Sherman

“It's a no-brainer. If we can provide the same high-quality care while reducing our environmental impact, why wouldn't we?”

— Richard Dutton, Leading figure, US Anesthesia Partners

What’s next

As more healthcare systems adopt these environmentally-friendly anesthesia practices, the medical industry as a whole is expected to significantly reduce its carbon footprint in the coming years. Experts predict that this shift will serve as a model for other sectors to follow, demonstrating how strategic, sustainable choices can benefit both the planet and the bottom line.

The takeaway

This movement within the healthcare industry shows how small, targeted changes can have a major collective impact on the environment. By eliminating the use of a single, highly potent greenhouse gas in medical procedures, hospitals are leading the way in tackling climate change, proving that doing good for the planet can also be good for business.
