Yet the irony is that health care organizations, and the hospitals they operate, are no small players in contributing to climate change. Hospitals account for 8 percent of greenhouse gas emissions in the U.S. They spend $5.3 billion on energy every year, and use twice as much energy per square foot as traditional office space. They generate more than 2 million tons of waste per year. And they are among the top 10 water users in their communities, with some facilities using up to 700,000 gallons of water per hospital bed per year.

It’s a considerable environmental footprint. And as the consequences of climate change are becoming all the more real, posing the “biggest global health threat in the 21st century,” it is only natural that health care organizations should take a leading role in addressing this challenge.

And they are.

A growing number of health care business and clinical leaders are turning away from ideological disputes and tired political battles over climate change and are simply stepping up to the challenge. They are embracing environmental stewardship as part of their commitment to improving health. They are mounting a response to the health impacts of climate change that are predicted and are already being felt. And they are looking hard at the environmental impact of their hospitals and operations in order to address their role in driving climate change and do something about it.

Last month’s United Nations Climate Summit illustrates the complexity of getting world leaders to agree on a plan of action to tackle the climate crisis. By contrast, some of the world’s leading health care organizations see their mission of healing people and healing the planet as one and the same. They carry out their health care mission with the understanding that environmental health, community health and individual health often interact in such complex ways as to be often indistinguishable. If we want to achieve health, we must tackle all the determinants of health, and we must do it in partnership with one another.

In my book “Greening Health Care, How Hospitals Can Heal the Planet”, I examine the intersection of health care and environmental health, exploring the challenges that health care has faced in owning up to its impact on the environment. I look at the many ways that health care is helping to shift the dialogue around environmental sustainability by stepping up to the challenge of climate change in ways that, frankly, many world political leaders could learn from.

What are health care leaders doing?

Health systems including Dignity Health are committing to reduce their systemwide energy consumption through energy efficient upgrades and installation of renewable energy sources like photovoltaic, solar hot water, cogeneration and fuel cell technology across 35 percent of their enterprise.

Cleveland Clinic achieved impressive energy efficiency results simply by substituting more than 60,000 LED bulbs for nearly all the incandescent lights across their campuses and dimming nighttime lighting in hospital corridors. The result was a huge reduction in energy, with a savings of $4 million in energy costs per year.
