The global health care industry creates a large environmental footprint due to the supplies, water, and energy it requires, as well as the waste it produces. One recent report found that the health care industry is among the most carbon-intensive service sectors in the industrialized world, responsible for nearly 5 percent of worldwide greenhouse gas emissions. The same report found that the US health care system alone is responsible for about a quarter of all global health care greenhouse gas emissions. Given this outsized impact, the health care industry has great power — and responsibility — to build a more sustainable medical system. Thankfully, there are many ways at both the individual and system level to reduce carbon emissions and environmental impact without sacrificing quality.

The following resource guide to greening health care practice and advocating for more sustainable medicine was created in partnership between the Center for Innovation in Global Health and Dr. Barbara Erny, a Global Health Faculty Fellow and leader in health care sustainability.

Q&A: How to Green Your Practice

We speak with Dr. Paige Wolstencroft about how, as a resident, she and her fellow dermatology residents used quality improvement methods to reduce waste.

Resources for Greening Health Care

Recording: Greening Health Care

Stanford Medicine’s Resident Safety Council held a March 2022 workshop on climate health equity and greening health care. A few key takeaways included: Compost food supplies where possible; increase education about biohazardous and recyclable hospital materials; go paperless where possible; use reusable procedure supplies; turn off the water when you scrub in; advocate for custom procedure kits to include what you really use.

World Health Organization: Guidance for Climate Resilient and Environmentally Sustainable Health Care Facilities

The aim of this guidance is to enhance the capacity of health care facilities to protect and improve the health of their target communities in an unstable and changing climate; and to empower health care facilities to be environmentally sustainable, by optimizing the use of resources and minimizing the release of waste into the environment. View the guidance.

Guides for Environmentally Sustainable Practices in the Eye Health Sector

EyeSustain is a global coalition of eye societies and ophthalmologists collaborating to make ophthalmic care and surgery more sustainable. They have developed a robust website with resources to do so. Visit the website.

The Climate Action Working Group, with the International Agency for the Prevention of Blindness, has written a Guide for Environmentally Sustainable practices in the eye health sector, but many of its suggestions are broadly applicable to the health care sector.  View the guide.

Addressing Food Waste

Food waste is connected to climate change and food insecurity, two key drivers of global health challenges. Food systems account for over one-third of global greenhouse gas emissions, according to the United Nations. Hospitals can do more to reduce food waste and green their food systems. Following are a few articles and resources to reduce the environmental costs of food consumption.
