New Report Finds Global Health Care Sector Major Contributor to Climate Crisis

If the global health care sector were a country, it would be the fifth-largest greenhouse gas emitter on the planet, according to Health care’s climate footprint: How the health sector contributes to the global climate crisis and opportunities for action, a new report by Health Care Without Harm in collaboration with Arup.
New Report Finds Global Health Care Sector Major Contributor to Climate Crisis

Establishing the first-ever estimate of health care’s global climate footprint, the report finds health care’s footprint is equivalent to 4.4 percent of global net emissions. Fossil fuel combustion makes up well over half of health care’s global climate footprint. Overall, health care emissions are equivalent to the annual greenhouse gases produced by 514 coal-fired power plants.

The report, released simultaneously at events in London and Medellin, Colombia, makes the case for a transformation of the health care sector that aligns it with the Paris Agreement goal of limiting climate change to 1.5 degrees celsius.

“Not only are doctors, nurses and health facilities all first responders to the impacts of climate change, but hospitals and health care systems paradoxically make a major contribution to the climate crisis,” said Josh Karliner, international director of program and strategy for Health Care Without Harm and one of the authors of the report.

Hospitals, health systems and their supply chains in the United States, China, and collectively the countries of the European Union, comprise more than half of health care’s worldwide emissions. And while vastly differing in scale, every nation’s health sector directly and indirectly releases greenhouse gases as it delivers care.

The report calls for a global roadmap for climate-smart health care in order to reduce emissions, while meeting goals such as universal health coverage. The report also outlines immediate actions that stakeholders from across the health sector can take, including:

  • Individual hospitals and independent health systems should follow the example of thousands of hospitals already moving toward climate-smart health care via Health Care Without Harm’s Health Care Climate Challenge and other initiatives.
  • National and subnational governments should build on existing initiatives to establish action plans to decarbonize their health systems, foster resilience, and improve health outcomes.
  • Bilateral aid agencies, multilateral development banks, other health funding agencies and philanthropies should integrate climate-smart principles and strategies into their health aid, lending, and policy guidance for developing countries.

The report concludes that health promotion, disease prevention, universal health coverage, and the global climate goal of net zero emissions must become intertwined.

“The health sector must become climate-smart,” says Gary Cohen, founder of Health Care Without Harm. “Both climate justice and health equity depend on it.”
