When you think of the biggest polluters of greenhouse gas emissions, health care may not be top of mind. But the health care system is responsible for 8.5 percent of GHGs in the U.S. and about 5 percent globally.

This ranges from facilities being hit with extreme weather and volatile energy prices to patients experiencing heat-related ailments or new illnesses brought on by changing disease vectors from a warming climate. Health systems are also chronically underfunded, and the current administration’s reduction of health care funding will exacerbate the problem.
