"The medical system is responsible for a surprisingly large percentage of greenhouse gas emissions, and the toll is especially heavy in the U.S. The health care industry “is among the most carbon-intensive service sectors in the industrialized world,” accounting for between 4.4% and 4.6% of greenhouse gas emissions, according to a key paper on this topic, published in 2020 in Health Affairs. In the United States, the toll is particularly heavy. It’s estimated that the health care sector produced about 8.5% of domestic greenhouse gas emissions in 2018, according to that paper. It also notes the U.S. medical system may be responsible for about a quarter of all global health care greenhouse gas emissions, which is more than the health care system of any other nation."
