As healthcare systems continue their bid to “first, do no harm,” more attention is being placed on the organizations’ broader impact on their communities, including the environment and air quality.  It is estimated that the global health care industry is responsible for two gigatons of carbon dioxide each year, or 4.4% of worldwide net emissions.  And according to a September 2019 report by Health Care Without Harm, over half of the industry’s emissions (representing an estimated 2.2% of the worldwide net emissions) can be attributed to the health care industry’s use of energy. The energy-intensive nature of the industry correlates with the often 24/7 use of health care facilities and the high-tech, life-saving equipment.
