Climate change poses an imminent threat to environmental and public health. Despite recent efforts to decrease our carbon footprint, the United States remains one of the highest contributors to this problem, ranking second in greenhouse gas emissions and energy usage worldwide.1,2 Health care alone accounts for nearly 10% of this energy expenditure.2 Within hospitals, operating rooms (ORs) produce a disproportionate amount of greenhouse gases and disposable waste and consume an inordinate amount of energy. Recent studies attribute more than 30% of hospital medical waste to ORs and estimate their energy intensity, defined by amount of energy used per occupied space, to be 3 to 6 times that of a hospital in its entirety.3,4
