According to Practice Greenhealth, an organization for sustainable health care, operating rooms drive up to 60% of a hospital’s revenue while producing more than 30% of its waste, and two-thirds of its regulated medical waste while consuming three to six times more energy per square foot than anywhere else in the facility.

  • The medical center has achieved a 65% reduction of anesthesia-related greenhouse gas emissions (from a 2018 baseline) across the health system.
  • At ambulatory surgery locations, we reduced the amount of air exchanges during unoccupied times in the operating rooms during evenings and weekends, which has saved up to 50% of the energy loads in those spaces.
  • Operating rooms at Ohio State’s Eye and Ear Institute and at The James started a pilot program to collect clinical plastics for recycling, diverting 2.5 tons in fiscal year 2023.

Greenhouse gas emissions per anesthetic agent from baseline

Agents shown are sevoflurane, isoflurane and desflurane. Each year shows a steady decline in greenhouse gas emissions.
