By removing high-emissions anesthetics from operating theatres and implementing low-flow anesthesia machines, Raigmore Hospital significantly reduced emissions produced by their operating theatres. This initiative was implemented as a part of the Green Theatre Project, which consists of 11 actions to make operating theatres more sustainable. The project was so effective that it was integrated into the NHS Scotland climate emergency and sustainability strategy for 2022 through 2026 as the national green theatres program.
