Post-pandemic world needs a different approach to future global challenges. During Covid times, we proved that united we are stronger and surgeons are key-positioned to lead a greening change in the operatory room. The paradox is that operatory rooms are at the same time places of highest care for patients and sources of pollution and thread for the planet. Creating a Green Team in your hospital would provide the tool to drive the change. New good practiced could easily be proposed and introduced to reduce the flow of waste production and the negative impact on the environment. The top priority is to share awareness on this problem and induce a cultural transformation to the new generation of surgeons.
