Understanding the problem is only the first step. Real change happens when ideas become actions.

Professor Pedro Povoa shares his experience leading sustainability initiatives within his university hospital. Across the world, more hospitals are creating "green teams"—multidisciplinary groups dedicated to reducing waste, improving resource use, and embedding sustainability into everyday practice.

What does a successful green team look like? Who should be involved? Can environmental initiatives coexist with excellent patient care? And where should ICUs begin if they want to start their own sustainability journey?

Through practical examples and lessons learned, Prof Povoa demonstrates that meaningful change often starts with small, achievable steps.
