This podcast is produced by Leaf Media and powered by Greenly. 🌱Interviewed by Ben Stimpson-Wood, Greenly’s UK Climate Engagement Manager.

In this episode, @Ben speaks with @Imogen, Head of Sustainability Education and Implementation at Great Ormond Street Hospital (GOSH), to explore how GOSH and the NHS is confronting the climate crisis—a battle the World Health Organization calls the greatest health threat of the 21st century.

A former critical care nurse turned sustainability pioneer, Imogen shares her journey from bedside care to shaping national NHS strategies. She reveals why healthcare professionals are on the frontlines of climate action, and dives into how GOSH—the first London hospital to declare a climate emergency—is turning net-zero ambitions into reality.

Tune in to discover how the UK's largest workforce–1.5 million NHS staff members–is mobilizing for the planet.
