This week, John Higginson speaks with Rosamund Kissi-Debrah CBE, whose daughter Ella became the first person in the world to have air pollution listed as a cause of death.

Since then, Rosamund has led a relentless campaign for cleaner air — not just in London, but across the UK and beyond. She talks about what it takes to turn personal tragedy into lasting change, the links between pollution and health, and why she believes clean air should be treated as a basic human right.

It’s a moving, clear-eyed conversation about accountability, children’s health, and the cost of doing nothing.

I hope you enjoy.
