Fatalism. Apathy. Cynicism. Deprioritisation. Hostility. Cost. Gridlock. When green campaigners and politicians lose the debate, this is why. Now, the Mayor of London draws on a decade in the corridors (and cycle lanes) of power to explain how, in practice, to win the climate argument. His book will help create a world where we can all breathe again.
