How can we build a more united climate movement? What should be the role of geoengineering? And how can indigenous voices be brought into the climate conversation? Bryony puts these questions to model, actor, director, ambassador and businesswoman, Lily Cole.

Welcome to season 12 of Cleaning Up! If you want a sense of the trajectory of climate action, you have to understand China, and you have to understand finance. There is no one better to share insights on both than Dr Ma Jun, Founder and President of the Institute of Finance and Sustainability in Beijing.
