In the first episode of our two-part World Mayors Summit special, we heard from mayors around the world about the power of convenings like the Summit to unite city leaders and spark collaboration. In this second episode, we explore what that collaboration looks like in practice, from new approaches to urban planning and the challenge of energy-hungry data centres, to fossil-free trucks and greener and cleaner shipping routes.

We also explore the outcomes for cities that came out of COP30 with voices from people who were on the ground in Belém…and also from a Brazilian climate leader who had a front-row seat before, during, and after what many have been calling the most important COP since the Paris Agreement.
