In this episode of Crossing Channels, Richard Westcott talks to Dr Alessio Terzi from the Bennett School of Public Policy, and Prof Christian Gollier from the Toulouse School of Economics, about what a “fair” climate transition could look like when the costs are local, the benefits are global, and the politics are hard.

They explore why decarbonisation is a whole-economy transformation, what it means for jobs and places, and why the narrative matters as much as the technology.

The conversation also looks at carbon pricing and redistribution, the credibility problem of long-term policy, and what kinds of institutions and policies can keep people on board in the years ahead.
