Getting Beyond Polarization on Climate

In this episode, Chris and Mark speak with Robert (Bob) Eccles , godfather of the sustainability disclosure movement, Oxford professor, and so much more. The interview builds off an exploration of Bob's most recent book, An American's Guide to Climate Change: How America Can Lead and Prosper. Bob wrote the book for the vast majority of Americans on the left and right who recognize climate change impacts and want something done—the book outlines what and how. From that base, the conversation extends to explore how climate change is a growing part of right-wing politics, especially for younger voters, and the different kinds of solutions they favor. Bob also opines on the state of corporate sustainability disclosure and its likely path forward, then closes with some unique advice for listeners.
