This episode explores the future of the Green Movement through two rival visions: Zach Polanski’s eco-populism, which links climate action to social justice, and Lord Deben’s market-based approach. Set against a backdrop of political shifts and the 2025 Green Party leadership election, the discussion highlights the struggle to maintain consensus on net zero amidst rising climate fatigue. Host Justin Rowlat examines how environmentalism is evolving from a scientific imperative into a complex political battle over fairness and economic strategy.
