COP27 takes place amid war in Ukraine and an energy crisis. In the third episode of our series covering the summit, we explore how energy-security concerns are affecting efforts to decarbonise.

Niklas Höhne of the NewClimate Institute says the energy crisis could deepen Europe’s dependence on fossil fuels. But Francesco La Camera, who leads the International Renewable Energy Agency, sees it as an opportunity to accelerate the green agenda. Plus, award-winning author Daniel Yergin explains the implications for Russia, and Jason Bordoff of Columbia University assesses the geopolitics of the transition to clean energy.

Alok Jha hosts with Catherine Brahic, The Economist’s environment editor, and Vijay Vaitheeswaran, our global energy and climate innovation editor.
