Both the IEA and BNEF now project that current policies put us on track for roughly 2.5°C of warming. Some voices, like Daniel Yergin and Bill Gates, argue we should accept that trajectory and focus only on the technologies that are already winning. But even 2.5°C is still much too high. We can and must do better.

To help us take stock of the global energy transition in today’s conversation, we are fortunate to be joined by Lord Adair Turner, co-chair of the Energy Transitions Commission (ETC), headquartered in London. The Commission is a global coalition of major power and industrial companies, investors, environmental NGOs, and experts working on achievable pathways to limit global warming while stimulating economic development and social progress. Lord Turner chaired the UK Climate Change Committee from 2008 to 2012, chairs insurance group Chubb Europe, and is a crossbench (non-partisan) member of the House of Lords.

We discuss how the transition is reshaping geopolitics, why the ETC’s forecasts for green hydrogen have been cut roughly in half, and what Europe’s green industrial policy (including its carbon border adjustment mechanism) needs to get right. We explore the roles of China and the UK in mobilizing capital for the developing world, how the UK has achieved a 75% decarbonization of its power sector in just 14 years, and what Turner calls ‘double banking’ — the core challenge of the mid-transition, where we’re paying to build new energy systems while the old ones can’t yet be switched off.

Turner makes the case that well below 2°C is still achievable, but only if we return to the climate imperative alongside the technological opportunity.
