World leaders are flocking to Beijing. In the first weeks of 2026, Canada’s Mark Carney, the UK’s Sir Keir Starmer and South Korea’s Lee Jae-myung have all made high-profile visits - an unmistakable signal of global power recalibrating.

China’s dominance in clean energy manufacturing is already well established: from solar panels and batteries to wind turbines. The question now is whether this transition remains merely made in China, or whether it is increasingly being shaped and led from Beijing.

Christiana Figueres, Tom Rivett-Carnac and Paul Dickinson consider what this shift may mean for the future of climate leadership - and for the institutions, alliances and norms that have shaped global climate cooperation for decades. They’re joined by scholar of China’s political economy and climate governance Yixian Sun, who has recently advised the UK government on their engagement with China. He unpacks the country’s own vision of leadership, its evolving role in the Global South, and the risks and opportunities of an increasingly multipolar climate order.

As the world recalibrates around China’s growing role, how does Beijing see itself? And what are other governments actually seeking as they turn towards it? We spoke to the man advising the UK government ahead of Keir Starmer’s arrival in Beijing.

How dependent are we - economically, politically and socially - on fossil fuels? And how do we begin to loosen that grip?

As the world reels from geopolitical shocks, multilateral institutions under strain, and the United States’ withdrawal from key climate bodies, Ana Toni - CEO of COP30 - joins the show to discuss what comes next. Both for Brazil’s presidency in this crucial year, and for the wider system of climate cooperation at a moment when the old rules feel increasingly fragile.

Christiana Figueres, Tom Rivett-Carnac and Paul Dickinson ask Ana what was achieved in Belém, what fell short, and why the year after the COP may matter more than the summit itself.

Are we entering an era where progress is driven not by universal agreement, but by those willing to move first and bring others with them? And could reframing the transition around ending dependence, rather than negotiating targets, change the politics of climate action?

What happens when the world’s most powerful country walks away from the system it helped to build?

This week, we examine the United States’ decision to withdraw not only from the Paris Agreement, but from the UN Framework Convention on Climate Change itself - alongside dozens of other international bodies. Headlines declared the end of multilateral climate cooperation. But is that really what this moment represents?

Christiana Figueres, Tom Rivett-Carnac and Paul Dickinson unpack what has actually been announced - and what it does (and doesn’t) change in practice.

They are joined by Sue Biniaz, former US Deputy Special Envoy for Climate Change and one of the quiet architects of decades of climate diplomacy. Sue brings rare insight into whether a US president can legally withdraw from a Senate-ratified treaty, the surprising pathways by which a future administration could rejoin, and what influence the US may still wield as a non-party.

Could the absence of the US voice, paradoxically, unlock progress elsewhere? And in a fractured world, where does collective climate leadership now come from?
