The Trump administration last week announced the repeal of the ‘endangerment finding’ - the 2009 determination that climate change threatens public health and welfare. It may sound arcane, but this piece of legislation empowered the US federal government to regulate greenhouse gas emissions. This decision weakens the regulatory backbone of American climate policy, and may reshape the country’s emissions trajectory for years to come.

So what happens next?

This week, Christiana Figueres, Tom Rivett-Carnac and Paul Dickinson consider the politics, the economics and the climate reality of this move. And Tom calls friend of the show Manish Bapna, President and CEO of the Natural Resources Defense Council, whose organisation is preparing to challenge the rollback in court. Speaking to us just as the case was filed, Manish explains why the endangerment finding has long been the legal bedrock of federal climate action, and how the case could climb all the way to the Supreme Court.

Until then, uncertainty reins: is this a temporary political detour - or a structural turning point for US climate leadership? And if federal authority falters, will states, businesses and markets keep the transition moving anyway?

Who shapes climate action when old systems begin to strain? And where does power really sit - with governments, financial institutions, communities, or individuals?

Christiana Figueres, Tom Rivett-Carnac and Paul Dickinson explore climate leadership in a more fragmented geopolitical moment. Picking up the threads from last week’s episode, they ask what happens when multilateralism is threatened - and whether smaller coalitions, subnational actors and civic movements are already stepping in to fill the gap.

Because with great challenges, come new opportunities. What might we gain from faster, more focused alliances? Might Indigenous wisdom provide lessons for building fairer, greener economic models? And how can we use the resources we have to support Brazil’s vision for a global mutirão?

Who really holds power in the climate transition? And how do money, politics, and influence shape the pace of change?

In this episode, Christiana Figueres, Tom Rivett-Carnac and Paul Dickinson use some of your most probing questions on the political economy of climate action to unpack what happens behind closed doors and to challenge some of the assumptions that often dominate public debate. 

What does lobbying actually look like - and is it always a bad thing? What are we talking about when we refer to ‘fossil fuel subsidies’? And in an age of populist politics and shrinking attention spans, can complex climate solutions still cut through? Or are we drifting toward simpler narratives that are easier to sell, but harder to govern?

From negotiation rooms to national politics, and the economic systems beneath them, these are the forces both loudly and quietly shaping climate progress. And if we want to accelerate action, we first have to understand where power truly sits.

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?

The year has barely begun, and already the fault lines of global power are on full display.

Christiana Figueres, Tom Rivett-Carnac and Paul Dickinson take stock of a moment that feels both shocking and revealing. The US abduction of Venezuela’s president raises urgent questions about sovereignty, international law, and the enduring grip of fossil fuels on geopolitics - even as the energy transition accelerates. But what’s really driving events in Venezuela? And how can we tease apart the political theatre from the realities of oil markets, military power, and domestic US politics.

Later, we ask: what are the big themes, underlying trends and climate stories already shaping the new year? From the possible rise of left-wing populism, to the intensifying battle over who will become the next UN Secretary-General.

As 2026 begins, the question is not just what kind of year lies ahead for climate action, but what kind of global order will shape it.

As billions around the world mark the beginning of a new year, many are pausing to ask the same questions: what do we carry forward, and what do we leave behind, as we cross from the old into the new? And as headlines fill with predictions about the rise of artificial intelligence, could a different kind of AI - ‘ancestral intelligence’ - offer insights equal to the depth of the climate and biodiversity crises we now face?

This year’s COP saw Indigenous and First Nations Peoples better represented than ever before; but it also showed how far there is still to go to include them in meaningful dialogue. In a conversation recorded at COP30, Christiana Figueres sits down with two Indigenous leaders from different continents and traditions: Mindahi Bastida, from the Otomí-Toltec peoples of Mexico, and Atawévi Akôyi Oussou Lio, Prince of the Tolinou people of Benin. Together, they explore a relationship with the living world grounded in belonging rather than dominance, continuity rather than short-termism, and reciprocity rather than extraction.

Tom Rivett-Carnac and Paul Dickinson then join Christiana to reflect on what it means to carry this wisdom into the year ahead. And if the challenges before us are not only technical and political, but also cultural and spiritual, how might that reshape the way we act, decide, and lead in 2026 and beyond?

At a moment when the world feels noisier, faster, and more demanding than ever, what role can beauty play in helping us slow down, reconnect, and remember what matters?

As the year draws to a close, Christiana Figueres, Tom Rivett-Carnac and Paul Dickinson step back from targets, timelines and political headwinds to explore how craft, design and the quiet appreciation for our objects and spaces can shape both the worlds we live in, and the futures we are trying to build.

Tom is joined in Bath by designer and artist Patrick Williams, founder of the design studio and workshop Berdoulat, whose work is rooted in traditional craft, natural materials and a deep sensitivity to place. Together they reflect on what happens when efficiency crowds out care, when buildings and objects lose their connection to human bodies and natural rhythms, and why the climate crisis may also be a crisis of beauty.

As we reflect on a challenging year for climate action, we also offer an invitation for the days ahead: to slow down, to notice what restores us, and to remember that meaningful change is sustained not just by effort, but by care, beauty and joy.

At the very moment we need clarity and trust, information integrity is being polluted. Disinformation is profitable and the impact on truth is dangerous. Nowhere is this more obvious than in the discourse around climate.

This week, Outrage + Optimism steps into the murky, fast-moving world of climate disinformation. Not simply misunderstanding and confusion, but the deliberate shaping of narratives to delay action, fracture trust, and profit from doubt.

Christiana Figueres, Tom Rivett-Carnac and Paul Dickinson explore why disinformation is accelerating just as the climate stakes are rising, how it feeds on human psychology, and why the erosion of shared facts may be one of the greatest barriers to collective climate action.

Paul brings us a conversation from COP30 with Jake Dubbins, a leading voice at the intersection of advertising, climate and human rights. Together they unpack how fossil fuel advertising, opaque algorithms and the attention economy are shaping what we see, what spreads, and what stalls climate action. And they examine the newly launched Declaration on Information Integrity on Climate Change, a first-of-its-kind effort at the international level.

But can governments, platforms and advertisers clean up a poisoned information space without sliding into censorship? And where should the line really be drawn between free expression and preventing harm?
