Zack Polanski is challenging the notion that you can’t be Green and a popular politician. Since he became the leader of the UK’s Green Party in September 2025, he has run a campaign that’s pushed his party ahead of the incumbent Labour Party and opposition Conservative Party in some polls. It’s a remarkable rise in a short span of time – how did he pull it off and what will he do if the Green Party gets into power?

As the war with Iran drags out and oil prices remain turbulent, it raises the question of whether — and how — prolonged conflict in the Middle East might impact global fossil fuel dependence and the future of renewable energy.

This week on Big Take podcast, Bloomberg reporter Todd Woody and Zero podcast host Akshat Rathi join Sarah Holder to discuss early signs that the high cost of oil is reigniting consumer interest in electronic vehicles and other clean energy technologies, and how companies and countries are beginning to respond.

The United Nations Intergovernmental Panel on Climate Change is responsible for collating our shared scientific understanding of how global warming is impacting the planet. But the body now faces a challenge after the US withdrew funding for its scientists to participate. Professor Jim Skea, who chairs the IPCC, joins Akshat Rathi on Zero to talk about the body’s future, whether the organisation can survive the US pullback, and what questions the next set of reports are going to answer.

Many consider a widespread war in the Middle East the worst-case scenario for the global oil and gas markets. That war is here, and it could have wide-ranging, long-lasting impacts on energy and climate policy. This week on Zero, Akshat Rathi speaks with Jason Bordoff, director of the Center on Global Energy Policy at Columbia University and former energy and climate advisor to President Barack Obama to try to understand what those impacts could look like. Will countries double down on fossil fuels or will they speed up the clean-energy transition?

Societal collapses happen more often than you think, and there’s much we can learn from the past to avoid or, at least, delay another one.

This week’s guest on Zero is Luke Kemp, author of Goliath's Curse, which draws lessons from the rise and fall of societies over 5,000 years of human history. Akshat Rathi asks Luke whether our current moment — with climate change and AI — makes us uniquely vulnerable to societal collapse or more resilient than we might think.
