At COP28 in December 2023, the world committed to transitioning away from fossil fuels. Yet in the years since, there’s been little progress. A meeting in Colombia last month hoped to change that, gathering ministers and climate envoys from 57 countries to try and chart a path to end the use of fossil fuels. This week on Zero, Tzeporah Berman, chair of the Fossil Fuel Non-Proliferation Treaty Initiative, tells Akshat Rathi what the conference achieved and where it goes next.

Reform UK is currently the most popular party in Britain. If voted into government, it wants to end all subsidies for renewable energy, ban battery energy storage, end net-zero targets, drill for more oil and gas in the North Sea and encourage fracking on British soil.

This week on Zero, Akshat Rathi asks Reform’s deputy leader Richard Tice about the party’s climate and energy plans, and why he calls it “net stupid zero.”

This week on Zero, Akshat Rathi talks with Gerald Butts, chairman of the political risk consultancy Eurasia Group and former chief of staff to Prime Minister Justin Trudeau.

Everywhere you look, you see two types of technology existing side-by-side. One that runs on fossil fuels and one that runs on clean electricity. There’s an ongoing struggle between the two, a tug of war between two very different futures. Some call it the mid-transition, and it comes with costs that make it politically fraught. This week on Zero, Emily Grubert, professor of sustainable energy policy at the University of Notre Dame, tells Akshat Rathi how to navigate the mid-transition, and the better energy system that exists on the other side.

We are living in an increasingly divided world. It took two decades to get to the Paris Agreement, and then global cooperation really lasted only for a decade. One key reason for this fragmentation is US President Donald Trump, who has taken an axe to the rules-based international order that America helped build. This week on Zero, Gordon LaForge, senior policy analyst at think tank New America, tells Akshat Rathi what comes next, and how progress can still be made on climate.

Sadiq Khan is about to complete 10 years as London’s mayor. He’s seen the city affected by Brexit, the pandemic and two energy crises. That hasn’t deterred him from deploying some of the strongest air-quality regulations in any city. But he hasn’t yet succeeded in getting enough homes built and struggled to keep improving the train network. As cities keep growing, Khan talks to Akshat Rathi about lessons from London’s successes and failures. As a prominent member of the UK’s Labour Party, Khan also shares his thoughts about the future of the party. The interview was recorded on April 16.

In the past month, we've seen two major plans from two of the world's biggest polluters. In March, China approved its 15th five-year plan, which gave us a clearer sense of how the government makes progress on its climate goals. A few weeks after that, India published its climate plan for 2035. This week on Zero, Bloomberg Green’s Lili Pike and Akshat Rathi discuss those climate plans, and whether they’re ambitious enough for the current moment.

Since the US and Israel launched their attacks on Iran on Feb. 28, global energy markets have been frenetic, prices swinging up and down with each new headline. Even with the prospect of the Strait of Hormuz reopening, prices of oil and gas have risen around the world, and we’re starting to see impacts on local economies, particularly in Asia. This week on Zero, Bloomberg opinion columnist David Fickling explains what those impacts are, and how they may reshape Asia’s energy systems for decades to come.

We're dropping into your feed with a special episode featuring Akshat Rathi, who joined us to discuss why the Iran war is making a new argument for renewable energy.

The war in the Middle East has roiled oil and gas markets. The unrest and price spikes are making countries look again at renewable energy like solar and wind — produced at home and insulated from external tensions. But experts warn that the picture is more complicated.

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?
