In 2019, a group of law students from Pacific island nations set in motion a case that made it to the world’s highest court: The International Court of Justice. The students wanted answers to two important questions: what responsibility do countries have to stop climate change? And if countries don’t stop polluting, will they have to pay for the damages? Now the ICJ has delivered its verdict, and it seems like a huge win for the climate. But is it? Laura Clarke, chief executive officer of legal non-profit ClientEarth, joins Akshat Rathi on Zero to discuss.

Everywhere you look, it seems like bad news for climate tech. Investments are down, the US government has cut incentives and startups are running out of cash. But venture capitalist Vinod Khosla is still bullish, even though the One Big Beautiful Bill cut an estimated $500 billion in green spending. This week on Zero, Akshat Rathi speaks with Khosla to find out when we can expect to see fusion, whether he’s reconsidering investing in the US and why he still thinks the best clean tech is yet to come.

The One Big Beautiful Bill Act cuts almost $500 billion in US clean-energy spending, just as the country was starting to get serious about its climate goals. Some say the country is acting like a petrostate, waging war against clean energy. Others are more sanguine and believe that the US will stay the course in the long term. This week on Zero, Akshat Rathi is joined by Jigar Shah, a clean energy expert and former head of the Department of Energy's Loan Programs Office, to make sense of the bill’s impacts, and whether it’s as bad for climate as it seems.

This week, we explore how the legislation’s attack on renewable energy may push up electricity bills and damage US competitiveness in AI.

The tax credits in President Joe Biden’s sprawling Inflation Reduction Act were introduced to help the US keep up with rising electricity demand by making clean power sources cheaper. But now the big bill has changed all that, and an executive order issued days after its passage suggests his war on renewables isn’t over yet.

Joining host Stephanie Flanders to discuss this dramatic turn of events are guests Ethan Zindler, head of country and policy research at BloombergNEF and previously climate counselor to US Treasury Secretary Janet Yellen, and Bloomberg lobbying and influence reporter Emily Birnbaum.

The world’s militaries are incredibly polluting, collectively accounting for some 5.5% of global emissions. Western economies are now gearing up for a big expansion of their militaries, with members of the North Atlantic Treaty Organization (NATO) agreeing to increase defense spending to 5% of their gross domestic product by 2035. That will commit trillions of dollars more to an enormously carbon intensive industry, unless militaries can find a way to reduce their emissions. This week on Zero, Akshat Rathi asks retired Lieutenant General Richard Nugee, author of the UK Ministry of Defence’s climate change report: Can warfare go green?

When the UK handed the Labour party a parliamentary majority last July, it promised to build a new state owned energy company called Great British Energy. It's almost exactly one year since its creation, and GB Energy now has a budget of £5.8 billion to get the organization off the ground. It sounds like a lot of money, but is it? And what exactly will the organization do with all of it? On Zero this week, Akshat Rathi spoke to Dan McGrail, interim CEO of GB Energy, to find out the answers.

Climate tech is not the hot investor thesis it once was a couple of years ago. After several record breaking years, and billions of dollars being poured into climate startups, venture capital investments are way down. This week on Zero, Akshat Rathi speaks with Mike Schroepfer, who runs Gigascale Capital, a venture firm focusing on climate investments, and used to be Meta’s chief technology officer. Schroepfer shares his views on the current investment climate, the danger of funding cuts to US research, and why demand for AI will prompt a new wave of energy innovation.
