Zero: The Climate Race

When Canada elected Mark Carney as prime minister, there was hope that the country would pursue climate policies. That hope was crushed after Carney signed a deal with the oil-producing province of Alberta that will roll back or dilute green regulations. 

As a result, Steven Guilbeault, Carney’s culture minister has resigned from cabinet. He was the environment minister under Justin Trudeau and responsible for many of the policies at risk. This week on Zero, Guilbeault tells Akshat Rathi why the Alberta deal was the last straw.

Climate leaders from around the world have convened in Baku, Azerbaijan for the UN’s biggest annual climate conference, COP29. And this year, it’s all about money. 

Member nations are negotiating over how much responsibility rich countries have to finance the energy transitions of smaller economies. But larger global tensions loom over the proceedings — including the reelection of Donald Trump.

In this episode of the Big Take, Bloomberg’s senior climate reporter and host of Zero Akshat Rathi calls in from COP29 to update host Sarah Holder on the unfolding negotiations and how America’s new presi...

Reporter Akshat Rathi sits down with ExxonMobil CEO Darren Woods, who made his second-ever appearance at the United Nations climate conference. Woods made the case for why incoming US president Donald Trump shouldn’t exit the Paris Agreement, and should uphold the country’s monumental climate legislation passed under the Biden administration. It’s quite the tone shift for a company that has a well-documented history of sowing doubt about the dangers of global warming.

Zero is in Baku, Azerbaijan, where delegates and heads of state from around the world have gathered for COP29.  Can a petrostate make a summit on decarbonization a success? And how much will the election of President Trump damage the US’s credibility on climate– and set negotiations back? Akshat Rathi tells producer Mythili Rao what’s in store in the two weeks ahead, and COP29 President Mukhtar Babyaev explains how Azerbaijan is trying to make the summit a success, despite concerns that NGOs and protesters will have limited access to the proceedings. Plus, Columbia University’s Jason Bordoff explains...

Donald Trump’s re-election as the US president drastically changes the climate and energy equation—in the US and around the world.

In fractured times, what does it take to reach agreement? That’s the question writers Joe Murphy and Joe Robertson set out to explore in a play about the drama of climate negotiations. Kyoto, which ran at the Royal Shakespeare Company’s Swan Theater in Stratford-upon-Avon this summer, tells the story of the 1997 Kyoto Summit as seen through the eyes of Don Pearlman, a notorious fossil fuel lobbyist and chain-smoking lawyer dubbed “the high priest of the Carbon Club” by der Speigel. Actor Stephen Kunken, who plays Pearlman, tells Akshat Rathi why he was drawn to the character, and what Kyo...

Started as a battery company in the 1990s in Shenzhen, BYD is now one of the best-selling EV brands in the world. Once mocked by Elon Musk, the company’s startling growth made it a global player and has sparked tariffs in the US and EU. In this episode of the Big Take Asia Podcast, host K. Oanh Ha talks to Bloomberg’s Gabrielle Copolla and Danny Lee about the company’s aggressive expansion and what it means for the global auto market.

As Republican and Democratic canvassers make their final push to get out the US vote, the famed tech investor Vinod Khosla has been making the case for Vice President Kamala Harris with a very specific audience in mind: Elon Musk. On the social media platform owned by his fellow billionaire, Khosla has pressed the case in a series of X posts that former President Donald Trump is the wrong candidate for the future of the planet. Although Khosla is a former Republican, he says in an interview that he will be voting for Harris. But he doesn’t expect te...

Electric vehicle sales have hit the brakes in Europe and the US in recent months, as cost-conscious drivers have opted for cars with exhaust pipes instead. Bucking the trend is ride-sharing giant Uber, which is not only adding zero emission models to its fleet, but also lobbying regulators to demand more EVs on the road. On Zero, Dara Khosrowshahi discusses the company’s short and long-term green goals, and tells Akshat Rathi why he believes electric cars are good for business – not just for the environment. He also discusses autonomous cars, flying taxis, carbon accounting and what a just tran...

As Florida reels from the impact of Hurricane Milton, some Wall Street investors appear to be on track to profit from catastrophe bonds tied to the storm’s outcome. Cat bonds are a specialized insurance tool that can help people who've lost their homes find money to rebuild– or deliver big profits to investors who are willing to gamble on big natural disasters. As Bloomberg’s Gautam Naik has reported, last year cat bonds were the most profitable strategy for hedge funds. Naik tells Akshat Rathi about how these financial instruments differ from ordinary insurance, and why they have become...

Next month, when delegates from around the world meet in Baku, Azerbaijan at COP29, the biggest questions on the table will have to do with money. Can rich nations find a way to meet developing countries’ demand for up to $1 trillion each year in climate finance? Avinash Persaud, special adviser on climate change for the Inter-American Development Bank, has spent his career looking for ways to make global markets work to unlock climate financing. He says the biggest challenges arise from a simple reality: “The people who benefit and the people who pay are different.” Persaud tells Akshat Rathi why he...

What if major economies all just agreed to quit fossil fuels  — together? To date, 13 countries have signed a fossil fuel nonproliferation treaty. The biggest is Colombia, which has a $40 billion economic transition plan to build up green sectors and replace oil and gas revenue. Now Colombia is hoping to recruit other large economies to follow suit. 

During a conversation at Climate Week in New York, Akshat Rathi sat down with Colombia’s environment minister, Susana Muhamad, and Brazil's chief climate negotiator, Liliam Chagas, to talk about what it will take for more nations to combat climate change. Brazil...

Scientists have been trying to understand — and mimic — the way the sun produces energy for centuries. But recreating the energy-generating process of nuclear fusion here on Earth presents an array of technical challenges. Bob Mumgaard, CEO of Commonwealth Fusion Systems, began working on some of those challenges as a doctoral student at MIT. Now backed by more than $2 billion, CFS is well on its way to making the long-held dream of nuclear fusion a reality. On this week’s Zero, Mumgaard breaks down the science behind CFS’s bagel-shaped tokamak reactor, and explains why he believes the nuclear fusion industry...

In a little more than six weeks, Americans will cast their votes in a presidential election that has enormous stakes for the future of the planet. This week on Zero, Akshat Rathi sits down with energy and environment reporter Jen Dlouhy to talk about how Kamala Harris could advance US climate policy — and how Donald Trump could chip away at it.  “Starting on day one, he's already said he intends to direct federal agencies to begin repealing and replacing climate regulations,” she says.

At this stage of the campaign, Harris’s plans are still somewhat opaque. But if electe...

Weather patterns have always had an impact on people and civilizations. Historians argue that El Niño may have contributed to the French Revolution, and climate variability could have led to weakening the Ottoman Empire. But as anthropogenic emissions make the planet hotter, faster, Berghof Foundation Executive Director Andrew Gilmour says the risk of conflict is growing. In the 30 years he spent working with the United Nations, Gilmour repeatedly saw how competition over resources such as land and water led to conflict, but he also sees opportunities for aligning peace-building with climate solutions. “The common solutions could be, for exa...

After years of research and development and billions in investment, autonomous flying taxis are finally poised to take off. Companies working on these pilotless vehicles have been quietly working on prototypes. In this bonus from The Big Take, Bloomberg reporter Colum Murphy takes a test flight in one of the first models operating in China, and his colleague Angus Whitley explains why it’s a make or break moment for the industry.

Plus: Hear a past episode episode of Zero about flying cars with Venkat Viswanathan, a professor at Carnegie Mellon University who has been working to cr...

Achieving net-zero carbon emissions is a massive challenge for every industry, but some have it harder than others.  This week, Bloomberg Green senior reporter Akshat Rathi spoke with two Australian startups that are tackling carbon emissions in sectors whose carbon footprints are particularly intractable. Inspired by shark skin, MicroTau is creating a plastic film that makes airplanes more aerodynamic, reducing their fuel consumption.  Novalith, meanwhile, is redesigning lithium battery  manufacturing to make it cleaner. Both have received funding from the Clean Energy Finance Corporation in Australia. Rathi sat down with MicroTau founder Henry Bilinsky and Novalith Chief Executive Officer Ste...

Before he founded the geothermal startup Fervo in 2017, Tim Latimer was a drilling engineer for the oil and gas industry — a job he loved. “Honestly, if it wasn't for climate change, I probably wouldn’t have ever changed my career,” he says this week on Zero. Now Latimer is applying his drilling know-how to Fervo’s wells, supercharging their energy production in the process. The company opened its first power plant in Nevada late in 2023, and is now in the process of opening another plant in Utah. Latimer and Akshat Rathi chat about opportunities in geothermal, the infernal permitting process, a...

The “cold chain” that delivers our food is inconspicuous but vast. The US alone boasts around 5.5 billion cubic feet of refrigerated space; that’s 150 Empire State Buildings’ worth of freezers. Now, the developing world is catching up. On Zero, Nicola Twilley, author of Frostbite: How Refrigeration Changed Our Food, Our Planet, and Ourselves, discusses how refrigeration became so ubiquitous and what our reliance on it means for our palates and the planet.

This week on Zero, reporter Akshat Rathi sits down with Renee Salas, an emergency medicine physician at Massachusetts General Hospital and Harvard Medical School and a leading expert on the health impacts of global warming. The intersection of health and climate change is a growing area of research, and an increasingly urgent one: Heat deaths among seniors, for example, are projected to increase 370% by mid-century.  But even the young and relatively healthy are at risk. “The take-home I want everyone to go away with is that we all are at risk for this,” Salas says, “especially as we get into mo...

Upgrading the grid for a net-zero world isn’t just a matter of building new infrastructure. Yes, miles of additional cables will be needed, as will more transformers, more substations and more engineers and technicians. But plenty of existing technology will also need to be updated. On the third episode of Zero’s grid series, TS Conductor founder Jason Huang discusses the material science breakthroughs that have enabled his company to create cables that have twice the conductivity of existing cables — and just as much strength.

As the world moves away from fossil fuels, the electricity grid will need to be able to handle a greater and greater load. In the second installment of Zero’s grid series, Akshat Rathi sits down with Scottish Power CEO Keith Anderson to talk about what that looks like in the UK. They discussed the promise of GB Energy, the challenges of hiring qualified engineers, and what the new Labour government can do to speed up the UK’s energy transition.

Even before we turn on a light switch or plug an appliance into an electric outlet, the atoms that power our daily life have traveled a long journey across the grid to reach our homes. And to meet the demands of a net zero future, that grid will need an upgrade. BloombergNEF analysis estimates that the world will need to nearly double its grid network to 111 million kilometers– a distance almost three quarters the way to the sun– by 2050. How will we get there?  Former BNEF grid expert Sanjeet Sanghera, who is now working on strategic futures at the Natio...

Lucie Pinson is a climate activist focused on the banks that fund fossil fuel projects. But she doesn’t march, chant, picket corporate headquarters, or glue herself to the road. Instead, she and her team at the Paris-based nonprofit Reclaim Finance get to know Corporate Social Responsibility officers, trawl through company statements and portfolios, and join shareholder calls. Reclaim Finance’s strategy is all about finding ways to pressure big financial institutions from the inside– and it works. She tells Akshat Rathi about some of the successes her organization has had, and why even bank employees who don’t care abo...

At the Bloomberg Green Festival, Akshat Rathi sits down with voting rights advocate Stacey Abrams and Ari Matusiak, who leads the nonprofit Rewiring America. Together, Abrams and Matuisiak are trying help middle and low-income families access the tax breaks that can help them affordably electrify their homes. They discussed why household emissions are such a big deal, how to connect existential questions about the future of the planet to kitchen-table decisions, and whether Joe Biden is still the right Democratic candidate for 2024.

Tackling climate change now requires not just reducing planet-warming emissions to zero, but also finding a way to draw down existing carbon dioxide from the air. Over the past few years, tech companies have taken the lead to seed hundreds of startups that want to sell carbon removal credits and help companies meet climate goals. But the failure of a major startup, Running Tide, has raised questions about the long-term viability of the market. This week on Zero, we hear from Nan Ransohoff, head of climate at Stripe, and pioneer of the carbon-removal market.

Earlier this month, tech billionaire Bill Gates broke ground on a new nuclear plant in Kemmerer, Wyoming– a historic coal town. Gates tells Zero why he hopes the plant, which uses sodium for cooling, rather than water, will be the first of many in the country– no matter who wins this year’s election. “The idea of the US being more energy secure and US innovation allowing us to export, those things are still somewhat bipartisan in nature,” he says. Plus, he weighs in on AI as both a major generator of emissions and as a potential source of climate so...

We are living through the hottest year on record. That’s not news, but growing climate impacts make bigger and bigger news. At 1.3C of warming beyond pre-industrial levels, people are reckoning with a planetary system that’s out of whack. It’s not like the scientists didn’t see worsening impacts coming, but many of them have been surprised by the ferocity with which some have played out. On this week’s episode of Zero, Bloomberg Green’s Akshat Rathi speaks with his colleague Eric Roston, and Texas Tech University professor Katharine Hayhoe explains why we’re all experiencing “...
