Is the EV Transition Stuck in Neutral?
In 2024, BloombergNEF predicted electric vehicles would make up nearly half of U.S. new car sales by 2030. Now, they’ve revised their projection down to less than 30%, just one year later.
In a time when we need to be speeding up the energy transition, EV sales in the U.S. are stagnating. Sales of Teslas, once the king of electric vehicles, are collapsing. What’s behind the slowing demand? And with China’s growing electric car industry growing, how much should we worry?

Matthew LaBrot, Former Tesla sales employee
Mike Murphy, CEO, EV Politics Project

Dead Heat: The Danger Of Home Power Shutoffs
Summer is here, temperatures are rising — and so are electric bills. That also means many people are facing a severely overlooked issue: power shutoffs. In 2024, over 600,000 households in the United States had their power shut off due to an inability to pay. When that happens, people cannot turn on their lights, keep food refrigerated, or cool down the home. And regulations preventing shutoffs during extreme heat events are woefully inadequate.
But when utilities help pay the upfront costs of efficiency upgrades, the customers and utilities can both save energy — and money. How do we protect the most vulnerable populations from the dangers of home power shutoffs?

Super Pollutants: The Hidden Half of Global Warming
Carbon dioxide is a big deal. It’s responsible for about half of global heating. But what about the other half? There’s actually good news here: Nearly half of the temperature increases driving climate disasters come from super pollutants, most of which don’t stay in the atmosphere for nearly as long as carbon dioxide — which can last for centuries. Methane, for example, is about 80 times more potent at warming the climate than carbon dioxide over 20 years. But it only stays in the atmosphere for a fraction of the time. So if we can put the brakes on methane and other super pollutants, we can put the brakes on warming.

I’m Walkin’ Here! A Report Card on Congestion Pricing
In January, congestion pricing went into effect in New York City. The policy’s implementation took decades; along the way, multiple moments suggested that it wouldn’t happen at all. Now, drivers entering Manhattan south of 60th Street during peak hours are required to pay a toll. Meanwhile, other cities like San Francisco are considering a similar initiative. But Trump opposes New York’s plan. Governor Hochul and state policy leaders encountered a political quagmire pushing the plan through. And its future is only certain up until around next fall, when legal proceedings are expected to come to a resolution.
So, is congestion pricing making a worthwhile difference? How do New Yorkers — and those traveling into Manhattan — feel about it?

Honoring Environmental Heroes in 2025
Would you stand up against a giant corporation to stop toxic chemicals from harming your town’s water? Could you get policy enacted to cut emissions affecting people living in your state’s “diesel death zone?” How would you launch a global campaign to stop the construction of a new port threatening marine life on your island?
Every year, the Goldman Environmental Prize is awarded to six grassroots environmental heroes from around the world at a grand ceremony at the San Francisco Opera House. This year, Climate One was honored to host two of the winners for an intimate conversation. In this episode we also share a conversation with a winner of last year’s Prize. All three are remarkable examples of ordinary people taking extraordinary action to protect the environment and their communities.

San José Mayor Matt Mahan: Live from SF Climate Week
Climate progress is stalling at the federal level, making local action more critical than ever. “In an increasingly urbanized world, cities must play the leading role in achieving our climate goals,” says San José Mayor Matt Mahan.
But what does that look like in practice? What role can cities play in accelerating the transition to a fully electrified economy across all sectors? And how does he plan to secure funding in uncertain times?
This conversation was recorded live as part of SF Climate Week 2025.
