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.

Congressman Jared Huffman: Live from SF Climate Week
Rep. Jared Huffman has represented California’s 2nd District — from the Golden Gate Bridge to the Oregon border — for over a decade. During that time, he has championed climate issues and fought to protect California’s public lands, prevent offshore drilling, pushed for financial institutions to divest from fossil fuels, and introduced legislation to tackle plastic pollution.
Now, turmoil in the federal government is putting all those protections at risk. Advocating for climate action is pretty challenging when terms like "climate change” are being erased from government websites. How can Rep. Huffman advance his climate agenda when those who hold the most power are going hard in another direction?
This conversation was recorded live as part of SF Climate Week 2025.
Guest:
Rep. Jared Huffman, U.S. Representative (D-CA 2nd District) and Ranking Member of the House Natural Resources Committee
