Delaying congestion pricing is one of the worst climate policy decisions made by any Democrat in recent memory.

If it holds, then Governor Kathy Hochul’s decision today to delay congestion pricing indefinitely in New York will be a generational setback for climate policy in the United States.
It is one of the worst climate policy decisions made by a Democrat at any level of government in recent memory.
It is worse than the Mountain Valley pipeline, the 300-mile gas pipeline that Senator Joe Manchin of West Virginia got approved in 2022 in exchange for supporting the Inflation Reduction Act.
And it is worse than the Willow project in Alaska, the oil mega-project that President Joe Biden okayed last year under pressure from that state’s local and indigenous leaders.
It is so bad because it will set back the development of climate-friendly cities and rapid transit infrastructure in the United States for years if not decades. And it will deter other American cities from implementing the kind of time-saving, pollution-averting, anti-gridlock measure that the country desperately needs.
There is nothing good to be said for this decision. It is bad politics, bad economics, bad governance, and bad for the climate.
Let us briefly count the ways that it is destructive.
It is stupid coalition politics. Hochul has alienated her allies, including environmental groups, state budget hawks, and transit advocates. Bill McKibben, the longtime New Yorker writer who has become one of the country’s most famous climate activists, called Hochul’s decision “one of the most aggressive anti-environmental actions ever undertaken by a Democratic governor.”
In exchange, Hochul has delighted her Republican adversaries, who can praise her wise decision-making in the weeks to come — and therefore brandish their own bipartisan bonafides — but continue to campaign against congestion pricing through November. Congestion pricing is unpopular now, but in her fecklessness, Hochul has guaranteed that it will be a live issue in November.
It is nonsense budget politics. Hochul says that she has delayed congestion pricing because she is worried about the city’s recovery from the pandemic, but regardless of her reasons, she has now left a $1 billion hole in the transit authority’s budget. The New York Times reports that she wants to fill that hole by raising taxes on the state’s businesses.
But that means that she has taken a tax formerly charged to some New York residents and businesses — but which would also fall on New Jersey and Connecticut residents and businesses — and shifted it entirely to in-state entities. She has, in essence, cut taxes on out-of-state residents and raised taxes on New York businesses and consumers.
And instead of taxing the right to use roads in downtown Manhattan, which are a limited public resource, she will instead tax all business activity in the state. What good will that do for New York’s economy?
Those political and financial flaws might be forgiven if her decision was good for the planet. But don’t worry: It’s also bad climate politics.
Cars, SUVs, and trucks belch more climate pollution into the atmosphere than any other single economic activity in the U.S. Nearly 20% of America’s annual carbon pollution comes from individuals and families driving their private vehicles around on roads and highways. This is a far larger share of national pollution than is generated by more famous climate villains, such as air travel.
We have good ways of dealing with all that carbon pollution. In suburbs, small towns, and rural America, the best way to deal with that tailpipe pollution is to gradually transition from gasoline-burning cars to electric vehicles. In some places, the country can also experiment with using experimental, climate-friendly liquid fuels.
But in cities, people have better and cheaper options than getting EVs. We can stop requiring people to drive everywhere and encourage them to walk, bike, and take public transit instead. That will require, at times, treating the use of roads in city centers as the limited public resource that it is — which means charging cars and trucks to enter the most crowded downtown areas of certain cities at certain times of the day.
That’s what congestion pricing is: a way of encouraging cities to grow in pro-climate, pro-environmental ways. Such a policy has already been successfully implemented in London, Singapore, and other congested cities. Even as an urban car owner, I long wanted the city where I lived for a decade — Washington, D.C. — to adopt a similar policy. After all, when Stockholm started its congestion fee, the rate of asthma attacks among its children dropped by half.
So I looked forward to the start of congestion pricing in New York City, America’s biggest, densest, and most transit-friendly city. New York was bushwhacking a trail for everyone else to follow: If congestion policy was a success there, then other American cities could experiment with it in some form.
By pausing that trial before it has even begun, Hochul has essentially frozen our ability to experiment with congestion pricing anywhere else in the country. By shuttering the policy in New York, she has poisoned pro-climate urban politics everywhere. Now people will say: You saw what happened when New York tried to do congestion pricing. Do you really want to try that here?
In the past, when national Democrats have approved new pipelines or oil projects, they have argued that those projects will not affect the country’s carbon pollution because only demand for fossil fuels, and not the supply of them, drives carbon emissions. But what makes congestion pricing so powerful is that demand is precisely what it targets. Congestion pricing makes buses run faster, pays for the subway system, and pushes people and businesses to consider the social cost of their driving before they get in the car.
Congestion pricing, if implemented widely, can actually conserve fossil fuels and cut carbon emissions. Now Hochul has halted its progress everywhere.
She has made, in other words, a local mistake with national and even global consequences. It is such a foolhardy error that it instantly recasts Kathy Hochul’s climate record as governor.
Hochul has previously been seen as a center-left governor playing a difficult but moderate environmental hand. But is that really her record? She has struggled to build wind farms off the coast of New York, even though it is essential to decarbonizing the state’s power grid. She has so far failed to pass the NY HEAT Act, which would help the state transition away from using fossil fuels to heat its buildings. She has even failed to pass little climate measures that would fund the state’s more modest climate goals.
I would compare her to Senator Joe Manchin, the fossil-fuel-friendly West Virginia lawmaker who repeatedly refused to vote for Biden’s climate policy — except at least Manchin put his political reputation on the line when it mattered and ultimately negotiated, and voted for, the Inflation Reduction Act. At least Manchin has many qualities to recommend him: He was canny, risk-taking, proud, and courageous when it counted. Hochul is just a loser.

Current conditions: The fast-moving Palos Fire blazed through 17 acres in Los Angeles’ La Habra Heights, injuring two • Heavy rain in São Paulo collapsed a dilapidated building, killing six • The heat index in the Mississippi Valley is topping 110 degrees Fahrenheit.
Two weeks after accusing data center opponents of wanting “to end up being backwards and poor,” President Donald Trump has landed on a new defense of the artificial intelligence buildout. It’s a lot like his old one for abdicating on the federal government’s responsibility to deal with climate-changing emissions. Essentially, it boils down to: My critics are making it all up. “It’s a hoax,” Trump told Nvidia CEO Jensen Huang during the five-minute call the executive put on speaker on stage at a conference Monday in Los Angeles. “The robots are not going to be taking over the world. That’s not going to happen.” He later posted on his Truth Social platform: “The AI Hoax being perpetrated by the Radical Left Dumocrats is reminiscent of their Global Warming Scam of not so long ago, where everyone was going to die from extreme heat. What happened? MAKE AMERICA GREAT AGAIN!!!” Three-quarters of Americans are now opposed to data centers in their backyards, according to Heatmap Pro’s poll from last month. But Trump has recently bucked with some populist positions on technology that have cross-partisan appeal. While law-and-order Republicans in red states are now turning against the Flock cameras that watch for petty crime, Trump defended the technology in a recent Air Force One chat with reporters. “Trump deserves more respect for his anti-slopulist instincts,” Peter Meijer, a former Republican member of Congress who voted to impeach Trump during his previous administration, wrote in a post on X.
Nvidia’s emissions, meanwhile, appear to be soaring. A new Greenpeace analysis of Nvidia’s own climate reports by the pro-renewables analyst Ketan Joshi found that emissions relating to the supply chain for chip manufacturing soared by 725% since 2020, adding nearly 10 million metric tons of carbon dioxide to the atmosphere.

You wouldn’t believe some of the conditions I have heard placed on owners of hydroelectric dams seeking to relicense major clean power projects. There are obvious demands from regulators for things like new infrastructure to help migrating fish pass down a river. Then there are the less obvious, such as building an amphitheater for Boy Scouts or paving new roads far from a dam or its water source. In what the trade group called a first-of-its-kind analysis, the National Hydropower Association reviewed more than 5,000 mandatory conditions across 4,819 licensing documents filed between 1980 and 2026 in 46 states. Dam owners would need to agree to the legally binding requirements, imposed by either state or federal agencies, before a final operating license could be issued. Compared to earlier licenses, hydropower plants today “carry roughly 10 times as many mandatory conditions,” the trade association wrote in its report. “To make matters worse, many conditions are unrelated to energy production and are essentially ‘wish list’ items that hydropower producers are asked to fund, ranging from road construction unrelated to the projects to building fish passage far beyond where the fish actually are (or even could be),” the organization said. Over the next decade, 348 hydropower permits representing 12 gigawatts of capacity are due for relicensing. Many of those facilities are small, and the trend recently has been for companies to simply surrender their licenses and close up shop rather than make costly renovations.
“I urge anyone who cares about reliable, affordable power to read this groundbreaking study,” Malcolm Woolf, NHA’s top executive, said in a statement. “Hydropower, a superhero of the grid and an American icon of energy production, is at great risk due to a broken regulatory framework. Relicensing an existing hydropower facility often takes decades and costs millions of dollars. If these facilities go away, so does the affordable power they produce, the good jobs they create, and the critical infrastructure and ecosystem care they provide.”
Back in May, I told you that South Korea — arguably the most competent builder of atomic power reactors in the democratic world — was “coming to America’s nuclear rescue.” Last week, we discussed the possibility of Seoul’s state-owned nuclear company building reactors in the U.S. as part of a trade pact with the Trump administration. Now we have a clearer picture of where those negotiations may be going. On Tuesday, The Korea Economic Daily reported that South Korea is seeking a roughly 15% stake in Westinghouse, the maker of America’s flagship nuclear reactor, and a seat on its board as part of any deal with Washington. The move, the newspaper noted, is designed to “turn a U.S. request for Korean capital into a strategic foothold in America’s nuclear buildouts.” Ownership by one of America’s closest East Asian allies would be nothing new for Westinghouse, which was owned in the mid 2000s by the Japanese industrial giant Toshiba. Today Westinghouse is a privately held joint venture between the publicly traded investment behemoth Brookfield Asset Management and the Canadian uranium miner Cameco, but the company filed confidential paperwork to the Securities and Exchange Commission in July as a first step toward going public on the stock market.
The market only appears to be expanding. Global nuclear capacity could more than triple by 2060, according to this week’s latest forecast from the International Atomic Energy Agency, the United Nations affiliate that oversees nuclear technologies worldwide.

Spend a few minutes scrolling through a comedy fan’s TikTok stream and you’ll find skits playing to the same memetic trope, an anthropomorphized caricature of an incompetent, mistake-prone AI agent guzzling and spilling lots of water. It’s no wonder the joke has already become hack. More than three-quarters of Americans are at least somewhat concerned about the environmental impact of AI, and half are extremely or very concerned, according to data from the latest annual poll from the University of Chicago’s Energy Policy Institute and the AP-NORC Center for Public Affairs Research. In every case, self-identified Democrats are more concerned about environmental issues than Republicans. While 40% of Democrats expressed concern over the environmental impacts of cryptocurrency, just 18% of Republicans said the same. With meat, the ration is 42% to 21%. With air travel, it's Democrats at 38% and Republicans at 17%. But interests converge slightly more on data centers, with 65% of Democrats and 42% Republicans extremely or very concerned about the environmental impacts of AI.
In theory, the late 20th century liberalization of America’s electricity markets should have put a premium on transmission companies building new arteries in the system. In practice, the high cost and grave risk of taking on dozens, sometimes droves, of landowners for right of way to build a power line that stretches hundreds of miles across multiple regional grids makes the task almost impossible, particularly in markets where a power company can’t offset the cost of new lines with other sources of revenue such as generation or power sales. A new report by the Center for Public Enterprise has concluded that “only the federal government can intervene to sew together this national macrogrid by bridging the jurisdictional divides between utilities and regions, instituting planning pipelines with access to finance and cost recovery, and fixing interconnection procedures.” As of yet, that looks unlikely beyond the increased focus on regional planning under the Federal Energy Regulatory Commission’s Order 1920. The rule is facing legal challenges that aren’t expected to be resolved until next year, according to Ari Peskoe, director of Harvard Law School’s Electricity Law Initiative.
When I visited Commonwealth Fusion Systems’ headquarters in Massachusetts earlier this summer, I saw how much progress the company had made toward building what could be the world’s first power-producing fusion reactor, called SPARC. To work, the interior of the torus-shaped, doughnut-like reactor needs to be very cold so magnets can pick up on the contrast in temperatures with the extremely hot plasma fusing together. That’s where the cryogenics come in. The facility’s cryogenics equipment is now up and running, the company said on Wednesday, marking yet another milestone toward next year’s anticipated start up. “That temperature, a few degrees above absolute zero, is what’ll enable our magnets to bottle up a superhot cloud of charged particles called a plasma so fusion can occur,” Adam Weiner, the director of cryogenics at Commonwealth Fusion Systems, said in a statement.
Rob talks with climate and data expert Hannah Ritchie about her new platform, U.S. Energy Data.
America has some of the world’s best data about its own internal energy, industrial economy, and carbon emissions. That’s thanks to a federal agency called the U.S. Energy Information Administration, which painstakingly collects and updates the data every week.
But EIA data can be hard to access — and even harder to share and understand. A new project aims to change that. U.S. Energy Data takes federal energy data and repackages it, helping amateurs and experts understand the power grid, liquid fuels, and more. It is now the easiest way to make and share charts with federal energy data.
On this episode of Shift Key, Rob is joined by Hannah Ritchie, a data scientist and writer who advised and prototyped US Energy Data. She is also the author of Not the End of the World and Clearing the Air, as well as a senior researcher at the University of Oxford and the deputy editor at Our World in Data. Rob and Hannah discuss how the platform came together, what makes it such a valuable resource, and what we can learn from it about the state of the energy transition.

Here is an excerpt from their conversation:
Robinson Meyer: One thing that I so appreciate about your work, incluidng two books about climate change and Our World in Data, is that it is grounded, as it says in the title, in data. And that means that unlike those of us who are maybe in the news cycle every day and following the vagaries of policy moving one way and then moving the other way, having a framework through which to understand the world, I think a data-driven framework especially, means that you can update more slowly. And at least when you update your worldview, it’s grounded in a change which is surprising you or important, or that’s standing out, you know, in the real world, and not just in the kind of discursive or political world that we tend to cover.
At the risk of asking a very large question, how are you feeling about global decarbonization at the moment? As someone who works in the data, who looks at the data, what do you think hasn’t been noticed at the moment? I have a candidate here, but I’m curious what you think as well.
Hannah Ritchie: I think that in terms of global decarbonization, I’m still pretty optimistic. And I think one of the key distinctions there, I think when it comes to these discussions, we do naturally focus on the U.S.. And I think decarbonization in the U.S. has gone slowly, and too slowly, and has faced setbacks. And I think there is the temptation to extrapolate that view and say, well, the world is not doing well on decarbonization. And I don’t think that’s correct. I think, to not be too much of a centrist on this, we’re not going as fast as I would like, or what we frame as what we should need to be. But I do actually think that things are moving pretty quickly and accelerating in other parts of the world.
And I think the challenge there is, I think people are not saying that, yes, China is moving very quickly on this. But a key point there is, if you look at other countries, low- and middle-income countries across Latin America or Sub-Saharan Africa or Asia, many of those countries are also moving fast. And I think that’s underappreciated. And I think they’re moving fast because the energy transition and electrification and decarbonization just increasingly makes economic sense to do so.
So I guess the trade-off between increasing energy services for people — for which, in many low- and middle-income countries, that’s just a core part of development. And a key priority is no longer incompatible with also doing that in a relatively low-carbon way, and I think that’s a really key, underappreciated point, and you start to see that in these annual updates of what happened in the last year, and I think you miss it if you’re only looking at, you know, the headline from yesterday and the headline from today.

Google, Nvidia, and Emerald AI are founding members.
Nvidia, Google, and data center software startup Emerald AI are teaming up to lead the AI Energy Management Alliance, a trade group dedicated to promoting flexible load for AI data centers, the organizations announced on Wednesday.
“There are a lot of AI trade associations, data center trade associations, energy trade associations. This is the only one that is laser focused on flexible AI data centers,” Varun Sivaram, founder and chief executive of Emerald AI, told reporters in a briefing earlier in the week.
The group represents the evolution of an older trade association, the Advanced Energy Management Alliance, which was founded in 2014 and advocated for demand response for large electricity customers. Energy policy veteran Frank Lacey will lead the reconstituted group, which will also include other energy and AI heavyweights among its members, such as Anthropic, NRG, and Constellation Energy.
The pursuit of policies and technologies that can enable data centers to reduce their draw on the grid during moments of peak demand has been something of a holy grail for energy policy practitioners and hyperscalers like Google. That’s because much of the cost of building out and maintaining the grid — including greenhouse gas emitting gas-fired powered plants — is for meeting those peak hours.
“The savings to consumers if we had effective flexibility is enormous,” Abraham Silverman, former general counsel at the New Jersey Board of Public Utilities and assistant research scholar with the Ralph O’Connor Sustainable Energy Institute at Johns Hopkins University, told me. (He is not involved with the alliance.) “It’s when you get up to the hottest or coldest day of the year that you need that extra transmission line or need to build a new one,” which then drives up costs for everyone, Silverman said.
A recent Johns Hopkins analysis of the grid operator PJM Interconnection, which covers large portions of the Mid-Atlantic and Midwest, found that “requiring data centers to accept occasional power interruptions saves over $15 billion per year.”
State and local regulators have shown openness to a variety of approaches that could get data centers on the grid faster while minimizing impact on the grid. “Just about every state has some either legislative or regulatory process for looking at this,” Silverman said.
The case for flexibility picked up steam last year thanks to an academic paper co-authored by energy systems expert Tyler Norris, who at the time was a researcher at Duke University’s Nicholas School of the Environment and is now Google’s head of energy market innovation. Norris argued that much of AI data center electricity demand could be served by the existing grid with modest flexibility.
“The limiting factor for new digital infrastructure isn't capital or silicon; it's power,” Norris told the reporters during the briefing. “But the biggest near-term barrier isn't a lack of electricity. Multiple studies have found that if new loads are able to reduce their draw from the grid for a small fraction of the year — less than 100 hours during peak periods — we can add dozens of gigawatts of new load to the existing U.S. power system.”
Google says it has 1 gigawatt of demand flexibility integrated into its existing utility contracts, while Emerald, which recently fetched a valuation of just over $1 billion, is working on a 100-megawatt data center with Digital Realty and Nvidia in Virginia. That facility “is intended to demonstrate a model that future AI factories around the world can adopt,” Josh Parker, the head of sustainability at Nvidia, told reporters on the call.
“What we want to do is to better utilize that infrastructure,” Parker added. “Every watt wasted is a watt that could have been used to generate tokens, which could lead to life-saving treatments, or economic productivity, or even energy efficiency in other sectors that dramatically improve our sustainability outcomes.”
The effort is especially noteworthy because it explicitly seeks to make building data centers easier amidst mounting and diffuse skepticism from the communities that may host them and the public as a whole. Part of the case for flexible load is to solve for the mounting utility bills widely predicted to accompany AI’s expansion.
“The real goal,” Sivaram said, is “more community-friendly and grid-friendly data centers — data centers that are good grid citizens all across the country.”
Concern over the energy system’s ability to meet the demand from AI has reached the federal level. In June, the Federal Energy Regulatory Commission asked the six large independent power markets to come up with reforms to help protect the grid and consumers from the huge predicted rise in demand from data centers. Those include coming up with “new transmission services to reflect large load flexibility,” as FERC Chair Laura Swett put it. A trade group focused on flexibility could push forward these conversations in a coordinated way, ideally bringing together state and federal regulators, Silverman told me.
Right now, any effort to reform data center interconnection tends to ping pong back and forth between states, the federal government, and the regional transmission organizations, with major players trying to have their case heard at whatever level they think will be most favorable to their interests. For example, Microsoft is contesting a Virginia rule over data center cost allocation, claiming it stands to get in the way of federal rules.
“This new trade association could be very helpful in bringing together the companies for whom flexibility is a competitive strength and give them a voice,” Silverman told me.
