Last time around they were bulwarks for climate action. This time is different.

This story is part of a Heatmap series on the “green freeze” under Trump.
Following Donald Trump’s election in November, climate advocates self-soothed with the conviction that cities and states would continue carrying the banner in the absence of federal climate action. That’s what happened during Trump’s first presidency, after all. When he pulled the U.S. out of the Paris Agreement in 2017, hundreds of local governments declared they were “still in” on climate, and a new wave of state and local climate policies swept the country.
By the time Biden stepped into the White House four years later, many of these communities had climate plans either in place or in progress. When his administration passed the Infrastructure Investment and Jobs Act and the Inflation Reduction Act, setting aside billions of dollars for emissions reduction and climate adaptation projects, they were in a prime position to apply for funding. By November 2024, with most of that money doled out, it was easy to imagine how climate-forward cities could forge ahead, seeded by grants, regardless of what Trump did.
Except then Trump did the thing that many assumed he would not — because he legally could not — do. He froze and is now trying to claw back congressionally appropriated, contractually obligated funds. And in so doing, he has thrown the prospects for cities as a last line of defense into question.
“In this administration, it’s a lot more chaotic,” Barbara Buffaloe, the mayor of Columbia, Missouri, told me. “There’s a lot more happening than I feel like there was in 2017, right at the get-go. Nobody knows what the universe is right now.”
Columbia was among those that joined the “still in” campaign in 2017. It adopted emissions reduction goals in 2018, and passed a climate action and adaptation plan in 2019. The Biden administration awarded the city more than $28 million across three separate federal grants to build electric vehicle charging stations, make electrical upgrades that would allow it to charge electric buses, and redesign its central business loop to be more walkable, bikeable, and safe.
All three of those grants are now up in the air. Buffaloe said she was told by state partners that the $2.1 million business loop planning grant from the Department of Transportation’s Reconnecting Communities program was paused. Columbia was the only city in Missouri to get a Charging and Fueling Infrastructure Grant from the DOT, with the $3.6 million supposed to help pay for EV chargers at the library and the airport. The city is moving ahead with initial activities like environmental reviews and preliminary engineering in the hope that funds to build the actual stations will be unfrozen by the time it’s ready to break ground. Regarding the $23 million bus infrastructure grant, part of a separate DOT program, she said the city hasn’t heard from its grant managers in about a month.
“We don’t know whether or not to continue on the projects,” she told me. “It’s that feeling of uncertainty and trepidation that is causing us the most anxiety. Our construction window is not year-round in Columbia, and because we’re a public institution, it takes a lot longer for us to put out bids and to start projects. We need to know if we have this budget or not.”
It’s not just the funding freeze leaving Columbia in a holding pattern. The city has a municipally-owned electric utility that had been looking to take advantage of “direct pay,” an option for nonprofit entities with no tax liability to collect federal renewable energy incentives as direct subsidies, to help it build more solar farms. But now Republicans in Congress are considering eliminating direct pay.
The funding freeze has put a lot of cities in this position where time-sensitive decisions are stalled. Hundreds of communities were awarded grants from the U.S. Department of Agriculture program to fund tree-planting for carbon mitigation and shade creation, for example. Some recipients have been told their grants were canceled altogether, others are still in the dark — their federal grant managers have been fired and no one is responding to their emails.
“They’re kind of at this point of, hey, do we put in the order for trees? We need to plant at certain times of the year,” Laura Jay, the deputy director of Climate Mayors, a national network of mayors working to address climate change, told me. “For a lot of these cities and programs, there’s key decisions that they have to be making, and when there’s uncertainty around it, it puts the city at a huge risk.” There’s financial risk, she said, in terms of spending money without knowing if it will get reimbursed, but also planning risks. A number of cities were awarded grants to purchase electric school buses, for example, and they need to make sure they are going to have enough to get kids to school.
As a larger, wealthier city, Columbia is in a better position than others. It collects revenue through a capital improvement tax that Buffaloe said could be used for climate projects. “We’ll do as much as we can,” she told me.
But in more rural areas, these grants represented a rare opportunity to modernize and build more equitable access to infrastructure.
“We’re in Southeast Ohio, which traditionally has been left behind when it comes to larger infrastructure projects,” Andrew Chiki, the deputy service-safety director in Athens, Ohio, told me. “We don’t have an interstate highway.”
Chiki helped lead a regional effort to apply for a Charging and Fueling Infrastructure Grant, the same program Columbia won funding from that is now frozen. He and his partners were awarded $12.5 million to build a corridor of electric vehicle chargers in 16 communities between Athens and Dayton. “One of our attempts with this was to answer the question, if EV adoption takes off the way that we are envisioning, how do we allow an on-ramp for communities that are already disadvantaged to be able to adopt?”
Chiki said they were still waiting to hear whether they could move forward with the project or not. Athens passed a resolution declaring a climate emergency in 2020, and adopted a target to reduce emissions by 50% over 10 years. The city has made some strides, Chiki said, by making buildings more energy efficient and installing solar on city-owned facilities. “We are still committed to doing as much as we can,” he told me.
But if the EV charging grant falls through, the smaller villages and towns between Athens and Dayton that don’t have the staff resources or capacity to apply for these types of grants will lose out, he said. “We would probably look at other types of funding sources, but it would make it incredibly difficult and not be nearly as broad as we want.”
There are some pots of money for local climate projects that have flown under the Trump administration’s radar. Last year, the South Florida ClimateReady Tech Hub, a consortium of local governments, schools, labor groups, and companies working to accelerate the development of climate technologies, won a $19.5 million grant from the Department of Commerce’s Economic Development Administration. The money came from the Biden-era CHIPS and Science Act, a law that Trump is pushing Congress to scrap but that Republicans have thus far defended. Tech Hub will use the funds to scale low-emissions cement that can be used for adaptation projects, energy efficiency, and workforce development, among other things.
Francesca Covey, the chief innovation and economic development officer for Miami-Dade County and regional innovation officer for the Tech Hub, told me the group has continued to have quarterly check-ins with federal partners and haven’t gotten any signal that the funding is in jeopardy. “It’s really been more business as usual,” she said. Covey also mentioned two pilot projects to build artificial reefs and seawalls in the area that had funding from the Department of Defense and were moving forward.
Still, the Tech Hub has adjusted its language to stay competitive in the new political environment. The group changed its name to the Risk and Resilience Tech Hub two weeks ago, Covey told me. “We wanted to underscore the economic imperative of the work,” she said, when I asked what motivated the name change. “Right now we’re finding that where we are getting the best traction with the private and public community is around risk. We wanted to make sure we were couching it in the right way.”
Ithaca, New York, on the other hand, which passed its own Green New Deal in 2019, is committed to its climate and equity-centric messaging. “We are not intending to change the narrative around what we’re doing,” Rebecca Evans, the city’s sustainability director, told me. “It’s still clean energy, and it is still because climate change is a threat to human existence. We are still going to prioritize black and brown populations and populations that experience poverty at various levels because they are most vulnerable to climate change.”
About 85% of Evans’ Green New Deal budget comes from federal sources, and at first she worried that was all at risk. In 2022 and 2023, Ithaca had received funding from what’s called “congressional directed spending,” or “earmarks,” in two federal appropriations bills, meaning that New York state lawmakers fought to get money set aside for the city. The first grant, worth $1 million, was for a hydrogen production and fueling project. The second, worth $1.5 million, was for a wide-ranging program to decarbonize the school system and enhance a local workforce development program to include new energy efficiency certifications. Both programs included explicit diversity, equity, and inclusion-related objectives, so Evans assumed they would be targeted by the Trump administration.
But on Tuesday, she was told by federal partners on the hydrogen grant that congressionally directed spending was not subject to Trump’s executive orders and got the greenlight to move into the next phase. Evans still hasn’t heard back from her federal partners on the second grant, but she’s more hopeful now that it will move forward.
Back when I first spoke to Evans, when things were more up in the air, she told me she worried that the Trump administration’s actions would cause advocates to lose hope. “I think anger can be a positive thing, but it’s the loss of hope, even if it’s marginal, that is truly, truly dangerous to this movement.”
Perhaps that’s why Evans, like all of the other local leaders I spoke with, projected optimism when I asked what they could accomplish over the next four years without federal support. She was already trying to find the money elsewhere, she said. “We can’t do all of the amazing things that we wanted to do, but we can still make progress,” she said.
“Cities are incredibly nimble and innovative,” Jay, of Climate Mayors, told me. “I think that they’re eager to and committed to keeping the work going. What that looks like, I think, is hard to figure out right now, because everyone’s kind of caught in the chaos of trying to figure out if they still have this funding or not. But they’re fully committed to making sure that this work is continuing.”

‘Our entire company was built for this purpose.’
After decades of stagnation, the nuclear industry has drummed up all kinds of ideas meant to revive the prospects for building reactors in the United States. Make the reactors smaller. Micro, even! Cool them with helium or molten salt instead of water. Invite the Koreans or Canadians to come teach us how to construct atomic power stations again.
Yet the startup bold enough to name itself The Nuclear Company launched in 2024 on a simpler thesis: Just go with the large-scale reactors we have built before, and construct them in bulk to bring down costs.
Essentially, do what the Chinese did.
While the U.S. struggled for 15 years to complete its first two Westinghouse AP1000s, the 1.1-gigawatt units designed at the dawn of this century to be America’s flagship nuclear technology, China built four in the same time period. Beijing then reverse-engineered the technology to make its own version with an entirely domestic supply chain. China now has 10 operating Hualong One reactors and at least 37 more on the way. The U.S. ultimately completed its first two AP1000s at Southern Company’s Alvin W. Vogtle Electric Generating Plant in eastern Georgia right around the same time.
The Nuclear Company was formed by hiring former managers who oversaw the Georgia project. Despite the Trump administration’s pledge to finance construction of at least 10 more large nuclear reactors, the only projects that have broken ground are new, first-of-a-kind small modular reactors that skeptics fear will face the same billion-dollar cost overruns that the AP1000s faced at Plant Vogtle — but without the same output of electricity to balance out the expenses.
On Wednesday morning, The Nuclear Company announced its most significant attempt at a Chinese-scale buildout yet. The firm unveiled plans to build 6.6 gigawatts of new, large-scale reactors at a greenfield site in Kentucky, along the Ohio River. Dubbed Prosperity One, the project would be located in Lewis County, on property once assembled for a coal-fired station that was later abandoned. The site sits half a mile from a 765-kilovolt transmission line that connects to PJM Interconnection, the nation’s second-largest and arguably most stressed grid system.
“Our entire company was built for this purpose,” Joe Klecha, The Nuclear Company’s chief nuclear officer and a former manager on the Plant Vogtle buildout, told me. “We recognize that this is different and unique in our country. We believe it’s very much needed.”
The project will begin with two reactors at a time; the Kentucky site has room for up to six. The Nuclear Company is already negotiating potential offtake agreements with electricity buyers to help finance construction, and it expects deals by next year. The company told me it has not yet decided whether it will run the Prosperity One as an independent power provider or sell the facility to a utility or another plant operator. “We are preserving all options and will make that decision as we pull the other partners onboard formally,” Klecha said.
Since its inception, The Nuclear Company has focused on the AP1000 as the most promising design in the U.S. That’s particularly true after the Nuclear Regulatory Commission certified the Vogtle Unit 4 design last week as the permanent, settled schematic for future AP1000s.
But Klecha left open the possibility of another technology. “The AP1000 is our basis for the site at this point, but we’ll continue to evaluate other options as we get through the site characterization,” he said. He expects that process to wrap up in “the first half of next year.”
The company’s options are limited, though. Last month, as I reported, South Korea agreed to help the U.S. build up to six new AP1000s at an as-yet-unspecified site in addition to constructing at least two APR1400s — that is, essentially the Korean version of the American technology. In theory, The Nuclear Company could build APR1400s, too. But it’s highly unlikely, since Westinghouse accused the state-owned Korea Electric Power Corporation of ripping off its technology for the APR1400 in 2022. That led to a yearslong lawsuit and settlement that gave the American company the right to demand royalties and keep Seoul out of markets where Westinghouse aims to compete.
The only other viable option is the ABWR. The world’s first so-called advanced reactor, the ABWR was built with General Electric’s boiling water reactor technology, which is used across about a third of the U.S. fleet. It serves as the second-most popular design after Westinghouse’s pressurized water reactor model. Japan successfully built four ABWRs over a decade from 1996 to 2006, and Taiwan nearly completed two before killing the project in a bid to phase out nuclear power altogether. The NRC certified the ABWR for construction in the U.S., but a project in southern Texas that aimed to build the first in the U.S. was scrapped about a decade ago.
“The ABWR has an impressive pedigree of construction success as well as experience being built to U.S. standards that is hard to find outside of the Vogtle project,” Brett Rampal, a veteran nuclear consultant who advises Deloitte and Veriten, told me. Still, he said, the AP1000 is the leading contender for the Kentucky site.
Rampal said Prosperity One represents a welcome break from how large-scale reactors have been planned in recent years. While most of the industry remains focused on small modular reactors, research I covered last month indicates the technologies could face worse cost problems than large-scale units, and the emerging consensus on building AP1000s focuses on expanding existing nuclear plants.
Indeed, The Nuclear Company’s first major deal was to help Brookfield Asset Management, which owns 51% of Westinghouse, complete a thwarted AP1000 project at the V.C. Summer plant in South Carolina. But other potential sites considered for new AP1000s included expansions of Florida Power & Light’s Turkey Point nuclear plant in Florida, the Tennessee Valley Authority’s Bellefonte nuclear station in Alabama, or even adding another two units to Plant Vogtle.
“A lot of the thoughts around AP1000s and large reactors have always been around existing or already-licensed sites,” Rampal said. “It’s very interesting to see TNC’s first project buck the trend of what folks have been talking about around the large reactor story in this country."
At least one thing is certain about The Nuclear Company’s approach: It will settle on one design. The company is animated by the need to avoid one of the U.S. nuclear industry’s biggest financial mistakes, known simply and derisively as “Whoops.” In 1983, the Washington Public Power Supply System — WPPSS — triggered what was then the largest municipal bond default in U.S. history after its buildout of several different reactor designs at once fell apart in a major boondoggle.
Building different reactors at Prosperity One “really goes against our mission, our vision, and our thesis as a company,” Klecha confirmed.
The key is repeating the same design over and over again so the project managers sort out the fastest, most efficient ways to build and workers hone skills in actually constructing the design. “Six AP1000 units on one site creates the scale and repetition needed to drive down costs and sends a strong signal to the supply chain,” Lin Yuan, the senior advisor at the Nuclear Scaling Initiative, a non-profit collaboration working to create the enabling commercial and policy conditions for safe and secure nuclear energy scaling, told me in an email. “Manufacturers and craft labor need to see a sustained order pipeline to invest in capacity, factory expansion, and training.”
Vogtle Unit 4 came online in 2024 roughly 30% cheaper and faster than Vogtle Unit 3, completed a year earlier. Klecha said that’s the minimum cost reduction The Nuclear Company expects for the first two reactors built at Prosperity One.
“The 30%, I would say, is the floor on the savings from the first unit to the second unit,” he said. “How do we capture those lessons? Obviously, our team’s experience. We have a pretty rigorous ‘lessons learned’ document.”
Soon, he hopes, there will be even more lessons learned — in concrete, rather than on paper.
