The end has been coming for a while. With the EPA’s new power plant emissions rules, though, it’s gotten a lot closer.

There’s no question that coal is on its way out in the U.S. In 2001, coal-fired power plants generated about 50% of U.S. electricity. Last year, they were down to about 15%.
On Thursday, however, the Biden administration arguably delivered a death blow. New carbon emission limits for coal plants establish a clear timeline by which America’s remaining coal generators must either invest in costly carbon capture equipment or close. With many of these plants already struggling to compete with cheaper renewables and natural gas, it’s not likely to be much of a choice. If the rule survives legal challenges, the nation’s coal fleet could be extinct by 2039.
Coal plant retirement presents a two-pronged problem: Utilities have to figure out how to replace lost power generation, and the surrounding community must reckon with the lost tax revenue and jobs from the power plants and the coal mines that supplied them.
From the beginning, Biden has promised to help revitalize the economies of the communities left in coal’s wake. “We’re never going to forget the men and women who dug the coal and built the nation,” he said when he laid out his energy transition plan just a week after entering office. “We’re going to do right by them.”
Economic revitalization doesn’t happen overnight, of course, or even in the span of a four-year term. But money is already rolling out in the form of targeted investments in new energy sources, businesses, and jobs in coal communities, and there’s more to come.
It’s the proactive planning aspect, however, that remains underresourced and scattershot.
Emily Grubert, a civil engineer and sociologist at the University of Notre Dame, told me there are few plants that are expected to make it past 2039 regardless, due to their age and the economics of operating them. The emissions rule’s real potential, then, is to bring about a more orderly — and potentially less painful — exit.
A Heatmap analysis of Energy Information Administration data found that of the nation’s roughly 230 remaining coal plants, 38 are scheduled to fully shut down by 2032. These plants won’t have to make any changes under the new rule. An additional five will shutter by 2039. These will be required to reduce their emissions in the interim, beginning in 2030, by replacing some of the coal they burn with natural gas. That leaves about 190 plants with either partial retirement plans or no plans at all that will be forced to make a decision between carbon capture and shutting down.
Grubert told me that many of these plants have, in fact, communicated informal plans to shut down that are not recorded in the federal data. That aside, she called it “amazing” how many have no retirement plans at all.
For surrounding communities, an impending coal transition can look really different in different places, depending on geography and how diverse the local economy is. Still, the first step should be the same everywhere. “What you need to do, really practically, is figure out what that plant is supporting,” Grubert told me. “What needs to be replaced, for whom, and by when?
It’s a lot more concrete than it seems: It’s some specific number of people, it’s some specific amount of tax revenue. It’s much easier to move forward once you actually know what those are.”
How much of that work has been done so far depends, in part, on the state. Some, like Colorado, New Mexico, and Illinois, have established new positions or entirely new offices dedicated to helping communities transition off fossil fuels. But other states, like Wyoming and Ohio, have advanced measures to keep coal plants open as long as possible.
Successful planning also depends on how clearly a retirement date is articulated and stuck to, Jeffrey Jacquet, an associate professor of rural sociology at Ohio State University who leads a multidisciplinary research project on coal communities there, told me. Some communities have been told one date and then been blindsided when a plant has been forced to shut down years earlier for economic reasons. He noted one success story in Shadyside, Ohio, where the local school board was able to negotiate a deal to slowly step down its tax collections over four years after learning the RE Burger coal plant was going to close. “Had they not weaned us off losing that tax revenue, we would have been in terrible shape,” a school board administrator told a student on Jacquet’s project. “Fiscally we’re pretty good on solid ground now, but at one point it was an extremely bleak time.”
The new power plant rule could help address some of these problems by putting the entire country on the same set timeline, forcing plant operators to put retirement dates in writing. There’s still a risk some will fail early, in unforeseen ways, but at least communities will have been put on notice.
Those who go looking for help will find ample resources. When I started looking into all of the programs that exist to bring investment into coal communities, or otherwise help them diversify their economies, I was surprised at how much investment in coal communities had already been set in motion:
This list is far from comprehensive. In fact, there are so many programs, it’s kind of a problem.
“So much of it comes down to the local capacity to take advantage of these opportunities,” Jacquet told me. “A lot of these communities are losing population, they’re facing out-migration. Community leaders are already overworked and overstressed.” (Possible case in point: I reached out to several local groups doing coal transition work in West Virginia and Kentucky for this story, and wasn’t able to get anyone on the phone.)
This isn’t a new problem, per se. The federal government had dozens of programs and pots of money set aside for rural economic development before the Biden administration came into the White House, but they were scattered across different agencies and departments within those agencies, making it difficult for any overworked, overstressed town manager to know where to start.
Jeremy Richardson, a manager of the carbon-free electricity program at the think tank RMI, told me he was involved in a group that pitched policies to the incoming president that would help ease the process. “It shouldn’t be on the community to navigate the entire federal bureaucracy to figure out what they qualify for,” he said.
Biden took the note. In his first climate executive order, he established the Interagency Working Group on Coal and Power Plant Communities and Economic Revitalization, which is building tools to help companies and local governments identify funding opportunities. Its “getting started guide,” which Richardson called a “fantastic piece of work,” walks communities and workers through 10 concrete steps, from identifying needs to developing a transition strategy to finding funding and implementing a project, with curated resources for each step. The group also established four “rapid response” teams to provide more targeted assistance to communities in areas with the highest loss of coal assets.
Jacquet summed up the group’s work as “hand holding,” stressing that it still required people at the local level that were willing and able to take advantage of these services. “I think we’re sort of seeing this phenomenon where the communities that are already best positioned to take advantage of these are going to be the ones that take advantage of it,” he said.
There are other limitations to the broader suite of federal assistance programs. For instance, even if a community is able to attract a big manufacturing project, there may be a several-years gap between the coal plant closing and the new job opportunities and local tax revenue manifesting.
That’s why the coordination efforts in states like Colorado, which was the first to establish an Office of Just Transition in 2019, are so promising. The office has a small staff of six, and a meager budget of $15 million, but is making progress by focusing on highly targeted assistance. In the town of Craig, two nearby coal-fired power plants are scheduled to retire over the next four years and four coal mines will shutter by 2030, taking with them 900 jobs and about 45% of the county’s tax revenue. A new “transition navigator” hired in January will help match the town’s needs with federal and state funding opportunities and serve as a central point of contact for coal workers and their families seeking connection to services.
“I think it’s been really helpful,” said Richardson. “They’ve had long conversations — several years of conversations — with those communities in northwest Colorado that are facing closures soon.” The office was controversial at first. Republicans called it “Orwellian” and unanimously opposed it. But in the years since, some of its staunchest critics have become its biggest champions. “To me that says that they’re doing some good work and they’re making some inroads.”
There’s progress on the energy side, too. RMI is pushing a model called “clean repowering,” enabled by a suite of IRA incentives that offer tax credits and loan guarantees for clean energy projects in fossil fuel communities. The idea is that renewable energy projects can get around the yearslong bottleneck of connecting to the grid by building in close proximity to existing fossil fuel plants. A lot of these plants have “spare” interconnection rights that a solar or wind farm could use to connect a lot sooner.
RMI found 250 gigawatts of spare rights available — which is more than the capacity of the entire existing coal fleet. “If you can build a renewable facility alongside where that fossil plant is, maybe you use the fossil plant a little less because it’s cheaper to generate from the renewables, but you know, you don’t have to close it immediately,” said Richardson.
As Daniel Raimi, a fellow at Resources for the Future, told me, even though the coal transition has been in motion for decades, it’s still early. There hasn’t been enough research. Much of the funding and programs are new. No one really knows yet what’s working, or what could work better.
The only thing that’s clear, he said, is that if these communities are going to develop alternative economic futures, they really need to begin that process now.

Agriculture startups are suddenly some of the hottest bets in climate tech, according to the results of our Insiders Survey.
Innovations in agriculture can seem like the neglected stepchild of the climate tech world. While food and agriculture account for about a quarter of global emissions, there’s not a lot of investment in the space — or splashy breakthroughs to make the industry seem that investible in the first place. In transportation and energy, “there is a Tesla, there is an EnPhase,” Cooper Rinzler, a partner at Breakthrough Energy Ventures, told me. “Whereas in ag tech, tell me when the last IPO that was exciting was?”
That may be changing, however. Multiple participants in Heatmap’s Insiders Survey cited ag tech companies Pivot Bio and Nitricity — both of which are pursuing alternate approaches to conventional ammonia-based fertilizers — as among the most exciting climate tech companies working today.
Studies estimate that fertilizer production and use alone account for roughly 5% of global emissions. That includes emissions from the energy-intensive Haber–Bosch process, which synthesizes ammonia by combining nitrogen from the air with hydrogen at extremely high temperatures, as well as nitrous oxide released from the soil after fertilizer is applied. N2O is about 265 times more potent than carbon dioxide over a 100-year timeframe and accounts for roughly 70% of fertilizer-related emissions, as soil microbes convert excess nitrogen that crops can’t immediately absorb into nitrous oxide.
“If we don’t solve nitrous oxide, it on its own is enough of a radiative force that we can’t meet all of our goals,” Rinzler said, referring to global climate targets at large.
Enter what some consider one of the most promising agricultural innovations, perhaps since the invention of the Haber–Bosch process itself over a century ago — Pivot Bio. This startup, founded 15 years ago, engineers soil microbes to convert about 400 times more atmospheric nitrogen into ammonia than non-engineered microbe strains naturally would. “They are mini Haber–Bosch facilities, for all intents and purposes,” Pivot Bio’s CEO Chris Abbott told me, referring to the engineered microbes themselves.
The startup has now raised over $600 million in total funding and is valued at over $2 billion. And after toiling in the ag tech trenches for a decade and a half, this will be the first full year the company’s biological fertilizers — which are applied to either the soil or seed itself — will undercut the price of traditional fertilizers.
“Farmers pay 20% to 25% less for nitrogen from our product than they do for synthetic nitrogen,” Abbott told me. “Prices [for traditional fertilizers] are going up again this spring, like they did last year. So that gap is actually widening, not shrinking.”
Peer reviewed studies also show that Pivot’s treatments boost yields for corn — its flagship crop — while preliminary data indicates that the same is true forcotton, which Pivot expanded into last year. The company also makes fertilizers for wheat, sorghum, and other small grains.
Pivot is now selling these products in stores where farmers already pick up seeds and crop treatments, rather than solely through its independent network of sales representatives, making the microbes more likely to become the default option for growers. But they won’t completely replace traditional fertilizer anytime soon, as Pivot’s treatments can still meet only about 20% to 25% of a large-scale crop’s nitrogen demand, especially during the early stages of plant growth, though it’s developing products that could push that number to 50% or higher, Abbott told me.
All this could have an astronomical environmental impact if deployed successfully at scale. “From a water perspective, we use about 1/1000th the water to produce the same amount of nitrogen,” Abbott said. From an emissions perspective, replacing a ton of synthetic nitrogen fertilizer with Pivot Bio’s product prevents the equivalent of around 11 tons of carbon dioxide from entering the atmosphere. Given the quantity of Pivot’s fertilizer that has been deployed since 2022, Abbott estimates that scales to approximately 1.5 million tons of cumulative avoided CO2 equivalent.
“It’s one of the very few cases that I’ve ever come across in climate tech where you have this giant existing commodity market that’s worth more than $100 billion and you’ve found a solution that offers a cheaper product that is also higher value,” Rinzler told me. BEV led the company’s Series B round back in 2018, and has participated in its two subsequent rounds as well.
Meanwhile, Nitricity — a startup spun out of Stanford University in 2018 — is also aiming to circumvent the Haber–Bosch process and replace ammonia-based and organic animal-based fertilizers such as manure with a plant-based mixture made from air, water, almond shells, and renewable energy. The company said that its proprietary process converts nitrogen and other essential nutrients derived from combusted almond shells into nitrate — the form of nitrogen that plants can absorb. It then “brews” that into an organic liquid fertilizer that Nitricity’s CEO, Nico Pinkowski, describes as looking like a “rich rooibos tea,” capable of being applied to crops through standard irrigation systems.
For confidentiality reasons, the company was unable to provide more precise technical details regarding how it sources and converts sufficient nitrogen into a usable form via only air, water, and almond shells, given that shells don’t contain much nitrogen, and turning atmospheric nitrogen into a plant-ready form typically involves the dreaded Haber–Bosch process.
But investors have bought in, and the company is currently in the midst of construction on its first commercial-scale fertilizer factory in Central California, which is expected to begin production this year. Funding for the first-of-a-kind plant came from Trellis Climate and Elemental Impact, both of which direct philanthropic capital toward early-stage, capital-intensive climate projects. The facility will operate on 100% renewable power through a utility-run program that allows customers to opt into renewable-only electricity by purchasing renewable energy certificates,
Pinkowski told me the new plant will represent a 100‑fold increase in Nitricity’s production capacity, which currently sits at 80 tons per year from its pilot plant. “In comparison to premium conventional fertilizers, we see about a 10x reduction in emissions,” Pinkowski told me, factoring in greenhouse gases from both production and on-field use. “In comparison to the most standard organic fertilizers, we see about a 5x reduction in emissions.”
The company says trial data indicates that its fertilizer allows for more efficient nitrogen uptake, thus lowering nitrous oxide emissions and allowing farmers to cut costs by simply applying less product. According to Pinkowski, Nitricity’s current prices are at parity or slightly lower than most liquid organic fertilizers on the market. And that has farmers really excited — the new plant’s entire output is already sold through 2028.
“Being able to mitigate emissions certainly helps, but it’s not what closes the deal,” he told me. “It’s kind of like the icing on the cake.”
Initially, the startup is targeting the premium organic and sustainable agriculture market, setting it apart from Pivot Bio’s focus on large commodity staple crops. “You saw with the electrification of vehicles, there was a high value beachhead product, which was a sports car,” Pinkowski told me. “In the ag space, that opportunity is organics.”
But while big-name backers have lined up behind Pivot and Nitricity, the broader ag tech sector hasn’t been as fortunate in its friends, with funding and successful scale-up slowing for many companies working in areas such as automation, indoor farming, agricultural methane mitigation, and lab-grown meat.
Everyone’s got their theories for why this could be, with Lara Pierpoint of Trellis telling me that part of the issue is “the way the federal government is structured around this work.” The Department of Agriculture allocates relatively few resources to technological innovation compared to the Department of Energy, which in turn does little to support agricultural work outside of its energy-specific mandate. That ends up meaning that, as Pierpoint put it, ”this set of activities sort of falls through the cracks” of the government funding options, leaving agricultural communities and companies alike struggling to find federal programs and grant opportunities.
“There’s also a mismatch between farmers and the culture of farming and agriculture in the United States, and just even geographically where the innovation ecosystems are,” Emily Lewis O’Brien, a principal at Trellis who led the team’s investment in Nitricity, told me of the social and regional divides between entrepreneurs, tech investors and rural growers. “Bridging that gap has been a little bit tricky.”
Still, investors remain optimistic that one big win will help kick the money machines into motion, and with Pivot Bio and Nitricity, there are finally some real contenders poised to transform the sector. “We’re going to wake up one day and someone’s going to go, holy shit, that was fast,” Abbott told me. “And it’s like, well you should have been here for the decade of hard work before. It’s always fast at the end.”
The most popular scope 3 models assume an entirely American supply chain. That doesn’t square with reality.
“You can’t manage what you don’t measure,” the adage goes. But despite valiant efforts by companies to measure their supply chain emissions, the majority are missing a big part of the picture.
Widely used models for estimating supply chain emissions simplify the process by assuming that companies source all of their goods from a single country or region. This is obviously not how the world works, and manufacturing in the United States is often cleaner than in countries with coal-heavy grids, like China, where many of the world’s manufactured goods actually come from. A study published in the journal Nature Communications this week found that companies using a U.S.-centric model may be undercounting their emissions by as much as 10%.
“We find very large differences in not only the magnitude of the upstream carbon footprint for a given business, but the hot spots, like where there are more or less emissions happening, and thus where a company would want to gather better data and focus on reducing,” said Steven Davis, a professor of Earth system science in the Stanford Doerr School of Sustainability and lead author of the paper.
Several of the authors of the paper, including Davis, are affiliated with the software startup Watershed, which helps companies measure and reduce their emissions. Watershed already encourages its clients to use its own proprietary multi-region model, but the company is now working with Stanford and the consulting firm ERG to build a new and improved tool called Cornerstone that will be freely available for anyone to use.
“Our hope is that with the release of scientific papers like this one and with the launch of Cornerstone, we can help the ecosystem transition to higher quality open access datasets,” Yohanna Maldonado, Watershed’s Head of Climate Data told me in an email.
The study arrives as the Greenhouse Gas Protocol, a nonprofit that publishes carbon accounting standards that most companies voluntarily abide by, is in the process of revising its guidance for calculating “scope 3” emissions. Scope 3 encompasses the carbon that a company is indirectly responsible for, such as from its supply chain and from the use of its products by customers. Watershed is advocating that the new standard recommend companies use a multi-region modeling approach, whether Watershed’s or someone else’s.
Davis walked me through a hypothetical example to illustrate how these models work in practice. Imagine a company that manufactures exercise bikes — it assembles the final product in a factory in the U.S., but sources screws and other components from China. The typical way this company would estimate the carbon footprint of its supply chain would be to use a dataset published by the U.S. Environmental Protection Agency that estimates the average emissions per dollar of output for about 400 sectors of the U.S. economy. The EPA data doesn’t get down to the level of detail of a specific screw, but it does provide an estimate of emissions per dollar of output for, say, hardware manufacturing. The company would then multiply the amount of money it spent on screws by that emissions factor.
Companies take this approach because real measurements of supply chain emissions are rare. It’s not yet common practice for suppliers to provide this information, and supply chains are so complex that a product might pass through several different hands before reaching the company trying to do the calculation. There are emerging efforts to use remote sensing and other digital data collection and monitoring systems to create more accurate, granular datasets, Alexia Kelly, a veteran corporate sustainability executive and current director at the High Tide Foundation, told me. In the meantime, even though sector-level emissions estimates are rough approximations, they can at least give a company an indication of which parts of their supply chain are most problematic.
When those estimates don’t take into account country of origin, however, they don’t give companies an accurate picture of which parts of their supply chains need the most attention.
The new study used Watershed’s multi-region model to look at how different types of companies’ emissions would change if they used supply chain data that better reflected the global nature of supply chains. Davis is the first to admit that the study’s findings of higher emissions are not surprising. The carbon accounting field has long been aware of the shortcomings of single-region models. There hasn’t been a big push to change that, however, because the exercise is already voluntary and taking into account global supply chains is significantly more difficult. Many countries don’t publish emissions and economic data, and those that do use a variety of methods to report it. Reconciling those differences adds to the challenge.
While the overall conclusion isn’t surprising, the study may be the first to show the magnitude of the problem and illustrate how more accurate modeling could redirect corporate sustainability efforts. “As far as I know, there is no similar analysis like this focused on corporate value chain emissions,” Derik Broekhoff, a senior scientist at the Stockholm Environment Institute, told me in an email. “The research is an important reminder for companies (and standard setters like the Greenhouse Gas Protocol), who in practice appear to be overlooking foreign supply chain emissions in large numbers.”
Broekhoff said Watershed’s upcoming open-source model “could provide a really useful solution.” At the same time, he said, it’s worth noting that this whole approach of calculating emissions based on dollars spent is subject to significant uncertainty. “Using spending data to estimate supply chain emissions provides only a first-order approximation at best!”
The decision marks the Trump administration’s second offshore wind defeat this week.
A federal court has lifted Trump’s stop work order on the Empire Wind offshore wind project, the second defeat in court this week for the president as he struggles to stall turbines off the East Coast.
In a brief order read in court Thursday morning, District Judge Carl Nichols — a Trump appointee — sided with Equinor, the Norwegian energy developer building Empire Wind off the coast of New York, granting its request to lift a stop work order issued by the Interior Department just before Christmas.
Interior had cited classified national security concerns to justify a work stoppage. Now, for the second time this week, a court has ruled the risks alleged by the Trump administration are insufficient to halt an already-permitted project midway through construction.
Anti-offshore wind activists are imploring the Trump administration to appeal this week’s injunctions on the stop work orders. “We are urging Secretary Burgum and the Department of Interior to immediately appeal this week’s adverse federal district court rulings and seek an order halting all work pending appellate review,” Robin Shaffer, president of Protect Our Coast New Jersey, said in a statement texted to me after the ruling came down.
Any additional delays may be fatal for some of the offshore wind projects affected by Trump’s stop work orders, irrespective of the rulings in an appeal. Both Equinor and Orsted, developer of the Revolution Wind project, argued for their preliminary injunctions because even days of delay would potentially jeopardize access to vessels necessary for construction. Equinor even told the court that if the stop work order wasn’t lifted by Friday — that is, January 16 — it would cancel Empire Wind. Though Equinor won today, it is nowhere near out of the woods.
More court action is coming: Dominion will present arguments on Friday in federal court against the stop work order halting construction of its Coastal Virginia offshore wind project.
