House Republicans’ new plan to transform NEPA, explained

A powerful House Republican committee has proposed shaking up one of the country’s key permitting laws as part of the ongoing process to write President Trump’s tax bill.
A new bill, drafted by the House Natural Resources Committee would transform the National Environmental Policy Act, or NEPA. Under NEPA as it stands today, the government must study the environmental impact of any “major” federal action. Any time a federal agency adopts a new policy, builds a new project, spends federal dollars, or issues a license or permit, that choice gets a full environmental review.
Crucially, this also means that the federal government must study the environmental impact even of privately developed projects that require some kind of federal sign-off. But the new bill would quicken this process and likely shield it from court review.
The law represents a “big step” for permitting reform, Nicholas Bagley, a University of Michigan law professor, told us. “It’s creative and extremely aggressive.” If it passes, Republicans’ budget measure could speed up the construction of energy projects around the country. But it could also reduce local or environmental groups’ ability to sue to slow down or block development.
The bill would allow companies to pay a fee to access a faster, more streamlined NEPA process that would not be reviewable by the courts, according to the bill. That means environmental groups would likely have a harder time suing the government for failing to account for various environmental maladies in their study.
Under the draft legislation, companies would pay 125% of the cost of preparing the report to get an expedited review. But avoiding a lengthy court fight is so valuable that many companies would likely take advantage of this new process, Bagley told us.
“You can read it as effectively creating a price for a litigation shield — the federal government is allowing developers to buy themselves out of litigation risk with a flat fee,” he said.
It would change the status quo in two important ways.
First, many federal agencies already require project sponsors to pay the full cost of preparing a NEPA report for a private project, such as a solar farm or geothermal well. The House Republican proposal would increase this cost by just 25% on the front end.
Second, under the law today, agencies take more than four years on average to prepare a NEPA report, which can regularly stretch into the hundreds of pages. Congress has periodically tried to impose tighter deadlines and shorter page limits on the NEPA process — including in a 2023 debt ceiling law — but it hasn’t been successful.
That’s because the threat of lawsuits ultimately drives the NEPA process, Bagley said. Civil servants write lengthy, meticulous NEPA reports not because statute requires them to do so, but because they’re afraid of losing their work in a lawsuit, he said.
“The thing driving lengthy timelines is litigation risk,” Bagley told us. “Unless and until you correct for the threat of judicial review, NEPA reform isn’t going to go that far.” This proposal is the first modern NEPA report to offer protection from judicial review.
The proposal could help speed up all types of energy projects.
But it could help some more than others. Certain fossil fuel projects — especially those involving fracking — have already received some form of exemption from the NEPA process. But renewables and clean energy projects broadly don’t have such a carve-out. Neither do some other types of natural gas infrastructure, such as pipelines and export terminals. These projects could benefit from a faster and less court-reviewable NEPA process.
This is the big question. To comply with the strictures of what’s known as the “Byrd Rule,” provisions in reconciliation must be primarily budgetary in nature, i.e. related to taxing and spending.
Provisions that have a budgetary effect but are “merely incidental” to their non-budgetary components can be ruled by the Senate Parliamentarian to be “extraneous” and excluded from the bill.
Parliamentarian rulings helped shape — and narrow — Democratic proposals in 2021 and 2022, including stripping out immigration provisions and minimum wage hikes from various bills that were working their way through the reconciliation process.
So where does overhauling NEPA fit in? The 125% fee makes the provisions of the House language arguably germane to the budgetary purposes of the reconciliation package. Supporters of the language will cite a precedent in the Inflation Reduction Act that waived judicial review for the program’s negotiation of drug prices in Medicare.
One way the parliamentarian will try to answer this question is by asking, “‘Is that big policy change necessary in order to achieve the budgetary impact?’ That’s the place where this could fail,” Thomas Hochman, the director of infrastructure policy at the Foundation of American Innovation, told us.
NEPA isn’t the only law that requires the government to study the environmental or cultural impact of its decisions. A handful of other laws — including the Endangered Species Act, the National Historic Preservation Act, or the Clean Water Act — mandate their own permitting process, which can also be lengthy.
Many of these laws impose substantive obligations on government decisions. The NHPA, for instance, requires the government to study whether any decisions will affect Native American cultural sites and to reach an agreement about how to mitigate that impact. These decisions can then be reviewed by the courts — NHPA was at the heart of the Dakota Access pipeline and SunZia cases.
Under the law today, the government often satisfies its duties under these laws as part of a broader “NEPA process,” with one agency essentially handling the paperwork for all the federal permitting laws that matter to a project together.
The House Republican proposal wouldn’t weaken or affect any of these laws, Hochman and Bagley told us. The government would still need to satisfy its obligations under all other federal permitting laws, and the courts could still review those decisions. It’s unclear how those laws would fit into the new streamlined NEPA process.
Senator Joe Manchin of West Virginia led two efforts during the Biden years to pass permitting reform legislation through the conventional lawmaking process. The bills tended to combine policy asks from Republicans and Democrats — that is, oil and gas interests as well as green energy and transmission developers — in an effort to build a broad consensus in favor of policy change.
What that looked like in practice was specific carveouts designed to facilitate the building of long-range transmission lines alongside, say, changes in schedules for leases for extracting fossil fuels on public lands.
This time, Republicans alone are driving the permitting reform process, because the reconciliation bill is expected to be approved (or not) on party lines.
The reconciliation language says nothing specific about transmission, for example, but it includes specific provisions favored by the oil and gas industry like mandating lease sales on a quarterly basis. The American Petroleum Institute praised the bill, and the Sierra Club said that “the only way it could be friendlier to Big Oil CEOs would be if they wrote it themselves.”
But the reform to how NEPA is — and isn’t — litigated is a genuine breakthrough in years of drawing up failed permitting reform plans.
“We haven’t yet seen one bipartisan bill on permitting that broadly amends judicial review,” Xan Fishman, senior managing director of the energy program at the Bipartisan Policy Center, told us.
“One of the difficulties in doing permitting reform is that there isn’t just one problem that needs solving. There are a bunch of things that all add up to a really difficult process that takes a long time and has massive degrees of uncertainty,” Fishman said.
To the extent clean energy projects face sometimes fatal delays due to the specific rigors of the NEPA process, the bill would remove a barrier to their development.
NEPA has proven to be a significant barrier to solar development. About two thirds of solar projects that were assessed under NEPA between 2010 and 2018 faced litigation, as well as almost one third of pipelines and 38% of wind projects, according to Stanford researchers Michael Bennon and Devon Wilson.
Even when agencies win court cases — which can be filed up to six years after a federal agency decision — “litigation overwhelmingly functions as a form of delay,” according to Breakthrough Institute research.
It’s unclear whether the House Republican proposal will ultimately speed up federal energy project approvals, or whether litigants will shift to opposing projects under other permitting laws, such as the Endangered Species Act or NHPA. But permitting reform advocates agree that the proposal nonetheless represents a big step.
“It would be a pretty good shield for persnickety criticisms of [environmental reviews] that are now de rigueur, but it might not provide complete protection from the full run of environmental objections waged against a project,” Bagley said.
“I am firmly convinced that NEPA is a big problem for helping to create and reinforce defensiveness on the part of agency officials. But it’s part of a big web of accountability run maybe too amok,” he said. “One answer is to start clipping parts of the web — it doesn’t fix the whole problem, but it might help you see what else becomes salient.”

My colleague Emily Pontecorvo has a fascinating story today about Net Power, an energy and power development company whose technology once seemed key to decarbonizing the country’s electricity grid.
When Net Power went public in 2023, it was working on a natural gas-burning power plant that would generate little to no emissions in part by using carbon capture and storage. Its invention seemed to have big implications, and not just for the company’s bottom line: Back then, the Environmental Protection Agency was drafting climate rules that would have required new natural gas plants built in the 2030s to capture their carbon dioxide emissions. Net Power’s technology seemed like one of the best available ways to meet that standard.
Cut to 2026, and the world looks different. Thanks to the artificial intelligence boom, electricity demand is surging. But Net Power hasn’t successfully commercialized its proprietary power plant technology. Even if it had, few companies are willing to pay the high premium required by Net Power’s technology, especially when cheaper options are available. And the government certainly isn’t going to require it. Emily’s story reveals what happened next.
When I helped start Heatmap more than three years ago, I never thought I would write this much about data centers. I believed that electricity demand growth was inevitable, sure, and I thought the U.S. power grid had to expand for the country to decarbonize. But I didn’t foresee such a staggering near-term surge in electricity demand. (To be fair, even long-time students of the computing industry’s energy use didn’t see the coming increase, either.)
What I didn’t anticipate — or understand — were two fast-moving trends. The first was that the AI models were responding to scale: the more text or images they consumed, or training they received, or (crucially) computational power they had access to, the better they got. The second was that Wall Street was happy to pay to continue that speedy scale-up. As long as models kept getting better, investors were willing to keep lending or investing more money to the companies making them. Through the power of those two scaling functions, the data center boom became one of the biggest infrastructure buildouts in American history.
In recent days, the second of those trends has started to falter. After a surprisingly hot inflation report last week, and a disclosure on Wednesday evening that Meta has gone free cash flow negative to finance its ongoing AI buildout, stocks with any proximity to AI or data centers stumbled on Wall Street today. The data center developers Coreweave and Vistra were each down about 10%, while Microsoft, Alphabet, and Nvidia all fell in daily trading. Meta’s stock lost almost 7% of its value; GE Vernova, which produces gas turbines, was down 10%.
These declines look more significant when you zoom out. Since late June, a good chunk of the AI portfolio has sagged into the red. Coreweave’s stock is down 54% over the past six months. Alphabet and GE Vernova have also posted declines since the summer. (The trend isn’t uniform: Nvidia and Microsoft are still very much in the green.)
None of this, to be sure, guarantees that the AI boom is ending or even slowing down. But this finance-applied friction is what such a slowdown could look like. Investors aren’t (yet) saying that AI is a business dud, to be clear, just that companies perhaps don’t need to go and construct all this stuff so fast. And given what the data center buildout has meant for energy construction — not to mention greenhouse gas emissions — that’s a trend nobody in climate or energy can ignore.
The zero-emission pioneer is doing the dirty work for the AI boom.
All kinds of companies have refashioned themselves to exploit the AI boom. A bitcoin miner became a data center developer, a shoemaker is building GPUs, and an electric vehicle company is integrating its powertrains into server racks.
Now, a company that once aspired to build one of the lowest-emitting power plants has pivoted to building one of the dirtiest in order to meet data centers’ requirement for speed to power above all. Net Power was founded to pioneer a new form of natural gas power plant with zero emissions, but it has given up on that technology and recently acquired 10 natural gas reciprocating engines that it plans to co-locate with a data center on the site intended for its first commercial plant.
“We believe the clean piece is important,” Net Power CEO Danny Rice said during an August earnings call when he announced the company’s pivot to building unabated natural gas plants. “But just as it’s always been, it will only come at scale once society’s basic energy pillars of reliable, affordable power are fully in place. Power demand is outstripping supply today.”
Net Power’s pivot is a sign not only that the AI boom has eroded market appetite for clean power, but that U.S. policies supporting carbon capture — primarily the 45Q tax credit that President Trump’s One Big Beautiful Bill Act recently expanded — are still not enough to support the technology’s deployment in the power sector.
“The long history of doing CCS in the United States is there isn’t enough public funding to get companies to deploy it at scale,” Jack Andreasen Cavanaugh, a senior research associate at Columbia University’s Center on Global Energy Policy, told me.
This is actually the second major pivot the company has made in less than a year. Last November, Net Power was still testing its proprietary oxy-combustion technology at its demonstration site in La Porte, Texas. The tech was designed to burn natural gas in a chamber with pure oxygen, producing a purer stream of CO2 than when natural gas is burned in regular air. Net Power’s system could recycle some of that CO2 for power generation and capture the rest more efficiently than a conventional gas plant could. The company had not yet demonstrated that the system could generate more energy than it used, however.
By that point, Net Power had determined that its oxy-combustion plants, if they ever even did generate net power, would not be economically competitive anytime soon. In its 2025 Q3 financial report, the company said it had “decided to broaden the scope of its business” and develop more conventional natural gas plants with carbon capture equipment tacked on. It signed a letter of intent with Entropy, a Canadian company building “post-combustion” carbon capture equipment, to bring the tech to the United States, and ordered two 30-megawatt Siemens natural gas turbines for 2028 delivery.
“For us and everyone else in the power and data center space these days, speed is everything,” Rice said at the time. “We believe gas turbines with [post-combustion capture] can and should be the fastest-to-market and most cost-competitive clean, firm solution for our prospective customers.”
He told investors that rising costs were one of the setbacks Net Power faced in building its first-of-a-kind oxy-combustion plant. It was highly unlikely the company could finance and build a $1.7 billion, 200-megawatt plant before completing all its testing, he said. The best-case scenario for the plant to come online was 2030 or 2031, and costs might keep rising with inflation. The company could either bet on that prospect and keep bleeding cash, or “slow down that spending in order to free up some of our resources for near-term accretive opportunities.” As a public company with shareholders to answer to, there was really only one choice.
By the end of 2025, Net Power decided to suspend its oxy-combustion development and testing activities altogether, according to its year-end SEC filing.
Six months later, the company’s thesis changed again. Gas turbines with post-combustion capture, it turned out, were not the “fastest-to-market and most cost-competitive” solutions that the company had hoped they’d be. Whereas once upon a time, electricity buyers considered a range of factors when shopping around for power, including carbon emissions, the reality was that they were now only looking for three qualities: speed, reliability, and scale. “Natural gas power generation, co-located with customer load, and deployable on a fast timeline, is how we expect to meet that demand today,” Rice told investors, adding that the company hoped to add carbon capture to its projects in the future.
To date, only one proposed U.S. natural gas plant with carbon capture has announced a deal to sell its prospective power. In October 2025, Google signed a power purchase agreement with the Broadwing Energy Center, an Illinois plant under development by a company called Low Carbon Infrastructure.
“There is a massive demand for unabated gas right now, and there is much less of a demand for carbon capture,” Cavanaugh said. He told me there are still lots of conversations happening between hyperscalers and carbon capture companies, but the physical realities and costs of capturing, transporting, and storing carbon from natural gas plants remain obstacles.
The Global CCS Institute published its annual Global Status of CCS report this week, which found more than 266 carbon capture, transport, or storage projects are under development in the U.S., but permitting delays and policy uncertainty are stalling their progress. “Inflation and rising capital costs have weakened project economics, reducing the effectiveness of existing policies, such as tax and investment credits,” the report said.
That doesn’t mean there aren’t still companies trying. Net Power may have given up on oxy-combustion power plants for now, but Arbor Energy, a startup founded by former SpaceX engineers, is just ramping up. Arbor announced a milestone in the development of its own oxy-combustion power generator last week, running a key piece of its system — a supercritical CO2 turbocompressor — for more than two hours at high speeds.
Arbor differentiates itself by using 3D-printed turbines and developing smaller, more modular plants. It’s scaling more incrementally than Net Power tried to, starting with a 1-megawatt demonstration plant in California that is “weeks away” from operating, the company’s Chief Operating Officer Alicia Harmon told me — although the project won’t include carbon storage. It plans to build a 25-megawatt demonstration plant by 2028, also sans storage, before manufacturing commercial-scale systems.
Arbor actually went through a pivot of its own due to the data center boom. The founders originally planned to focus on bioenergy with carbon removal, using the oxy-combustion technology to generate power from biomass and storing the resulting CO2 underground. Over time, though, it became clear that demand for power outpaced demand for carbon removal, and natural gas was more abundant than biomass.
I asked Harmon whether the company thought there was market demand for carbon-capture gas plants. Is anyone willing to pay that green premium right now? “Honestly, my answer is no,” she said, but the company sees a path to erasing the green premium by the early 2030s. She added that Arbor’s technology is already “very close” to parity with combined-cycle natural gas plants when the 45Q tax credit is taken into account.
Last month, Net Power announced it had acquired 123 megawatts’ worth of Wärtsilä reciprocating engines, in addition to the Siemens turbines it had already ordered. Reciprocating engines are among the dirtiest natural gas power-generation technologies. A recent report from Earthjustice estimated that a 1-gigawatt plant powered by reciprocating engines would emit 1.5 times as much CO2 per year as one powered by the “combined cycle” technology most modern plants use, and twice as much nitrogen oxides and fine particulate matter. It has not yet disclosed any data center partners to sell the power to.
Net Power declined to comment on this story.
Ben Allen wants to reform the existing market. Jane Kim wants a revolution.
From Crescent City to Coronado, California voters are facing decisions on a down-ballot strewn with over a dozen propositions and a series of statewide Democrat-versus-Republican races with mostly foregone conclusions.
And then there’s the insurance commissioner.
In the race to oversee California’s insurance market, a $452 billion-in-premium-volume monster imperiled by insurer defections and disaster risks, Democratic State Senator Ben Allen, whose district includes Pacific Palisades, is facing off against Jane Kim, a progressive former San Francisco supervisor.
Kim has the support of Vermont Senator Bernie Sanders — it’s the first thing you see about her when you Google her campaign. She previously served as his California political director during the 2020 presidential race, and she appeared earlier this month at an event with the senator in support of the state’s proposed billionaire wealth tax.
Allen, by contrast, won the endorsement of the state’s Democratic Party and its two incumbent senators.
There has been little public polling of the race, but one September survey showed Kim leading Allen 25% to 18%, with more than half the electorate undecided.
“My opponent and I are not even running for the same office,” Kim told me. “He’s running for what this office used to be, and I’m running for what this office could be.”
Allen wasn’t worried about Kim’s characterization in my interview with him, telling me, “I want to fix the market that we have and make it work. My opponent wants to build a new state insurer that nobody has priced.”
Nowhere are the stakes of insurance regulation higher than in California. On its own, the state’s insurance market would be the third largest in the world, according to the National Association of Insurance Commissioners. Homeowner insurance premiums have risen 84% from the end of 2020 to March 2026, according to research from Stanford’s Climate and Energy Policy Program. Several large insurers have either left the market entirely or stopped writing new policies.
California’s creaky and complex regulatory environment for insurers has combined with its famously flammable environment (all beset by a warming climate) to put regular policyholders at risk of losing their policies or bailing out those who can’t get covered. “Climate risks grow, and our mechanisms for dealing with it lag behind,” Matt Weiner, the chief executive of the wildfire policy group Megafire Action, told me. (Weiner said he was supporting Allen in his personal capacity).
Rates for homes insured by the FAIR Plan, the barebones insurer of last resort, have more than doubled from about 2% to 5% over that same period, with FAIR Plan coverage spreading from just high-risk areas to even areas with low and moderate wildfire risk. The plan required a $1 billion assessment from the state’s insurers in 2025 following major Southern California fires. “This trend is a symptom of many homeowners’ inability to secure insurance in the conventional market,” according to the Stanford researchers.
Allen seeks to make the insurance market work better, building on reforms implemented by current Insurance Commissioner Ricardo Lara. Allen described the reforms, which encourage insurers to write policies in high-risk areas and allow them to use forward-looking projections, as a “bit of a band-aid” that doesn’t “actually get to the core of the problem, which is making these communities less risky.”
Allen’s plan for the California insurance market involves both reviewing rate proposals more quickly, incorporating more data into those rates (which may push rates up, but also keep insurers in the market), and mobilizing the whole of government to invest in home hardening and resilience to lower risk and bring premiums down. Allen wants to, well, insure “that risk reduction is actually incentivized and rewarded by the insurance market,” he told me.
This would mean that “there will continue to be certain properties that are going to be so high risk that they really will and ought to be paying significantly more than everybody else,” he added.
When I asked him to elaborate on his vision for California’s insurance future, he told me, “My hope is that when a family and a neighborhood commit to hardening defensible space and community-scale mitigation, that should show up on the bill.”
Jane Kim, on the other hand, is interested in an insurance revolution, which would require — as her most famous supporter might put it — a political revolution as well. Her centerpiece proposal will be familiar from anyone who has followed Sanders’ career: a single-payer disaster insurer.
The plan, which she told me was a “concept and a proposal,” would be funded by a levy placed on insurers, and then a public insurer would invest in the market, buy reinsurance, and pay out claims. (Her opponents have criticized her for not being forthcoming enough with details). She says her plan would not be able to cover a Palisades- or Altadena-level fire in its first year, “but no insurance company can cover a catastrophe of that level.”
The nonprofit nature of the program, she adds, would let the state fund mitigation work directly. While such a program would require legislative action, “the great thing about campaigns is that this is trying to debate big ideas with voters,” Kim said.
In response, Allen cited a report from the California Earthquake Authority, which modeled a state disaster insurer (albeit not Kim’s plan specifically) could require $25 billion in capitalization. A more thinly capitalized insurer could mean $2,000 assessments on every policyholder in the state to cover an extreme wildfire disaster, the report said. “That’s the honest price of what she’s proposing,” Allen said.
“I also have a plan that’s actually grounded in reality and fixing the problems right now. It's not based on some pie-in-the-sky set of ideas that have no precedent, that have no real meat on the bones,” Allen told me.
One of Allen and Kim’s former opponents, Patrick Wolff, who fell short in the top-two primary election in June, told me that “the charitable interpretation of Kim’s platform is she does not think the current system can be made to work, and so she essentially wants to redesign and reimagine the entire system.” (Wolff has endorsed Allen). But, he added, “she’s coming at it from a set of solutions that were baked-in before she started, and then she's fitting [those] into her campaign.”
Moira Birss, a senior fellow at the Climate and Community Institute who said she had “provided input” to Kim’s campaign, but wasn’t speaking on its behalf, told me she “really recognizes that we are yet again in a situation where the private insurance market is not responding to a need that we as communities and as society have for this financial safety net of disaster insurance, and that we need a public approach.” She said the plan would build on lessons learned from New Zealand, which has public natural disaster insurance funded through a levy on fire insurance, and from the National Flood Insurance Program and the FAIR Plan.
Kim is happy to embrace the more ideologically charged vision of her campaign, telling me, “I am talking about transforming this office to be a place where we are leading on, and taking on, economic inequity, a wealth gap, and the climate crisis.
“I don’t even view my opponent as Ben Allen — I’m not running against Ben Allen,” she went on. “I’m running against the status quo.”
