A guide to the year’s biggest environmental fight — and some of the most important changes that could result.

Pending catastrophe, the most important environmental policy debate in Washington this year will be about a set of questions that have come to be known as “permitting reform.”
Essentially, the government is poised to change the laws and procedures that govern how it approves new infrastructure, from highways to subways, wind farms to oil pipelines. The outcome of the debate will alter how America fights climate change and builds clean energy — and whether it further embraces fossil fuels.
Some of the oldest ideas in American environmental law are up for grabs. For the first time in decades, both parties want something to change about the country’s permitting process: Republicans want to loosen federal environmental reviews; while Democrats want to simplify and speed up how new electricity transmission is built, which would inherently boost renewables. That should make a deal possible — and indeed, lawmakers have entertained striking a bargain in a deal to raise the debt ceiling.
Yet permitting reform is unusually hard to follow. As of May 2023, at least six different bills are floating around Congress: House Democrats, Senate Democrats, House Republicans, and Senate Republicans have each proposed a bill (or two), as has Senator Joe Manchin of West Virginia, a key moderate who leads the Senate’s energy committee. Each of these bills consists of dozens of unique policies and proposals, and their goals range from hastening the end of oil to rejuvenating fossil fuels.
Below we’ve compiled a cheat sheet on some of the biggest questions in the 2023 permitting-reform debate without getting into the weeds of each separate bill. We’ll update it as the process continues.

It’s really hard to build new power lines in the United States — especially the kind of long-distance, high-voltage power lines that can move electricity across the country.
Because a shortage of power lines is holding back America’s renewables revolution. With a bigger, more interconnected grid, you can link the country’s windiest, sunniest areas to its power-hungry cities and suburbs, and balance out electricity demand across regions.
If America doesn’t double its rate of power-line construction, then 80% of the carbon benefits from Biden’s climate law will be lost, according to an analysis from Jesse Jenkins, a Princeton engineering professor.
Building a new transmission line requires getting approval from dozens of organizations along a proposed route, including every city, county, and state government. (Building a pipeline is much easier.) And utilities along the route have to agree about how to divide up its costs.
They want to give the Federal Energy Regulatory Commission, a bipartisan panel usually called FERC, the authority to decide where new interstate power lines should go and who should pay for them. (FERC already has that power over natural-gas pipelines.)
Democrats also want FERC to require each region to have a baseline amount of transmission with its neighbors, and to open an office that will manage and coordinate new transmission projects.
They haven’t proposed much, although the Senate GOP’s bill would prevent a president from blocking a cross-border pipeline or transmission line — a not-so-veiled attempt to help fossil fuels and avert another Keystone XL debacle.
His proposal would let FERC approve a new power line — but only if a state government has already blocked it for a year or more. He also wants FERC to set rules about who pays for a transmission project.

Every new power plant or renewable project has to enter the “interconnection queue” — effectively, a waiting list to get plugged into America’s jammed and overloaded power grid.
Because it keeps the grid from decarbonizing. The longer that new clean-energy projects have to wait in line, the longer that existing, dirty energy sources provide most of our electricity.
It now takes about four years for new projects to clear the interconnection queue, and more than 75% of renewable projects get canceled before they get to the front of the line.
At root, it’s because America doesn’t have enough power lines. But it’s also because in some places where the grid is clogged, utilities will force a wind or solar developer to pay not only for their own grid hookup, but also for crucial upgrades across the power grid — even those hundreds of miles from a project. That’s partially because the interconnect rules were written for companies building big coal and nuclear plants, not smaller renewable farms.
They want FERC to issue some ground rules about who can pay for grid upgrades, so that utilities can’t force renewable developers to foot the entire bill for them.
They haven’t proposed anything.
He hasn’t proposed anything.

Before a federal agency can build, approve, or change almost anything — whether it’s authorizing a space port or banning cars from a road in a city park — it must study how that action will impact the environment. It also must seek public comment and publish alternatives to its plan.
These studies, which are required by the National Environmental Policy Act (NEPA), can run thousands of pages long and take years to finish.
It’s not … depending on who you talk to. NEPA doesn’t require that the government actually change anything because of its study; only that it publishes it and seeks public comment. While environmentalists can’t use NEPA to block a polluting project, they can sue the government to get it to add information to an environmental-impact report, which can sometimes delay a project long enough for it to get canceled.
Some environmentalists say that NEPA is an important tool to waylay fossil-fuel development. (It’s how activists delayed the Dakota Access Pipeline for a year or so.) But others say that NEPA is now mostly slowing down the green transition, and that it has given “corporate interests and rich NIMBYs” a veto over rapid climate action.
It takes 4.5 years on average to finish an environmental-impact statement, the most stringent kind of NEPA review — but that’s an average. The NEPA review of renovations to Washington, D.C.’s main public-transit hub has taken eight years and counting.
When NEPA was first passed in 1969, supporters believed that it would give Americans an expansive new right to a healthy environment. Liberal lawyers hoped that NEPA might reorient all of federal policy in a greener direction, like the Civil Rights Act did for race and gender discrimination a few years earlier.
That didn’t happen. By the mid-1970s, the court system had hemmed in NEPA, turning it into a paperwork mandate, not a substantive right. That means NEPA lawsuits — of which there are more than 100 every year — feature a lot of bickering over procedural details.
Senate Democrats would impose a one-year deadline for light NEPA reviews and a two-year deadline for the most stringent reviews — but those deadlines would only apply to projects that fight or adapt to climate change, and there would be no penalty for missing them. The House bill asks the White House to write new rules for NEPA studies.
The GOP would require one- and two-year deadlines for NEPA studies, but for all types of projects, not just those related to climate change. If an agency missed those deadlines, then under the Senate GOP bill, the project being studied would immediately and irrevocably get approved. (The House GOP, meanwhile, would charge the offending agency a fine.)
Republicans would also impose a 300-page limit on NEPA studies for complex projects and a 150-page limit on most projects. Today, the average NEPA study is more than 500 pages long.
He’s proposed the same page limits and deadlines as Republicans, but with weaker penalties and no automatic approval.

Technically, NEPA doesn’t require that agencies look into whether a proposed federal project would worsen climate change. The Biden administration has required agencies to take it into account, but that could be reversed by a future administration.
It’s a little silly that the government would write a 500-page report about a project’s environmental impact — but not say anything about its carbon emissions.
Because every administration — and every agency — implements NEPA in a different way. The courts also set some ground rules about what a NEPA study must include, but the extremely conservative Supreme Court is unlikely to require NEPA studies to include climate effects anytime soon.
They want to require agencies to consider a project’s impact on the climate, including whether not doing the project would raise emissions.
House Republicans want to block agencies from considering climate change — or any negative environmental impacts more than 10 years in the future — when preparing a NEPA study.
Senate Republicans would also forbid FERC from considering whether any project would raise or lower emissions.
He hasn’t proposed anything.

NEPA fights never end. Americans generally have up to six years to sue the government over a NEPA study, and the ensuing court battles can take years to resolve.
Depends on who you ask. The lack of a deadline can create an aura of uncertainty around public projects: Years after a federal agency approves an infrastructure project (including a clean-energy project), that project can still be challenged and blocked in court — even if construction on it has already started.
For some progressives, that doesn’t seem so bad, because it lets environmental lawyers drag fossil-fuel companies into lengthy NEPA lawsuits over proposed pipelines or refineries. But other progressives argue that most new energy projects will be zero carbon anyway, so NEPA fights allow conservatives and NIMBYs to veto clean energy.
Because Congress didn’t envision the modern permitting process when it first passed NEPA, and the law doesn’t contain a statute of limitations.
Senate Democrats want to impose a three-year limit on bringing a NEPA lawsuit, and they’d immediately elevate a NEPA suit to the local federal appeals court. House Democrats haven’t proposed anything.
Republicans in both chambers want to add a three- or four-month statute of limitations to NEPA. Senate Republicans would go further and require the courts to rule on any NEPA case within six months. These litigation deadlines could sharply limit environmentalists’ ability to fight fossil-fuel infrastructure.
His bill would add a five-month statute of limitations to NEPA.

The federal offices that handle most of the NEPA-related paperwork don’t have enough employees and suffer high staff turnover, which slows down their ability to quickly finish the easiest studies.
According to some progressives, a lack of funding for the agencies that implement NEPA is the biggest driver of permitting-related slowdowns. They argue that the most common kind of NEPA studies are completed in a year or so, and that only the most stringent NEPA studies regularly drag on. (Plenty of federal actions, such as building a new train station or transmission line, require a stringent NEPA study.)
When legal scholars at the University of Utah looked at 41,000 NEPA decisions of all kinds made by the U.S. Forest Service, they found that most delays were caused by agency understaffing, turnover, or delays in getting information from applicants. They also blamed unstable budgets, inadequate technology, and conflicting guidance from other laws, such as those governing historical preservation.
A decade of federal cost-cutting, among other reasons. The Department of the Interior lost 6% of its staff during the Trump administration and has only gained 2% since. FERC has also struggled to hire qualified workers.
Senate Democrats would make every agency identify its NEPA workforce needs annually and then give it the power to hire accordingly. House Democrats would let FERC pay people more than normal federal law allows.
House Republicans would require the National Park Service, the Bureau of Land Management, and the U.S. Forest Service to prepare an outreach plan for hiring new permitting employees.
He’s proposed allowing FERC to exceed the federal payscale, too.

New geothermal plants could generate a huge amount of zero-carbon electricity. Yet securing a permit to install a geothermal plant on federal lands — where the richest geothermal resources exist — can take years.
Because it’s comparatively easy to drill for oil and natural gas on federal land: Oil and gas drilling is categorically exempt from parts of NEPA, and a special office in the Bureau of Land Management handles fossil-fuel permits. So even though geothermal firms use the same equipment as oil and gas companies — but don’t create the same carbon emissions — it is much harder to drill for geothermal energy, and therefore much more expensive.
About 90% of “viable geothermal resources” — places where it makes sense to drill for Earth’s heat — are located on federal lands in the West. This isn’t parkland, to be clear, but government-owned land now used for ranching, hunting, mining, or recreation.
Because geothermal is a new industry. Until recent improvements in drilling, geothermal only made sense in a few parts of the country. Now it could be used more widely.
Senate Democrats want the Interior Department to make sure geothermal drilling permits are handled in the same way that oil-and-gas drilling permits are.
House Republicans would exempt some geothermal projects from having to get permits at all. And Senate Republicans would tell the Interior Department to defer to state law when granting new geothermal permits.
While supportive of geothermal power, he hasn’t proposed anything on this issue.

Current conditions: The sun is coming out as New York City digs out of nearly two feet of snow, but temperatures are set to drop by 5 degrees Fahrenheit and more snow is forecast later this week • Floodwaters destroyed a major bridge in Migori, near Kenya’s shore of Lake Victoria, as rain continues every day this week across the country • The Solomon Islands are hunkering down in thunderstorms all week.

Electricity went out in more than 600,000 U.S. homes and businesses during the blizzard that pummeled the Northeast with two feet of snow. Massachusetts suffered the worst of the blackout, with nearly 300,000 customers still disconnected as of Monday night. New Jersey and Delaware trailed behind with more than 50,000 households each. In a show of the bicoastal nature of America’s grid fragility, intense winds in California also knocked out power lines and plunged tens of thousands more homes into darkness. Heavy snows put travel bans in effect across five states, but temperatures remained just above freezing in broad swaths of the country’s most densely populated region.
Winter Storm Fern, the Arctic weather that hit the Northeast at the end of last month, took out power for more than 1 million U.S. households, as I reported at the time. That’s due in part to the frigid air. As Heatmap’s Jeva Lange and Matthew Zeitlin wrote recently: “Put simply, cold temperatures stress the grid. That’s because cold can affect the performance of electricity generators as well as the distribution and production of natural gas, the most commonly used grid fuel. And the longer the grid has to operate under these difficult conditions, the more fragile it gets. And this is all happening while demand for electricity and natural gas is rising.”
The Supreme Court added just one new case to its oral argument docket upon returning Monday from its winter recess. The nation’s highest court has agreed to review a ruling by the Colorado Supreme Court in a case in which the oil and gas industry challenged Boulder County’s legal right to sue fossil fuel producers for damages from the effects of climate change under state law on the grounds that the companies knowingly destabilized the planet’s weather systems. In a lawsuit backed by Exxon Mobil, the Canadian fuel refiner Suncor Energy argued that the issues Boulder’s county commission cited in its suit fall under the federal government’s jurisdiction, thereby invalidating the basis for the litigation. While Colorado’s highest court said it aimed to “express no opinion on the ultimate viability of the merits of” Boulder’s claims when it rejected oil companies’ argument in 2023, the justices wrote that they believed the industry case boiled down to an argument that “a vague federal interest over interstate pollution, climate change, and energy policy must preempt Boulder’s claims.”
Heatmap’s Emily Pontecorvo laid out the stakes like this: “The case is arriving at the nation’s highest court in a particularly fraught moment for climate regulation. The Supreme Court ruled back in 2007 that the EPA had authority to regulate greenhouse gases under the Clean Air Act, preventing states from creating a patchwork of their own emissions rules.” The case has come before the Supreme Court five times already, according to SCOTUSblog.
Once derided as a “false solution” that posed grave risks across human endeavors — even to the scientific process itself — environmental advocates have begun quietly to embrace the need at least study what technologies to artificially cool the planet might do now that a private geoengineering industry is rapidly emerging. (To brush up, re-read all the context my colleague Robinson Meyer wove into his scoop last year on a leading geoengineering startup raising its first major financing round.) Now the Natural Resources Defense Council is officially taking geoengineering seriously. Alongside three other partners, the green group launched a new project Tuesday morning to coordinate research governance on solar radiation management, the controversial suite of technologies that largely involve spraying reflective aerosols into the atmosphere to reflect the sun’s energy back into space.
Dubbed the Solar Geoengineering Research Governnance Platform, the project “will provide shared, voluntary tools that help research institutions demonstrate how decisions are made, risks are managed, and public concerns are addressed.” The NRDC said laboratory and university partners would be unveiled in upcoming announcements. “Solar geoengineering research is advancing faster than governance systems can keep pace,” Alliance for Just Deliberation on Solar Geoengineering executive director Shuchi Talati, a nonprofit that’s part of the new effort, said in a statement. “The goal is to carefully co-develop thoughtful, practical governance tools before research expansion narrows public choice.”

Despite a storm of tariffs and seachanges in federal policy, clean energy finance in 2025 “proved less fragile than the year’s headlines suggested.” That’s the conclusion of a new year-end report Heatmap’s Matthew Zeitlin wrote up this morning by Crux Climate, the low-carbon fintech startup. “AI investment, data center development, delayed interconnection, and energy affordability reinforced the underlying investment case in 2025 for projects that could deliver power and reliability quickly and predictably,” the report found. “In this environment, clean energy and capital markets were remarkably resilient.” Investors gave out more capital than ever, but the market split. One on side, you had smaller developers, manufacturers, and biofuels companies that saw overall declining investment. On the other, you had soaring power investment.
The green steel startup Boston Metal, meanwhile, is cutting jobs after suffering what Canary Media called “a major setback.” The company said it had experienced an “unforeseen critical equipment failure” at its manufacturing plant in Brazil. While the incident was “fully contained, with no injuries or environmental impact,” the equipment damage prevented the startup from hitting an operational milestone needed to unlock a pending financial deal. As a result, “we lost access to committed capital essential to supporting our operations in both Brazil and the U.S.” Boston Metal is now laying off 71 employees in the U.S., amounting to nearly a quarter of its global workforce.
Amazon plans to pump $12 billion into new data center campuses in Louisiana, the company announced Monday. The push will create 540 full-time data center jobs and the tech giant will invest “up to $400 million in local water infrastructure” for the facilities. In a press release, the company pledged to pay for its own energy and utility infrastructure, and provide a $250,000 community fund to help support science education.
At least 25 data centers were abandoned last year following local opposition, according to a Heatmap Pro review that Rob wrote about last month. Data center fights, our colleague Jael Holzman wrote in November, are “swallowing American politics.”
Leave it to France to punch above its weight in nuclear energy. Last week, the WEST tokamak reactor at the French Commission of Atomic and Alternative Energies’ Cadarache laboratory broke a record in fusion energy. The reactor held a hot plasma for 1,337 seconds, slightly over 22 minutes. That beat the previous record set by a Chinese fusion facility weeks earlier by 25%. “WEST has achieved a new key technological milestone,” Anne-Isabelle Etienvre, the commission’s director of fundamental research, said in a statement. “Experiments will continue with increased power. This excellent result allows both WEST and the French community to lead the way for the future” large-scale experiments at the ITER international fusion research project.
Editor’s note: This story has been updated to correct the description of the Solar Geoengineering Research Governnance Platform, including the group’s name and purpose.
There are two titanic forces in the clean energy market, and whichever one is stronger will determine the path of the post-One Big Beautiful Bill Act industry.
First there’s federal policy, which, thanks to OBBBA and the Trump administration’s war on renewable permitting, is making things more difficult for developers. Then there’s the technology: Soaring electricity demand from data centers, providing the business case for everything from co-located batteries and solar to small modular nuclear reactors.
“2025 is the storm at night, and there were all these cross-cutting winds that hit the boat. The ones that came from the front are the tariffs and the tax changes and wind cancellations or pauses,” Alfred Johnson, cofounder and chief executive of the clean energy finance platform Crux, told me. “Then the tailwinds at the back were interest rates, the continuation of many [other tax credits] in the OBBBA — including storage credits, nuclear credits, manufacturing credits — and substantial demand coming for the electricity and the components. And when the storm cleared in the morning, the boat is further ahead in the water than you would have anticipated.”
That’s the bifurcated story Crux — a marketplace for tax equity, tax credits, and debt financing — is telling in its 2025 market intelligence report, released Tuesday. There were splits in when investment happened and in which sectors were favored. There were better and worse times for investment. And there were countervailing forces pushing on the clean energy market.
Here’s how Crux views the clean energy financing market as it enters an uncertain time.
Crux found a split in activity between the first and second halves of last year across a number of markets. A lot of that could be chalked up to investors trying to front-run a partial or full repeal of the Inflation Reduction Act, which became all but inevitable following the 2024 election.
Overall there was $120 billion worth of lending to “clean power, fuels, and manufacturing projects” in 2025. That’s more than in 2024, but still a “materially lower growth rate” — 5.8% year over year, compared to 22% in 2024.
“Investment activity was front-loaded during the first half of 2025,” the report found, peaking in the first three months of the year and then declining through “the second and third quarters “as some investors waited to see how debate over the OBBB would resolve itself.” There was capital to be raised throughout 2025, but it “became increasingly selective over the course of the year,” Crux found.
Some $63 billion of tax credits changed hands — but again, there was a slowdown in the second half of the year due to uncertainty around how the OBBBA affected the market. Similarly, pricing for tax credits softened in the second half of the year, and deals got smaller.
Solar and storage “continued to represent a dominant share of current-year spot tax credit activity in 2025,” the Crux report says, making up just over half of the tax credit market. While solar on its own made up just over a third of the market, “storage-linked categories expanded most rapidly on a percentage basis, led by standalone storage, followed by solar and storage,” the team found.
Citing data from the U.S. Energy Information Administration showing that utility-scale storage deployment grew 72% over the course of 2025, from 11 gigawatts to 19 gigawatts, Johnson told me that storage is “categorically booming.”
“Storage was a major outlier and source of growth,” he said. “We continue as a country to provide a lot of support on top of a lot of demand for batteries, and that, in our view, is going to lead to a lot of continued deployment in the battery sector.”
But what about EVs? The large batteries in electric cars are a major source of demand that help catalyze the battery supply chain from the lithium and cobalt to the battery cells and packs. While the EV market may be getting hammered by inconsistent policy, battery manufacturing is still going strong, Johnson said, thanks to the demand for energy storage.
“There was a lot of pearl-clutching about what would happen to the battery supply chain with less policy support and EVs being less in favor,” he told me. “What you have seen is some number of those battery manufacturers have rotated their delivery and their product into grid-connected battery storage because that market has so much demand in it. So you’re still seeing a lot of that demand flow through into the need for capacity.”
Crux found that nearly a quarter of the Fortune 1000 companies are participating in the tax credit market. Their rising participation “drove the aggregate growth in the market and supported pricing despite rising market uncertainty following passage of the OBBB,” the report found.
When the market was just tax equity deals, in which investors partner directly with developers on a project in exchange for the value of the tax credits, it had only “a few dozen participants,” Johnson said. By 2023, a year after the Inflation Reduction Act allowed for those credits to be traded on third-party platform, it had around 50, he told me. Now that number is closer to 250.
“It’s becoming a more common part of the tax planning and cash management strategies that large companies are deploying,” Johnson said, pointing to data showing that tax credit buyers had effective tax rates three percentage points lower than non-buyers.
The Internal Revenue Service rolled out final rules for a new set of production and investment tax credits — the so-called tech neutral tax credits that applied to “any clean energy facility that achieves net-zero greenhouse gas emissions,” not just specific technologies chosen by Congress — in early 2025, just before the Biden administration left office.
Since then, these credits “have entered a choppy market,” the Crux report says.
“Crux’s survey of tax equity sponsors shows that most have limited investment in projects claiming the tech-neutral … credits,” which it attributed to concerns around stringent source requirements companies related to so-called foreign entities of concern must meet to claim these newer credits compared to the legacy investment and production tax credits.
Crux found modest but still measurable discounts for the tech-neutral tax credits compared to their predecessors of about 1 to 2 cents on the dollar for newer projects. (Projects that started construction before the end of 2024 were still eligible for the legacy credits.)
When talking to tax equity investors, Crux found that just 10%“reported actively pursuing tech-neutral tax credits,” while 90% said they would “only look at these credits under certain circumstances.”
“It’s mostly a comfort thing,” Johnson said. That may yet abate — he pointed out that “you saw preference in the early market for wind and solar credits versus advanced manufacturing and fuels and nuclear,” as new credits were developed, but eventually the market became more comfortable with funding new technologies and working with new credits, Johnson said.
“The new guidance that came out from the department on FEOC answers some of those questions,” Johnson said. “We think that that will drive some amount of additional market volume.”
The Supreme Court agreed to hear Suncor Energy Inc. v. County Commissioners of Boulder County, which concerns jurisdiction for “public nuisance” claims.
A new Supreme Court case will test whether the Trump administration’s war on federal climate regulation also undercuts fossil fuel companies’ primary defense against climate-related lawsuits.
On Monday, the court agreed to weigh in on whether Boulder, Colorado’s climate change lawsuit against major oil companies is preempted by federal law. Now that the federal government has revoked its own authority to regulate greenhouse gases, the justices will have to consider whether there even is any relevant federal law to speak of.
The case is arriving at the nation’s highest court in a particularly fraught moment for climate regulation. The Supreme Court ruled back in 2007 that the EPA had authority to regulate greenhouse gases under the Clean Air Act, preventing states from creating a patchwork of their own emissions rules. The decision also shielded energy companies from federal common law “public nuisance” claims — lawsuits seeking damages for climate change caused by greenhouse gas emissions.
Earlier this month, however, Trump’s EPA essentially challenged that Court decision. It made an official determination that the Clean Air Act did not, in fact, allow it to regulate emissions that have such diffuse, global effects.
“By revoking their authority on this issue, EPA, in our view, is basically eliminating what otherwise would have been a protection for companies against these kinds of lawsuits,” Andres Restrepo, a senior attorney at the Sierra Club, told me. “That really opens them up to a lot of potential legal liability and creates a lot of uncertainty.”
The new Supreme Court case dates back to 2018, when the city and county of Boulder, Colorado sued multinational oil giant ExxonMobil and Suncor, which operates the largest refinery in the state, for damages from climate change, bringing the charges under Colorado law. The oil companies tried repeatedly to get the case dismissed, arguing that it belonged in federal court. But time and again, the courts disagreed.
The Supreme Court already rejected an earlier petition to review the question of whether the case belonged in state or federal court in 2023. Now it has agreed to consider a slightly different petition, filed last summer, over whether federal law preempts Boulder’s state-law claims.
The Trump administration was acutely aware that its deregulatory moves had the potential to kick up a hornet’s nest of challenges for fossil fuel companies, so it tried to get ahead of the issue. In revoking the endangerment finding, the EPA claimed that while it “lacks statutory authority to regulate GHG emissions in response to global climate change concerns,” this has no impact on state preemption under the Clean Air Act. The agency’s final rule cites a section of that law about motor vehicle emission and fuel standards which says that states cannot adopt rules “relating to the control of emissions from new motor vehicles or new motor vehicle engines subject to this part.” In the agency’s view, this section applies broadly to any type of emission from a vehicle, whether or not the agency itself is tasked with regulating it.
The EPA also asserted that the Clean Air Act continues to preempt public nuisance claims, arguing that the Supreme Court did not base its dismissal of such claims on the EPA actually exercising any regulatory authority. The logic gets very circular here. Preemption “is no less applicable where, as here, the EPA does not regulate because Congress has not authorized such regulation as within the scope of its legal standard for determining what air pollution is dangerous and subject to regulation,” the agency wrote in its response to public comments on its initial proposal on this issue, which it published last summer.
“It feels like a bad ex-boyfriend who says, I don’t want to date you anymore, but you can’t date those other people either,” Vicki Arroyo, a law professor at Georgetown University and former Biden administration EPA official, told me.
Before the EPA finalized its decision on the endangerment finding, industry players were skittish about the legal implications. The Edison Electric Institute, the largest trade group for electric utilities, has not responded publicly to the final endangerment finding determination. It did, however, flag legal concerns in comments on the proposed rule last September, implicitly disagreeing with the EPA’s assertion that preemption was safe. It noted that the EPA’s actions could cast doubt on whether greenhouse gas emissions “remain a regulated pollutant under the Clean Air Act” in the power sector. That, in turn, could increase the likelihood that the power sector will be “further exposed to competing and conflicting regulations through a patchwork of state regulations” in addition to “the potential for increased litigation alleging common-law claims,” such as causing a public nuisance.
Automakers have also been virtually silent on the EPA’s actions. The Alliance for Automotive Innovation, the largest trade association for vehicle manufacturers, has not issued a statement on the matter. In its comments on the proposed rule, the group neither welcomed nor condemned the move. Unlike the power industry group, the automakers eagerly agreed with the EPA that rescinding the endangerment finding would not change federal preemption of state rules. It did warn, however, that eliminating greenhouse gas regulations altogether would subject the industry to yet another “rapid and dramatic” swing in policy that “puts billions of dollars of capital investment at risk.”
The only industry group I’ve seen come out firmly against the EPA’s final rule is the Zero Emissions Transportation Association, whose membership includes both automakers such as Rivian and utilities such as Duke Energy. Albert Gore, ZETA’s executive director, said in a statement that rescinding the endangerment finding “pulls the rug out from companies that have invested in manufacturing next-gen vehicles across the United States.” He also warned that it “opens businesses up to unnecessary legal risk,” including “a complicated patchwork of state regulations, threats of costly tort litigation, and inconsistent rules between markets.”
Ken Alex, a former senior assistant attorney general of California, was unequivocal that the EPA’s decision would open new avenues for public nuisance climate lawsuits. These suits are based on a complicated area of law known as federal common law, which permits courts to craft rules in very limited situations that have not been addressed by Congress. Alex represented California in the seminal 2011 Supreme Court case American Electric Power v. Connecticut, which established companies’ protection from federal public nuisance claims over greenhouse gas emissions. That decision sprang from the Court’s earlier 2007 decision that the Clean Air Act covers greenhouse gas emissions — which the EPA is now contesting.
The Boulder case will test how the Court views the EPA’s policy reversal long before legal challenges to the Trump administration get a hearing. SCOTUSblog reports that the Supreme Court is likely to hear oral arguments in the case, known as Suncor Energy Inc. v. County Commissioners of Boulder County, as soon as this fall. While the Boulder case contains similar public nuisance allegations to the American Electric Power case, Boulder brought them under state law, which means the legal questions and implications will be slightly different.
As for the possibility of a “patchwork of state regulations,” that’s a long ways away, if it is even possible at all, Alex said.
If the Supreme Court agrees with the EPA that the Clean Air Act does not apply to greenhouse gases, then there’s an argument that states are not precluded from acting, he told me. But there’s a counter-argument that any state action to regulate tailpipe greenhouse gas emissions will necessarily impact tailpipe emissions of other pollutants, bleeding into areas where Congress has explicitly preempted states from operating. “That’s also a good argument,” Alex said. “So it’s not clear to me how that would come out.”
Regardless, if the EPA’s final rule makes it through the highest court — which, to be sure, is not a foregone conclusion — Alex had no question that states would try to act. They will still have to meet the Clean Air Act’s general limits on air pollution, and California, for instance, “cannot meet those requirements without mobile source control,” he said. “They’ve got no choice but to seek regulations.”
