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, andSenateRepublicans 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.

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.
Heatmap Illustration/Getty Images
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.

Shares in Sunrun, SolarEdge, and Enphase are collapsing on the Senate’s new mega-bill draft.
The residential solar rescue never happened. Shares in several residential solar companies plummeted Tuesday as the market reacted to the Senate Finance Committee’s reconciliation language, which maintains the House bill’s restriction on investment tax credits for residential solar installers and its scrapping of the tax credit for homeowners who buy their own systems.
The Solar Energy Industries Association, a solar trade group, criticized the Senate text, saying that it had only “modest improvements on several provisions” and would “pull the plug on homegrown solar energy and decimate the American manufacturing renaissance.”
Sunrun shares fell 40% Tuesday, bringing the company’s market cap down by almost $900 million to $1.3 billion, a comparable loss in value to what it sustained the day after the passage of the House reconciliation bill. The stock price had jumped up late last week due to optimism that the Senate Finance bill might include friendlier language for its business model.
Instead the Finance Committee proposal would terminate the residential clean energy tax credit for any systems, including residential solar, six months after the bill is signed. The text also zeroes out investment and production tax credits for residential solar when “the taxpayer rents or leases such property to a third party,” a common arrangement in the industry pioneered by Sunrun.
Sunrun’s third party ownership model well predates the Inflation Reduction Act and is about as old as the company itself, which was founded in 2007. The company had been claiming investment tax credits for solar before the IRA made them tech neutral. The company began securitizing solar deals in 2015 and in a 2016 securities filling, the company said that it had six deals where investors would be able to garner the lease payments and investment tax credits.
“Ain’t no sunshine for resi,” Jefferies analyst Julien Dumoulin-Smith wrote in a note to clients on Tuesday. “Overall, we view Senate's version as a negative” for Sunrun, as well as SolarEdge and Enphase, the residential solar equipment companies, whose shares are down by about 33% and 24% respectively.
“If this language is not adjusted before the bill passes the Senate floor,” Morgan Stanley analyst Andrew Perocco wrote in a note to clients, “we believe Sunrun, SolarEdge, and Enphase will trade towards our bear cases.”
Morgan Stanley had earlier estimated that cutting off home solar from tax credits would lead to a “85% contraction in residential solar volumes” due, in many cases, to solar products no longer resulting in savings on electricity bills.
That’s because the ability to lease solar equipment (or have homeowners sign power purchase agreements) and then claim tax credits sits at the core of the contemporary residential solar model.
“Our core solar service offerings are provided through our lease and power purchase agreements,” the company said in its 2024 annual report. “While customers have the option to purchase a solar energy system outright from us, most of our customers choose to buy solar as a service from us through our Customer Agreements without the significant upfront investment of purchasing a solar energy system.”
This means that to claim tax credits for the projects, they have to be investment tax credits, not home energy credits. These credits play a role in Sunrun’s extensive business raising money from investors to finance solar projects, which can then be partially monetized via tax credits.
Fund investors “can receive attractive after-tax returns from our investment funds due to their ability to utilize Commercial ITCs,” the company said in its report. The financing then “enables us to offer attractive pricing to our customers for the energy generated by the solar energy system on their homes.”
Without the ability to claim investment tax credits, Sunrun could be left having to charge higher prices to homeowners and face a higher cost of capital to raise money from investors.
“Last night’s draft text confirms the Senate intends to abruptly repeal tax credits available to homeowners who want to go solar – effectively increasing costs and limiting choice for countless Americans,” Chris Hopper, chief executive of Aurora Solar, said in an emailed statement.
On the Senate Finance Committee’s budget proposal, the NRC, and fossil-fuel financing
Current conditions: A brush fire that prompted evacuations in Maui on Sunday and Monday is now 93% contained • The Des Moines metro area issued its first-ever ban on watering lawns due to record nitrate concentrations in nearby rivers • For only the fourth time since 1937, Vancouver, British Columbia got no rain at all in the first half of June. The dry streak may finally break tonight.
The Senate Finance Committee published its portion of the budget reconciliation bill on Monday night, including details of its highly anticipated plan to revise the nation’s clean energy tax credits. Though the Senate version slightly softens the House’s proposed phase out of tax credits, “the text would still slash many of the signature programs of the Inflation Reduction Act,” my colleagues Emily Pontecorvo and Robinson Meyer write in their breakdown of the bill. Other changes to be aware of include:
There’s more, too, which you can read here.
President Trump fired Chris Hanson, a Democrat and his first-term appointee to the U.S. Nuclear Regulatory Commission, on Friday. Trump “terminated my position … without cause, contrary to existing law and longstanding precedent regarding removal of independent agency appointees,” Hanson said in his announcement, published Monday. Since the creation of the NRC, which regulates nuclear power, no commissioner has ever been fired from the body.
After being appointed by Trump in 2020, Hanson was promoted to chair the commission by President Biden in 2021. His term ended in January, after which he returned to serving on the board, Notus reports. Trump’s decision to fire Hanson comes on the heels of his recent flurry of executive orders aimed at quadrupling U.S. nuclear capacity, including a measure seeking to “simplify and accelerate the NRC’s licensing procedure, giving the body 18 months to issue new rules and guidance designed to shorten the timeline for processing new applications to 18 months at the longest,” as my colleagues Matthew Zeitlin and Katie Brigham explained last month. News of Hanson’s firing was met with “serious dismay” by attendees of the American Nuclear Society conference underway in Chicago, per Katy Huff, an assistant professor at the University of Illinois at Urbana-Champaign. In a statement, ANS argued that a “competent, effective, and fully staffed [NRC] is essential to the rapid deployment of new reactors and advanced technologies.”
Banks increased fossil fuel financing by more than one-fifth in 2024, marking the first time that fossil fuel financing has failed to decline since 2021, a new report by the Rainforest Action Network and other environmental groups found. Among the world’s top 65 largest banks, coal, oil, and gas assets rose by $162 billion, to $869 billion, with JPMorgan Chase seeing the biggest increase of more than a third to $53.5 billion, followed by Citigroup, Bank of America, and Barclays. In a statement to the Financial Times, JPMorgan said it believed its own data “reflects our activities more comprehensively,” and said it provided $1.29 in clean-energy financing for every dollar financing fossil fuels. However, as the report argues, “Banks are abandoning their previously announced emissions reduction targets in favor of temperature trajectories that allow for more fossil fuel finance. Though they may also increase financing of renewable energy, banks’ continued fossil fuel finance entrenches climate chaos and undercuts clean energy development.” Read the full findings here.
Drivers in Europe are becoming more unwilling to consider switching to an electric vehicle, outpacing even the growing reluctance seen in the United States, according to a new survey published by Shell on Tuesday. In Europe, 41% of respondents said they’d consider switching to an EV, down from 48% last year, while in the U.S., the number fell only 3 percentage points, to 31%. “Europe surprised us,” David Bunch, Shell’s chief for mobility and convenience, said, per Reuters. “The single biggest barrier to entry is the cost of the vehicle.”
While Shell — the world’s second-biggest fossil fuel company by revenue and profit — might seem an unlikely source for an electric vehicle survey, the company also has the most extensive EV charging network in the UK. Its findings weren’t all negative, either: in China, interest in buying an electric vehicle was as high as 89%. Additionally, Shell found that nine in 10 EV drivers would consider purchasing an electric vehicle again, and 60% said they worry less about running out of charge than they did a year ago, Bloomberg reports. Separately, International Energy Agency data shows that electric vehicle adoption continues at a healthy pace worldwide, exceeding 17 million sales globally in 2024, or a share of more than 20%.

The United Kingdom on Tuesday announced its commitment of £7.9 billion, or more than $10 billion, to the nation’s most extensive flood defense infrastructure program in its history. The program will not only include traditional construction, such as flood barriers, but also nature-based solutions like reforestation and wetland restoration, according to Business Green. In its announcement, the government said that for every £1 invested, it expected to prevent £8 in economic damage. “Protecting citizens is the first duty of any government,” Environment Secretary Steve Reed said in a statement, adding, “As our changing climate continues to bring more extreme weather to the nation, it's never been more vital to invest in new flood defences and repair our existing assets.” Separately, the U.K. Treasury also announced Tuesday a plan to spend £1 billion, or about $1.3 billion, on “funding to repair bridges, tunnels, and flyovers that are facing increased impacts from extreme weather and heavier vehicles,” Business Green adds.
Republicans in Los Angeles who don’t have air conditioning are “more likely to consider climate change a human-caused threat and more likely to support individual and government action to address climate change” than Republicans who have central air, a recent study published by the American Meteorological Society found. There was no similar divide among Democrats.
Wind and solar are out. Clean, firm power is in.
The Senate Finance committee published its highly anticipated tax proposal for Trump’s One Big, Beautiful Bill on Monday night, including a new plan to revise the nation’s clean energy tax credits.
Senate Republicans widened the aperture slightly compared to the House version of the bill, extending tax credits for geothermal energy, batteries, and hydropower, and preserving “transferability” — a crucial rule that allows companies to sell their tax credits for cash — for years to come.
But the text would still slash many of the signature programs of the Inflation Reduction Act. It would be particularly damaging for Republicans’ goals of creating a domestic mining industry, because it kills incentives for refining critical minerals while yanking away subsidies for the electric cars and wind turbines that might use those minerals.
Consumer tax credits for energy efficiency upgrades, including heat pumps, would still be terminated, as would credits for homeowners to lease or purchase rooftop solar. The Senate bill also cuts a tax deduction for energy efficiency upgrades in commercial buildings one year after the bill’s passage, which was not in the House version.
There was no mercy for the IRA’s tax credit to produce clean hydrogen, despite a last-minute appeal from more than 250 organizations in early June. That policy would still be terminated this year.
Here’s a rundown of the rest of the major changes.
Like the House bill, the Senate’s proposal would terminate tax credits for new, used, and leased electric vehicles. But while the House had extended the program by one year for automakers that had yet to sell 200,000 eligible vehicles, the Senate version would simply end the program in 180 days — or roughly six months — after the bill’s passage.
Depending on when the bill is passed, the Senate version could work out better for some experienced EV automakers, such as Tesla and General Motors. These automakers are set to lose their eligibility for tax credits on December 31 under the House text. But the Senate bill’s 180-day period could allow them to eke out another month or so of eligibility — especially if congressional negotiations over the One Big, Beautiful Bill Act go late into the summer.
Newer EV automakers, such as Rivian or Lucid, come out worse under the Senate text as compared to the House bill since they haven’t sold as many vehicles.
Homeowners interested in electric vehicle chargers would get a longer runway than the House had proposed — but a much shorter one than is on the books right now. Under current law, homeowners can claim the charger tax credit through 2032. The Senate version would terminate the 30% tax credit for installing a home charger one year after the bill is enacted.
The Inflation Reduction Act achieved massive greenhouse gas reductions by including a set of new “technology-neutral” tax credits that subsidized any new power plant as long as it didn’t emit carbon dioxide. Under current law, these new tax credits will remain effective and on the books for decades to come — expiring only when emissions from the country’s power sector fall about 95% below their all-time high.
The Republican reconciliation bills have dismantled these provisions. The House text proposed immediately winding down tax credits for all clean energy sources — except nuclear — and allowed just a 60-day “grace period” for new projects to start construction to claim the credits. Even then, new power plants would have to enter service by 2028 to qualify.
Senate Republicans have countered with a plan that is designed to maintain support for every electricity source that isn’t wind and solar. The GOP Senate caucus favors technologies that can provide power on demand around the clock — such as geothermal, nuclear, hydropower, and batteries — but technically the Senate text allows any zero-carbon, non-solar, non-wind source to qualify for the clean electricity tax credits for the next decade.
The Senate draft erases the provision in the Inflation Reduction Act that would have kept these tax credits in place until the entire United States power sector reduces its emissions. Instead, it adopts the IRA’s alternate phase-out period, with the tax credits beginning to wind down for projects that start construction in 2034.
Tax credits for wind and solar, however, would begin to phase down for projects that start construction next year, and terminate after 2027, with one big exception.
An odd addendum to the wind and solar phase-out would exempt projects that are at least 1 gigawatt, are at least partially on federal land, and have already received a “right-of-way grant or lease” from the Bureau of Land Management as of June 16. It’s unclear which, if any, projects would be helped by this provision. According to the BLM website, it has not granted a right-of-way to any projects that are 1 gigawatt or larger except for the Lava Ridge wind farm, which has been canceled. If the Senate changes the date, however, the Esmeralda 7 solar farm in Nevada may benefit, as the project is more than 6 gigawatts, and is in the final stages of its environmental review.
The Senate text would not do anything to change the eligibility timeline for existing nuclear plants to claim a tax credit, called 45U, designed to keep them solvent. It would keep the schedule written into the Inflation Reduction Act, which has the credit terminating at the end of 2031. It would, however, impose new foreign sourcing restrictions on nuclear fuel, forbidding existing power plants from claiming the tax credit if their fuel comes from Russia, China, Iran, or North Korea. (It makes an exception for power companies that signed a long-term contract to buy foreign fuel before 2023.) The United States formally banned the import of nuclear fuel from Russia last year.
The Inflation Reduction Act subsidized the production of certain clean energy equipment — including solar panels, wind turbines, inverters, and batteries — as well as some of their subcomponents. Under current law, those tax credits will begin to phase out by 25% increments in 2030, so companies can claim 75% of the credit in 2030, 50% in 2031, and zero in 2033.
The IRA also created a new permanent tax credit that covered 10% of the cost of refining or recycling critical minerals.
The new Senate text changes these phase-out deadlines, often for the worse. First, as in the House bill, wind turbines and their subcomponents would no longer qualify for the tax credit starting in 2028. Second, the tax credit for critical minerals would start phasing out in 2031. Under the new calendar, companies would be able to claim 75% of this credit in 2031, 50% in 2032, and zero in 2034.
In practice, this means that the Senate GOP text would end the IRA’s permanent tax credit for producing many critical minerals, which would damage the financial projects of many mineral processing and refining projects. Other types of equipment remain on the Inflation Reduction Act’s original phase-out schedule.
The new Senate text also slightly expands the type of battery components that qualify for the credit. And — in a potentially significant change for some companies — it forbids companies from stacking tax credits for their vertically integrated production process starting in 2027.
While the House did not touch the tax credit for carbon sequestration, the Senate has put forward a key change favored by many proponents of the technology. Under current law, project operators get the highest-value credit if they simply inject captured carbon underground for no other purpose than to keep it out of the atmosphere. Smaller amounts are available for projects that use captured CO2 to nudge more oil out of the ground, also known as “enhanced oil recovery,” or if they use the CO2 in products like cement.
Under the Senate proposal, all carbon sequestration projects, no matter the nature of the carbon storage, would qualify for the same amount.
The biggest clean energy killer in the House-passed bill was a strict sourcing rule for the tax credits that would disqualify projects that use any component, subcomponent or mineral from China. As Heatmap’s Matthew Zeitlin wrote last week, the rules appeared “unworkable” to many companies because they seemingly disqualified projects even if they used a relatively small amount of an otherwise irrelevant Chinese-sourced material — such as a spare bolt or a gram of steel.
Under the House bill, manufacturers would also not be allowed to license a Chinese company’s technology. This measure appeared to directly target Ford, which has proposed manufacturing electric vehicle batteries using technology licensed from the Chinese firm CATL, one of the world’s best producers of EV batteries.
The Senate proposal changes the House provision by adding a complicated new set of definitions about what might qualify as a federal entity of concern. It also introduces a new “safe harbor” formula describing the amount of Chinese-sourced material that can keep a project from receiving a tax credit. We’re still figuring out how these new rules work together, and we’ll update this article as we understand them better.
The House bill also would have severely curtailed a crucial component of the tax credit program called transferability, which allowed developers that couldn’t take full advantage of the subsidies to sell their credits for cash to other companies. The text stripped this option from the tax credits for clean manufacturing (45X), carbon sequestration (45Q), and clean fuels (45Z) beginning in 2028. Without transferability, most carbon sequestration projects will struggle to pencil out, my colleague Katie Brigham reported.
The Senate proposal would restore transferability for the duration of all remaining tax credits.
But it throws another wrench in plans to scale up nuclear, geothermal, and other large capital-intensive projects, because it restricts zero-carbon power plants’ ability to use modified accelerated cost recovery to fund their projects.
The Inflation Reduction Act created a technology-neutral tax credit for low-carbon transportation fuels, like sustainable aviation fuel and biodiesel (45Z). This was the only tax credit that the House GOP had proposed extending, giving projects four more years to qualify. The House bill also said that producers did not have to account for indirect land-use changes as a result of turning crops into fuel — a provision that would enable the corn ethanol industry to claim the credit.
The Senate proposal retains both of those provisions, but reduces the credit amount by 20% for fuels produced from feedstocks sourced from outside the United States. It also introduces a new rule that would prohibit companies from claiming their fuel has a “negative emissions” rate — which some environmental groups warn would subsidize established technologies and distort the market. Proponents of several forms of biomethane have tried to claim they are net-negative because they prevent methane emissions that would have otherwise happened — like when methane is captured from landfills or manure pools.
Confusingly, though, the text makes an exception, allowing negative emissions rates for fuels made from manure — which is the feedstock environmental groups are most concerned about.
This article was updated on June 17 to include the breakdown of 45Z.
