California’s Clean Air Act waiver may not be long for this world.
Nobody quite knows where Donald Trump stands on electric vehicles these days. While he’s reportedly coming for the $7,500 consumer EV tax credit and previously characterized the switch to EVs as a “transition to hell,” once Elon Musk threw his support behind Trump, the once and future president’s rhetoric has softened. But if past is prologue, Trump’s policies could still hammer one of Tesla’s primary income sources: the emissions compliance credits the EV giant sells to other automakers.
That windfall comes from California’s Zero-Emission Vehicle Program, which sets ambitious ZEV production and sales mandates that other states can then voluntarily adopt. Automakers earn credits based on the number and type of ZEVs they produce; they can either put those credits toward meeting their annual targets under the law or, if they have an excess, sell them. Since Tesla is a pure-play EV company, it has always generated more credits than it needs, while most other automakers need to buy credits to meet their emissions targets. Last year, selling credits represented about 12% of Tesla’s net income, and so far this year, it comprises a whopping 43%.
Underpinning this whole regime is California’s Clean Air Act waiver, granted by the Environmental Protection Agency, which allows the state to set stricter vehicle emissions standards than those at the federal level due to the “compelling and extraordinary circumstances” it faces when it comes to air quality. During his first term, Trump sought to rescind portions of this waiver related to greenhouse gas emissions and the ZEV mandate, and his campaign stated that he will do so again. While the federal government’s comparably weaker emissions standards ensure that the credit market won’t disappear completely, eliminating the waiver would cause it — and Tesla — to take a major hit.
“Given that Tesla has no new major high-volume product that they’ve announced, not having access to these credits is only going to be harmful,” Corey Cantor, an EV analyst at BloombergNEF, told me.
Tesla understands this — or at least it used to. The company strongly opposed the first Trump administration’s efforts to decrease penalties for automakers that fell short of federal fuel economy standards. “Tesla was in there in all those lawsuits arguing that the Trump administration was wrong and the penalty should be increased,” Ann Carlson, a professor of environmental law at UCLA, told me. As she explained, this is “evidence of how important that market is to them.” The higher the emissions penalties, the more automakers will rely on credits to avoid them.
Right now, California’s emissions targets are quite ambitious, and they’re poised to get even more so over the next decade, which would cause the credit market to heat up, too. With the introduction of California’s Advanced Clean Cars II program, 35% of all 2026 models sold must be ZEVs. These new vehicles, which include passenger cars, trucks, and SUVs, will start hitting production lines next year. The targets ramp up quickly from there — 68% of 2030 models must be ZEVs, while a full 100% of 2035 models must be zero-emissions. Besides California, 11 other states, plus Washington D.C. have signed onto these regulations.
Under Trump, all of these goals are likely gone — though it’s probable that they wouldn’t have been met anyway. Based on total retail sales so far this year, no states are selling a large enough percent of EVs and hybrids to comply with California’s forthcoming standards — not even California itself, which CNBC reports is sitting at 27% EV and plug-in hybrid sales. Toyota came out and called these standards impossible to meet, but there’s no indication that California is backing down.
The first time a Trump administration rescinded the state’s waiver, a number of automakers, including BMW of North America, Ford, Honda, Volkswagen Group of America, and Volvo agreed to abide by California’s original standards anyway, in exchange for an extra year to meet emissions targets and increased flexibility overall. The waiver ordeal ultimately got tied up in courts, and California’s regulations ended up being inactive for just two-and-a-half years, until Biden reinstated the waiver in 2022. Litigation is still ongoing, however, with a suit from an Ohio-led coalition of red states expected to end up in the Supreme Court.
Carlson told me we should know whether the court decides to accept this case in the next few months. At the heart of the argument is a question about whether California’s “compelling and extraordinary circumstances” extend to limiting climate change-causing greenhouse gas emissions and not just smog-causing air pollutants such as nitrogen oxides or particulate matter.
“All states are affected by climate. [California]’s not unique in the way that it had unique air pollution problems,” Carlson told me, explaining the argument Trump and red state allies will likely make. “California is going to retort by saying, We have very compelling and extraordinary circumstances. We have drought, we have higher temperatures, our ozone pollution is going up. We have wildfires, we have water supply issues.”
While we know that the conservative Supreme Court is relatively hostile to aggressive greenhouse gas regulation, which side of the debate Tesla winds up on is anyone’s guess. Now that Musk is within Trump’s inner circle, he apparently has a number of personal business interests that he’d like to pursue. These include federal funding for SpaceX and Starlink, but perhaps most importantly regulations around Tesla’s autonomous driving system, which he views as the future of the company. Despite findings that these systems have caused hundreds of crashes and a number of fatalities, Musk said on an October earnings call that he is seeking a federal approvals process for autonomous vehicles. This could expedite the current system, which requires lengthy applications for every state.
Cantor thinks it’s possible that Musk might be making strategic decisions about what fights to pick. “I wonder if there’s been so much focus on the autonomous vehicle regulations at the national level that it’s like, EV stuff be damned, I don’t really care, as long as I get my national AV authorization.“
After all, Tesla isn’t kicking up a fuss about Trump’s plan to go after the consumer EV tax credit, which Musk seems to think would cement the company’s dominant market position, on the assumption that less-experienced-makers will suffer more from the subsidy’s repeal. While looser emissions standards for Tesla’s competitors and reduced income from compliance credits seem like more of a clear-cut loss for Musk, perhaps it’s a hit he’s willing to take in pursuit of his broader goals.
At any rate, Carlson told me that an enduring rollback of California’s waiver will depend on competent administrators that are familiar with the complexity of the legislative process — not something Trump appointees are exactly known for. “The one thing that I can’t quite wrap my mind around is what the effect of Lee Zeldin combined with Project 2025 means,” Carlson said. Zeldin, Trump’s pick to lead the EPA, has no experience running a government agency and little expertise in environmental policy.
“The effect of an inexperienced administrator, combined with potentially freezing out or even firing some of the most competent and skilled economists, scientists, etc, could totally undermine the ability to do this in a way that is legally sustainable and fast,” Carlson told me.
If you squint hard enough, maybe that’s the silver lining, here.

“We had enough assurance that the president was going to deal with them.”
A member of the House Freedom Caucus said Wednesday that he voted to advance President Trump’s “big, beautiful bill” after receiving assurances that Trump would “deal” with the Inflation Reduction Act’s clean energy tax credits – raising the specter that Trump could try to go further than the megabill to stop usage of the credits.
Representative Ralph Norman, a Republican of North Carolina, said that while IRA tax credits were once a sticking point for him, after meeting with Trump “we had enough assurance that the president was going to deal with them in his own way,” he told Eric Garcia, the Washington bureau chief of The Independent. Norman specifically cited tax credits for wind and solar energy projects, which the Senate version would phase out more slowly than House Republicans had wanted.
It’s not entirely clear what the president could do to unilaterally “deal with” tax credits already codified into law. Norman declined to answer direct questions from reporters about whether GOP holdouts like himself were seeking an executive order on the matter. But another Republican holdout on the bill, Representative Chip Roy of Texas, told reporters Wednesday that his vote was also conditional on blocking IRA “subsidies.”
“If the subsidies will flow, we’re not gonna be able to get there. If the subsidies are not gonna flow, then there might be a path," he said, according to Jake Sherman of Punchbowl News.
As of publication, Roy has still not voted on the rule that would allow the bill to proceed to the floor — one of only eight Republicans yet to formally weigh in. House Speaker Mike Johnson says he’ll, “keep the vote open for as long as it takes,” as President Trump aims to sign the giant tax package by the July 4th holiday. Norman voted to let the bill proceed to debate, and will reportedly now vote yes on it too.
Earlier Wednesday, Norman said he was “getting a handle on” whether his various misgivings could be handled by Trump via executive orders or through promises of future legislation. According to CNN, the congressman later said, “We got clarification on what’s going to be enforced. We got clarification on how the IRAs were going to be dealt with. We got clarification on the tax cuts — and still we’ll be meeting tomorrow on the specifics of it.”
Neither Norman nor Roy’s press offices responded to a request for comment.
The foreign entities of concern rules in the One Big Beautiful Bill would place gigantic new burdens on developers.
Trump campaigned on cutting red tape for energy development. At the start of his second term, he signed an executive order titled, “Unleashing Prosperity Through Deregulation,” promising to kill 10 regulations for each new one he enacted.
The order deems federal regulations an “ever-expanding morass” that “imposes massive costs on the lives of millions of Americans, creates a substantial restraint on our economic growth and ability to build and innovate, and hampers our global competitiveness.” It goes on to say that these regulations “are often difficult for the average person or business to understand,” that they are so complicated that they ultimately increase the cost of compliance, as well as the risks of non-compliance.
Reading this now, the passage echoes the comments I’ve heard from industry groups and tax law experts describing the incredibly complex foreign entities of concern rules that Congress — with the full-throated backing of the Trump administration — is about to impose on clean energy projects and manufacturers. Under the One Big Beautiful Bill Act, wind and solar, as well as utility-scale energy storage, geothermal, nuclear, and all kinds of manufacturing projects will have to abide by restrictions on their Chinese material inputs and contractual or financial ties with Chinese entities in order to qualify for tax credits.
“Foreign entity of concern” is a U.S. government term referring to entities that are “owned by, controlled by, or subject to the jurisdiction or direction of” any of four countries — Russia, Iran, North Korea, and most importantly for clean energy technology, China.
Trump’s tax bill requires companies to meet increasingly strict limits on the amount of material from China they use in their projects and products. A battery factory starting production next year, for example, would have to ensure that 60% of the value of the materials that make up its products have no connection to China. By 2030, the threshold would rise to 85%. The bill lays out similar benchmarks and timelines for clean electricity projects, as well as other kinds of manufacturing.
But how companies should calculate these percentages is not self-evident. The bill also forbids companies from collecting the tax credits if they have business relationships with “specified foreign entities” or “foreign-influenced entities,” terms with complicated definitions that will likely require guidance from the Treasury for companies to be sure they pass the test.
Regulatory uncertainty could stifle development until further guidance is released, but how long that takes will depend on if and when the Trump administration prioritizes getting it done. The One Big Beautiful Bill Act contains a lot of other new tax-related provisions that were central to the Trump campaign, including a tax exemption for tips, which are likely much higher on the department’s to-do list.
Tax credit implementation was a top priority for the Biden administration, and even with much higher staffing levels than the department currently has, it took the Treasury 18 months to publish initial guidance on foreign entities of concern rules for the Inflation Reduction Act’s electric vehicle tax credit. “These things are so unbelievably complicated,” Rachel McCleery, a former senior advisor at the Treasury under Biden, told me.
McCleery questioned whether larger, publicly-owned companies would be able to proceed with major investments in things like battery manufacturing plants until that guidance is out. She gave the example of a company planning to pump out 100,000 batteries per year and claim the per-kilowatt-hour advanced manufacturing tax credit. “That’s going to look like a pretty big number in claims, so you have to be able to confidently and assuredly tell your shareholder, Yep, we’re good, we qualify, and that requires a certification” by a tax counsel, she said. To McCleery, there’s an open question as to whether any tax counsel “would even provide a tax opinion for publicly-traded companies to claim credits of this size without guidance.”
John Cornwell, the director of policy at the Good Energy Collective, which conducts research and advocacy for nuclear power, echoed McCleery’s concerns. “Without very clear guidelines from the Treasury and IRS, until those guidelines are in place, that is going to restrict financing and investment,” Cornwell told me.
Understanding what the law requires will be the first challenge. But following it will involve tracking down supply chain data that may not exist, finding alternative suppliers that may not be able to fill the demand, and establishing extensive documentation of the origins of components sourced through webs of suppliers, sub-suppliers, and materials processors.
The Good Energy Collective put out an issue brief this week describing the myriad hurdles nuclear developers will face in trying to adhere to the tax credit rules. Nuclear plants contain thousands of components, and documenting the origin of everything from “steam generators to smaller items like specialized fasteners, gaskets, and electronic components will introduce substantial and costly administrative burdens,” it says. Additionally the critical minerals used in nuclear projects “often pass through multiple processing stages across different countries before final assembly,” and there are no established industry standards for supply chain documentation.
Beyond the documentation headache, even just finding the materials could be an issue. China dominates the market for specialized nuclear-grade materials manufacturing and precision component fabrication, the report says, and alternative suppliers are likely to charge premiums. Establishing new supply chains will take years, but Trump’s bill will begin enforcing the sourcing rules in 2026. The rules will prove even more difficult for companies trying to build first-of-a-kind advanced nuclear projects, as those rely on more highly specialized supply chains dominated by China.
These challenges may be surmountable, but that will depend, again, on what the Treasury decides, and when. The Department’s guidance could limit the types of components companies have to account for and simplify the documentation process, or it could not. But while companies wait for certainty, they may also be racking up interest. “The longer there are delays, that can have a substantial risk of project success,” Cornwell said.
And companies don’t have forever. Each of the credits comes with a phase-out schedule. Wind manufacturers can only claim the credits until 2028. Other manufacturers have until 2030. Credits for clean power projects will start to phase down in 2034. “Given the fact that a lot of these credits start lapsing in the next few years, there’s a very good chance that, because guidance has not yet come out, you’re actually looking at a much smaller time frame than than what is listed in the bill,” Skip Estes, the government affairs director for Securing America’s Energy Future, or SAFE, told me.
Another issue SAFE has raised is that the way these rules are set up, the foreign sourcing requirements will get more expensive and difficult to comply with as the value of the tax credits goes down. “Our concern is that that’s going to encourage companies to forego the credit altogether and just continue buying from the lowest common denominator, which is typically a Chinese state-owned or -influenced monopoly,” Estes said.
McCleery had another prediction — the regulations will be so burdensome that companies will simply set up shop elsewhere. “I think every industry will certainly be rethinking their future U.S. investments, right? They’ll go overseas, they’ll go to Canada, which dumped a ton of carrots and sticks into industry after we passed the IRA,” she said.
“The irony is that Republicans have historically been the party of deregulation, creating business friendly environments. This is completely opposite, right?”

The Senate finally passed its version of Trump’s One Big Beautiful Bill Act Tuesday morning, sending the tax package back to the House in hopes of delivering it to Trump by the July 4 holiday. The excise tax on renewables that had been stuffed into the bill over the weekend was removed after Senator Lisa Murkowski of Alaska struck a deal with the Senate leadership designed to secure her vote. In her piece examining exactly what’s in the bill, Heatmap’s Emily Pontecorvo explains that even without the excise tax, the bill would “gum up the works for clean energy projects across the spectrum due to new phase-out schedules for tax credits and fast-approaching deadlines to meet complex foreign sourcing rules.” Debate on the legislation begins on the House floor today. House Speaker Mike Johnson has said he doesn’t like the legislation, and a handful of other Republicans have already signaled they won’t vote for it.
The Environmental Protection Agency this week sent the White House a proposal that is expected to severely weaken the federal government’s ability to rein in planet-warming pollution. Details of the proposal, titled “Greenhouse Gas Endangerment Finding and Motor Vehicle Reconsideration,” aren’t clear yet, but EPA Administrator Lee Zeldin has reportedly been urging the Trump administration to repeal the 2009 “endangerment finding,” which explicitly identified greenhouse gases as a public health threat and gave the EPA the authority to regulate them. Striking down that finding would “free EPA from the legal obligation to regulate climate pollution from most sources, including power plants, cars and trucks, and virtually any other source,” wrote Alex Guillén at Politico. The title of the proposal suggests it aims to roll back EPA tailpipe emissions standards, as well.

So long, MethaneSAT, we hardly knew ye. The Environmental Defense Fund said Tuesday that it had lost contact with its $88 million methane-detecting satellite, and that the spacecraft was “likely not recoverable.” The team is still trying to figure out exactly what happened. MethaneSAT launched into orbit last March and was collecting data about methane pollution from global fossil fuel infrastructure. “Thanks to MethaneSAT, we have gained critical insight about the distribution and volume of methane being released from oil and gas production areas,” EDF said. “We have also developed an unprecedented capability to interpret the measurements from space and translate them into volumes of methane released. This capacity will be valuable to other missions.“ The good news is that MethaneSAT was far from the only methane-tracking satellite in orbit.
Nvidia is backing a D.C.-based startup called Emerald AI that “enables AI data centers to flexibly adjust their power consumption from the electricity grid on demand.” Its goal is to make the grid more reliable while still meeting the growing energy demands of AI computing. The startup emerged from stealth this week with a $24.5 million seed round led by Radical Ventures and including funding from Nvidia. Emerald AI’s platform “acts as a smart mediator between the grid and a data center,” Nvidia explains. A field test of the software during a grid stress event in Phoenix, Arizona, demonstrated a 25% reduction in the energy consumption of AI workloads over three hours. “Renewable energy, which is intermittent and variable, is easier to add to a grid if that grid has lots of shock absorbers that can shift with changes in power supply,” said Ayse Coskun, Emerald AI’s chief scientist and a professor at Boston University. “Data centers can become some of those shock absorbers.”
In case you missed it: California Governor Gavin Newsom on Monday rolled back the state’s landmark Environmental Quality Act. The law, which had been in place since 1970, required environmental reviews for construction projects and had become a target for those looking to alleviate the state’s housing crisis. The change “means most urban developers will no longer have to study, predict, and mitigate the ways that new housing might affect local traffic, air pollution, flora and fauna, noise levels, groundwater quality, and objects of historic or archeological significance,” explainedCal Matters. On the other hand, it could also mean that much-needed housing projects get approved more quickly.
Tesla is expected to report its Q2 deliveries today, and analysts are projecting a year-over-year drop somewhere from 11% to 13%.
