There are two kinds of people who work on climate solutions: Those who still believe in the promise of carbon markets, and those who think the whole concept is fundamentally flawed.
In the first category, you have people like McGee Young, the CEO of a company called WattCarbon. Young is aware of the ways carbon markets can be a race to the bottom — enabling companies to buy cheap certificates that say they used clean energy or reduced their carbon footprint, when in reality their purchase had little effect on the environment or the energy system.
And yet, there’s all this money out there for the taking! Companies want to green their image! Tackling climate change is expensive! There must be a way to funnel corporate sustainability budgets to where they can make a real impact!
To Young, the solution is a matter of better data and greater transparency. “We need a record-keeping system that allows us to raise the bar,” he told me.
Young launched his vision for that record-keeping system on Wednesday — the WattCarbon Energy Attribute Tracking System, or WEATS. It functions similarly to other environmental credit registries: Owners of clean energy assets can sign up to generate credits known as Environmental Attribute Certificates, or EACs, which buyers can then purchase to count toward their own clean energy or carbon goals.
WEATS has two main features that differentiate it. First, it will include credits from small-scale distributed energy resources like residential solar panels, batteries, and heat pumps — clean energy solutions that haven’t really been able to participate in carbon markets until now. Second, each EAC will include granular information about where and when the power was generated, in the case of solar, or the carbon savings incurred, in the case of heat pumps, down to the hour.
The first feature is part of what motivated Young to start WattCarbon. “The clean energy transition is more than just wind and solar, it’s more than just generation,” he told me. But it’s the second that Young said is key to improving the credibility of claims that companies are “using 100% clean energy,” or “achieving net-zero.”
Today, many companies simply buy enough clean energy credits to match their annual energy use, regardless of where or when the energy was generated. But researchers have shown that this strategy can have little to no impact on emissions. For example, if a company is only buying solar credits, but it is using energy at night, its carbon footprint from that nighttime energy could surpass any environmental benefits of the solar it bought.
To solve this, some energy buyers have embraced a concept called “24/7 carbon-free energy,” which means that “every kilowatt-hour of electricity consumption is met with carbon-free electricity sources, every hour of every day, everywhere,” in the words of a United Nations-led initiative to promote the concept. “It is both the end state of a fully decarbonized electricity system,” according to the UN, “and a transformative approach to energy procurement, supply, and policy design that is critical to accelerating its arrival.”
If you’ve followed the recent debate about the green hydrogen tax credit, you might be familiar with the idea. In December, the Treasury Department proposed that hydrogen producers will have to match their electricity consumption with the purchase of local clean electricity generation on an hourly basis to prove their hydrogen is clean enough to qualify for the full value of the tax credit. That means producers can either hook up directly to a solar farm or wind farm or geothermal power plant and operate only when it is generating power, or, it can buy renewable energy credits or EACs that correspond to the hours that it operates.
WattCarbon’s marketplace is one of the first to enable this by requiring sellers to include data about exactly where and when each EAC was produced. It also include the carbon intensity of the grid in the place and time when that unit of power was produced. For example, 1 megawatt-hour of solar power in West Virginia, where the grid is supplied by a lot of coal-fired power plants, would likely reduce emissions far more than 1 megawatt-hour of solar power in California, where the main fossil fuel burned for power is natural gas. Similarly, 1 megawatt-hour of solar generated in the afternoon in California will not do as much to reduce emissions as if that unit of power were stored in a battery and then dispatched at night. On other markets, all of these credits might simply be advertised as 1 megawatt-hour of solar power, and the buyer would be none the wiser.
So what does this new carbon trading marketplace look like in practice? There are a lot of possibilities, but here’s one scenario. WattCarbon partners with a company that helps homeowners electrify their heating or install and manage their solar and battery systems. That third party company can then say to their customers, “As an extra incentive to do this, we can help you sell the environmental benefits it provides to third parties through the WattCarbon marketplace,” and those extra payments are what convinces the homeowner to go for it.
Independent experts I spoke with were cautiously optimistic about what this new marketplace could do. “We need to deploy on the order of a billion machines, in the U.S. alone — and not over a century, but on the order of a decade,” said Kevin Kircher, an assistant professor of mechanical engineering at Purdue University, whose research focuses on heat pumps and other distributed energy resources. “So there’s a lot that needs to be done, and just connecting people to money to do the work is really important.”
Wilson Ricks, a PhD candidate at Princeton University whose research informed the Treasury’s proposal for the hydrogen tax credit, said that having a platform where hydrogen companies can procure clean energy from a variety of projects, and with time and location data, would be very useful. He was also intrigued by WattCarbon’s attempt to create EACs tied to batteries because energy storage systems are one of the few resources that can produce clean power when the wind isn’t blowing and the sun isn’t shining.
But both Ricks and Kircher warned there are a number of ways this system of credits could fall into the same traps that ensnare many carbon offset projects and reduce their credibility. For one, it’s really hard to get the math right. That’s especially true for a project like a heat pump, where the carbon savings are based on a counterfactual situation where the homeowner would have kept their gas heater. You have to basically estimate how often they would have run it, which opens the door to sloppiness at best and fraud at worst.
Another key criterion — a concept called additionality — is very hard to assess. Would the household that switches to a heat pump have done so regardless of whether they were getting extra revenue from selling EACs? If the answer is unequivocally yes, the credits are meaningless and serve to give corporate emitters an excuse to keep emitting.
Young acknowledged to me that this was likely going to be true in some cases, but still felt that heat pump owners deserved to be paid for the environmental benefits they were providing. “We provide environmental subsidies for large-scale wind and solar, and we don't do that for the things that we're putting into our buildings and our communities. And to me, there’s an inherent inequality in the way that we treat and value clean energy that needs to be addressed.”
That didn’t quite make sense to me — the government provides subsidies for all kinds of clean energy resources, including distributed energy resources, I countered. The Treasury will give you $2,000 for a heat pump and a 30% discount on rooftop solar.
“That’s true,” Young said. “But we don’t have enough money in all of our government programs to truly scale those.”
I couldn’t argue with that. But the real challenge is helping low-income homeowners with the upfront capital to install these devices — after-the-fact payments are not enough. Young said he had plans to create a way for companies to procure EACs in advance from groups of homeowners. The deals would be similar to the power purchase agreements that big electricity consumers like Google and Walmart make with large-scale renewable energy developers, helping to finance those projects by reducing the risk.
“This is a necessary but not sufficient step,” Young said of the version of the marketplace that launched Wednesday. “Without this, we can’t do that. But this by itself would be inadequate for the market to be able to reach its fullest potential.”

A new “foreign entities of concern” proposal might be just as unworkable as the House version.
In the House’s version of Trump’s One, Big, Beautiful Bill Act Republicans proposed denying tax credits to clean energy companies whose supply chains contained any ties — big or small — to China. The rules were so administratively and logistically difficult, industry leaders said, that they were effectively the same as killing the tax credits altogether.
Now the Senate is out with a different proposal that, at least on its face, seems to be more flexible and easier to comply with. But upon deeper inspection, it may prove just as unworkable.
“It has the veneer of giving more specificity and clarity,” Kristina Costa, a Biden White House official who worked on Inflation Reduction Act implementation, told me. “But a lot of the fundamental issues that were present in the House bill remain.”
The provisions in question are known as the “foreign entities of concern” or FEOC rules. They penalize companies for having financial or material relationships with businesses 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.
The Inflation Reduction Act imposed FEOC restrictions on just one clean energy tax credit — the $7,500 consumer credit for electric vehicles. Starting in 2024, if automakers wanted their cars to qualify, they could not use battery components that were manufactured or assembled by a FEOC. The rules ratcheted up over time, later disallowing critical minerals extracted or processed by a FEOC.
The idea, Costa told me, was to “target the most economically important components and materials for our energy security and economic security.” But now, the GOP is attempting to impose FEOC restrictions liberally to every tax credit and every component, in a world where China is the biggest lithium producer and dominates roughly 80% of the solar supply chain.
Not only would sourcing outside China be challenging, it would also be an administrative nightmare. The way the House’s reconciliation bill was written, a single bolt or screw sourced from a Chinese company, or even a business partially owned by Chinese citizens, could disqualify an entire project. “How in the world are you going to trace five layers down to a subcontractor who’s buying a bolt and a screw?” John Ketchum, the CEO of the energy company NextEra, said at a recent Politico summit. Ketchum deemed the rules “unworkable.”
The Senate proposal would similarly attach FEOC rules to every tax credit, but it has a slightly different approach. Rather than a straight ban on Chinese sourcing, the bill would phase-in supply chain restrictions, requiring project developers and manufacturers to use fewer and fewer Chinese-sourced inputs over time. For example, starting next year, in order for a solar farm to qualify for tax credits, 40% of the value of the materials used to develop the project could not be tied to a FEOC. By 2030, the threshold would rise to 60%. The bill includes a schedule of benchmarks for each tax credit.
“That might be strict, but it’s clearer and more specific, and it’s potentially doable,” Derrick Flakoll, the senior policy associate for North America at BloombergNEF, told me. “It’s not an all or nothing test.”
But how companies should calculate this percentage is not self-evident. The Senate bill instructs the Treasury department to issue guidance for how companies should weigh the various sub-components that make up a project. It references guidance issued by the Biden administration for the purposes of qualifying for a domestic content bonus credit, and says companies can use this for the FEOC rules until new guidance is issued.
Mike Hall, the CEO of a company called Anza that provides supply chain data and analytics to solar developers, told me he felt that the schedule was achievable for solar farm developers. But the Biden-era guidance only contains instructions for wind, solar, and batteries. It’s unclear what a company building a geothermal project or seeking to claim the manufacturing tax credit would need to do.
Costa was skeptical that the Senate bill was, in fact, clearer or more specific than the House version. “They’re not providing the level of precision in their definitions that it would take to be confident that the effect of what they’re doing here will not still require going upstream to every nut, bolt, screw, and wire in a project,” she said.
It’s also hard to tell whether certain parts of the text are intentional or a drafting error. There’s a section that Flakoll had interpreted as a grandfathering clause to allow companies to exempt certain components from the calculation if they had pre-existing procurement contracts for those materials. But Costa said that even though that seems to have been the intent, the way that it’s written does not actually achieve that goal.
In addition to rules on sourcing, the Senate bill would introduce strict ownership rules that could potentially disqualify projects that are already under construction or factories that are already producing eligible components. The text contains a long list defining various relationships with Chinese entities that would disqualify a company from tax credits. Perhaps the simplest one is if a Chinese entity owns just 25% of the company.
BloombergNEF analyzed the pipeline of solar and battery factories that are operational, under construction, or have been announced in the U.S. as of March, and quite a few have links to China. The research firm identified 22 firms “headquartered in China with Chinese parent companies or majority-Chinese shareholders” that are behind more than 100 existing or planned solar or battery factories in the U.S.
One example is AESC, a Japanese battery manufacturer that sold a controlling stake in the business to a Chinese company in 2018. AESC has two gigafactories under construction in Kentucky and South Carolina, both of which are currently paused, and a third operating in Tennessee. Another is Illuminate USA, a joint venture between U.S. renewables developer Invenergy and Chinese solar panel manufacturer LONGi; it began producing solar panels at a new factory in Ohio last year. The sources I reached out to would not comment on whether they thought that Ford, which has a licensing deal with Chinese battery maker CATL, would be affected. Ford did not respond to a request for comment.
Hall told me he would expect to see Chinese companies try to divest from these projects. But even then, if the business is still using Chinese intellectual property, it may not qualify. “It’s just a lot of hurdles for some of these factories that are already in flight to clear,” he said.
In general, the FEOC language in the Senate bill was “still not good,” he said, but “a big improvement from what was in the House language, which just seemed like an insurmountable challenge.”
Albert Gore, the executive director of the Zero Emissions Transportation Association, had a similar assessment. “Of course, the House bill isn’t the only benchmark,” he told me. “Current law is, in my view, the current benchmark, and this is going to have a pretty negative impact on our industry.”
A statement from the League of Conservation Voters’ Vice President of Federal Policy Matthew Davis was more grave, warning that the Trump administration could use the ambiguity in the bill to block projects and revoke credits. “The FEOC language remains a convoluted, barely workable maze that invites regulatory chaos, giving the Trump administration wide-open authority to worsen and weaponize the rules through agency guidance,” he wrote.
On storm damage, the Strait of Hormuz, and Volkswagen’s robotaxi
Current conditions: A dangerous heat dome is forming over central states today and will move progressively eastward over the next week • Wildfire warnings have been issued in London • Typhoon Wutip brought the worst flooding in a century to China’s southern province of Guangdong.
Hurricane Erick made landfall as a Category 3 storm on Mexico’s Pacific coast yesterday with maximum sustained winds around 125 mph. Damages are reported in Oaxaca and Guerrero. The storm is dissipating now, but it could drop up to 6 inches of rain in some parts of Mexico and trigger life-threatening flooding and mudslides, according to the National Hurricane Center. Erick is the earliest major hurricane to make landfall on Mexico's Pacific coast, and one of the fastest-intensifying storms on record: It strengthen from a tropical storm to a Category 4 storm in just 24 hours, a pattern of rapid intensification that is becoming more common as the Earth warms due to human-caused climate change. As meteorologist and hurricane expert Michael Lowry noted, Mexico’s Pacific coast was “previously unfamiliar with strong hurricanes” but has been battered by epic storms over the last two years. Acapulco is still recovering from Category 5 Hurricane Otis, which struck in late 2023.

An oil tanker collision near the Strait of Hormuz is raising environmental and security concerns. The accident in the Gulf of Oman involved the Adalynn and Front Eagle tankers. It caused a “small oil spill,” according to the Emirati government, but Greenpeace analyzed satellite images and said the oil plume stretches some six square miles from the collision site. “This is just one of many dangerous incidents to take place in the past years,” said Greenpeace campaigner Farah Al Hattab. The Strait of Hormuz is a choke point for oil shipments, with about one-third of the volume of crude exported by sea moving through that route. Oil prices have been on a roller coaster ride since Israel launched airstrikes against Iran on June 13. Ships in the region have been reporting more GPS navigation interference in recent days. “If the conflict continues, we expect these interferences to continue as well,” Jean-Charles Gordon, senior director of ship tracking at research firm Kpler, toldThe New York Times.
North Carolina lawmakers finalized a bill repealing a mandate that directs electric regulators to reduce their carbon dioxide emissions by 70% by 2030. The mandate was part of a landmark 2021 law aimed at dramatically reducing the state’s power plant emissions. While at least 17 other states have similar laws in place, just two – North Carolina and Virginia – are in the Southeast. The new bill’s supporters say that the interim emissions goal would require energy providers to switch to more expensive power sources and that the costs would be passed on to consumers in the form of higher power bills.
Confusingly, regulators would still be asked to work toward carbon neutrality by 2050, even while the short-term emissions goal might be nixed. “Not having any target, even an aspirational target, could mean that we don’t stay on track to get to our 2050 goal,” Democratic Sen. Julie Mayfield said. The bill now goes to Democratic Gov. Josh Stein’s desk. There’s a chance he might veto it, but “with over a dozen House and Senate Democrats voting for the final version, the chances that any Stein veto could be overridden are higher,” The Associated Pressreported.
The United Kingdom issued long-awaited environmental guidance that it will use to determine whether new oil and gas proposals should be approved. The guidance requires that developers estimate and include scope 3 emissions – or the downstream pollution from burning oil and gas – in their drilling applications. This “will ensure the full effects of fossil fuel extraction on the environment are recognized in consenting decisions,” the Department for Energy Security and Net Zero said. The government will consider these emissions, as well as other factors like “the potential economic impact” of a project and a company’s efforts to remove carbon dioxide when granting or denying approval. The guidance will help determine whether major new drilling projects from oil giants Shell and Equinor are approved for the North Sea.
Volkswagen Group unveiled its first fully autonomous production vehicle, the ID. Buzz AD. The electric robotaxis will target corporate customers and mobility services. They “come packed with everything that’s needed to operate them,” explained Iulian Dnistran at InsideEVs. “What makes this solution interesting compared to other ride-hailing platforms is that it enables anybody to start an Uber or Waymo rival without investing hundreds of millions of dollars in research, development, and certification.” The shuttles are slated for launch across Europe and the U.S. next year. Tesla recently announced that its first Robotaxis would hit the streets in Austin, Texas, sometime this month.

In a new peer-reviewed paper published in the journal Communications Earth & Environment, researchers conclude that offsetting the potential carbon emissions from reserves held by the world’s 200 largest fossil fuel companies would require planting new forests that are larger than the entire continent of North America.
The energy secretary's philosophy is all over the Senate mega-bill.
As the Senate Finance Committee worked on its version of the reconciliation bill that would, among things, overhaul the Inflation Reduction Act, there was much speculation among observers that there could be a carve out for sources of power like geothermal, hydropower, and nuclear, which provide steady generation and tend to be more popular among Republicans, along the lines of the slightly better treatment received by advanced nuclear in the House bill.
Instead, the Senate Finance Committee’s text didn’t carve out these “firm” sources of power, it carved out solar and wind, preserving tax credits for everything else through 2035, while sunsetting solar and wind by 2028.
For much of the last few months — and for years before he was sworn in as Secretary of Energy — Chris Wright has been expounding on his philosophy of energy and climate. If anything, the Senate Finance draft seems to hew closer to Wright’s worldview than Trump’s, which is less specific, even more critical of renewables (especially wind), and largely in favor of nuclear power when it comes to non-carbon-emitting generation.
“I’m sure Secretary Wright’s strong support for firm technologies over the past few months played a role in Chairman Crapo’s approach to energy tax credit reform,” Pavan Venkatakrishnan, an infrastructure fellow at the Institute for Progress, told me.
Wright argues that climate change is real but not a top-tier concern and that it certainly should not be addressed by restricting energy usage, which he sees as foundational to the good life here and abroad.
And among energy sources, the former fracking executive is no opponent of fossil fuels but is also enthusiastic about energy innovation.
In his company Liberty Energy’s Bettering Human Lives report, published last year, which doubles as a kind of manifesto, Wright wrote that “viable paths to reducing greenhouse gas (GHG) emissions can only come from reliable and affordable low-carbon energy technologies,” and specifically listed next-generation nuclear and geothermal, which Liberty had invested in through the geothermal company Fervo and nuclear company Oklo.
“To achieve largescale human betterment, we will need significant future energy additions from nuclear, hydropower, geothermal, and all other viable energy technologies,” the report read.
And he’s often been skeptical of renewables along the lines of many Congressional Republicans, that they aren’t reliable enough and require additional resources to fully support the grid.
“Maybe the biggest problem is intermittency,” Wright said at a Liberty Energy event last year.
“You can build a lot of wind and solar, and then at night, the sun’s not shining and then sometimes the wind doesn’t blow, and you have no energy. So to keep society running, you have to have a whole second separate energy system,” Wright said.
In testimony to the House of Representatives last week, Wright said “If you’re not there at peak demand, you’re just a parasite on the grid, because you just make the other sources turn up and down as you come and go.”
Many critics of the Republican reconciliation bills have noted that much of the electricity generation pipeline is solar, wind, or storage, and so cutting off their tax credits risks leaving the country at an energy shortage while gas turbines take years and years to actually get on the grid.
But as Congress was working on the reconciliation bill, Wright made a series of widely noted public appearances where he promoted clean firm power and continued government support for it.
“My recommendation has been to leave behind the equivalent of the wind and solar tax credits — through if you start construction by 2031 — for nuclear fission and fusion and geothermal,” Wright said at an event earlier this month.
In May, Wright addressed the Nuclear Energy Institute, outlining his support for sunsetting wind and solar tax credits will working to kickstart nuclear power. “My personal goal would be to much more rapidly sunset the technologies that have been around and have been living on decades of subsidies,” Wright said. He also supported a “window” of “favorable treatment” for nuclear and geothermal.
“I’m in favor of every nudge, every incentive we can get from the federal government to restart this industry,” Wright said.
While Wright has been skeptical of wind and solar and optimistic about nuclear and geothermal for years, he’s also started talking more positively about energy storage. In the past, he’s talked up hydrocarbons for “coming with their own storage,” as he put it in a 2018 podcast.
But at an appearance at ARPA-E in March, Wright gave some of his most extended thoughts on energy storage, which sits somewhat awkwardly between variable resources like solar and wind and firm resources like nuclear and geothermal.
“Solar is growing very fast, getting more efficient and taking panels, cheaper materials and developing energy,” Wright said. “The biggest problem there is the sun doesn’t always shine, and we don’t know when clouds are going to come and when it’s not going to shine, but if we can get energy storage better, that’s a game changer.”
At least until 2035.
