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.”

Removing the subsidies would be bad enough, but the chaos it would cause in the market is way worse.
In their efforts to persuade Republicans in Congress not to throw wind and solar off a tax credit cliff, clean energy advocates have sometimes made what would appear to be a counterproductive argument: They’ve emphasized that renewables are cheap and easily obtainable.
Take this statement published by Advanced Energy United over the weekend: “By effectively removing tax credits for some of the most affordable and easy-to-build energy resources, Congress is all but guaranteeing that consumers will be burdened with paying more for a less reliable electric grid.”
If I were a fiscal hawk, a fossil fuel lobbyist, or even an average non-climate specialist, I’d take this as further evidence that renewables don’t need tax credits. The problem is that there’s a lot more nuance to the “cheapness” of renewables than snappy statements like this convey.
“Renewables are cheap and they’ve gotten cheaper, but that doesn’t mean they are always the cheapest thing, unsubsidized,” Robbie Orvis, the senior director of modeling and analysis at Energy Innovation, told me back in May at the start of the reconciliation process. Natural gas is still competitive with renewables in a lot of markets — either where it’s less windy or sunny, where natural gas is particularly cheap, or where there are transmission constraints, for example.
Just because natural gas plants might be cheaper to build in those places, however, doesn’t mean they will save customers money in the long run. Utilities pass fuel costs through to customers, and fuel costs can swing dramatically. That’s what happened in 2022 after Russia invaded Ukraine, Europe swore off Russian gas, and the U.S. rushed to fill the supply gap, spiking U.S. natural gas prices and contributing to the largest annual increase in residential electricity spending in decades. Winter storms can also reduce natural gas production, causing prices to shoot up. Wind and solar, of course, do not use conventional fuels. The biggest factor influencing the price of power from renewables is the up-front cost of building them.
That’s not the only benefit that’s not reflected in the price tags of these resources. The Biden administration and previous Congress supported tax credits for wind and solar to achieve the policy goal of reducing planet-warming emissions and pollution that endangers human health. But Orvis argued you don’t even need to talk about climate change or the environment to justify the tax credits.
“We’re not saying let’s go tomorrow to wind, water, and solar,” Orvis said. “We’re saying these bring a lot of benefitsonto the system, and so more of them delivers more of those benefits, and incentives are a good way to do that.” Another benefit Orvis mentioned is energy security — because again, wind and solar don’t rely on globally-traded fuels, which means they’re not subject to the actions of potentially adversarial governments.
Orvis’ colleague, Mike O’Boyle, also raised the point that fossil fuels receive subsidies, too, both inside and outside the tax code. There’s the “intangible drilling costs” deduction, allowing companies to deduct most costs associated with drilling, like labor and site preparation. Smaller producers can also take a “depletion deduction” as they draw down their oil or gas resources. Oil and gas developers also benefit from low royalty rates for drilling on public lands, and frequently evade responsibility to clean up abandoned wells. “I think in many ways, these incentives level the playing field,” O’Boyle said.
When I reached out to some of the clean energy trade groups trying to negotiate a better deal in Trump’s tax bill, many stressed that they were most worried about upending existing deals and were not, in fact, calling for wind and solar to be subsidized indefinitely. “The primary issue here is about the chaos this bill will cause by ripping away current policy overnight,” Abigail Ross Hopper, the CEO of the Solar Energy Industries Association, told me by text message.
The latest version of the bill, introduced late Friday night, would require projects to start construction by 2027 and come online by 2028 to get any credit at all. Projects would also be subject to convoluted foreign sourcing rules that will make them more difficult, if not impossible, to finance. Those that fail the foreign sourcing test would also be taxed.
Harry Godfrey, managing director for Advanced Energy United, emphasized the need for “an orderly phase-out on which businesses can follow through on sound investments that they’ve already made.” The group supports an amendment introduced by Senators Joni Ernst, Lisa Murkowski, and Chuck Grassley on Monday that would phase down the tax credit over the next two years and safe harbor any project that starts construction during that period to enable them to claim the credit regardless of when they begin operating.
“Without these changes, the bill as drafted will retroactively change tax policy on projects in active development and construction, stranding billions in private investment, killing tens of thousands of jobs, and shrinking the supply of new generation precisely when we need it the most,” Advanced Energy United posted on social media.
In the near term, wind and solar may not need tax credits to win over natural gas. Energy demand is rising rapidly, and natural gas turbines are in short supply. Wind and solar may get built simply because they can be deployed more quickly. But without the tax credits, whatever does get built is going to be more expensive, experts say. Trade groups and clean energy experts have also warned that upending the clean energy pipeline will mean ceding the race for AI and advanced manufacturing to China.
Godfrey compared the reconciliation bill’s rapid termination of tax credits to puncturing the hull of a ship making a cross-ocean voyage. You’ll either need a big fix, or a new ship, but “the delay will mean we’re not getting electrons on to the grid as quickly as we need, and the company that was counting on that first ship is left in dire straits, or worse.”
A new subsidy for metallurgical coal won’t help Trump’s energy dominance agenda, but it would help India and China.
Crammed into the Senate’s reconciliation bill alongside more attention-grabbing measures that could cripple the renewables industry in the U.S. is a new provision to amend the Inflation Reduction Act to support metallurgical coal, allowing producers to claim the advanced manufacturing tax credit through 2029. That extension alone could be worth up to $150 million a year for the “beautiful clean coal” industry (as President Trump likes to call it), according to one lobbyist following the bill.
Putting aside the perversity of using a tax credit from a climate change bill to support coal, the provision is a strange one. The Trump administration has made support for coal one of the centerpieces of its “energy dominance” strategy, ordering coal-fired power plants to stay open and issuing a raft of executive orders to bolster the industry. President Trump at one point even suggested that the elite law firms that have signed settlements with the White House over alleged political favoritism could take on coal clients pro bono.
But metallurgical coal is not used for electricity generation, it’s used for steel-making. Moreover, most of the metallurgical coal the U.S. produces gets exported overseas. In other words, cheaper metallurgical coal would do nothing for American energy dominance, but it would help other countries pump up their production of steel, which would then compete with American producers.
The new provision “has American taxpayers pay to send metallurgical coal to China so they can make more dirty steel and dump it on the global market,” Jane Flegal, the former senior director for industrial emissions in the Biden White House, told me.
The U.S. produced 67 million short tons of metallurgical coal in 2023, according to data from the U.S. Energy Information Administration, more than three-quarters of which was shipped abroad. Looking at more recent EIA data, the U.S. exported 57 million tons of metallurgical coal through the first nine months of 2024. The largest recipient was India, the final destination for over 10 million short tons of U.S. metallurgical coal, with almost 9 million going to China. Almost 7 million short tons were exported to Brazil, and over 5 million to the Netherlands.
“Metallurgical coal accounts for approximately 10% of U.S. coal output, and nearly all of it is exported. Thermal coal produced in the United States, by contrast, mostly is consumed domestically,”according to the EIA.
The tax credit comes at a trying time for the metallurgical coal sector. After export prices spiked at $344 per short ton in the second quarter of 2022 following Russia’s invasion of Ukraine (much of Ukraine’s metallurgical coal production occurs in one of its most hotly contested regions), prices fell to $145 at the end of 2024, according to EIA data.
In their most recent quarterly reports, a number of major metallurgical coal producers told investors they wanted to reduce costs “as the industry awaits a reversal of the currently weak metallurgical coal market,” according to S&P Global Commodities Insights, citing low global demand for steel and economic uncertainty.
There was “not a whisper” of the provision before the Senate’s bill was released, according to the lobbyist, who was not authorized to speak publicly. “No one had any inkling this was coming,” they told me.
But it’s been a pleasant surprise to the metallurgical coal industry and its investors.
Alabama-based Warrior Met Coal, which exports nearly all the coal it produces, reported a loss in the first quarter of 2025,blaming “the combination of broad economic uncertainty around global trade, seasonal demand weakness, and ample spot supply is expected to result in continued pressure on steelmaking coal prices.” Its shares were up almost 6% in afternoon trading Monday.
Tennessee-based Alpha Metallurgical Resources reported a $34 million first quarter loss in May, citing “poor market conditions and economic uncertainty caused by shifting tariff and trade policies,” and said it planned to reduce capital expenditures from its previous forecast. Its shares were up almost 7%.
While environmentalists have kept a hawk’s eye on the hefty donations from the oil and gas industry to Trump and other Republicans’ campaign coffers, it appears that the coal industry is the fossil fuel sector getting specific special treatment, despite being far, far smaller. The largest coal companies are worth a few billion dollars; the largest oil and gas companies are worth a few hundred billion.
But coal is very important to a few states — and very important to Donald Trump.
The bituminous coal that has metallurgical properties tends to be mined in Appalachia, with some of the major producers and exporters based in Tennessee and Alabama, or larger companies with mining operations in West Virginia.
One of those, Alliance Resource Partners, shipped almost 6 million tons of coal overseas. Its chief executive, Joseph Craft, andhis wife, Kelly, the former ambassador to the United Nations, are generous Republican donors. Craft was a guest at the White House during the signing ceremony for the coal executive orders.
Representatives of Warrior, Alpha Metallurgical, and Alliance Resources did not respond to a requests for comment.
While coal companies and their employees tend to be loyal Republican donors, the relative small size of the industry puts its financial clout well south of the oil and gas industry, where a single donor like Continental Resources’s Harold Hamm can give over $4 million and the sector as a whole can donate $75 million. This suggests that Trump and the Senate’s attachment to coal has more to do with coal’s specific regional clout, or even the aesthetics of coal mining and burning compared to solar panels and wind turbines.
After all, anyone can donate money, but in Trump’s Washington, only one resource can be beautiful and clean.
Two former Department of Energy staffers argue from experience that severe foreign entity restrictions aren’t the way to reshore America’s clean energy supply chain.
The latest version of Congress’s “One Big, Beautiful Bill” claims to be tough on China. Instead, it penalizes American energy developers and hands China the keys to dominate 21st century energy supply chains and energy-intensive industries like AI.
Republicans are on the verge of enacting a convoluted maze of “foreign entity” restrictions and penalties on U.S. manufacturers and energy companies in the name of excising China from U.S. energy supply chains. We share this goal to end U.S. reliance on Chinese minerals and manufacturing. While at the U.S. Department of Energy and the White House, we worked on numerous efforts to combat China’s grip on energy supply chains. That included developing tough, nuanced and, importantly, workable rules to restrict tax credit eligibility for electric vehicles made using materials from China or Chinese entities — rules that quickly began to shift supply chains away from China and toward the U.S. and our allies.
That experience tells us that the rules in the Republican bill will have the opposite effect. In reality, they will make it much more difficult for U.S. companies to move supply chains away from Chinese control. The GOP’s proposed restrictions require every developer of a critical minerals project, advanced manufacturing facility, or clean energy power plant to sift through their supply chains and contracts for any relationship with a Chinese (or Russian, Iranian, or North Korean) entity. Using a Chinese technology license, or too many subcomponents, or materials produced in China — even if there are few or no alternatives — would be enough to render a company ineligible for the very incentives they need to finance and build new U.S. energy production or manufacturing facilities.
This would put companies in the position of having to prove the absence of Chinese entanglements (and guarantee that there will be none in the future) to qualify for tax credits, an all but impossible task, particularly given the untested set of new rules. Huge portions of the supply chain have flowed through China for decades, including 65% of global lithium processing and 97% of solar wafer manufacturing. American companies are already working to distance themselves from Chinese expertise and components, but the complex, commingled nature of global supply chains and corporate business structures make it infeasible to flip the switch overnight.
On top of that, the latest version of the bill would impose a brand new tax on any new solar and wind projects that have too much foreign entity “assistance,” while providing the Treasury Secretary carte blanche for determining what that might be. The result: An impossible bind, whereby the very sectors that need the most support to disentangle from China are now the ones most penalized by the new Republican “foreign entity” restrictions.
The fact is that China is ahead, not behind, in many energy sectors, and America desperately needs help playing catch-up. Ford’s CEO has called Chinese battery and electric vehicle technologies “an existential threat” to U.S. automaking. In energy supply chains for nuclear, solar, batteries, and critical minerals, China is not merely producing cheap knockoffs of American inventions, it is churning outcutting-edge battery chemistries, advancedmanufacturing processes, and high-speedcharging systems, all at lower cost. And at least until the Inflation Reduction Act enacted incentives for U.S. manufacturing and deployment, the gap between the U.S. and China waswidening.
These untested foreign entity rules will widen that gap once more. Since the start of the year, developers have abandoned more than $14 billion in domestic clean energy deployment and manufacturing projects, citing the uncertain tariff and tax policy environment, and that was before the new tax on solar and wind. New analysis from Energy Innovation finds that the latest version of the bill would reduce U.S. generation capacity by 300 gigawatts over the next decade — multiple times what we will need to power new data centers for artificial intelligence. Stopping clean energy projects in their tracks is also likely to trigger an energy price shock by constraining the very energy technologies that can be built most quickly. In the end we will cede not only our supply chains to China, but also our competitive edge in the race for AI and manufacturing dominance.
Fortunately, we have all the ingredients in this country already to achieve energy leadership. The U.S. boasts deep capital markets, a highly skilled manufacturing and construction workforce, a strong consumer economy driving demand, and, in spite of recent attacks, the world’s greatest universities and national labs. We simply need policy to provide a workable path for companies to invest with certainty, bring factories back to the United States, hire American workers, and learn to produce these technologies at scale.
With the Inflation Reduction Act’s domestic production incentives and supply chain restrictions, hundreds of companies stepped up over the past few years and made that bet, pouring billions of dollars into American supply chains. Should they be enacted, the reconciliation bill’s foreign entity rules would slam the brakes on all that activity, playing right into China’s hands.
There is a way to apply a set of carefully crafted restrictions to wean us off Chinese supply chains, but we cannot afford to saddle American energy with new taxes and red tape. If we scatter rakes across the floor for companies to step on, they will just throw up their hands and send their investments overseas, leaving us more reliant on China than before.
