Administrator Lee Zeldin announced the cancellations weeks ago, but the agency has refused to provide details.

New documents obtained by Senate Democrats on the Environmental and Public Works Committee this week shed more light on the inner workings of EPA Administrator Lee Zeldin’s attempt to shut down hundreds of climate- and environmental justice-related grants.
Senators Sheldon Whitehouse of Rhode Island and Lisa Blunt Rochester of Delaware secured a list of 477 grants the EPA has “targeted for termination,” along with damning internal emails from the agency that showed its management knew that many of its terminations to date violated contracts with grantees.
Democrats on the committee sent a letter to Zeldin on Tuesday alleging that EPA was breaking the law and demanding that it rescind any grant termination notices it has sent out.
The list of grants appears to align with a press release the EPA published on March 10 stating that Zeldin had canceled more than 400 grants worth more than $1.7 billion in his fourth round of spending cuts. This was in addition to the $20 billion “green bank” program Zeldin has been attempting to cut. EPA did not say which grants it was canceling or why in any of these rounds of cuts, but last week, the Sierra Club obtained a partial list of what appeared to be the first three rounds through a Freedom of Information Act request.
While nearly half of the grants on the Sierra Club’s list were for research into low-carbon construction materials like steel and cement, all of the funds on the new list were awarded to nonprofits, Tribes, cities, states, and universities for projects in disadvantaged communities.
Many of the grants are from three Inflation Reduction Act programs: the Collaborative Problem-Solving Cooperative Agreement Program, which funds nonprofit efforts to create new partnerships with companies, local governments, or medical service providers to address environmental or public health issues; the Community Change Grant Program, which supports activities that reduce pollution and increase climate resilience; and the Government-to-Government Program, which subsidizes state and local government pilot projects and other activities that improve the environment and public health.
They include awards of between $20,000 and $20 million for community gardens, solar projects, air quality monitoring, energy efficiency upgrades, wildfire preparedness, clean water initiatives, protection during heatwaves, rural economic development, and job training, among many others.
Just over 130 of the grants are reported as being “financially closed,” or having a $0.00 remaining balance, meaning the EPA’s claim that it canceled more than 400 grants may have been inflated.
There is also overlap with the list the EPA provided to the Sierra Club. Heatmap identified 18 grants that appear on both. For these 18 grants, the Sierra Club list shows that they were canceled on the 21st or 22nd of February. The list obtained by the senators shows that they were “awarded” on those dates, but labels them “financially closed” or having a $0.00 remaining balance.
In their letter to Zeldin, Senate Democrats asserted Congress’ power over the federal purse, noting that the law specifically “directed the EPA to distribute $3 billion to improve environmental protection in communities facing economic hardship.” An internal email from the EPA’s general counsel notes that some of the grants were terminated on the basis that they funded DEI or environmental justice initiatives that “conflict with the Agency’s policy of prioritizing merit, fairness, and excellence in performing our statutory functions.” The senators’ letter argues quite the opposite — that these grants were meant to ensure a healthy environment for all Americans.
Secondly, they write that “any attempt to withhold these funds violates the Impoundment Control Act.” That’s a reference to a 1974 law that prohibits the executive branch from holding back congressionally appropriated funds without permission from Congress. The letter also admonishes Zeldin for violating federal court injunctions on President Trump’s funding freeze.
Lastly, the senators accuse the agency of knowingly violating the terms of its own contracts, citing an internal email from EPA’s Office of General Counsel which admits as much. The email acknowledges that many of the cancellation letters sent to grantees cited grounds for termination that were not valid under the grant contracts. At this, the Office of General Counsel essentially shrugs, noting that “no decision to retract the terminations is forthcoming,” and that grantees can dispute the decision or sue the agency if they want to.
The letter includes a series of 12 questions for the EPA, including requests for every termination letter sent to grantees and an explanation of what the agency plans to do with “the alleged $2 billion in federal funds ‘saved’ by EPA and DOGE grant terminations.”
In a statement to the Associated Press, the EPA confirmed that it received the letter, but that it has no plans to stop canceling grants. “As the Trump administration reins in wasteful spending of taxpayer dollars, EPA will continue terminating assistance agreements in line with terms and conditions,” the statement said.
Here is the full list of canceled grants released by the senators, published for the first time in a searchable, sortable format:

The opinion covered a host of actions the administration has taken to slow or halt renewables development.
A federal court seems to have struck down a swath of Trump administration moves to paralyze solar and wind permits.
U.S. District Judge Denise Casper on Tuesday enjoined a raft of actions by the Trump administration that delayed federal renewable energy permits, granting a request submitted by regional trade groups. The plaintiffs argued that tactics employed by various executive branch agencies to stall permits violated the Administrative Procedures Act. Casper — an Obama appointee — agreed in a 73-page opinion, asserting that the APA challenge was likely to succeed on the merits.
The ruling is a potentially fatal blow to five key methods the Trump administration has used to stymie federal renewable energy permitting. It appears to strike down the Interior Department memo requiring sign-off from Interior Secretary Doug Burgum on all major approvals, as well as instructions that the Interior and the Army Corps of Engineers prioritize “energy dense” projects in ways likely to benefit fossil fuels. Also struck down: a ban on access to a Fish and Wildlife Service species database and an Interior legal opinion targeting offshore wind leases.
Casper found a litany of reasons the five actions may have violated the Administrative Procedures Act. For example, the memo mandating political reviews was “a significant departure from [Interior] precedent,” and therefore “required a ‘more detailed justification’ than that needed for merely implementing a new policy.” The “energy density” permitting rubric, meanwhile, “conflicts” with federal laws governing federal energy leases so it likely violated the APA, the judge wrote.
What’s next is anyone’s guess. Some cynical readers may wonder whether the Supreme Court will just lift the preliminary injunction at the administration’s request. It’s worth noting Casper had the High Court’s penchant for neutralizing preliminary injunctions in mind, writing in her opinion, “The Court concludes that the scope of this requested injunctive relief is appropriate and consistent with the Supreme Court’s limitations on nationwide injunctions.”
On China’s H2 breakthrough, vehicle-to-grid charging, and USA Rare Earth goes to Brazil
Current conditions: In the Atlantic, Tropical Storm Fernand is heading northward toward Bermuda • In the Pacific, Tropic Storm Juliette is active about 520 miles southwest of Baja California, with winds of up to 65 miles per hour • Temperatures are surging past 100 degrees Fahrenheit in South Korea.
Nearly two weeks ago, Vineyard Wind sued one of its suppliers, GE Vernova, to keep the industrial giant from exiting the offshore wind project off the coast of Nantucket in Massachusetts. Now a U.S. court has ordered GE Vernova to finish the job, saying it would be “fanciful” to imagine a new contractor could complete the installation. GE Vernova had argued that Vineyard Wind — a 50/50 joint venture between the European power giant Avangrid and Copenhagen Infrastructure Partners — owed it $300 million for work already performed. But Vineyard Wind countered that the manufacturer remains on the hook for about $545 million to make up for a catastrophic turbine blade collapse in 2024, according to WBUR. “The project is at a critical phase and the loss of [Vineyard Wind]’s principal contractor would set the project back immeasurably,” the Suffolk County Superior Court Judge Peter Krupp wrote in his decision, repeatedly using the name of GE Vernova’s renewables subsidiary. “To pretend that [Vineyard Wind] could go out and hire one or more contractors to finish the installation and troubleshoot and modify [GE Renewables’] proprietary design without [GE Renewables’] specialized knowledge is fanciful.”
Charlotte DeWald fears the world is sleepwalking into tipping points beyond which the Earth’s natural carbon cycles will render climate change uncontrollable. By the time we realize what it means for global weather and agricultural systems that there’s no sea ice in the Arctic sometime in the 2030s, for example, it may be too late to try anything drastic to buy us more time. Much of the discourse around what to do concerns a specific kind of geoengineering called stratospheric aerosol injections, essentially spraying reflective particles into the sky to block the sun’s heat from permeating the increasingly thick layer of greenhouse gases that prevent that energy from naturally radiating back into space. That’s something DeWald, a former Pacific Northwest National Laboratory researcher and climate scientist by training who specialized in modeling aerosol-cloud interactions, knows all about. But her approach is different, using a technology known as mixed-phase cloud thinning, a process similar to cloud seeding. “The idea is that you could dissipate clouds over the Arctic to release heat from the surface to, for example, increase sea ice extent or thickness or integrity,” she told me. “There’s some early modeling that suggests that it could yield significant cooling over the Arctic Ocean.”
With all that context, you can now appreciate the exclusive bit of news I have for you this morning: DeWald is launching a new nonprofit called the Arctic Stabilization Initiative to “evaluate whether targeted interventions can slow dangerous” warming near the Earth’s northern pole. So far, ASI has raised $6.5 million in philanthropic funding toward a five-year budget goal of $55 million to study whether MCT, as mixed-phase cloud thinning is known, could help save the Arctic. The nonprofit has an advisory board stacked with veteran Arctic scientists and put together a “stage-gated” research plan with offramps in case early modeling suggests MCT won’t work or could cause undue environmental damage. The project also has an eye toward engaging with Indigenous peoples and “will ground all future work in respect for Indigenous sovereignty, before any field-based research activity is pursued.” The statement harkens to Harvard University’s SCoPEx trial, a would-be outdoor experiment in spraying reflective aerosols into the atmosphere over Sweden that ran aground after researchers initially failed to consult local stakeholders and a body representing the Indigenous Saami people in the northern reaches of Nordic nations came out against the testing. (By repeatedly invoking ASI’s nonprofit status, DeWald also seemed to draw a contrast with for-profit stratospheric aerosol injection startup Stardust Solutions, which last year Heatmap’s Robinson Meyer reported had raised $60 million.) “We are continuing to move toward critical planetary thresholds without a bible plan for things like tipping points,” DeWald said. “That was the inflection point for me.”

China just took yet another step closer to energy independence, despite its relatively tiny domestic reserves of oil and gas, kicking off the world’s largest project to blend hydrogen into the natural gas system. As part of the experiment, roughly 100,000 households in the center of the Weifang, a prefecture-level city in eastern Shandong province between Beijing and Shanghai, will receive a blend of up to 10% hydrogen through existing gas pipes. The pilot’s size alone “smashes” the world record, according to Hydrogen Insight. Whether that’s meaningful from a climate perspective depends on how you look at things. A fraction of 1% of China’s hydrogen fuel comes from electrolyzer plants powered by clean renewables or nuclear electricity. But the People’s Republic still produces more green hydrogen than any other nation. Last year, the central government made cleaning up heavy industry with green hydrogen a higher priority — a goal that’s been supercharged by the war in Iran. Therein lies the real biggest motivator now. While China relies on imports for natural gas, swapping out more of that fuel for domestically generated hydrogen allows Beijing to claim the moral high ground on emissions and air pollution — all while becoming more energy independent.
Meanwhile, China’s container ships are the latest sector to experiment with going electric and forgoing the need for costly, dirty bunker fuel. A 10,000-ton fully electric cargo vessel capable of carrying 742 shipping containers just started up operations in China this week, according to a video posted on X by China’s Xinhua News service.

The ability of electric vehicles to serve as distributed energy resources, charging in times of low demand and discharging back onto the grid when demand peaks, has long been a dream of EV enthusiasts and DER advocates alike. California’s PG&E utility launched a small bi-directional charging program in 2023, allowing owners of Ford F-150 Lightnings to use their trucks as home backup power, and eventually feed energy back onto the grid. The utility added a host of General Motors EVs to the program back in 2025. On Monday, it announced its latest vehicle participant: Tesla’s Cybertruck. The Tesla vehicle will be the first in the program to run on alternating current, which simplifies the equipment necessary and lowers costs for consumers, according to PG&E’s announcement.
In January, I told you about the then-latest company to benefit from President Donald Trump’s dabbling in what you might call state capitalism with American characteristics: USA Rare Earth. The vertically integrated company, which aims to mine rare earths in Texas, took big leaps forward in the past year toward building factories to turn those metals into the magnets needed for modern technologies. For now, however, the company needs ore. On Monday, USA Rare Earth announced plans to buy Brazilian rare earth miner Serra Verde in a deal valued at $2.8 billion in cash and shares. The transaction is expected to be complete by the end of the third quarter of this year. The company pitched the move as a direct challenge to China, which dominates both the processing of rare earths mined at home and abroad. “The world has become too dependent on a single source and it’s high time to break that dependency,” USA Rare Earth CEO Barbara Humpton told CNBC’s “Squawk Box” on Monday.
As if we needed more evidence that the data center backlash is “swallowing American politics,” here’s Heatmap’s Jael Holzman with yet another data point: According to tracking from the Heatmap Pro database, fights against data centers now outnumber fights against wind farms in the U.S. That includes both onshore and offshore wind developments. “Taken together,” Jael wrote, “these numbers describe the tremendous power involved in the data center wars.”
Fights over AI-related developments outnumber those over wind farms in the Heatmap Pro database.
Local data center conflicts in the U.S. now outnumber clashes over wind farms.
More than 270 data centers have faced opposition across the country compared to 258 onshore and offshore wind projects, according to a review of data collected by Heatmap Pro. Data center battles only recently overtook wind turbines, driven by the sudden spike in backlash to data center development over the past year. It’s indicative of how the intensity of the angst over big tech infrastructure is surging past current and historic malaise against wind.
Battles over solar projects have still occurred far more often than fights over data centers — nearly twice as many times, per the data. But in terms of megawatts, the sheer amount of data center demand that has been opposed nearly equals that of solar: more than 51 gigawatts.
Taken together, these numbers describe the tremendous power involved in the data center wars, which is now comparable to the entire national fight over renewable energy. One side of the brawl is demand, the other supply. If this trend continues at this pace, it’s possible the scale of tension over data centers could one day usurp what we’ve been tracking for both solar and wind combined.
