"EPA owes it to Americans to put people’s health first—not give hidebound corporations more time to keep using outdated chemicals," said one critic.
In a reversal of his past position and what critics are calling yet another betrayal of his "Make America Healthy Again" campaign pledge, US President Donald Trump announced Thursday that his administration is loosening limits on so-called "super pollutant" hydrofluorocarbons used in air conditioners and refrigerators at the expense of the environment and climate.
Trump and Environmental Protection Agency Administrator Lee Zeldin spun the move as a measure that will "save American families and businesses more than $2.4 billion" by revising "costly overreaching restrictions" imposed during the Biden administration "limiting the type of refrigerants American businesses and families can use."
"Today, the Trump EPA is fulfilling President Trump’s promise to lower costs and is fixing every problem we can under the authority Congress gave us," Zeldin said. "Our actions allow businesses to choose the refrigeration systems that work best for them, saving them billions of dollars. This will be felt directly by American families in lower grocery prices.”
Grocery prices have continued to rise during Trump’s second term, driven by the administration's erratic trade wars and actual war on Iran. Critics of Thursday's move argue that it will do little to reduce consumer costs, while increasing pollution and health risks for American families.
“It’s nice that they are paying attention to affordability, but if they want to make a difference, it’s tariffs and the Iran War," Ryan Young, a senior economist at the Competitive Enterprise Institute, a libertarian think tank, told NOTUS, estimating that the move would save consumers about $2 per year.
Hydrofluorocarbons (HFCs) are called “super pollutants” because they trap far more heat in the atmosphere than carbon dioxide, even though they are emitted in much smaller quantities. They were originally introduced to replace ozone-depleting chemicals like chlorofluorocarbons (CFCs) that ravaged the ozone layer.
However, scientists soon realized that HFCs are extremely powerful greenhouse gases in their own right. As air conditioning use and demand grows worldwide, so has HFC use.
As the EPA's own website acknowledges on its "Operation: Disrupt HFCs" webpage:
HFCs are potent greenhouse gases... with high global warming potential. HFCs are commonly utilized as refrigerants, aerosol propellants, foam blowing agents, solvents, and fire retardants across residential, commercial, and industrial applications. The major source of HFC emissions is their use as refrigerants—for example, in air conditioning systems in both vehicles and buildings. Emissions occur during manufacturing, as well as through leaks, servicing, and disposal of equipment containing HFCs.
Former EPA Assistant Administrator Joseph Goffman said in a statement Thursday that "families are already stretched thin by high grocery bills and everyday expenses, and weakening safeguards on these super-polluting refrigerant chemicals isn’t going to change that."
"Even manufacturers are saying this delay likely won’t lower prices for consumers because supplies of these chemicals are already being phased down in favor of cleaner, innovative replacements," he added.
Stephen Yurek, president and CEO of the Air-Conditioning, Heating, and Refrigeration Institute (AHRI)—an industry lobby—warned that the "reckless" new policy could actually cause refrigerant prices to increase.
“This rule works against basic supply and demand,” Yurek said. “By extending the compliance deadline, the EPA is maintaining and even increasing demand in the market for existing refrigerants while supply continues to fall under the AIM Act."
The American Innovation and Manufacturing (AIM) Act of 2020, bipartisan legislation signed by Trump during his first term, directed the EPA to "phase down the production and consumption of listed HFCs in the United States by 85% by 2036" and "facilitate the transition to next-generation technologies that do not rely on HFCs."
As of this year, more than 170 countries—including the United States—plus the European Union have ratified the Kigali Amendment to the Montreal Protocol, the main global agreement to phase down HFCs.
Yurek explained that "instead of falling, refrigerant prices are likely to rise, resulting in higher service costs, and higher costs for consumers."
Addressing the EPA's reversal on HFCs, Goffman said, "All this action does is slow the shift to cleaner technologies while risking continued releases of climate super pollutants and leaving families to face the much greater costs and health threats of dangerous climate change."
"EPA owes it to Americans to put people’s health first—not give hidebound corporations more time to keep using outdated chemicals," he added. "Americans deserve affordable groceries that don’t come at the expense of the strong safeguards they count on to keep our families safer, not sicker.”
The EPA move comes amid mounting calls by over 160 civil rights, environmental, faith, health, and labor groups to fire Zeldin over his agency's deregulation spree.
“The EPA has one job, to protect the health and welfare of the American people," said one critic. "But, yet again, the Trump EPA is choosing polluters over people.”
The US Environmental Protection Agency on Thursday proposed postponing enforcement of vehicle emissions standards enacted during the Biden administration, a move that critics warned will worsen air pollution, one of the leading risk factors for premature death in the United States and around the world.
EPA Administrator Lee Zeldin proposed delaying Biden-era emission standards for light- and medium-duty vehicles for two years until model year 2029, claiming that implementation of the policy meant to ensure that a majority of new light vehicles sold in 2032 were electric is "unattainable," and that Americans "overwhelmingly rejected" electric vehicles.
“Freedom is the foundation of this nation, and this includes the freedom to choose the car you drive. The American people have been very clear; they do not want EVs forced upon them,” said Zeldin, who took more than $400,000 in Big Oil campaign donations during his tenure in the New York state Legislature and US Congress, and who questions the scientific consensus on climate change.
Zeldin claimed the proposal "is projected to save over $1.7 billion" for US automakers, "providing hundreds of dollars saved per vehicle for American families," and "aims to return EPA regulations to reality, restoring consumer choice, protecting good paying American jobs, and strengthening the nation’s global competitiveness."
It will also kill people. More than 100,000 people die prematurely in the United States each year due to breathing polluted air. According to a 2024 Environmental Protection Network analysis, President Donald Trump’s rollbacks of pollution rules could cause the deaths of nearly 200,000 people in the United States by 2050.
“In its latest unconscionable act, Trump’s EPA looked at a rule intended to protect public health from toxic tailpipe pollutants while saving tens of thousands of lives, and decided it could wait," Public Citizen Climate Program deputy director Deanna Noël said Friday.
"The decision will not just cost lives; it will cost working-class people more money in medical bills, more missed days of work, and more years chained to volatile gas prices," Noël continued.
"Working families are already stretched thin. Everything from groceries to home insurance to gas is getting more expensive, with no end in sight," she added. "Delaying commonsense emissions standards will only make communities sicker and send costs higher. The EPA’s entire reason for existing is to protect public health and the environment. Yet under this administration, it has been weaponized to serve corporate interests over the American public, no matter the cost.”
According to the advocacy group Climate Power, fossil fuel industry interests spent more than $445 million during the 2024 election cycle on campaign donations, lobbying, and other efforts to bolster Trump and other Republican candidates and causes.
Responding to Zeldin's announcement, Natural Resources Defense Council clean vehicles director Kathy Harris said in a statement that “the EPA has one job, to protect the health and welfare of the American people. But, yet again, the Trump EPA is choosing polluters over people."
“Delaying these standards is going to mean more toxic pollutants spewing from tailpipes, and more soot and smog in our cities," she continued. "That means more asthma, more heart attacks, and more lung disease."
“EPA Administrator Lee Zeldin claims to want to provide clean air and clean water, but time after time he is acting to increase pollution," Harris added. "The Trump administration’s war on our health continues unabated.”

Zeldin's proposal is part of a wider Trump administration push to roll back Biden’s efforts to promote electric vehicles, and serves Trump's "drill, baby, drill" energy policy. Last year, Transportation Secretary Sean Duffy ordered the cancellation of Biden-era fuel efficiency and emissions standards for cars and light trucks
During Trump’s second term, the EPA has moved to repeal or replace stronger carbon emission limits on fossil-fueled power plants, revoked California’s ability to enact stricter vehicle emissions rules, and signaled plans to overturn the agency’s finding that greenhouse gases are a public health hazard.
The EPA has also revoked the long-standing “endangerment finding” that allowed it to pass climate regulation, stopped counting the monetary value of reducing pollution, weakened water and wetland protections, rolled back regulations limiting so-called “forever chemicals” in drinking water, dramatically cut or eliminated environmental justice programs, reduced enforcement of environmental violations, dismantled advisory and scientific panels, removed all mentions of human-caused climate change from its website, and more.
Committing $144 million to study microplastics while subsidizing fossil fuels by nearly $31 billion a year is like trying to clean up an oil spill with a spoon while the tanker is still spewing.
At a time when the science is clear, and action is overdue, the Trump administration’s STOMP initiative—aimed at measuring and removing microplastics from the human body—is a convenient distraction that delays real action. We do not need more studies to understand microplastics in our bodies. We need policies that prevent them from getting there in the first place.
For years, scientists have warned that we are breathing, eating, and drinking plastic. Microplastics—which contain more than 4,200 chemicals known to be hazardous to human health—are in our blood, lungs, and unborn babies.
And while there’s something validating about the Trump administration finally acknowledging this problem, putting microplastics on a watch list is not protection. Instead, this declared "war on microplastics" is a gift in disguise to the industries driving the crisis.
“Make America Healthy Again” was a rallying cry: Take on the corporate polluters, clean up our food supply, eliminate toxic chemicals, and hold the chemical industry accountable. The MAHA Report acknowledged that microplastics are found in "the blood and urine of American children and pregnant women,” and promised action from the Department of Health and Human Services (DHHS), the Environmental Protection Agency (EPA), and the National Institutes of Health (NIH).
The problem is that the only real way to fix it is to stop it at the source. That means taking on the fossil fuel industry driving plastic production—an industry to which this administration has shown deep loyalty.
That was the promise. But instead, the Trump administration gave us plastic straws and put single-use plastics back in our National Parks. They slashed the EPA's budget nearly in half—the very agency responsible for the new microplastics plan—and fired more than 1,000 of its scientists. They dismantled the agencies that protect us from chemical disasters and exposure to harmful hazards, like lead. They ramped up glyphosate production and appointed chemical-industry lobbyists to leadership roles within the EPA. They’re also weakening the Toxic Substances Control Act and rolling back protections on PFAS in drinking water.
While EPA Administrator Lee Zeldin claims the administration is holding itself “to the highest standards to protect the health of every American,” it continues to gut science, weaken laws, and hollow out the very institutions responsible for protecting public health—giving polluting industries a free pass to keep producing more.
Even MAHA advocates are beginning to see through the rhetoric. In a recent letter to the EPA, they urged:“The EPA must choose whether it will uphold a chemical status quo or honor the promise to make this country healthy again. The public is watching. Families are organizing. Scientists are sounding the alarm.”
Microplastics don’t just randomly end up in our bodies. They come from a system designed to produce endless plastic at any cost. That system is fueled by oil, gas, and coal. Nearly 99% of plastics are made from fossil fuels. Committing $144 million to study microplastics while subsidizing fossil fuels by nearly $31 billion a year is like trying to clean up an oil spill with a spoon while the tanker is still spewing.
The Trump administration has put a spotlight on a serious health crisis. The problem is that the only real way to fix it is to stop it at the source. That means taking on the fossil fuel industry driving plastic production—an industry to which this administration has shown deep loyalty. As Secretary of the US DHHS, Robert F. Kennedy, Jr., put it on Fox News: “A lesson we were all supposed to learn in kindergarten is that you clean up after yourself. You don't force the public to do it.”
The coming months will show whether this administration is serious about action or simply delivering lip service to a disillusioned MAHA ahead of the midterms. If the administration is really committed to making Americans healthy again, it must act where it matters: Set enforceable limits on microplastics in drinking water, restore strong chemical safety laws, halt new plastic production, rebuild the EPA and Centers for Disease Control and Prevention, and revoke the red-carpet access it has granted industry within regulatory agencies.
Above all, it could truly end the war on microplastics by backing a global plastics treaty that limits production in the first place.
Because you cannot detox a body you are still poisoning.
"Ultimately, if this rule is finalized, human health will suffer, and taxpayers will be left with the cost of cleaning up their rivers and drinking water."
Amid mounting calls for the removal of US Environmental Protection Agency Administrator Lee Zeldin, the EPA chief on Thursday announced proposed changes to coal ash rules, which critics blasted as another gift to polluters at the expense of public health.
Officially called coal combustion residuals (CCR), "coal ash—the toxic byproduct of burning coal—contains hazardous pollutants, including arsenic, boron, cadmium, chromium, lead, radium, and selenium, which are linked to serious health harms such as cancer, heart disease, and brain damage, among other lasting impacts," noted the Natural Resources Defense Council (NRDC).
Specifically, as The Associated Press reported, the EPA "proposed easing standards for monitoring and protecting groundwater near some coal ash sites, rolling back rules forcing the cleanup of entire coal properties instead of just places where ash was dumped. The revisions would also make it easier to reuse coal ash for other purposes."
While Zeldin claimed the "commonsense changes to the CCR regulations reflect EPA's commitment to restoring American energy dominance, strengthening cooperative federalism, and accommodating unique circumstances at certain CCR facilities," Environmental Protection Network's Marc Boom responded that "letting companies avoid cleaning up waste sites that may be leaching toxic metals into groundwater and nearby waterways, while weakening protections and accountability, is not common sense."
"EPA's top priority should be protecting people's health, not sacrificing it for corporate expediency," argued Boom, senior director of public affairs at the group, which is made up of former agency staff. "EPA may call these safeguards 'impractical,' but anyone living downstream of coal ash sites holding thousands of tons of waste knows that requiring cleanup and monitoring is a necessary and basic standard."
NRDC senior attorney Becky Hammer called the pending rollback just "the latest in a long, long, line of Trump administration giveaways to fossil fuels industries," which have also included repealing EPA rules that targeted chemical pollution from coal-fired power plants, declaring a national energy emergency, and scrapping the 2009 "endangerment finding" that underpins all federal climate regulations.
Other advocacy organizations were similarly critical of Thursday's announcement. Daniel Estrin, Waterkeeper Alliance's general counsel and legal director, pointed out that "coal ash is contaminating water at nearly every active and retired coal plant in the US."
"By gutting these safeguards, EPA is abandoning its duty to protect impacted communities by allowing preventable contamination of our rivers, lakes, streams, and groundwater," he said. "The longer the coal industry is allowed to delay closing and cleaning up its toxic waste sites, the more difficult and costly it becomes to fix the damage. By failing to enforce the law, EPA is letting polluters continue harming people and wildlife without accountability."
Like Estrin and Hammer, Earthjustice senior counsel Lisa Evans framed that proposal as "yet another handout to the coal power industry at the expense of our health, water, and wallets," and warned of the dangers of delaying closure and cleanup. She said that "ultimately, if this rule is finalized, human health will suffer, and taxpayers will be left with the cost of cleaning up their rivers and drinking water."
Although "the Trump administration just took a sledgehammer to the health protections in place for toxic coal pollution," Evans added, "Earthjustice has successfully defended these safeguards in court and will do so again."
Nick Torrey, senior attorney at the Southern Environmental Law Center, which has secured commitments to clean up over 270 million tons of coal ash in US communities, similarly said that "doing the bidding of industrial polluters instead of protecting ordinary families and clean water is shameful, but we are ready to keep fighting against coal ash pollution."
"Letting coal-burning utilities set the agenda has been a disaster for communities across the South, resulting in coal ash spills and hundreds of families forced to live on bottled water for years under the threat of coal ash pollution," Torrey highlighted. "The Trump administration and coal ash polluters want to take us back to the bad old days of arsenic, lead, and mercury from coal ash contaminating our water."
In addition to facing a flurry of lawsuits over policies prioritizing the climate-wrecking fossil fuel industry—whose campaign cash helped President Donald Trump return to the White House last year—the administration has recently been hit with demands to remove Zeldin from more than 160 advocacy groups and nearly 300 health experts.
"This EPA's actions to put polluters first, at the expense of our health, are dangerous and will be deadly," states the health experts' open letter, organized and released Thursday by the Climate Action Campaign. "Administrator Zeldin has abandoned his sworn duty and must be held accountable for his agenda."
"We cannot tolerate an EPA administrator who treats our families as expendable."
Hundreds of health experts are demanding the removal of Environmental Protection Agency Administrator Lee Zeldin over his gutting of key regulations that they say will endanger Americans' livelihoods.
A letter released Thursday by Climate Action Campaign outlines Zeldin's threats to public health and explains why he should not be serving as the top US environmental regulator.
"Administrator Zeldin is pursuing a deregulatory agenda that will result in a massive increase in health-damaging air pollution, toxic chemicals, and climate-heating greenhouse gases," says the letter, which is signed by nearly 300 medical experts, including physicians, nurses, and public health researchers.
"And just last month, the administration laid bare its decision to no longer count the economic value of health benefits when setting Clean Air Act rules," the letter adds, "refusing to acknowledge the value of lives saved, hospital visits avoided, and lost work and school days prevented."
The letter also points to the EPA's February decision to revoke the so-called "endangerment finding," which gave the agency authority to regulate greenhouse gases as threats to public health.
Repealing this finding, the letter contends, "will increase the frequency and severity of climate disasters."
According to a Wednesday report from The Associated Press, Zeldin celebrated the EPA's revocation of the finding while delivering a keynote address at the Heartland Institute, a right-wing think tank that has long pushed climate denialism.
"Today is a moment to celebrate," Zeldin said at the event. "It is a day to celebrate vindication."
Margie Alt, director of the Climate Action Campaign, said her group decided to organize the letter among medical experts because "Lee Zeldin is too dangerous to ignore."
"When health experts—the people who see the effects of pollution on their patients every single day—say enough is enough, the rest of us need to pay attention," said Alt. "Zeldin is not just failing Americans. He is actively endangering us. We cannot tolerate an EPA administrator who treats our families as expendable."
This is the second "Game Over Zeldin" letter, following another from over 160 advocacy groups, including Climate Action Campaign and Moms Clean Air Force, last month.
"The wreckage of Lee Zeldin's EPA will be measured in lives lost, jobs destroyed, the costs of illnesses that could have been prevented, and communities devastated."
A month after President Donald Trump and Environmental Protection Agency Administrator Lee Zeldin announced what they celebrated as the "single largest deregulatory action in US history," a coalition of over 160 civil rights, environmental, faith, health, and labor groups came together Tuesday to call for the EPA chief's ouster.
Zeldin was confirmed by Senate Republicans and a trio of Democrats just over a week after Trump returned to power in January 2025. The "Game Over Zeldin" coalition, led by the Climate Action Campaign (CAC) and Moms Clean Air Force, argued in an open letter that no other EPA administrator "in history—Democratic or Republican—has so brazenly betrayed the agency's core mission" to "protect human health and the environment."
"Zeldin has dismantled protections that keep our kids, families, and climate safe, and our air and water clean," the letter notes. "He slashed vital funding, gutted agency staff, and has rigged the system to put corporate polluters first, at the expense of our health. Zeldin's EPA has rejected science and health data—and is refusing to count the value of human lives and health—in order to erode commonsense public health safeguards. He has decimated environmental justice programs and hard-fought progress—entirely eliminating the Office of Environmental Justice and External Civil Rights."
Dominique Browning, director and co-founder of Moms Clean Air Force, pointed out in a Tuesday statement that "in just the past few months, he has supported the Trump administration in using taxpayer money to prop up the coal industry; he has made it easier for polluters to spew mercury—a potent neurotoxin that damages the developing brains of babies—into our air and waterways; and he has rolled back the endangerment finding in an attempt to sabotage EPA's ability to cut climate pollution."
The 2009 endangerment finding underpins all federal climate policy. David Arkush of the watchdog Public Citizen—which is also part of the diverse coalition behind the new letter—warned at the time that if allowed to stand, the repeal "will hamstring the government's ability to combat the most terrible environmental threat in human history, harming Americans and the world for decades to come."
Young Americans and a coalition of environmental and public health organizations swiftly filed a pair of lawsuits over the rollback. Another group of 24 states, joined by various US cities and counties, sued last week. The most recent filing is expected to be consolidated with the first coalition's case, according to The New York Times, "making for one of the largest legal challenges to date against the Trump administration's unraveling of federal climate policy."
The new letter stresses the consequences of that unraveling, stating that "because of Zeldin's directives, we will suffer more health-damaging air pollution and be exposed to more toxic chemicals in our homes, in our food, in our products, and in our water. Zeldin's rollbacks will lead to more carbon dioxide and methane pollution that will contribute to worsening climate disasters."
"Families across the country, whether rural or urban, are already struggling with the consequences of Zeldin's actions," the letter adds. "The damage he is doing will span generations. Zeldin is deepening environmental injustices and will leave a terrible legacy for our children and grandchildren."

CAC director Margie Alt declared Tuesday that "the wreckage of Lee Zeldin's EPA will be measured in lives lost, jobs destroyed, the costs of illnesses that could have been prevented, and communities devastated. We will be paying the price for decades to come."
"Zeldin ignored science as well as the legal and moral precedent," she said. "Instead, he looked at the numbers and made a choice: He decided that corporate bottom lines matter more than our lives. He decided you and your family are expendable. After a year on the job, it is clear that Zeldin is either unable or unwilling to uphold his oath of office or the EPA's fundamental mission. So let us be clear: Our lives are not expendable. Our health is not expendable. Our climate is not expendable. Lee Zeldin must go."
Other organizations that signed on to the letter include Beyond Plastics, Cherokee Concerned Citizens, Clean Air Council, Clean Water Action, Climate Hawks Vote, Earthjustice, Environmental Working Group, Environmental Protection Network, GreenLatinos, Indivisible Action Coalition, Physicians for Social Responsibility, Service Employees International Union, Sierra Club, Union of Concerned Scientists (UCS), and more.
"Administrator Zeldin's established pattern of placing polluter profits above the health and safety of people across the country cannot stand," said UCS president and CEO Gretchen Goldman. "The science establishing harm to human health and the environment from global warming emissions is undeniable. The unprecedented, climate-fueled heatwave a large swath of the United States has been experiencing is only the latest example."
"The public deserves an EPA administrator who will face the challenge of the climate crisis and fossil fuel and toxics pollution head on with proven policy solutions," she argued, "not actively serve as an agent of destruction beholden to the whims of oil, gas, and chemical industry executives and an authoritarian, anti-science US president."
Who's responsible for rolling back the endangerment finding? We believe it is time to name names so future generations—and future climate justice tribunals—will know who is responsible for incinerating our futures.
The February rollback of the "endangerment finding"—which provides the legal basis for regulating climate change—was many years in the works. It's the ultimate payback for a politically engaged fossil fuel industry and the climate criminals who use their wealth, power, and position to block efforts to help us transition to a post-oil, gas, and coal era.
Who's responsible for rolling back the endangerment finding? We believe it is time to name names so future generations—and future climate justice tribunals—will know who is responsible for incinerating our futures. Researchers at the Climate Accountability Research Project have tracked several of the key individuals working to undermine climate protection for the last two years
On February 12, 2026, Lee Zeldin, the head of the Environmental Protection Agency (EPA), announced the rescission of the 2009 Greenhouse Gas Endangerment Finding, repealing regulations for GHG emissions of motor vehicles. According to The New York Times, a small group of fossil fuel-funded right-wing operatives have pushed to roll back government regulation of greenhouse gases for the past 16 years and have finally succeeded. Myron Ebell, a leading climate denier and fellow at the libertarian think tank Competitive Enterprise Institute, stated that “no amount of public support would have done anything if there hadn’t been those four people: Russ and Jeff and John and Mandy.”
So who the heck are “Russ and Jeff, and John and Mandy?” Russell Vought, Jeffrey Clark, Mandy Gunasekara, and Jonathan Brightbill are well-known operatives within right-wing circles. For example, Russell Vought, President Donald Trump’s director of the US Office of Management and Budget, and Jeffrey B. Clark, former acting administrator of the Office of Information and Regulatory Affairs, are veterans from the first Trump administration.
Rolling back the endangerment finding will have devastating and irreversible consequences to the planet.
Clark has been fighting the government’s ability to regulate greenhouse gases since 2005. In 2022, Vought was vice president of the Heritage Foundation and managed Project 2025, the blueprint for many Trump initiatives. Vought hired Clark to draft executive orders for a future Republican president to easily reverse President Joe Biden’s climate initiatives. In 2023, Clark described climate change regulation as part of a plot to “‘meta control’ Americans.” Following the 2024 election, Vought and Clark were both asked to serve in Trump’s second administration where they were able to push for the repeal of the endangerment finding.
The “Mandy and Jonathan” are lesser known right-wing operatives. Mandy Gunasekara is an environmental attorney, former chief of staff for the EPA during the first Trump administration, and author of the Project 2025 report chapter on reforming the EPA. Gunasekara fought against policies from the Biden administration regarding emission reduction and self-identified as the “chief architect” behind Trump’s withdrawal from the Paris Agreement. The Climate Accountability Research Project identified Gunasekara as a Climate Criminal in 2024 because of her historical role in rolling back greenhouse gas regulations.
In 2015, Gunasekara infamously handed the late Sen. James Inhofe (R-Okla.) a snowball to use as a prop on the Senate floor as “proof” that climate change wasn’t a real threat. Gunasekara was serving as an aide to Sen. Inhofe, who was considered to be one of Congress’ most outspoken climate skeptics at the time. Gunasekara was also a former visiting fellow with the Heritage Foundation’s Center for Energy, Climate, and Environment, where she helped draft a policy agenda that “unleashes American energy production, and reduces barriers to economic freedom.”
Following Gunasekara’s resignation from the EPA in 2019, she founded the Energy45 Fund, a 501(c)(4) nonprofit organization “to promote the Trump energy agenda” and inform the public on the "environmental and economic gains made under the Trump administration.” The sources of funding for this organization have remained anonymous, and the organization has even been dubbed as a “dark money group” by Open Secrets.
In 2023, the Heritage Foundation published Project 2025, which featured Gunasekara’s 32-page chapter “Mandate for Leadership,” outlining a conservative agenda to move the EPA away from its focus on climate change. Key policy proposals outlined in her chapter include resetting scientific advisory boards, scaling back greenhouse gas regulation programs, and updating the 2009 endangerment finding. Gunasekara’s chapter also included the “Day One Executive Order,” which included a list of immediate actions to be taken on the first day of President Trump’s second term, with orders like “stop all grants to advocacy groups and review which potential federal investments will lead to tangible environmental improvements” and “revise guidance documents that control regulations such as the social cost of carbon.”
Jonathan Brightbill is currently the general counsel of the US Department of Energy. Brightbill argued against Obama-era climate policies while serving in the Justice Department in the first Trump administration.
In 2022, Gunasekara and Brightbill began their secret campaign to end the endangerment finding, in which they secured $2 million in funding from right-wing groups like the Heritage Foundation. The funding allowed Gunasekara and Brightbill to draft regulatory documents that would simplify the abandonment of the endangerment finding. Over the years, the two collected an “arsenal of information” to dispute the scientific evidence of climate change. The evidence collected along with their detailed plans of attack helped the Trump administration end the endangerment finding.
Rolling back the endangerment finding will have devastating and irreversible consequences to the planet. There will come a day, maybe sooner than we think, when climate criminals like “Russ and Jeff and John and Mandy” will be held to account.
Sierra Club said the rollback "puts the public at greater risk of heart and lung disease, cancer, and even premature death, as well as causing severe neurological damage to fetuses and children.”
The Trump administration on Friday finalized its rollback of clean air regulations limiting mercury and other toxic pollutants from power plants, sparking condemnation from public health and environmental advocates who warned that the move will increase the risk of death or serious illness for millions of people in the United States.
The US Environmental Protection Agency (EPA) said it is repealing the Mercury and Air Toxics Standards (MATS), which were implemented during the Biden administration in order to protect people from mercury and other toxic air pollutants—including arsenic, lead, and chromium—from fossil fuel power plants.
The Trump administration contends that rescinding MATS will lower financial costs for utilities running older coal-fired plants during a period of rapidly rising demand from consumer and data centers powering artificial intelligence systems.
“The Biden-Harris administration’s anti-coal regulations sought to regulate out of existence this vital sector of our energy economy," EPA Administrator Lee Zeldin said Friday at the Mills Creek Power Plant, a coal-fired facility in Louisville, Kentucky. "The Trump EPA knows that we can grow the economy, enhance baseload power, and protect human health and the environment all at the same time."
However, the Sierra Club said Friday that "rolling back the new and more protective [MATS] will allow coal- and oil-fired power plants to emit more damaging pollution that puts the public at greater risk of heart and lung disease, cancer, and even premature death, as well as causing severe neurological damage to fetuses and children."
"According to the Sierra Club’s Trump Coal Pollution Dashboard, reversing the 2024 improvements and reverting to the 2012 standards will allow the dirtiest coal-fired power plants to emit 50% more mercury pollution," the group added. "In May 2025, the Trump administration exempted 68 power plants—including some of the biggest polluters in the nation—from MATS after soliciting exemption requests from big polluters over email."
Sierra Club Beyond Coal campaign director Laurie Williams called the MATS rollback "a direct attack on the health of Americans."
Last June, Sierra Club was a key part of a coalition of environmental and community groups that sued the Trump administration over the exemptions.
“These protections from mercury and other toxic pollution existed to protect communities from reckless polluters," Sierra Club campaign organizing strategist Bonnie Swinford said Friday. "By repealing these protections, the Trump administration is giving handouts to the coal industry elites—and waging war on the public’s ability to hold polluters accountable."
The Environmental Protect Network also decried the MATS repeal, saying it "will allow hundreds of facilities across 45 states to avoid meeting critical safety standards—jeopardizing public health, degrading ecosystems, and disproportionately harming children, pregnant people, and communities already overburdened by pollution."
"This is no way to make America healthy again."
Moms Clean Air Force co-founder and director Dominique Browning focused on the harms to children the rollback will inflict.
"The science is clear, and profoundly alarming. No amount of mercury is safe for babies’ developing brains," she said. "Mercury is a dangerous neurotoxin that damages the architecture of babies’ and children’s developing brains."
“The mercury rules were working," Browning argued. "Toxic emissions from US coal plants were dropping, and water bodies were getting cleaner. But now EPA Administrator Zeldin’s rollback... will allow coal plants to emit more toxic heavy metals like mercury, chromium, and lead—pollutants that contaminate our air, fall into our lakes and waterways, and poison our food supply."
"This is no way to make America healthy again," she added, referring to one of President Donald Trump's campaign slogans.
Julie McNamara, associate policy director at the Union of Concerned Scientists' Climate and Energy Program, said in a statement Friday: “Once again, the Trump administration is abandoning science and abandoning statute to give polluters a free pass. And once again, the Trump administration is doing so at the expense of people’s health."
National Resources Defense Council senior attorney John Walke asserted that "the coal industry is in decline, and dismantling clean air protections won’t bring it back."
“It will only lead to more asthma attacks, more heart problems, and more premature deaths, especially in communities living in the shadow of coal plants," Walke added. "We have a right to breathe clean air, and we will fight for that right even if Trump’s EPA refuses to.”
The EPA’s newest decision will allow power plants to emit more brain-damaging mercury and dangerous soot pollution, putting frontline communities at especially greater risk of heart and lung disease, cancer, and premature death.

Friday's EPA announcement followed the agency's repeal earlier this month of the endangerment finding, the Obama-era rule empowering climate regulation over the past 15 years that treated six greenhouse gases caused by burning fossil fuels as a single air pollutant for regulatory purposes.
Speaking at a Friday press conference in Washington, DC organized by Moms Clean Air Force, Talia, a local fourth grade student, said that “climate disasters are becoming more common, and they’re hurting our planet, our health, and the future of kids like me."
“Adults in the government are supposed to protect kids from climate change and not ignore it," she said, adding in a message to Trump officials that "we are taught to listen to scientists and doctors and moms—why don’t you listen to them?”
"This shameful and dangerous action," said one expert, "is rooted in falsehoods, not facts, and is at complete odds with the public interest and the best available science."
Over a dozen young Americans as well as a coalition of environmental and public health groups on Wednesday filed a pair of legal challenges against President Donald Trump's administration for repealing the "endangerment finding" that enabled federal policies aimed at combating the fossil fuel-driven climate emergency.
Environmental Protection Agency Administrator Lee Zeldin announced the long-anticipated move last week. The coalition of groups responded with a petition at the US Court of Appeals for the District of Columbia Circuit that names him and the EPA.
"The endangerment finding has been the backbone of climate policy for 17 years, protecting us from air pollution that endangers public health and welfare—including greenhouse gases that are driving climate change," explained Lawrence Hafetz, legal director at Clean Air Council, one of the groups behind the case, in a statement.
"By repealing the finding, we are sweeping the single deadliest type of pollution, climate pollution, under the rug," Hafetz continued. "Deadly floods, droughts, wildfires, and hurricanes are harming our health, our communities, and our economy. This climate chaos plan is decimating the EPA's ability to act when we need protections more than ever."
Gretchen Goldman, president and CEO at the Union of Concerned Scientists, another plaintiff, argued that "EPA's repeal of the endangerment finding and safeguards to limit vehicle emissions marks a complete dereliction of the agency's mission to protect people’s health and its legal obligation under the Clean Air Act."
"This shameful and dangerous action by the Trump administration and EPA Administrator Zeldin is rooted in falsehoods, not facts, and is at complete odds with the public interest and the best available science," she noted. "Heat-trapping emissions and global average temperatures are rising—primarily due to the burning of fossil fuels—contributing to a mounting human and economic toll across the nation."
In the lead-up to the repeal, institutions worldwide concluded that 2025 was among the hottest years on record, a group of global experts declared that "current economic models systematically underestimate climate damage," and another international team of scientists warned in a review of climate tipping points that Earth is at risk of a hothouse trajectory.
Despite such findings, Trump has waged a sweeping war on the climate since he returned to office last year, thanks in part to campaign cash from the fossil fuel industry. In addition to repealing the 2009 endangerment finding—which the administration celebrated as the "single largest deregulatory action in US history"—he has declared a "national energy emergency" and ditched a long list of organizations and treaties, including the Paris Agreement.
Friends of the Earth legal director Hallie Templeton said Wednesday that "today's lawsuit makes clear that we will not idly stand by while EPA blatantly refutes its core mission to protect the environment and public health from dangerous pollution."
Templeton and David Pettit, an attorney at the Center for Biological Diversity’s Climate Law Institute, stressed that with the repeal, the Trump administration is unlawfully choosing big polluters at the expense of the public and the planet."
"We're suing to stop Trump from torching our kids' future in favor of a monster handout to oil companies," said Pettit. "Nobody but Big Oil profits from Trump trashing climate science and making cars and trucks guzzle and pollute more. Consumers will pay more to fill up, and our skies and oceans will fill up with more pollution. The EPA's rollbacks are based on political poppycock, not science or law, and the courts should see it that way."
Other organizations involved in the case include the American Public Health Association, American Lung Association, Center for Community Action and Environmental Justice, Environmental Defense Fund, Natural Resources Defense Council, Physicians for Social Responsibility, Public Citizen, Sierra Club, and more.
Also on Wednesday, 18 children and young adults from across the United States filed a separate petition at the same court challenging the EPA repeal. They are represented by Our Children's Trust and Public Justice, which have worked on various youth climate cases.
"My Catholic faith teaches me to care for all life and protect the most vulnerable, and it teaches that children are a gift," said lead petitioner Elena Venner. "I now struggle to imagine bringing a child into a world where the air is unsafe and the climate is increasingly unstable. The EPA's repeal of the endangerment finding violates my First Amendment right to practice my faith and my Fifth Amendment rights to life and liberty."
"I have asthma, and worsening pollution harms my health and makes it harder for me to breathe and live fully outdoors," Venner explained. "When the air is thick with the pollution of fossil fuel-burning cars and trucks and ever-increasing wildfire smoke, I feel it in my chest, and I am reminded that something as basic as breathing is no longer guaranteed. That is not the life today or the future my generation deserves."
"The only beneficiaries will be polluting industries, many of which are among President Trump’s largest donors,” the lawmakers wrote.
A group of 31 Democratic senators has launched an investigation into a new Trump administration policy that they say allows the Environmental Protection Agency to "disregard" the health impacts of air pollution when passing regulations.
Plans for the policy were first reported on last month by the New York Times, which revealed that the EPA was planning to stop tallying the financial value of health benefits caused by limiting fine particulate matter (PM2.5) and ozone when regulating polluting industries and instead focus exclusively on the costs these regulations pose to industry.
On December 11, the Times reported that the policy change was being justified based on the claim that the exact benefits of curbing these emissions were “uncertain."
"Historically, the EPA’s analytical practices often provided the public with false precision and confidence regarding the monetized impacts of fine particulate matter (PM2.5) and ozone," said an email written by an EPA supervisor to his employees on December 11. “To rectify this error, the EPA is no longer monetizing benefits from PM2.5 and ozone.”
The group of senators, led by Sen. Sheldon Whitehouse (D-RI), rebuked this idea in a letter sent Thursday to EPA Administrator Lee Zeldin.
"EPA’s new policy is irrational. Even where health benefits are 'uncertain,' what is certain is that they are not zero," they said. "It will lead to perverse outcomes in which EPA will reject actions that would impose relatively minor costs on polluting industries while resulting in massive benefits to public health—including in saved lives."
"It is contrary to Congress’s intent and directive as spelled out in the Clean Air Act. It is legally flawed," they continued. "The only beneficiaries will be polluting industries, many of which are among President [Donald] Trump’s largest donors."
Research published in 2023 in the journal Science found that between 1999 and 2020, PM2.5 pollution from coal-fired power plants killed roughly 460,000 people in the United States, making it more than twice as deadly as other kinds of fine particulate emissions.
While this is a staggering loss of life, the senators pointed out that the EPA has also been able to put a dollar value on the loss by noting quantifiable results of increased illness and death—heightened healthcare costs, missed school days, and lost labor productivity, among others.
Pointing to EPA estimates from 2024, they said that by disregarding human health effects, the agency risks costing Americans “between $22 and $46 billion in avoided morbidities and premature deaths in the year 2032."
Comparatively, they said, “the total compliance cost to industry, meanwhile, [would] be $590 million—between one and two one-hundredths of the estimated health benefit value."
They said the plan ran counter to the Clean Air Act's directive to “protect and enhance the quality of the Nation’s air resources so as to promote the public health and welfare,” and to statements made by Zeldin during his confirmation hearing, where he said "the end state of all the conversations that we might have, any regulations that might get passed, any laws that might get passed by Congress” is to “have the cleanest, healthiest air, [and] drinking water.”
The senators requested all documents related to the decision, including any information about cost-benefit modeling and communications with industry representatives.
"That EPA may no longer monetize health benefits when setting new clean air standards does not mean that those health benefits don’t exist," the senators said. "It just means that [EPA] will ignore them and reject safer standards, in favor of protecting corporate interests."
