Donald Trump’s administration is to reconsider the official finding that greenhouse gases are harmful to public health, a move that threatens to rip apart the foundation of the US’s climate laws, amid a stunning barrage of actions to weaken or repeal a host of pollution limits upon power plants, cars and waterways.
Trump’s Environmental Protection Agency (EPA) issued an extraordinary cavalcade of pollution rule rollbacks on Wednesday, led by the announcement it would potentially scrap a landmark 2009 finding by the US government that planet-heating gases, such carbon dioxide, pose a threat to human health.
The so-called endangerment finding, which followed a supreme court ruling that the EPA could regulate greenhouse gases, provides the underpinning for all rules aimed at cutting the pollution that scientists have unequivocally found is worsening the climate crisis.
Despite the enormous and growing body of evidence of devastation caused by rising emissions, including trillions of dollars in economic costs, Trump has called the climate crisis a “hoax” and dismissed those concerned by its worsening impacts as “climate lunatics”.
Lee Zeldin, the EPA administrator, said the agency would reconsider the endangerment finding due to concerns that it had spawned “an agenda that throttles our industries, our mobility, and our consumer choice while benefiting adversaries overseas”.
Zeldin wrote that Wednesday was the “most consequential day of deregulation in American history” and that “we are driving a dagger through the heart of climate-change religion and ushering in America’s Golden Age”.
Zeldin boasted about the changes and said his agency’s mission is to “lower the cost of buying a car, heating a home and running a business”.
Environmentalists reacted with horror to the announcement and vowed to defend the overwhelming findings of science and the US’s ability to address the climate crisis through the courts, which regularly struck down Trump’s rollbacks in his first term. “The Trump administration’s ignorance is trumped only by its malice toward the planet,” said Jason Rylander, legal director at the Center for Biological Diversity’s Climate Law Institute.
“Come hell or high water, raging fires and deadly heatwaves, Trump and his cronies are bent on putting polluter profits ahead of people’s lives. This move won’t stand up in court. We’re going to fight it every step of the way.”
In all, the EPA issued 31 announcements within just a few hours that take aim at almost every major environmental rule designed to protect Americans’ clean air and water, as well as a livable climate.
The barrage included a move to overturn a Biden-era plan to slash pollution spewing from coal-fired power plants, which itself was a reduced version of an Obama administration initiative that was struck down by the supreme court.
The EPA will also revisit pollution standards for cars and trucks, which Zeldin said had imposed a “crushing regulatory regime” upon auto companies that are now shifting towards electric vehicles, consider weakening rules limiting sooty air pollution that’s linked to an array of health problems, potentially axe requirements that power plants not befoul waterways or dump their toxic waste and will consider further narrowing how it implements the Clean Water Act in general.
The stunning broadside of actions against pollution rules could, if upheld by the courts, reshape Americans’ environment in ways not seen since major legislation was passed in the 1970s to end an era of smoggy skies and burning rivers that became the norm following American industrialization.
Pollutants from power plants, highways and industry cause a range of heart, lung and other health problems, with greenhouse gases among this pollution driving up the global temperature and fueling catastrophic heatwaves, floods, storms and other impacts.
“Zeldin’s EPA is dragging America back to the days before the Clean Air Act, when people were dying from pollution,” said Dominique Browning, director of the Moms Clean Air Force. “This is unacceptable. And shameful. We will oppose with all our hearts to protect our children from this cruel, monstrous action.”
The EPA’s moves come shortly after its decision to shutter all its offices that deal with addressing the disproportionate burden of pollution faced by poor people and minorities in the US, amid a mass firing of agency staff. Zeldin has also instructed that $20bn in grants to help address the climate crisis be halted, citing potential fraud. Democrats have questioned whether these moves are legal.
Former EPA staff have reacted with shock to the upending of the agency.
“Today marks the most disastrous day in EPA history,” said Gina McCarthy, who was EPA administrator under Obama. “Rolling these rules back is not just a disgrace, it’s a threat to all of us. The agency has fully abdicated its mission to protect Americans’ health and wellbeing.”
The Trump administration has promised additional environmental rollbacks in the coming weeks. The Energy Dominance Council that the president established last month is looking to eliminate a vast array of regulations in an effort to boost the fossil fuel industry, the interior secretary, Doug Burgum, told the oil and gas conference CeraWeek in Houston on Wednesday. “We will come up with the ways that we can cut red tape,” he said. “We can easily get rid of 20-30% of our regulations.”
