In 2009, Barack Obama’s EPA made a finding. Just a finding — a bureaucratic determination that greenhouse gases “endanger public health and welfare.”
It didn’t sound like much at the time. No new law. No congressional vote. Just some scientists and bureaucrats deciding that carbon dioxide — the gas you exhale with every breath — was a danger that required government intervention.
That single finding has cost Americans over $1 trillion.
It became the legal foundation for every climate regulation that followed. Electric vehicle mandates. Fuel economy standards. Emissions requirements. The entire regulatory apparatus that has made cars more expensive, limited consumer choice, and pushed Americans toward vehicles they don’t want to buy.
This week, Donald Trump is tearing it up.
The Largest Deregulation in American History
EPA Administrator Lee Zeldin posted on X: “This week, we make history. Getting ready to join President Trump to announce the single largest act of deregulation in the history of the USA.”
That’s not hyperbole. The Endangerment Finding is the keystone of federal climate policy. Remove it, and the entire regulatory structure built on top of it becomes legally vulnerable.
White House Press Secretary Karoline Leavitt confirmed the scope: “On Thursday, President Trump will be joined by Administrator Lee Zeldin to formalize the rescission of the 2009 Obama-era Endangerment Finding. This will be the largest deregulatory action in American history, and it will save the American people $1.3 trillion in crushing regulation.”
One point three trillion dollars. That’s not savings for corporations. That’s savings for American families — in lower car prices, lower energy costs, and freedom to buy vehicles that actually meet their needs instead of what Washington dictates.
What the Endangerment Finding Did
To understand why this matters, you have to understand how the regulatory state works.
Congress never passed a law saying the EPA should regulate carbon dioxide. Congress never voted on electric vehicle mandates. Congress never decided that Americans should be forced into smaller, more expensive cars to fight climate change.
The EPA did all of that unilaterally — using the Endangerment Finding as its legal justification.
Here’s how it worked: The Clean Air Act gives EPA authority to regulate “air pollutants” that endanger public health. By declaring that greenhouse gases endangered public health, the EPA gave itself the power to regulate literally everything that produces carbon dioxide.
Cars? Regulated. Power plants? Regulated. Factories? Regulated. Anything that burns fossil fuels? Fair game.
One administrative finding. Trillions of dollars in regulatory burden. Zero congressional votes.
That’s not how democracy is supposed to work. But it’s how the regulatory state has operated for decades.
The Biden EV Mandate
The most obvious example of the Endangerment Finding’s impact is the Biden administration’s effective electric vehicle mandate.
Under rules justified by the Finding, automakers were required to meet increasingly strict emissions standards that were essentially impossible to achieve with gasoline-powered vehicles. The only way to comply was to sell more EVs — whether consumers wanted them or not.
The result? Higher car prices across the board. Automakers passing compliance costs to consumers. Dealers sitting on lots full of electric vehicles that buyers didn’t want. And American families priced out of the new car market entirely.
All because of a 2009 finding that nobody voted for.
Consumer Choice Returns
The final rule rescinding the Endangerment Finding will, according to administration officials, “remove the regulatory requirements to measure, report, certify and comply with federal greenhouse-gas emission standards for motor vehicles.”
Translation: automakers will be able to build cars Americans actually want to buy.
If consumers want electric vehicles, they can buy them. If they want trucks, they can buy trucks. If they want gasoline-powered sedans, those will be available. The government will no longer be in the business of forcing manufacturers to produce vehicles that sit unsold on lots.
This is what a free market looks like. Producers make what consumers want. Prices reflect actual supply and demand, not regulatory compliance costs. And the government stays out of decisions that should be between buyers and sellers.
The Environmental Left Meltdown
The environmental lobby is going to lose their minds over this. Expect apocalyptic rhetoric about “climate catastrophe” and “destroying the planet.”
But here’s what they won’t mention: the Endangerment Finding didn’t save the planet. It just made life more expensive for American families.
Global carbon emissions continued to rise. China and India expanded their use of coal and oil. The developing world industrialized without regard for American regulatory standards.
The only thing the Endangerment Finding accomplished was handicapping American industry while our competitors surged ahead. We made ourselves poorer and less competitive, and the climate didn’t notice.
Trump’s approach is different: make America energy dominant. Produce oil, gas, and coal domestically. Let American innovation develop cleaner technologies naturally, through market incentives rather than government mandates. And stop pretending that regulations that hurt American families are somehow saving the planet.
The Legal Battle Ahead
Environmental groups will sue immediately. That’s guaranteed. They’ll argue the EPA can’t simply reverse a previous administration’s scientific finding. They’ll claim the Clean Air Act requires the regulations to remain in place. They’ll try to get a friendly judge to issue an injunction.
But the Trump administration appears to have prepared for this fight. The rulemaking process has been followed. The legal justifications are documented. And the fundamental argument is strong: the Endangerment Finding was always an overreach of executive authority that Congress never authorized.
The Supreme Court has already signaled skepticism toward regulatory agencies claiming broad powers based on ambiguous statutory language. The “major questions doctrine” — which holds that agencies can’t make decisions of vast economic significance without clear congressional authorization — directly challenges the legitimacy of climate regulations built on the Endangerment Finding.
This fight may ultimately end up at SCOTUS. And given the current Court’s composition, the administration has reason to be confident.
Energy Prices Coming Down
The immediate impact will be felt in energy prices.
The Endangerment Finding justified regulations not just on vehicles but on power plants and industrial facilities. While the initial rule focuses on motor vehicles, Zeldin has signaled that broader rollbacks are coming.
Lower regulatory burden means lower compliance costs. Lower compliance costs mean lower prices for consumers. It’s not complicated — it’s basic economics that the regulatory state has been distorting for decades.
Trump has consistently argued that expanded fossil fuel production will lower energy prices. Repealing the regulatory framework that has constrained that production is the essential first step.
What This Means for You
If you’re in the market for a new car, this means more choices and lower prices.
If you’re paying an electricity bill, this means relief from the regulatory costs that have been driving rates higher.
If you’re filling up at the gas station, this means domestic production can expand without bureaucratic obstacles.
And if you’re a working American who has watched the cost of living climb while politicians lecture you about “saving the planet,” this means someone in Washington finally put your interests ahead of climate ideology.
The Bottom Line
In 2009, Obama’s EPA made a finding that gave the government control over every aspect of American energy production. That finding justified over $1 trillion in regulations that raised prices, limited choices, and burdened families already struggling to make ends meet.
In 2026, Trump is rescinding it.
“The single largest act of deregulation in the history of the USA,” Lee Zeldin called it. And he’s right.
For sixteen years, the Endangerment Finding has been the foundation of climate regulation in America. This week, that foundation crumbles.
Cars will get cheaper. Energy will get cheaper. And Americans will finally be free to make their own choices without Washington bureaucrats deciding what they’re allowed to drive.
That’s not just deregulation. That’s freedom.
