Obama's EPA spent sixteen years telling Americans what kind of cars they could buy, how much they'd cost, and whether their engine could stay running at a red light.
Trump and EPA Administrator Lee Zeldin just ended that entire scheme with a single stroke.
Yesterday in the Roosevelt Room, they eliminated the 2009 Endangerment Finding – the legal foundation Obama used to justify regulations that drove up car prices, forced manufacturers to build vehicles nobody wanted, and made that universally despised start-stop feature standard equipment in two-thirds of new cars.
EPA Endangerment Finding Repeal: Lee Zeldin Delivers Largest Deregulation in U.S. History
Zeldin called it what it was – the "Holy Grail of the climate change religion."
For sixteen years, this one Obama-era decision gave bureaucrats the power to regulate carbon dioxide as a pollutant endangering public health.
Never mind that humans exhale CO2 with every breath and plants need it to survive.
Obama's EPA declared six greenhouse gases – including ones that vehicles don't even emit – somehow combined to create an "unknown amount" of atmospheric warming that "may" endanger health through "varied causal chains."
That tortured logic became the excuse for everything from vehicle emission standards to power plant regulations to forcing automakers to install features like start-stop systems that kill your battery without any real environmental benefit.
The Supreme Court's recent decisions in West Virginia v. EPA and Loper Bright made clear that agencies can't bury their heads in the sand about massive regulatory costs – and that major policy decisions belong to Congress, not bureaucrats making creative interpretations of forty-year-old laws.
Trump's EPA Uses Climate Models To Prove Zero Impact From U.S. Vehicle Emissions
Here's the kicker that'll make climate activists' heads explode.
Zeldin's team ran the same computer models the Obama and Biden administrations used to justify their regulations.
The result?
Even if the United States eliminated every single greenhouse gas emission from every single vehicle on American roads, there would be no material impact on global climate indicators through 2100.
Zero.
The entire regulatory cascade – trillions in costs, decades of restricted consumer choice, government-mandated vehicle features – accomplished nothing for the climate while hammering American families with hidden taxes every time they bought a car.
How The EPA Deregulation Saves $2,400 On Every New Car Purchase
The average new car costs nearly $50,000 now – up 43% over the past decade.
Obama and Biden's emission standards played a starring role in that price explosion.
Trump's deregulation saves Americans over $1.3 trillion by eliminating the requirements to measure, report, certify, and comply with federal greenhouse gas standards for motor vehicles.
That translates to an average savings of $2,400 per vehicle for American families.
Not theoretical savings decades from now – actual money you won't have to hand over to a car dealer to pay for regulations that accomplished nothing except making bureaucrats feel important.
Automakers can now build vehicles people actually want to buy instead of gaming federal credit systems to meet arbitrary emission targets that had zero real-world impact.
EPA Eliminates Start-Stop Feature Mandate That Two-Thirds of Drivers Hated
Obama's EPA created something called "off-cycle credits" in 2012 – a regulatory loophole that let automakers claim greenhouse gas reductions on paper by installing features like automatic engine start-stop.
You know the one – where your engine dies at every red light, drains your battery, and gives you that lovely feeling of your car stalling in traffic.
About 60% of new cars came standard with this "green technology" that delivered questionable emission reductions while annoying everyone who drove them.
Zeldin heard about it from countless Americans in all fifty states – people who didn't just dislike start-stop, they passionately advocated for killing it.
Now it's dead.
Manufacturers can still install it if they want, but they won't get federal credits for forcing it on customers who never asked for it.
Consumer choice just made a comeback.
Obama and Democrats Attack Trump's $1.3 Trillion Vehicle Emissions Rollback
Obama issued a statement claiming Americans will now be "less safe, less healthy and less able to fight climate change" – as if the country survived just fine before his administration invented the authority to regulate plant food as a pollutant.
The Sierra Club called it "climate denialism as official government policy" and warned about litigation floods.
Democrat governors in California and Wisconsin claimed the repeal "ignores basic science and denies reality."
Here's the reality they're denying – their regulations cost trillions, accomplished nothing for global temperatures, and made vehicles unaffordable for working families trying to get to their jobs.
Trump's EPA followed the law as written, not as climate activists wished it to be.
Congress never authorized the EPA to reshape America's entire energy economy through administrative fiat based on speculative computer models about temperatures in 2100.
The Supreme Court made that crystal clear.
Greenhouse Gas Regulations For Power Plants and Auto Industry Face Legal Challenges
This isn't just about cars.
The Endangerment Finding served as the legal prerequisite for regulations targeting power plants, oil and gas operations, and federal lands – regulations that reshaped America's energy economy without congressional authorization.
All of that now lacks legal foundation.
Zeldin's EPA is expected to follow up by reconsidering the mandatory Greenhouse Gas Reporting Program, Clean Power Plan 2.0, coal plant wastewater regulations, and the "Social Cost of Carbon" metric that Obama invented to justify crushing regulations.
Environmental groups are already promising years of litigation.
Good luck with that strategy after Loper Bright eliminated judicial deference to agency interpretations and after the Supreme Court's major questions doctrine requires clear congressional authorization for regulations with massive economic consequences.
Trump's team did something Obama's EPA refused to do – they actually read the Clean Air Act and discovered it was designed to address local and regional air pollution that directly harms health, not speculative global warming theories requiring "varied causal chains" to maybe cause harm decades from now.
That's not creative lawyering.
That's following the law.
