“This Is All a Scam, a Giant Scam”, The Endangerment Finding Controversy Explained

---

“This is all a scam, a giant scam.”

That sentence, delivered from the Roosevelt Room on February 12, 2026, didn’t come from a late-night infomercial or a crypto whistleblower’s final video. It came from the sitting president of the United States, and it was about something most Americans had never heard of: the EPA’s endangerment finding. If you are wondering what that finding is, why someone would call it a scam, and whether the label holds up, you are in exactly the right place.

The Quote That Made Headlines, Context and Origin

On that February Thursday, President Trump signed the repeal of a 2009 scientific determination that declared six greenhouse gases a threat to public health and welfare. Standing alongside EPA Administrator Lee Zeldin, Trump called the original ruling “a disastrous Obama-era policy that severely damaged the American auto industry” and declared it had become the legal foundation for the “Green New Scam”, a phrase he first coined at a New Hampshire rally in December 2023.

He went further: “This determination has no basis in fact... I tell them, don’t worry about it, because it has nothing to do with public health. This was all a scam, a giant scam. This was a rip-off of the country by Obama and Biden.” And with that, the single largest deregulatory action in American history was framed not as a policy disagreement but as the unmasking of a fraud.

Which raises a pretty obvious question.

What the Endangerment Finding Actually Says (And Why It Exists)

Before we can ask whether something is a scam, we have to know what it is. So let’s walk through it.

The endangerment finding is, at its core, a scientific answer to a legal question. In 2007, the Supreme Court ruled in Massachusetts v. EPA that greenhouse gases qualify as “air pollutants” under the Clean Air Act, and it ordered the EPA to determine whether those gases endanger public health and welfare. Two years later, after an exhaustive review of peer-reviewed climate science, the EPA issued its answer: yes, carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride “threaten the public health and welfare of current and future generations.”

From that finding flowed regulations on vehicle tailpipes, power-plant smokestacks, and industrial emissions. It became the legal backbone of federal climate policy for 17 years.

Think of it like this: the finding wasn’t a policy prescription; it was the diagnosis. You cannot fix a problem you refuse to name.

“A Giant Scam” v. 17 Years of Scientific Evidence

Here is where we have to do the uncomfortable work of setting rhetoric next to research.

Independent assessments from the IPCC, the U.S. National Climate Assessments, and the Lancet Countdown on Health and Climate Change have reinforced—not weakened—the original 2009 determination. The 2025 Lancet Countdown report found that 12 of 20 key health indicators tied to climate change had reached record levels. That is not an opinion poll; it is a measurement.

The health harms are well established:

• Extreme heat is now one of the deadliest weather-related phenomena in the United States, with hospital admissions spiking during heatwaves.
• Wildfire smoke, laden with fine particulate matter (PM2.5), triggers asthma attacks, heart attacks, and strokes, sometimes hundreds of miles from the flames.
• Children who live near highways—in other words, kids breathing traffic pollution daily—show up to three times the odds of developing asthma.
• Rising temperatures are expanding the range of infectious diseases like dengue and malaria into regions that were previously unaffected.

Katharine Hayhoe, Chief Scientist at The Nature Conservancy, put it bluntly: “Since the United States Environmental Protection Agency issued its Endangerment Finding in 2009, the scientific evidence connecting greenhouse gas emissions to health impacts from climate change has only grown stronger.” If the finding was a scam in 2009, it has become an astonishingly durable one.

The Legal Sleight-of-Hand, Why Science Wasn’t Even the Fight

Here is the twist that most coverage missed. The EPA’s initial proposal in August 2025 tried to attack the science head-on, relying on a report from the Department of Energy prepared by five scientists with fringe views. But a federal court determined the administration had violated federal law in forming that group, and scientific bodies including the National Academy of Sciences rejected the report’s conclusions.

So when the final rule came out in February 2026, the science was barely mentioned. Instead, the EPA argued something different: that the Clean Air Act was never meant to cover greenhouse gases because their effects are global rather than local. The agency claimed that regulating U.S. vehicle emissions “cannot meaningfully address a worldwide problem.”

There is a big problem with that argument: the Supreme Court explicitly rejected similar reasoning in 2007. The Clean Air Act text does not contain the words “local only.” Harvard Law experts called the final rule “largely unwanted by industry and contradicted by science and law.”

This wasn’t a battle of science versus science. It was a legal rewiring that sidestepped the science entirely.

So, Is It Actually a Scam?, A Straight Answer

Let’s use a metaphor.

Imagine your house has a smoke detector. It goes off whenever there is smoke, which is annoying. A friend visits, points at the detector, and says, “That thing is a scam. It’s just there to control you. Rip it out.” You rip it out. The smoke detector stops beeping. But the smoke is still there—only now you cannot see it until the fire is at the door.

The endangerment finding was the smoke detector. Calling it a scam made for a great soundbite, but it did not change what was burning.

Here is a fact worth sitting with: the repeal’s own final text, buried in the Federal Register, did not claim that greenhouse gases are harmless. It simply asserted the EPA no longer has the authority to act on them. The science is not disputed; it was set aside.

What Happens Next (And Why It Matters to You)

Litigation is already underway. On February 18, 2026, seventeen environmental and public-health organizations filed a petition for review in the D.C. Circuit Court of Appeals. Most legal observers expect the fight to reach the Supreme Court. If the repeal is upheld, the immediate consequences include:

• Elimination of all federal greenhouse gas standards for vehicles.
• A pathway to dismantle emission limits on power plants and factories.
• States left to fill the regulatory vacuum on their own—creating a patchwork where your air quality increasingly depends on your ZIP code.

For drivers, the administration claims vehicle prices will drop. But major automakers have already invested billions in efficiency and electrification, and they may not reverse course simply because federal rules disappear. As for health costs, the EPA’s own cost-benefit analysis showed that in four out of eight scenarios, the economic harms of the repeal outweighed the savings.
