Trump’s Move to Kill the Clean Air Act’s Climate Authority Forever

Rob and Jesse talk through the proposed overturning of the EPA’s “endangerment finding” on greenhouse gases with Harvard Law School’s Jody Freeman.

The Trump administration has formally declared that carbon dioxide and other greenhouse gases are not dangerous pollutants. If the president gets his way, then the Environmental Protection Agency may soon surrender any ability to regulate heat-trapping pollution from cars and trucks, power plants, and factories — in ways that a future Democratic president potentially could not reverse.

On this week’s episode of Shift Key, we discuss whether Trump’s EPA gambit will work, the arguments that the administration is using, and what it could mean for the future of U.S. climate and energy policy. We’re joined by Jody Freeman, the Archibald Cox Professor of Law at Harvard and the director of Harvard’s environmental and energy law program. She was an architect of the Obama administration’s landmark deal with automakers to accept carbon dioxide regulations.

Shift Key is hosted by Jesse Jenkins, a professor of energy systems engineering at Princeton University, and Robinson Meyer, Heatmap’s executive editor.

Here is an excerpt from our conversation:

Robinson Meyer: I just want to make a related question, which is, you can actually say some of the sentences in the DOE report — you can believe tornadoes don’t show any influence from climate change and still believe heatwaves do, and still believe extreme rainfall events do. In fact, you could believe the cost of heat waves getting worse could justify the entire regulatory edifice.

Jody Freeman: What I love about you, Rob, right now, is you’re kind of incensed about little points that might individually sort of be right, maybe each one separately, but none of it adds up to even a chink in the armor. Right? And what’ll have to happen is the scientific community writ large, en masse, is going to have to come back and say, even if one or two or three of these sentences could possibly, plausibly be actually accurate, it does nothing to change the overwhelming —

Jesse Jenkins: It doesn’t matter.

Freeman: Right. What I think is happening is we’re all getting poked and distracted and tweaked into outrage over science, when in fact, the first argument they’re making is the one where they could actually attract some judges and justices to say, Oh wait, maybe you have a little more discretion here to set a threshold level. You know, Maybe it matters that you’re saying nothing we do here in the U.S. will make a difference in the end to global warming, and maybe that is a reason you don’t want to regulate. Hmm, maybe we’ll accept that reason. And that’s what we need, I think, to be more concerned about.

Jenkins: You’re saying, don’t get distracted by the fight over the climate science. That fight is very clear. It’s this legal argument that this isn’t an air pollutant because it’s not a local air pollutant, it mixes globally with all the other CO2, and we can’t, you know, each class of cars is a tiny contributor to that, and so we shouldn’t worry about it —

Freeman: And much of this is a replay, or a rehash of arguments that the George W. Bush administration lost in Massachusetts vs. EPA. So a lot of this is like, let’s take another run at the Supreme Court.

Why Biden’s Climate Law Is Stickier Than It Seems

Any version of the future — even one under Trump — includes bits of the Inflation Reduction Act.

We passed a major milestone over the weekend: the one-year anniversary of President Trump’s One Big Beautiful Bill Act. That piece of legislation — which curtailed the wind and solar tax credits, ended incentives for electric vehicle buyers, and terminated a lot of green industrial policy — was signed into law on July 4, 2025. It also formally ended the era of decarbonization and climate policy experimentation that began when the United States passed the Inflation Reduction Act roughly three years earlier.

Now we’re far enough out to begin assessing the Trump law’s impact. And a fascinating new report, published today by the MIT Center for Energy and Environmental Policy Research, argues that the damage … is not as bad as one might fear — at least in the electricity sector.

‘A Watershed Moment’

On energy inefficiency, global green H2, and New Hampshire’s guerrilla solar

Current conditions: Super Typhoon Bavi is slamming into Guam and the Northern Mariana Islands as the equivalent of a Category 5 hurricane, with sustained wind speeds topping 178 miles per hour • The record-shattering heat dome over the central and eastern United States is easing and shifting westward until mid July • In Europe, however, the heat is continuing, with temperatures hitting 108 degrees Fahrenheit in southern Spain over the weekend.

THE TOP FIVE

1. America’s historic first restart of a nuclear reactor hits a ‘watershed moment’

America’s next nuclear reactor is coming to life via resurrection. For the past two years, Holtec International has been working to bring the single reactor at the decommissioned Palisades nuclear plant in western Michigan back into service. It would be the first time in U.S. history that a permanently shuttered nuclear plant came back online. If successful, a growing list of projects are lining up to follow in Palisades’ footsteps. On Friday, Holtec announced that the Palisades crew had completed “the last of the major projects,” marking a “watershed moment” in the restoration effort. “We’re now focused on safely executing the remaining testing, verification, and operational readiness activities required before startup,” Michael Schultheis, Holtec’s vice president of the plant, said in a statement. “The plant is coming back together, and the professionalism and dedication demonstrated by our workforce continue to move the project forward.”

The New Paper Arguing Biden’s Power Sector Emissions Cuts Are Largely Intact — Even Under Trump

Rob talks with Columbia’s Lily Bermel about where climate policy should go next.

Wait, is the climate policy landscape … in better shape than it looks?

Just over a year ago, President Trump passed the One Big Beautiful Bill Act. It repealed many of the Biden administration’s most aggressive climate policies, including tax credits for solar and wind energy.
