Donald Trump’s Backdoor Gasoline Tax

Overturning the basis for America’s tailpipe emissions rules could actually raise prices at the pump — according to the Trump administration itself.

It hasn’t attracted much attention, but a document filed by the Trump administration last week admits to something important: The Trump administration believes that it is going to make gasoline more expensive for Americans.

That disclosure came in a technical analysis filed by the Environmental Protection Agency to support its attempt to repeal all carbon dioxide rules under the Clean Air Act. The document is meant to bolster the EPA’s case that carbon dioxide is not a dangerous air pollutant, and that the agency should therefore withdraw all tailpipe pollution limits for cars and trucks.

The document also shows that President Trump will struggle to meet his own campaign promises around energy. When he ran for president last year, Trump promised to cut energy and electricity prices by “at least half” within 12 months of taking office.

Now, the president’s policies are — by his own administration’s admission — likely to cause energy prices to rise. At least compared to the world where those policies never went into effect.

The admission comes on page 10 of the filing in a chart and associated discussion. It’s a confusing image at first glance, so take a look at it, then I’ll walk through it.

The rollback would affect light-duty, medium-duty, and heavy-duty vehicles — that is, everything from a small Toyota Corolla sedan to a Freightliner Cascadia semi. Because of that, the chart shows both gasoline prices (in red) and diesel prices (in black).

The solid black and red lines are what the government projected would happen to gasoline and diesel prices two years ago based on then-current policy. (They’re labeled AEO 2023 Reference because they came from the Energy Information Administration’s 2023 Annual Energy Outlook, the big yearly compendium of long-term market trends.)

The dashed black and red lines are what the government projected would happen to gasoline and diesel prices in its most recent 2025 Annual Energy Outlook. As you can see, in that report, federal analysts considerably downgraded their forecast for future gasoline and diesel prices — projecting gas prices, in particular, as much as 75 cents cheaper than in 2023. (These lines are labeled AEO 2025 Reference.)

The dotted red and black lines are what the government now thinks will happen when it rolls back the EPA’s tailpipe pollution rules. (These lines are labeled 2025 Alt Transportation, which is the name of the deregulatory scenario in the annual energy report.) As you can see, these — the Trump rollback scenario — come in far above the current 2025 forecast, particularly for gasoline. In other words, the Trump administration believes that rolling back the EPA tailpipe standards will raise gasoline prices.

The document itself acknowledges this: “For the AEO 2025 Alternative Transportation case, the difference compared to AEO 2023 is smaller, yet still lower than the prices in the AEO 2023, and the difference remains relatively stable over time.”

In other words, the document concedes that gas prices under Trump’s rollback will be more expensive — that is, much closer to the 2023 projections — than they were projected to be with the Biden-era regulations in place. The Trump document argues that’s okay: As long as gas prices are cheaper now than they were projected to be in 2023, Americans will have less to save by driving more fuel-efficient cars, so the EPA can roll back its pollution rules without worrying about the resulting increase in gas prices.

It’s an odd argument, one that relies heavily on the global decline in gasoline price forecasts from 2023 to 2025, which has little to nothing at all to do with Trump’s policymaking. As the filing says elsewhere, global gasoline markets can go up and down for many reasons, including “(1) changes in U.S. policies; (2) international incidents (e.g., wars); (3) changes in policies by international organizations (e.g., OPEC); and (4) changes in supply and demand of gasoline and diesel.” If gasoline prices go up significantly in the future, it could throw one argument for Trump’s rollback into question.

The problem for the EPA — and for the president — is that removing gas mileage rules means that American consumers will, as a whole, consume more gasoline. That might be good for the oil and gas industry, and it might slightly reduce the costs of a new car or appliance. But it will drive up energy costs as well — especially for Americans who already own a car or who are not in the market for a new appliance.

This analysis also makes Trump’s rollback oddly captive to the vagaries of Chinese policy. One reason that global gasoline price forecasts have stalled since 2023 is because Chinese gas demand has plateaued due to the explosive growth of that country’s EV industry. The Trump EPA is saying, in essence: Because China has switched en masse to EVs, it’s cheaper for Americans to keep driving gasoline cars. The follow-on innovation effects of this — the fact that American carmakers will fall behind — are not considered in the sample.

But the concession points to a deeper problem for Trump. The president campaigned on a promise to cut energy costs for Americans upon taking office. But over the past seven months, his administration has aggressively rolled back energy efficiency and fuel economy rules. It has imposed tariffs on some energy imports and moved to crack down on some zero-carbon forms of electricity production. At the same time, Trump has personally demanded that OPEC increase drilling to lower gasoline prices.

This Trump rollback — and the resulting rise in projected gasoline demand — comes as the overall energy cost environment has grown more inflationary. As I’ve previously written, electricity prices show every sign of rising in the coming years because of natural gas supply constraints, the Trump administration’s renewables policy, and equipment shortages. The president only has five months left — and a year at most — to cut energy prices in half, as he once promised during the campaign. He better get cracking.

Welcome to Climate 101

Your guide to the key technologies of the energy transition.

Welcome to Climate 101

Here at Heatmap, we write a lot about decarbonization — that is, the process of transitioning the global economy away from fossil fuels and toward long-term sustainable technologies for generating energy. What we don’t usually write about is what those technologies actually do. Sure, solar panels convert energy from the sun into electricity — but how, exactly? Why do wind turbines have to be that tall? What’s the difference between carbon capture, carbon offsets, and carbon removal, and why does it matter?

So today, we’re bringing you Climate 101, a primer on some of the key technologies of the energy transition. In this series, we’ll cover everything from what makes silicon a perfect material for solar panels (and computer chips), to what’s going on inside a lithium-ion battery, to the difference between advanced and enhanced geothermal.

There’s something here for everyone, whether you’re already an industry expert or merely climate curious. For instance, did you know that contemporary 17th century readers might have understood Don Quixote’s famous “tilting at windmills” to be an expression of NIMYBism? I sure didn’t! But I do now that I’ve read Jeva Lange’s 101 guide to wind energy.

That said, I’d like to extend an especial welcome to those who’ve come here feeling lost in the climate conversation and looking for a way to make sense of it. All of us at Heatmap have been there at some point or another, and we know how confusing — even scary — it can be. The constant drumbeat of news about heatwaves and floods and net-zero this and parts per million that is a lot to take in. We hope this information will help you start to see the bigger picture — because the sooner you do, the sooner you can join the transition, yourself.

What Goes on Inside a Solar Panel?

The basics on the world’s fastest-growing source of renewable energy.

What Goes on Inside a Solar Panel?

Solar power is already the backbone of the energy transition. But while the basic technology has been around for decades, in more recent years, installations have proceeded at a record pace. In the United States, solar capacity has grown at an average annual rate of 28% over the past decade. Over a longer timeline, the growth is even more extraordinary — from an stalled capacity base of under 1 gigawatt with virtually no utility-scale solar in 2010, to over 60 gigawatts of utility-scale solar in 2020, and almost 175 gigawatts today. Solar is the fastest-growing source of renewable energy in both the U.S. and the world.
