Hi, I'm Robinson Meyer, the founding Executive editor of Heat Map News. It is Friday, February 20th. This morning the Supreme Court threw out President Trump's most aggressive tariffs ruling that the International Emergency Economic Powers act of 1977, usually called IPA, does not allow the President to impose broad indiscriminate tariffs on other countries. Had Congress intended to convey the distinct and extraordinary power to impose tariffs, it would have done so expressly, chief Justice John Roberts wrote.
A
It was a bit of a stitched together decision.
B
Clarence Thomas, Samuel Alito and Brett Kavanaugh dissented, while Neil Coruset, Jamie Coney Barrett and the Chief justice ruled with the liberals, although the liberals only concurred with some of the decision.
A
But it takes away a major tool
B
of economic and diplomatic policy making for President Trump. There were really two sets of tariffs affected by this decision.
A
One was a set of so called
B
reciprocal tariffs imposed on most countries in the world and set between 10 and 50%. And the second were what Trump called the fentanyl tariffs on China, Mexico and Canada. Now, the President basically immediately followed up this ruling by saying he would impose a 10% universal tariff on all countries. We're still trying to understand how exactly he would do that and what it would mean and we'll talk about it on the show, but we wanted to have a conversation on an emergency basis here on an emergency Shift Key episode about what this means for clean energy and what this could also mean for Trump's industrial policy, such as it is Going forward. Joining us today is Jonas Nam. He's an associate professor at the John Hopkins School of Advanced International studies in Washington, D.C. and he was recently senior economist for Industrial strategy at the White House Council of Economic Advisors. He studies industrial policy, supply chains and trade, and he's the author of Collaborative Forging Green Industries in the New Global Economy. Jonas, welcome to Shift Key.
C
Thank you for having me. I'm finally on.
B
You're finally here. We finally got you. So I think let's just start here. What do you make of the ruling today and then the president's kind of successive 10% tariff announcement?
C
I don't think this was surprising. Right. We had during the hearings kind of gotten this impression that the judges were somewhat skeptical, at least of the ability of the president to use AIBA to justify these tariffs. And so I think the surprise was really that it took so long. There were lots of rumors flowing, floating around for the past couple of months that this would come out anytime. And so it finally came. But it sort of came in the form that everyone expected. And the conclusion today was that this is not a tariff statute and that there are other authorities for the president to use to do these things, but this isn't one of them.
B
I feel like the most interesting thing I kind of hinted at this in the intro was that Brett Kavanaugh ruled first of all that the tariffs were legal, which is kind of crazy, but also that he was like, this is not the proper use of the major questions doctrine, a doctrine he invented to constrain executive authority. But that's neither here nor there, which
C
the liberal justices also didn't sign on to. Right. So it was sort of three people saying this is major questions, and then three people saying this is just, you know, illegal.
A
Yes.
B
And I think maybe crucially for this audience, Justice Gorsuch cited disapprovingly the Trump administration's argument that a future president could use ieepa, the statute in question here, to impose tariffs on fossil fuels or internal combustion engines because it considers climate change to be a national security threat. That was like an argument made by President Trump's team on behalf of the tariffs to convey their belief that AIPA convict, like, had this huge economic policy making power within it. And Justice Gorsuch was like, no, no, no, it doesn't let you do that. And it also doesn't let you impose these tariffs on all these other countries. Okay. So I will say I have basically spent every moment up until now not learning about the other tariff authorities. They all are, like, known by A different number, and it always seemed like people were mentioning a new one. So can you walk us through? Just like with IIPA out of the way, what are the other authorities or powers under the law that have been used to impose tariffs on the past or that are seen as kind of being the other powers the President could invoke here if he wanted to keep slapping tariffs on major trading partners.
C
So one of the big advantages of the IEBA path for the administration was that it didn't really involve a lot of procedure and they had a lot of discretion now no more. But at the time thinking that they could do this, they had a lot of discretion about how to do this, who to apply this to, which products to exempt, and how to change it very quickly. And so it was basically fairly unconstrained. And so the other authorities all come with more process and many of them are already in place with more process. So I think one thing to maybe start with is that the IEVA tariffs are only one part of this tariff stack and that different products have other tariffs applied to them already. Some of them stack on top of one another, some of them don't. But there are many kind of authorities in this space that are being used at the same time. The President came out today and said they're going to impose 10% universal tariffs under the section 122, which is from the Trade act of 1974, which is really tough address kind of a large and serious deficit, can be done very immediately, but it's capped at 15%. They said they're going to use 10. The problem for them is that it expires in 150 days unless Congress extends it. So it can sort of stop the revenue loss from taking away the reciprocal and the fentanyl tariffs. It can buy time for permanent fixes, but itself is not really a permanent solution unless there's congressional buy in in 150 days, which seems somewhat unlikely. So that's what they've already decided. They're going to use sort of as the bridge to get to these other authorities. There's another tariff authority called Section 232, which is about national security related issues. And so there you need to have an investigation and then you can impose these tariffs. We have lots of these investigations ongoing. Some of them are already completed. But pharmaceuticals, robotics, chips, I mean there's a bunch of them that are out there. And so what they don't like about this is that you have to have this investigation. So it's not immediate and so it requires a Little bit of process, like
B
a Commerce Department investigation.
C
Right.
B
This is like a. It's like a known process where they.
C
Yeah, and there needs to be a hearing and. Yes, all of those things. So that's 232. And then you have section 301, which is about unfair trade practices, that also requires an investigation and a public hearing. Kind of a common period where industry can weigh in. And so you could use that to recreate these tariffs on a country by country basis. The section 232 tariffs are mostly at the sectoral level. So the investigations are about sectors that have national security implications, although that has also been stretched widely by this administration. We've applied them to kitchen cabinets in this past year. So I don't know, immediately follow the national security implications there. But, you know, there is some leeway there in how this is laid out. Section 301 is about unfair trade practices. And then there are the tariffs that were used, you know, almost 100 years ago after the depression, which is section 338. That gets thrown around a lot. I think it has a lot less procedural constraints attached to it than these other ones. But it's also untested in modern courts. And this would require the administration to prove that there's discrimination against U.S. exports. And you could imagine a lot of litigation around how to define discrimination. And so these are sort of the broad authorities that exist and that the administration has signaled they will rely on. I think mostly the first three.
B
It does seem like, I think one thing hearing this list is that there's five other tariff authorities he could use. And while some of them have restrictions on time or duration or tariff rate, there's actually still a good amount of, like, untested tariff authority out there in the law. And if the president and his administration were like, quite devoted, they would be able to go out there and figure out the limits of 338 or figure out the limits of. Of 301.
C
Yeah, I mean, I think one thing to also think about is what is the purpose of these tariffs? Right. And so I think the justifications from the administration have been varied and changed over time. But, you know, they've taken in a significant amount of revenue, some $30 billion a month from these tariffs. This was about four times as much as in the Biden administration. And so there is some money coming in from this. And so 122. The 10% immediately would bring back some of that revenue that is otherwise lost. One question is, what's going to happen to refunds from the ieba Tariffs, are they going to have to pay this back? It seems like that's also kind of a court battle that needs to be fought out. And the Supreme Court didn't weigh in on that. But the estimates show that if you brought the 122s in at 10%, you would actually recoup a lot of the money that you would otherwise lose. And the effective tariff rate in the US would go back from 10% to about 15%, roughly to where it was before the Supreme Court ruled on it.
B
Has the effect of tariffs from the Trump administration been larger or smaller than what you thought it would be? Not necessarily in the immediate aftermath of Liberation Day, because he announced these giant tariffs and then kind of walked some of them back. But, like, the tariff rate has gone up a lot in the past year. Has the effect of that on the economy been more or less than you expected?
C
I think that the industrial policy justification that they have also used is a completely different bucket. You can use this for revenue, and then you can just sort of tax different sectors at different times, as long as the sum overall is what you want it to be. From an industrial policy perspective, all of this uncertainty is not very helpful. Because if you're thinking about companies making major investment decisions, decisions, and you have this AIPA Supreme Court case sort of hanging over this situation for the past year now, we don't know exactly what they're going to replace it with. But you're making a $10 billion decision to build a new manufacturing plant. You may want to sit that out until you know what exactly the environment is, and also what the environment is for the components that you need to import. Right. So a lot of US Imports actually go into domestic manufacturing. And so it's not just the product that we're trying to kind of compete with by making it domestically, but also the inputs that we need to make that product here that are being affected. And so for those kinds of supply chain rewiring industrial policy decisions, you probably want a lot more certainty than we've had. And so the Supreme Court ruling against the IPA tariff justification is certainly more certainty in all of this. So we've now take that off the list. But we are not clear what the new environment will look like and how long it's going to stick around. And so from sort of an industrial policy perspective, that's not really what you want. Ideally, what you would have is very predictable tariffs that give companies time to become competitive without the competition from abroad, and then also a very credible commitment to taking these tariffs away at some point so that the companies have an incentive to become competitive behind the tariff wall and then compete on their own. That's sort of the ideal case, and we're somewhat far from the ideal case, given the uncertainty, given the lack of clarity on whether these things are going to stick around or not, or might be extended forever, and sort of the politics in the US that make it much harder to take tariffs away than to impose

I have heard from Democrats and like Democratic economic policymaker making staff. Let's say that they really did believe that when Trump announced all these tariffs that what people said it was going to crash the economy and the fact that it like hasn't necessarily crashed the economy has made some of them go, huh? Well, maybe tariffs aren't as bad as we kind of were told they were and we should consider them as part of a broader economic playbook. Looking over the past year, have you been surprised by how resilient the US Economy has been despite all these new trade restrictions that didn't exist two years ago?
C
I think the answer to that question really depends on what you're looking at specifically. If this was supposed to be a manufacturing reshoring tool, in some ways, it's too early to tell whether it'll work. We've seen this during the Biden administration. The Inflation Reduction act came out, and by the time the election rolled around, a lot of these plants were still under construction. So in some ways the theory was still untested on whether that would have changed people's voting behavior because we didn't have enough time. And so in the same way, we don't have enough time now, and we've seen manufacturing job losses over the last year. Things have picked up a little bit recently and sort of capacity utilization is up this month or last month rather in the U.S. but I think that is from using existing plants more rather than building new ones in response to the tariffs. And of course, there are big announcements that have been made where companies that were going to build a plant in Canada are now building it in the US and some changes in decision making have occurred as a result of it. But I think just really judge this as a sort of reshoring manufacturing industrial policy. It's just too early. And I think the uncertainty really also then prolongs the period that it would take for companies to really do this. I mean, you'd want to think about that decision quite carefully. And while a lot of this stuff is still ongoing, I think companies have just avoided making big decisions.
B
It's also unclear to me how much of American trade tariffs actually did fall on in terms of specific bilateral relationships. So to be specific, like we talk about these fentanyl tariffs, which is the President's name for the what he said were 25% tariffs on Canada and Mexico and 10% tariffs on China and 10% tariffs on Canadian energy exports. And those are big numbers. But what wound up happening in the immediate aftermath of his initial decision was that he was that trade previously authorized under usmca, the successor to nafta, was exempted or wasn't fully subject to that tariff. And what that meant is that basically like for instance, no Canadian oil exports have ever been subject to this 10% tariff. It's totally trade as normal between the two countries, at least on an energy basis. And yet notionally on the books, there is a threat of a much higher tariff, I suppose, if the President were to change his mind or in the future.
C
I think you raise a really good point also because the effective tariff rate was around 15 or 16% or so much lower than some of these headline numbers that were being thrown around. And that's because we've exempted a lot of stuff, right? So coffee prices went up and we exempted Brazilian coffee imports. And we've taken other key industries out of this calculation that USMCA compliant goods were exempted from the fentanyl tariffs on Canada and Mexico. And so overall, the sort of number of products that are being impacted are much smaller than everything. And one of the interesting questions, I think now is, for instance, in the section 122, 10% game that they're trying to play, the process for exempting and excluding certain products works differently. And so if this really becomes a universal 10%, then would actually affect a lot of things that currently aren't being tariffed by the reciprocal tariffs. And they don't have a lot of time. So maybe that also plays into it where they don't have the capacity to really plan it out strategically. And so if we're now then moving to a world where a lot of critical inputs into domestic manufacturing are being tariffed at 10% that were previously exempt, that might have some negative consequences for the manufacturers that are trying to survive. And all of this uncertainty, I guess
B
that also removes like a huge opportunity for corruption. Because one thing that would happen is the President would take not only like coffee out of the tariff, one thing that would happen is the president wouldn't only remove tariffs on product categories like coffee, but he would just remove them from companies or put them back on other companies. And it seemed like this huge black box of potential corruption that there just wasn't a lot of visibility into. Let's talk about the sectors that we follow here. So what does this Supreme Court case mean, if anything, for electric vehicles?
C
Maybe before we jump into this, just to remind everyone. So we've taken away one layer of this kind of cake of tariffs that we've built here over time. There's section 301, there's section 232s, there's anti dumping and countervailing duties. Sometimes there are safeguards, Section 201. And so all of those things can apply to the same product. And so we're sort of taking one piece out of that stack, but it means the others are still there.
B
And crucially, this is not like a supermarket sheet cake with two layers or even a pound cake like you might make.
C
That's a fancy cake.
B
It's a Russian honey cake with 12 or 13 layers stacked upon each other of delectable trade find goodness.
C
That's exactly right. And so if we think about EVs, for instance, the European companies actually aren't being tariffed under IPA. They're tariffed under section 232 for autos on parts, which is a totally different legal foundation. And so they are not benefiting from IIPA going away. They might now get hit with 122s on top of what they were paying previously, if that isn't designed carefully. And so there's a lot of open questions about what that actually looks like, looks like in practice, but it's certainly not helping them. On the China side, which is probably our bigger concern is that electric vehicles are already in the section 301 penalty box and they get 100% on EVs, and there's tariffs on batteries under 301. So IEBA was there with 10% for these products, but it wasn't really the significant piece. And so I think there doesn't fundamentally change the landscape. But the problem, I think, is more that we have uncertainty and there's this constant turmoil over what it's going to be. And we have four meetings between C and Trump lined up for the year, and he's supposed to go there at the end of March. And lots of uncertainty sort of in the policy space that AIPA kind of feeds into, but wasn't really that critical, I think. And on China, specifically, the ustr, the Office of the Trade Representative launched in the fall a Section 301 investigation on China, saying that they hadn't adhered to the requirements of the Phase one trade deal from the first Trump administration. They held the public hearings, they probably have a report ready to go so they could reimpose. Also kind of on a national level, 301 tariffs on China, based on this finding, which could more than offset the loss of the IEBA tariffs.
B
Okay, next sector. So what does this mean for solar? Because one interesting thing, subplot here that my colleague Matt Zeitlin was talking about earlier today is that after Liberation Day, Wall street became very convinced that First Solar, this US solar manufacturing firm, was going to be the huge beneficiary of this new Trumpian tariff regime. And it really has not been at all. It's like it turned out that a lot of its inputs had new tariffs on them, that it really didn't affect its business very much. But there are a lot of tariffs on solar. Are they that go back all the way to the Biden administration or the first Trump administration? Were those issued under ipa and what is their current status?
C
Solar was affected by the IEBA layer in China, for instance. But there are other tariffs in place that are much more significant. And then on China and also Southeast Asian suppliers there are anti dumping and countervailing duties in place that are issued to specific companies. And so the rate kind of depends on which company, but some of them are over 200%. So there you might have a loophole that like a new supplier springs up that isn't yet affected by this countervailing duty regime and so they might benefit. But I think there are two. The IEBA story is only one layer. We had Section 201 safeguards on solar that I think were expiring in February this year. So that layer was ending and now AIBA is ending. But Section 301 on China and the AD CVDs remain in place and I think are going to make it unlikely that we see the sudden onslaught of Chinese supply.
B
Are there any other kind of sectors to talk about here? Wind really affected by this or I don't know, data center inputs?
C
Wind I think was exposed to the IPA layer to some degree. But I think the other question is more broadly what are we doing with the domestic wind indicators industry? There's also a 232 national security investigation that is ongoing on wind that they could switch to as a justification both on wind turbines and turbine parts. And so there I think we might see some sort of temporary IPA relief, especially for imports like metals and so on that are now coming in perhaps at different prices. I don't know if that can really help the wind industry overcome the broader headwinds that they're facing with this administration. And but if there is a real positive impact I would expect them to very quickly switch to the 232 justification to make up for it. I think on data centers it's interesting. Data centers import a huge amount of equipment, right? So servers, networking equipment, power distribution, cooling switch. There's all this stuff that goes into a data center and if AIPA went away and nothing replaces it, that might actually be a meaningful relief for a lot of that stack. But now under this 10% 122 surcharge it's coming back. And if some of these exemptions that we had in place for some of these components in order to support domestic data center build out are not included and we have to see how they actually implement this, this could be quite negative. But to me this is really a story at this point of thinking about this way more as a revenue source than a strategic industrial policy that's trying to reshore certain, certain sectors. And the more we change it up and switch from one authority to another, the more it becomes a revenue story, because the actual economic impact in terms of reshoring is going to be less and less.
B
So one thing I'm taking from this conversation is that while clean energy and energy inputs might get some a tiny bit of relief, largely they were already subject to this existing stack of pre existing tariff authorities under other laws. And so they might benefit from like some economic tailwinds from this. But it's not like Chinese or Southeast Asian solar panels are going to suddenly be available in the United States at cost. Stepping back then, what is your read of how this ruling fits into the Trump administration's trade policy? And I think broadly America's attempt to formulate some kind of industrial policy that now started with the first Trump administration was continued and changed by the Biden administration and now soldiers on under the second Trump administration.
C
If I think about this broadly in terms of sort of economic policymaking, the tariffs are one tool you can use to shape the nature and structure and composition of the domestic economy in many ways. What I think is much more important is what do you do behind the tariff wall to really help companies build competitive manufacturing capacity, for instance? Right. And the tariffs themselves are not really enough to do much there. And a lot of the incentives and sort of support that, for instance, the Inflation Reduction act included have been taken away or it's shortened significantly. And so we're doing kind of less on the domestic economy and we're doing more at the border. But I think ideally you would do much more certainty at the border and then combine it with a domestic strategy. And I think we're seeing some of this now happen kind of in the critical mineral space vault forge all these kinds of new initiatives that are being pushed out by the administration to look at the demand side and kind of create more stable markets for these technologies, for instance. So slow beginnings of kind of the supply side and demand side match and pairing different industrial policy tools. But in some ways, I think this tariff game has been a huge distraction from the actual work that we need to do on vocational training, on financing for manufacturing, on creating stable demand for these technologies that we want to make domestically so that companies can get financing and invest. And so looking at trade policy in that kind of broader picture, it looks more like a revenue policy than an industrial policy because it's not really coordinated with these other elements.

Episode: What the Supreme Court’s Tariff Ruling Means for the Energy Transition
Date: February 21, 2026
Host: Robinson Meyer (Executive Editor, Heatmap News)
Guest: Jonas Nam (Associate Professor, Johns Hopkins SAIS; former Senior Economist, White House Council of Economic Advisors)
Theme: Analyzing the Supreme Court’s landmark decision on President Trump’s tariffs and its implications for the clean energy sector, industrial policy, and the future of U.S. trade authority.
This emergency episode dives into the Supreme Court's striking down of President Trump's aggressive tariffs imposed under the International Emergency Economic Powers Act (IEEPA). Robinson Meyer is joined by industrial policy and trade expert Jonas Nam to interpret the repercussions for America’s energy transition, clean technology supply chains, and broader economic policy. The discussion breaks down alternative presidential tariff powers, sectoral impacts (EVs, solar, wind, data centers), and what this precedential ruling signals for the future of industrial and trade policy in the U.S.
Ruling Summary ([01:25 – 04:10])
Political Dynamics & Dissent
Immediate Impact
Jonas Nam explains the “layer cake” of U.S. tariff law:
Why IEEPA Was Used ([06:00])
Alternatives to IEEPA ([06:30 – 09:41]):
Overall Picture
Revenue vs. Industrial Strategy ([10:17 – 13:52])
Democrats' Evolving View on Tariffs ([15:26])
Assessment of Outcomes So Far ([16:04])
Reality vs Headline Tariffs ([17:27 – 19:50])
Risks Ahead
On the administrative complexity of tariff powers:
On the ruling’s chilling effect for industrial investment:
On the mismatch between policy intent and real-world effect:
The Supreme Court’s decision narrows presidential flexibility for sweeping tariff action, but leaves open a multitude of other tools—each with process and constraints—that can shape U.S. trade and industrial policy. The net effect for the clean energy transition is modest, as multiple concurrent tariff layers persist. The ruling does little to clear commercial uncertainty or systematically advance domestic manufacturing; it underscores the urgent need for a coordinated, strategic, and certain industrial policy beyond border taxes if the U.S. is to lead the energy transition.
Guest Jonas Nam’s final word:
“Trade policy looks more like a revenue policy than an industrial policy because it’s not really coordinated with these other elements.” ([28:45])
