Robinson Meyer:
[1:25] Hi, I’m Robinson Meyer, the founding executive editor of Heatmap News. It is Friday, February 20. 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 IEEPA, 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. It was a bit of a stitched together decision. Clarence Thomas, Samuel Alito, and Brett Kavanaugh dissented, while Neil Gorsuch, Amy Coney Barrett, and the chief justice ruled with the liberals, although the liberals only concurred with some of the decision. But it takes away a major tool of economic and diplomatic policy making for President Trump.
Robinson Meyer:
[2:12] There were really two sets of tariffs affected by this decision. One was a set of so-called 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.
Robinson Meyer:
[2:53] Joining us today is Jonas Nahm. 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 Advantage: Forging Green Industries in the New Global Economy. Jonas, welcome to Shift Key.
Jonas Nahm:
[3:18] Thank you for having me. I’m finally on.
Robinson Meyer:
[3:20] 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?
Jonas Nahm:
[3:33] 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 IEEPA to justify these tariffs. And so I think the surprise was really that it took so long. There were lots of rumors floating around for the past couple of months that this would come out any time. 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.
Robinson Meyer:
[4:09] 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.
Jonas Nahm:
[4:28] Which 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.
Robinson Meyer:
[4:39] Yes. 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 IEEPA had this huge economic policymaking 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. OK, 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 IEEPA out of the way, what are the other things? 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?
Jonas Nahm:
[6:00] So one of the big advantages of the IEEPA 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 IEEPA 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.
Jonas Nahm:
[6:51] 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 to address kind of a large and serious deficit, it 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.
Jonas Nahm:
[7:40] 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. it. And so it requires a little bit of process.
Robinson Meyer:
[8:11] Like a Commerce Department investigation, right? This is like a, it’s like a known process where they...
Jonas Nahm:
[8:18] 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 tears 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 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
Jonas Nahm:
[9:38] has signaled they will rely on. I think mostly the first three.
Robinson Meyer:
[9:41] 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?
Jonas Nahm:
[10:17] 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 dollars 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 IEEPA 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, you know, the estimates show that if you brought the 122 in at 10%, you would actually recoup a lot of the money that you would otherwise lose and the effective tariff rate in the U.S. Would go back from 10% to about 15%, roughly to where it was before the Supreme Court ruled on it.
Robinson Meyer:
[11:18] 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?
Jonas Nahm:
[11:43] I think that the industrial policy justification that they have also used is a completely different bucket. Right. So 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 and you have this IEEPA Supreme Court case sort of hanging over the 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 U.S. 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.
Jonas Nahm:
[12:38] 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 IEEPA tariff justification is certainly more certainty in all of this. So we’ve now taken 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 U.S. that make it much harder to take tariffs away than to impose them.
Robinson Meyer:
[15:26] 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 U.S. economy has been despite all these new trade restrictions that didn’t exist two years ago?
Jonas Nahm:
[16:04] I think the answer to that question really depends on what you’re looking at specifically, right? So 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
Jonas Nahm:
[16:28] 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 U.S.. And some changes in decision-making have occurred as a result of it. But I think to really judge this as a sort of reassuring 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.
Robinson Meyer:
[17:27] 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 what he said were 25% tariffs on Canada and Mexico and 10% tariffs on China and 10% tariffs on Canadian energy exports. And what, Those are big numbers, but what wound up happening in the immediate aftermath of his initial decision 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, 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. But 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.
Jonas Nahm:
[18:31] 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. And 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%, it 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.
Robinson Meyer:
[19:49] I guess 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.
Robinson Meyer:
[20:17] Let’s talk about the sectors that we follow here. So what does this Supreme Court case mean, if anything, for electric vehicles?
Jonas Nahm:
[20:28] 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’s 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.
Robinson Meyer:
[20:52] And crucially, this is not like a supermarket sheet cake with two layers or even a pound cake like you might.
Jonas Nahm:
[20:59] Make at home. No, it’s a fancy cake.
Robinson Meyer:
[21:00] It’s a Russian honey cake with 12 or 13 layers stacked upon each other of delectable trade-fine goodness.
Jonas Nahm:
[21:09] That’s exactly right. And so if we think about EVs, for instance, the European companies actually aren’t being tariffed under IEEPA. They’re tariffed under Section 232 for autos and parts, which is a totally different legal foundation. And so they are not benefiting from IEEPA 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 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 IEEPA was there with 10% for these products, but it wasn’t really the significant piece. And so I think there it 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 Xi 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 IEEPA kind of feeds into, but wasn’t really that critical, I think.
Jonas Nahm:
[22:23] And on China specifically, the U.S.TR, 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 Aiba tariffs.
Robinson Meyer:
[22:53] Okay, next sector. So what does this mean for solar? Because one interesting 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 U.S. 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 IEEPA? And what is their current status?
Jonas Nahm:
[23:36] Solar was affected by the IEEPA 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 IEEPA 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 IEEPA is ending. But Section 301 on China and the ADECVDs remain in place and I think are going
Jonas Nahm:
[24:26] to make it unlikely that we see the sudden onslaught of Chinese supply.
Robinson Meyer:
[24:30] Are there any other kind of sectors to talk about here, you know, really affected by this or, I don’t know, data center inputs?
Jonas Nahm:
[24:41] Wind, I think, was exposed to the IEEPA layer to some degree, but I think the other question is more broadly, what are we doing with the domestic wind 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 IEEPA relief, especially for inputs 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. But, you know, 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.
Jonas Nahm:
[25:29] 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 IEEPA 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 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.
Robinson Meyer:
[26:22] So one thing I’m taking from this conversation is that while clean energy and energy inputs might get 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
Robinson Meyer:
[26:50] 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.
Jonas Nahm:
[27:19] 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, that 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
Jonas Nahm:
[28:08] 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, you know, 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 in 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.
Robinson Meyer:
[29:05] I think we’ll have to leave it there. Jonas Nahm, thank you so much.

Trump’s new tariffs seem to make few exemptions for clean energy.
Is this how a new wave of inflation starts?
The international crude oil benchmark leapt to $100 a barrel on Thursday, its highest level since May. The surge came after the Iran-backed Houthi group in Yemen attacked two Saudi oil tankers in the Red Sea.
Those strikes pinched one of the remaining fossil-fuel export routes from the Arabian Peninsula, but they also revealed new constraints on President Trump’s Iran strategy. Throughout most of the spring, the president was able to keep a lid on oil prices by vowing to end the war that he started — and when he said he wanted a ceasefire, investors believed him. Now the White House is running out of options to end the conflict, and the president may be losing his ability to jawbone prices lower.
Now, these high prices haven’t quite hit in America yet. The U.S. oil benchmark, West Texas Intermediate, stands at $92, having increased 25% over the past month. But gasoline and diesel prices are rising fast. And in any case, Americans may be about to deal with a new one-time price hike from another source: tariffs.
The Office of the U.S. Trade Representative announced a new array of global tariffs on Thursday afternoon; the government will start levying 10% to 12.5% taxes on most imports from more than 80 countries tonight. (By the Trump administration’s own reckoning, these countries supply 99.4% of America’s imports.) The new tariff regime, which is allegedly designed to withstand the Supreme Court’s scrutiny, has some crucial exemptions, including drugs, cars, phones, planes, semiconductors, and oil and natural gas.
But it will fall heavily on goods and exporters that supply electricity and clean energy inputs to the United States. I’d love to be wrong, but on my initial read, solar panels, lithium-ion batteries, inverters, motors, and other power equipment are all covered by these new tariffs (to name a few categories). These new taxes will stack on top of the existing anti-dumping tariffs that already apply to, say, Southeast Asia-made solar panels. You have to squint for silver lining here, but perhaps there’s an upside for manufacturers: These additional tariffs won’t apply to the “critical mineral” inputs that they rely on to make some of these technologies in the U.S. Most transformers also seem to be exempt because they’re already covered under an earlier tariff regime. Alas, many other goods that manufacturers do need — such as factory equipment — will face the new levies.
The United States economy is resilient; it looked through the spring’s run-up in oil prices as well as Trump’s earlier round of trade levies. (I’m half-convinced that tariffs are likely to outlive the Trump administration, no matter what happens in the next few months, because the federal government would otherwise be starved of revenue without them.) But as my colleague Matthew Zeitlin wrote last week, we know the U.S. energy system is already wheezing under current price levels. A new surge in oil prices, a price hike for renewable energy inputs, and a continued surge in electricity demand do not set us up for a beautiful macroeconomic outcome.
The company’s latest sustainability report, shared exclusively with Heatmap, shows that carbon intensity per kilometer traveled has dropped 81% since 2019.
Lime, the electric scooter and bike-sharing company that recently raised $174 million in its initial public offering, estimates that it replaced 38 million car trips across the globe last year. Even as it helped prevent substantial vehicle pollution, though, Lime racked up about 90,000 metric tons of carbon emissions tied to its own activities.
While that number pales in comparison to the tens of millions of tons of carbon that tech companies like Microsoft and Google emit, or the hundreds of millions of tons that traditional car companies like Ford report, the point stands: Even companies producing solutions to climate change have emissions to deal with.
For such a small player, Lime has made quite a bit of progress reducing its climate impact. Since 2019, when Lime first began tracking its carbon footprint, the number of kilometers traveled by Lime’s bikes and scooters each year has grown nearly 250%, while the carbon intensity of each kilometer has decreased by 81%. All in all, Lime has reduced its total reported emissions from direct and indirect sources by 35%. The company made much of that progress in just the past two years.
According to Lime’s latest sustainability report, shared exclusively with Heatmap, its biggest recent strides came from doing something that is generally considered to be pretty difficult: It decarbonized part of its supply chain.
Most of the emissions related to Lime’s business come from activities that are not within the company’s control. Its biggest source has always been the manufacture of the vehicles and batteries it uses, and more specifically from the manufacture of aluminum, which requires a huge amount of electricity to smelt.
Lime doesn’t manufacture its own vehicles, so it had to convince its partners to find and use lower-carbon metals and batteries. “One of the strategic advantages we have is that we design our own vehicles. We’re not buying them off the shelf,” Andrew Savage, Lime’s vice president of sustainability, told me. “So we don’t own the manufacturing, but we have a large amount of input and ability to work with suppliers to modify a supply chain.”
Savage said that a significant sourcing effort in 2024 paid off in 2025, when the company increased the amount of aluminum in its products that was made using renewable electricity and sourced more batteries made with renewable power. That combination of efforts cut the company’s total capital goods-related emissions in half compared to the previous year, and reduced the carbon intensity of each Lime vehicle by more than 25%. It also didn’t cost too much, Savage told me, adding that the expenditure was “marginal enough that it has made sense for us.”
Lime has also invested in its repair capabilities, which allows the company to keep its vehicles and parts in circulation much longer and avoid buying as many new ones. This has helped to keep emissions down even as its business has grown.
Another major source of emissions for Lime is shipping and logistics — again, a part of the business that is somewhat out of its hands. Lime hires third parties to pick up its bikes and scooters from major ports, transport them to regional hubs, and then distribute them to the markets where it operates. Initially, the vehicles were transported in trucks fueled by diesel. In 2024, Lime found partners that would be able to pick up its cargo at the ports of Los Angeles and Long Beach and bring them to its logistics hubs in electric drayage trucks.
The company made similar moves throughout its European business, transitioning most of its port-to-hub shipments to trucks running on a bio-based diesel fuel called HVO100, which is made from used cooking oil and other waste oils and estimated to reduce emissions by 89% compared to conventional diesel. This past year, Lime expanded its use of HVO100-fueled trucking partners to cover shipments from hubs to 16 cities.
The problem with HVO100, according to Nikita Pavlenko, the program director for fuels and aviation at the International Council on Clean Transportation, is that there will never be enough of it to fully decarbonize heavy duty trucking. “Particularly in Europe, where the transport sector is more reliant on diesel, it could never feasibly be met with waste oils entirely,” he told me. Purpose-grown crops like palm and soy could meet the increased demand for bio-based diesel, but that starts to come at the expense of land-use emissions and deforestation.
Savage was well aware of the limitations, and told me he views HVO100 as an interim solution. “We looked across Europe and somewhat shockingly found very few options on the electrification side,” he said. Even a country like Norway, which is famous for its adoption of electric vehicles, does not yet have much in the way of electric trucking and logistics, he said. “But it’s something that we absolutely expect to come in as part of our decarbonization roadmap.”
Interestingly, Lime reported that its upstream shipping and logistics emissions slightly increased in 2025 compared to 2024, although the company has cut this category in half overall since 2019. Lime attributed this to an increased use of expedited shipping for certain parts last year, but said its increased use of EVs and HVO100 helped mitigate the impacts.
Lime currently operates on five continents and in 230 cities. While it’s made some progress on low-carbon shipping within the EU and U.S., there’s still Australia, South America, and Asia to figure out. Looking ahead to next year, Savage said he wants to expand the number of markets and the amount of goods the company moves using lower-carbon vehicles. He also wants to augment the company’s repair practice.
“We view the work we’re doing on decarbonizing the business as going completely hand in hand with our mission and objective as a company,” Savage said. “It’s not a sideshow.”
A new 60-home pilot program aims to expand vehicle-to-grid charging.
When energy experts imagine the grid of the future, they often dream of millions of electric vehicles moonlighting as mobile power banks, using their hefty batteries to send electricity back to the grid when it needs a boost. But despite rapid EV adoption, this utopia has remained largely out of reach. Most vehicles don’t yet support bidirectional power flow, and most markets lack incentives for customers to feed power back to the grid in the first place.
That’s finally starting to change. While vehicle-to-grid — a.k.a. V2G — technology is still in its earliest innings, a new Massachusetts program announced on Thursday is working to make the technology something closer to commonplace. Funded by the Massachusetts Clean Energy Center, the state’s economic development agency, the initiative will install 60 bidirectional charging systems in participating residents’ homes.
The program has already begun enrolling its first participants, joining a small but growing group of V2G demonstrations across the country. But the field remains so nascent that even a 60-home project stands out. Kip Hack, who leads the distributed energy resource management company EnergyHub’s EV work, told me he very much considers it a “leading program for North America.”
The Massachusetts initiative brings together a wide variety of partners: utility companies Eversource and National Grid, EnergyHub, and technology partners Sunrun and The Mobility House, which each provide the software and device integrations needed to connect various EV models to the grid. Depending on their vehicle, eligible customers will enroll in the program through either Sunrun or The Mobility House, which will then connect them to their utility’s existing demand flexibility program, ConnectedSolutions. This decade-old initiative pays customers to reduce strain on the grid by leveraging smart thermostats, batteries, and other commercial and industrial energy systems. Now EVs will join the mix.
“They don’t actually care what the participating technology is. They only care about the output,” EnergyHub’s president, Seth Frader-Thompson told me, referring to ConnectedSolutions’ technology-agnostic design, which runs on EnergyHub’s software platform. That means the program can readily incorporate new distributed energy resources as they become available, simplifying the entire process in a way that many other regions have yet to figure out. “So when V2G technology was ready, nobody had to create a new program. You already had a program structure, an incentive structure, et cetera, that you could just have these vehicles participate in.”
Each distributed energy asset enrolled in the program can earn up to $275 per average kilowatt of grid support provided during the summer months. But customers don’t receive that payment directly from their utility. Rather Sunrun and The Mobility House set their own customer incentive structures based on that underlying $275 per kilowatt value.
Chip Silverman, Sunrun’s director of grid services and virtual power plants, told me that its customers will receive a fixed payment simply for signing up, just as the company’s stationary battery storage customers do. That gets new participants in the door — they can then earn additional performance incentives if they actually discharge power back to the grid during a demand response event. “We want to incentivize people to plug in 5:00 p.m. to 8:00 p.m. on weeknights because we want to get you to try to hit the peak events whenever possible,” Silverman told me.
The pool of qualifying vehicles remains quite limited, however. Sunrun’s system only supports the Ford F-150 Lightning, while The Mobility House’s software integrates with chargers compatible with the Kia EV9, Volvo XC90, Polestar 3, and several Nissan Leaf models. Teslas with V2G capability — which today means just the Cybertruck — are not eligible. That’s because while every other vehicle in this program places the requisite DC to AC power converter within the wall charger, Tesla installs this hardware in the car itself. While that will likely prove to be a smarter, cheaper long-term approach, for now it doesn’t align with how utilities certify and approve grid-connected equipment.
Yet even at this early stage, with limited scale and narrow eligibility requirements, Massachusetts’ early adopters are already demonstrating the technology’s value. “It has been quite hot, unseasonably hot in New England these last several weeks,” Hack told me, explaining that participants’ EV batteries have already been tapped to discharge power “more than once” since enrollment began earlier this month.
The potential for far greater impact is enormous. “The size of the battery in the car is remarkable,” Frader-Thompson told me. While a typical home battery stores around 10 to 15 kilowatt-hours of energy, an EV battery can hold on the order of 70 to 100 kilowatt-hours. “So if the vehicle is plugged in, it essentially has the ability to export the equivalent of an entire residential battery every hour during an event,” he explained.
To truly turn V2G from a promising concept into a reliable grid resource, however, utilities and grid operators will need much more data on when these batteries are available and how much power EV owners are actually willing to provide. By the end of this summer, Massachusetts’ latest experiment could offer some of the first real-world answers.
