Robinson Meyer:
[1:26] Hi, I’m Robinson Meyer, and you are listening to Shift Key, Heatmap’s podcast about decarbonization and the shift away from fossil fuels. It is Monday, March 2. Over the weekend, the United States and Israel launched a new war on Iran, killing its Supreme Leader and bombing hundreds of targets across the country. The war is a big deal for the United States, for Iran, for the Middle East, and for the global economy. And even though it was preceded by the largest buildup of U.S. military equipment in the region since 2003, it was still, in a way, surprising. There hasn’t really been any effort to sell the war to the American people. It’s still not clear that it was legal or constitutional. And President Trump has been hazy about his goals for the conflict.
Robinson Meyer:
[2:06] For our purposes, though, here at Shift Key, the war is going to have big implications for the world’s energy markets in the short term and the long term. Like all geopolitical shocks, it is going to shape how countries make decisions about energy long after this particular conflict ends. And the longer this conflict goes, the deeper its consequences could be. So for today’s episode of Shift Key, I wanted to get our bearings on this new war and what it could mean. Our guest today is Gregory Brew. He’s an analyst with the Eurasia Group’s energy, climate, and resources team, focusing on the geopolitics of oil and gas. He serves as the group’s country analyst for Iran. And he’s an historian of modern Iran, oil and U.S. foreign policy, as well as the author of two books about the subject. He’s going to walk us through what has happened so far, just how long this conflict could go on and what it will mean for energy. Greg, welcome to Shift Key.
Gregory Brew:
[2:56] Thanks for having me on.
Robinson Meyer:
[2:58] Can you start by giving us a macro picture of what has happened over the past 72 hours at this point?
Gregory Brew:
[3:05] Sure thing.
Gregory Brew:
[3:08] Early Saturday morning local time, so late in the evening on Friday night here in the United States, the U.S. and Israel launched a significant military operation against Iran. In the past 48 hours, the U.S. and Israel have bombed probably more than a thousand targets inside Iran. These are mostly military targets. Iran’s ballistic missiles, elements of its military infrastructure inside the country, its navy, its naval assets close to the Persian Gulf, all have come under significant fire. In addition, Israel has specifically targeted members of Iran’s leadership. Supreme Leader Ali Khamenei is confirmed dead. Other members of the leadership have also been assassinated. There are other members that their fates remain unknown. In response, Iran has fired a large number of missiles and drones at U.S. bases, at Israel. Somewhat surprisingly, however, many of Iran’s missiles and drones are being fired at Gulf Arab states. The UAE has come under intense bombardment. Bahrain, Saudi Arabia, Kuwait, even Oman, which is a state that’s pretty friendly to Iran, and Qatar all have come under attack from Iran’s drones and missiles. The impact to energy so far, Iran kind of informally declared the Strait of Hormuz closed in the first 12 hours of the conflict.
Gregory Brew:
[4:19] This hasn’t really been followed up with any official action. There haven’t really been many tanker attacks by Iran, but tanker traffic through the strait has come to an almost complete halt. Oil tankers, LNG tankers, tankers carrying refined products, most of them have kind of frozen in place as they await for some clarity as to the situation and as to the risk. Oil prices rose sharply. Sunday night when markets opened, the price of oil went up from about $73 a barrel to about $80 a barrel. Then it fell slightly. It’s at around $78, $79 now. Equally important, I think natural gas prices have increased sharply in various regional markets. The price of natural gas in Europe shot up dramatically today on news that Qatar was going to be shutting off gas production. That’s how the energy story has kind of played out. I should note at the time we’re recording, the war is still ongoing. U.S. and Israel still bombing Iran. Iran is still firing back. Doesn’t look to be concluding anytime soon.
Robinson Meyer:
[5:13] I want to get to the energy picture in a second, but let’s talk about what has happened as far as we can tell from the places that have been bombed from the kind of targets that have been chosen by the U.S. and Israel. Do we have a sense of what their goals are here?
Gregory Brew:
[5:28] We have a sense. I’ll say that. The president has made a number of addresses to the nation where he frames this operation in two ways. One, this is the U.S. and Israel using military power to significantly reduce the threat that Iran poses to U.S. interests, to U.S. bases, and to U.S. allies. In the run-up to this war, there was a lot of attention being paid to Iran’s nuclear program. That program was mostly destroyed in the war of last June, although elements of it remain. However, there were quite a few comments from U.S. officials and a lot being said in private, which suggested that the key U.S. and Israeli concern was not Iran’s nuclear program, but its stockpile of ballistic missiles. Iran is in kind of an interesting state as far as its military. It’s been under sanction for so long. Its ability to build up a conventional
Gregory Brew:
[6:16] military has been pretty curtailed. Like it doesn’t have advanced jet fighters. It doesn’t have a lot of advanced sophisticated military hardware. Where its military is kind of inferior as far as the region is concerned. What it does have, what it’s spent a lot of money, a lot of time and a lot of resources on, is developing a large number of advanced ballistic missiles. And so that’s been, I would say, the single largest focus of the operation. Israel and the U.S. taking aim at Iran’s missiles, trying to blow them up, trying to blow up the factories where these missiles are made, the stockpiles where the missiles are kept, the launchers that Iran uses. That’s the sort of military goal. Trump has been talking about regime change.
Gregory Brew:
[6:53] But the way he’s been framing it is interesting. He says that the U.S. supports regime change in Iran, but that it has to come through the actions of the Iranian people, that the U.S. won’t put boots on the ground, that there’s not going to be a ground invasion of Iran. So I think right now, I think the goal for the U.S. is somewhat open ended. I think they’re going to continue to bomb Iran so long as they see means to do so to keep degrading it to keep damaging it. If that ends with a new regime, great. But at the end of the day, so long as Iran is significantly weakened. And as so long as the threat that Iran poses to the U.S. and the region and to Israel has been significantly reduced, I think that’s enough of a win for at least the president to claim victory.
Robinson Meyer:
[7:30] What would that mean for Iran to be as a state that would have no more military, that basically lost its entire elite and senior leadership structure and has faced these large protests? Like, do we have any sense of what this would mean for the Iranian people?
Gregory Brew:
[7:49] Well, for the Iranian people, nothing good in the short term. Any kind of war puts immense strain on a country, on a people, on a society. We saw that in the war of June of last year. I talked to people in Iran quite frequently. And apart from the political sense, the sense of anger at the regime, the discontent that’s widespread at this point, there was a lot of trauma from the experience of being bombed for two weeks. And right now they’re being bombed not only by Israel, but by the global superpower, the United States. And it’s a campaign of bombing that doesn’t appear to be coming to an end anytime soon. This is going to do additional damage to Iran’s economy.
Gregory Brew:
[8:26] As far as the regime is concerned, there were plans that had been put in place even last June during the war with Israel to manage in the event of Khamenei’s sudden death by decapitation or assassination strike. So his death has not been a body blow to the regime leadership. There’s already a process that’s in motion to pick a new supreme leader. They’re likely to pick one in the coming days, they appear to be doing so quite quickly. That is their way of signaling that, hey, nothing’s going to change from this, right? Regime’s not going anywhere, the Islamic Republic will continue to stand tall. If Trump sees victory in blowing up most of Iran’s military, the Islamic Republic will see victory in surviving that conflict. So long as they emerge with their position more or less intact, which they’re likely to do. What we saw in January was a regime that has no compunction about using lethal force against its own people. The security forces are still in their control. The police are still in their control. The army hasn’t revolted. The leadership hasn’t cracked. So long as that remains the case, I think this war ends with the Islamic Republic still standing,
Gregory Brew:
[9:26] more or less, but in heavily battered form.
Robinson Meyer:
[9:29] Do we have any sense of how this ends on the U.S. side?
Gregory Brew:
[9:34] I think this ends when Trump decides it ends. Right now, there have been some recent comments from the president that sound defiant, that sound resistant to bringing the war to an end. I would hesitate to say, however, whether this administration wants this war to go on for more than a few weeks, right? A longer war keeps oil prices high. A longer war threatens further damage to the U.S. position in the region. Iranian missiles and drones are getting through. They are causing damage, not only to the U.S. bases, but to GCC states. And there’s only so long that the Saudis, the Emiratis, the Qataris are going to want to continue to be hit by Iranian drones. They’re going to want this war to end fairly quickly. As for Trump, if you look at past experience, the wars that he’s been able to deliver, the military interventions that he’s carried out and been able to frame as wins have been short. They’ve been decisive. They haven’t turned into prolonged conflicts. And I think that’s where his head is going to be, try to pull a victory out of something that lasts only a week or two. But right now, he’s signaling that he’s willing to go the distance. Part of that is in response to the Iranians, because the Iranians are treating this like a battle of wills. We can go longer than you, we can keep shooting, we can take the hit. But so long as we continue to cause damage and pain to you, it’s going to be in your interest to wrap this up sooner rather than later.
Robinson Meyer:
[10:46] It’s interesting because there’s two different Trumpian instincts here, or two different Trumpian tendencies. The first is to basically push through with a policy until he reverses it. And a longtime political strength of Trump’s has been that he can reverse any policy at the drop of a hat. And there’s no embarrassment, there’s no shame, that policy is over, and we move on.
Robinson Meyer:
[11:12] And the second, the second tendency here is that, as you were saying, he hasn’t been afraid to break norms, right? And we saw this at the end of his first term with the assassination of Soleimani in Iraq. We saw this term with the operation of Venezuela. And in Venezuela, there was a sense that, oh, my gosh, is the U.S. Now involved in a Latin American country? Are we involved in a process of regime change? And it turned out no, because seemingly they had already back-channeled with Delcy Rodriguez and she was going to be basically a U.S. puppet in the new kind of quasi-regime that emerged. But here it doesn’t seem like there is either a – if they had a goal, they’ve already accomplished it, which is decapitating the Supreme Leader. And if they had a kind of a back channeled puppet leader to put in charge of the country, Trump actually said yesterday that their second or third choices to lead the country had been killed in these military strikes. And so he didn’t have like a candidate. Now, of course, he wouldn’t reveal this, but he didn’t have some kind of candidate ready to go to take over Iran, who could then deal with the U.S. and be addressed to by the U.S.
Gregory Brew:
[12:23] Yeah, so I think the president is putting out a lot of different narratives around this, as far as what the U.S. goal is, whether it is meant to collapse the regime. I mean, he’s been saying things like, the IRGC will surrender, they’ll hand their weapons over to the people, which is a really nice idea. But it’s very difficult to see that happening in reality. It’s very difficult to see how that would happen. A Venezuela style transition is somewhat more plausible, or it could have been somewhat more plausible. But only really in a scenario where the U.S. and Israel deescalate following the assassination of Khamenei and they’re not doing that. They’re continuing to bomb Iran. They’re maintaining the pressure. Whether the United States is communicating with members of the Iranian leadership is beyond me. I couldn’t speculate as to that. I do see it as being plausible that they’re communicating to the Iranians, if you want this to stop, give up X, Y, and Z. We’ll keep doing this unless you surrender, unless you capitulate. And the Iranians are going to have a very strong sense to not do that. Expecting them to surrender misreads the Iranians, both in terms of their position, but also in terms of their ideology and their characteristics. They’re not going to back down.
Robinson Meyer:
[13:26] Can you walk us through some scenarios here? So what would a 10-day, I think there’s been some reference from the president, from others, that this could be a 10-day campaign. There’s been other timeframes that are thrown around. We’re going to get to them. But what would a 10-day campaign here look like, given that I guess we’re already on day three?
Gregory Brew:
[13:45] Yeah, we’re on day three. So the opening salvos included the most significant targets in Iran’s military. Its navy was heavily targeted in the opening days of the strikes. Obviously, Khamenei was hit first. I think he may very well have been the first target. There’s been some reporting to suggest that the Israelis decided to move forward the timeline of strikes because they saw an opportunity to strike at Khamenei, who is generally a fairly elusive figure. He spends a lot of time in secure locations. In this instance, he was at his residence. It was daylight, he was exposed, and they decided to go. This expanding over the next week, you know, the Americans, the Israelis could continue to strike at missile facilities, a lot of these facilities are hardened, they could keep the fight going so that they can get the Iranians to deploy their missiles so that the missiles can be destroyed in the air or on the ground. I think some of this will start to look a little bit like a war of attrition. By the end of the week, that’s probably how the Iranians are thinking about it. They’re shifting or likely will shift from firing lots of missiles to firing lots of drones, which they can do so more easily.
Gregory Brew:
[14:41] They have a lot more of them. They have somewhere in the realm or had somewhere in the realm of 2,000 short range and 2,000 medium range ballistic missiles when the war began, they have thousands of drones, and they can keep firing them in large numbers. So if the Iranian goal is to impose pain and cost to the U.S. to force them to deescalate, then the Iranians will keep shooting at GCC targets at U.S. bases and at Israel, so long as they can. For the Americans after 10 days, they probably will have done as much damage as they could do to Iran’s capabilities. Israel has also targeted internal security forces, police, the Basij paramilitaries that the regime uses to put down dissent. Again, I don’t know if the operation is actually aiming at regime change, but hitting targets like this will undermine the regime, will weaken its control on Iran’s internal security, will cause Iran to exit this conflict in a weakened state. That serves Israel’s interests, even if it doesn’t end up with the regime collapsing. I would expect more strikes like those in the days to come.
Robinson Meyer:
[15:36] Last question, and then we’ll move to energy, which is ostensibly the topic we’re talking about. What would a five-week campaign look like? Briefly, because that’s the other time frame I think we’ve heard from the president.
Gregory Brew:
[15:49] Yeah. I mean, a campaign could last five weeks. I don’t know if it maintains the same level of intensity because they will start to run low on targets. A five week campaign would likely involve more strikes on internal security forces, on leadership, on the apparatus of the regime. I think a five week campaign would be more geared around making the Islamic Republic’s position inside Iran untenable, either creating the environment for protests, creating the environment for internal fracturing, so that you get some kind of shift in the leadership towards individuals who are willing to capitulate, who are willing to come to terms with the United States. That’s, I think, what a five-week campaign would look like. But I also think a five-week campaign wouldn’t be carried on with the same level of intensity. The U.S. would continue strikes, probably at a lower rate. It would look, again, a little bit more like a war of attrition with the Iranians continuing to shoot back as far as they are able. The problem with a five-week campaign for me is that the political costs to Trump mount the longer this war continues, right? It keeps oil prices high, keeps energy prices high, the risk of U.S. casualties, the risk of damage. The longer he goes without pulling a win out of this, I think the weaker he looks.
Robinson Meyer:
[18:28] Something I’ve been thinking about is that the U.S. posture during this war, which is kind of all tactics, no strategy, is kind of derived from Israeli military approaches. But there was no effort to build up a constituency in the U.S. for this war. There’s no sense of existential risk like there is in Israel, around Iran, in the U.S., around Iran. And so ... to some degree, there are Israeli tactics and there is an Israeli posture that’s being borrowed for U.S. operations in this conflict. But there’s none of the domestic politics that makes that possible in the U.S.
Gregory Brew:
[19:07] Yeah, I mean, absolutely. Iran matters a great deal more to Israel than Iran matters to the United States, insofar as Iran matters to the United States. I do think, though, it needs to be remembered that the U.S. is committed to maintaining its position in military hegemony in the Middle East. And Iran is a threat to that position. It’s a threat to U.S. bases in the region. It’s a threat to U.S. partners in the Gulf. It’s obviously a threat to Israel. And Israel is a close U.S. ally. This is a relationship that’s come under political pressure lately. But as far as strategic cooperation, as far as the alignment of interests,
Gregory Brew:
[19:40] when Israel and the United States look at the region, they tend to have very, very similar views. And a key aspect of that view is Iran is a threat. So as far as the approach to Iran using military force, there has been a shift in the last two years. Some of that is Iran’s own doing. Iran chose to escalate in April of 2024 when it launched hundreds of missiles and drones at Israel for the first time ever. It was signaling that it was now willing to take direct military action against Israel. Israel responded by taking direct military action against Iran, and it has not gone well for the Iranians. In that sense, Trump is going further than any U.S. president has in the past. And he is following Israel’s lead to some extent. But I would hesitate to draw too much to say that there’s too much space between the Israeli and American positions as far as viewing Iran, viewing the region strategically. But certainly politically, no one in the country, no one in the U.S. is telling Trump a war with Iran is a national priority. A war with Iran is how you’re going to get your poll numbers up. A war with Iran is how we’re going to win the midterms. That does put constraints on how long the U.S. can continue this war and on how Trump is going to see any kind of upside from it.
Robinson Meyer:
[20:46] Nor has Trump tried to convince his coalition that a war with Iran is a national priority. But let’s talk about energy. I think the first place that people’s minds go when you’re talking about Iran, when you’re talking about the Strait of Hormuz, is oil. Why is the Strait of Hormuz particularly important to the global oil market? And then second of all, like what have we seen as the initial effects here?
Gregory Brew:
[21:09] So the Strait of Hormuz matters for three reasons. One, it is a very narrow waterway. So it is quite easy, theoretically, to block it.
Gregory Brew:
[21:19] Other waterways, even the Bab el-Mandab and the Red Sea, the Strait of Malacca, other strategic pathways through which large quantities of energy move are not so easily disrupted as the Strait of Hormuz. That’s reason number one. Reason number two, Iran. Iran is there. Iran frequently threatens to block the Strait of Hormuz, frequently threatens to close the Strait of Hormuz. It is a hostile actor vis-à-vis the other states in the region. We are now seeing proof of that, given that it is open fire on the GCC in a concerted way. That’s another reason why the Strait of Hormuz gets so much attention as far as the connection between the strait, the strait security and the situation in the global oil market. The third reason, I guess there are four reasons. The third reason is the volume of energy moving through the strait. It’s close to a fifth of global oil supply. It’s 20 million barrels a day, sometimes a little more. It’s a significant portion of the global LNG supply coming from Qatar has to pass through the Strait of Hormuz. A large quantity of refined products, metal distillates, condensates, fuel oil moves through the strait. So the volume affected by the strait being closed or disrupted or affected in some way is very, very large. Finally, fourth point, there’s nowhere else to go. You can’t go around the Strait of Hormuz. You have to go through it.
Gregory Brew:
[22:29] Tankers that can’t transit the strait or are blocked from doing so have no other options. There’s no Africa route as there was with the Red Sea disruption. So for those four reasons, the Strait of Hormuz gets a lot of attention. And it’s why it’s getting attention now. Although, interestingly enough, price of oil has responded, but has not moved so in a significant way, at least per some people’s expectations.
Robinson Meyer:
[22:51] Well, the theme of the year in oil so far has been that there’s a glut of oil. Or there’s at least a small glut of oil. We’ve kind of been dealing with that for a long time. And so I wonder if that is in some ways, one hesitates to call this good for oil markets, but it is kind of solving an issue for the market. Do you think oil is the most important energy product affected by this war?
Gregory Brew:
[23:15] Well, it’s certainly the largest in terms of volume, given how much oil moves through the strait. However, I think this could end up being a gas story as much as an oil story for two reasons. One, gas has already been physically affected. Just this morning, Qatar LNG put out a notice saying that it was halting production due to Iranian attacks on its facilities. Theoretically, this means that all Qatari LNG exports will be halted. And Qatar is among the top three global LNG producers. So if that happens, global LNG supply will be significantly constrained.
Gregory Brew:
[23:45] So far, there hasn’t been any significant constraints to oil supply. Tankers have paused in transiting the Strait of Hormuz, but physical disruptions haven’t yet occurred. The second reason is the state of the global gas market is tighter than the state of the global oil market. Oil is in a slight imbalance in supply versus demand. That’s been what has been keeping prices relatively low over the last six months, geopolitics notwithstanding. By comparison, gas inventories in Europe and Northeast Asia are fairly low as these countries are coming out of the winter months. So the effect of a Qatar shutoff or the effect of a significant disruption in LNG traffic through the strait, even if it is only short, could end up having fairly significant effect. Finally, prices, gas prices have shot up today much higher relative than to the increase in oil prices. So already the gas market is responding in a more significant way than the oil market has.
Robinson Meyer:
[24:34] Who will feel the effect of tighter and higher LNG markets and prices? I mean, is this primarily a Japan and Europe story? Is this something where in the U.S., I mean, we explored a lot of LNG, but would we expect those LNG prices to translate back into domestic gas prices?
Gregory Brew:
[24:50] I think gas prices in the U.S. are likely to remain fairly low. They may increase slightly as the average LNG price globally increases. But I think this will affect Europe, particularly as their inventories are somewhat lower than major Northeast Asia importers like Japan and South Korea. The Europeans are still getting over the long effects of the war in Ukraine, moving away from dependence on Russian gas. They’ve had to depend on LNG to a more considerable degree. So a disruption on this scale, if it proves lasting, could be quite bad for the affordability of energy in Europe. Europe’s not going to run out of gas, but it will be forced to pay more money for it. Finally, there could be a dynamic that we saw in 2022, where all other markets that can’t compete with the high prices that Europe is demanding feel the effects. Markets like Southeast Asia or South Asia will see perhaps less access to LNG if more cargos are being diverted to Europe to take advantage of the very healthy
Gregory Brew:
[25:41] arbitrage opportunities between Europe gas prices and those in the United States.
Robinson Meyer:
[25:45] What do you think we learned from the 2022 post-Ukraine energy shock that might be applied now? Like what emerged then that could affect what we’re about to see?
Gregory Brew:
[25:56] I think if this conflict does end up disrupting LNG exports in a significant way, where the disruption lasts more than a few days, where the prices rise and remain high, I think it will offer up a similar lesson to the war in 2022, which is that LNG can be very volatile. It can be very reliable, but during periods of intense geopolitical conflict with supplies like Qatar being affected by conflict, affected by security in the region, that ends up hitting consumers because it ends up, they end up having to shoulder much higher prices. They end up having to shoulder the burden of insecure energy. One of the arguments made against LNG over the last couple of years is that while it is, while it makes a lot of sense, the economics make a lot of sense. If it’s continually exposed to these kinds of volatile spikes, if geopolitics keeps the average price of gas much higher than that of coal or renewables, then ultimately LNG can’t compete with those alternative sources of supply. Even if the economics make sense, the geopolitics might not.
Robinson Meyer:
[26:54] Well, and this is what I was thinking. From some climate folks, I think there’s been a turn after this conflict, as there is after many conflicts, to say, look, this is why renewables are so important, because they don’t experience this price volatility in the same way that LNG does. The issue is coal also doesn’t really experience this price volatility. And frankly, many, many countries around the world, particularly those that suffer when LNG prices go up in sub-Saharan Africa and Southeast Asia, do actually have ample coal resources. And if they need to, they’ll learn from the Chinese example, as much as building solar and batteries is important, so is building a big coal fleet because you always have security of supply with coal.
Gregory Brew:
[27:35] Absolutely.

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.
