Tonight, for the third time, Donald Trump will accept the Republican Party’s nomination for president. But this time, for the first time ever, Trump is also on track to outright win the presidential election he is involved in. He has opened a two-point lead in polling averages, but some polls show a more decisive margin in swing states; no Democrat has been in a worse position in the polls, at this point in the election, since the beginning of the century. Even Trump’s decisions — his selection of JD Vance as his vice president, for instance — suggests that Trump is planning to win.
And so it is time to begin thinking in earnest about what a Trump presidency might mean for decarbonization and the energy transition. For the next several months, Heatmap’s journalists will cover — with rigor, fairness, and perspicacity — that question. (They already have.)
Should Trump win, there are a few predictions we can make with relative certainty. The Trump administration will roll back the Environmental Protection Agency’s car and truck pollution rules, which Republicans describe as a tyrannical EV mandate forced on unwilling American consumers. Trump will also try to unwind the EPA’s restrictions on carbon emissions from power plants. And he will once again take the United States out of the Paris Agreement, just as he did during his first term. Trump has also pledged to reclassify more than 50,000 federal employees as political appointees. That would make it possible for them to be fired en masse.
Make no mistake, Trump would be a disaster for American climate policy — and if your biggest issue is that the United States should aim to rapidly reduce its emissions of heat-trapping pollution, then you probably shouldn’t vote for him. But just because he will wreck climate change policy doesn’t guarantee that he will destroy the clean energy economy. A second Trump administration would be a bleak time for decarbonization advocates, but it would not be a hopeless time — even if we see a powerful and even Caesarist Trump administration, politics would go on. It is worth thinking about what those politics could look like ahead of time.
Trump’s first term saw no shortage of contradictions in his climate program. Trump was a climate change denier who seemed to revel in unraveling environmental programs. But he also ultimately signed the Energy Act of 2020, a bipartisan package written by Senator Joe Manchin and Lisa Murkowski that boosted the advanced nuclear industry, energy storage, and carbon capture, and which created programs that were later funded by Biden’s Bipartisan Infrastructure Law.
Another key contradiction in Trump’s first term was the interplay of the executive and legislative branches. Trump’s political appointees — including Scott Pruitt, his notorious and scandal-ridden EPA chief — pursued an aggressively pro-carbon agenda, rolling back environmental protections and opening up huge new swaths of public land to oil and gas drilling. The White House kept proposing budgets that cut tens of billions of dollars from key federal programs, including the EPA and the Department of Energy.
But Congress never actually passed those budgets. It became one of the strangest two-steps of the Trump administration: Again and again, the White House would unveil a radical, lacerating budget proposal that zeroed out key programs across the federal government and sent it to Congress. The press would cover Trump’s plans to destroy federal agencies, and the public would react with alarm. Then, several months later, Congress would pass a far more conventional budget. In May 2017, for example — the peak of Trump’s post-election Republican trifecta — Congress passed a budget that preserved nearly all EPA programs and increased funding for some renewable energy programs, including ARPA-E.
This doesn’t mean that the EPA and other federal agencies survived the first Trump administration unscathed. Many federal agencies saw brain drain throughout the four years of Trump; when Biden took office in 2021, his political appointees said that their first act was to rebuild the agencies’ depleted capacity. And if Trump carried out his aspiration of firing tens of thousands of federal workers, then the agencies would be even more beset, even more dysfunctional, at the end of his next term.
But the Trump White House seemed torn between the impulse to radically restructure the administrative state and the need to finalize its own deregulatory rules. The administration’s incompetence at dotting its i’s and crossing its t’s kept getting in the way of its own agenda: While the federal government usually beats legal challenges to its own rules, the Trump administration lost roughly 80% of its court fights.
Now, unlike during his first term, Trump will have a more favorable Supreme Court to work with: Conservatives now hold a 6-3 majority on the high court — and it could easily become 7-2 under a Trump administration. Last month, the Supreme Court made it harder for the regulatory state to issue any new rules, essentially subjugating agency authority to the judiciary. That could allow the Supreme Court to force a Trump initiative into law — but it could also hamstring Trump’s agencies by forcing them to do more work, to file more paperwork, to respond to even more public comments.
A second Trump presidency will differ from its prequel in at least one respect: its fossil fuel of choice. Throughout the 2016 election, Trump bound his campaign to the coal industry, pledging to bring back mining jobs and end Obama’s “war on coal.” Soon after his election, he received a coal “action plan” directly from Bob Murray, the CEO of what was then the country’s largest coal company.
Trump failed. Murray’s company declared bankruptcy in 2019, and coal mining jobs collapsed to a historic low in November 2020. (Coal mining employment has modestly recovered under Biden.) Now, as Heatmap columnist Paul Waldman has observed, Trump barely talks about coal at all; he now seems to revere the oil and gas industry. In April, he met with oil and gas executives at Mar-a-Lago and asked for $1 billion in campaign donations.
This speaks to another contradiction that’s far bigger than Trump, between the varying needs of big and small fossil fuel companies. Climate advocates sometimes talk about “the fossil fuel industry” as a monolith, but in fact it is riven with its own divisions and disagreements. Oil and natural gas companies have different demands from coal companies. There are also disagreements between large oil companies, such as ExxonMobil, whose size lets them afford higher regulatory burdens, and smaller oil and gas drillers, who oppose any regulation whatsoever. This divergence could affect how the Trump administration handles the EPA’s methane rules, which require oil companies to cap and monitor greenhouse gas emissions from oil and gas drilling equipment.
Then there’s nuclear power, the country’s most prolific zero-carbon fuel, which enjoys nearly unmatched bipartisan support but which some voters are much more wary of. Many nuclear advocates see Trump as neutral on the technology, even a potential ally, but Project 2025 proposes canceling the tens of billions of dollars in nuclear subsidies that the Biden administration has proposed. That would render the industry uneconomic and force many plants to close.
These are, of course, not even the most important contradictions that will define Trump’s White House. (I remain curious, for instance, about how Trump’s backers in Silicon Valley — whose personal wealth is tied up with big American tech companies and who detest Biden’s aggressive approach to antitrust enforcement — feel about Trump’s devil-may-care approach to defending Taiwan or about J.D. Vance’s praise of Lina Khan.)
Trump has promised to bring back manufacturing to the United States and wage a trade war on China. He also opposes electric vehicles. But some of the country’s biggest new manufacturing facilities are going to make EVs and batteries — and these are in the Republican heartland of South Carolina, Tennessee, and Texas, as well as the battleground state of Georgia. Trump has pledged to repeal the Inflation Reduction Act’s $7,500 tax credit for buying EVs, and Project 2025 proposes neutering the Energy Department’s Loan Programs Office, which can lend money to fund new EV factories. How will those anti-decarbonization policies fit in with local Republican economies? It is not hard to imagine a world where Trump repeals the consumer tax credit for EVs and claims victory over it, but preserves the IRA’s far more lucrative 45x subsidy that rewards companies that make batteries and EVs. That would leave some of the most important pro-EV policy in the IRA intact while generating the necessary anti-climate headlines.
These focuses of ideological slippage shouldn’t make climate advocates feel more relaxed — on the contrary, some of Trump’s most authoritarian impulses have been unleashed in response to political weakness or outright unpopularity. Perhaps that’s most clear around Trump’s outright denial of climate change, which remains among the most unpopular parts of his agenda. Is it any wonder that Jeffrey Clark, a climate-questioning environment lawyer who Trump installed at the Justice Department, ultimately helped lead the department’s attempt to overturn the 2020 election?
The great irony — you might even say tragedy — of American energy policy is that voters across the parties see energy as a culture war issue. Environmentalists dream of creating an all-renewable energy system even though it would gobble up massive amounts of land. Republicans talk about supporting nuclear power, even though the nuclear industry has always and everywhere required state support. Trump, a pile of contradictions himself, and a distracted culture warrior, will only accelerate these contradictions. I am by no means optimistic about the results. But I expect that the reality of Trump’s governance will, even on these issues, surprise us.

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.
