And make a meaningful difference in the fight against climate change, while you’re at it.

Welcome to
Decarbonize Your Life, Heatmap’s special report that aims to help you make decisions in your own life that are better for the climate, better for you, and better for the world we all live in.
This is our attempt, in other words, to assist you in living something like a normal life while also making progress in the fight against climate change. That means making smarter and more informed decisions about how climate change affects your life — and about how your life affects climate change. The point is not what you shouldn’t do (although there is some of that). It’s about what you should do to exert the most leverage on the global economic system and, hopefully, nudge things toward decarbonization just a little bit faster.
We certainly think we’ve hit upon a better way to think about climate action, but you don’t have to take our word for it. Keep reading here for more on how (and why) we think about decarbonizing your life — or just skip ahead to our recommendations.
At this point, everyone knows that individual action won’t solve climate change. Didn’t BP invent the term “carbon footprint” in 2004 so as to distract from fossil fuel companies’ guilt and greed?
As the journalist Rachel Cohen has observed, around the 2010s it became unpopular to believe that individual action could help address any major social problem. And sure, it’s true that only collective action — achieved through something like the political system — will let us eventually manage climate change at the global level.
But at Heatmap, we believe that that isn’t quite the whole story. Just because politics and collective action are the only things that can solve climate change doesn’t mean they are the only things that can do something about climate change. What’s more, the problem of carbon emissions — and the stickiness of fossil fuels — emerges from a tight knot of chemical efficiency, political power, and logistical lock-in. If individual consumers can pry at that knot, can make it a little easier to imagine a post-fossil energy system, then they can realize a zero-carbon world a little sooner.
That way of thinking about climate change, however, requires us to think somewhat differently about how to take individual action in the first place. Often, when you read about how to fight climate change as a person or family, the advice assumes that you want to reduce your responsibility for climate change. You’re advised to turn down the thermostat in the winter (or turn it up in the summer), shut off the lights when you leave the room, and compost.
This advice assumes that the reader’s goal is to personally exculpate themselves or their family from global warming — and to assuage their own guilt for participating in a polluting system.
At its most sophisticated, this advice can be valuable insofar as it can help you cut your marginal carbon emissions. The most precise versions of these recommendations often speak in terms of emissions abatement: They might advise, say, that switching to a plant-based diet could save 0.8 tons of carbon emissions a year.
You’ll see some of that kind of recommendation in this project: It’s a valid way to think about individual actions, and it works especially well in some domains, such as food. But it’s not, in our view, the best way of thinking about individual action to fight climate change.
That’s because it is essentially impossible to exculpate yourself from climate change. That’s not being fatalistic. It’s just a fact. Simply by living in the year 2024, your life is enmeshed in a sprawling economic network that devours fossil fuels as its great lifestyle subsidy. Look out the nearest window — do you see cars, asphalt, power lines, sidewalks, buildings? Do you see steel-framed structures or a plane cutting its way across the sky? None of those things could exist without fossil fuels. And unless you’re looking into wild and unkempt wilderness (if so, lucky you!), then even the plants and grass out your window, the food in your pantry, grew up on fertilizer that was manufactured with fossil fuels. If you live in a rich or middle-income country, buy goods and clothes, eat food, use electricity, or even leave your house by any means other than walking, then you are responsible, to some degree, for climate change.
Trying to zero out your personal carbon footprint, in other words, is a fool’s errand. What you can do, however, is maximize the degree to which you’re building a new, post-fossil-fuel world.
To be clear, we don’t mean that in a woo-woo way. We’re not saying you should imagine a kumbaya world where we all hold hands and take public transit to the nearest all-volunteer renewable-powered co-op. We’re saying that there are real, already existing products and technologies that must become a bigger part of today’s built environment if we are to have any hope of solving climate change. What you can do — and what we recommend in this guide — is help take those technologies from the fringes into the center of everyday life. If you want to decarbonize the whole planet, you should think about decarbonizing your life.
What we have tried to do here is not focus on how to reduce your marginal emissions — the number of tons that you, personally, are responsible for pumping into the environment. Instead, we’re trying to help you understand how to focus on high-leverage actions — the kinds of choices that can drive change throughout the energy system. That’s why in this guide you’ll find advice on how to switch to an EV, buy zero-carbon electricity, make your home more energy-efficient, and electrify your appliances. We also recommend these in the order that we think they’ll be most effective — to learn more about how we reached that ranking, read about our methodology here.
The kind of shifts we advise in this guide, to be clear, won’t solve climate change on their own. But they will help you alter the systems in which you’re enmeshed, and they’ll make you a smarter climate citizen.
Flying is maybe the trickiest climate question. Although it makes up a relatively small share of both global and U.S. emissions — about 2% each — it is among the most climate-polluting activities many Americans will do on a minute-to-minute basis. (Although if you live in a dense and walkable city like New York, San Francisco, or Washington, D.C., but travel frequently, then flying may make up a large share of your emissions.) It is probably also the most difficult “everyday” activity to decarbonize.
There is no practical substitute for long-distance or transcontinental flying. Today, only one ocean liner regularly makes the journey from New York to London, and it departs from each city only once a month. And unless you hitch a ride on a container ship, there is literally no slow boat to China. If you want to travel abroad, then you must fly. Even within the United States, there is essentially no substitute for long-distance flights. Europeans and East Asians can rely on superior long-distance rail systems, but America’s extensive road network, unusually high infrastructure costs, sclerotic rail agency, and chronic lack of transit investment mean that Americans are stuck with flying or driving.
Commercial aviation is a miracle of the modern world: It facilitates a level of global connectedness and international communication that earlier generations could only dream of. Affordable and long-distance passenger flight is, in many ways, the crowning achievement of our highly technical society, and it allows for the amount of global immigration and mass tourism that defines the modern world. (If you have a private jet, of course, stop using it. Because so few people take each flight, private jets are uniquely destructive for the climate, emitting every seven hours what the average American emits all year.)
Fossil fuels’ weight and energy density is ideal for flying. There is, right now, no drop-in replacement for jet fuel that is being produced at scale. So while we have some advice about how to mitigate your climate pollution from flying, it won’t make up a large part of this guide. Reduce the number of flights you take if you can, sure, and take more direct flights if possible. But the truth is that for now, there are smarter and more high-leverage decisions that you can make.
Only decarbonization can get us closer to tackling climate change once and for all. Our belief at Heatmap is that if you care about climate change, then decarbonization — and not mere emissions reductions — should be your guiding star. If you want to follow that star, then read on.

“It is difficult to imagine more arbitrary and capricious decisionmaking than that at issue here.”
A federal court shot down President Trump’s attempt to kill New York City’s congestion pricing program on Tuesday, allowing the city’s $9 toll on cars entering downtown Manhattan during peak hours to remain in effect.
Judge Lewis Liman of the U.S. District Court for the Southern District of New York ruled that the Trump administration’s termination of the program was illegal, writing, “It is difficult to imagine more arbitrary and capricious decisionmaking than that at issue here.”
So concludes a fight that began almost exactly one year ago, just after Trump returned to the White House. On February 19, 2025, the newly minted Transportation Secretary Sean Duffy sent a letter to Kathy Hochul, the governor of New York, rescinding the federal government’s approval of the congestion pricing fee. President Trump had expressed concerns about the program, Duffy said, leading his department to review its agreement with the state and determine that the program did not adhere to the federal statute under which it was approved.
Duffy argued that the city was not allowed to cordon off part of the city and not provide any toll-free options for drivers to enter it. He also asserted that the program had to be designed solely to relieve congestion — and that New York’s explicit secondary goal of raising money to improve public transit was a violation.
Trump, meanwhile, likened himself to a monarch who had risen to power just in time to rescue New Yorkers from tyranny. That same day, the White House posted an image to social media of Trump standing in front of the New York City skyline donning a gold crown, with the caption, "CONGESTION PRICING IS DEAD. Manhattan, and all of New York, is SAVED. LONG LIVE THE KING!"
New York had only just launched the tolling program a month earlier after nearly 20 years of deliberation — or, as reporter and Hell Gate cofounder Christopher Robbins put it in his account of those years for Heatmap, “procrastination.” The program was supposed to go into effect months earlier before, at the last minute, Hochul tried to delay the program indefinitely, claiming it was too much of a burden on New Yorkers’ wallets. She ultimately allowed congestion pricing to proceed with the fee reduced from $15 during peak hours to $9, and thereafter became one of its champions. The state immediately challenged Duffy’s termination order in court and defied the agency’s instruction to shut down the program, keeping the toll in place for the entirety of the court case.
In May, Judge Liman issued a preliminary injunction prohibiting the DOT from terminating the agreement, noting that New York was likely to succeed in demonstrating that Duffy had exceeded his authority in rescinding it.
After the first full year the program was operating, the state reported 27 million fewer vehicles entering lower Manhattan and a 7% boost to transit ridership. Bus speeds were also up, traffic noise complaints were down, and the program raised $550 million in net revenue.
The final court order issued Tuesday rejected Duffy’s initial arguments for terminating the program, as well as additional justifications he supplied later in the case.
“We disagree with the court’s ruling,” a spokesperson for the Transportation Department told me, adding that congestion pricing imposes a “massive tax on every New Yorker” and has “made federally funded roads inaccessible to commuters without providing a toll-free alternative.” The Department is “reviewing all legal options — including an appeal — with the Justice Department,” they said.
Current conditions: A cluster of thunderstorms is moving northeast across the middle of the United States, from San Antonio to Cincinnati • Thailand’s disaster agency has put 62 provinces, including Bangkok, on alert for severe summer storms through the end of the week • The American Samoan capital of Pago Pago is in the midst of days of intense thunderstorms.
We are only four days into the bombing campaign the United States and Israel began Saturday in a bid to topple the Islamic Republic’s regime. Oil prices closed Monday nearly 9% higher than where trading started last Friday. Natural gas prices, meanwhile, spiked by 5% in the U.S. and 45% in Europe after Qatar announced a halt to shipments of liquified natural gas through the Strait of Hormuz, which tapers at its narrowest point to just 20 miles between the shores of Iran and the United Arab Emirates. It’s a sign that the war “isn’t just an oil story,” Heatmap’s Matthew Zeitlin wrote yesterday. Like any good tale, it has some irony: “The one U.S. natural gas export project scheduled to start up soon is, of all things, a QatarEnergy-ExxonMobil joint venture.” Heatmap’s Robinson Meyer further explored the LNG angle with Eurasia Group analyst Gregory Brew on the latest episode of Shift Key.
At least for now, the bombing of Iranian nuclear enrichment sites hasn’t led to any detectable increase in radiation levels in countries bordering Iran, the International Atomic Energy Agency said Monday. That includes the Bushehr nuclear power plant, the Tehran research reactor, and other facilities. “So far, no elevation of radiation levels above the usual background levels has been detected in countries bordering Iran,” Director General Rafael Grossi said in a statement.
Financial giants are once again buying a utility in a bet on electricity growth. A consortium led by BlackRock subsidiary Global Infrastructure Partners and Swedish private equity heavyweight EQT announced a deal Monday to buy utility giant AES Corp. The acquisition was valued at more than $33 billion and is expected to close by early next year at the latest. “AES is a leader in competitive generation,” Bayo Ogunlesi, the chief executive officer of BlackRock’s Global Infrastructure Partners, said in a statement. “At a time in which there is a need for significant investments in new capacity in electricity generation, transmission, and distribution, especially in the United States of America, we look forward to utilizing GIP’s experience in energy infrastructure investing, as well as our operational capabilities to help accelerate AES’ commitment to serve the market needs for affordable, safe and reliable power.” The move comes almost exactly a year after the infrastructure divisions at Blackstone, the world’s largest alternative asset manager, bought the Albuquerque-based utility TXNM Energy in an $11.5 billion gamble on surging power demand.
China’s output of solar power surpassed that of wind for the first time last year as cheap panels flooded the market at home and abroad. The country produced nearly 1.2 million gigawatt-hours of electricity from solar power in 2025, up 40% from a year earlier, according to a Bloomberg analysis of National Bureau of Statistics data published Saturday. Wind generation increased just 13% to more than 1.1 gigawatt-hours. The solar boom comes as Beijing bolsters spending on green industry across the board. China went from spending virtually nothing on fusion energy development to investing more in one year than the entire rest of the world combined, as I have previously reported. To some, China is — despite its continued heavy use of coal — a climate hero, as Heatmap’s Katie Brigham has written.

Canada and India have a longstanding special friendship on nuclear power. Both countries — two of the juggernauts of the 56-country Commonwealth of Nations — operate fleets that rely heavily on pressurized heavy water reactors, a very different design than the light water reactors that make up the vast majority of the fleets in Europe and the United States. Ottawa helped New Delhi build its first nuclear plants. Now the two countries have renewed their atomic ties in what the BBC called a “landmark” deal Monday. As part of the pact, India signed a nine-year agreement with Canada’s largest uranium miner, Cameco, to supply fuel to New Delhi’s growing fleet of seven nuclear plants. The $1.9 billion deal opens a new market for Canada’s expanding production of uranium ore and gives India, which has long worried about its lack of domestic deposits, a stable supply of fuel.
India, meanwhile, is charging ahead with two new reactors at the Kaiga atomic power station in the southwestern state of Karnataka. The units are set to be IPHWR-700, natively designed pressurized heavy water reactors. Last week, the Nuclear Power Corporation of India poured the first concrete on the new pair of reactors, NucNet reported Monday.
The Spanish refiner Moeve has decided to move forward with an investment into building what Hydrogen Insight called “a scaled-back version” of the first phase of its giant 2-gigawatt Andalusian Green Hydrogen Valley project. Even in a less ambitious form, Reuters pegged the total value of the project at $1.2 billion. Meanwhile in the U.S., as I wrote yesterday, is losing major projects right as big production facilities planned before Trump returned to office come online.
Speaking of building, the LEGO Group is investing another $2.8 million into carbon dioxide removal. The Danish toymaker had already pumped money into carbon-removal projects overseen by Climate Impact Partners and ClimeFi. At this point, LEGO has committed $8.5 million to sucking planet-heating carbon out of the atmosphere, where it circulates for centuries. “As the program expands, it is helping to strengthen our understanding of different approaches and inform future decision-making on how carbon removal may complement our wider climate goals,” Annette Stube, LEGO’s chief sustainability officer, told Carbon Herald.
In this special edition of Shift Key, Rob talks to Eurasia Group’s Gregory Brew about how the U.S.-Israeli-led conflict will reshape global energy markets.
The United States and Israel have launched a devastating new war on Iran. What has happened so far, when could it end, and what could it mean for oil, gas, and the global energy shift?
Rob is joined by Gregory Brew, an analyst with the Eurasia Group’s energy, climate, and resources team focused on the geopolitics of oil and gas. He serves as the group’s country analyst for Iran. He’s also an historian of modern Iran, oil, and U.S. foreign policy, and the author of two books about the subject.
Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap News.

Here is an excerpt from their conversation:
Robinson Meyer: 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, what have we seen as the initial effects here?
Gregory Brew: 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. 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. 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.
Meyer: 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 way — 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?
Brew: 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.
