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.

Many nonprofits representing the environmental and climate movement are split.
This is Heatmap Daily, an evening digest written by our executive editor.
It’s now been just over a week since a gang of four bipartisan senators released the Bipartisan American Affordability and Jobs Act, or BAAJA. The permitting reform proposal would make too many changes to federal law to summarize cleanly here — read our explainer for that — but suffice it to say it creates a messy group of winners and losers. Utilities, data centers, and the Trump administration would lose; electricity ratepayers, clean energy companies, long-distance transmission lines, and natural gas pipeline builders win. (As would geothermal startups, virtual power plant providers, and a few other climate tech subsectors that my colleague Katie Brigham recently detailed.)
In the ensuing week since its release, we’ve gotten a better sense of the battle lines over the bill. The hardhat unions largely support the proposal (although the International Brotherhood of Electrical Workers, which is often aligned with utility executives, has stayed notably silent on it.) Clean energy trade groups, such as the American Clean Power Association, back it, too, as do fossil fuel lobbying groups, such as the American Petroleum Institute.
Groups representing the environmental and climate movement are more split, and some of the most influential nonprofits have yet to render a verdict. Earlier today, the Sierra Club published its first take on the proposal, which it described as a “hard look” at the bill. The Natural Resources Defense Council asked its own “hard questions” last Friday. Neither document rejects the proposal outright, although both are critical, and both suggest that future statements are coming.
To some degree, the statements say what you might expect: The groups like all the parts of the compromise that Democrats fought for (such as those that will encourage transmission) and dislike what Republicans wanted (such as those that will ease some pipeline permitting). That is what a compromise means — and for congressional procedure reasons too tedious to explain here, permitting reform will likely always need to be passed as a bipartisan compromise, because it will always need to overcome a 60-vote Senate filibuster.
The Sierra Club’s assessment divides the bill into “green flags,” which will make “long-overdue changes to protect consumers and level the playing field for proposed transmission,” such as by making it easier to plan long-distance power lines, protect ratepayers from utility and data center freeloading, and clarify who in the government can approve power lines. It also names four “red flags,” including the “hollowing out” of court authority over some permits, the removal of a Clean Water Act provision that lets governors block pipelines and power lines, and the option to delegate partial Endangered Species Act enforcement to state governments.
This is a helpful scheme, and I hope the Sierra Club continues using it. But I think it would be a mistake to analyze the bill solely through this metric, because it implicitly assumes we are starting from a neutral baseline — or that every additional “unit” of policy support, so to speak, helps an insurgent industry as much as it might aid an incumbent industry. To be clear: Although I’ve endorsed the idea of permitting reform in the past, I’ve been careful not to endorse or reject this particular permitting bill yet; I hope to write a more comprehensive take on this legislation — and whether I think it’s a good idea — before senators ultimately vote on it.
So for now, let me say that I think everyone should keep in mind that the baseline around U.S. energy permitting is, in fact, not neutral today. By this, I do not merely mean that natural gas pipelines already have a one-stop shop for federal permits, but transmission developers have to go hat in hand to every state government; nor that fracking is already carved out from some federal environmental review laws, but enhanced geothermal technology isn’t.
The mismatch goes deeper than that. Many of the discussions of the bill that I’ve seen seem to fear that the United States might witness some enormous and unprecedented fossil fuel buildout were the bill to pass. But make no mistake: We are already witnessing such a buildout. The United States is slated to add more than 60 gigawatts of new natural gas generation capacity by 2030 under its existing laws.
The existing system of laws, regulations, and procedures is failing to avert an enormous fossil fuel buildout. The existing system has proven itself completely inadequate to manage an era of electricity demand growth and the data center boom without surging fossil demand and sky-rocketing electricity prices. The existing system of laws is pushing hyperscalers and developers to burn natural gas on site, often through rudimentary jet engines.
And the existing system of laws has shown that fossil fuel consumers will go to great lengths to move and obtain fossil fuels, even when dedicated transport options like pipelines are not available. I’ve heard fears that the permitting bill will make it easier to build natural gas pipelines. But pipelines, to a dedicated artificial intelligence customer, are no constraint: Oracle is now delivering natural gas to some of its data centers by truck when pipeline capacity isn’t available.
There may be reasons for green groups to reject this deal. (And there may be reasons for Democratic lawmakers to support it anyway, even if environmental groups oppose it.) But the perfection of our current environmental and energy legal regime is not one of them. Even if your sole goal were to reduce the carbon emissions produced by the American energy system — even if you set aside the problems with cost, conventional pollution, or monopoly control — the current system sucks.
Advanced nuclear will take a decade or more to hit commercial scale. Meanwhile, the hyperscalers need power now. Enter the uprate.
When America’s tech titans started plowing money into nuclear technology to power data centers in 2024, companies such as Google and Amazon opted to invest first in next-generation reactor startups. But electricity demand is soaring today, and those projects are still years away — at least — from generating power at reasonable commercial rates.
So the industry is hedging by betting on existing nuclear plants to pump out more electricity in the near term. Uprates — renovations that allow nuclear operators to produce more power from existing reactors — are all the rage this year.
In February, the Department of Energy issued its largest-ever loan to Southern Company to fund up to 6 gigawatts of uprates across the utility’s nuclear fleet. Last week, Amazon signed a deal with Constellation Energy, the nation’s largest operator of nuclear reactors, to uprate the Calvert Cliffs plant in Maryland to generate another 190 megawatts on top of its current 1.8-gigawatt output. Soon after, the Energy Department offered nuclear operator Vistra a $4 billion loan to uprate plants in Ohio and Pennsylvania.
Then on Tuesday, Google inked its own deal with Constellation aimed at wringing out 890 megawatts of new power from 11 reactors across PJM Interconnection, the nation’s second-biggest and arguably most overworked grid system.
“Everyone loves nuclear, but it takes a really long time to build,” Raiford Smith, Google’s head of power and energy for the cloud, told me yesterday. “The fastest way to get it is via uprates. It’s real megawatts, but the quicker, shorter-term approach.”
Building new reactors, he said, “is the intermediate term plan, and we see fusion as the longer term bet.” Given that “new data centers are coming on at a gigawatt a clip, that means even with all the uprates, there’s still more to come,” he added.
The investments into existing nuclear stations deliver a win for Constellation, whose chief executive, Joe Dominguez, has been among the more vocal C-suite skeptics of what my colleague Matthew Zeitlin described as utility executives’ “load growth mania” over the past two years. But the deals say as much about the shifting lines in the debate over how to expand the nuclear power fleet in this country — what size reactors are better, how to finance projects — as the disagreement over how much new generation is needed to supply the artificial intelligence boom.
The deal “is a win-win,” Emmet Penney, the director of energy and infrastructure at the think tank Foundation for American Innovation, told me. “Constellation and Google are revealing just how essential our nuclear fleet is to maintaining our energy dominance.”
America’s last attempt at a nuclear buildout ended in a series of financial boondoggles. The problems traced back to numerous factors: Decades without any nuclear construction atrophied the workforce. Electricity market reforms aimed at breaking up monopoly utilities left the industry with few players equipped with large enough balance sheets to take on megaprojects that would take years to build and billions of dollars of upfront capital. Increased competition from cheap natural gas.
The only two new reactors that made it over the finish line, Southern’s pair of Westinghouse AP1000s at the Alvin W. Vogtle Generating Station in eastern Georgia, came in billions of dollars over budget, in part because the developers erred in choosing a Nuclear Regulatory Commission licensing pathway that required long stops and costly delays every time the builders tweaked the design. Since those were the first AP1000s constructed in the U.S., there were plenty of last-minute design kinks to iron out.
In the meantime, the industry rallied behind the idea of small modular reactors. By making individual reactors roughly a third or less powerful than large-scale units such as the AP1000, the thinking went, developers would need to buy more, helping the technology slide down the cost curve through repeated construction and assembly-line manufacturing of components.
While Google and Amazon both backed fourth-generation startups whose designs use coolants other than water, such as liquid sodium or helium gas, the only such reactor operating in the world is in China, and America’s track record of running similar plants is poor. As such, government-owned utilities such as Canada’s Ontario Power Generation and America’s Tennessee Valley Authority have thrown their weight behind third-generation SMRs that essentially just shrink down existing water-cooled technology. The first of GE Vernova Hitachi Nuclear Energy’s BWRX-300s, a 300-megawatt design based on the boiling water reactors that make up about a third of the U.S. fleet, is now underway at OPG’s Darlington plant. In the U.S., meanwhile, the NRC just issued a construction license for the TVA’s first BRWX-300.
But the completion of the second AP1000 at Plant Vogtle demonstrated an uncomfortable reality proposed by researchers at the Massachusetts Institute of Technology: That the next, cheapest reactor to build in the U.S. would be another of Westinghouse’s flagship design. Vogtle Unit 4 came online in 2024 roughly 30% cheaper and faster than its slightly older twin, Vogtle Unit 3.
If that reduction seemed to justify the approach SMR companies were pursuing, a report by an economist and former antinuclear researcher raises new questions. The study by Charles Komanoff, which I covered here last month, suggests that the number of reactors required to achieve major cost reduction through “economies of duplication” pales in comparison to the price drop achieved through “economies of scale.” In other words, the nuclear industry’s time-tested approach to making reactors more economical — making them bigger — is still the best bet.
The Trump administration certainly agrees. The Energy Department laid plans for at least 10 new AP1000s last year, and put up another nearly $20 billion loan package for utilities that form joint ventures with Westinghouse to build one of the 1,100-megawatt reactors. South Korea is currently working out the fine print on a deal to help finance and build as many as six AP1000s and two APR1400s, the Korean rival to the Westinghouse reactor.
Whether any American utilities step up to help build any of those AP1000s remains an open question.
“There’s no way any utilities could consider building a large AP1000 because doing so could bankrupt the whole operation, and they don’t have enough confidence,” Chris Gadomski, the lead nuclear analyst at the consultancy BloombergNEF, told me.
The workforce that constructed the two AP1000s at Vogtle, he said, are now out building data centers. Unlike the Chinese, whose state-owned nuclear companies reverse engineered the AP1000 and made it relatively cheap to build by constructing as many as half a dozen at a time at one location, “we don’t have the wherewithal or sites in this country to build six reactors at once,” Gadomski said. “You’re lucky to build two at one site in this country.”
So fusion and next-generation fission remain years away. Current-generation SMRs come with big questions. And the leading large-scale design, the AP1000, is proving a hard sell to utilities. That leaves two options: Restarting decommissioned plants and uprating current reactors. The Energy Department has pumped billions in loans into projects to restart at least three permanently closed reactors: Holtec’s Palisades plant in Michigan, NextEra’s Duane Arnold facility in Iowa, and Constellation’s Crane Clean Energy Center, née Three Mile Island, in Pennsylvania. The consensus among industry experts is that those are the only three that remain intact enough to start back up; every other shuttered plant is at too advanced a stage of demolition.
That leaves uprates.
There are limits to how much power can be drawn from existing plants, said Jeff Jenkins, the founder and managing partner of Bernhard Capital Partners, an investment firm whose portfolio includes Allied Power, a contractor that has worked with Constellation on past uprates. “There’s still a few gigawatts out there,” he said. “And a gigawatt is a lot.”
But ultimately, the U.S. nuclear buildout needs options.
“It’s very much a hedge,” Gadomski said. “They’re spreading their bets. That’s a strength of Google’s strategy. They’re willing to place bets on advanced reactors, fusion, and still try to double down on the capacity of existing plants.”
On methane rules, British wind, and the Israeli electricity market
Current conditions: Singapore’s air is the worst in the world as wildfire smoke from Indonesia chokes the city state and neighboring Malaysia • Following a summer-like heat wave, temperatures in the American West are set to drop by as much as 50 degrees Fahrenheit as a cold snap moves in • In the Gulf of Mexico, Tropical Storm Isaias officially strengthened into the first Atlantic hurricane of the season this morning.
With its offshore oil fields booming in Guyana and its opportunities opening in Venezuela, Exxon Mobil is eyeing the next location for the Americas’ oil and gas: Trinidad and Tobago. In an interview with the Financial Times this week, the company’s exploration chief said the island nation’s existing oil and gas industry could expand to tap the same basin east of Venezuela that has transformed Guyana from one of the hemisphere’s poorest nations to one of its richest in terms of per capita gross domestic product. “A lot of people ask, ‘well, where’s the next Guyana?’” John Ardill, Exxon Mobil’s vice-president and head of global exploration, told the newspaper. “In Trinidad, we moved in as a play extension to Guyana.” The agreement between Exxon Mobil and the Trinidadian government took “about half as long as it usually takes on a good day,” delivering a pact in “record time.”
America’s oil majors are also looking outside the hemisphere. As you may recall from August, I told you that Exxon Mobil was also considering a big investment in Africa, with Mozambique drawing particular attention. Brazil’s state-owned Petrobras, meanwhile, is expanding its own grasp on the Americas’ oil boom. On Wednesday, Upstream reported, the company bid $590 million for control of an ultra-deepwater concession.
The European Union is pausing implementation of its new rules requiring oil and gas exporters to more scrupulously track data on methane emissions. The U.S., on the other hand, is planning a straight-up rollback. At an oil industry conference in Santa Fe on Wednesday, Environmental Protection Agency Administrator Lee Zeldin teased out plans to gut core parts of the methane regulations finalized in 2024. “This proposal takes on many of the problems American producers and operators have raised with us,” Zeldin said, according to Argus Media. “That includes the burden on marginal wells and oil and gas operators in general, the super emitter program, associated gas and control device requirements.”
Record wind power generation may have slashed how much natural gas Britain needed to burn last month for electricity, but it “wasn’t enough to shield the country from surging prices triggered by the war in Iran,” Bloomberg reported. Wind turbines pumped out 6.6 terawatt-hours of electricity in September, a record for the month and 4% more than a year earlier. As a result, gas-fired generation plunged to its lowest level on record for that month. But day-ahead power rates still doubled from a year earlier.
The world’s capacity of floating offshore wind, the subset of the sector that could vastly expand the areas of shoreline dotted with turbines, has reached 382 megawatts, a 38% surge over the past 12 months, according to a Renewables Now writeup of the latest report from the trade group RenewableUK. Meanwhile, Poland has now constructed all 76 of the standard turbines built into the seabed of the Baltic Sea for its first offshore wind farm. One-third of the turbines are now generating power, according to offshoreWIND.biz.

South Korea plans to speed up its shift away from fossil fuels with a new goal of 100 gigawatts of low-carbon energy additions by 2030 and roughly $747 billion in government-led investment over the next decade. The plan, part of the Korean Green Transformation program, “seeks to make Korea one of the world’s top three green manufacturing powers by developing industries such as hydrogen-reduction steelmaking, next-generation solar cells, and all-solid-state batteries,” according to The Korea Times, an English-language daily. New nuclear reactors are also part of the strategy.
The move comes as Seoul advances construction of as many as eight nuclear reactors in the U.S., including six of America’s Westinghouse AP1000 and two of its own APR1400s, as I told you last week.
The utility megamerger of the century so far is “not in the best interest of Virginians.” That’s the judgment the state’s lieutenant governor, Ghazala Hasmi, rendered this week following a five-city public listening tour. The statement came ahead of the State Corporation Commission’s first local hearing on the deal, and marks what Utility Dive called “the most formal expression of opposition from Virginia’s executive branch so far.” Governor Abigail Spanberger, a fellow Democrat, has not yet taken a definitive position on the merger.
But the deal follows some clear market logic. Among the benefits: It would create, as my colleague Matthew Zeitlin wrote in May, “a storage juggernaut.”

Israel’s booming tech sector and soaring stock market are just two ways its economy has dramatically changed from the socialism that defined the early decades after the country’s founding in 1948. Now that shift also includes the electricity market. Since market reforms allowed private actors into the grid at the start of last year, more than 2 million citizens, representing more than 500,244 private and business customers, have switched from the Israel Electric Corporation to private providers, according to The Jerusalem Post. Ratepayers buying electricity from private suppliers enjoy discounted rates ranging from 7% to 20%, “thanks to the lower generation costs in the private market.” Another 23,286 households and businesses submitted requests to switch suppliers just last month. OPC Energy, an independent power provider based in Tel Aviv, raised $200 million in bond issuances in August.
