Hell is shopping for eco poop bags.
As much as I’m aware that blaming the climate crisis on individual consumer choices is a favorite smokescreen of large corporations and fossil fuel companies, it still totally kills me to buy single-use plastic bags. So when my household recently ran out of the 900 black disposable litter bags we’d bought on Wirecutter’s recommendation eons ago, I decided to be a Good Person and replace them with the most environmentally friendly option I could find. I mean, how hard could it be?
Hoo boy.
What started out as a naïve quest to find the greenest pet waste receptacle has become my Joker origin story. It’s turned me into Mark Ruffalo in Dark Water, except instead of taking on Dupont, I’m hounding companies with names like The Original Poop Bag and Doggy Do Good for the chemical makeup of their “green” bags. I’ve been red-pilled on advanced recycling. And, worst of all, I still haven’t actually bought a replacement — because the entire “green,” “biodegradable,” “plant-based,” “compostable” pet waste bag industry is built on misdirections, half-truths, and outright lies.
This might seem like a ridiculous thing to have spent my time obsessing over (and I don’t entirely disagree with you). But the greenwashing and obfuscation around these bags is part of a bigger story. Plastics are the fossil fuel industry’s last stand. The renewable energy transition, albeit in fits and starts, is here. Seeing the writing on the wall, companies like ExxonMobil, Shell, and Saudi Aramco are heavily investing in petrochemicals, which are used to make plastic and are expected to make up half of oil demand growth between now and 2050, according to the International Energy Agency (IEA). As Armco president and CEO Amin Nasser has reassured his cohorts, oil demand from petrochemicals is expected to remain high “no matter which energy transition scenario plays out.”
But I’m getting ahead of myself.
This story starts with much cuter villains: my cats.
Meet the adorable antiheroes of this story, Marinka and Virginia:
This whole piece is just an excuse to show you a picture of my cats.Jeva Lange/Heatmap
These two cutie pies don’t know it, but they diligently contribute to the 5.1 million tons of feces produced by America’s dogs and cats every year. One estimate of the dog sector alone found that disposing of all that waste adds some 500 million single-use bags to U.S. landfills annually.
The evils of single-use plastic bags have already been drilled into most of our heads by now: They take years to break down and when they do, they don’t decompose but rather turn into tiny microplastics that end up in the soil, waterways, food chain, and even our bloodstreams and breast milk. There is one seemingly great and trendy way to get around this: compostable bags!
Alas, if something sounds too good to be true, it is. For one thing, the “compostable” claims made by eco-friendly pet companies are wildly misleading. Though brands like to imply that their bags decompose and disappear like any other yard waste, these products only break down within a year under the extremely specific conditions of a commercial composting facility — very, very few of which even accept pet waste in the first place. As a result, the FTC has flagged that “compostable claims for these products are generally untrue.”
A "compostable" poop bag available on Chewy.com...Chewy.com
...and why you should always read the fine print.Chewy.com
Companies love to exploit consumers’ lack of knowledge around these terms and processes, though, and are mostly free to do so since the language isn’t strongly regulated. Often brands will brag that their compostable bags meet the “ASTM D6400 standard,” which just means they meet the industrial composting standard — again, pretty useless for us in this context. (Touting the ASTM D6400 standard is also often a way for brands to hide that their bags are made with virgin fossil fuels … more on that soon).
The bigger question when it comes to composting pet waste is, do we even want to? Dogs and cats are meat eaters, which means their poop contains parasites and bacteria like roundworms and hookworms, which can last for years in the soil and even be passed onto humans if used as a fertilizer for edible plants. While maybe this doesn’t sound like it could be that big of a problem, it is: “A study by the Bureau of Sanitation found that 60% of the bacteria in a Marina Del Rey, [California,] waterway was because of animals, domesticated and feral,” the Los Angeles Times reports. Gross.
This is one time you’ll ever hear me say that dog people have it better, though. Done correctly, dog owners actually can home compost dog waste if they’re so inclined. That said, a major downside of compostable bags is that they seem to lead some people to the impression that they can litter trails and parks with their “green” bags since the bags will eventually “go away.” As previously discussed: No, they won’t.
Cat waste, however, never basically should end up in your garden: Felines carry the parasite Toxoplasma gondii, which can be passed onto humans via compost but has been found to kill wildlife, including the sea otters in California. “Toxoplasma infections contribute to the deaths of 8 percent of otters that are found dead, and is the primary cause of death in 3 percent,” The New York Times explains. While feral cats used to be blamed for spreading the parasite, new evidence shows house cats almost certainly are, too — through their waste.
So compostable pet waste bags are out. As one municipality put it, dog and cat poop should be treated like what it is: not a fertilizer, but a pollutant. That means it needs to be sequestered, one way or another, in a landfill.
Just going to nip this one in the bud. For the same reason that composting pet waste isn’t advisable due to parasites and bacteria in four-legged meat-eaters’ feces, flushable pet waste bags and litter aren’t a safe or responsible choice, either.
Many waste treatment facilities don’t kill Toxoplasma, so putting cat poop in the toilet just expedites its journey into your local waterway. Indeed, in responding to an utterly unhinged email I sent them about cat waste, the California Association of Sanitation Agencies confirmed that “the only thing that should be flushed is human waste and toilet paper.”
Biodegradable pet waste bags are what radicalized me.
At first glance, these bags appear to be the best option. A number of them come on the recommendation of the sustainability website Treehugger. The product websites usually feature blogs full of reassuring information about how harmful plastic waste is, or boast 1% for the Planet certifications, or mention something about being made of cornstarch. Even the bags are green!
And almost all of them, despite their lofty claims, are made using virgin fossil fuels.
Polybutylene Adipate Terephthalate, or “PBAT,” is a biodegradable plastic made from the petrochemicals butanediol, purified terephthalic acid (PTA), and adipic acid. Translation: Fossil fuels must be extracted in order to make any bag that contains PBAT, which is virtually all of them.
Companies are exceptionally sneaky about this, though. Some of the brands boast outright about using PBAT as a traditional plastic alternative, likely assuming customers have no idea what the acronym means and won’t bother looking it up. Yet as Alice Judge, a former veterinarian and co-founder of the U.K.-based sustainable pet website Pet Impact, found in her own investigation, PBAT rarely makes up less than 60% of these supposedly “plant-based” pet waste bags. “There is some really concerning greenwashing and outright lying” going on in the industry, she told me. “We’ve found brands that are very big, reputable brands even saying explicitly ‘100% plant-based’ and in the same sentence saying ‘made from cornstarch and PBAT.’”
"Zero plastic" — but contains a fossil fuel-derived chemical called PBAT.Sirwaggingtons.com
PBAT is typically combined with cornstarch or sugarcane, so a “plant-based” bag advertising those ingredients can often be a tip-off that a fossil fuel product is also involved. Additionally, companies will frequently flag on their packaging that they meet the ASTM D6400 or BPI standards, though these have no provisions against certifying biodegradable products that contain PBAT.
Pet waste bag companies appear to go out of their way to avoid these admissions. Doggy Do Good, a popular sustainable pet waste company, told me in an email they use a “proprietary bio-based material” for “60.9% of the composition of their bags” — that is, the expected amount of PBAT — and added that “this fully biodegradable copolymer is an excellent alternative to polyethylene.” When I pressed to clarify if their proprietary “biodegradable copolymer” in question was PBAT, as I suspected, they stopped replying to my emails. The Original Poop Bag, another green bag company, didn’t answer me at all when I asked if their bags contained the fossil fuel product.
Despite these avoidance tactics, biodegradable bag companies aren’t using PBAT because they nefariously want to ruin the planet. It’s just the dirty secret of the pet waste bag business. As Judge explained in a blog post, “All poo bags have to include PBAT for strength and structure. If they were 100% plant-based, they would turn to mush very quickly when wet, lack strength, and tear easily (some qualities you really don’t want in a poo bag!).”
Fair enough. It’s the lack of transparency that is the problem: Most of these companies are selling fossil fuel-based products to customers who think they’re buying bags made from corn.
What's the other 62%?Doggydogood.com
Ultimately, there are two ways to think about the impact of the pet waste bags you buy: the impact of the materials used to make them and the impact of their disposal. If the latter is your biggest concern — what happens to bags after they’ve been used — biodegradable and “plant-based” bags are still probably the best, if imperfect, option available on the market. You can throw them in the trash (where they belong because again, pet poop is a pollutant) but also know at least that they’ll eventually biodegrade in a landfill (it should be noted, though, that everything is technically biodegradable, and the word means nothing without specification about the timeline and conditions).
From an “input” perspective — what the bags are made of, and how — biodegradable and “plant-based” bags are a little less exciting. They require less virgin fossil fuel than buying a bag entirely made out of traditional single-use plastic, though some research has suggested there is “no real difference in lifetime emissions between” products made with traditional plastic and those made from bioplastics. By another estimate, greenhouse gas emissions “are typically higher for bio-based plastics than recycled and virgin plastics” because “corn requires large amounts of energy, space, and water to grow industrially” and “turning the corn starch (once cultivated) into a polymer requires considerable energy.”
There is one major exception to all of this: Avoid “oxo-biodegradable” products. These are banned in the EU because they break down, sure — but into toxic microplastics.
Though they’re comparatively rare, you can find “recycled plastic” pet waste bags on the market. They apparently cut down on virgin fossil fuels by recycling plastic that’s already been extracted. (Judge’s company, Pet Impact, sells its own poo bag made from recycled ocean plastic, oyster shell waste, and “about 25 to 30%” virgin fossil fuels).
Even 100% recycled materials have their problems.
But while recycled plastic sounds great, it has — you guessed it — its own complications.
“Chemical” or “advanced” plastic recycling is the current sweetheart of the oil and gas industry, despite evidence that recycling plastic isn’t nearly as good as it’s chalked up to be. For one thing, the process of converting old plastics into new plastics is incredibly emissions-intensive and thus requires the burning of fossil fuels to generate the required energy. The recycling process can also spew cancer-causing chemicals into the air that disproportionately poison low-income communities of color, like those in “Cancer Alley.”
This is a problem that stretches far beyond the humble poo bags: Hundreds of companies now sell everything from clothes to shoes to shampoo bottles on the boast that they’re made from recycled plastics. Yet “by feigning ‘recycling’ (really, downcycling) of plastic pollution, companies can divert attention from their role in perpetuating this crisis while pulling in profits,” stresses the advocacy group Plastic Pollution Coalition. Recycled plastic can be just another smokescreen when what’s really needed is a reduction of single-use plastics altogether.
But it was reducing single-use plastics that got me into this whole mess in the first place.
In March 2020, a month when nothing else of note was happening, New York City banned single-use carryout plastic bags, joining San Francisco and a number of other towns around the country. But like many pet owners, grocery store plastic bags had been our go-to litter scooping bags. As we became more conscious of single-use plastics in some parts of our lives, it led us to buy … a bunch of single-use plastics to use for our pets.
As the pandemic wore on, my husband and I eventually decided to fly across the country with Marinka and Virginia in order to be with our families. There, my stepmother introduced us to a revolutionary new poop bag. It didn’t require the extraction of any new fossil fuels, and while it doesn’t break down in a landfill, it also won’t poison any otters.
The name of this holy grail of poop bags? Trash.
Empty bread bags can become the perfect chutes for scoops of litter. Plastic packaging gets a second life as a final resting place for kitty unmentionables. Bags of dry cat food, once exhausted, can be refilled.
This isn’t a perfect solution, either (for example, “produce bags aren’t engineered to be particularly durable, nor to hold in liquids or odors,” Wirecutter warns with the confidence of experience). But if I’ve learned anything in this mad, scatological journey, it’s that there is no perfect solution. What satisfies one person’s environmental concerns — about greenhouse gas emissions, fossil fuel extraction, or waste and pollution — might not satisfy someone else’s. And at a certain point, you have to make a choice, and likely a compromise, and then move on to focusing on the things that make a bigger difference, like what you drive, where you get your power from, or what you eat.
All this is to say, the trash method works for me because it makes single-use plastics destined for the landfill anyway into twice-use plastics. And at least it allows me not to think about cat poop anymore.
I think I’ve done enough of that to last me a lifetime.

On a new report from the Energy Institute, high-stakes legislating, and accelerating nuclear development
Current conditions: Monsoon rains hit the southwestern U.S., with flash floods in Roswell, New Mexico, and flooding in El Paso, Texas • The Forsyth Fire in Utah has spread to 9,000 acres and is only 5% contained • While temperatures are falling into the low 80s in much of the Northeast, a high of 96 degrees Fahrenheit is forecast for Washington, D.C., where Republicans in the Senate seek to finish their work on the “One Big, Beautiful Bill.”
The world used more of just about every kind of energy source in 2024, including coal, oil, gas, renewables, hydro, and nuclear, according to the annual Statistical Review of World Energy, released by the Energy Institute. Here are some of the key numbers from the report:
You can read the full report here.
Virginia Republican Jen Kiggans is a vice chair of the Conservative Climate Caucus and a signatory of several letters supporting the preservation of clean energy tax credits in the Inflation Reduction Act, including one letter she co-authored with Pennsylvania’s Brian Fitzpatrick criticizing the House reconciliation bill’s rough approach to slashing the credits. On Wednesday, however, she said on X that the Senate language “responsibly phases out certain tax credits while preserving American investment and innovation in our energy sector.”
The Senate is still pushing to have the reconciliation bill on President Trump’s desk by July 4, and is expected to work through the weekend to get it done. But as Sahil Kapur of NBC News reported Wednesday, House and Senate leaders have been attempting to hash out yet another version of the bill that could pass both chambers quickly, meaning the legislation is still very much in flux.
Shell is in early talks to acquire fellow multinational oil giant BP, the Wall Street Journal reported. While BP declined to comment to the Journal, Shell called the story “market speculation” and said that “no talks are taking place.”
BP is currently valued at $80 billion, which would make a potential tie-up the largest corporate oil deal since the Exxon Mobil merger, according to the Journal.
Both Shell and BP have walked back from commitments to and investments in decarbonization and green energy in recent months. BP said in September of last year that it would divest from its U.S. wind business, while Shell said in January that it would “pause” its investment in the U.S. offshore wind industry and took an accompanying charge of $1 billion.
The combined company would be better positioned to compete with supermajors like Exxon, which is now worth over $450 billion, while Shell and BP have a combined valuation around $285 billion.

Three Mile Island Unit 1 will restart a year early, its owner Constellation said Wednesday. When Constellation and Microsoft announced the plan to restart the nuclear facility last fall they gave a target date of 2028. More recently, however, PJM Interconnection, the interstate electricity market that includes Pennsylvania, approved a request made from the state’s governor, Josh Shapiro, to fast-track the plant’s interconnection, the company said, meaning it could open as soon as 2027.
Constellation reported “significant progress” on hiring and training new workers, with around 400 workers either hired or due to start new jobs soon. “We’re on track to make history ahead of schedule, helping America achieve energy independence, supercharge economic growth, and win the global AI race,” Constellation’s chief executive Joe Dominguez said.
The Chinese electric carmarker BYD is addressing rising inventory and lower prices by cutting back its production plans. The company “has slowed its production and expansion pace in recent months by reducing shifts at some factories in China and delaying plans to add new production lines,” Reuters reported.
The slowdown comes “as it grapples with rising inventory even after offering deep price cuts in China's cutthroat auto market,” according to the Reuters report.
In 2024, BYD beat out Tesla in annual sales, with over 4 million cars sold, for a total annual revenue over $100 billion. Tesla’s revenue was just short of $100 billion last year.
While BYD’s factories may be slowing down, it is still looking to expand, especially overseas. In April, more than 7,000 BYD battery electric cars were registered in Europe, according to Bloomberg. This more-than-doubling since last year slingshotted BYD past Tesla on the continent, where its sales have fallen by almost 50%.
“Where does the power sector go from here?” an audience member asked at our exclusive Heatmap subscriber event in New York on Wednesday, referring to a potential future without the Inflation Reduction Act. “Higher costs,” Emily Pontecorvo answered. There is one potential bright spot, however, as Robinson Meyer explained: “If I were a Democrat considering running an affordability campaign or a cost-of-living campaign in ’26 or ’28, there’s lots of openings to talk about clean energy — the policy that’s happening right now — utility rates, and energy affordability.”
The science is still out — but some of the industry’s key players are moving ahead regardless.
The ocean is by far the world’s largest carbon sink, capturing about 30% of human-caused CO2 emissions and about 90% of the excess heat energy from said emissions. For about as long as scientists have known these numbers, there’s been intrigue around engineering the ocean to absorb even more. And more recently, a few startups have gotten closer to making this a reality.
Last week, one of them got a vote of confidence from leading carbon removal registry Isometric, which for the first time validated “ocean alkalinity enhancement” credits sold by the startup Planetary — 625.6 to be exact, representing 625.6 metric tons of carbon removed. No other registry has issued credits for this type of carbon removal.
When the ocean absorbs carbon, the CO2 in the air reacts with the water to form carbonic acid, which quickly breaks down into hydrogen ions and bicarbonate. The excess hydrogen increases the acidity of the ocean, changing its chemistry to make it less effective at absorbing CO2, like a sponge that’s already damp. As levels of atmospheric CO2 increase, the ocean is getting more acidic overall, threatening marine ecosystems.
Planetary is working to make the ocean less acidic, so that it can take in more carbon. At its pilot plant in Nova Scotia, the company adds alkalizing magnesium hydroxide to wastewater after it’s been used to cool a coastal power plant and before it’s discharged back into the ocean. When the alkaline substance (which, if you remember your high school chemistry, is also known as a base) dissolves in the water, it releases hydroxide ions, which combine with and neutralize hydrogen ions. This in turn reduces local acidity and raises the ocean’s pH, thus increasing its capacity to absorb more carbon dioxide. That CO2 is then stored as a stable bicarbonate for thousands of years.
“The ocean has just got such a vast amount of capacity to store carbon within it,” Will Burt, Planetary’s vice president of science and product, told me. Because ocean alkalinity enhancement mimics a natural process, there are fewer ecosystem concerns than with some other means of ocean-based carbon removal, such as stimulating algae blooms. And unlike biomass or soil-related carbon removal methods, it has a very minimal land footprint. For this reason, Burt told me “the massiveness of the ocean is going to be the key to climate relevance” for the carbon dioxide removal industry as a whole.
But that’s no guarantee. As with any open system where carbon can flow in and out, how much carbon the ocean actually absorbs is tricky to measure and verify. The best oceanography models we have still don’t always align with observational data.
Given this, is it too soon for Planetary to issue credits? It’s just not possible right now for the startup — or anyone in the field — to quantify the exact amount of carbon that this process is removing. And while the company incorporates error bars into its calculations and crediting mechanisms, scientists simply aren’t certain about the degree of uncertainty that remains.
“I think we still have a lot of work to do to actually characterize the uncertainty bars and make ourselves confident that there aren’t unknown unknowns that we are not thinking about,” Freya Chay, a program lead at CarbonPlan, told me. The nonprofit aims to analyze the efficacy of various carbon removal pathways, and has worked with Planetary to evaluate and inform its approach to ocean alkalinity enhancement.
Planetary’s process for measurement and verification employs a combination of near field observational data and extensive ocean modeling to estimate the rate, efficiency, and permanence of carbon uptake. Close to the point where it releases the magnesium hydroxide, the company uses autonomous sensors at and below the ocean’s surface to measure pH and other variables. This real-time data then feeds into ocean models intended to simulate large-scale processes such as how alkalinity disperses and dissolves, the dynamics of CO2 absorption, and ultimately how much carbon is locked away for the long-term.
But though Planetary’s models are peer-reviewed and best in class, they have their limits. One of the largest remaining unknowns is how natural changes in ocean alkalinity feed into the whole equation — that is, it’s possible that artificially alkalizing the ocean could prevent the uptake of naturally occurring bases. If this is happening at scale, it would call into question the “enhancement” part of alkalinity enhancement.
There’s also the issue of regional and seasonal variability in the efficiency of CO2 uptake, which makes it difficult to put any hard numbers to the efficacy of this solution overall. To this end, CarbonPlan has worked with the marine carbon removal research organization [C]Worthy to develop an interactive tool that allows companies to explore how alkalinity moves through the ocean and removes carbon in various regions over time.
As Chay explained, though, not all the models agree on just how much carbon is removed by a given base in a given location at a given time. “You can characterize how different the models are from each other, but then you also have to figure out which ones best represent the real world,” she told me. “And I think we have a lot of work to do on that front.”
From Chay’s perspective, whether or not Planetary is “ready” to start selling carbon removal credits largely depends on the claims that its buyers are trying to make. One way to think about it, she told me, is to imagine how these credits would stand up in a hypothetical compliance carbon market, in which a polluter could buy a certain amount of ocean alkalinity credits that would then allow them to release an equivalent amount of emissions under a legally mandated cap.
“When I think about that, I have a very clear instinctual reaction, which is, No, we are far from ready,”Chay told me.
Of course, we don’t live in a world with a compliance carbon market, and most of Planetary’s customers thus far — Stripe, Shopify, and the larger carbon removal coalition, Frontier, that they’re members of — have refrained from making concrete claims about how their voluntary carbon removal purchases impact broader emissions goals. But another customer, British Airways, does appear to tout its purchases from Planetary and others as one of many pathways it’s pursuing to reach net zero. Much like the carbon market itself, such claims are not formally regulated.
All of this, Chay told me, makes trying to discern the most responsible way to support nascent solutions all the more “squishy.”
Matt Long, CEO and co-founder of [C]Worthy, told me that he thinks it’s both appropriate and important to start issuing credits for ocean alkalinity enhancement — while also acknowledging that “we have robust reason to believe that we can do a lot better” when it comes to assessing these removals.
For the time being, he calls Planetary’s approach to measurement “largely credible.”
“What we need to adopt is a permissive stance towards uncertainty in the early days, such that the industry can get off the ground and we can leverage commercial pilot deployments, like the one that Planetary has engaged in, as opportunities to advance the science and practice of removal quantification,” Long told me.
Indeed, for these early-stage removal technologies there are virtually no other viable paths to market beyond selling credits on the voluntary market. This, of course, is the very raison d’etre of the Frontier coalition, which was formed to help emerging CO2 removal technologies by pre-purchasing significant quantities of carbon removal. Today’s investors are banking on the hope that one day, the federal government will establish a domestic compliance market that allows companies to offset emissions by purchasing removal credits. But until then, there’s not really a pool of buyers willing to fund no-strings-attached CO2 removal.
Isometric — an early-stage startup itself — says its goal is to restore trust in the voluntary carbon market, which has a history of issuing bogus offset credits. By contrast, Isometric only issues “carbon removal” credits, which — unlike offsets — are intended to represent a permanent drawdown of CO2 from the atmosphere, which the company defines as 1,000 years or longer. Isometric’s credits also must align with the registry’s peer-reviewed carbon removal protocols, though these are often written in collaboration with startups such as Planetary that are looking to get their methodologies approved.
The initial carbon removal methods that Isometric dove into — bio-oil geological storage, biomass geological storage, direct air capture — are very measurable. But Isometric has since branched beyond the easy wins to develop protocols for potentially less permanent and more difficult to quantify carbon removal methods, including enhanced weathering, biochar production, and reforestation.
Thus, the core tension remains. Because while Isometric’s website boasts that corporations can “be confident every credit is a guaranteed tonne of carbon removal,” the way researchers like Chay and Long talk about Planetary makes it sound much more like a promising science project that’s being refined and iterated upon in the public sphere.
For his part, Burt told me he knows that Planetary’s current methodologies have room for improvement, and that being transparent about that is what will ultimately move the company forward. “I am constantly talking to oceanography forums about, Here’s how we’re doing it. We know it’s not perfect. How do we improve it?” he said.
While Planetary wouldn’t reveal its current price per ton of CO2 removed, the company told me in an emailed statement that it expects its approach “to ultimately be the lowest-cost form” of carbon removal. Burt said that today, the majority of a credit’s cost — and its embedded emissions — comes from transporting bases from the company’s current source in Spain to its pilot project in Nova Scotia. In the future, the startup plans to mitigate this by co-locating its projects and alkalinity sources, and by clustering project sites in the same area.
“You could probably have another one of these sites 2 kilometers down the coast,” he told me, referring to the Nova Scotia project. “You could do another 100,000 tonnes there, and that would not be too much for the system, because the ocean is very quickly diluted.”
The company has a long way to go before reaching that type of scale though. From the latter half of last year until now, Planetary has released about 1,100 metric tons of material into the ocean, which it says will lead to about 1,000 metric tons of carbon removal.
But as I was reminded by everyone, we’re still in the first inning of the ocean alkalinity enhancement era. For its part, [C]Worthy is now working to create the data and modeling infrastructure that startups such as Planetary will one day use to more precisely quantify their carbon removal benefits.
“We do not have the system in place that we will have. But as a community, we have to recognize the requirement for carbon removal is very large, and that the implication is that we need to be building this industry now,” Long told me.
In other words: Ready or not, here we come.
On mercury rising, climate finance, and aviation emissions
Current conditions: Tropical Storm Andrea has become the first named Atlantic storm of 2025 • Hundreds of thousands are fleeing their homes in southwest China as heavy rains cause rivers to overflow • It’s hot and humid in New York’s Long Island City neighborhood, where last night New York City mayoral candidate Zohran Mamdani delivered his victory speech after defeating former governor and longtime party power broker Andrew Cuomo in the race’s Democratic primary.
The brutal heat dome baking the eastern half of the United States continues today. Cooler weather is in the forecast for tomorrow, but this heat wave has broken a slew of temperature records across multiple states this week:
In Washington, D.C., rail temperatures reached a blistering 135 degrees, forcing the city’s Metro to slow down train service. Meanwhile, in New Jersey, the heat sickened more than 150 people attending a high school graduation ceremony. As power demand surged, the Department of Energy issued an energy emergency in the Southeast to “help mitigate the risk of blackouts.”
As Heatmap’s Matthew Zeitlin pointed out on Tuesday, in terms of what is on the grid and what is demanded of it, this may be the easiest summer for a long time. “Demands on the grid are growing at the same time the resources powering it are changing,” Zeitlin writes. “Electricity load growth is forecast to grow several percent a year through at least the end of the decade. At the same time, aging plants reliant on oil, gas, and coal are being retired (although planned retirements are slowing down), while new resources, largely solar and batteries, are often stuck in long interconnection queues — and, when they do come online, offer unique challenges to grid operators when demand is high.”
A group of 21 Democrat-led states including New Jersey, Massachusetts, New York, Arizona, and California, is suing the Trump administration for cutting billions of dollars in federal funding, including grants related to climate change initiatives. The lawsuit says federal agencies have been “unlawfully invoking a single subclause” to cancel grants that the administration deems no longer align with its priorities. The clause in question states that federal agencies can terminate grants “pursuant to the terms and conditions of the federal award, including, to the extent authorized by law, if an award no longer effectuates the program goals or agency priorities.” The states accuse the administration of leaning on this clause for “virtually unfettered authority to withhold federal funding any time they no longer wish to support the programs for which Congress has appropriated funding.”
The rollback has gutted projects across states and nonprofits that support diversity, equity, and inclusion, as well as climate change preparation programs and research. The states say the clause is being used unlawfully, and hope a judge agrees. “These cuts are simply illegal,” said New York Attorney General Letitia James. “Congress has the power of the purse, and the president cannot cut billions of dollars of essential resources simply because he doesn’t like the programs being funded.”

A brief update from the Bonn Climate Change Conference in Germany: A group of 44 “Least Developed Countries” have called for rich countries to triple the financing goal for climate change adaptation by 2030 compared to 2022 levels. The current target sits at $40 billion a year by 2025, a number set back in 2021 at COP26. According toClimate Home News, tripling the financing goal on 2022 levels would bring in a little less than $100 billion annually. That’s far short of the $160 billion to $340 billion that the United Nations estimates will be needed by 2030. The Indian Express also reports that developing countries have “managed to force a reopening of discussions on the obligations of developed nations to ‘provide’ finance, and not just make efforts towards ‘mobilising’ financial resources, for climate action.” The issue will also be discussed at COP30 in Brazil later this year. The Bonn conference has been running since June 16 and ends tomorrow.
In the UK, aviation is now a bigger source of greenhouse gas emissions than the power sector, according to a new report from the Climate Change Committee. The independent climate advisors say that demand for leisure travel is boosting demand for international flights, and “continued emissions growth in this sector could put future targets at risk.” Meanwhile, the UK power sector has been rapidly decarbonizing, and is now the sixth largest source of emissions. (In the U.S., electricity production is the second-largest source of emissions, behind transportation.) The report also found that heat pump installations increased by 56% in 2024, and that nearly 20% of new vehicles sold were electric. UK emissions were down 50% last year compared to 1990.
The committee applauded the progress but urged more action from the government to cut electricity prices to help speed up the transition to clean technologies. “Our country is among a leading group of economies demonstrating a commitment to decarbonise society,” said Piers Forster, interim chair of the committee. “This is to be celebrated: delivering deep emissions reduction is the only way to slow global warming.”
Voters in North Carolina want Congress to leave the Inflation Reduction Act well enough alone, a new poll from Data for Progress finds. The survey, which asked North Carolina voters specifically about the clean energy and climate provisions in the bill, presented respondents with a choice between two statements: “The IRA should be repealed by Congress” and “The IRA should be kept in place by Congress.” (“Don’t know” was also an option.) The responses from voters broke down predictably along party lines, with 71% of Democrats preferring to keep the IRA in place compared to just 31% of Republicans, with half of independent voters in favor of keeping the climate law. Overall, half of North Carolina voters surveyed wanted the IRA to stick around, compared to 37% who’d rather see it go — a significant spread for a state that, prior to the passage of the climate law, was home to little in the way of clean energy development.
North Carolina now has a lot to lose with the potential repeal of the Inflation Reduction Act, as Heatmap’s Emily Pontecorvo has pointed out. The IRA brought more than 17,000 jobs to the state, along with $20 billion in investment spread out over 34 clean energy projects. Electric vehicle and charging manufacturers in particular have flocked to the state, with Toyota investing $13.9 billion in its Liberty EV battery manufacturing facility, which opened this past April.
As a fragile ceasefire between Israel and Iran takes hold, oil prices are now lower than they were before the conflict began on June 13.
