The results of Heatmap’s very first insiders survey.

Most climate insiders don’t expect the Inflation Reduction Act to get repealed. They don’t foresee the world’s temperature rising more than 3 degrees Celsius by 2100, and they are bullish on hot rocks and geothermal.
Those are the findings from our exclusive — and highly unscientific — survey of climate and decarbonization insiders. Over the past few weeks, Heatmap has queried more than 30 climate insiders across policy, science, technology, and economics, including high-profile energy entrepreneurs, high-rolling “climate tech” venture capitalists, and some high-ranking (and very-soon-to-be-former) Biden officials.
We wanted to know what they’re thinking about the era to come — and about how they would handle some of the biggest questions that plagued climate policy during the Biden era: Will Congress pass permitting reform? Is there a trade-off between developing artificial intelligence and decarbonizing the power grid? And how would you balance China’s dominance over certain clean technologies — and the need for the American economy, and the American military, to stay competitive? We got a lot of answers. Here’s what they told us…
Folks were bullish about geothermal, hot rocks, and batteries. Five respondents mentioned Fervo, the advanced geothermal company that borrows techniques (and workers) from the fracking industry. Three said Form Energy, which makes cheap iron-air batteries for the power grid; several mentioned Rondo or Antora, which produce thermal batteries that can store and release huge amounts of heat. “The real answer I can't disclose yet, but there is the one,” said a prominent climate tech investor. Get real, replied a policy researcher: The only “climate tech” company today with a claim to be the most important is Chinese EV juggernaut BYD.
Really good heat pumps, said the most respondents, tied with any way to make chemicals, liquid fuels, or plastics in a low-carbon way. A close second: Virtually anything that could be used to decarbonize apartment or multifamily residential buildings. “From the perspective of an apartment-dweller in a large shared building, it seems almost impossible to get buy-in for building decarbonization,” said one climate scientist. “I know ‘convince a landlord/co-op/condo board to do something’ doesn't have a technological solution, but it's the biggest stumbling block.”
Brown hydrogen, green hydrogen, blue hydrogen — it doesn’t matter, throw them all out. Sixteen percent of respondents, including an energy researcher and a climate tech VC, wanted to ditch “the hydrogen rainbow.” “Tipping points,” said one climate scientist. Another climate scientist told us: “Climate crisis, climate emergency, global heating: anything that implies the primary impediment to cutting emissions is scientists using the wrong word.” “Three pillars,” said a former Biden official. “Levelized cost of energy, or LCOE,” said a climate entrepreneur. “It so oversimplifies the way the grid actually works and how electricity is valued that it does more harm than good.” “Carbon accounting, carbon footprint, and anything else that makes us think our current emissions are the most important thing to our future success,” said another VC.
Nearly two-thirds of respondents, spanning every field we queried, said that AI and data center growth isn’t hindering decarbonization … yet. And among the 35% of insiders who answered yes, most also framed their concerns in future terms. “Perhaps not at present, nor over the last few years, but the trajectory is alarming and I do believe they could derail emissions goals at scale within the next 5 years,” said one climate scientist. “Seems like there are plenty of reports of new gas capacity being added,” agreed another researcher. “On the other hand … we would need so much more capacity for hydrogen, electrification of transport and homes, etc., so I'm not sure why we are so worried about AI in the scheme of all the new and upcoming needs for electricity.” “Hot take: AI isn't worried about energy, but energy is worried about AI,” interjected a climate tech VC.
Exactly half of our insiders said: Nope, this tradeoff almost never actually exists. Among the other half, insiders said policymakers should be pragmatic, and only a few said that they should focus on cutting emissions at all costs. “They should do whatever is required to maintain and accelerate political ambition on climate,” said a climate philanthropist. “They should have prioritized social justice issues less,” said one climate tech CEO. “It is never a fair commercial fight with China since our companies are always up against the Chinese state,” said a former U.S. government official. “But it would be a big mistake to allow China to dominate green tech and supply chains — as they would like to do — since that would create an untenable dependence on a country that never hesitates to weaponize its economic advantage. But the imperative to decarbonize is massively important.”
Forty-five percent of respondents said that yes, we should let the EV imports rip. A few researchers and former Biden officials added a twist: “Yes, but only if they are made in the USA.” Others thought that the U.S. should import the cars, but only with a carbon adjustment tariff and a huge investment in U.S. EV manufacturing. “If there were CBAM and other tariffs meant to reflect the imbalance of environmental and labor regulations, then yes,” said one VC. “But then the cars wouldn’t be that competitive.” Almost everyone else said no.
NOPE, said 68% of the insiders. (About 17% said yes, and 15% weren’t sure or thought a minority of the grants might get clawed back.) “I expect it will go after some provisions, but there is quite a bit in the IRA that will be very difficult to repeal since large-scale clean energy investments have been made, and a majority of those in red states whose politicians will not want to give them up,” said one former U.S. official. “A lot of money has already gone out, so I'm guessing the money for EJ initiatives and communities is most at risk,” said a climate researcher. One Biden official threw down the gauntlet: “None of the measures will get repealed. Even unspent money will largely be safe.”
YES, said 59% of insiders. NO, said 41%. “I hope not. That bill sucked,” said a researcher.
“Europe pushing ahead with nuclear energy. Paradigm shifts are possible,” said one energy researcher. “Trump's picks for Energy and Interior could have been much worse,” said another. A former Biden official said that the American Petroleum Institute’s decision to back the IRA was a good sign — and an economist noted the dozen House Republicans opposing repeal encouraged him, too. “Corporates’ willingness to procure clean electrons at a ‘green premium’ for their AI energy demands,” said a climate tech VC.
“Oh dear,” said one researcher. The average of insiders’ answers were 2.8 degrees Celsius, with the highest guesses going up to 3.5 degrees Celsius. A few respondents said 2 degrees Celsius, but only because they thought humanity will have the ability to modulate temperatures by then. “If we don't do anything, I think 3 to 4 degrees,” said another. “We will be able to control global temperatures before we achieve net zero, so by 2100 if civilization is still healthy we will have settled at some optimal temperature,” said another VC.
Some experts believe that the world’s biggest polluter has already hit peak greenhouse gas emissions. Our panelists weren’t so sure: 30% of respondents each said that China’s pollution would peak in the 2020s, 2030s, and 2040s, respectively. The remainder would look to 2050 or beyond.
Unlike China, America’s emissions have already peaked. (They did that more than a decade ago, around the Great Recession.) So U.S. policy makers now plan for the arrival of net zero, the hypothesized future date when the American economy will emit roughly as much climate pollution as it absorbs. While respondents were split on when that might happen, most see it emerging in the 2050s or 2060s.
It’s time to focus on climate impacts, which are coming regardless of what happens with emissions, said many. “In the age of Trump, we need to think more about resilience. Preparing ourselves to deal with the weather variability we are seeing already (e.g., California fires, Florida hurricanes, Colorado River drought years) will put us in a much better position to deal with climate change,” a climate scientist added. “I think 2025 is a year that we will start to see adaptation technologies/approaches and solar geoengineering start playing much larger roles in the climate response policy portfolio,” one researcher-activist told us.
But the climate tech industry is upbeat: “It's an optimistic time for climate tech,” one climate tech CEO said. “The return of climate-tech funding in the last 5 years has allowed a lot of ideas to be tried, and there is now enough data on what is working and what is not. The good news is that there is more than enough in the ‘working’ column to move full speed ahead.” And a climate VC agreed: “The second Trump administration will see more acceleration for industrial climate tech than the Biden years.” “The United States has better technology than any country in the world,” said a Biden official. “Biden’s policies combined with America First messaging will forever dispel the myth that China has any sort of technology lead by 2028 … emissions will go down faster during the Trump administration than they did in the Biden administration because deployment has been positioned to reach all time highs starting in 2026.”
Yet some saw risks for the world ahead. “The most important stories for climate action in 2025 have less to do with climate and more to do with geoeconomic competition,” said one public policy expert. Trade fragmentation may drive prices up and slow innovation, greatly delaying technology diffusion and deployment. And there is a major risk of continued or worsened conflict — the greatest risk being China's positioning vis a vis the Pacific and Taiwan.”

Investment in zero-carbon energy and transportation surged this spring, driven by consumer EV and battery buying.
This is an edition of Heatmap Daily, an evening review of the day’s news written by our executive editor. Sign up for it here.
Ready to be surprised? Clean energy and transportation investment surged in the second quarter of this year, rising to more than $75 billion in total, according to new data released earlier this week.
In fact, this spring was the second biggest quarter for U.S. clean investment in nominal terms since at least 2018, when data started to be kept. More than 5% of overall investment in the United States went into a clean energy or transportation industry.
That’s according to the Clean Investment Monitor, a joint project of the MIT Center for Energy and Environmental Policy Research and the Rhodium Group, a private research firm. The monitor tracks nationwide investment across a number of sectors that make up the new electricity economy, including critical mineral refining, battery manufacturing, solar and wind installation, and electric vehicle and heat pump purchases by consumers (among other variables).
Outside of a promising headline number, the story is a mixed one. Investment in America’s clean manufacturing sector started growing again last quarter after falling for 18 months; it remains about 24% below where it was a year earlier, according to the project. The new growth came overwhelmingly from investment in the EV supply chain — defined as “critical minerals, batteries, vehicle assembly, and charging equipment” — driving a staggering 88% of all clean manufacturing investment. That subsector alone made up more than 9% of all U.S. clean investment.
The more interesting story — and what leaps out from the chart — is that retail activity drove the spring resurgence. High gasoline prices helped here, pushing consumers to buy all-electric and plug-in hybrid vehicles in larger numbers. (Rivian, Tesla, and other automakers started to see an EV rebound last quarter, too, after Republicans ended EV incentives in 2025.) But the real boom came in residential batteries, which surged to an all-time high of $11 billion in quarterly sales. Consumer activity hasn’t made up such a large share of national clean investment since 2023.
This trend wasn’t just happening in the United States. We’ve talked a lot at Heatmap about whether the Strait of Hormuz crisis will drive a clean energy boom. But it's now clear the oil price shock really did encourage global EV adoption. Some 50 countries set new EV sales records in 2026’s second quarter, according to Kelley Blue Book. India, Brazil, and Australia all set record highs. That's a lot of demand destruction.
As costs rise, more proceeds from the Regional Greenhouse Gas Initiative are going to direct bill relief.
A carbon price can be a tough sell when electricity costs are rising.
That’s what governors up and down the eastern seaboard are facing as they decide what to do with revenues from the Regional Greenhouse Gas Initiative, an 11-state cap-and-trade program for the electricity sector that operates from Virginia to Maine.
In Virginia and New Jersey, two states where Democratic governors won last year amidst a maelstrom of concern about rising electricity prices, the program has been at least partially reoriented around putting dollars back into the pockets of ratepayers.
Virginia only recently rejoined the group this year after having left under the leadership of Republican Glenn Youngkin in 2023. When Virginia was last a member of RGGI, the proceeds from the auctions for emissions allowances largely went to an energy efficiency program for low-income households and a flood resilience fund. Today, having rejoined RGGI, some 45% of the revenue will be earmarked for rate relief, thanks to a budget amendment passed in June.
In New Jersey, meanwhile, Governor Mikie Sherrill has used money raised through to help fulfill the rate freeze pledge on which she centered her campaign for Drumthwacket by directly reducing bills.
Conservatives in RGGI states have for years tried to make a stink about the up-front costs it imposed on ratepayers. Now as electricity costs balloon, Democratic governors and state legislatures are looking to RGGI to help balance their emissions goals and efforts to keep electricity bills under control.
In New Hampshire, for instance, the most conservative state to be a consistent RGGI member, nearly all the state’s proceeds from the program now go to rate relief, compared to about three-quarters historically. In its latest report on how RGGI funds get used, the organization reported that in 2024, the last year for which comprehensive data is available, some 23% of RGGI proceeds went to direct bill assistance, compared to 16% over the 17-year lifetime of the system.
“The affordability narrative is the leading political narrative of 2026. And the albatross around the neck of carbon pricing has been that it’s going to raise energy prices,” Dallas Burtraw, a senior fellow at Resources for the Future, told me.
Seen holistically, Burtraw told me, “carbon pricing is built for affordability.” That’s because, one, economists generally consider carbon pricing the cheapest and most efficient way to hit a given emissions reduction goal (assuming, that is, that you want to reduce emissions in the first place), and secondly because the proceeds from the carbon price can be invested and distributed in ways that mitigate price hikes.
“Carbon pricing raises tremendous proceeds, and the question comes down to the distributional impacts of carbon pricing. It always comes down to how you use those carbon proceeds,” Burtraw told me.
The current pressure for rate relief comes as RGGI prices have risen as the same time electricity prices up and down the East Coast are at or near all-time highs. The clearing price in the latest quarterly auction for carbon dioxide allowances was $35 per ton, the highest price in the history of the program, bringing in some $642 billion to be distributed among the states. By contrast, the third quarter auction in 2025 had a clearing price of $19.63 and raised some $300 million.
At the same time, electricity bills have risen across the RGGI system, including an 18.5% rise in New Jersey by 12.5% rise in New Hampshire just over the past year, according to Heatmap and MIT’s Electricity Price Hub.
Because every state in the RGGI system besides Virginia operates in a restructured wholesale electricity market, it’s hard to say exactly how much RGGI prices affect ratepayer bills. In Virginia, Dominion, the dominant utility, has requested permission for a rider on bills of $10 to $13 per month, compared to monthly added costs under $3 when Youngkin began the process of withdrawing Virginia from the system in 2022.
In a New Jersey regulatory filing, meanwhile, the state’s Board of Public Utilities recommended using RGGI proceeds to fund $150 million of rate relief for moderate- and low-income households that Sherrill announced in June, citing an update to the state’s three-year strategic plan for RGGI that directly the NJBPU “to provide direct bill credits on residential energy bills for NJ’s most vulnerable residents.” There is precedent for this in the Garden State: In 2025 Governor Phil Murphy helped deliver rate relief by shifting some RGGI money around.
The trend toward using RGGI funds for rate relief has caused disquiet among environmental groups that support carbon pricing and want to see the dollars largely go to energy efficiency programs, not ratepayers.
In 2025, a coalition of Virginia environmental groups that supported rejoining RGGI called for revenue to go to the “low-income energy efficiency fund and the Community Flood Preparedness Fund.” The Flood Preparedness Fund issues grants to local governments for flood mitigation and resiliency projects, while the energy efficiency programs fund things like home weatherization.
“The case we’ve made to our environmental advocates in Virginia is that we have taken 45% towards RGGI credits, but we’ve left 55% of the revenue. That leaves each of the programs with record levels of funding,” Josephus Allmond, Virginia’s chief energy officer, told me, referring to the flood and energy efficiency programs that have historically been funded by RGGI.
“We were able to take what could have been a pretty negative impact to residential customer bills and turn it into something we can basically hold customers harmless.”
While the Natural Resources Defense Council has said it supports temporary rate relief to low-income ratepayers, it also has also mounted a defense of using RGGI revenues “to fund energy and environmental programs.”
“Several states are using larger amounts of program proceeds to provide households with bill credits or rebates that immediately lower monthly electricity bills, which means less investment in programs that provide long-term benefits,” Jo Gardias and Dawone Robinson wrote for the NRDC.
To me, Gardias framed the debate between energy efficiency programs and bill credits as between up-front and long-term benefits.
“Energy efficiency programs not only save the households that are getting the upgrade money, but every other customer through avoided transmission and distribution and generation costs,” Gardias told me. “On the far end there’s energy efficiency where you’re getting lifetime savings, on the shorter or more immediate end there’s the bill credit on energy savings.”
RGGI itself has estimated that every $1 of investments funded by the auction results in a lifetime bill savings of just over $4. In 2024 alone, RGGI claims that investments “are associated with approximately $363.9 million in annual energy bill savings and $2.6 billion in lifetime bill savings.”
“The question of how you spend proceeds is a large question of tradeoffs,” Gardias said. “What we’re seeing now is that because we have price spikes that are happening from data centers and other factors, there’s more interest in spending money on bill credits that provide immediate relief.”
Of course, this is the dilemma with all climate policy. The costs are immediate and upfront, while the benefits accrue over time and are more difficult to attribute to any one program or investment.
“There’s a lot of priorities for ways that you should use carbon proceeds to address the challenges of climate change,” Burtraw said. “But in 2026, given the affordability narrative and the populist sentiment in politics today, it makes sense to use carbon proceeds to reduce electricity prices.”
While an economist could draw up a cost benefit analysis that shows any number of uses of the proceeds could be more efficient for the economy or the environment — using the money to reduce taxes on investment, say, or using the money to fund energy efficiency programs — any of those would assume certain baseline of support for carbon pricing in the first place.
“For 25 years we’ve argued about this with the expectation that carbon pricing was inevitable because it was so much more efficient than any other type of approach. But we’ve seen after 25 years that carbon pricing is not inevitable,” Burtraw said. “We have to face the realities of what it takes to make it possible to do carbon pricing.”
Misan Lychee is made with “some” carbon dioxide captured “directly from the air,” along with 14.6 grams of added sugar.
I believe life should be a little bit silly, which is why I’m a sucker for a gimmick. A hotel just for napping? Sign me up. A “convenience store” full of items made of felt? I now own a bag of inedible Fritos. Hot sauce packaged to look like dynamite? Cute, add to cart.
And when I found out that you can buy soda carbonated with CO2 obtained via direct air capture, I said, Take my sixteen American dollars and put it on ice.
Misan Lychee (which yes, only comes in lychee flavor “at the moment”) represents the distant hopes and dreams of DAC. Currently, there isn’t demand for carbon dioxide at direct air capture prices; it’s much, much cheaper just to buy the concentrated byproduct of, say, natural gas- and coal-fired ammonia plants to carbonate your soda than to go through the trouble of sucking the 0.04% of the air that is CO2 out of the atmosphere for a few bubbles. That’s why the carbon removal industry is propped up by offtake agreements and credits, at least until Brutalism comes back in a big way and dramatically increases the demand for concrete manufactured with stored CO2.
Still, that hasn’t stopped companies from trying. You can buy carbon-sequestered beer, DAC vodka, CO2-captured perfume, and recycled-emission yoga pants. But unlike other consumer products that are, in many cases, made from waste gas captured during industrial processes rather than from true atmospheric CO2, Misan claims on the can to be made from “some” carbon dioxide pulled “directly from the air using a technology called direct air capture.” The bottle sports the logo of Bay Area-based AirMyne, a DAC start-up, which, on further investigation, turns out to own Misan.
My order arrived rattling around in a cardboard box, with three of the cans having popped loose from the six-pack in transit. As someone with no impulse control (which, upon reflection, might be related to my love of gimmicks), I immediately opened a can. Over my laptop. We both got drenched by the resulting geyser. CO2’s presence: confirmed.
What happened next was, admittedly, also user error. I took a sip and immediately went, “Yuck, what?” That’s because after a summer of drinking my way through every Waterloo flavor, I was expecting Misan Lychee to be a seltzer, too. Despite its website describing it as a “climate-forward sparkling water,” it is not, and you can taste all 14.6 grams of its added sugar. It has a moderately cloying, perfumy flavor that my dad described as “strawberry, but disturbing?” when I asked him to do a blind taste test. I think it’s perhaps closer in taste to pear, and I remain optimistic that someone who has more free time than me could come up with a recipe to turn it into a “sustainable” spritz.
Actually, to that point — is it sustainable? It notably doesn’t claim to be, and it has its skeptics. Richard Waite of the World Resources Institute pointed out on Bluesky that carbon dioxide is only “sequestered” until it leaves our metabolic system the usual way, via exhalation or burps. Still, his questions about the energy source of AirMyne’s direct air capture — and thus the carbon-emitting or -removing properties of the soda — generated lots of good puns in the replies. “Run out of polar before we run out of Polar” comes to us courtesy of Costa Samaras.
The second Misan Lychee I cracked also soaked me, although I was prepared this time and at least opened it out of range of electronics. I also paid more attention to the can, which has an unusual but not unpleasant matte feel. The list of ingredients on the back seems surprisingly long for the supposed golden age of “gut sodas” that advertise such things as the inclusion of “plant fibers.” Rather than prebiotics, Misan contains “xanthan gum” and an ominous concoction identified as “cloudy agent.”
If Misan isn’t healthier for me or the planet, then what is it for, exactly? I returned to the six lines of all-caps text printed on the front of the can:
Some of the CO2 in this can was pulled directly from the air using a technology called direct air capture (DAC). If scaled, DAC could do more than just carbonate your water. It could remove millions of tons of CO2 from the atmosphere, fighting climate change.
Gimmicks are, ultimately, ways to sell you something. Water gets packaged to look more “manly;” you might buy a Coca-Cola instead of a Pepsi if it has your name on it. But Misan isn’t ultimately selling itself with the promise of bubbles brought to you by DAC. It’s the other way around: Misan is the marketing vehicle for AirMyne. They want you to drink the DAC Kool-Aid.
Will I buy Misan Lychee again? Not likely: I have De La Calle! Mango Chili Mexican sodas to drink, made from the fermented rind of pineapples — BYOCO2, if you will.
Then again, never say never. If I learn about the existence of Misan Chikoo or Misan Pistachio-Rosewater during a weak moment, I’ll probably be down another $16. But I’ll open it over the sink this time.
