Alternative proteins have floundered in the U.S., but investors are leaning in elsewhere.

Vegans and vegetarians rejoiced throughout the 2010s as food scientists got better and better at engineering plant and fungi-based proteins to mimic the texture, taste, and look of meat. Tests showed that even some meat enthusiasts couldn’t tell the difference. By the end of the decade, “fake meat” was booming. Burger King added it to the menu. Investment in the sector topped out at $5.6 billion in 2021.
Those heady days are now over — at least in the U.S. Secretary of Health and Human Services Robert F. Kennedy, Jr. champions a “carnivore diet,” price-conscious Americans are prioritizing affordable calories, and many consumers insist the real thing still simply tastes better. Investment in alternative proteins has fallen each year since 2021, with the industry raising a comparably meager $881 million in 2025.
In China, however, the industry is just starting to pick up steam. Early-stage startups have been popping up ever since the country’s Ministry of Agriculture and Rural Affairs included “future foods” such as lab-grown meat and plant-based eggs in its 2021 – 2025 five-year plan, indicating that these modern proteins will play a role in helping to secure the country’s domestic food supply chain.
“26% of the world’s meat is consumed by China, and about 50% of the world’s seafood,” Albert Tseng, co-founder of the venture firm Dao Foods, which backs Chinese companies developing climate-friendly proteins, told me. And yet the average Chinese consumer still only eats about half as much meat as the typical American, meaning that as the country gets richer, those numbers are only poised to grow. “The history of the world is essentially that as incomes rise, demand for protein also rises,” Tseng said.
But letting the protein patterns of the past dictate the future will have serious implications for the climate. Livestock production accounts for roughly 14% to 18% of global greenhouse gas emissions from things like methane releases and land-use changes. Yet it can seem unthinkable for many consumers to cut back on the foods they love, which is why some of the alternate protein sector’s most well-known companies are aiming to replicate the taste, look, and feel of meat.
That strategy isn’t going to fly in China though, Tseng told me. His goal is to slowly woo Chinese consumers away from meat and dairy with alluring plant-based, fungi-based, and lab-grown alternatives — ideally without customers even realizing what’s happening. For example, one of Dao’s portfolio companies, ZhongGu Mycelium, embeds the “superfood” mycelium — the root-like structure of fungi — into flour, boosting the protein-content and nutritional value of everyday products like dumplings and buns.
“We’re trying to actually crowd out demand for other proteins by infusing staple foods with the superfood ingredients that are more familiar, but also satiate people and provide the nutrition they need,” Tseng explained.
Tseng, a Canadian of Chinese descent, founded Dao Foods in 2018, with the idea that a regionally focused platform would allow him and his portfolio companies to develop deeper insights into the Chinese consumer. One lesson so far: In China, highlighting the health benefits and novelty of new proteins in their own right tends to resonate more than replicating the experience of eating meat or dairy. Dao Foods’ portfolio companies are making everything from coconut milk tea to rice proteins and plant-based hot pot broth — products designed to fit seamlessly into the country’s existing culinary culture without necessarily taking the place of meat.
“Direct replacement is probably not a sound commercial pathway,” Tseng said. Designer proteins command a higher price and are thus largely enjoyed by people explicitly trying to reduce their meat intake, whether for climate, health, or animal welfare reasons. But that conscious consumer segment concerned about the environment or animal rights is essentially nonexistent in China, Tseng told me. Rather, meat is viewed as a sign of status for the country’s growing upper and middle classes.
That cultural mismatch may be part of the reason Beyond Meat floundered when it entered China amidst the COVID lockdowns of 2020, a year after going public with a nearly $4 billion valuation. It finally exited the market early last year, and today its market capitalization is less than $400 million — a roughly 90% decline. Impossible Foods has long planned to launch in China too — the founder told Bloomberg in 2019 that it was “the most important country for our mission” — but that has yet to happen. Impossible CEO Peter McGuinness said last summer that the company was still years away from profitability.
China definitely hasn’t given up on the sector yet — it’s barely even gotten started. The country is now in the process of finalizing its five-year plan for 2026 – 2030, and “future foods” are expected to remain a part of the roadmap. Tseng noted that local mayors who implement the national government’s dictates are already competing to attract alternative protein companies to their regions, betting they’ll become drivers of regional GDP just as solar panel and electric vehicle manufacturers have been. “We’ve moved two or three companies now from one region of China to another because they’ve been interested in developing an area of expertise in sustainable food or future foods,” he told me.
So far, these regional enticements have largely come in the form of non-cash incentives. For example, ZhongGu Mycelium, is moving from Mongolia to the Western China municipality of Chengdu, where it will establish a new mycelium research and development facility and production hub. The move was a no-brainer given that “they were being offered a new factory space predominantly rent free for the first three years,” Tseng told me. Not only that, but the local government is “connecting them with the local business environment and food companies in that area. They’re providing some tax incentives, and they’re providing connections to the local university for research support.”
The U.S. can’t offer this level of state support even in the best of times. And with the current meat-loving administration in office, the likelihood of the alternative proteins market receiving any degree of federal backing is essentially nil. We simply aren’t hearing much these days from some names that were making waves just five years ago.
“A lot of these companies were ahead of consumer demand,” Kim Odhner, the co-founder of the sustainable food venture firm Unovis Asset Management, told me. When he started Unovis in 2018, companies such as Impossible Foods and Beyond Meat — an early Unovis investment — were gaining serious momentum. The firm has thus far weathered the downturn with its broad portfolio of meat and dairy alternatives — which includes an investment in Dao Foods, where it serves as a founding partner and shareholder. But as Odhner told me, “One of the most important lessons is that the whole build it and they will come mentality is very dangerous.” Many of the sector’s anticipated customers — in the U.S. and Europe at least — have yet to show up.
As Odhner prepares to raise a third fund with Unovis, he’s focusing on supporting growth-stage startups with proven technologies and minimal regulatory risk. That mainly includes businesses producing protein-rich ingredients for established food companies to incorporate into their existing product lines. It would be “very difficult,” he told me, for Unovis to raise money for an early-stage alternative protein fund today.
Like Tseng, Odhner thinks the best approach for the industry is to make inroads at the margins. “I don’t see any time in the near future — even in the distant future — where we’re going to be replacing center-of-the-plate steak with a cultivated meat equivalent,” Odhner told me.
Either way, Tseng and Odhner agree that there’s still real potential — and real money — in the sector. In China at least, Tseng thinks alternative proteins could follow in the footsteps of other clean energy industries such as solar panel and EVs that have taken root in the country despite many of their breakthrough innovations originating elsewhere. Drawing a parallel to the rise of Chinese EVs, he said that while outsiders perceived the industry as taking off overnight, its growth was actually a decades-long journey marked by plenty of missteps.
“But then at some point, it hit a tipping point,” Tseng told me. “And then the Chinese government signaled, investors poured in and supported these companies, and then you get BYD.”

Current conditions: Severe thunderstorms are drenching the American South from New Orleans to Virginia Beach • Mount Mayon has forced thousands to evacuate within the Philippines’ Bicol peninsula • Temperatures in Denver are poised to plunge from about 75 degrees Fahrenheit yesterday to 39 degrees today with a chance of snow.

The North American Electric Reliability Corporation, the quasi-governmental watchdog that monitors the health of the power grids that span the United States and Canada, has issued a rare Level 3 warning. The alert, announced Monday, marks only the third time NERC has put out a notice with that degree of severity in its 58-year history. The warning comes on the heels of reports that data centers abruptly went offline in Virginia and Texas, prompting concerns of potential blackouts. “Computational loads, such as data centers, could increase exponentially in the next four years,” NERC said in a draft of the alert, adding that “significant risks” to the power network “need to be addressed through immediate industry action.” Lee Shaver, a senior energy analyst at the Union of Concerned Scientists, told E&E News that NERC’s action was a “big deal.”
The California Energy Commission has issued an administrative investigative subpoena to Golden State Wind seeking documents and information related to the company’s recent deal with the U.S. Department of the Interior to take a payout in exchange for abandoning its offshore wind lease. Last week, the developer announced a deal to scrap its lease in the Morro Bay Wind Energy off the central California coast for $120 million as part of the Trump administration’s efforts to kill off an industry he failed to destroy through regulatory fiat alone. The facility was supposed to be California’s first offshore wind farm, and planned to use floating turbines to account for the steep continental shelf dropoff on the nation’s Pacific Coast. Now the administration’s latest “shady deal” is drawing scrutiny from state regulators. “The Trump Administration is recklessly spending billions of taxpayer dollars on backroom deals that would turn back the clock on innovation,” David Hochschild, the chairman of the California Energy Commission, said in a statement. “Californians deserve immediate answers about the nature of this payout. Taxpayer dollars should be used to build a sustainable energy future, not to pay to make projects disappear.”
Meanwhile, California’s grid operator has switched on a new regional electricity market as part of what E&E News called “a major milestone in the yearslong push to expand energy trading” across the American West. The California Independent System Operator launched its new Extended Day-Ahead Market early Friday morning, allowing California’s investor-owned utilities and the Northwestern giant PacifiCorp, whose coverage area spans two million customers across six states, to trade electricity on the regional market for the first time. “The West is rich with a diverse mix of renewable resources, and this market will capture their potential,” Michael Colvin, director of the California energy program at the Environmental Defense Fund, said in a statement. “Through better sharing of cheap, clean energy beyond state borders, the market will cut household bills, reduce reliance on expensive, polluting fossil plants and build a grid that's bigger than any single extreme weather event.”
For nearly as long as there have been nuclear power plants, there have been thorium bulls insisting the metal is a better fuel than uranium. In most places, the thorium dream faded long ago as ample new sources of uranium were discovered. But China revived the thorium race in 2023, when its experimental molten salt reactor powered by the metal split atoms for the first time. Now the only serious contender in the entire West looking to commercialize thorium is a Chicago-based company taking an unusual approach. Rather than creating a whole new kind of reactor to run on thorium, Clean Core Thorium Energy has designed fuel assemblies that blend thorium with a special kind of uranium fuel and work in existing reactors without any modifications. Clean Core’s technology only works, at least for now, in pressurized heavy water reactors, which make up the bulk of the fleets in Canada and India, though the U.S. has none in operation. But the key verb there is that: It works. On Tuesday, I can exclusively report for this newsletter, Clean Core plans to announce that its patented fuel completed a high burnup irradiation test at Idaho National Laboratory’s Advanced Test Reactor. The fuel burnup represented “more than eight times the typical” output from the traditional uranium fuel used in pressurized heavy water reactors. The latest test “provides meaningful performance data” and demonstrates that Clean Core’s fuel “achieve burnup levels comparable to those seen in PWR fuels while offering improved fuel utilization, enhanced safety characteristics, inherent proliferation resistance, and meaningful reductions in long-lived nuclear spent fuel radioisotopes,” Mehul Shah, Clean Core’s chief executive, told me in a statement. “Our objective has been to introduce thorium into the nuclear fuel cycle in a practical way using existing reactors, and this milestone represents a significant step toward that goal.”
It’s the latest good news for Clean Core. Last month, as I reported for Heatmap, the company inked a deal with the Canadian National Laboratories to manufacture its first commercial fuel assemblies.

In July 2017, South Carolina abandoned its $9 billion expansion of the V.C. Summer Nuclear Station, leaving ratepayers holding the bag and utility executives facing prison time for lying about the project’s viability. Now the pair of Westinghouse AP1000s planned at the site are making a comeback. On Monday, Westinghouse-owner Brookfield Asset Management formed a new joint venture with The Nuclear Company, a reactor construction manager, to work together on building more Westinghouse reactors such as the AP1000 or the smaller version, the AP300. V.C. Summer is the likely first project. “Our team was built on the field of Vogtle and on some of the most complex energy projects in the world,” Joe Klecha, The Nuclear Company’s chief nuclear officer, said in a statement. “We know what it takes to deliver nuclear. What’s been missing is a model that brings together the people, the capabilities, and the capital to do it at speed and scale. That’s what this partnership creates.” The announcement comes as the Trump administration meets with utility executives to discuss funding deals to build the 10 new large-scale reactors President Donald Trump ordered the Department of Energy to facilitate construction on by 2029, as Heatmap’s Robinson Meyer reported. Completing 10 AP1000s would give the U.S. economy a trillion-dollar boost, per a PricewaterhouseCoopers report Westinghouse released in March.
That’s not the only nuclear developer making deals. On Tuesday morning, Blue Energy, another startup focused on serving as a project developer for existing reactor designs, announced a partnership with GE Vernova to work on building the world’s first gas-plus-nuclear plant in Texas. The 2.5-gigawatt project would include GE Vernova’s gas turbines and its BWRX-300 small modular reactors through its joint venture with Hitachi. “Innovative projects like this one will help advance the future of nuclear power and meet the surging demand for electricity,” Scott Strazik, GE Vernova’s chief executive, said in a statement.
Steel, if you’re unfamiliar, is made in two big steps. Traditionally, iron ore is melted down in a coal-fired blast furnace, then forged into steel in a basic oxygen furnace. New plants typically run on something called direct reduced iron, which uses natural gas to turn the ore into iron, then made into steel in an electric arc furnace. The latter process is far cleaner. It can even be green, if the natural gas is swapped for green hydrogen and the electric arc furnace is powered by renewables or nuclear reactors. Nearly 40% of all global clean steel investments to date are hydrogen-powered DRI facilities. That’s according to new data from the Rhodium Group, which released its latest estimates Tuesday. Another 57% of investments are gas-powered DRI plants. While Europe has so far dominated investment into hydrogen DRI, “the region will likely see relatively little demand growth for iron over the coming decades,” the report found. In the fastest growing regions, such as India, Africa, and South America, “most new demand is being met with traditional, fossil-based ironmaking technologies, which risks locking in emissions for decades.” The consultancy’s modeling shows that clean steel supply capacity is on track to exceed demand by between 1.8 and 4.3 times by 2030, “risking a collapse of the nascent industry, where existing projects cannot find buyers and scale production to drive down costs.”
It may be time for a new New Orleans. The city has reached a “point of no return” that will see it surrounded by ocean within decades as climate change worsens. That’s the conclusion of a new paper in the journal Nature Sustainability. “In paleo-climate terms, New Orleans is gone; the question is how long it has,” Jesse Keenan, an expert in climate adaptation at Tulane University and one of the paper’s five co-authors, told The Guardian.
A ubiquitous byproduct of the oil and gas industry just got a green competitor.
The chemicals industry, which accounts for about 5% of global emissions, can seem like a black box. Fossil fuel-based feedstocks go in and out pop plastic toys or agricultural fertilizer or laundry detergent. But most of us don’t understand what happens in between. That’s the part of the supply chain where Trillium Renewable Chemicals is focused, as it scales production of bio-based acrylonitrile, a key chemical intermediate used to make products ranging from carbon fiber aircraft components to plastic Lego bricks and rubber medical gloves.
Though you might not have heard of this mouthful of a chemical, acrylonitrile’s production is a major contributor to the embedded emissions of all the products that it goes into, as it’s typically derived from propylene, a byproduct of the oil and gas industry. “When you look at the lifecycle analysis of these products, the thing that jumps off the page is acrylonitrile dominates that lifecycle,” Trillium’s CEO, Corey Tyree, told me. “It is the number one challenge.”
The startup, which spun out of a Department of Energy-funded nonprofit called the Southern Research Institute, just announced a $13 million Series B round led by HS Hyosung Advanced Materials, alongside the completion of the world’s first demonstration plant for bio-based acrylonitrile. Tyree was determined, he told me, to ensure that the work did not remain just another “research project that goes in the research closet.”
He credits much of Trillium’s progress so far to an intense focus on commercialization and the risk-tolerance inherent to a startup. After all, the underlying concept itself isn’t new — a number of companies have experimented with making acrylonitrile from bio-based glycerol, Tryee told me. “But a lot of these tries happen inside of a large company, which is not as tolerant for risk,” he explained. With Trillium’s investors lined up behind the effort, however, “It doesn’t feel to any one person that if we’re wrong, our whole career is going to go up in flames.”
But there have been technical innovations too. Southern Research had to develop a proprietary catalyst and two-step thermochemical process that converts glycerol into an intermediate molecule and then acrylonitrile. Trillium now has an exclusive license to this process. Once produced, the low-carbon acrylonitrile functions as a simple drop-in replacement for the fossil-based version of the molecule; there's nothing at all different about the downstream supply chain.
Now, the startup is focused on commissioning its newly completed demonstration plant in Texas sometime this quarter, followed by initial shipments soon after. This new capital will also help Trillium conduct the engineering design for its first commercial facility, the potential location of which Tyree would not disclose.
Though glycerol is a relatively cost-effective feedstock, Trillium’s product will still command somewhat of a green-premium, though exactly how much this impacts the final cost of the end product depends on a variety of downstream factors. At the least, Tryee said his company ought to undercut existing green acrylonitrile on the market today, which is produced from low-carbon propylene.
Overall, It’s a promising sign that despite a political environment in which talking about climate is out and affordability is in, a company like Trillium — which depends on customers paying a bit more for a cleaner product — can still raise significant new funding. Political winds aside, Tyree said he’s seen sustained customer interest in cleaning up the chemicals supply chain; there just wasn’t a viable solution for this particular piece of it before now.
“It’s really just been people waiting on somebody to figure out a way to make the product,” he said, referring to low-carbon acrylonitrile“ Now that Trillium has done so, the next question is, who will its initial buyers be, and exactly how much more will they prove willing to pay?
It is a cliché that everyone in the insurance industry believes in climate change. But the same can certainly be said of those in the mountain-guiding business.
May marks the beginning of the recreational mountaineering season on Washington’s Mount Rainier, the most popular technical climb in the country. But for many of the guide companies that take clients up the mountain, the last day of the 2026 commercial climbing season remains an ominous unknown. “We used to run a season through the end of September typically,” Jonathon Spitzer, the director of operations at Alpine Ascents, which has offered guided climbs of Rainier since 2006, told me. “For four of the last five years, we’ve ended around Labor Day or so” due to poor snow conditions on the mountain — meaning a loss of about 20% of the historic season.
In the spring and summer, when the vast majority of Rainier’s 10,000 or so annual climbers attempt to reach the summit, the weather begins to mellow, avalanche danger lessens, and crevasses remain mostly covered. But ideally the mountain should still be frozen hard. A firm snowpack provides crampons and ice axes with the best purchase, allowing climbers to stick to steep slopes without sliding, while reducing the danger of ice and rockslides. Accidents and falls increase when climbing on loose dirt, slush, and rock, as well as when navigating exposed blue glacier ice, which is normally covered in snow and otherwise extremely slick.
Yet high-mountain areas, known as the cryosphere, are warming up to twice as fast as the global average. Rainier has lost half its ice since 1896, with most of that loss occurring in recent years; three of its 29 glaciers have disappeared since 2021. Researchers last fall went as far as to assert that the 14,410-foot mountain is now 10 feet shorter than it was in 1998 due to a rocky outcropping replacing its former highest point, a mound of ice that has since melted away.
For the guides working on Rainier, the weather in April and May sets the stage for the rest of the season, when spring storms ideally dump the snow needed for the summer climbs. “It doesn’t really matter what happens in December, January, February,” Spitzer told me, since winter snow is dry and blows off the summit rather than accumulates. Alpine Ascents had guides on the summit of Rainier last week who reported that the upper mountain has a lot of snow, but Spitzer cautioned that the character of the season ahead is still uncertain. “It’s been really dry in April,” he noted.
And it’s not looking good for May, either. Temperatures in the Puget Sound region are 20 to 25 degrees above average to start the month, a kind of final exclamation point on the wickedly warm winter and ongoing snow drought across the West. The Cascade mountain basins have only around 29% of their historic median snow-water equivalent, the metric used to measure snowpack and provide insight into runoff, water availability, and the fire season ahead. Tom Vogl, the CEO of the Mountaineers, a Seattle-based alpine club that offers local climbing courses, told me that “100%, with almost no uncertainty, we’re going to have a shorter climbing season on Washington peaks this year.”
In Oregon and northern California, where Lassen Peak sits at the southern end of the Cascades’ volcanic backbone, the snow-water equivalent median is as low as 1% in places. “Mount Hood is a mess right now,” Graham Zimmerman, a professional alpinist and the athlete alliance manager at Protect Our Winters, told me.
Zimmerman was on Oregon’s highest peak in February to climb Arachnophobia, a challenging route, and he told me that on “significant sections of the south side of the mountain, up high on the final summit, we were walking on dirt.” Though Zimmerman isn’t a guide himself, many of his friends are, and for “the core season up there in June, it’s going to be pretty intense,” he predicted. “There’s not going to be a lot of ice, it’s going to be pretty dirty, and when those mountains start to thaw out, they get pretty dang crumbly, and that’s going to create a risk for those going up there.”
Think of a mountain like a scoop of Rocky Road in an ice cream cone. Fresh out of the freezer, the scoop holds its shape because everything is frozen in place — but as it starts to melt, marshmallows and nuts begin to slough down the sides.
Except on a mountain, it’s not marshmallows and nuts but avalanches and rockfall. In addition to being a life-or-death hazard in the moment — and top-of-mind for the risk-averse concessioners guiding otherwise oblivious novice clients — the debris on a warming mountain can close routes to the peak, crowding the ones that remain. “When you have a bunch of people on a route, it doesn’t make things safer,” Zimmerman said. “It makes things more dangerous because people knock stuff onto each other, and because it slows things down.”
Even as the season shortens due to inadequate snowpack, more and more people are trying to climb on an ever-smaller number of viable days. That puts additional pressure on the guides, whose clients take time off from work and pay thousands of dollars for the chance to summit within a predetermined window, even as conditions overall become more dangerous.
This strain is particularly visible in the Himalayas, where photos of the conga line headed to the top of Everest go viral every few years. This season, icefall from a glacier closed the route to the world’s highest point for more than a week, with more icefall anticipated, adding to concerns about queues.
Iconic climbs in the Alps are also a mess due to warming weather and snow shortages. Spitzer, of Alpine Ascents, used to guide on Mont Blanc from June through September, but these days, many guides in the Alps stop around July 15 and resume again in mid- to late-August, when the mountains start to firm up again, because the height of summer in Europe is so hot. “The mountains are dynamic right now,” Spitzer said, and “it’s not just here in Washington. We’re seeing it globally.”
This raises, perhaps, the question of “so what?” Mountaineering is a niche, expensive, and often elite pastime. But a low summer snowpack has knock-on effects: “We expect to see pretty significant impacts on [gateway] communities, not just from the perspective of water availability but also how that relates to guiding businesses, water sports, water recreation, and the outdoor industry, which is really big in the West,” Erin Sprague, the CEO of Protect Our Winters, told me. Rafting guides, for example, could also see abbreviated seasons, hurting their bottom line. Outdoor retailers like REI could see sales slump if it’s a particularly bad fire year, keeping people off the trails.
That’s not to mention that 75% of the West gets its water from snowpack, meaning what happens in the mountains will impact even those for whom sweat, bugs, chance bear encounters, and walking uphill for hours sounds like personal torment.
“It’s not just about mountaineers and climbers who experience the glaciers in a more direct way for recreational purposes — it literally touches every person who lives in the Northwest,” Vogl, the Mountaineers CEO, told me. “This should matter.”
It does to me. In 2021, a few weeks after the Pacific Northwest heat dome, I summited Mount Rainier with my dad on the 50th anniversary of his first climb of the mountain when he was 14. In 1971, August 12 had been the peak of the Cascade climbing season; in 2021, we climbed in a haze of wildfire smoke and almost didn’t make it to the summit because of the warm conditions on the mountain. (Vogl, who was leading a trip on the other side of Rainier around the same time, said exposed blue ice and running water were directly responsible for an accident in his group that resulted in a broken femur and required a helicopter evacuation.) Stripped down to my base layers during the descent from the peak, I watched a boulder the size of a minivan come off a rock across the glacier from where we were climbing. In other spots, we had to balance across ladders laid over crevasses so deep you couldn’t see their bottom.
Last fall, I gave birth to my daughter, and I’ve been thinking about what the mountain will look like in August 2071, on the 100th anniversary of her grandfather’s first summit and the 50th of mine. When I asked Vogl what he thought, I expected something optimistic from the CEO of an organization focused on getting people outdoors. But he sounded crestfallen. “Some of the climbs that I’ve done with my kids, I doubt that they’ll be able to do them with their kids because the conditions are going to change so dramatically,” he said.
I also asked Zimmerman, the accomplished alpinist, what he thought about the future of his sport. He meditated on the question throughout our conversation, only to circle back to it at the end. “I don’t think that people are going to stop climbing,” he finally said. “But I think that people are going to need to come to terms with the fact that we’re living in a changing climate.”
“We’re going to have to continue to adapt, to be smart, to really focus on situational awareness while we’re out there,” he went on. The sense of adventure and risk inherent to climbing won’t just be about first ascents and “going to places where people haven’t necessarily been before,” he predicted — because “even the places we have been are changing.”
