Plus cheese and eggs, if you want to go all the way.

It was burrito night — I had some tortillas, salsa, guacamole and red onion in my refrigerator, but all our meat was still frozen, and I didn’t have any beans handy. So I did what any climate reporter with an interest in food systems would do and grabbed a pack of meatless “carne asada” I’d picked up out of curiosity and threw it into the mix. The end result was more “huh” than “wow,” but it held its own — with a little help from some hot sauce.
Growing, raising, processing and transporting food is responsible for roughly a quarter of worldwide greenhouse gas emissions, nearly 60% of which comes from meat production, according to one estimation. If you're concerned about your personal carbon impact, eating less meat is probably on your to-do list. But what if you still like a carne asada burrito? Thankfully, there are plenty of companies working on satisfying your cravings, no animals involved.
There are lots of other food system concerns that won’t make it into this guide — things like agricultural livelihoods, water use, and animal well-being. But if you’re curious about how fake meats work, what they taste like, and their emissions impact, here’s what you’ll want to know.
Ben Kelley, owner and proprietor of Kelley Farms Kitchen, a vegan restaurant in Harpers Ferry, WV. Ben and his wife Sondra started Kelley Farms after going vegan themselves more than a decade ago. The cafe offers a mix of housemade and commercially available meat alternatives.
Ismael Montanez, the program manager at University of California Berkeley’s Alt Meat Lab, where he’s focused on food and sustainability broadly. He is co-founder and former CTO of plant-based lamb company Black Sheep Foods and eats both meat and plant-based replacements.
Andrea Cecchin, senior agriculture and carbon researcher at HowGood, a sustainability ratings company. Cecchin told me he and his family limit the amount of meat they eat but are focused on a wider plant based diet.
It’s a multi-trillion dollar question, frankly. While the worldwide food system is far more complex than individual consumer choices, shifts in demand for food products, especially among higher-income individuals, have created changes, such tripling the price of quinoa during a boom in its popularity in mid-2010s. The U.S. and China’s growing middle classes also drove a spike in pork demand, only to have that growth slow and reverse in the past few years over health concerns.
The plant-based meat alternatives currently available at your grocery store may be highly processed, but they’re different from the cultivated or “lab-grown” meat coming from a new batch of food companies that seek to “grow” meat from scratch on the cellular level. In theory, this would create direct replacements for things like steaks or fish without actually requiring us to raise actual animals. Almost all of these products are still in the research and development stage, however, and none are currently commercially available in the U.S.
Let’s not mince words: There is no such thing as carbon-neutral beef. How to reduce cattle’s climate impact is an area of active research, encompassing supplements and dietary changes, breeding programs to create animals that process food more efficiently, and even methane-sucking gas masks. There are also ranchers committed to using specific grazing techniques that encourage extra retention of soil carbon, thereby offsetting emissions from cows, but “the science is not there yet” on the scale of sequestration needed for fully carbon-neutral meat, Cecchin says. “Climate-friendly” or “low-carbon” meat labels have been criticized for a lack of data transparency and only represent a 10% reduction in beef emissions overall.
The process of making plant-based mock meats is basically the reverse of their animal version, Montanez explained. While meat is made by processing animals into specific cuts or parts, plant-based replacements use protein-packed flours and other ingredients to build the “meat” back up.
Almost all fake red meat products will have a smaller greenhouse gas impact than their animal versions, Cecchin explained. Compared to a beef burger, the alternatives “really bring down the carbon footprint — the amount of water we need to use, and the amount of land that we use” per unit of food. But for other products, the savings are less clear. Chicken, for instance, has a much lower footprint, meaning replacements have to compete against a “very efficient industry and a very efficient meat.”
Processing details are rarely public, making it difficult to declare other meat replacements automatic emissions winners. “It’s really company by company, and could even be year by year as processing efficiencies change,” Cecchin said, adding that he hopes more companies will show clear evidence of their total emissions, including being specific about what they are comparing against.
Fake animal products are also not the same nutritionally as actual animal products, in ways that can be positive or negative depending on your specific dietary needs. An allergy to soy or wheat gluten would immediately knock out a good portion of these options, and my carne asada came with a warning to anyone “sensitive” to fungi.
There are generally more carbs, less fat, and more fiber in substitutes compared to meat, but protein levels can vary widely, and sodium levels can be high (e.g. Impossible burgers have just as much fat and more salt than a 80% lean beef burger of the same size, though zero cholesterol). As with any processed or prepared food, a look at the nutritional label is well worth it.
The experts all enjoyed the big-name beef replacements — Cecchin even said he has chosen Impossible and Beyond patties over regular burgers while eating out. If you have a little more time, though, Kelley said to skip the fast food fake burgers and make them yourself. Making good tasting meat replacements isn’t all that different from cooking meat itself: spices, technique and how it integrates into a meal makes all the difference. This is the case whether he’s using Impossible beef on the restaurant griddle or hand-making a black bean and chickpea patty. “Just like a raw piece of chicken,” he said, “it's about how you cook it.”
Everyone I spoke to said most breaded chicken replacements match their animal versions pretty well — Montanez even called them “most consistently tasty” than their actual meat equivalents, which for him was enough to justify the slight additional cost. He said he thinks Impossible’s chicken nuggets are the “most convincing” — although he also cautioned that he doesn’t eat a lot of breaded meat products in the first place.
Morningstar Farms’ Chik Patty has been a go-to at-home lunch in my house for nearly three decades, primarily because of that consistency and ease of preparation. (The “buffalo” flavor is by far the best, in my opinion.) Kelley uses Gardein’s Chick’n on one of their most popular sandwiches at the restaurant — they’re a big fan of the company and product.
Don’t expect a lot of options for raw chicken alternatives, however. Montanez suspects the economics of competing with relatively cheap meat isn’t attractive to companies, especially when prepared breaded versions, both animal and plant-based, are already popular.
“Emulating the flavor of American chicken is relatively easy and shouldn't be seen as a significant achievement,” Montanez said. “What’s truly interesting is creating a versatile analog that can withstand the same cooking conditions as real chicken.”
Kelley’s favorite meat replacement is Beyond’s bratwurst sausage, made with pea protein and avocado oil. He uses it in a variety of meals at his cafe, as well as to grill up at home, sometimes adding it to pasta.
Steak and other meats that include marbled fats have been a particularly tricky nut to crack for fake meat producers because the traditional extrusion process makes it difficult to capture fat alongside protein. Montanez told me Juicy Marbles has developed a process capable of doing both, which it’s used to create filet and loin products.
Montanez’s favorite fake bacon is only available in a vegan deli in Berkeley, California, but generally both he and Kelley haven’t found full bacon strips that really match the experience of eating bacon. “There's no way to hold it after you cook it without it drying out,” Kelley said. Instead, he likes using soy [bacon] crumbles in various dishes, including in his potato salad.
The pepperoni and other fermented charcuterie from Prime Roots is “quite impressive, even from a meat eater’s perspective,” Montanez told me. The company starts its process with koji, a strain of fungus that has been part of Japanese cuisine for hundreds of years, including in the product of soy sauces and sake.
The deli slices Kelley uses in sandwiches like reubens or Italian hoagies are made with seitan or a mix of seitan and soy, from a variety of companies. But the Tofurky brand (not just turkey) is one of their favorites. “We are always testing new recipes of our own and using reliable and ethical companies that we grew up loving,” he said.
Kelley has yet to be convinced by most seafood replacements, he told me. “All the seafood is kind of just the same as the chicken replacements,” he said. Instead, he uses unripe jackfruit – a common meat replacement with a stringy texture – hearts of palm, and spices to replicate crab cakes. Having an exact match isn’t always a priority for Kelley, who’d rather highlight an ingredient that serves as a replacement rather than calling it by its faux name. His lobster roll replacement is made with hearts of palm, but it’s not “vegan lobster” on his menu, it’s a “hearts of palm” roll.
Texture is a “very difficult thing in seafood,” Montanez said. “I haven't seen anything myself where it is 100% convincing,” but he points out companies like Impact Food that are making plant-based sushi without extrusion or fermentation, currently available in some New York and California restaurants.
Montanez also called out vegan cheese as a category that struggles to match its original, citing texture, not flavor, as the sticking point, especially when it needs to work in a multitude of different recipes. “You might see a vegan cheese that’s okay applied in pieces,” he said, “but it's only as good if you put it in pizza oven temperatures.” An exception to the rule for him is Climax Foods’ blue cheese, which almost pulled off a Judgment of Paris-like upset in a food competition this year before being removed from the running.
Montanez identified Quorn as a brand that’s not trying to replicate meat exactly, but tastes good on its own. The British company has a wide range of no-meat products that feel like they could have a home in a Tesco, from a vegan Yorkshire ham to mini sausage rolls to “picnic eggs.”
Approaches to fake meat taste fall on a spectrum. On one end are companies that try to replicate as closely as possible the taste, texture, and smell of some specific meat product — say, a chicken nugget. (Your personal mileage may vary when it comes to replicas of more complicated meat cuts such as steaks or pork chops.) On the other end are brands that offer a functional, hopefully flavorful replacement for meat in a meal but otherwise aren’t trying to fool anyone.
The former approach involves more materials science and chemistry, Montanez told me. For example, Impossible makes a soy version of a key molecule in meat known as heme and combines it with a carefully calibrated proportion of sugars, fats, and water to induce the Maillard reaction, the process that makes meat brown and form a crust. It’s possible to create a similar meaty flavor profile without heme (Impossible has a patent on their version), but they have their own complications.
“It’s those sugars reacting with the proteins and creating these molecules that ultimately result in a meaty aroma or flavor,” Montanez said.
Kelley Farm’s menu is a good example of the wider ingredient possibilities of meat replacements beyond this approach. In addition to Impossible patties, Beyond brats, and Gardein’s Chick’n, the restaurant also serves deli meat replacements made with seitan (basically textured wheat gluten); folded eggs made from mung beans; BBQ pulled pork made from jackfruit, which mimics that stringy texture naturally (I’ve had both Kelley Farms’ barbeque sandwich and commercial jackfruit BBQ versions and would happily eat either again); and a burger patty that’s their own mix of chickpeas and black beans.
It’s also worth noting that there is a more literal approach to eating a plant-based diet that’s already the standard in many other countries — that is, rather than replacing meat products with fake meat products, just eat more plants. If you feel like you’re missing out on protein, beans, lentils, tofu, and certain grains like quinoa, farro or teff, have high amounts.
Highly engineered meat substitutes are often more expensive than the animal products they are replacing, so if you’re struggling with hunger, have specific dietary requirements, anxiety around food, or an eating disorder, concerns about emissions shouldn’t even enter the picture.
For that matter, just reorienting your approach to eating meat saves a lot of carbon on its own. Kelley told me he reaches for meat replacements when he’s craving something specific, while Cecchin prefers meat alternatives when he’s eating out.

On Trump’s dubious offshore wind deal, fast tracks, and missed deadlines
Current conditions: At least eight tornadoes touched down Wednesday between central Iowa and southern Wisconsin, and more storms are on the way • Temperatures in Central Park, where your humble correspondent sweltered in a suit jacket yesterday afternoon, hit 90 degrees Fahrenheit, shattering the previous record of 87 degrees • Mount Kanloan, a volcano on the Philippines’ Negros island, is showing signs of looming eruption with dozens of ash emissions.
The Trump administration appears to be tapping an essentially bottomless but highly restricted pool of federal money at the Department of Justice to pay the French energy giant TotalEnergies the $1 billion the Department of the Interior promised in exchange for abandoning two offshore wind projects. Heatmap’s Emily Pontecorvo got her hands on a document that suggests the fund, which is typically reserved for helping federal agencies pay out legal settlements, may have been improperly used for the deal. Tony Irish, a former solicitor in the Department of the Interior who unearthed a letter in the public docket from his former agency to TotalEnergies and shared the document with Emily, told her that the terms of the French energy giant’s lease are such that a lawsuit requiring monetary damages couldn't have been reasonably imminent. Without that, there would be no credible reason to dip into the Judgment Fund for the payout.
This morning, Emily published another banger. While listening to Secretary of Energy Chris Wright speak before the House Appropriations Committee Wednesday, she noticed the cabinet chief say that “well over 80%” of the 2,270 awards reviewed by agency were now moving forward. But there are “big holes” in that number, which doesn't account for several grants to blue states that a judge mandated be reinstated, or for energy efficiency rebates that are still in limbo.
Louisiana’s Public Service Commission voted 4-1 to fast-track a proposal from Facebook-owner Meta and the utility Entergy to build seven new gas-fired power plants, in a $16 billion investment into fossil fuel infrastructure. The project is, according to the watchdog group Alliance for Affordable Energy, one of the largest single power requests in state history. The timeline established under the vote today requires a final vote on the application by December.
The federal government, meanwhile, is getting interested in how much power data centers use. The Energy Information Administration is planning to implement a mandatory nationwide survey of data centers focused on their energy use, Wired reported, calling the move the first such effort to collect basic data on the server farms’ power demands.

Super Typhoon Sinlaku slammed into the Northern Mariana Islands as the most powerful storm on Earth so far this year, plunging the U.S. territory into darkness. It’s unclear just how many of the remote Pacific archipelago’s 45,000 residents lost grid connections amid the storm. But reports indicate island-wide blackouts. Local officials told the Associated Press it could take weeks to restore power and water service across the territory. Even if cellphones were charged, Pacific Daily News reported that wireless networks were overloaded and slow throughout the storm. Saipan, the capital, and neighboring Tinian were plunged into “total darkness,” according to Pacific Island Times.
The incident highlights the particular risk that the five populated U.S. territories face from extreme weather. All five — Puerto Rico and the U.S. Virgin Islands in the Caribbean; Guam, the Northern Mariana Islands, and American Samoa in the Pacific — are island chains vulnerable to hurricanes, typhoons, and rising seas. And all five depend on increasingly costly imports of oil and gas to generate electricity. This September will mark nine years since Hurricane Maria laid waste to Puerto Rico’s aging grid system.

Over at NOTUS, reporter Anna Kramer found that the Interior Department “has blown past a congressionally-mandated deadline to report its progress on energy projects.” Per a letter from Senate Democrats, the agency failed to submit two required reports to Congress on its reviews and approvals of energy projects, which wind and solar developers say reflects the administration’s ongoing de facto embargo on permits for renewables.
Overall, 2025 was a worse year for zero-emissions trucks than 2024. Annual total registrations of medium- and heavy-duty vehicles that don’t run on gasoline or diesel fell by 7.6%, according to new data from the International Council on Clean Transportation. But the decline wasn’t uniform across all segments: The medium-duty truck, such as a box truck or a delivery truck, saw a 61.7% surge in zero-emission vehicle registrations year over year. That held even as buses fell 32.8% and heavy-duty trucks, such as flatbeds and dump trucks, declined 20.7%.
The times, they are a-changing over at the Natural Resources Defense Council. Once a stalwart opponent of nuclear power and supporter of stricter and more onerous environmental rules, the conservation-focused litigation nonprofit first embraced the need to restart existing nuclear plants, in a major shift. Now the NRDC has thrown its weight behind permitting reform, calling on lawmakers to speed up the process for approving clean energy projects. Green groups like NRDC once derided an overhaul of the landmark U.S. environmental laws as a deregulatory assault on nature. What’s going on here? The Foundation for American Innovation’s Thomas Hochman put it simply: “Vibe shift.”
The Secretary of Energy told Congress that his agency had completed its review of Biden-era funding commitments.
Secretary of Energy Chris Wright testified in front of the House Appropriations Committee on Wednesday to defend his agency’s proposed 2027 budget. Under questioning from Democrats, Wright told the committee that his department’s review of Biden-era funding, announced in May 2025, had “finally come to a completion.”
“Well over 80%” of the 2,270 awards reviewed were moving forward, he said. Some would proceed as originally conceived, while others would be modified. “We have finished that effort, and we are keen to move forward with the majority of the projects which did pass, either straight up or through restructuring,” he testified.
But that assertion obscures the level of uncertainty that remains about the funding.
To back up his statement, Wright sent Congress a list of grants titled “Retain/modify,” which named roughly 1,950 awards — a number consistent with his “well over 80%” of 2,270 number.
But there are big holes in the data. As one example, in January, a federal judge ruled that DOE had to reinstate seven awards the agency terminated last year, ruling that the agency’s targeting of awards in blue states violated Constitutional protections against discrimination. But just one of those seven awards — which should all theoretically be “retained” — is on the list sent to Congress this week. (The single retained award is a nearly $20 million grant for Colorado State University’s Methane Emissions Technology Evaluation Center.)
Meanwhile, 18 other awards that were terminated as part of that same targeting on blue states, but which were not named in the court case, are on the new list. In other words, 18 awards that had been publicly deemed “terminated” and were not reinstated by a judge have been cleared to progress.
Wright’s stats are also misleading in that the new list doesn’t include any of the funding the DOE is statutorily required to pay out to states based on pre-set formulas, such as funding for long-established Weatherization Assistance Programs or the home energy retrofit programs created by the Inflation Reduction Act, which also fell victim to the agency’s review. As I reported last summer, many states were stuck in a holding pattern waiting for the DOE to respond to their applications for the IRA rebate funding.
During the hearing, Representative Debbie Wasserman Schultz of Florida asserted that the agency was still withholding more than $345 million in funds for her state’s energy efficiency rebate programs. Representative Rosa DeLauro of Connecticut raised the same issue.
Wright told DeLauro that the timing for releasing the funds was “in the near future,” and could be as soon as a few weeks away. Later, when Wasserman Schultz pressed him again, Wright said he didn’t know when the funds would be released.
“I do not have a specific answer to that at the tip of my tongue,” Wright said. “I know a lot of these broad scale rebate programs, we’ve gone through to look at carefully, to make sure we get rid of fraud on these things …”
“$345 million is a lot of damn money,” Wasserman Schultz said, cutting him off. “And $8,000 to $14,000 grants are the kinds of things that help struggling homeowners dealing with high electric bills to try to reduce those costs. I would think that you would know at least something about what I’m talking about when you are withholding that much money.”
In response, Wright argued that there was “an incredible amount of fraud” in the programs and “DEI stuff put in,” referring to diversity, equity, and inclusion programs, against which the Trump administration has mounted a crusade. The rebate programs were specifically designed by Congress, in statute, to help lower- and moderate-income households afford home upgrades like heat pumps.
Wright did not provide any information to Congress about which projects were being “modified” versus approved as-is, or describe how the “modified” projects were changing course. He did, however, indicate that the agency was still open to reconsiderating grants that had been terminated. During the hearing, Representative Mike Levin of California brought up his state’s canceled ARCHES hydrogen hub, which had been eligible for up to $1.2 billion in DOE funding. He asked whether Wright would “commit to engage in good faith” with the hub’s leadership, who “want to work collaboratively with you.”
“Absolutely,” Wright replied. He said that the ARCHES hub failed to prove it had a viable pathway to meet its cost goals, but that he was “absolutely open for that dialogue.”
Rob follows up on his scoop with Jack Andreasen Cavanaugh of Columbia University’s Center on Global Energy Policy.
For the past few years, Microsoft has basically carried the carbon removal industry on its shoulders. The software company has purchased 72 million tons of carbon removal, more than 40 times what any other organization has financed, according to third-party sources.
Now it’s pulling back. As we reported last week, Microsoft has told suppliers and partners that it’s pausing new purchases. Though the company says that its program “has not ended,” even a temporary pullback will have significant implications for the nascent carbon removal industry. What happens next for these companies? And is a bloodbath on the way? On this week’s episode of Shift Key, Rob speaks to Jack Andreasen Cavanaugh from Columbia University’s Center on Global Energy Policy about Microsoft’s singular importance and what could come next.

Here is an excerpt from their conversation:
Jack Andreasen Cavanaugh: To your original question about where to go forward from now, you could have another surplus of what you just described come up — climate commitments could kick back up again, and we would just do this whole thing over again. We would run it back, and we would be having this conversation, you know, five years from now, or whenever that is. And the way to hedge against that from happening — and to some extent stop it from happening — is to have federal governments across the globe pass durable policy that either compels the regulation or incentivizes the deployment of carbon dioxide removal. And that ... because carbon dioxide removal — outside of the co-benefits of some pathways, which are fantastic, just removing carbon from the atmosphere for pure carbon’s sake is the tragedy of the commons in a single climate technology entity. Like, this is something that will need federal support in the long run, to some extent, in a way that other climate technologies don’t. That’s true of most of the carbon management world, but it is uniquely true of CDR.
Robinson Meyer: But it’s a form of waste management. Trash and recycling also require ongoing government support. Now, at this point, it tends to come from the state and local level. But governments still pay to handle waste. That’s part of what we expect governments to do. It’s just that this waste happens to be in the atmosphere and requires a particularly high form of technology to dispel.
Cavanaugh: Yeah, it’s a very costly trash pickup service. And it also is contingent upon people caring about the trash. There is a relatively large constituency around the world that is unconvinced that the trash is an issue. And that is the big challenge.
