The biggest climate decision at your next cookout is not the grill you buy. It is what you put on the grates. A backyard charcoal barbecue for four people can release as much greenhouse gas as an 80-mile car drive; and most of that comes from the meat, not the fuel, according to researchers at the University of Sheffield’s Institute for Sustainable Food.
Grilling season is back, and a new grill is a chance to cut the emissions from summer entertaining. But the fuels are only part of the story, and the rankings have shifted since this guide first ran. The U.S. power grid has gotten markedly cleaner, which changes the case for electric grills. Before you head to the store, it helps to understand the carbon impact of charcoal, wood pellets, propane, natural gas, electricity, and solar — and where each one actually lands. And if you’re replacing an old grill, don’t forget to recycle the one you’re retiring.
Start With What’s on the Grates
Cook from scratch and you’re already ahead. Preparing a meal from whole ingredients rather than processed food can lower its global warming and human toxicity potential by up to 35%, according to a study in the Journal of Cleaner Production. That doesn’t make a barbecue carbon-free, though — and the single largest lever you control is protein.
The Sheffield team compared three grilled meals and found the gap is dramatic. A beef-heavy cookout was the most carbon-intensive option they measured, while swapping beef burgers for chicken cut the barbecue’s emissions by roughly a third, and a fully plant-based spread cut them by more than half. The lifecycle impact of the food, especially red meat, typically dwarfs the footprint of the fuel used to cook it. A burger’s beef carries far more embodied carbon than the propane needed to char it.
Put plainly: grilling more vegetables, chicken, or plant-based options is the highest-impact change most people can make at a cookout. The fuel decisions below matter — they’re just the second-biggest lever, not the first.
The Burning Truth About Fuels
Grilling is a science, as any grill master knows. A meal for four takes roughly 30 minutes to an hour on the grates, and different fuels need different lengths of time to reach cooking temperature. The estimates below assume about one hour of cooking to make dinner for four — your actual results will vary with the grill and fuel you use.
Charcoal: The Most Polluting Choice
Dinner for four needs about 300 square inches of grill space for meat, vegetables, and warming buns. Charcoal runs about 30 briquettes per 100 square inches, so you’ll need roughly 90 pieces. At an average briquette weight of about 0.8 ounces, that’s about 4.7 pounds of charcoal for the meal.
Charcoal carries two carbon costs: the embodied carbon of making the briquettes and the emissions from burning them. Manufacturing is the hidden problem. Charcoal is produced by heating wood in a low-oxygen kiln until moisture and volatile compounds cook off, leaving nearly pure carbon, and only about 20% to 35% of the original wood’s energy survives the process. The rest burns off during production. Estimates put the manufacturing footprint at roughly 3.5 to 7 pounds of CO2 per pound of charcoal, before you ever light the grill.
Burning the 90 briquettes for an hour adds about 21 pounds of CO2, plus roughly 0.79 pounds of carbon monoxide and 1.6 pounds of particulate matter. All told, a single charcoal cookout for four exceeds 28 pounds of CO2 along with other pollutants and is by far the most polluting way to grill. Eric Johnson’s lifecycle comparison in Environmental Impact Assessment Review reached a similar verdict: charcoal’s carbon footprint is roughly three times that of liquefied petroleum gas.
There’s a footprint upstream of your patio, too. Worldwide, woodfuel harvest, which includes wood used to make charcoal, accounts for about 30% of the estimated 2.1 billion tons of CO2 released annually by forest degradation across developing countries, according to research published in Carbon Balance and Management. In parts of Africa, charcoal production now rivals outright deforestation as a driver of forest loss. The wood in a U.S. bag of briquettes may be sourced differently, but the global picture is a reminder that “natural” charcoal is not the same as low-impact.
Wood Pellets: Second Place, by a Wide Margin
Wood pellets are a popular charcoal alternative, and some grillers treat them as a low-carbon, renewable fuel. Cooking on a 300-square-inch grill takes about two pounds of pellets.
Embodied carbon varies widely with the wood used, the manufacturing process, and how far the pellets travel. In general, a pound of pellets carries about 0.09 pounds of embodied carbon and produces about 1.8 pounds of CO2 when burned — putting our four-person dinner at roughly 3.78 pounds total. Because pellets burn cleaner than charcoal, the meal generates only a few grams of carbon monoxide, particulate matter, and nitrogen and sulfur compounds. Pellets are the second-worst option on this list, but at a fraction of charcoal’s impact.
The Lower Footprint of Cooking With Gas
Propane and natural gas grills carry a lower environmental impact than charcoal and pellets, mostly because they heat fast and switch off the moment you’re done. That control over cooking time makes a real difference — charcoal keeps throwing off heat and emissions long before the grates are ready and well after the food comes off. Gas also keeps far more of its energy: propane retains roughly 90% of its energy from wellhead to grill, against charcoal’s 20% to 35%.
A propane grill uses about a half pound of propane for the 30 minutes our four-person meal needs. Including the embodied carbon of producing and delivering the fuel, that session totals about 1.99 pounds of CO2.
Natural gas usually requires a gas line plumbed to the home, so propane is more convenient for many grillers. A 30-minute cook uses roughly 1.2 pounds of natural gas, for a footprint of about 1.73 pounds of CO2. One caveat worth naming: natural gas systems can leak methane, a greenhouse gas far more potent than CO2 over the short term, which the combustion math above doesn’t capture.
Electric Grilling Has Quietly Become a Top Choice
For years the conventional wisdom held that electric grills were the dirtiest option, citing a 2003 Oak Ridge National Laboratory analysis from an era when coal dominated the power grid. That conclusion no longer holds, because the grid underneath it has changed.
In 2023, generating a kilowatt-hour of U.S. electricity produced about 0.81 pounds of CO2 on average, according to the U.S. Energy Information Administration — down sharply from the coal-heavy mix of two decades ago, and still falling. The EPA’s emissions database shows grid carbon intensity dropping again by an average of about 3% from 2023 to 2024 as wind, solar, and natural gas displace coal.
Run the math on a modern electric grill, which draws roughly 1.5 to 1.8 kilowatts, and an hour of cooking on the average U.S. grid now produces somewhere in the neighborhood of 1.2 to 1.5 pounds of CO2. That puts it below propane on the typical grid — and well below charcoal — with one feature no fuel-burning grill offers: it gets cleaner every year on its own, as the grid decarbonizes, the same logic that drives heat pumps and electric vehicles. If your power comes from a cleaner-than-average source — rooftop solar, a green-power plan, or a state rich in hydro, wind, or nuclear — the number drops further still. Pair an electric grill with a solar generator and you approach a genuinely zero-carbon cookout.
The honest tradeoff is flavor and feel. Electric grills heat with coils or elements rather than open flame, so they don’t impart the same smoke, and purists notice. Cast-iron grates can deliver sear marks, and add-on smoking accessories help, but this is the option where the cooking experience differs most from a traditional grill.
Solar Cooking: Zero Fuel, Real Limits
Solar ovens use reflectors to concentrate sunlight on a sealed cooking chamber, making a meal with no fuel and no direct emissions. They excel at slow, moist, flavorful cooking — think baking and braising more than searing.
The limits are practical. It takes a genuinely sunny day to reach broiling or grilling temperatures, output drops with the light, and solar cookers don’t produce the signature grill lines many cooks prize. As a complement to another method — or for the right dish on the right afternoon — solar is unbeatable on carbon. As an everyday grill replacement for most households, it’s a harder sell than a clean-grid electric model.
The Carbon Impact of Grilling
A season of cooking 45 meals using each of the options we’ve reviewed will produce the following emissions:
- Charcoal: 1,260 lbs. of CO2, plus other pollutants
- Wood Pellets: 170 lbs. of CO2, plus some other pollutants
- Propane: 90 lbs. of CO2
- Natural Gas: 78 lbs. of CO2
- Solar: No CO2
Stretch these single-meal figures across a season of 45 cookouts and the differing environmental become starkly evident. The table below assumes the same four-person meal each time, cooked on the average U.S. grid for the electric estimate.
| The Carbon Cost of Grilling, by Fuel | ||
| Fuel | Per Meal (4 people) | 45-Meal Season |
|---|---|---|
| Charcoal | 28+ lbs. CO2, plus pollutants | ~1,260 lbs. CO2, plus pollutants |
| Wood pellets | ~3.78 lbs. CO2 | ~170 lbs. CO2 |
| Propane | ~1.99 lbs. CO2 | ~90 lbs. CO2 |
| Natural gas | ~1.73 lbs. CO2 | ~78 lbs. CO2 |
| Electric (avg. U.S. grid) | ~1.2–1.5 lbs. CO2, falling yearly | ~55–65 lbs. CO2, falling yearly |
| Electric (clean power) / Solar | Near zero | Near zero |
| Charcoal, gas, and electric are not roughly equivalent; they’re separated by a factor of three or more. Electric figures assume the average U.S. grid (~0.81 lb CO2/kWh, 2023) and drop further on cleaner power. Sources: U.S. EIA; EPA eGRID; University of Sheffield Institute for Sustainable Food. | ||
What You Can Do
If you’re buying a new grill
- Consider electric first. On today’s grid it beats propane, and it keeps improving as power generation cleans up, with no equipment swap required.
- If you want flame, choose gas over charcoal. Propane and natural gas heat fast and shut off instantly, cutting both fuel use and emissions.
- Recycle the grill you’re replacing rather than sending it to landfill. Check Earth911’s recycling locator for locations near you that accept grills, metal, or appliances.
If you’re keeping the grill you have
- Cook with the lid down to trap heat and burn less fuel per meal.
- Preheat for about 10 minutes instead of 20, and turn a gas grill off the moment the food is done.
- If you grill on charcoal, skip lighter fluid and use a chimney starter — a metal cylinder lit with a sheet of newspaper, usually under $20. Choose lump charcoal over briquettes, ideally from a brand that names its wood source, and light only as much as you need.
The change that beats all of the above
- Grill more vegetables, chicken, and plant-based options. Shifting even a few beef meals to chicken or veggies each season cuts more emissions than switching fuels does. The food is the bigger lever.
- Cook from scratch with whole ingredients to trim the lifecycle footprint of the meal itself.
The grilling choices you make this summer carry a long-term climate cost, or savings. Pick the cleaner fuel where you can, rethink what goes on the grates, and the backyard barbecue stays exactly as good while asking a lot less of the planet.

Last winter, we kept our house at 60 degrees and our electric bill was STILL $280. I’ve been interested in solar for a long time, but on the long list of house projects (especially when you’re restoring a 200 year old house on the historic registry) some are more pressing than others.
But with a few of those major projects wrapping up, and a daunting bill before me, I figured now was the time for a quick google search on solar panels, and let me tell you….. It can be very overwhelming.
Figuring out the rules (cough, cough, historic society), incentives or rebates if applicable, how much it would cost, how much we could save, etc. felt a little like a part-time job. But, one website made it really easy to compare things, and I am happy to be partnering with Aurora Solar to share that site with you.
Because I think you should be able to easily run the numbers on your house without a lot of hassle!
This post is sponsored by Aurora Solar, but all thoughts and opinions are my own.
If you’ve ever gotten a solar quote, there’s a good chance that Aurora Solar was involved. Aurora was founded in 2013 after its co-founders spent seven months trying to design a solar energy system using a patchwork of different tools.
Afterall, designing a solar system shouldn’t be harder than actually installing one. So they built software specifically for solar professionals. Today, more than 7,000 solar organizations use Aurora, and more than 20 million solar projects have been designed using the platform. They are also the largest solar software provider in the world. Their software is used by roughly 80% of the top 75 residential solar companies in the U.S.
All of this tech has been primarily used by professional installers to map your roof and then create a proposal, but now Aurora is offering this tech to us to help compare quotes.
So instead of having to call a bunch of different installers, I could use the Aurora Solar Marketplace to understand my solar potential, compare estimates, understand my possible savings, look into battery storage and other home electrification incentives, and map out different financing options.
1. know how much electricity the system will actually produce
Before you even get into the price, make sure you understand what you’re actually being quoted.
Two solar systems can have very different prices because they may not be the same size or produce the same amount of electricity. A cheaper system might simply have fewer panels and offset less of your electric bill.
With Aurora, you can compare solar estimates and see the system size, energy production, and how much electricity the system should offset.
You can also upload your utility bill to get a solar estimate based more closely on your actual energy usage, to make the quote accurate for you instead of a ‘generic household’.
2. understand the solar payback period
Aurora calculates things like payback period and lifetime savings, which makes it much easier to understand the long-term finances.
The solar payback period is basically how long it takes for your estimated savings to make up for what you spent on the system, and this is the number that surprised me most!
One estimate had a payback period of around 7 years, and another was closer to 11 years! Over 25 years, two of the estimates I looked at had almost a $13,000 difference in projected savings.
Of course, these are still projections as electricity rates can change (HELLO 2026) but when you’re trying to compare two options for the same house, knowing that one is projected to pay for itself four years sooner is pretty useful information.
3. look beyond the monthly payment
Depending on the installer, you may be looking at a cash purchase, solar loan, lease, or power purchase agreement.
But thankfully with Aurora you can compare the different financing options side-by-side which makes it a lot easier to see the trade-offs. One option may have a lower upfront cost, another may have a lower monthly payment, and another may give you better long-term savings.
4. find out which solar incentives actually apply to you
The minute you start Googling solar, you can find federal incentives, state incentives, utility programs, rebates, net metering, and a whole bunch of information that may or may not even apply to where you live.
And some of the articles ranking at the top of Google are several years old! (RIP to the federal incentives canceled at the end of 2025.) But, Aurora can account for solar incentives when calculating the cost and savings of a system, including state, local, and utility-specific programs.
I would still double check any incentive or tax benefit you’re planning to use before signing a contract, especially because programs and eligibility can change, but having all the relevant information in the same place makes the research process much less overwhelming.
5. research the installer, equipment, and warranties
Aurora lets you compare solar installers based on things like reviews, reputation, pricing, and financing options, which I think is just as important as the actual quote.
I’d also look closely at what equipment is included. What panels are they using? What kind of inverter? How long are the equipment warranties? Is there also a workmanship warranty from the installer? Who handles repairs if something goes wrong five or ten years from now?
And, I know I’ve said it a million times, but it’s nice to see it side-by-side without having to fill out a bunch of forms and be hounded on the phone just to get an idea of what solar may look like.

Sustainability In Your Ear: XPRIZE’s David Babson on Why Climate Grand Challenges Need Buyers, Too
Buyers contracted nearly 30 million tons of durable carbon removal in 2025, more than triple the 2024 total, according to CDR.fyi data reported by Heatmap. About 90% of those purchases came from a single company, Microsoft, and suppliers delivered only about 450,000 tons during the year. That is a sliver of the six to 10 billion tons of removal a year that climate scenarios suggest the world will need by 2050. The technology to pull carbon out of the air works, but the customers needed to scale it remain scarce.
Our guest today, David Babson, is executive vice president of the Energy, Climate, and Nature domain at the XPRIZE Foundation. He calls the slow progress a market failure, because the technology is progressing faster than it is being adopted. Babson previously led MIT’s Climate Grand Challenges initiative and was a program director at the U.S. Department of Energy’s ARPA-E. His portfolio includes XPRIZE Carbon Removal, which drew 1,334 teams and whose participants have raised more than $3.3 billion. In April 2025, Mati Carbon won its $50 million grand prize for spreading crushed basalt on smallholder farms in India, where the rock locks away carbon dioxide. “If people could make money taking carbon out of the air and putting it underground, as opposed to only being able to make money taking it from underground and putting it in the air, we would be in a better place,” Babson says. Mati is weathering the slump in part because its rock dust also improves soil health and crop yields, giving farmers a reason to participate that doesn’t depend on carbon credit prices.
XPRIZE’s answer is to change what winners receive. Babson describes “mixed purses” that pair a cash award with a guaranteed buyer through an advance market commitment, a power purchase agreement, or an offtake contract. In one thought experiment, a carbon removal prize would come with a separate $1 billion fund raised from credit buyers, which qualified teams could draw on as they deliver verified tons. XPRIZE is applying the same thinking to a planned series of fusion energy prizes, pairing technical milestones with market mechanisms to build the supply chain that commercial fusion will require. The same gap between invention and adoption shows up in other XPRIZE competitions. On September 23, XPRIZE Wildfire awarded about $4.55 million from its $11 million purse, with defense contractor Anduril Industries taking first place in autonomous fire response along with a $1 million Lockheed Martin bonus. Babson expects costs to fall as fire agencies adopt the tools and as startups license individual components into cheaper platforms, though underfunded agencies will need a way to buy the first systems. He also notes that the competition left fuel management and ground-based autonomy for future prizes. Earlier this year, program director Andrea Santy told us that field testing had moved ahead of drone regulations. In biodiversity, Limelight Rainforest won $5 million for surveying 100 hectares of tropical forest in under 24 hours and identifying more than 250 species. Biodiversity still lacks a price, but Babson argues that once ecosystems can be measured, slow-walking policy becomes “a dereliction of what they should be doing.”
We also discuss the tension inside XPRIZE’s vision of “equitable abundance,” including a $101 million Healthspan prize that could add years of consumption to longer lives. Babson argues that abundant, cheap clean energy would let society move beyond efficiency as its organizing principle, powering uses such as indoor vertical farms that could return millions of acres of farmland to nature.

Interview Transcript
Mitch Ratcliffe 00:36
Hello. Good morning, good afternoon, or good evening, wherever you are on this beautiful planet of ours. Welcome to Sustainability In Your Ear. This is the podcast conversation about accelerating the transition to a sustainable, carbon-neutral society, and I’m your host, Mitch Ratcliffe. Thanks for joining the conversation today.
Let’s talk about the power and the uses of grand challenge programs to kickstart low-carbon industries and respond to the changing environment. Over the past several years, we’ve talked on the show with leaders of grand challenge programs designed to accelerate progress on humanity’s most difficult challenges, from pulling carbon out of the atmosphere to fighting rapidly growing wildfire threats in cities and rural communities. Many of these competitions have been launched by XPRIZE, whose leaders have shared on the show the stories of these competitions as they launched and unfolded.
Today is a chance to take stock, to look back and think about how climate markets, technology, and politics are changing fast, and how that makes this a good moment to ask the question: Are these programs designed to accelerate progress actually delivering that progress?
Our guest today designs XPRIZE’s climate bets. David Babson is executive vice president of the Energy, Climate, and Nature domain at the XPRIZE Foundation. Before XPRIZE, he was the executive director of MIT’s Climate Grand Challenges initiative and a program director at the U.S. Energy Department’s ARPA-E energy technology research agency.
His portfolio includes the largest incentive in prize history. In 2025, Mati Carbon received a $50 million grand prize for their enhanced rock weathering solution for capturing and drawing down carbon, and XPRIZE now reports that companies participating in its programs have raised $3.3 billion. That carbon removal win arrived just as the removal market hit serious turbulence, and as XPRIZE’s wildfire competition wrapped up with its top prize still unclaimed.
So we’re going to discuss what grand challenges can really accomplish, which winners continue to build and which stall, and what the reasons are, as well as the tensions inside a portfolio that funds both climate solutions and longer human lifespans. We’ll get to the conversation right after this brief commercial break. Stay tuned.
[COMMERCIAL BREAK]
Welcome back to Sustainability In Your Ear, and welcome, David Babson, to Sustainability In Your Ear. How are you doing today?
David Babson 03:10
I’m doing well.
Mitch Ratcliffe 03:11
I’m glad to have you here. You’ve run research portfolios at ARPA-E and MIT. What can a prize purse accomplish that a well-funded grant program can’t, or are they complementary?
David Babson 03:22
They’re absolutely complementary. The way that I think about it is that the value of these different mechanisms for promoting innovation is at different parts of the innovation supply chain, if you will. A prize is not a substitute for the very necessary investments that places like governments make into basic, applied, and advanced research. In fact, those types of investments are really valuable for establishing the innovation ecosystems and the technical capacities to eventually win prizes.
Where the prize is very valuable is somewhat downstream: translating technologies, ideas, and innovations that are coming out of academia and labs to market for scale. It challenges the innovators to imagine those technical capacities as solutions to global challenges, and then the visibility that the prize brings to those translations of technologies de-risks funding to flow to those innovators so they can imagine their uses in practice.
So I actually see them as very complementary, particularly when it comes to solutions in the energy and climate space that require rapid adoption of technologies in markets to have impact. Just having an energy solution or a climate solution is not valuable unless it can be de-risked and connected to markets to scale for impact. And that’s what the prize is actually very good at doing.
Mitch Ratcliffe 05:22
That comes through in the impact report that you all published recently. About 1,300 different organizations were catalyzed. The groups came together, apparently, because of their desire to compete in the competition.
What I’ve found in my work with public-private partnerships, in particular, is that impact investors are looking for that initial traction, and to a degree, the prize and the distribution of money within the prize group is that catalyst that says there’s a real opportunity for an impact profit, something that both does good and is profitable. How does the organization consult with the financial communities that are going to back these companies once your prize has been awarded? Is there a backroom conversation about that, for lack of a better way of putting it?
David Babson 06:10
Not an explicit backroom conversation about it, but the prize itself brings attention to the innovations that are coming out to win the competition. Oftentimes, as you’re noting, these impact investing communities exist, and they are looking for technologies to invest in to have impact.
What the prize is effective at doing is casting a wider net and surfacing the best solutions across the board, where there may have been silos in the past, or there may not have been transparency to individual investors about where to put their money. The prize is capable of elevating all of them, creating better visibility, and therefore, just by its inherent operation, creates better opportunities for investment capital to flow to the right types of teams to have greater impact more quickly.
So we don’t have explicit discussions with those types of investor communities to have them directly connected to individual prizes. But we often consult with investors and experts in industry to inform the metrics that we would want to have demonstrated, so that we know that when teams are winning our competitions, the demonstrations that they do are de-risking capital to flow to those innovators so that they can be translated to market.
Mitch Ratcliffe 07:47
We’re talking about growing industries, which of course means diversifying into a lot of specializations. Once you’ve got this kind of anchor winning team or teams, how does XPRIZE think about propagating the information that’s necessary for the rest of the industry to grow and fill in around them, in order to provide the kind of comprehensive geographic coverage and range of functions that are necessary for the industry to thrive? Is that something that you think about cultivating, like you would in agriculture?
David Babson 08:22
It is something that we think a lot about. With a few of the more recent prize competitions that we’ve run, we have also paired those competitions with a subsequent impact phase, which is designed to further build the community that has been established through the operation of the prize and connect the technologies that came out of the competition to the right types of markets and investors so that they can scale.
So that is one of the things that we’re thinking about in future competitions as well: not just running an innovation competition to surface new innovations, but how do we augment the community building that the prize provides as a way to also promote the back-end business models and industries that can scale those solutions for impact?
Mitch Ratcliffe 09:19
How would you describe the patterns you’re looking for that indicate that an organization can become that durable enterprise? What separates them from the rest? Have you got thoughts about that?
David Babson 09:29
I do have thoughts about it. In a lot of ways, the rigorous metrics that we set up when we’re designing the competition are informed by what experts believe would be the necessary demonstrations to actually generate a solution that is market viable. So a lot of it is very quantitative in terms of how we architect the competition.
But what we’ve also seen is that there are elements of winning teams that can’t always be controlled by just the scientific metrics. A lot of times, it’s the composition of the team, how diverse they are, and the unique mentality that the leaders of the team have in terms of their vision and their ambition. Those are parts that you can’t control for, but the prize model is very effective at also attracting the type of entrepreneurial, big-thinking individuals that actually tend to be behind some of the most successful companies.
Mitch Ratcliffe 10:40
Those big-thinking individuals often struggle with the transition from inventor. And to your point about the academic community often being the source of many of the teams that are competing, that’s not something that academics are necessarily good at. As part of the prize process, do you also begin to coach them on how to staff for the operators who are going to be able to translate the invention into a market success?
David Babson 11:04
Absolutely. On the front end, the prize itself sets a target that is typically beyond what researchers in an academic setting are imagining for what they’re doing. It gives them a way to imagine their technical innovations as scalable solutions to big problems, so that gets them excited to be in the competition. But you’re right: they’re not necessarily all business-minded or have the types of experience that would allow even very, very good solutions to become very strong companies and business models.
So one of the things that we have tried out recently, and it’s a model that we could replicate in future competitions as well, is an accelerator cohort in the carbon removal prize. It was optional for teams to opt into the cohort to get additional guidance and consulting from experts in startups and technology translation. That would help them think about the unique elements of their proposed carbon removal strategy, how they would connect it to markets, and how they would drive greater value for their solutions.
That is something that we can do as part of the competition, because we’re building a community of innovators that are striving toward a shared aim. Therefore, we can better define what an accelerator cohort looks like, so that the guidance that is provided is more effective at actually generating the right type of thinking for scaling the solutions that we’re interested in.
Mitch Ratcliffe 12:52
That kind of accelerator approach gets you ready for market competition, but it doesn’t always get you ready for the market in which you’re going to have to exist as an organization. It’s templated, and the specifics of any individual company’s success are very unique.
Let’s take Mati Carbon as an example. They won the $50 million prize. They are doing carbon drawdown using basalt ground up and mixed into farmers’ fields, but their success is really anchored in the carbon credit market’s growth. How does the prize work with those sources of carbon credit purchases, for instance, Meta or Microsoft, to connect them to these opportunities to make prize winners thriving organizations?
David Babson 13:38
There are some limitations to what we can do in that space. I think the uncertainty and the pullback in commitments to carbon credits and carbon markets is a challenge to the cohort of teams that competed in the carbon removal prize.
Ironically, I think one of the things that i
