The first major update of CTC’s carbon-tax model since 2021 is now in the books, calibrated to 2023 emissions and the putative emissions-reducing provisions of the Inflation Reduction Act. One result stands out: Without federal legislation mandating a robust national carbon tax, the U.S. won’t come close to achieving the hoped-for 50% decline in carbon emissions (from 2005 levels) in the reasonably foreseeable future.
A $20/$15 carbon tax could halve carbon emissions by 2035
A national carbon tax starting next year at $20/ton and rising annually by $15/ton will cut U.S. CO2 emissions in half from 2005 levels in 2035. To halve emissions by 2030 requires $25/ton for both the starting price and the annual rises.
A national carbon price that took effect in 2025 at $20 per (short) ton and rose by $15 per ton each year would, by 2035, halve U.S. emissions of carbon dioxide from fossil fuel combustion: from 6,120 million metric tons (“tonnes”) in 2005, the standard baseline year, to an estimated 3,068 million tonnes in 2035, according to CTC’s model (Excel spreadsheet, 2 MB). That computes to a 50% reduction (rounded from 49.9%).
[NB: The site hosting the Excel file is temporarily down, please check back soon.]
But without a national carbon price, our model projects U.S. emissions in 2035 of 4,606 million tonnes. That would be just 25% below 2005 emissions, putting the country only halfway to the 50%-reduction goal in 2035. And even that piddling progress entails pushing back the customary 2030 target for halving U.S. emissions to 2035, a 5-year delay.
To be fair, the “halving by 2030” goal is generally construed to encompass not just carbon dioxide but also methane, which is regarded as lower-hanging greenhouse-gas fruit on account of its relative concentration in more easily regulatable oil and gas extraction and transport. This January methane began to be subjected to emissions pricing, through a provision of the Inflation Reduction Act mandating that emissions above a certain threshold be taxed at a rate of $900 per tonne.
But even assuming an optimistic three-fourths reduction in methane and other non-carbon GHG’s, CO2 emissions from fossil fuel-burning would have to fall by 44% from 2005 to achieve an overall 50% reduction in U.S. greenhouse gas emissions. Without a national carbon price, the projected CO2 reduction from 2005 is just 17% in 2030 and, as noted, only 25% in 2035, according to CTC’s model.
Halving carbon emissions by 2030 requires a more heroic carbon tax, one starting at $25/ton in 2025 and rising annually by that amount
We also ran the CTC model to determine the carbon price level and trajectory required to halve U.S. 2005 carbon emissions by 2030 rather than 2035. Talk about a tall order! Here’s what the requisite carbon tax would look like:
- The carbon tax would take effect in 2025 (same as in the 2035 scenario).
- The initial price would be $25 per ton of CO2 rather than $20.
- The annual price rise would be the same $25/ton, rather than just $15/ton in the 2035 scenario. That means reaching triple digits in the tax’s fourth year.
- And — this is a bit technical — we’re relaxed the model assumption of the maximum annual tax rise to which the U.S. economy can fully react, from $20/ton previously to $25/ton.
It goes without saying that the present-day American political system isn’t equipped to enact and implement such an “heroic” (an adjective we prefer to “draconian”) carbon tax.
The still-lonely radical center
Prominent voices calling for carbon taxes beyond token amounts (e.g., $10 or $20 per ton with little or no increases) are precious few, not just in absolute terms but relative to the pre-2010 period in which climate concern was widespread and neither the left nor the right had been consumed by their respective demonizations: carbon pricing (on the left) or climate concern of any sort (on the right).
Indeed, here at Carbon Tax Center, we’ve traded in our web pages that previously celebrated carbon tax supporters for pages like Carbon Pricing and Environmental Justice, Progressives and Carbon Pricing, and Conservatives, all of them grouped under a heading of “Politics.” Each is essentially a litany of grievances and rejections of carbon pricing and/or climate action, period.
This chart, from CTC’s newly updated carbon tax model, shows the futility of looking for a single invention or regulation or subsidy to slash U.S. emissions. Fossil fuels suffuse our economy, making robust carbon pricing essential to achieving big across-the-board cuts.
This isn’t polarization, it’s a simultaneous disavowal by both ends of the political spectrum of the lone plausible transformational climate-preserving policy measure. (Rather than “ends” I should say “sides” of the spectrum, given that anti-pricing has spilled over from the confines of the respective extremes and now appears to occupy most of the two sides.)
Omens
Consider these two minor but telling signposts from the past week.
One was a NY Times “Sunday Review” guest essay last weekend, I’m a Young Conservative, and I Want My Party to Lead the Fight Against Climate Change, by one Benji Backer, founder-director of the American Conservation Coalition.
Alas, the essay was cut from the same generic cloth as other conservative calls to climate action. Here’s an excerpt:
We cannot address climate change or solve any other environmental issue without the buy-in and leadership of conservative America. And there are clear opportunities for climate action that conservatives can champion without sacrificing core values, from sustainable agriculture to nuclear energy and the onshoring of clean energy production.
Ho-hum. But, most strikingly, zero mention of carbon pricing — not even a nod to the revenue-neutral type such as fee-and-dividend that circumvents right-wing canards about government overreach by “dividending” the carbon revenues to households, thus correcting the market failure driving carbon emissions without “growing the government.”
So much for the right wing. On the left, I had the frustrating experience of meeting a director of an iconic American environmental organization at a public event and bonding with him over our shared dismay at the organization’s post-2016 submission to anti-carbon-pricing rhetoric . . . only to be ghosted when I tried to arrange a meet-up to possibly grow our newfound patch of common ground.
So much for dialogue in service of effective climate policy.
Can’t we bring U.S. emissions down sharply without carbon pricing?
Alas, no. U.S. emission progress perennially falls short of even modest hopes. Almost from the moment the 2022 Inflation Reduction Act — which CTC supported from the git-go — was enacted into law, it has bumped up against a calamity of transmission bottlenecks, supply-chain woes and high interest rates. Even worse, perhaps, is the legal-regulatory “default” against building almost anything, even essential elements of the clean-energy infrastructure the IRA was intended to unlock
(Just after this post went up, I came across NY Times columnist Ezra Klein and Atlantic staff writer Jerusalem Demsas’s trenchant dive into the permitting-resistance phenomenon. Their analysis traces much of today’s disabling red tape and NIMBYism to Democratic Party empathy that prioritizes concerns about marginalized constituencies over the common good. Audio version here, transcript here.)
And let’s not overlook the emergent hellspawns of energy demand like AI processing, cyber-currency computing and ever-larger SUV’s and pickup trucks driven ever more miles, all of which threaten to pile on new carbon emissions almost as fast as incumbent emissions are removed.
As we’ve argued in post after post — just scroll through our monthly archives — these and other decarbonization derailments would be greatly alleviated by the robust carbon taxes we scoped above. Pricing the climate benefits of reduced fossil fuel use into the vast array of alternatives — from clean energy to all the ways of using less — will raise their profitability and, before long, bend society’s defaults toward replacing fossil fuels.
Our updated carbon-tax model shows that U.S. carbon emissions fell by 2.3% from 2022 to 2023. If there weren’t a climate emergency, that might qualify as a decent win. But in our real, overheating world, that rate doesn’t come close to the 4.1% compound annual decline needed to halve 2005 emissions by 2035, much less the 6.9% annual emissions shrinkage required to meet the same goal in 2030.
The insufficiency of even the best-intentioned policies and programs to meet necessary carbon targets without robust carbon taxing can’t be hidden indefinitely. The carbon tax reckoning awaits.

Walmart (WMT) Expands EV Charging and Boosts Renewable Energy in Its Net-Zero Playbook
Walmart (NYSE: WMT) is stepping up its clean energy and emissions game across the United States. Shoppers want to save money and live more sustainable lives, and Walmart sees a big role for itself in that shift. With a store or club within 10 miles of nearly 90% of Americans, the retailer believes it is perfectly placed to support the country’s move to cleaner transportation.
From expanding EV charging access to using more renewable power and electrifying its delivery fleet, Walmart is building a lower-carbon future that also brings long-term savings and stronger resilience.
Charging Up America: Walmart’s Big EV Push
Walmart wants to make owning an electric car easier for millions of people. The company plans to build its own fast-charging network across thousands of Walmart and Sam’s Club locations by 2030. This will add to the nearly 1,300 chargers already running at more than 280 stores today.
The goal is simple: remove the fear of not finding a safe and reliable place to charge. Walmart’s well-lit parking lots offer an easy place to plug in while customers shop, grab groceries, or pick up essentials. And in true Walmart style, the company aims to offer low-cost charging to help families save on transportation—the second-largest expense for most households.

Greener Deliveries and Next-Gen Fleet
Transportation is one of Walmart’s toughest emissions issues. In 2024, the company’s fleet made up 24.9% of Scope 1 emissions and 14.4% of total operational emissions. As Walmart brings more logistics in-house and grows its business, fleet emissions may rise in the short term.
Yet Walmart is preparing for a cleaner future. It’s partnering with GM, Ford, and Canoo to electrify delivery vehicles. Many Walmart+ deliveries already use electric vans.
- They are also testing heavy-duty battery trucks, hydrogen fuel cell vehicles, and renewable diesel.
- Walmart is rolling out liquid hydrogen-powered forklifts and recently opened Latin America’s first industrial-scale renewable hydrogen plant in Chile.
- Electric yard trucks are already delivering major gains—cutting emissions by more than 75% per hour compared to diesel models.
These tests matter. They help shape the future of Walmart’s fleet, especially as long-haul truck solutions may not mature until the 2030s.
As more drivers go electric, the re network will add much-needed charging options nationwide. Even rural areas, which often lack EV infrastructure, will benefit. Walmart sees this as a smart business move and a natural extension of its mission to help customers live better and more sustainably.
Smart Stores with Clean Energy
Walmart’s clean energy plan centers on four ideas: access, cost, resilience, and emissions cuts. Because its stores rely more than ever on electricity and digital systems, stable power is essential. So Walmart is investing in new technology to identify power risks, upgrade monitoring tools, and strengthen connections to the grid.
Real-time energy monitoring across thousands of facilities helps Walmart track usage and operate more efficiently. These insights will matter even more as automation grows across the company’s operations.
Walmart is also adding more on-site power. Solar panels, wind systems, and battery storage help stores stay open during outages and lower long-term energy bills. Between 2024 and 2030, it aims to support up to 10 gigawatts of new clean energy capacity.
The company is already making progress. In 2024, renewable energy met 48.5% of Walmart’s global electricity needs. This brings the retailer close to its goal of 50% renewable power by 2025 and puts it on track for 100% by 2035. By the end of 2024, its U.S. operations had 166 MW of onsite solar across 325 facilities and 10 MW of energy storage at 44 locations.

Achieving Net-Zero Emissions
Walmart is working toward zero emissions across its global operations (Scope 1 and 2) by 2040. These emissions come from transport fuels, refrigeration, heating, and electricity use.
The company has reduced its emissions intensity by 47.4% since 2015, but annual emissions can still vary. In 2024, Walmart’s Scope 1 and 2 emissions rose by 1.1%. Growth in U.S. transportation and lower renewable energy output in Mexico and Central America—due to extreme heat and drought—played a big role.
Still, global operational emissions remain 18.1% lower than the 2015 baseline. But progress won’t always be smooth. Policies, infrastructure limits, equipment shortages, and slow advances in low-carbon trucking technology create challenges. Walmart has noted that meeting its 2025 and 2030 targets may take more time.
Even so, Walmart keeps improving. New buildings and remodels use efficient lighting, HVAC systems, and refrigeration. The company is replacing older equipment with high-efficiency models and testing refrigeration and HVAC systems with lower global warming impact. These upgrades support both sustainability and cost savings.

Walmart (WMT) Q3 FY2025 Highlights
Walmart Inc. posted Q3 FY2025 revenue of $179.5 billion, up 5.8% from last year and beating estimates by 1.1%. Same-store sales rose 4.5%, fueled by strong e-commerce and retail growth, with adjusted EPS at $0.62—above expectations. The company raised its full-year sales outlook amid steady demand and efficiency gains.
Additionally, WMT stock hit near-record highs but with a “Moderate Buy” rating from analysts, targeting 6-9% upside. Growth drivers include e-commerce, consumer resilience, and clean energy bets like EV fleets and chargers.
The goals are bold: zero operational emissions by 2040 and 100% renewable power by 2035. Yet Walmart’s scale, resources, and willingness to innovate give it a powerful role in America’s clean energy transition. And ultimately, these steps help customers live better, save more, and make sustainable choices that fit their everyday lives.

Sierra Madre: Breathing New Life into Mexico’s Silver and Gold Heartland
Disseminated on behalf of Sierra Madre Gold & Silver Ltd.
Mexico has been a cornerstone of global silver and gold production for centuries, with historic mining regions such as Zacatecas, Durango, and the Sierra Madre belt supplying the world with these precious metals. Mining represents nearly 2.5% of Mexico’s GDP and produces significant export revenue.
However, decades of underinvestment and declining output from aging mines led to a slowdown in production growth. Today, a new wave of modern mining companies is reinvigorating Mexico’s silver and gold industry, bringing capital, modern technology, and strict environmental practices to historic mining regions.
Among these companies, Sierra Madre Gold & Silver Ltd. (TSXV: SM | OTCQX: SMDRF) is emerging as a standout player, spearheading the revival of Mexico’s rich Temascaltepec district with its La Guitarra Mine.
Mexico’s Silver and Gold Renaissance: Strategic Importance
Mexico remains the world’s largest silver producer, contributing roughly 23–25% of global output in 2024, with total production between 5,800 and 6,300 tonnes. The surge in industrial demand for silver is reshaping its role from primarily a jewelry and investment metal to an essential material in the clean energy transition.
- With silver prices stabilizing around US$28 per ounce in 2025 and climbing above $50 in October, mid-tier producers like Sierra Madre stand to increase shareholder value while supporting rural economies.
Each solar panel consumes about 20 grams of silver, while electric vehicles require up to 50 grams. Analysts predict that by 2030, global silver demand will exceed 1.2 billion ounces annually, highlighting the need for stable, modern supply sources.
Mexico’s combination of skilled workforce, supportive regulations, and modern infrastructure makes it an attractive destination for exploration and investment. Sierra Madre’s work at La Guitarra, along with exploration at Tepic, exemplifies how new companies are turning dormant assets into engines of growth for the next decade.
Reviving La Guitarra: History Meets Modern Mining
The La Guitarra Mine has a storied history dating back to colonial times, producing both gold and silver under different owners, most recently First Majestic Silver. After a period of care and maintenance, Sierra Madre acquired the mine in 2023 with a clear strategy: restart production (achieved January 2025) and expand output.
The mine comes equipped with a 500-tonnes-per-day processing plant, permitted underground workings, and nearby infrastructure including roads, water, and power. With C$19.5 million in fresh capital and a skilled technical team, it has achieved a full-scale restart, with commercial production announced in January 2025.
- By 2027, the company aims to up to triple production to 1,500 tonnes per day, leveraging smart mine design and local partnerships to keep costs low while ramping output efficiently.
Furthermore, their leadership blends local mining expertise with strong capital markets knowledge, enabling efficient project execution. La Guitarra’s high-grade veins, clear exploration targets, and straightforward permitting process make it one of Mexico’s most promising silver-gold projects.

Commitment to Responsible Mining
Sierra Madre embodies a new generation of environmentally and socially responsible miners. The company is upgrading waste and water systems to modern standards, reclaiming tailings efficiently, and minimizing water usage. Open communication with local communities, clear permitting, and strong ESG practices reinforce its credibility with stakeholders and investors.
Modernization at La Guitarra is as much about responsible operations as it is about increasing output. This focus on sustainability aligns with global investor expectations while strengthening its long-term partnerships.
Sierra Madre holds one other project in Mexico’s Sierra Madre mineral belt:
- Tepic Project (Nayarit): High-grade epithermal gold-silver deposit with near-surface mineralization and strong exploration upside.
By focusing on assets with existing infrastructure and clear development paths, Sierra Madre reduces operational risk compared with early-stage exploration projects.
Industrial Demand Drives Silver’s Strategic Role
Silver’s function has evolved beyond traditional uses. Its high conductivity and reflectivity make it essential in solar panels, EV batteries, 5G networks, and electronics. Industrial demand is rising sharply: in 2024, industrial silver consumption reached 680.5 million ounces, accounting for over 30% of total usage, and solar energy alone represents a growing share.
The EV market further drives demand, with each vehicle requiring up to 50 grams of silver. Rising industrial requirements, combined with structural supply deficits, position companies like Sierra Madre to benefit from near-term production growth.
Global silver production is struggling to keep pace. In 2024, total output was roughly 819.7 million ounces, barely a 1% increase over the previous year. A projected 117.6 million-ounce supply deficit in 2025 underscores the need for reliable producers in Mexico’s rich silver belt.

Leveraging Gold’s Enduring Value in a Record-Price Era
Gold remains a cornerstone of stability. Prices are expected to hold above US$3,000 per ounce, supported by investment demand, central bank buying, and geopolitical uncertainty. In Q2 2025, total gold demand rose 3% year-over-year, reaching 1,249 tonnes, while mine production matched this growth, reflecting a healthy market balance.
At La Guitarra, underground mining at the high-grade Coloso vein started in April 2025, increasing production potential and improving grades. The company is upgrading milling systems to improve recovery rates and lower costs, capitalizing on record-high gold prices.
Strong Operational and Financial Performance
- In Q2 2025, Sierra Madre sold 173,562 silver-equivalent ounces: 66,011 ounces of silver and 1,048 ounces of gold, generating 168,535 AgEq ounces at an average price of US$30.10 per AgEq ounce.
The Coloso Mine is ramping up to 150 t/d by year-end, while underground development at the Nazareno Mine has already delivered over 700 tonnes of mineralized material to the Guitarra mill, with grades exceeding prior estimates.
The company raised C$19.5 million in mid-2025 to expand throughput, launch a +20,000-meter exploration program across its mineralized belt, and target high-grade zones in the East District. Strong revenue, cash position, and working capital support ongoing operations and exploration, providing a solid financial foundation for growth.
Silver continues to show upside potential. With a gold-to-silver ratio of 70:1, silver is currently undervalued relative to gold. Combined with rising industrial demand and tight supply, this positions Sierra Madre’s dual-metal strategy to capitalize on both growth and stability. Analysts project that silver deficits will persist, reinforcing the value of near-term production assets like La Guitarra.

Two Metals, One Growth Strategy
Sierra Madre’s dual-metal approach combines gold’s stability with silver’s growth potential. Gold anchors financial security, while silver leverages rising industrial demand. This strategy enables the company to maximize shareholder value while maintaining operational resilience.
Phased Expansion Plan
Sierra Madre is executing a two-phase expansion at La Guitarra:
- Phase 1 (Q2 2026): Increase capacity to 750–800 t/d with equipment upgrades, including a new cone crusher and ball mill.
- Phase 2 (Q3 2027): Ramp up to 1,200–1,500 t/d with additional crushing circuits, producing finer material and improving recovery rates.
No additional permits are required, and the expansion will be fully funded from existing cash flow, ensuring self-sustained growth.
Final Take: Why Sierra Madre Is Poised to Deliver Silver and Gold
Sierra Madre Gold & Silver is at the forefront of Mexico’s silver and gold revival. With a mix of production-ready assets, exploration upside, and strong financial backing, the company is well-positioned to benefit from rising demand, structural supply deficits, and supportive market dynamics.

La Guitarra combines history, infrastructure, and timing for near-term production, while Tepic offers significant exploration potential. Sierra Madre’s dual-metal strategy balances stability with growth, leveraging gold’s safe-haven value and silver’s industrial demand.
As global demand for clean energy technologies, electric vehicles, and industrial applications rises, Sierra Madre is uniquely equipped to deliver both silver and gold. Its operational asset, responsible mining practices, and strategic expansion plan position it as a leading junior miner in Mexico’s most productive silver-gold belt.
In short, Sierra Madre has not just restarted a mine—it is breathing new life into Mexico’s historic silver and gold heartland while positioning investors to benefit from a transformative decade in precious metals.

Frontier Backs Climate Startup Reverion for 96,000 Tons of Biogas-Based Carbon Removal
Climate startup Reverion, a German company specializing in biogas-based carbon removal, has secured several major offtake agreements through Frontier, the advanced carbon removal buyer coalition. The deals mark a significant milestone for the company as it works to commercialize its solid oxide fuel cell (SOFC) technology, which captures and permanently stores CO₂ while producing clean electricity.
Under the new commitments, Frontier buyers—including Google, McKinsey, H&M Group, Autodesk, Workday, and others—will pay $41 million for 96,000 tons of permanent CO₂ removal between 2027 and 2030.
Frontier’s carbon removal portfolio

These agreements strengthen the growing belief that biogas-based carbon removal can be both scalable and economically attractive when combined with high-efficiency energy production.
How Reverion’s Fuel Cell System Turns Biogas into Permanent Carbon Removal
Reverion, a 2022 spin-off from the Technical University of Munich, has created a system that generates clean electricity and captures carbon from biogas at the same time. Farmers produce biogas by placing manure, crop leftovers, and food waste into anaerobic digesters. These digesters create a gas mix that contains methane and CO₂.
- The company’s solid oxide fuel cell (SOFC) converts the methane in this gas directly into electricity with very high efficiency.
- During this reaction, the carbon in the gas separates into a pure CO₂ stream.
- The system then liquefies this CO₂ and sends it for permanent geological storage.
Traditional biogas systems burn the gas in engines, lose energy, and release most of the carbon back into the air. Some even leak methane, which traps far more heat than CO₂. Reverion avoids these problems by capturing carbon from both methane and CO₂ in the biogas. As a result, the system increases the amount of carbon removed and cuts emissions at the source.
By pairing efficient power generation with full carbon capture, Reverion turns everyday biogas into a dependable pathway for long-term carbon removal.

Energy, Hydrogen, and New Revenue Streams for Farmers
The press release highlighted that, today, more than 120,000 biogas plants operate worldwide, but many still use old engines with low efficiency. And Reverion’s SOFC gives farmers a major upgrade. It reaches about 74% fuel-to-electricity efficiency—one of the highest levels in the industry. This lets farmers produce more electricity from the same biogas, lower their energy bills, and earn extra money by selling clean power.
The system also adds flexibility. When electricity prices drop, often during times of strong wind and solar output, the fuel cell can run in reverse to make green hydrogen. Farmers can sell this hydrogen or use it on their own farms, creating another income source.
By delivering clean energy, flexible operation, and permanent carbon removal, Reverion offers a strong alternative to combustion engines and renewable natural gas upgrading systems.
Frontier Unlocks: Why BiCRS Matters in Carbon Removal Portfolios
Biomass Carbon Removal and Storage (BiCRS) is emerging as a strong contender for long-duration carbon removal. It includes several pathways such as BECCS, bio-oil sequestration, biomass injection, and now biogas-based fuel cell systems.
Frontier explains how BiCRS stands out for the following reasons:
- Lower costs: Plants capture CO₂ naturally and at no cost. Many BiCRS systems also use existing waste streams, which reduces input costs.
- Clear verification: Technologies like BECCS and biomass injection are easier to measure and verify compared with more experimental removal pathways.
- Near-term scalability: Bio-oil and biomass injection can grow quickly, helping meet the rising demand for carbon removal supply.

However, BiCRS is not without challenges. The biggest concern is sustainable biomass sourcing. Poor practices—such as removing too much crop residue, clear-cutting forests, or heavy fertilizer use—can harm biodiversity, damage soils, or increase emissions. Because of these risks, carbon removal purchasers must follow strict sustainability guidelines when sourcing biomass.
There is also a durability question for some BiCRS methods. Some biomass burial or sinking approaches could decompose over time, reversing the stored carbon. Frontier funds several R&D projects to evaluate long-term durability.
Finally, the BiCRS market is expected to be highly fragmented. Feedstock types differ by region, and the best removal pathway varies based on geography, transportation options, and local policy. Most BiCRS facilities also operate at a modest scale, meaning the market will rely on many distributed projects rather than a handful of giants.
Even so, BiCRS delivers several co-benefits. These include on-site clean energy production, lower fossil fuel use, reduced methane emissions, nutrient recycling for croplands, and destruction of harmful pollutants like PFAS.
Why Reverion’s Model Stands Out
Reverion’s approach offers compelling advantages that support its rapid market adoption:
- Large potential impact: With over 120,000 biogas sites worldwide, the theoretical removal potential from biogas could exceed 2 gigatons per year by 2040, according to IEA projections. Reverion could capture a meaningful share of this, especially alongside other BiCRS technologies.
- Full-stream carbon capture: Most systems capture only the CO₂ portion of biogas. Reverion captures carbon from both CO₂ and methane, effectively doubling the removal impact.
- World-class electrical efficiency: Its 74% efficiency ranks among the highest globally, increasing economic returns for operators.
- Low methane leakage: Because methane is converted on-site, the system avoids pipeline leaks often associated with renewable natural gas.
- Strong market demand: Reverion already holds 60 pre-orders and 120 letters of intent, signaling strong momentum.

As the world accelerates efforts to scale permanent carbon removal, technologies like Reverion’s offer a promising path—combining high-efficiency clean energy production with durable, verifiable carbon storage at biogas sites around the world.
