Direct Air Capture Pioneer Climeworks Cuts Jobs as Carbon Plants Fall Short of Targets
Carbon Capture's Moment of Truth: Climeworks Stumble Signals Industry Inflection Point
In the frigid landscape of Iceland, where geothermal energy bubbles beneath volcanic soil, Climeworks' direct air capture plants stand as modern monuments to climate ambition.
Did you know? Direct Air Capture (DAC) is a cutting-edge technology that pulls carbon dioxide (CO₂) directly from the air to help combat climate change. Using chemical solutions or solid materials, DAC systems capture CO₂ and either store it underground or repurpose it for industrial use. Although still expensive and energy-intensive, DAC is considered a key tool for achieving net-zero emissions by removing carbon that’s already in the atmosphere—something traditional emissions reductions can’t do alone.
The Zurich-based carbon dioxide removal pioneer, once the darling of climate tech investors and corporate sustainability programs, now faces a reckoning that could reshape the entire carbon removal landscape. With significant layoffs underway and plant performance falling dramatically short of targets, the company's struggles offer a rare window into the structural challenges facing an industry critical to global net-zero aspirations.
The Performance Gap: Orders of Magnitude Off Target
The numbers tell a stark story. Climeworks' newer Mammoth plant in Iceland, designed to capture 36,000 tons of CO2 annually, managed to sequester just 105 tons in its first ten months of operation—less than 1% of its designed capacity. Since beginning operations in Iceland in 2021, the company has captured approximately 2,400 carbon units total, far below the 12,000 units company officials initially projected.
Did you know? In carbon removal, a carbon credit—also known as a carbon unit—represents one ton of carbon dioxide (CO₂) that has been actively removed from the atmosphere and securely stored. These credits are generated by projects like Direct Air Capture, reforestation, or biochar, and are verified to ensure the CO₂ is permanently taken out of the carbon cycle. Companies buy these credits to offset their emissions and meet net-zero goals, making carbon credits a key tool in funding and scaling climate solutions.
Perhaps most telling: Climeworks cannot even offset its own carbon footprint. The company emitted 1,700 tons of CO2 in 2023 while removing less than that amount, undermining its fundamental value proposition.

"What we're witnessing isn't just a company struggling with scale-up problems, but fundamental thermodynamic and economic barriers that the entire direct air capture sector faces," said an energy transition analyst at a major European investment bank. "The laws of physics don't bend to accommodate business plans or investor expectations."
Did you know? Direct Air Capture (DAC) faces a major thermodynamic challenge because extracting carbon dioxide (CO₂) from ambient air—where it exists at just 0.04% concentration—requires a lot of energy. According to the laws of thermodynamics, separating such a dilute gas demands significant work, especially to regenerate the chemical materials that capture the CO₂. While the theoretical minimum energy needed is about 250 kWh per ton of CO₂, real-world systems often use four to eight times that amount, making clean, efficient energy sources essential for scaling DAC technologies sustainably.
Financial Realities Force Brutal Reset
The financial picture appears equally challenging. Jan Wurzbacher, co-founder and managing director, confirmed that "significantly more than 10%" of Climeworks' 498-person workforce faces elimination in the coming weeks as "our financial resources are limited." The consultation process for these cuts has been concluded.
Behind these layoffs lies a troubling balance sheet. The company's Icelandic subsidiary reported negative equity of nearly $30 million in 2023. This operation relies entirely on funding from its Swiss parent, with outstanding obligations approaching 5 billion Icelandic krónur. Management has already been forced to take a $1.4 million depreciation charge on the underperforming Orca machine in 2023.
The precarious situation extends beyond Iceland. Climeworks' planned U.S. expansion—backed by a $500 million Department of Energy commitment for a Louisiana facility expected to create 469 jobs—now sits in limbo under the Trump administration's climate spending reassessment.
Industry-Wide Challenges or Existential Crisis?
Wurzbacher maintains that despite these setbacks, Climeworks remains "the best-capitalised company in this sector" with CHF800 million ($970 million) in funding secured to date. However, the company's own projections reveal the magnitude of the challenge: reaching its goal of removing one billion tonnes of CO2 annually by 2050 would require approximately 1,000 large plants and an estimated CHF1-2 trillion in additional financing.
The technical and economic hurdles facing direct air capture extend well beyond Climeworks. The technology requires enormous amounts of energy, creating what critics call a "pointless fight against entropy."
Did you know? Entropy—a measure of disorder—plays a key role in the energy challenge of Direct Air Capture (DAC). Since CO₂ is only a tiny fraction of the air, its molecules are widely dispersed, creating a high-entropy state. DAC works by reversing this natural disorder to isolate and concentrate CO₂, which requires a significant amount of energy. The more diluted and disordered the CO₂, the more energy it takes to pull it out of the air—making entropy a hidden but fundamental hurdle in scaling DAC efficiently.
Even when powered by renewable energy, DAC facilities must compete with data centers and other emerging technologies for limited clean power resources.
A European survey highlighted the sector's broader struggles: only 26% of carbon dioxide removal startups reported satisfaction with customer lead generation, while a mere 20% were satisfied with conversion rates. Just 22% found non-dilutive funding accessible.
Table: Summary of Critical Challenges Confronting Carbon Dioxide Removal (CDR) Startups
| Challenge Category | Key Issues | Notable Statistics/Facts |
|---|---|---|
| Funding & Financial | - Insufficient non-dilutive funding- Bureaucratic grant processes- Investor hesitancy on technology risk | - Only 22% of European CDR startups find non-dilutive funding accessible- Just 10% can access funding quickly enough- CDR startups represent only 1.1% of climate tech funding |
| Market Development | - Poor lead generation- Low conversion rates- Complex sales processes- Blended B2B/B2C market complications | - Only 26% satisfied with lead generation- Just 20% satisfied with conversion rates- Market oversaturation with 800+ startups competing |
| Technical & Scaling | - Extremely high scaling requirements- Prohibitive costs- CO₂ sourcing bottlenecks- Performance validation challenges | - Need 1,300x growth by mid-century- Current DAC costs: $600-$1,000 per ton (target: $100)- Must scale from thousands to hundreds of thousands of tons captured annually |
| Regulatory & Permitting | - Complex permitting processes- Evolving governance structures- Lack of CDR-specific policies | - Even research and pilot projects face significant permit barriers- Regulatory uncertainty impacts investment and planning |

"The carbon removal industry is fighting a three-front war," explained a climate finance specialist who has advised several DAC startups. "They need technological breakthroughs to reduce costs, policy certainty to create stable demand, and patient capital willing to fund a decade-long journey to profitability. Right now, they're losing on all three fronts."
Strategic Implications for Investors and Climate Finance
For financial markets, Climeworks' stumble represents both warning and opportunity. The collapse of climate finance startup Aspiration Partners in April 2025, which filed for Chapter 11 bankruptcy with approximately $170 million in outstanding debts, signals mounting pressure across the sector.
Corporate credit buyers, particularly technology giants like Microsoft and Stripe that have been the primary supporters of engineered carbon removal, will likely demand stricter performance milestones and verification protocols moving forward.
This could accelerate industry consolidation, with smaller DAC startups facing what one analyst called a "Darwinian cull."
Yet paradoxically, this moment of crisis may create long-term structural improvements. Valuations across carbon-removal startups will reset to more realistic levels. Policy makers, confronted with the gap between ambition and achievement, may clarify long-term incentives and verification standards. Cash-rich strategic investors—particularly oil and gas majors seeking to diversify—could acquire valuable intellectual property and infrastructure at discounted prices.
"This is how nascent industries mature," noted a sustainability portfolio manager at a major asset management firm. "The first wave of biofuels companies largely failed in the early 2000s, but they laid the technical and policy groundwork for today's successful producers. Something similar could happen with carbon removal."
Table: Key Lessons from the Biofuel Industry for the Carbon Removal Sector
| Lesson Area | Biofuel Experience | Carbon Removal Implication |
|---|---|---|
| Technology Hype vs. Reality | Early excitement led to overpromising and underdelivery | Be realistic about scalability, costs, and environmental performance |
| Lifecycle Carbon Accounting | Lifecycle emissions (e.g., land use) undermined climate benefits | Ensure rigorous, full-scope carbon accounting |
| Policy and Incentives | Industry growth driven by mandates and subsidies | Strong policy frameworks and incentives are essential for scale |
| Land Use and Sustainability | Feedstocks competed with food crops and ecosystems | Avoid competition with agriculture and prevent ecological harm |
| Infrastructure and Integration | Growth limited by distribution and blending challenges | Plan for CO₂ transport, storage, and integration from the start |
| Public Perception and Trust | Credibility eroded due to unintended consequences and misinformation | Prioritize transparency, verification, and proactive community engagement |
Investment Strategies Amid the Uncertainty
For investors seeking to navigate this volatile landscape, several approaches offer asymmetric risk-reward profiles. Infrastructure supporting carbon dioxide transport and storage—including salt-cavern hubs and Class VI wells—will retain value regardless of which specific capture technologies ultimately succeed.
Forward-looking investors are also securing long-term renewable power purchase agreements, anticipating scarcity as AI-driven data centers compete for green electricity.
Verification software and carbon credit insurance services represent another "picks and shovels" opportunity independent of any specific capture technology.
For direct exposure to capture technologies, selectivity becomes crucial. Only companies with cash runways exceeding 24 months and clear paths to strategic partnerships merit consideration in the current environment.
Climeworks itself remains viable if it can secure a strategic partner within the next year. Four scenarios appear most likely: a structured recapitalization led by an energy major (40% probability), government intervention through a European green industrial fund , an order-book driven rebound fueled by Fortune 500 buyers , or an orderly wind-down with technology assets sold to engineering consortiums .
As the carbon removal industry navigates this turbulent period, one thing remains clear: Climeworks' current struggles represent not the death knell of direct air capture, but its transition from theoretical promise to practical reality—with all the painful adjustments such transitions entail.
