Climeworks, a Swiss-based pioneer in direct air capture (DAC) technology, has raised $162 million in additional equity funding—marking the largest carbon removal investment globally so far in 2025. The latest round brings the company’s total equity funding to over $1 billion, reinforcing its position as a leader in the carbon removal sector.
The financing round was led by BigPoint Holding and Partners Group, alongside continued support from existing investors. The fresh capital will be directed towards further development and scaling of Climeworks’ DAC technology, with the aim of reducing the cost of carbon removals.
“This funding strengthens our ability to drive down costs and push forward innovation,” said Christoph Gebald, co-CEO and co-founder of Climeworks. “Direct Air Capture has gone from experiment to essential… crossing the $1 billion equity mark isn’t just a milestone—it shows that carbon removal is real, needed, and here to stay.”
Climeworks has already made significant strides in improving the efficiency and scalability of its operations. Its first commercial plant, Orca, validated its initial approach, while the larger Mammoth facility is now enabling broader testing and scale-up of new technologies. Key advancements include a doubling of energy efficiency, increased throughput, and extended filter lifespan.
The investment will also support Climeworks’ efforts to diversify and expand its carbon removal portfolio. The company is offering blended solutions that combine nature-based, hybrid, and technical approaches to meet the evolving needs of businesses seeking to offset their emissions.
With more than six million tonnes of carbon removal capacity already secured, Climeworks is positioning itself to meet both current and future demand. Market analysts project the carbon removal sector could reach $80 billion by 2030 and grow to $1 trillion by mid-century.
