Largest carbon removal investment round globally year to date
Climeworks raises USD 162M to scale up technology
Climeworks, the global pioneer in Direct Air Capture (DAC) technology and leading provider of holistic carbon removal portfolios, has achieved a significant milestone by securing USD 162 million in additional equity funding — marking the largest carbon removal investment of 2025 to date globally.
This financing round underscores Climeworks’ commitment to scaling up and perfecting its cutting-edge technology to help significantly reduce the cost of carbon removals. This latest investment takes the company’s total funding since inception to over USD 1 billion, further solidifying its position as the industry leader.
Main investors of the funding round were BigPoint Holding and Partners Group, with additional backing mainly from other existing investors, reaffirming their strong commitment to Climeworks. This unwavering support underscores deep confidence in the company’s technology leadership, commercial momentum, and ambitious long-term mission to revolutionize carbon removal.
Developing best-in-class technology
The new capital will fuel the continued development of Climeworks’ best-in-class DAC technology to bring down the cost of removals. Climeworks has achieved major milestones in scaling its groundbreaking technology. Its first plant, Orca, successfully validated the company’s approach. In addition, the second plant, Mammoth, is driving further advancements by enabling scaling and large-scale testing of new removal technologies.
The company has already demonstrated significant advancements that will make its processes more efficient, including doubled energy efficiency, increased throughput, and a much longer filter material lifespan—key progress toward making the world’s first profitable direct air capture plant a reality.
Building the market with a more diverse removals portfolio
The funding will also allow Climeworks to continue expanding its carbon removal portfolio, providing tailored, blended solutions that help companies begin investment in removals, spread risk and progressively move up the quality curve.
Climeworks continues to expand its carbon removal portfolio offering as the number one carbon removal player. As demand grows, companies increasingly rely on nature-based and hybrid engineered solutions for near-term removal needs while increasing their focus on technical removals over time. Climeworks is uniquely positioned to meet both short- and long-term demand with a global portfolio that already includes > 6 million tons of secured supply. According to analysts, the carbon removal market is poised for a potential to reach 80 billion USD by 2030, growing to a trillion USD by 2050.
Christoph Gebald, co-CEO and co-founder of Climeworks says: "Direct Air Capture has gone from experiment to essential—and we’re focused on scaling it by driving down costs and pushing innovation. Our hybrid model builds long-term demand while generating cash flow today, helping us grow a market that investors now see as inevitable. Crossing the $1 billion equity mark isn’t just a milestone—it shows that carbon removal is real, needed, and here to stay.”
