• $69M funding led by Decarbonization Partners and Blume Equity.
• Target: 1M tons CO2 removed by 2030, expanding across Europe, North America, and Asia-Pacific.
• Existing Support from Siemens, Verve Ventures, ACE Ventures, Holcim, and UBS.

Neustark, a Swiss carbon removal company, has raised $69 million to expand its operations globally. Led by Decarbonization Partners and Blume Equity, the funding aims to remove 1 million tons of CO2 by 2030. Existing supporters include Siemens, Verve Ventures, ACE Ventures, Holcim, and UBS, with the latter providing debt financing.

Neustark, a leading carbon removal provider based in Switzerland, has secured $69 million in a funding round to accelerate its growth and impact in the carbon dioxide removal (CDR) market. The growth equity round was led by Decarbonization Partners, a collaboration between BlackRock and Temasek, and climate tech investor Blume Equity.

“We turn the world’s largest waste stream – demolition concrete – into a carbon sink,” said Johannes Tiefenthaler, co-CEO and founder of Neustark. “This growth investment will take us into the next exciting phase of our mission, helping us to further scale our impact across Europe, enter new markets in North America and Asia-Pacific, and develop new solutions to store even more CO2 in mineral waste streams.”

Neustark’s innovative technology captures CO2 from biogas plants and binds it in mineral waste through an accelerated mineralization process, creating durable carbon sinks from demolition concrete and other mineral wastes. This process permanently stores CO2 for hundreds of thousands of years.

Meghan Sharp, Global Head & Chief Investment Officer of Decarbonization Partners, remarked, “With carbon capture, utilization, and storage being one of our key investment focuses, we believe that we have found a perfect partner to help scale the industry – and ultimately its decarbonization impact – in the years to come.”

Neustark’s technology is already operational at 19 sites across Switzerland, Austria, Liechtenstein, and Germany, with 40 more plants under construction in Europe. The company has sold nearly 120,000 tons of carbon removal to date, serving clients like Microsoft, UBS, and NextGen, with all projects certified under the Gold Standard.

“The CDR market is experiencing substantial growth, driven by high-quality and durable carbon removal solutions and a surging demand for trusted carbon credits,” added Tiefenthaler. “Despite this, we need to exponentially accelerate the removal of CO2 if we want to reach net zero goals by 2050.”

With this significant funding and the strategic support from Decarbonization Partners and Blume Equity, Neustark is poised to enhance its offerings, expand its team, and meet the increasing global demand for scalable, measurable, and commercially viable carbon removal solutions.
