SWISS Launches New Partnership with neustark for Permanent Carbon Removal

SWISS has announced the launch of a long-term strategic partnership with tech pioneer neustark, the first company in the world to store carbon dioxide generated by biogas facilities in demolished concrete to remove it permanently from the atmosphere.

On Tuesday (August 26, 2025), Swiss International Air Lines (SWISS) announced the start of a new long-term strategic partnership with Swiss-based tech pioneer neustark, the first company in the world to store carbon dioxide generated by biogas facilities in demolished concrete to remove it permanently from the atmosphere.  Neustark has already demonstrated the viable benefits of its new technology, and the new SWISS partnership should help the innovation to be further refined and internationally expanded as a key element in achieving the world’s carbon reduction goals.,

In Tuesday’s announcement, SWISS’ CEO, Jens Fehlinger, said

“Our journey to net zero demands actions as well as words.  Switzerland is a land of innovation. And we’re proud to help carry this strength out into the world.  In teaming up with neustark, we’re supporting a Swiss idea that can have a global impact.  Permanent CO₂ removal is key to the future of the aviation sector; and we are intentionally getting involved in this technology as early as possible, to help scale it up and drive its further development. And as the first airline in the world to do so, we’re saying: At SWISS, we don’t wait; we lead the way.”

Also commenting on the new decarbonization partnership, neustark’s Co-Founder and Co-CEO, Valentin Gutknecht, added,

“We are delighted to have secured SWISS as our first airline partner.  Our new collaboration shows how even difficult-to-decarbonize sectors like air transport can help to scale up core climate technologies.  Pioneers like SWISS are playing a vital role in further developing our carbon removal technology and in enabling us to achieve our ambitious growth plans to permanently remove exponentially more tonnes of hard-to-avoid CO₂ emissions from the atmosphere every day.”

While flying brings people and cultures together, it also generates substantial emissions.  This is why the airline industry is taking action today, so future generations can also enjoy all the benefits that mobility brings.  SWISS is consistently pursuing initiatives to make their business and operations carbon-neutral by 2050.  Concrete measures range from deploying more efficient aircraft and using sustainable aviation fuel (SAF), to promoting pioneering new solutions that permanently remove carbon dioxide from the atmosphere.

SWISS is the world’s first airline to support the mineralization technology that neustark, an ETH Zurich spinoff, has developed.  The process takes carbon dioxide generated in biogas facilities and stores it in demolished concrete to permanently remove it from the atmosphere. SWISS’ partnership agreement with neustark will remain in effect until 2030, and includes options for enlarging the volumes covered and/or extending the agreement’s duration.
