what we do

Climeworks captures CO2 from air with the world’s first commercial carbon removal technology. Our direct air capture plants remove CO2 from the atmosphere to supply to customers and to unlock a negative emissions future.



Climeworks was founded by engineers Christoph Gebald and Jan Wurzbacher, who decided to build a company together on the day they met at university in 2003.


Jan and Christoph commenced research on direct air capture in their masters studies at the Professorship of Renewable Energy Carriers at ETH Zürich.


The first system concepts and working prototypes were developed in the laboratories of ETH Zürich.

Climeworks was established.


Climeworks closed its first financing round, providing for the construction of a first demonstration prototype, scaled-up by a factor 1’000 compared to the previous laboratory technology.


Audi becomes a customer and key partner. The car manufacturer uses Climeworks products for the production of renewable fuels from atmospheric CO2.


We developed the concept of the modular CO2 Collector as well as a working prototype.


We built the production infrastructure with a capacity of more than hundred CO2 collectors per year.

Climeworks announces participation in three leading European CO2 conversion projects (Kopernikus Power-to-X, STORE&GO, Celbicon).

Climeworks is chosen as one of 20 companies to present its technology as a potential solution to meeting climate targets at the COP22 UN Climate Change Conference 2016 in Marrakech.


Climeworks commissions the world’s first commercial-scale direct air capture plant.


Climeworks has assembled the largest team of experts in the field which is led by our founders, executive board and board of directors:

Climeworks is Climeworks not because of its offices, machines or patents, but primarily because of its people.


Direct air capture is a disruptive approach for mitigating the increasing CO2 concentration in the atmosphere. Industrialising direct air capture technology in turn requires disruptive engineering approaches.


Climeworks is among the only scalable solutions to remove CO2 from the air without unintended consequences.
