Climeworks empowers people to fight climate change by permanently removing CO₂ from the air with direct air capture technology. We are dedicated to purpose, we are disruptive thinkers, and we are one team.
We develop, build and operate direct air capture (DAC) machines, which capture CO₂ directly from the air. The air-captured carbon dioxide can either be recycled and reused as a raw material or completely removed from the air by safely storing it underground, permanently.
Founded in 2009 by engineers, Christoph Gebald and Jan Wurzbacher, Climeworks was built with the vision to inspire 1 billion people to remove CO₂ from the air, and is now the leader in technological carbon removal.
We are featured as a&nbsp;<a href="https://climeworks.com/news/climeworks-named-one-of-time100-most-influential-companies" data-nuxt-link="">TIME100 Influential Company 2022</a>&nbsp;and&nbsp;<a href="https://climeworks.com/news/climeworks-is-selected-for-2022-global-cleantech-100" data-nuxt-link="">Global Cleantech 100 Company 2022</a>&nbsp;and drive a revolutionary technology engineered to solve the most pressing issue of our time.
