Why us?
What are we offering?
We remove CO₂ where it matters most and turn the tide for a liveable future
We are the Planeteers, a climate-tech startup from Hamburg, Germany. We capture CO₂ in water and unleash the potential of the oceans as the largest carbon sink on our planet. Accelerated Weathering of Limestone (AWL) is a reaction in which CO₂ is „neutralized“ using limestone. This reaction occurs in nature all the time, everywhere and on a large scale. Time scales of natural limestone weathering are thousands of years. With our technology, the process can be extremely accelerated, so that large amounts of CO₂ can be rendered „harmless“ within minutes.
