Klimate

We are devoted to accelerating the development and adoption of technologies that can help fight climate change by actively removing CO2 from the atmosphere. The challenge We are emitting 50 Gigatons of CO2 every year, and that needs to be reduced by at least 80%. However, that still leaves 10 Gigatons of CO2, and we need to get all the way to zero. Trees are great, but we need many more solutions as well if we are to get to zero. Currently, most of these are way too expensive (and limited in capacity) for companies to use. We've developed a platform that combines methods and makes it available to every company that wants to compensate their emissions. We work with cutting edge technologies, including Direct Air Capture, Bio char, Bio oil etc.
