UNDO is a pioneering nature-based carbon removal company with an ambition to remove over one billion tonnes of atmospheric CO₂. Since 2022, UNDO has worked at the cutting edge of science to develop its enhanced rock weathering (ERW) technology, which draws down CO₂ and boosts soil health, generating permanent, high-quality carbon removal with added co-benefits. With customers such as British Airways, Microsoft and McLaren Racing, UNDO is establishing a range of commercial partnerships that will enable the spreading of millions of tonnes of rock each year, a first step towards billion-tonne scale operations. UNDO built its own tech platform, has world-leading scientific R&D, and has written the partnership playbook to harness global networks on scaling carbon removal globally. The global ERW company has spread more crushed silicate rock than any other ERW developer and uses its operational, scientific, and commercial knowledge to drive down the cost of high-quality carbon removal. Critically, UNDO’s patent pending measurement, reporting, and verification process encompasses a multi-proxy approach across solid, aqueous, and gaseous measurements combined with a best-in-class geochemical model.
