Undo is a world-leading carbon dioxide removal project developer specialising in enhanced rock weathering. Enhanced weathering is a nature-based technology that permanently locks away CO₂ from the atmosphere. The geological process of weathering has happened naturally for millions of years, removing billions of tonnes of CO₂ over Earth's history. Undo accelerates this natural process by spreading crushed silicate rock with a high reactive surface area onto agricultural land, where plants and microbes in the soil speed up the weathering process. The breakdown of the rock by CO₂ dissolved in rainwater releases nutrients and bicarbonates, which end up in the oceans as solid carbonate minerals, permanently removing CO₂. Part of Microsoft and Stripe’s carbon portfolios, Undo is scaling operations in the UK, Australia, and Canada. The rock, a by-product of the aggregate and mining industry, is given to local farmers for free and spread on agricultural land using existing infrastructure.
