UNDO is a carbon dioxide removal company specializing in enhanced weathering, a nature-based technology permanently locking away CO₂. Rock weathering has naturally removed billions of tons of CO₂ over Earth's history. UNDO accelerates this process by spreading crushed rock with a high reactive surface area onto agricultural land, speeding up the weathering process. Carbonic acid created from rain and soil moisture combining with CO₂ breaks down the rock, releasing mineral nutrients and crystallizing CO₂ into carbonate. In addition to permanent, rapid, and scalable carbon removals, UNDO’s model delivers significant co-benefits including improved soil health, ocean deacidification, and economic opportunity for farming communities.
