Terrestrial enhanced weathering (EW) on agricultural lands is a proposed carbon dioxide removal (CDR) technology involving the amendment of soils with crushed base cation-rich rocks, such as basalt. Over a quarter of a billion dollars have been raised by commercial EW start-ups across the globe, accelerating the deployment of EW at scale. In this Review, the authors outline the scientific knowledge and policy requirements for scaling EW.
