Enhanced rock weathering (ERW) is a carbon dioxide removal (CDR) strategy that converts atmospheric CO2 to stable carbonates by applying minerals to agricultural land. This Perspective discusses the potential difficulties in scaling ERW, covering feedstock availability, impacts on soil–plant systems, uncertainties around CDR efficiency along the land–ocean continuum and socio-economic challenges.
