The authors analyze the role of EW under cost-effective mitigation pathways, by including the CDR potential of basalt applications from silicate weathering (geochemical CDR) and enhanced ecosystem growth and carbon storage in response to phosphorus released by basalt (biotic CDR). Using an integrated carbon cycle, climate and energy system model, they show that the application of basalt to forests could triple the level of carbon sequestration induced by EW compared to an application restricted to croplands.
