Enhanced rock weathering (ERW) is a promising scalable and cost-effective carbon dioxide removal (CDR) strategy with significant environmental and agronomic co-benefits. A major barrier to large-scale implementation of ERW is a robust monitoring, reporting, and verification (MRV) framework. Here, the authors outline a mass-balance-based method in which analysis of the chemical composition of soil samples is used to track in situ silicate rock weathering.
