Recent advances to enhanced rock weathering as a carbon dioxide removal strategy: assessing future risks and opportunities
Convener: Amanda Stubbs | Co-conveners: Mike Kelland, Xinran Liu, Christiana Amalie Dietzen, Tom Reershemius

By mid-century, the removal of several billion tonnes of CO2 annually will be required to meet the 1.5 °C target set by the Paris Agreement. This necessity underscores the importance of large-scale implementation of negative emission technologies (NETs) for carbon dioxide removal (CDR). As enhanced rock weathering (ERW) operations expand globally, the improved understanding of relevant mechanistic processes and the development of robust methods for MRV is crucial for achieving our climate goals. This session invites innovative research contributions on ERW, including: 1) recent developments in monitoring, reporting, and verification methods; 2) environmental and ecological impacts; 3) public engagement and perception; 4) strategies for scaling up ERW; 5) economic assessments; and 6) identification of knowledge gaps in the field. The session aims to showcase the latest research on technological innovations, practical applications, and limitations of ERW, while fostering cross-disciplinary collaboration to enhance its effectiveness as a CDR strategy for climate change mitigation.
