Enhanced Weathering (EW)—the application of crushed silicate rocks to soils and terrestrial waters—has emerged as a promising nature-based solution for atmospheric carbon removal, with estimates suggesting the potential of gigatons of CO₂ removal annually. Yet, significant uncertainties remain around EW, from dissolution kinetics in soils to the transport, transformation, and fate of weathering products in soil and freshwater systems.
This session invites contributions that tackle these uncertainties through theoretical and observational approaches. We particularly encourage cross-disciplinary work that explores not only the carbon removal potential of EW, but also its environmental co-benefits, possible risks, and applications in under-studied regions. By bringing together diverse perspectives, the session seeks to advance a more comprehensive understanding of EW and its role in achieving scalable and safe climate mitigation.
