BG8.12 | Carbon removal, co-benefits, and risks of enhanced weathering from the field to the sea
Carbon removal, co-benefits, and risks of enhanced weathering from the field to the sea
Convener: Shashank Anand | Co-conveners: Salvatore Calabrese, Matteo Bertagni

Enhanced Weathering (EW) is a promising nature-based solution for atmospheric carbon removal, with estimates suggesting it has the potential to sequester gigatons of CO₂ per year. However, key uncertainties persist across the entire EW process, from the dissolution kinetics of silicate rock powder in soils to the transport and fate of weathering products in freshwater and marine environments. This session invites abstracts that address these uncertainties through theoretical, modeling, field studies, and experimental work. We particularly encourage cross-disciplinary contributions that explore not only the carbon sequestration potential of EW but also its co-benefits and environmental risks. By fostering collaboration across research disciplines and sectors, this session aims to advance a comprehensive understanding of EW, ensuring its scalable, safe, and effective role in global climate mitigation efforts.
