BG8.10 | Enhanced Rock Weathering and Inland Water Alkalinity Enhancement for Carbon Dioxide Removal
Enhanced Rock Weathering and Inland Water Alkalinity Enhancement for Carbon Dioxide Removal
In addition to rapid emission reductions, swift and large-scale carbon dioxide removal (CDR) is needed to reduce the risks of severe climate change. Multiple CDR approaches will be needed to deliver the targeted amounts of 10s of Gt CO2 yr-1. This session solicits multidisciplinary and novel contributions of research on two CDR approaches: enhanced rock weathering (ERW) and inland water alkalinity enhancement (IWAE), including: 1) technical aspects, 2) ecosystem impacts, both negative and positive, 3) best practices, 4) community engagement, 5) techno-economic and life cycle aspects, and 6) monitoring, reporting and verification approaches. Both ERW and IWAE aim to drawdown CO2 and convert it to bicarbonate for eventual delivery to oceans via rivers for long-term storage. This session thus aims to inform decision making on how and whether ERW and IWAE can be used to help us reach our climate targets.
