Rethinking CO2 Removal Efficiency in Enhanced Rock Weathering

Figure 1. Difference among CO₂ sequestration in natural process of silicate rock weathering (a), ERW process (b) and original soil (c). C.L. and S.K. drafted the viewpoint. Y.G. made the figure. All authors contributed ideas and edits to the viewpoint. Dr. Chaoliu Li is a research scientist in the Department of Earth & Planetary Sciences at Yale University and a member of the Yale Center for Natural Carbon Capture. His research focuses on environmental chemistry and the carbon cycle in the Himalayas and Tibetan Plateau, with particular emphasis on identifying the sources of black carbon using carbon isotope compositions (Δ¹⁴C and δ¹³C). He is currently investigating the mechanisms and impacts of enhanced rock weathering as a strategy for removing carbon dioxide from the atmosphere. His published work has been cited approximately 5,000 times. Dr. Shichang Kang is the director of the Institute of Mountain Hazards and Environment (IMHE), Chinese Academy of Sciences (CAS), and a professor of University of Chinese Academy of Sciences (UCAS). Dr. Kang mainly focuses on climate and cryospheric changes, environmental chemistry of snow/ice and atmosphere, paleoclimate and environmental variability recovered by ice core records in the Tibetan Plateau. He has published more than 700 peer-reviewed papers in international journals with a citation more than 40000 (Google Scholar and H = 96). He is Editor-in-Chief of Journal of Glaciology and Geocryology. He has been a PI or co-PIs for more than 40 projects and organized more than 40 field expeditions in the extreme high elevations of the Tibetan Plateau, such as Mt. Everest, as well as Antarctic and Arctic. C.L. and S.K. were supported by the Gansu Provincial Science and Technology Program (23ZDFA017).
