Marine carbon dioxide removal (CDR) has advanced significantly, with growing research activity, technological development, private-sector involvement, and movement toward field testing, but major questions remain about whether these approaches can remove carbon dioxide at meaningful scales, how that removal can be reliably measured and verified, potential environmental effects, and how marine CDR should be governed, says a new digital report from the National Academies of Sciences, Engineering, and Medicine.
Marine carbon dioxide removal (CDR) has advanced significantly, with growing research activity, technological development, private-sector involvement, and movement toward field testing, but major questions remain about whether these approaches can remove carbon dioxide at meaningful scales, how that removal can be reliably measured and verified, potential environmental effects, and how marine CDR should be governed, says a new digital report from the National Academies of Sciences, Engineering, and Medicine.
Part of a planned series, this report builds on a National Academies’ 2022 report, A Research Strategy for Ocean-Based Carbon Dioxide Removal and Sequestration, and is intended to provide an independent, peer-reviewed resource that can evolve as this fast-moving field develops. The 2026 update includes a new State of Marine CDR, 2026 module highlighting recent advances, emerging trends, and remaining knowledge gaps; an updated introduction and assessment framework; and updated and expanded modules on governance and social dimensions and ocean alkalinity enhancement. Periodic updates will be made as research and science progress and will be responsive to community needs and priorities.
