A standing committee of the National Academies of Sciences, Engineering, and Medicine will address the following needs of the marine carbon dioxide removal (mCDR) community:

• Creation of a digital, online version of the National Academies’ 2022 report, A Research Strategy for Ocean-Based Carbon Dioxide Removal that can be revised and published with peer-reviewed updates as warranted to ensure that the 2022 report remains relevant and serves as a trusted, vetted, and transparent resource for the wide range of stakeholders comprising the mCDR community. Updates could include:

o Inclusion of an annual or semi-annual “state of the science, technology, and research” update, summarizing the landscape of the rapidly advancing field of mCDR.

o Updates of fundamental understanding and specific research and development needs of any marine CDR approach. This would include updating independent modules of the report and updating the summary tables of feasibility for the various marine CDR approaches as new information on potential, scalability, environmental impacts, cost, and other factors becomes available.

o Updates of overarching research and development needs of cross-cutting mCDR research (not approach-specific) such as legal and regulatory issues, social dimensions and environmental justice considerations, and monitoring, reporting, and verification. This could include additions such as consensus on a code of conduct for conducting mCDR research in a responsible and transparent manner or specific recommendations for monitoring, reporting, and verification (MRV) of atmospheric carbon dioxide removed (including data transparency), and prioritization of mCDR approaches.

o Additional information not fully covered in the original report, such as the consideration of environmental impacts on deep-sea ecosystems, assessment of new or co-located approaches, or ad hoc peer review of reports or projects completed outside the National Academies.

• Initiation of new studies or new components to the digital mCDR report
