The NASEM report – Assessment of the feasibility, potential impacts, and benefits of marine CDR methods as well as recommending a U.S. research program

Andreas Oschlies is a member of the expert committee of the NASEM-Report “A Research Strategy for Ocean-based Carbon Dioxide Removal and Sequestration

This report builds on previous work from the National Academies to assess what is currently known about the benefits, risks, and potential for responsible scale-up of six specific ocean-based CDR strategies (OAE, nutrient fertilization, artificial up- & downwelling, seaweed cultivation, ecosystem recovery, electrochemical engineering approaches) as identified by the sponsor of the study, ClimateWorks Foundation. It describes the research needed to advance understanding of those approaches and address knowledge gaps. The resulting research agenda is meant to provide an improved and unbiased knowledge base for the public, stakeholders, and policymakers to make informed decisions on the next steps for ocean CDR, as part of a larger climate mitigation strategy; it is not meant to lock in or advocate for any particular approach.
