The ReSCUE Oceans Act establishes a comprehensive federal program to research, develop, and monitor marine carbon dioxide removal technologies as a climate solution. The bill directs NASA to use satellites to track ocean-based carbon removal activities, requires the Commerce Department to create a research program within 90 days to study six specific marine carbon removal approaches (such as ocean alkalinity enhancement and macroalgae cultivation), and authorizes competitive grants to universities, governments, tribal nations, and research consortiums to conduct field trials. The legislation creates a governance framework with designated federal research areas, five-year permits with mandatory environmental monitoring and community oversight, and establishes an interagency working group to coordinate efforts and develop standards for measuring carbon removal credits. Key protections include public access to non-proprietary research data, respect for tribal data sovereignty, community benefit-sharing arrangements, and funding authorized through fiscal year 2031, with at least $10,000 reserved for engagement with Indian Tribes and Native Hawaiian organizations.
