Strategies for the Evaluation and Assessment of Ocean based Carbon Dioxide Removal (SEAO2-CDR)

Carbon dioxide removal is a fundamental tool in combatting climate change. SEAO2-CDR aims to establish and evaluate the mechanisms and processes required to ensure the environmentally safe, socially acceptable and economically viable implementation of appropriate ocean-based carbon dioxide removal (CDR) approaches in support of global climate policies. It will achieve this by developing the tools and frameworks that facilitate the evaluation and application of archetypal biological, chemical and physical ocean-based CDR techniques. Common assessment processes, governance structures and technologies will be used to explore system-level interactions between different approaches in order to deliver the insights, tools and guidelines required for the safe and effective implementation of ocean-based CDR. These advances will enable SEAO2-CDR to help establish the extent to which such approaches can support climate change mitigation and adaptation strategies and the transition to a climate-neutral and resilient society.
