Ocean-Based Carbon Dioxide Removal Options and Governance

After entry into the Paris Agreement, it has become obvious that aggressive emission reduction initiatives and large-scale deployment of carbon dioxide removal are needed to avoid passing critical climatic thresholds. While early research of carbon dioxide removal options focused on terrestrial approaches, there has been increasing attention to the potential role of the world’s oceans.

However, large-scale deployment of such options pose potentially substantial risks to marine environments and key economic stakeholders. Moreover, there is likely to be substantial public backlash to research absent the existence of a sound regulatory framework for risk assessment, monitoring, and public deliberation.

This presentation will cover the potential risks and benefits presented by different ocean-based geoengineering options. It will include a discussion of regulatory efforts to date by international treaty regimes, and other potentially pertinent regimes, including those with a marine regulatory focus, as well as the potential role of the UNFCCC/Paris Agreement.
