SEAO2-CDR will enhance the technical viability of ocean-based CDR by characterising the key system boundaries, processes, material and energy flows of different approaches, and establishing their temporal and spatial monitoring requirements and mechanisms.

It will also develop the social, regulatory, political, economic and ethical frameworks required to facilitate and support OCDR uptake at scale. Finally, it will provide a deep understanding of realistic implementation policies and pathways via an integrated assessment of system-level effects.

The specific objectives of SEAO2-CDR are:

O1.To enhance our understanding of emerging OCDR approaches by characterising their potential operational space using common frameworks for life cycle assessments (LCA) and techno-economic assessments (TEA). [WP2]
O2.To develop, assess and harmonise technological solutions for OCDR monitoring reporting and verification. [WP3]
O3.To improve understanding of public and stakeholder perceptions by exploring the societal acceptance of OCDR in the context of the broader ecosystem services offered by different approaches. [WP4]
O4.To derive a scientifically grounded and stakeholder oriented multidimensional governance framework for OCDR that considers the legal, ethical, policy and geopolitical implications of upscaling OCDR approaches. [WP5]
O5.To develop the commercial frameworks and incentivisation strategies needed to support the potential for OCDR operationalisation, including via improved abatement cost estimates and standardised carbon accounting. [WP6]
O6.To support assessment of the ecological and economic feasibility of OCDR deployment on a regional scale through the improved representation of OCDR approaches in Integrated Assessment Models (IAMs). [WP7]
O7.To generate the roadmaps required to help policy makers bring OCDR to scale. [WP8]
