Report: Report on a sustainable development goals framework for ocean-based NET evaluation

David P. Keller and Wilfried Rickels, GEOMAR, January 2024

This report describes a CDR SDG assessment framework that was developed for future use in evaluating the sustainability of different ocean-based CDR options or portfolios. The assessment methodology describes how the user should first collect relevant information about the CDR approach(es) and then match it to the corresponding SDG indicators or sub-indicators. After that the user must transform (normalize) the derived indicator data for comparability. Then, the user must follow several steps of weighting, aggregation, and evaluation that follow an SDG structured nesting approach. In the end the methodology allows the user to quantify CDR impacts on progress towards attaining overall “sustainability”. No application of the framework was done as part of this task, but should be done in future research endeavors.
