Abstract

The sustainable development goals (SDGs) provide a comprehensive global plan of action for peace and prosperity for people and the planet. These ambitious SDG commitments require many actions to achieve and it is important that potential new activities, such as ocean-based carbon dioxide removal (CDR) as a means of climate change mitigation, do not hinder progress towards the SDGs. Here we describe a CDR SDG assessment framework that we 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.
