International Perspectives on Monitoring, Reporting and Verification for mCDR

 

Marine carbon dioxide removal (mCDR) approaches are increasingly considered; however, we are lacking a robust monitoring, reporting and verification (MRV) framework. For international acceptance of mCDR methods, it is essential to develop such frameworks with support of the broader international community. The authors undertake a step toward consolidation of MRV by establishing a global network of scientists organised into six "continental" nodes addressing the same set of MRV-related questions. The consultation shows that while there are many converging views on MRV (e.g. the importance of modelling for MRV), there are also differences in the regional MRV priorities (e.g. the importance of regional versus global models). Highlighting the areas of consensus and divergence in this study may be instrumental in the design of more widely accepted MRV frameworks.
