Carbon Dioxide Removal (CDR) methods, including those focused on marine environments, are currently being researched and piloted. They are seen as a means to address residual emissions and remove legacy carbon from the atmosphere once greenhouse gas emissions have been reduced, and to achieve the Paris Agreement's climate goals.
Monitoring, reporting and verification (MRV) is a structured process to collect, disclose and independently verify data on mCDR activities. The process includes quantifying CO2 removals, durability, uncertainties and environmental impacts. Going forwards, science-based guidance to develop these robust, transparent and scientific MRV frameworks for mCDR is needed.
The international working group of thirteen researchers has presented its findings and clear recommendations on the Monitoring, Verification and Reporting for mCDR activities. Under the leadership of Dr Helene Muri, Senior Researcher at NILU and Norwegian University of Science and Technology (NTNU), Norway, and Dr Olivier Sulpis at CEREGE - Aix-Marseille University, CNRS, IRD,
France, the team produced the report, which is being launched today by the EMB in a webinar.
The document emphasises, among other points, research knowledge gaps that present major challenges for the practical implementation and efficiency of mCDR methods in the Ocean. Among them are uncertainties about the processes and impacts, and the duration for which the carbon could be stored in the Ocean.
“No mCDR method currently has a sufficiently robust, comprehensive MRV in place,” says Helene Muri. “This means that efficient and safe deployment of mCDR methods cannot be ensured at the moment”.
Building the foundations for responsible development
The working group emphasises that investing in science and innovation, such as Ocean observations and modelling approaches and infrastructure, can help to advance the MRV field.
“If we would like to consider the use of mCDR, we have to invest in knowledge generation for MRV now,” says Helene Muri. “That will enable the development of fit-for-purpose MRV frameworks if or when we reach large-scale mCDR implementation.”
The researchers also call for the development of robust governance to underpin MRV for mCDR.
Helene Muri: “We do not currently have dedicated governance frameworks for MRV for mCDR”.
There is a need for a comprehensive, regulatory framework for MRV that will overcome the fragmentation, inconsistencies and lack of global governance of existing MRV systems.
