A systematic review on the monitoring, reporting, and verification (MRV) of Carbon Dioxide Removal

Despite growing demand for carbon dioxide removal (CDR), there remains uncertainty around the integrity and quality of CO2 removal activities. Establishing robust monitoring, reporting, and verification (MRV) systems that support the veracity of CDR claims is essential to scaling investment and deployment. Yet, knowledge on MRV of CDR remains patchy and confusing. Synthesizing the latest science and highlighting gaps in technology development and research for measuring and accounting for CDR is essential to advancing the field and achieving overall CDR targets. In this presentation, we (1) highlight our approach for translating the MRV concept into a framework for evidence collection; and (2) provide preliminary results from our systematic review of the academic literature on MRV of eight different CDR methods. In doing so, we set the stage for ongoing and future evidence synthesis on MRV of CDR, a fundamental steppingstone for designing robust crediting frameworks and policies on CDR. This work is part of a larger community effort “Towards an Ecosystem of Systematic Reviews for Assessing the State of Knowledge in Carbon Dioxide Removal”.
