This document discusses MRV (Measurement, Reporting and Verification) systems for soil organic carbon and soil carbon sequestration. It provides an overview of where current MRV systems and guidance are, including the IPCC guidelines, and what is still missing to fully utilize soils in climate mitigation efforts. Specifically, it notes that a clear signal of support from policymakers could help scale up investments in research, pilot projects and adoption of soil health practices. The unique opportunity presented by the Koronivia Joint Work on Agriculture to provide such a conclusion at COP could be a game-changer for soils to be fully considered in NDCs.
