Soil carbon sequestration offers a massive opportunity for climate mitigation, but measuring it accurately remains difficult. Factors like soil heterogeneity, fluctuating densities, and the high cost of physical sampling create significant gaps in verification for carbon markets. New EU initiatives and projects like MRV4SOC are developing process-based models to combine field data with remote sensing. These efforts aim to create a cost-effective certification framework for carbon farming while addressing risks like carbon reversal from extreme weather.
