Methodology
SOC MRV — State of the Art
State-of-the-art SOC MRV pairs strategic ground-truth sampling with satellite remote sensing and Tier 3 process modelling that assimilates Earth-observation data. Well-designed programmes target ≤±15% uncertainty on stock change with annual verification. In parallel, the ICVCM approved the first sustainable-agriculture methodologies against its Core Carbon Principles, raising the integrity bar for the whole market.
What state-of-the-art MRV looks like
The best programmes no longer rely on sampling alone. They fuse a designed network of ground samples with satellite remote sensing and Tier 3 process models that assimilate Earth-observation data — cutting cost while keeping estimates anchored in measurement.
Satellite remote sensing + ground-truth
Earth observation extends coverage across fields and time, while strategic ground samples keep it honest and calibrated.
Tier 3 modelling with EO data assimilation
Process models ingest satellite data to estimate stock change at scale with site-specific fidelity.
≤±15% uncertainty
Leading MRV targets ≤±15% uncertainty on stock-change estimates, with verification typically annual.
ICVCM CCP approval
The first sustainable-agriculture methodologies were approved against the Core Carbon Principles, raising the integrity bar market-wide.
Estimates, not guarantees. Uncertainty targets and regulatory milestones are stated as of July 2026 and are site- and standard-specific. Always verify current data and rules before acting.
Frequently asked questions
How is soil carbon measured at scale today?+
By combining a designed network of ground samples with satellite remote sensing and Tier 3 models that assimilate EO data — reducing cost while keeping estimates grounded in measurement.
What uncertainty should credible SOC MRV achieve?+
Leading programmes target ≤±15% uncertainty on stock-change estimates, with verification typically annual. Achievable uncertainty is site-specific — treat any figure as an estimate to confirm.
What did ICVCM's CCP approval change?+
The approval of the first sustainable-agriculture methodologies against the Core Carbon Principles gives buyers a clearer integrity benchmark for soil-related credits.
