Soil Carbon Improvement Project through Grassland Management, in South Africa

Integrity

The validation report confirms additionality via a barriers test (validation report), and the project holds an 18% buffer pool which supports permanence. However, the project uses a project-specific baseline (method VM0026, baseline described as project) and there is no evidence the baseline has been recently reassessed. Leakage treatment is inconsistent across documents and not clearly applied in the most recent validation, which weakens the baseline/leakage integrity. Corrective actions (27 items and other requests listed in the monitoring report) further reduce confidence in robustness.

Transparency

Transparency is middling: the VVB (4K Earth Science) is named and a monitoring period is provided (monitoring report, 2018-07-01 — 2022-12-31). The monitoring report is recent (2025-09-20). However, key numeric outcomes—total removals/ERR claimed and verified—are not stated in the extracted record, and usage/monitoring methods for activity rates are not provided, which limits external verification.

Claim Safety

Claim safety is moderate-to-low. The project uses a project-specific baseline which raises over-crediting risk compared with jurisdictional baselines. Leakage justification is contradictory (earlier validation said leakage was deemed negligible; the later validation/monitoring materials state leakage is not addressed), increasing uncertainty about potential leakage and credits issued. CORSIA eligibility is false, which reduces one double-claim risk, but CCP status is not stated.

Documentation

Documentation coverage is adequate in quantity (9 documents referenced, including PDD, validation and monitoring reports) and extraction confidence is high. The monitoring report is recent (2025-09-20). Nevertheless, there are many corrective actions and clarification requests outstanding from the verification process, and several important fields remain unreported in the extracted record, indicating incomplete or unresolved documentation issues.

Overall

I privileged the most recent and specific documents where contradictions occurred: when validation/monitoring documents conflicted with older PDD entries I favored the validation or monitoring report dated 2025 (monitoring report 2025-09-20; validation report 2025-09-22) because they are later and directly address implementation. Specific contradictions addressed: reversal events — privileged 'none reported' from validation report (2025-09-22) over the earlier 'not addressed' (2024-05-14); leakage justification — privileged the 2025 validation statement that leakage is not addressed over the 2024 statement that leakage was deemed negligible; safeguards, grievance mechanism, benefit sharing and FPIC — privileged monitoring report (2025-09-20) reporting these as present over unknown/absent earlier entries; additionality test — privileged the validation report (2024-05-14) barrier test over an earlier PDD investment test because the validator's assessment is the authoritative check; crediting period — privileged the monitoring report 2018–2038 (2025) over the PDD 2017–2047 since monitoring provides current operational dates. Those contradictions, plus 27 corrective actions and missing ERR figures, reduced scores for integrity, claim safety and documentation.
