Forest Conservation in Boumba-et-Ngoko
Score Breakdown
Integrity
verified Additionality was confirmed by the VVB through an investment test in the 2024 verification report.
missing Baseline reassessment timing is not stated, and the project-specific baseline approach is less robust than a recent standardized reassessment.
Transparency
verified The project has a named verifier, Earthood Services Private Limited, and a defined monitoring period from 2022-01-01 to 2023-12-31.
missing Key MRV fields are missing from the extracted record, including verified versus claimed emissions reductions and the usage monitoring method.
Claim Safety
verified The latest verification report states a 20% leakage deduction and no reported reversals, which helps reduce over-crediting risk.
missing The project uses a project-specific baseline and the contradiction on leakage justification weakens confidence in the claimed climate benefit.
Documentation
verified Seventeen documents were used and the latest verification report is dated 2024-12-19, which is reasonably recent.
missing Extraction confidence is only medium, and several important fields are not stated in the available documents, including issuance totals and usage-rate evidence.
Detailed Analysis
Integrity
The 2024 verification report by Earthood Services Private Limited confirms additionality through an investment test, which is a meaningful positive for integrity. The report also shows a 24% buffer pool and states that no reversal events were reported, while leakage is deducted at 20%, which supports permanence and leakage management. That said, the baseline is project-specific and the record does not state when it was last reassessed, so baseline robustness is only moderate.
Transparency
Transparency is limited by missing MRV detail in the extracted record. The monitoring period is clearly stated and the verifier is named, but verified versus claimed ERR totals are not found, and the usage monitoring method is also not stated. The absence of these core reporting elements reduces the ability to independently assess performance.
Claim Safety
Claim safety is moderate rather than strong because the project has some safeguards against over-crediting, including a 20% leakage deduction in the latest report and no reported reversals. However, the baseline remains project-specific, and the contradiction over leakage treatment between documents weakens confidence in the final accounting. CORSIA eligibility and CCP status are not stated, so dual-market claim risk cannot be ruled out from the extracted record.
Documentation
Documentation quality is middling. Seventeen documents were used and the latest verification report is recent, but extraction confidence is only medium, indicating at least one key source was not fully readable. Several important items are missing from the available record, including verified emissions reduction totals, usage-rate evidence, and baseline reassessment timing.
Overall
I privileged the most recent verification report dated 2024-12-19 when resolving contradictions, because it is the latest and most authoritative document in the extracted set. On that basis, I treated the 24% buffer pool, the 20% leakage deduction, and the statement that no reversals were reported as the controlling values, while noting that earlier documents conflict on each of those points. Those contradictions materially reduce reliability, but the project still shows a credible additionality claim and some permanence safeguards, keeping the overall score in the moderate range.
Audit Analysis
This is a registered VCS forest conservation project with a VVB-confirmed investment test, a sizeable buffer pool, and no reported reversals, which supports moderate integrity. However, the record has important evidence gaps around monitoring detail, credit issuance figures, and baseline reassessment, and there are contradictions on buffer pool size, leakage treatment, and reversal reporting that reduce confidence.
Project Description
Proponent: CarbonSinkGroup S.R.L. Protocol categories: Agriculture Forestry and Other Land Use Protocols: VM0010 Estimated annual GHG reductions: 362095 tCO2e Region: Africa Registration date: 2023-07-18
Red Flags
- The buffer pool is inconsistent across documents, with 24% in the 2024 verification report versus 10% in an earlier document.
- Leakage treatment is inconsistent: the latest report says leakage is deemed negligible, while an earlier document says it was quantified.
- Reversal handling is not fully consistent, with the latest report saying no reversals reported and an earlier document saying reversals were not addressed.

Cosa migliorerebbe questo punteggio
- Publish the verified versus claimed emissions reduction totals, along with the underlying monitoring calculations and usage monitoring method.
- Resolve the document inconsistencies on buffer pool size, leakage treatment, and reversal handling, and state when the baseline was last reassessed.
Questi suggerimenti indicano quali prove pubbliche aggiuntive potrebbero migliorare il livello di confidenza di questa valutazione. Non garantiscono un punteggio futuro più alto.
