Audit Analysis
The Nkongsamba biochar project in Cameroon was verified by EnergyLink Services with no material findings, and the 184 tCO2e claimed matches the verified figure exactly. However, critical integrity elements — additionality testing, baseline methodology, buffer pool, and leakage treatment — are absent from the extracted record, creating significant uncertainty around the robustness of a 100-year permanence claim. The project is best understood as a verified but under-documented removal credit with meaningful gaps in its environmental integrity case.
Red Flags
- 100-year permanence claim with no buffer pool or reversal-risk mitigation documented in the verification report
- No additionality test type or VVB confirmation of additionality found in any available document
- No baseline methodology or baseline reassessment date stated, leaving the counterfactual unanchored
- No leakage deduction or justification provided for a biochar project where feedstock-sourcing and production leakage are expected
- Safeguards, FPIC, and grievance mechanism all absent from the extracted record
