Audit Analysis

The Mt Kenya Biochar Project demonstrates a verified additionality assessment and a strong over-delivery relative to its lifetime estimate (approximately 3.8× the pro-rata expectation for the first monitoring period), which is reassuring for claim safety. However, the verification report identified six material findings and required nine corrective actions spanning moisture data, biochar yields, transportation, energy use, and end-use dates, indicating significant initial data-quality weaknesses. Key gaps remain in permanence safeguards (no buffer pool stated), leakage treatment, and free, prior and informed consent.

Red Flags

  • Nine corrective action requests were raised by the VVB covering moisture content errors, biochar yield outliers, transportation distances, electricity/diesel/LPG consumption, wood vinegar disposal emissions, and eligible end-use dates — indicating the initial monitoring submission had widespread data-quality problems
  • Free, prior and informed consent (FPIC) was not conducted, a significant safeguard gap for a biochar project operating in a Kenyan community context
  • No buffer pool percentage is stated in the available documents, leaving permanence risk unquantified for a biochar project where long-term carbon stability is the core claim
  • Leakage is neither quantified nor justified in the extracted record, despite biochar production displacing biomass that could have been used for other purposes
