Audit Analysis

A straightforward small hydropower project under CDM using the standard AMS-I.D methodology with a jurisdictional grid baseline. The project shows no over-crediting (claimed and verified ERRs are identical at 90,230 tCO₂e) and no reversal or leakage concerns, but key additionality details and monitoring-period data were not captured in the extracted record, limiting confidence in the full MRV chain.

Red Flags

  • Additionality test type and VVB confirmation are not stated in the extracted record, leaving a gap in verifying a core CDM requirement
  • No monitoring report appears in the evidence document list, and the monitoring period is not stated, making it impossible to confirm periodic MRV compliance
  • A contradiction exists between the validation report (leakage deemed negligible) and an undated appendix (leakage not addressed), indicating inconsistent documentation
