Audit Analysis

A CDM hydropower project in Sichuan, China, with VVB-confirmed additionality via an investment test, but the validation report raised four corrective action requests specifically targeting the quality of the investment-cost analysis and the transparency of the common-practice comparison. The absence of any verified emission-reduction figures, monitoring-period data, or post-validation reports leaves the actual delivery of the 482,122 tCO₂e claim unconfirmed, and a significant discrepancy in the grid emission factor between the validation report and an appendix undermines confidence in the baseline calculation.

Red Flags

  • Grid emission factor discrepancy: the validation report (2012-09-11) uses 0.7707 tCO₂/MWh while an appendix document lists 1.087 tCO₂/MWh — a 41% difference that materially affects the claimed 482,122 tCO₂e
  • Four corrective action requests in the validation report question the sufficiency of investment-cost inputs and the transparency of the common-practice project selection, yet no monitoring or verification reports were found to confirm these were resolved
  • No verified emission-reduction figures, monitoring period, or verification reports exist in the extracted record, so the claimed ERR cannot be independently confirmed
  • Low extraction confidence across the document set, with one document of unknown type, limits the reliability of the available evidence

Risk Indicators

Additionality

VVB-confirmed but CARs question cost inputs and common-practice transparency

Permanence

Avoidance project (grid displacement); no reversal risk identified

Leakage

0% deduction, reasonable for grid-connected hydro

Baseline

Project-specific baseline; no reassessment date recorded

Safeguards

Safeguards mentioned; no FPIC or grievance mechanism documented

Double-claim

CORSIA and CCP status not stated in available documents
