Audit Analysis

The Chi Khe Hydropower Project is a straightforward small-hydro CDM project with a jurisdictional baseline, VVB-confirmed investment additionality, and no reversal risk inherent to the technology. The main concerns are a contradiction in how leakage is justified across documents, three material findings with one open corrective action, and the absence of any stated CORSIA or CCP eligibility. Overall the project is low-risk but documentation gaps and the unresolved leakage inconsistency prevent a higher rating.

Red Flags

  • Leakage justification is contradictory: the monitoring report (2022) states leakage was 'quantified' while the validation report (same date) states it was 'deemed negligible' — both supporting a 0% deduction, but the basis is inconsistent.
  • Three material findings were raised by the VVB (compliance clarification, APJ monitoring documentation, GWP values for post-2020), with one corrective action still open.
  • No buffer pool, permanence mechanism, or reversal-risk mitigation is documented, though this is less critical for a hydro project.
  • CORSIA eligibility and CCP status are not stated in any available document, leaving dual-channel risk unassessed.
