Guizhou Wujiang Siling Hydropower Project

Audit Analysis

The Guizhou Wujiang Siling Hydropower Project is a CDM-registered small hydro scheme with VVB-confirmed additionality and a specific grid emission factor, but it is undermined by two corrective action requests (including a measurement procedure inconsistency with the approved methodology), contradictory baseline and leakage characterisations across documents, and a 0% leakage deduction whose justification shifts between 'quantified' and 'deemed negligible' depending on which report is read. The project delivered exactly the claimed emissions reductions in its first monitoring period, but the absence of a buffer pool, missing safeguards documentation, and several unresolved data gaps limit confidence in the credit quality.

Project Description

Red Flags

• ⚠Corrective Action Request: the measurement procedure for EGfacility,y is inconsistent with ACM0002 v13.0.0, raising doubt about the accuracy of verified emissions reductions
• ⚠Leakage deduction is 0% yet the justification is contradictory — the validation report (2012) calls it 'deemed negligible' while the monitoring report (2013) labels it 'quantified', leaving unclear whether any quantitative assessment was actually performed
• ⚠Baseline method is described as 'project-specific' in the monitoring report but 'jurisdictional' in the PDD, creating ambiguity about which grid emission factor basis was applied
