Audit Analysis
The Yaylabel 5.2 MW hydro project is a registered VCS avoidance project with a VVB-confirmed investment additionality test and no reversal risk, but it is undermined by a significant ERR discrepancy between the monitoring report (54,301 tCO2e) and the verification report (36,633 tCO2e), a 17.7% under-delivery relative to the ex-ante estimate, 29 corrective action requests during verification, and a grid emission factor drawn from 2008 data. The project is fundamentally sound in design but carries notable data-quality and documentation-consistency concerns.
Red Flags
- ERR contradiction: the monitoring report (Nov 2022) states 54,301 tCO2e while the verification report (Oct 2023) verifies only 36,633 tCO2e — a 32.5% gap that is not fully explained by the stated 17.7% under-delivery
- 29 Corrective Action Requests and 4 CLs were raised during verification, indicating pervasive data-quality and documentation errors in the monitoring report
- Grid emission factor of 0.543 tCO2/MWh is sourced from 2008 data, which is over 15 years old at the time of verification
- Baseline method is internally contradictory within the verification report itself (stated as both 'project' and 'jurisdictional')
- Multiple factual inconsistencies: installed capacity (5.2 MW vs 5.1 MWe), meter class (0.2S vs 0.5S), license date, and ERR values for 2010
