Audit Analysis
A registered VCS coal-mine-methane power generation project with VVB-confirmed additionality and a reasonable 0% leakage deduction for a combustion-based activity. The verified ERR matches the monitoring-period ex-ante estimate, and all material findings were closed. However, the project-specific baseline, several missing MRV details, and unresolved contradictions across documents temper confidence in the overall credit quality.
Red Flags
- Contradiction on whether methane capture is legally required (PDD says yes, validation report says no) — if capture is mandated, additionality is materially weakened
- Five material findings during validation/verification including use of outdated IPCC emission-factor guidelines and a missing IRR spreadsheet, all closed but indicating initial documentation quality gaps
- CORSIA eligibility and CCP status are not stated in any available document, leaving dual-channel risk unassessed
Credit Vintages
No issuances recorded on the registry.
Risk Indicators
VVB-confirmed investment test
Combustion project, no storage, reversal N/A
0% deduction, negligible for on-site combustion
Project-specific, measured; not yet due for reassessment
FPIC, grievance mechanism, safeguards documented
CORSIA and CCP status not stated
