Audit Analysis
The Veolia Antanas landfill gas project has VVB-confirmed additionality and a conservative verified-to-claimed ratio, but is undermined by repeated calibration deficiencies flagged by ICONTEC, a project-specific modeled baseline with no buffer pool, and contradictory leakage justifications within the same verification report. The project delivered only about 14% of its pro-rata lifetime expectation for the monitoring period, suggesting the ex-ante baseline may be overstated.
Red Flags
- Multiple calibration certificates and procedures were missing or non-compliant during the monitoring period (CAR01–CAR03, CL01), requiring conservative error deductions and corrective actions before issuance
- Leakage justification is internally contradictory within the verification report: stated as 'deemed negligible' in one passage and 'quantified' in another, with a 0% deduction applied
- Free, Prior and Informed Consent (FPIC) was not conducted, and no grievance mechanism is documented
- Crediting period is inconsistent between the validation report (20 years, 2020–2040) and the verification report (7 years, 2017–2024)
