Audit Analysis
A CDM biogas-recovery and CHP project at the West Tehran Wastewater Treatment Plant with VVB-confirmed additionality via an investment test, but a project-specific modeled baseline, a 0% leakage deduction justified only as 'deemed negligible' (contradicted by an appendix suggesting quantification), and a validation report that flagged 16 material findings (8 CLs, 8 CARs) before resolution. No monitoring-period data, FNRB method, or usage-rate figures were found in the extracted record, limiting the ability to verify actual delivery against the ex-ante estimate of 72,677 tCO₂e.
Red Flags
- Validation report (Jan 2017) recorded 8 compliance-level findings and 8 corrective-action requests covering baseline identification, investment-analysis inputs, monitoring locations, and UNFCCC incompleteness — a high volume of issues for a single validation cycle
- Leakage justification is contradictory: the validation report states 'deemed negligible' while an appendix (5 days earlier) indicates the leakage was 'quantified'; the 0% deduction rests on the weaker justification
- No monitoring-period data, FNRB method, or usage-rate figures were found in any extracted document, so actual credit delivery cannot be independently verified against the 72,677 tCO₂e ex-ante estimate
- Baseline is project-specific and modeled rather than jurisdictional or standardised, increasing sensitivity to input assumptions
