Akhangaran Landfill Gas Capture Project in Tashkent

Audit Analysis

A CDM landfill gas capture project in Uzbekistan using the standard ACM0001 methodology, with a combined additionality test and non-mandatory capture supporting additionality. However, the absence of any verified monitoring data, a project-specific modeled baseline, a contradiction in the leakage treatment between the PDD and validation report, and four material findings at validation limit confidence in the project's data integrity and claim safety.

Project Description

Red Flags

• ⚠No verified monitoring data or verified ERR figures are available in the extracted record, making it impossible to confirm actual emission reductions against the 469,068 tCO2e lifetime claim
• ⚠Contradiction between the PDD (leakage 'quantified') and the validation report (leakage 'deemed negligible') creates ambiguity about whether leakage was actually calculated or simply assumed away
• ⚠Crediting period discrepancy: the PDD references a 14-year period (2011–2024) while the validation report approves only 7 years (2017–2024), raising questions about whether the PDD's ex-ante estimates were calibrated to the correct timeframe
• ⚠Four material findings at validation (CL 01–03, CAR 01) indicate the PDD contained internal inconsistencies in the baseline and project description that required corrective action before approval
