*Mamak Landfill Waste Management Project , Turkey

Audit Analysis

The Mamak Landfill Gas-to-Energy project in Turkey has a VVB-confirmed investment additionality test and a project-specific baseline reassessed in 2021, but is undermined by significant operational underperformance (gasifier not operating as planned, digester feeding only 2 of 6 engines), a 0% leakage deduction, no stated buffer pool, and unaddressed reversal risk. The VVB (Applus+) identified numerous material findings and corrective actions, and verified emissions reductions at only 83.5% of the project's claimed figure for the same monitoring period. Documentation is voluminous (33 documents) but suffers from low extraction confidence and persistent PDD quality issues.

Project Description

Red Flags

• ⚠Gasifier system not operating as planned and anaerobic digester feeding only 2 of 6 expected engines, resulting in actual emissions reductions (528,679 tCO2e) well below PDD estimates (665,717 tCO2e)
• ⚠No buffer pool percentage stated in any available document, and reversal events explicitly not addressed
• ⚠0% leakage deduction with only a 'quantified' justification label — no specific quantification or methodology detail found in the extracted record
• ⚠FNRB value and FNRB method not stated in any available document
• ⚠Low extraction confidence across the document set, indicating at least one key document was poorly readable
