IBB Waste Incineration and Power Generation Plant Project

Audit Analysis

The IBB Waste Incineration project in Turkey has a VVB-verified combined additionality test and a low permanence risk inherent to its avoidance-based design, but is undermined by multiple calculation errors caught during verification (including a 1,000× N₂O emission-factor error and a 3.3× DOCj correction), a project-specific modeled baseline, and a significant under-delivery of roughly 28% of the pro-rata ex-ante expectation for the elapsed monitoring period. Five cross-document contradictions—spanning leakage treatment, ERR figures, additionality status, benefit-sharing, and crediting period—reduce confidence in the internal consistency of the project record.

Project Description

Red Flags

• ⚠N₂O emission factor (EFN2O,t) was off by a factor of 1,000 in the original PDD and had to be corrected during verification, indicating a fundamental unit-conversion error in the ex-ante calculation.
• ⚠The project delivered only ~28% of the pro-rata ex-ante expectation for the elapsed monitoring period (1,090,991 tCO₂e verified vs. ~3,872,000 tCO₂e expected), raising questions about the validity of the original 8,760,720 tCO₂e lifetime estimate.
• ⚠Leakage treatment is contradictory: the verification report (2024) states leakage was 'quantified' while the monitoring report (2026) states it was 'deemed negligible,' with a 0% deduction applied in both cases.
• ⚠Eight corrective actions remain open, including a VVB onsite inspection, capacity-figure correction to align with the generation license, and clarification of the PEINC zero value.
• ⚠FPIC was not conducted, and the PDD (2017) originally recorded additionality as unverified and benefit-sharing as absent, both of which were only later confirmed in subsequent documents.
