Istanbul 3rd Airport Rail System Connection by Republic of Türkiye MoTI
#47of 75 in TR#96of 154 in Intl. Carbon Registry (ICR)#3of 5 in ACM0016
Audit Analysis
The Istanbul 3rd Airport Rail System Connection is a large-scale avoidance project (81.6 MtCO₂e over 10 years) with strong permanence characteristics due to its 100-year infrastructure design life, but the available documentation is limited to a PDD and appendix with no verification or monitoring reports. Additionality is assessed via a combined test but lacks independent VVB confirmation, and the 0% leakage deduction rests on a thin 'deemed negligible' justification. The overall evidence base is insufficient to confirm the claimed emission reductions.
Red Flags
- No VVB is identified and no verification report appears in the document set; additionality is assessed but independently unconfirmed
- Methodology ACM0016 V6.1 is titled 'Energy Efficiency Improvements in Buildings' yet is applied to a rail-system connection — the applicability to transport infrastructure is not explained in the extracted record
- FPIC was not conducted (explicitly recorded as false) even though safeguards and benefit-sharing are mentioned, creating a gap in free, prior and informed consent for affected communities
- No monitoring report or verified ERR figure is available; the 81.6 MtCO₂e claim rests entirely on the ex-ante PDD estimate
- Low extraction confidence on the two available documents (PDD and appendix) reduces reliability of all extracted values
