Boiler Second Economizer in Yansab, Kingdom of Saudi Arabia
#734of 1459 in CDM (UNFCCC)#5of 12 in AMS-II.D
Audit Analysis
A CDM boiler economizer project in Saudi Arabia with VVB-confirmed additionality and inherently low permanence risk, but undermined by 14 material findings at validation, a project-specific baseline, and a monitoring-period ER figure that exceeds the ex-ante lifetime estimate by a factor of roughly four. The project is functional but carries elevated over-crediting risk and documentation-quality concerns.
Red Flags
- Monitoring-period ERs (28,743 tCO2e, 2017–2019) exceed the ex-ante lifetime estimate (23,018 tCO2e, validation report 2016) by approximately 4.2× on a pro-rata basis, raising serious over-crediting concerns
- 14 material findings (CARs) at validation covering baseline data, monitoring plan, PDD inconsistencies, and stakeholder-consultation timing, plus 1 unresolved FAR on calibration frequency
- Project-specific baseline with no documented reassessment schedule; baseline data and boiler remaining-life documentation were flagged as insufficient (CAR#06, CAR#14)
