Reducing Gas Leakages within the Titas Gas Distribution Network in Bangladesh - CER Conversion

Integrity

Additionality appears reasonably supported because the validation/verification documentation indicates a combined additionality test and that additionality was confirmed by the VVB. However, the monitoring report does not evidence any leakage assessment or deduction, and the extracted record does not show when the baseline was last reassessed, which weakens confidence in baseline validity over time. No buffer pool contribution is stated and reversal information is not found in the extracted record; while this is an avoidance methane project (lower reversal risk than removals), the absence of explicit permanence/risk provisions still reduces robustness.

Transparency

The monitoring report (2021-02-09) provides a clear monitoring period (2019-11-08 to 2020-12-31) and identifies the VVB as TÜV SÜD South Asia Private Limited. Transparency is weakened by the volume and nature of corrective actions in the monitoring report, including requests to reconcile leak counts, document instrument calibration details, and align uncertainty values between the monitoring report and calculation sheets. The extracted record also lacks key quantified MRV elements (e.g., leakage deduction, baseline reassessment date), limiting reproducibility from the public-facing data captured here.

Claim Safety

The project is explicitly marked as not CORSIA-eligible, which lowers the risk of certain eligibility-based claims. Nonetheless, over-crediting risk is elevated by contradictory total emission reduction figures across documents and by auditor-identified issues in the monitoring report, including uncertainty mismatches and a flagged methane GWP choice that may not align with the applicable guidance referenced by the auditor. The absence of an evidenced leakage treatment further increases the risk that credited reductions could be overstated.

Documentation

Documentation coverage is moderate-to-good given 33 documents used and high extraction confidence, and the monitoring report is relatively recent (2021-02-09). However, the monitoring report lists multiple corrective actions that indicate documentation and internal consistency gaps (e.g., missing calibration inventory, unclear data flow description, and calculation procedure clarifications). The presence of an “unknown” document type in the evidence list and multiple cross-document inconsistencies reduce confidence that the record is fully coherent.

Overall

Overall quality is mid-range: additionality is VVB-confirmed and the project uses an established CDM methodology (AM0023), but the extracted record shows weak leakage treatment evidence and several MRV/reporting issues. Contradictions materially affect reliability: for total ERR claimed, 3,838,690 (validation report dated 2020-06-05) conflicts with 4,378,506 (validation report dated 2019-07-17); the more recent 2020 figure is privileged, but the inconsistency lowers confidence. For total ERR verified, 4,049,551 (validation report dated 2021-07-21) conflicts with 3,481,722 (validation report dated 2020-06-05); the more recent 2021 figure is privileged, but the fact that both are labeled as validation reports is a documentation-quality concern. For the crediting period, 2017-01-29 to 2027-01-28 (monitoring report dated 2021-02-09) conflicts with 2015-04-01 to 2025-03-31 (validation report dated 2015-03-16); the more recent monitoring report dates are privileged, but the discrepancy suggests a need for clear registry-aligned confirmation.
