AWMS Methane Recovery Project MX06-S-45, Coahuila, México
#23of 27 in Mexico#202of 213 in CDM (UNFCCC)#55of 62 in AMS-III.D
Audit Analysis
A CDM methane recovery project from agricultural waste in Coahuila, Mexico, validated by TÜV SÜD in 2006. Additionality is confirmed via a barrier test, but the project suffers from a significant ERR discrepancy between the PDD and validation report, a project-specific modeled baseline, no stated buffer pool, and numerous material findings requiring corrective action. No monitoring reports or verified emissions data are available in the extracted record.
Red Flags
- ERR discrepancy of ~68% between PDD (167,690 tCO2e) and validation report (99,850 tCO2e) indicates the project proponent initially over-claimed credits
- No buffer pool or permanence mechanism stated for a methane recovery project with inherent reversal risk if flare or capture equipment fails
- Ten material findings and seven corrective actions identified during validation, including unclear flare efficiency measurement and missing solid separator in baseline
- No monitoring reports or verified emissions data found in the extracted record; project performance cannot be independently assessed
- Leakage treatment contradicted between PDD (not addressed) and validation report (deemed negligible)
Credit Vintages
