AWMS Methane Recovery Project BR06-S-23, Mato Grosso and Goias, Brazil
#60of 104 in Brazil#144of 213 in CDM (UNFCCC)#31of 62 in AMS-III.D
Audit Analysis
A CDM anaerobic digestion project (AMS III.D) with solid additionality confirmed by DNV via a combined test, but significant gaps in leakage treatment, permanence documentation, and a notable under-delivery relative to the pro-rata lifetime estimate. Four material findings from the validation process, including a debundling risk, further weaken confidence in the credit claims.
Red Flags
- Leakage explicitly not addressed in available documents for a methane recovery project where fugitive emissions and displaced-manure pathways are plausible
- Monitoring period delivered only ~29% of the pro-rata lifetime expectation (11,561 vs ~39,853 tCO2e), raising questions about baseline robustness
- Validation report identified a debundling risk regarding new digesters within 1 km (CR 5), which could undermine additionality over time
- No verification report or post-project monitoring beyond 2010 found in the extracted record; the project's crediting period ended in 2018 with no evidence of continued MRV
