Veolia LFG PTA Manizales and Cúcuta Landfill
#93of 189 in Methane#79of 124 in Colombia#59of 99 in CerCarbono (CC)#86of 159 in ACM0001
Audit Analysis
A landfill gas capture project under the mature ACM0001 methodology with VVB-confirmed additionality, but undermined by material findings (115 omitted records, calibration delays), a contradictory leakage justification, and a significant discrepancy between the monitoring report and issuance ERR figures. The project-specific modeled baseline and absence of a stated buffer pool further weaken the integrity profile.
Red Flags
- Omission of 115 records in the Cúcuta site emission reduction calculation, flagged as a Corrective Action Request in the verification report
- Contradictory leakage justification: the verification report states 'quantified' (2024-02-16) while a same-document entry dated 2024-02-15 states 'deemed negligible', with a 0% deduction applied
- ERR discrepancy: the monitoring report records 55,343 tCO2e while the issuance document records 109,906 tCO2e for the same period, a factor-of-two gap unexplained in the extracted record
- Low extraction confidence across the document set, indicating at least one key document was poorly readable
