Curva de Rodas and La Pradera landfill gas management project

Audit Analysis

A CDM landfill gas management project in Colombia using the well-established ACM0001 v19.0 methodology, with a 7-year crediting period (2016–2023) and a total of 1,616,428 tCO₂e claimed and verified. The validation report identified six material findings, including baseline scenario transparency gaps and an inconsistency in the methane destruction efficiency factor, all of which required corrective action. Key data on additionality testing, FNRB, usage monitoring, and monitoring periods were not found in the extracted record, limiting the depth of assessment.

Project Description

Red Flags

• ⚠Six material findings in the validation report, including a baseline scenario transparency gap and an FCH4,BL inconsistency (0% vs 2% adjustment factor) between the PDD and the registered version
• ⚠Total ERR claimed and total ERR verified are identical (1,616,428 tCO₂e), which is highly unusual and may indicate a data extraction or reporting issue rather than a genuine match
• ⚠Additionality test type and VVB verification status are not found in the extracted record, leaving the additionality assessment unconfirmed
