Veolia LFG PTA Presidente landfill

Audit Analysis

The Veolia LFG PTA Presidente landfill project has a VVB-verified additionality assessment and a measured baseline, but is undermined by a large volume of material findings (18,207 missing records, calibration errors, wrong calibration gas), a 0% leakage deduction with contradictory justifications, and a verified emission reduction of only ~36% of the pro-rata lifetime expectation for the elapsed monitoring period. Seven cross-document contradictions and low extraction confidence further erode confidence in the data record.

Project Description

Red Flags

• ⚠18,207 raw data records omitted from Flare 1 December monthly spreadsheet, flagged three times in material findings and requiring corrective action
• ⚠Zero calibration of continuous gas analyzers performed with air instead of certified inert gas, compromising measurement integrity
• ⚠Verified ERR of 49,248 tCO2e is only ~36% of the pro-rata lifetime expectation (~136,500 tCO2e) for the 11-month monitoring period, suggesting the ex-ante estimate may be overstated
• ⚠Seven contradictions across documents, including grid emission factor (1.3 vs 0.25), baseline type (measured vs modeled), and leakage justification (quantified vs deemed negligible)
• ⚠No buffer pool percentage stated and no reversal event data available, leaving permanence risk unquantified
