Dois Arcos Landfill Gas Project Activity

Audit Analysis

The Dois Arcos Landfill Gas Project has VVB-confirmed additionality and a conservative 5% leakage deduction, but is undermined by significant monitoring gaps (no flow meter or gas analyser for flared gas, truck deliveries unmonitored at the consumer level), a large discrepancy in claimed ERR between the validation and monitoring reports, and a heavy load of corrective actions and material findings. The absence of verified ERR figures, FNRB data, and usage-rate information limits the ability to confirm that claims are safe.

Project Description

Red Flags

• ⚠Monitoring report (2024) reports that LFG sent to flare was not monitored due to lack of a flow meter or gas analyser, and truck-delivered LFG was not measured at the consumer level — fundamental MRV gaps for a landfill gas project.
• ⚠Claimed ERR differs by 35% between the validation report (60,283 tCO₂e) and the monitoring report (81,410 tCO₂e), with no clear explanation for the increase.
• ⚠Seven corrective actions were required during validation, including CAR 19 (PDD template non-compliance) still open in the third round, indicating persistent documentation quality issues.
• ⚠No verified ERR figure was found in any available document, preventing independent confirmation of claimed reductions.
