Ancon – EcoMethane Landfill Gas Project

Audit Analysis

The Ancon EcoMethane landfill gas project in Peru has a solid additionality foundation (combined test confirmed by DNV) and no material compliance failures, but suffers from significant data gaps in the extracted record: the verified ERR is absent, no permanence mechanism is documented, and the leakage treatment is contradictory across documents. The project-specific modeled baseline and the unresolved leakage justification create moderate over-crediting risk.

Project Description

Red Flags

• ⚠Leakage justification is contradictory: the validation report (2007) states leakage was 'deemed negligible' while the monitoring report (2009) records it as 'not addressed', leaving the 0% deduction without a clear, consistent basis
• ⚠Verified ERR for the monitoring period (Nov 2007 – Jan 2009) is not available in the extracted record, preventing any pro-rata delivery check against the 483,083 tCO2e lifetime claim
• ⚠No buffer pool, permanence mechanism, or reversal-risk mitigation is documented for this 7-year crediting period
• ⚠One of the four evidence documents is listed as 'unknown', reducing confidence in the completeness of the documentary record
