TTCA ORGANIC COMPOSTING PROJECT IN ATTAPEU

Audit Analysis

The TTCA Organic Composting Project in Attapeu is a VCS-registered waste-management project (AMS-III.F) with VVB-confirmed additionality and low inherent permanence risk, but it is undermined by five material findings in the verification report, a project-specific modeled baseline, a thin 0% leakage justification, and a significant unexplained discrepancy in ERR figures across documents (4,375 vs. 353,061). The project delivered 100% of the pro-rata expectation for its first monitoring period, but documentation gaps and data inconsistencies limit confidence in the overall credit quality.

Project Description

Red Flags

• ⚠Unexplained ERR discrepancy: the PDD (Feb 2025) and verification report both state 4,375 tCO₂e for the monitoring period, but an appendix (Jan 2025) lists 353,061 — a factor of ~80 difference that is not reconciled in any available document.
• ⚠Five material findings in the verification report, including calibration of monitoring equipment performed after the monitoring period started, missing emission parameters (EFEF, ECpj) in the monitoring plan, and an investment-analysis benchmark (11.9%) that was not clearly demonstrated.
• ⚠Leakage deduction of 0% justified only as 'deemed negligible' in the verification report, while the PDD (Apr 2023) originally did not address leakage at all — a thin basis for a waste project where displaced waste could be managed elsewhere.
