Tieqilishi Sichuan Liangshan AWMS GHG Mitigation Project

Audit Analysis

The Tieqilishi AWMS project has a VVB-verified additionality assessment and a quantified leakage treatment, but the verification report identifies 16 material findings spanning methodology versioning, project boundary definition, ERR consistency, and ownership documentation. The ex-ante lifetime ERR was revised downward by roughly 40% between PDD versions, and the first monitoring period delivered only about 78% of the pro-rata expectation, raising over-crediting concerns. Overall, the project's credit integrity is undermined by numerous unresolved documentation and methodological gaps.

Project Description

Red Flags

• ⚠16 material findings in the verification report, including ERR inconsistency during the monitoring period, project boundary not correctly defined, and use of outdated IPCC and JPM template versions
• ⚠Ex-ante lifetime ERR dropped from 4,783,350 (PDD Nov 2022) to 2,845,880 (PDD Jun 2023), a ~40% reduction indicating initial over-estimation
• ⚠First monitoring period delivered only ~78% of the pro-rata expectation (315,108 vs ~403,150), suggesting the baseline may be overstated
• ⚠9 corrective actions remain, including clarification of applicability conditions, meter calibration frequency, and project ownership linkage to swine farms
