Wenshi AMMS GHG Mitigation Project in Jiangsu Province

Audit Analysis

The Wenshi AMMS biogas project in Jiangsu has VVB-confirmed additionality and a verified ERR of 235,918 tCO₂e for the first monitoring period, delivering roughly 90% of the pro-rata lifetime expectation. However, the project relies on a project-specific modeled baseline, lacks a stated buffer pool, and the verification report identified 11 corrective actions alongside over 25 PDD-level findings including baseline calculation errors, indicating meaningful design and documentation weaknesses.

Project Description

Red Flags

• ⚠11 corrective actions (CARs) raised in the verification report covering calculation errors, missing QA/QC procedures, and incorrect emission factor values
• ⚠Over 25 PDD-level findings including incorrect baseline estimates, outdated IPCC versions, and missing financial indicators for the additionality test
• ⚠No buffer pool percentage stated in any available document for a biogas project with inherent system-failure reversal risk
• ⚠Leakage treatment contradicts between the PDD (not addressed) and the verification report (quantified), with no specific deduction percentage extracted
• ⚠Baseline is project-specific and modeled with no reassessment date recorded
