Wenshi AMMS GHG Mitigation Project in Anhui Province

Audit Analysis

The Wenshi AMMS biogas project in Anhui Province has a VVB-confirmed additionality assessment and no material findings, but is held back by a project-specific modeled baseline, a leakage treatment contradiction between the PDD and verification report, and eleven corrective actions flagging monitoring and QA/QC gaps. The verified ERR for the first monitoring period is roughly 88% of the pro-rata lifetime expectation, indicating no over-crediting but also no surplus delivery.

Project Description

Red Flags

• ⚠Eleven corrective actions in the verification report cover monitoring methodology, QA/QC procedures, data consistency (Np,LT values), calibration, and social indicators — indicating a monitoring process with multiple unresolved weaknesses.
• ⚠Leakage treatment is contradictory: the PDD states leakage was 'not addressed' while the verification report records it as 'quantified'; the specific deduction percentage is not stated in any document.
• ⚠Baseline is project-specific and modeled, with no reassessment date recorded; the grid emission factor (0.48665 tCO₂/MWh, 2023) is a single-year value with no stated update mechanism.
