Shilichong AMWS GHG Mitigation Project

Audit Analysis

The Shilichong AMWS biogas project in China is a Gold Standard project with a VVB-confirmed combined additionality test and no reported reversal events, but it carries moderate risks from a project-specific modeled baseline, a leakage treatment contradiction between the PDD and verification report, and four corrective actions required in the monitoring report. The 2024 verified ERR of 174,033 tCO₂e represents roughly 106% of the pro-rata lifetime expectation, indicating the project is delivering close to its ex-ante estimate.

Project Description

Red Flags

• ⚠Leakage treatment is contradictory: the PDD (2024-11-21) states leakage was 'deemed negligible' while the verification report (2024-11-25) states it was 'quantified'; the actual deduction percentage is not stated in either document
• ⚠Four corrective actions were required in the monitoring report (missing milestone table, missing FAR response, missing MCFj data source, missing sampling method description), indicating documentation gaps in the MR
• ⚠Baseline is project-specific and modeled, with no record of a baseline reassessment date; the grid emission factor of 0.57335 tCO₂/MWh (2023) is the only quantified baseline parameter available
• ⚠FNRB value, usage monitoring method, and buffer pool percentage are all absent from the extracted record, leaving key MRV parameters unverified
