Dongxing Waste Incineration Plant leachate biogas Harmless Treatment and Comprehensive Utilization Project

Audit Analysis

This VCS biogas project (VCS-3851) in China has a verified investment-test additionality and a measured baseline, but the verification report flagged eight material findings including an incorrect additionality demonstration and methodology scope errors. A significant grid emission factor discrepancy (0.8587 vs 0.57205) between the verification and monitoring reports undermines confidence in the credit quantity, and the leakage justification is inconsistent across documents. The project delivered roughly 93% of its pro-rata ex-ante expectation for the elapsed monitoring period, which is reasonable, but the documentation quality and internal consistency are below standard.

Project Description

Red Flags

• ⚠Grid emission factor contradicts between the verification report (0.8587) and the monitoring report (0.57205), both dated 2024-06-19, creating uncertainty about the correct credit quantity
• ⚠The verification report lists 'Incorrect additionality demonstration' and 'Incorrect Scope and applicability condition of AMS-III.H' as material findings, indicating fundamental methodology application errors
• ⚠Leakage justification is inconsistent: the verification report states 'quantified' while the monitoring report states 'deemed negligible', both for a 0% deduction
• ⚠Eight material findings were identified during verification, including missing project boundary, missing GHG source identification, and missing monitored parameter TDLj,y
• ⚠Minimum extraction confidence across the document set is rated low, reducing reliability of the extracted data
