Zhengbang AWMS GHG Mitigation Project in Guangdong Province

Audit Analysis

The Zhengbang AWMS project in Guangdong Province is a registered VCS anaerobic waste management project with VVB-confirmed additionality, but its integrity is undermined by a project-specific modeled baseline, a non-permanence analysis that is simply marked 'N/A', and 22 corrective action requests that exposed significant calculation and documentation gaps. The project delivered roughly 50–77% of its pro-rata ex-ante expectation for the elapsed monitoring period, which is conservative, but contradictions in verified emission reduction figures and a low extraction confidence level reduce confidence in the reported data.

Project Description

Red Flags

• ⚠22 corrective action requests (CARs) were raised during verification, including missing formulas for baseline/project/leakage emissions, inconsistent day-count parameters (180 vs 365), and unit errors — all closed but indicating weak initial MRV quality
• ⚠Contradiction in verified ERR: the monitoring report (Oct 2023) reports 261,094 tCO₂e while the verification report (Jun 2023) reports 167,962 tCO₂e, and the monitoring report is dated after the verification report, raising questions about which figure was actually verified
• ⚠Minimum extraction confidence is rated 'low', indicating at least one key document was poorly readable, reducing reliability of the extracted data
