Audit Analysis
The Zhangjiakou LFG project is a well-established landfill gas capture project with verified additionality and no inherent reversal risk, but the 2025 verification cycle surfaced 15 material findings and 18 corrective actions, including an incorrect baseline emission equation and a flagged grid emission factor error. Multiple contradictions between documents (FPIC status, baseline type, additionality test type, leakage justification) and a low extraction confidence rating undermine confidence in the data record. The project is in a declining production phase, with verified credits roughly halved compared to the 2021 period, partly explained by a lower grid emission factor.
Red Flags
- The 2025 verification report identified an incorrect equation for calculating total baseline emissions during the crediting period in the ER calculation spreadsheet, raising questions about the accuracy of verified credits
- Grid emission factor values and sources in the 2025 verification report were flagged as incorrect in the material findings, yet the 0.7129 (2017) value was used for credit calculation
- Reported operating hours of 8,784 in 2024 exceeded the registered project description estimate of 8,500 without initial explanation
- Electricity generation for 7 months in 2023 was higher than the full year 2024, requiring justification that was not provided
- FPIC status is directly contradicted between the verification report (conducted) and the monitoring report (not conducted), both dated 2025-12-09
