Puyang County MSW Landfill Site LFG Pollution Treatment and Comprehensive Utilization Project

Audit Analysis

A VCS landfill gas recovery project in China with a VVB-confirmed combined additionality test and conservative credit delivery (approximately 61% of the pro-rata expectation for the elapsed monitoring period). However, eight material findings—including a baseline calculation error using the wrong equation and a direct contradiction on whether LFG capture is legally required—raise meaningful concerns about the robustness of the additionality claim and the accuracy of the underlying calculations. The project's documentation quality is further weakened by a low extraction confidence rating and several unresolved data gaps.

Project Description

Red Flags

• ⚠Eight material findings in the verification report, including use of an incorrect CDM TOOL 05 equation (eq 1 instead of eq 2) for the baseline electricity emissions calculation, which could have inflated or deflated the credit quantity
• ⚠Direct contradiction between the verification report (capture legally required = true) and the validation report (capture legally required = false), undermining the additionality claim if the more recent verification report is correct
• ⚠Grid emission factor discrepancy of 50% between the verification report (0.8587) and the monitoring report (0.57205), with no reconciliation documented
• ⚠Leakage justification is contradictory: the verification report states 'quantified' while the monitoring report states 'deemed negligible', yet both documents assign a 0% deduction
