Analysis

This CDM HFC23 thermal oxidation project at Jiangsu Meilan Chemical has a VVB-verified additionality assessment and a measured project-specific baseline, but is severely undermined by repeated monitoring-period failures: negative GHG reductions, HFC23 generation rates consistently exceeding the maximum eligible threshold, and at least one period with zero eligible credits due to cap breaches. Multiple contradictions across documents—including a three-fold discrepancy in the lifetime ex-ante estimate and inconsistent leakage treatment—raise serious data-reliability concerns.
