Analysis

A CDM landfill-gas-to-electricity project in China with VVB-confirmed additionality and a conservative grid emission factor, but undermined by a seven-fold discrepancy in the ex-ante lifetime credit estimate, multiple material findings on data quality (swapped entries, missing flare metering), and a baseline characterization that differs between the validation and monitoring reports. The project over-delivered relative to its pro-rata expectation, which is reassuring, yet the volume of unresolved data-quality issues and the unresolved ex-ante discrepancy limit confidence in the credit volume.

Being within an ICVCM-approved version range is information only: it does not mean these credits carry the CCP label, which the registry assigns to each issuance.

A version is shown only when the document's own text writes it next to the methodology code. Current versions, status and CCP ranges come from the official pages linked, checked on the date shown.
