Analysis

A Gold Standard landfill-gas-to-power project in China with VVB-confirmed additionality and a legally mandated capture obligation, but undermined by a significant grid emission factor discrepancy between the verification and monitoring reports, a project-specific modeled baseline, and the absence of key operational parameters such as FNRB values, usage rates, and an LCA. The claimed and verified ER figures match exactly at 107,303 tCO₂e for the 2023 monitoring period, but the underlying data inconsistencies and missing sustainability documentation limit confidence in the robustness of the credit.

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.
