Yangxiang AWMS GHG Mitigation Project In Shandong Province

Audit Analysis

The Yangxiang AWMS project in Shandong is a registered VCS waste-methane avoidance project with VVB-confirmed additionality and consistent first-period ERR figures, but it carries moderate risk from a project-specific modeled baseline, absence of a stated buffer pool, under-delivery relative to the pro-rata PDD expectation (~70%), and a set of unresolved corrective actions from the verification report. The project is functional but not high-assurance.

Project Description

Red Flags

• ⚠PDD lifetime ERR estimate (1,190,572 tCO₂e) is roughly 8× the first-period verified figure (144,879 tCO₂e); the project delivered only ~70% of the pro-rata expectation for the 21-month monitoring window, signalling potential over-crediting in the ex-ante design.
• ⚠No buffer pool percentage is stated in any available document, and the verification report marks non-permanence risk as 'N/A' without a quantified reversal-risk analysis, leaving permanence protection unverified.
• ⚠Seven corrective actions were required by the VVB (Carbon Check India), including updating tool versions, completing monitoring tables, and fixing equation errors, indicating the project documentation was not fully compliant at verification.
• ⚠Leakage is described as 'quantified' in the justification field, yet no actual deduction percentage appears in any extracted document, creating an evidentiary gap on a key integrity parameter.
