Lingbi County Wastewater Treatment Plant Project

Audit Analysis

The Lingbi County Wastewater Treatment Plant project has a solid additionality foundation confirmed by a well-known VVB and low inherent permanence risk, but is undermined by a project-specific modeled baseline, five material findings (including parameter errors and a 17.65% under-delivery), and multiple cross-document contradictions. The project is under-delivering relative to its ex-ante estimate, which limits over-crediting risk but raises questions about the robustness of the original calculations.

Project Description

Red Flags

• ⚠Five material findings in the verification report, including incorrect parameter source values (CODBL,WW,y, CODPJ,WW,y, ADBL) and a CH4/CO2 misidentification in the major emission sources table, indicating calculation and reporting errors that required corrective actions.
• ⚠The actual emission reduction is 17.65% lower than the registered PDD estimate, attributed to lower influent flow/COD and higher electricity consumption, suggesting the ex-ante assumptions were optimistic.
• ⚠Six contradictions across documents, including conflicting ERR figures (95,511 vs 76,591) within the same monitoring report, conflicting additionality test descriptions (investment vs combined), and conflicting FPIC and benefit-sharing statements.
