The project of Kitchen and catering waste Disposal Phase II in Wuchang area

Audit Analysis

A VCS waste-disposal project in Wuchang, China, with VVB-verified additionality and inherently low reversal risk, but undermined by a project-specific baseline, contradictory leakage treatment across documents, a material GWP error (N₂O at 298 instead of 265), and six material findings that required 12 clarification and 7 corrective-action requests. The identical claimed and verified ERR figures (641,226) suggest the verification confirmed the ex-ante PDD estimate rather than independently measured performance, limiting confidence in the credit quantity.

Project Description

Red Flags

• ⚠GWP value for N₂O erroneously stated as 298 instead of 265 (IPCC AR5), overstating N₂O-related reductions by roughly 12% until corrected
• ⚠Project emissions from incineration of dewatered digestate were initially omitted from the ER estimation, meaning the original credit quantity was overstated
• ⚠Leakage treatment is contradictory: the PDD (May 2023) deems leakage negligible while the validation report (Sep 2024) describes it as quantified, and the leakage deduction percentage is not stated in any document
• ⚠Capture of methane is stated as legally required in an appendix but not in the validation report, creating ambiguity about whether the project is truly additional
• ⚠Total ERR claimed and total ERR verified are identical (641,226), indicating the verification confirmed the PDD estimate rather than independently verifying measured performance
