Dongdongtan 9MWp Solar PV Project

Audit Analysis

The Dongdongtan 9 MWp solar PV project has a verified investment-test additionality assessment and no reported reversal events, but the use of a 2013 grid emission factor for 2024 monitoring raises a material over-crediting risk. The absence of a verified ERR figure prevents any cross-check of the 86,611 claimed credits, and six inter-document contradictions (baseline method, leakage justification, crediting period, and others) weaken confidence in the data record.

Project Description

Red Flags

• ⚠Grid emission factor of 0.856875 tCO₂/MWh is from 2013 but applied to a 2024 monitoring period; China's grid has become significantly cleaner since then, so the displacement benefit is likely overstated.
• ⚠Total verified ERR is not found in any available document, making it impossible to cross-check the 86,611 claimed credits against independently verified figures.
• ⚠Six contradictions exist across documents, including baseline method (project-specific vs jurisdictional), leakage justification (not addressed vs deemed negligible), and crediting period (2013–2020 vs 2020–2027), indicating inconsistent record-keeping.
• ⚠Leakage deduction is 0% with the 2022 verification report stating the justification was 'not addressed,' while the 2015 report called it 'deemed negligible'—the more recent document provides no explicit rationale.
