Dongdongtan 9MWp Solar PV Project

Integrity

The verification report by Shenzhen CTI (document dated 2024-11-12) confirms additionality via an investment test, which supports basic integrity. However, the project shows a 0% leakage deduction while the latest documents state leakage justification is not addressed, and the buffer pool percentage is not provided in the extracted record—these are material weaknesses. Several corrective actions and clarification requests were raised and closed (listed in the validation/verification materials), which indicates issues were found and remediated but reduces confidence in robustness.

Transparency

Project transparency is mixed: the VVB is named and a current monitoring period (2024-01-01 to 2024-12-31) and smart meter monitoring are documented, which helps traceability. But total emissions reductions verified is not provided in the extracted record (total_err_verified missing), evidence documents are listed as 'unknown', and extraction confidence is only medium, limiting transparency.

Claim Safety

The project uses an established methodology (AMS I.D. v3.0) and reports a grid emission factor (0.856875), which supports claim defensibility. Conversely, leakage treatment is weak (0% deduction without documented justification in the latest documents) and national/regional factors (FNRB) are not applicable or absent, raising over‑crediting risk. CORSIA/CCP status is not stated, so dual‑claim risk cannot be ruled out.

Documentation

Documentation breadth is moderate: 17 documents were used and the most recent document date is 2024-11-12 with a named VVB. However, evidence documents are not clearly identified (listed as 'unknown') and extraction confidence is medium, indicating some source reliability issues. Multiple corrective actions were required and closed; that is positive for follow-up but the original issues lower documentation quality.

Overall

I privileged the more recent and more specific document entries when contradictions occurred. For additionality test type I privileged the 2022-11-11/2022-05-07 era confirmation that the test is investment-based (prefer the 2022 record over 2014 as more recent). For benefit sharing, I accepted the 2022 record that benefit sharing is not described rather than the 2014 record that it was; the later document is treated as authoritative. For leakage, I privileged the later 2022 entry stating leakage is not addressed over an earlier 2020 note that deemed leakage negligible; the absence of a justification in the later documents reduces scores. For reversal events I accepted the 2024 statement that none were reported. For crediting period, I privileged the later 2022-11-11 record showing the 2013–2020 period over an earlier 2022-05-07 note suggesting 2020–2027, because the 2022-11-11 entry is later and explicitly appears in the validation materials. These contradictions and the medium extraction confidence reduce overall reliability and pull scores down despite VVB confirmation of additionality. The composite weighted score is 5.1.
