24MW Power Generation from Coking Waste Heat Generated in the Clean-type Heat-recovery Coke Ovens at Shanxi Sinochem Wonder Industries Co. Ltd.

Integrity

The validation report from Det Norske Veritas Certification AS confirms additionality through an investment test, which supports the project’s core integrity case. However, leakage is not addressed in the validation material, no buffer pool or reversal protection is stated, and the extracted record shows two corrective action requests. Overall integrity is therefore only moderate.

Transparency

The project has a named VVB and a clearly stated monitoring period, which helps traceability. But the extracted record does not provide verified or claimed emission reduction totals, and key operational details such as leakage treatment and usage monitoring are missing. Low extraction confidence further weakens transparency.

Claim Safety

Claim safety is constrained by missing leakage treatment and the absence of quantified emission reduction figures in the extracted record. The project uses ACM0004 with a project baseline, but the record does not show a recent reassessment or robust public accounting details. The contradiction between an investment test in the validation report and a benchmark test in the PDD adds some reliability concern.

Documentation

Documentation is mixed: seven documents were used, including a validation report and PDD, and FPIC is mentioned. Still, two corrective action requests were required, and the extraction confidence is low, indicating at least one key source was difficult to read. The crediting period and leakage treatment also appear inconsistently reported across documents.

Overall

I privileged the validation report over the PDD where the two conflict, because it is the later validation document and the VVB-reviewed source; that means the investment test is treated as the stronger additionality evidence, while the benchmark-test reference is treated as a contradiction. I also privileged the validation report’s statement that leakage is not addressed over the later unidentified source claiming a quantified approach, because the latter is not clearly attributable and the extracted record does not preserve enough detail to rely on it. The crediting period discrepancy between the PDD and the later unknown source is another reliability issue, and together with low extraction confidence and two corrective action requests, it justifies a downward adjustment to the confidence in the claim.
