Score Breakdown

Integrity

verified Additionality is confirmed by the VVB (validation/verification documentation referenced in the record).

missing Baseline is project-specific and the timing of any baseline reassessment is not stated in available documents.

Transparency

verified Claimed and verified ERs match (26,378 tCO₂e) in the monitoring/verification record.

missing Key MRV parameters (e.g., grid emission factor and its vintage) are not found in the extracted record.

Claim Safety

verified The project is explicitly not CORSIA-eligible, reducing aviation-claim overlap risk.

missing Leakage treatment is not fully evidenced (negligible claimed, but no quantified deduction shown).

Documentation

verified Multiple core documents are available (PDD, validation report, monitoring report) with high extraction confidence.

missing Safeguards documentation is inconsistent across documents, reducing reliability.

Detailed Analysis

Integrity

The validation/verification record indicates additionality was assessed using a barrier analysis and confirmed by the VVB (Bureau Veritas Certification). The monitoring/verification outcome shows no material findings and no corrective actions required, which supports procedural integrity. However, the baseline is described as project-specific and the extracted record does not state when (or whether) the baseline was last reassessed, which increases over-crediting risk over time. Leakage is only described as negligible in the monitoring report, but the absence of a stated leakage deduction percentage weakens confidence in completeness of the accounting.

Transparency

The monitoring period is clearly stated (2009-12-10 to 2012-12-31) and the monitoring report shows the same total emission reductions claimed and verified (26,378 tCO₂e), which is a positive transparency signal. The VVB is identified as Bureau Veritas Certification, supporting traceability of assurance. At the same time, key quantitative inputs commonly needed to reproduce results (such as the grid emission factor and the year/vintage used) are not found in the extracted record, limiting independent replicability. Usage monitoring details are also not stated in available documents.

Claim Safety

The project is explicitly marked as not CORSIA-eligible in the extracted record, which lowers the risk of conflicting claims in the aviation context. No CCP status is found in the extracted record, leaving uncertainty for high-integrity buyer claims tied to CCP. The baseline is project-specific and baseline reassessment timing is not stated, which can elevate over-crediting risk if grid or technology conditions changed during the crediting period. Leakage is asserted as negligible in the monitoring report without a quantified deduction, which increases greenwashing/over-crediting risk if leakage pathways exist but were not robustly evidenced.

Documentation

The extracted record indicates availability of core documents (PDD, validation report, monitoring report) and uses multiple documents overall, with high extraction confidence, supporting document completeness. The monitoring report is dated 2013-12-30 and covers a defined monitoring period, suggesting reasonable recency for the issuance vintage assessed. No corrective actions or material findings are reported, which is consistent with a complete verification package. However, safeguards reporting is inconsistent between documents, which reduces confidence that non-carbon requirements were consistently addressed and disclosed.

Overall

Overall quality is moderate: additionality is VVB-confirmed and the ER total is consistent between claimed and verified figures, but several important quantitative elements are missing from the extracted record (grid emission factor details, leakage deduction percentage, and baseline reassessment timing). The key contradiction is on safeguards: the PDD (2010-08-27) indicates safeguards were mentioned, while the monitoring report (2013-12-30) indicates they were not. For scoring, the monitoring report was privileged as the more recent operational document for what was actually reported during monitoring, and this inconsistency was treated as a transparency/documentation reliability issue, lowering those scores. No other contradictions were provided, and no material findings/corrective actions were reported.

Audit Analysis

This VCS biomass energy project has a VVB-confirmed additionality assessment and a clean verification outcome with no material findings, which supports basic credit integrity. However, key quantification elements (notably leakage deduction and baseline reassessment timing) are not clearly evidenced in the extracted record, and safeguards reporting is inconsistent across documents.

Project Description

Yihai Kerry (Jilin) Bio-cogeneration Co., Ltd., a subsidiary of Wilmar International Ltd, owns and operates a green-field rice husk based thermal energy generation system that produces steam. The project uses rice husks purchased from 'Yihai Kerry (Jilin) Oils, Grains and Foodstuffs Industries Co., Ltd' and has two boilers with a capacity of 15 MT/hour each, with no other co-firing provided for.

Red Flags

  • Leakage is described as “deemed negligible” but no leakage deduction percentage is provided in the extracted record.
  • Safeguards are inconsistently reported between the PDD (mentions safeguards) and the monitoring report (does not).

Cosa migliorerebbe questo punteggio

  • Disclose and justify a quantified leakage assessment (including an explicit leakage deduction of 0% if applicable) in the monitoring/verification documentation.
  • Provide the grid emission factor value and the year/vintage (and any updates/reassessments) used for the monitoring period to enable independent replication.

Questi suggerimenti indicano quali prove pubbliche aggiuntive potrebbero migliorare il livello di confidenza di questa valutazione. Non garantiscono un punteggio futuro più alto.
