Integrity

The monitoring/verification record indicates additionality was confirmed by the VVB using an investment test (validation/verification documentation referenced in the extracted record). The baseline is described as project-specific (extracted record), but the timing of any baseline reassessment is not stated in available documents, which weakens confidence in baseline validity over time. Leakage is explicitly noted as not addressed in the monitoring report (2012), and no leakage deduction is stated, which is a substantive integrity gap for credit quantification.

Transparency

The monitoring report (2012-10-24) provides a defined monitoring period (2011-03-01 to 2012-06-30) and identifies the VVB as SGS United Kingdom Ltd, supporting audit traceability. However, the extracted record shows a major inconsistency between claimed and verified emission reductions (249,802 claimed vs 286,328 verified), which reduces transparency on how figures were derived and reconciled. Several MRV-relevant fields (e.g., grid EF year, usage monitoring method) are not stated in the extracted record.

Claim Safety

The project is explicitly not CORSIA-eligible (extracted record), which lowers the risk of certain aviation-related claims and associated double-claiming narratives. Nonetheless, the mismatch where verified ERs exceed claimed ERs (monitoring/issuance figures in the extracted record) increases perceived over-crediting and reporting risk for external claims. Leakage being not addressed in the monitoring report (2012) further increases greenwashing risk because stakeholders cannot see how potential upstream/downstream effects were handled.

Documentation

The evidence set includes key document types (monitoring report, validation report, PDD, issuance) with high extraction confidence, supporting a relatively strong documentation score. No material findings or corrective actions are reported in the extracted record, which is a positive signal for audit outcomes. However, contradictions across documents (crediting period and whether safeguards are mentioned) indicate that the documentation is not fully coherent and requires reconciliation.

Overall

Overall scoring is pulled down primarily by (1) leakage not being addressed in the monitoring report (2012) and (2) internal inconsistencies in the extracted record. For the safeguards contradiction (monitoring report says safeguards not mentioned; PDD says safeguards mentioned), the PDD (2013-02-06) is more specific to project design disclosures, so it is privileged for whether safeguards are at least discussed, but the absence of FPIC and a grievance mechanism in the extracted record still indicates weak safeguards implementation. For the crediting period contradiction (monitoring report: 2009-07-01 to 2016-06-30; validation report: 2002-07-01 to 2009-06-30), the monitoring report period is privileged as it aligns with the stated monitoring period and later operational crediting context, but the discrepancy materially reduces confidence and warrants a score penalty for reliability. Note: gate rules may cap scores post-processing if documentation or integrity fall below thresholds.
