Score Breakdown

Integrity

verified The verification report (2025-12-18) confirms additionality using an investment test and reports no material findings or corrective actions.

missing Baseline method and baseline reassessment timing are not stated in the extracted record, and leakage is not clearly treated (no deduction and inconsistent justification).

Transparency

verified A VVB is identified (350Solutions, Inc.) and a specific monitoring period is provided (2025-10-01 to 2025-11-30).

missing Key public-accounting elements are unclear or inconsistent, including conflicting ERR figures and missing baseline/leakage details; extraction confidence is low.

Claim Safety

verified Claimed and verified removals match within the 2025-12-18 verification record (29,475.74), suggesting internal consistency in that document.

missing Contradictory ERR totals across documents (29,475.74 vs 42,631) and missing baseline/leakage quantification increase over-crediting and greenwashing risk; CORSIA/CCP status is not stated.

Documentation

verified The extracted record includes a dated verification report (2025-12-18) and indicates 12 documents were used.

missing Evidence document naming is not provided (listed as "unknown") and minimum extraction confidence is low, indicating documentation usability/traceability issues.

Detailed Analysis

Integrity

The verification report (2025-12-18) confirms additionality via an investment test and reports no material findings and no corrective actions, which supports procedural integrity. Permanence risk is described as unlikely and no reversals are reported in the extracted verification record, but there is no buffer pool percentage stated in the extracted record, limiting confidence in long-term risk management. Baseline validity cannot be assessed because the baseline method and any baseline reassessment date are not stated in the extracted record. Leakage is a major gap: the extracted record shows leakage is not addressed and provides no leakage deduction, and other documents contradict this by calling leakage negligible.

Transparency

The extracted record identifies the VVB (350Solutions, Inc.), provides a monitoring period (2025-10-01—2025-11-30), and includes a dated verification report (2025-12-18). However, transparency is weakened by conflicting removals totals across documents and by missing core MRV descriptors such as the baseline method and any usage monitoring method in the extracted record. The evidence document list is not traceable (listed as "unknown"), and the minimum extraction confidence is low, suggesting at least one key source was hard to read and increasing uncertainty in the extracted dataset.

Claim Safety

Within the 2025-12-18 verification record, claimed and verified removals are the same (29,475.74), which would normally reduce over-crediting concerns for that specific issuance. But a separate document dated 2025-11-27 reports a much higher figure (42,631) for both claimed and verified removals, creating a material risk that public claims could reference the higher number. Baseline and leakage are not adequately evidenced in the extracted record (baseline method not stated; leakage not addressed/no deduction), which increases the risk that credited removals are overstated. CORSIA eligibility and CCP status are not stated in the extracted record, leaving uncertainty about how credits might be marketed and perceived.

Documentation

The extracted record indicates 12 documents were used and includes a recent verification report date (2025-12-18), which is a positive for recency. However, the evidence document identifiers are not provided (shown as "unknown"), limiting auditability and third-party traceability. Minimum extraction confidence is low, meaning at least one key document was poorly readable; this reduces confidence in the completeness and accuracy of extracted facts. Contradictions across documents on core fields (ERR totals and safeguards items) further indicate documentation control/versioning issues.

Overall

This project shows some strengths (VVB-confirmed additionality and no reported reversals in the 2025-12-18 verification record), but the extracted record has major reliability and completeness gaps around baseline and leakage. Contradiction 1 and 6 (ERR claimed/verified of 29,475.74 vs 42,631) are material; I privilege 29,475.74 because it is tied to the later-dated verification report (2025-12-18), but the existence of a near-contemporaneous higher figure (2025-11-27) lowers confidence and scores. For leakage, I privilege the more conservative statement "not addressed" over "deemed negligible" because it implies weaker substantiation and aligns with the absence of any leakage deduction in the extracted record. For safeguards (safeguards mentioned; grievance mechanism; benefit sharing; FPIC), I privilege the more recent 2025 documents where they indicate safeguards are missing (no grievance mechanism, no benefit sharing, no FPIC), and I score down due to the inconsistency with the 2023 document claims.

Audit Analysis

The project has some integrity positives, including VVB-confirmed additionality via an investment test and no reported reversals in the verification record. However, key baseline and leakage elements are missing or inconsistently reported across documents, and multiple contradictions (including the verified removals figure) materially weaken confidence in the credited outcome.

Project Description

PUR-353054 — Geologic Sequestration

Red Flags

  • Verified and claimed removals conflict across documents (29,475.74 vs 42,631), creating over-crediting risk.
  • Baseline approach is not stated in the extracted record, limiting assessment of baseline validity and conservativeness.
  • Leakage treatment is inconsistent across documents ("not addressed" vs "deemed negligible") and no leakage deduction is provided.
  • Safeguards and stakeholder provisions are contradictory (FPIC, grievance mechanism, benefit sharing), increasing social integrity uncertainty.
  • Low extraction confidence indicates at least one key document was poorly readable, reducing reliability of extracted facts.

Cosa migliorerebbe questo punteggio

  • Publish and clearly reference the baseline approach (including assumptions, data sources, and any reassessment schedule) in the verification/monitoring package and registry entry.
  • Provide a consistent, documented leakage assessment (quantified or justified negligible) and apply an explicit leakage deduction where appropriate, with the same conclusion across all project documents.
  • Resolve and publicly clarify the ERR discrepancy (29,475.74 vs 42,631) with version control and an issuance/verification reconciliation note.

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