UNDO trial enhanced rock weathering project in Canada

Integrity

No project design or assurance documents were available in the extracted record, so additionality testing, baseline selection, leakage treatment, and permanence/reversal provisions cannot be confirmed. With no monitoring or verification report evidence, there is no basis to assess whether credited removals/avoidance are conservative. The absence of any stated buffer, reversal events, or leakage deductions should be treated as an evidence gap rather than a positive finding.

Transparency

Transparency is very weak because no documents were available to confirm the VVB, monitoring period, MRV methods, or any verified results. The extracted record provides no ERR claimed versus verified figures, no uncertainty treatment, and no registry completeness indicators beyond the registry code. Low extraction confidence further reduces confidence that missing items are merely absent rather than unreadable.

Claim Safety

Claim safety is low because the extracted record does not include baseline methodology, monitoring approach, or any third-party verification outcomes that would bound over-crediting risk. Eligibility/status indicators relevant to claim risk (such as CORSIA eligibility or CCP status) were not found in the extracted record, so double-claim risk cannot be screened. Given the lack of substantiation, any public claims would be difficult to defend.

Documentation

Documentation is effectively absent: the extracted record lists zero evidence documents and zero documents used. Minimum extraction confidence is low, indicating at least one key source was poorly readable, which further undermines completeness and reliability. Without core documents (PDD, monitoring report, verification report), the project cannot be assessed against standard quality expectations.

Overall

No contradictions were reported, but this is not meaningful because there are no underlying documents in the extracted record to compare. Scores are therefore driven primarily by missing evidence and low extraction confidence, which together indicate high uncertainty and elevated quality risk. Note: under the stated gate rules, a documentation score below 3.0 would cap transparency post-scoring.
