Score Breakdown

Integrity

verified The validation documentation indicates an investment-test additionality approach, and no material findings or corrective actions were reported in the validation report.

missing Baseline approach, leakage treatment, buffer/reversal provisions, and any verified removal quantities were not found in the extracted record.

Transparency

verified Two core documents (PDD and validation report) are present in the extracted set.

missing Monitoring period, VVB identity, and claimed-versus-verified removal totals were not found in the extracted record.

Claim Safety

verified Safeguards are mentioned and FPIC is indicated in the extracted record.

missing CORSIA/CCP status and key quantification inputs (baseline and leakage) were not found, increasing greenwashing/over-crediting risk.

Documentation

verified The extracted set includes a PDD and a validation report, and extraction confidence is medium.

missing Document date, VVB name, monitoring/crediting period details, and several core quantification fields were not found in the extracted record.

Detailed Analysis

Integrity

The extracted record shows an investment-test additionality argument, but it is not clear from the extracted data whether the VVB explicitly confirmed additionality in the validation report. For ERW, integrity hinges on the baseline and quantification approach, yet no baseline method or reassessment timing is captured from the PDD/validation report. Leakage and permanence-related provisions are also not evidenced in the extracted record (no leakage deduction/justification, no buffer pool percentage, and no reversal reporting), which materially weakens confidence in the robustness of credited removals.

Transparency

Transparency is limited because the extracted record does not include a monitoring period, any claimed removals, or any verified removals, so readers cannot reconcile what was monitored versus what was credited. The VVB name is also not captured, reducing traceability of independent assurance. While the PDD and validation report are present, the absence of key MRV fields in the extracted record constrains public auditability.

Claim Safety

Claim safety is weakened by the lack of extracted evidence on the baseline method and leakage treatment, both of which are central drivers of over-crediting risk in ERW. The extracted record does indicate safeguards are mentioned and that FPIC was conducted, which helps reduce social-risk-related greenwashing. However, CORSIA eligibility and CCP status are not found in the extracted record, leaving uncertainty about how credits might be marketed and whether additional eligibility claims could be made.

Documentation

Documentation completeness is moderate: only two document types (PDD and validation report) are in the extracted set, and the document date is not captured. Extraction confidence is medium, which supports some reliance on the record but still suggests potential missing details. The absence of key fields (VVB name, monitoring/crediting period, baseline/leakage quantifications) indicates either gaps in the underlying documents or incomplete extraction, both of which reduce documentation quality for due diligence.

Overall

Overall quality appears below average because the extracted record lacks the core quantitative and assurance elements needed to evaluate ERW removals (baseline approach, leakage treatment, monitoring period, and claimed vs verified totals). There are no listed contradictions in the extracted record, so the main issue is evidence gaps rather than conflicting statements. Note: if documentation were scored below 3.0, transparency would be capped by the gate rule; and if integrity were below 4.0, the overall score would be capped at 6.0—these caps are applied after scoring.

Audit Analysis

The extracted record indicates an investment-test additionality argument and mentions safeguards with FPIC, but key quantifications needed to judge ERW credit integrity (baseline approach, leakage treatment, monitoring period, and verified removals) are not present. With only a validation report and PDD available in the extracted set and no verification/issuance figures captured, the risk of over-crediting cannot be confidently ruled out.

Project Description

Project Name : UNDO Basalt Enhanced Rock Weathering Project Location : Canada Developer : UNDO Impact : Permanent removal of CO2, increased crop yield for agricultural partners, and significant co-benefits for the environment and local communities. Why this project needs your support : The UNDO Basalt Enhanced Rock Weathering Project aims to revolutionize carbon dioxide removal efforts while enhancing agricultural productivity. By harnessing the power of basalt, a silicate with low trace metal levels, UNDO delivers impactful CO2 removal while simultaneously increasing crop yields for agricultural partners by up to 16%. Selected by Microsoft in 2023 for its pioneering approach, UNDO has developed efficient and accurate infrastructure to scale enhanced rock weathering globally. Key Features of the Project : 1. Scalable, Peer-Reviewed Science: UNDO employs a scientifically rigorous MRV (Measurement, Reporting, and Verification) approach, utilizing extensively peer-reviewed one-dimensional transport models with proprietary enhancements. This approach accurately models the carbon dioxide removal of specific operations globally, ensuring precision through local data inputs and field-adjacent techniques. 2. High-Quality Project Data: UNDO utilizes its proprietary 'Newton' data platform to collect real-time project data across global operations. This platform enables accurate tracking of operational data from quarry to field, including GPS-tracked haulage and spreading operations. 'Newton' ensures 100% data traceability, linking rock mineralogy results to specific spreading volumes and locations. 3. Scalable Operations: UNDO has established a global network of quarry partners, where basalt by-products are sourced and tested for suitability. This supply chain is connected to approved agricultural partners, facilitating the efficient spreading of basalt using existing farming machinery. The operational partner model ensures the 24/7 tr

Red Flags

No baseline method or baseline reassessment timing found in the extracted record, which is central to ERW removal quantification.
No leakage deduction or leakage justification found in the extracted record.
No monitoring period and no claimed vs verified removal totals found, limiting MRV transparency and over-crediting risk assessment.
No VVB name and no confirmation that additionality was verified by the VVB found in the extracted record.

Cosa migliorerebbe questo punteggio

Provide (or extract) the ERW quantification details from the PDD/methodology: baseline approach, leakage sources and any deduction, and how uncertainty is handled.
Add the monitoring/verification package and registry issuance data: monitoring period, claimed vs verified removals, VVB identity, and any non-conformities/corrective actions.
