Score Breakdown

Integrity

verified The verification report (2025-11-17) confirms additionality using an investment test.

missing Baseline method and leakage treatment were not found in the extracted record, weakening confidence in the quantified removal claim.

Transparency

verified A specific monitoring period is stated (2023-11-01 to 2024-09-30) and a VVB is identified (EnergyLink Services).

missing Claimed vs verified removals were not found in the extracted record, and multiple corrective actions are listed in the verification report (2025-11-17).

Claim Safety

verified The project is explicitly not CORSIA-eligible, reducing certain double-claiming/eligibility marketing risks.

missing CCP status is not stated in available documents and key quantification items (baseline/leakage/verified ERR) were not found in the extracted record, increasing over-crediting and greenwashing risk.

Documentation

verified The extracted record references 12 documents and includes a recent verification report dated 2025-11-17.

missing Evidence document labeling is weak (listed as "unknown"), and safeguards information is inconsistent across documents.

Detailed Analysis

Integrity

The verification report (2025-11-17) confirms additionality via an investment test, which supports additionality robustness. However, the baseline method and the timing of any baseline reassessment were not found in the extracted record, limiting confidence that credited removals are conservatively quantified. Leakage treatment (deduction and justification) was also not found in the extracted record, and the verification report lists corrective actions (including natural gas consumption and distance to end users) that could be integrity-relevant if they affect net removals.

Transparency

The extracted record provides a clear monitoring period (2023-11-01 to 2024-09-30) and identifies the VVB as EnergyLink Services, which helps traceability. No material findings are reported in the verification report (2025-11-17), but the same report still lists corrective actions required (distance to end users, natural gas consumption, and a CORC report summary), suggesting some reporting gaps that reduce MRV clarity. Claimed and verified total removals were not found in the extracted record, which materially limits public transparency of outcomes.

Claim Safety

The project is explicitly not CORSIA-eligible, which reduces the risk of certain high-profile eligibility-based marketing claims. However, CCP status is not stated in available documents, and the extracted record lacks key quantitative substantiation items (baseline method, leakage treatment, and total verified removals), increasing the risk that public claims could overstate certainty. The presence of corrective actions in the verification report (2025-11-17) also suggests that some claim-critical inputs may have required follow-up or clarification.

Documentation

The extracted record indicates 12 documents were used and includes a recent verification report dated 2025-11-17, supporting reasonable documentation coverage and recency. Minimum extraction confidence is medium, implying some limitations but not a severe readability failure. Evidence document identifiers are weak (evidence docs listed as "unknown"), and safeguards-related fields are incomplete (no FPIC, no grievance mechanism, and no benefit sharing described), which reduces documentation completeness for social safeguards.

Overall

Overall scoring is moderated by strong additionality confirmation in the verification report (2025-11-17) but weakened by missing baseline, leakage, and verified removal totals in the extracted record. The safeguards contradiction is material: safeguards are indicated as mentioned in a 2025-11-17 record but not mentioned in a 2023-04-28 record; I privilege the more recent verification record for whether safeguards are mentioned, but the inconsistency still reduces confidence and lowers transparency/documentation scores. No material findings are reported, yet multiple corrective actions are required in the 2025-11-17 verification report; I treat this as a reliability signal (issues existed even if not classified as material), warranting a conservative overall score.

Audit Analysis

This Puro biochar removal project has VVB-confirmed additionality and a stated buffer contribution, but key quantification elements (baseline approach, leakage treatment, and verified removals) were not found in the extracted record. The latest verification report reports no material findings, yet still lists multiple corrective actions, which raises some MRV reliability questions. Safeguards information is inconsistent across documents, increasing reputational and claim risk.

Project Description

Oregon Biochar produces a high-quality, high-carbon and high surface area biochar (Rogue Biochar) from local forestry biomass available in the NorthWest USA. Our production facility, which has been operational for over 30 years, is a carbon-neutral biomass plant located in Jackson County, Oregon. Our feedstocks include low-value biomasses recovered from farms and orchards, woody biomass and burnt material from forest fires as well as secondary and tertiary wood residues from the region. Our biochar has an 83% fixed carbon content and a 0.08 H/C and 0.05 O/C molar ratios as well as a high surface area allowing it to compete and displace fossil and unsustainably produced activated carbons in key application such as water filtration. About 80% of our production is sold in agriculture, where its soil water and nutrient retention, structure and microbial benefits provide farmers with an added-value solution to diverse issues, such as low-water availability, drought, nutrient run-off, poor soil and compaction. About 15% of our production is used in stormwater management applications, preventing nutrient and pollutant run offs to water bodies, while the rest is applied in industrial water filtration for AC replacement. Oregon Biochar’s goal is to drawdown carbon, mitigate climate change, decrease water pollution and regenerate severely degraded lands. But we can’t do it alone. Part of the solution, our solution, to these complex goals is biochar.

Red Flags

Baseline approach and reassessment timing were not found in the extracted record, limiting confidence in over-crediting controls for a removal project.
Leakage deduction and justification were not found in the extracted record, despite potential transport/energy-related leakage relevance for biochar supply chains.
Verified removals (total verified ERR) were not found in the extracted record, reducing transparency and claim substantiation.
Safeguards are contradictory across documents (mentioned in a 2025-11-17 verification record but not mentioned in a 2023-04-28 record).

Cosa migliorerebbe questo punteggio

Disclose and clearly summarize the baseline approach and any reassessment schedule in the public project documentation, aligned to the Puro biochar methodology version v3.1.
Publish quantified leakage treatment (deduction percentage and justification), including transport distances and energy use (e.g., natural gas consumption), and report claimed vs verified removals for the monitoring period.
