Score Breakdown

Integrity

verified The verification report confirms additionality using an investment test.

missing Permanence controls (buffer pool or reversal provisions) and leakage treatment are not found in the extracted record.

Transparency

verified A named VVB (EnergyLink Services) and a defined monitoring period (2023-08-02 to 2024-03-31) are provided in the verification report.

missing Key MRV outputs (claimed vs verified removals) are not found in the extracted record, limiting auditability.

Claim Safety

missing Corrective actions on LCA inputs and CORC calculation formulas in the verification report increase over-crediting/greenwashing risk until resolved.

inferred CORSIA eligibility and CCP status are not stated in available documents, leaving uncertainty on downstream claim constraints.

Documentation

verified The extracted record references a recent verification report dated 2025-11-04 and indicates six documents were used.

missing Evidence document labeling is weak (evidence docs listed as "unknown") and extraction confidence is only medium.

Detailed Analysis

Integrity

The verification report (2025-11-04) confirms additionality via an investment test, which supports the case that the project is not business-as-usual. However, the baseline is described only as project-specific and the timing of any baseline reassessment is not stated in available documents, which weakens robustness. For a biochar removal project, permanence management details such as a buffer pool percentage and any reversal events are not found in the extracted record, and leakage deduction/justification is also not found, creating material integrity uncertainty.

Transparency

The verification report identifies the VVB as EnergyLink Services and provides a clear monitoring period (2023-08-02 to 2024-03-31). At the same time, the extracted record does not include the total removals claimed or verified, so an external reviewer cannot reconcile issuance quantities to monitoring data. The presence of multiple corrective actions in the verification report suggests that some underlying data and calculations were not yet presented in a fully transparent, verification-ready form.

Claim Safety

Claim safety is constrained by missing quantitative outputs (no verified total removals found in the extracted record) and missing leakage treatment, both of which are central to assessing over-crediting risk. The verification report’s corrective actions on LCA inputs, CORC calculation formulas, total biochar sold, and moisture content indicate that key parameters affecting credited removals required fixes, increasing the risk of overstated claims until closed out. CORSIA eligibility and CCP status are not stated in available documents, so buyers may face uncertainty about how credits can be used and represented.

Documentation

Documentation is moderately strong in that a recent verification report (2025-11-04) is present and the extraction indicates six documents were used. However, the evidence document list is not specific (listed as "unknown"), which reduces traceability to primary sources. The minimum extraction confidence is medium, implying some limitations in document readability or extraction quality that should temper reliance on the extracted fields.

Overall

No contradictions were identified in the extracted record, so scores are not adjusted for cross-document discrepancies. The project benefits from VVB-confirmed additionality and a recent verification, but the absence of key quantified results (verified removals) and missing leakage/permanence controls in the extracted record materially limit confidence. The number and nature of corrective actions in the verification report point to unresolved MRV/calculation weaknesses, keeping overall quality in the mid range; note that if integrity were to fall below 4.0, an overall cap would apply under the gate rules.

Audit Analysis

This Puro.earth biochar removal project has additionality confirmed by the VVB and no material findings reported, but key quantitative elements needed to judge over-crediting risk (verified removals, leakage treatment, permanence/buffer approach) are not present in the extracted record. Multiple corrective actions in the verification report indicate MRV and calculation controls still need strengthening before claims can be considered low-risk.

Project Description

ECOERA is a Swedish biochar innovation company awarded the WWF Climate Solver company label. They have been in the biochar field for over ten years and in 2009 created Sweden’s first large scale biochar carbon sequestration in agricultural fields. They were part of developing the Biochar Carbon Offset Methodology and specifically the Biochar Carbon Stability Test Method under the International Biochar Initiative. The biochar is produced from residue biomass streams from agricultural seed production. Residues that would otherwise be wasted or decompose. Each ton of biochar is 70% pure carbon and embodies 2,57 tonnes of CO2e, while manufacturing it emits only 0,05 tonnes of CO2e. For a detailed carbon footprint description email [email protected] The Ecoera mission is to be part of removing carbon dioxide from the atmosphere at an industrial capacity, with the aim to reach pre-industrial levels of 350 ppm CO2 before the end of the century, while making the agricultural land fertile enough to feed 10 billion people on this planet. How it works The pyrolysis process is a way to condense the CO2 from the biomass and stabilize it into biochar for hundreds of years. The carbon stability in the biochar is 3rd party verified through being compliant with the standards of the European Biochar Certificate (EBC) and the Puro.earth Biochar methodology. The facility in Hammenhög, the foundation for ECOERA Millennium 1 is producing EBC certified biochar and the heat generated is supplied to a district heating grid. The system is possible to be replicated at many new sites. The carbon removal purchases enable and accelerate their work to establish a new biochar production site and support sustainable agriculture using biochar as a soil amendment. The location for the biochar production system is 55.506702, 14.154831.

Red Flags

Verified removal volume is not found in the extracted record (no verified total removals reported).
Leakage treatment (deduction and justification) is not found in the extracted record.
Verification report requires corrective actions on LCA inputs, CORC calculation formulas, and total biochar sold, indicating elevated quantification risk.

Cosa migliorerebbe questo punteggio

Publish and/or extract the verified total removals for the monitoring period, with a clear reconciliation from feedstock inputs through CORC calculations to issued credits.
Provide explicit leakage assessment (justification and any deduction) and permanence risk management details (e.g., buffer pool contribution and reversal handling) in accessible project documentation.
Close out the verification report corrective actions by documenting corrected LCA inputs, CORC formulas, metered electricity data (not nominal), moisture content measurement, and independently verifiable sales/usage records for biochar.
