Score Breakdown

Integrity

verified Additionality was confirmed by the VVB using an investment test, which supports the project case.

missing Leakage justification is not addressed, and reversal treatment is also not addressed in the extracted record.

Transparency

verified The monitoring period is stated for 2023-01-01 to 2024-12-31, and the VVB is named as Earthood Services Limited.

missing Total issued and verified ER figures are not found in the extracted record, and the monitoring approach still needs clearer downtime and survey transparency.

Claim Safety

verified The baseline was reassessed in 2024, which is better than an outdated baseline with no update.

missing The project is marked CORSIA-eligible, while CCP status is not stated, and the record contains unresolved contradictions on FNRB, usage rate, and leakage.

Documentation

verified A relatively large number of documents were used, and safeguards such as FPIC and a grievance mechanism are documented.

missing Extraction confidence is low, and the verification record lists many closed clarifications and corrective actions, indicating documentation gaps.

Detailed Analysis

Integrity

The project has a positive integrity signal because the VVB confirmed additionality through an investment test. That said, leakage is recorded as 0% while the justification is not addressed, and reversal events are also not addressed in the available documents. The baseline is project-based rather than clearly standardized, which is weaker than a recently reassessed jurisdictional baseline.

Transparency

Transparency is limited by missing core issuance data: total claimed and verified ER figures are not found in the extracted record. The monitoring period is stated, the VVB is identified, and the baseline was reassessed in 2024, but the corrective actions show that future reports still need clearer downtime reporting and more transparent survey design. Low extraction confidence further reduces confidence in the completeness of the documentation.

Claim Safety

Claim safety is weakened by the combination of CORSIA eligibility and no stated CCP status, which leaves dual-claim risk unresolved. The record also shows contradictions on FNRB method, FNRB value, usage rate, leakage justification, and crediting period; I privileged the newer 2025 validation report for the current values because it is the most recent document, but the contradictions still reduce reliability. The project’s 0% leakage deduction without a supporting explanation is another over-crediting concern.

Documentation

Documentation breadth is moderate because 34 documents were used and safeguards like FPIC, benefit sharing, and a grievance mechanism are mentioned. However, the extraction confidence is low, and the validation report lists many closed clarifications and corrective actions, which suggests the record is not fully clean or easy to audit. The crediting period is also inconsistent across documents, which further weakens documentation quality.

Overall

I privileged the most recent validation report dated 2025-08-18 for conflicting items such as reversal treatment, leakage justification, FNRB method/value, usage rate, and crediting period because it is the latest and appears to be the highest-priority synthesis document. Even so, the contradictions remain material and should lower confidence because they show the record is not internally consistent. The project is not a clear red flag on additionality, but the unresolved leakage, dual-claim, and documentation issues keep the overall assessment modest. The integrity score is above the gate threshold, so no post-score cap is triggered.

Audit Analysis

The project has some positive signs, including VVB-confirmed additionality and documented safeguards such as FPIC and a grievance mechanism. However, reliability is weakened by low extraction confidence, multiple unresolved contradictions, and several key items that are not addressed, especially leakage justification and reversal treatment. The claim profile is therefore cautious rather than strong.

Project Description

Developer: CO2balance UK ltd Type: Energy Efficiency - Domestic Size: Micro scale Methodology: GS TPDDTEC v 1. Crediting period: 2017-05-05 → 2024-05-04 Estimated annual credits: 10000 tCO2e SDGs: Goal 6: Clean Water and Sanitation, Goal 13: Climate Action, Goal 5: Gender Equality, Goal 3: Good Health and Well-Being

Red Flags

  • Leakage is set at 0% but the justification is not addressed in the available record.
  • Several material findings and corrective actions were raised, and the record shows low extraction confidence with multiple contradictions across documents.

Cosa migliorerebbe questo punteggio

  • Provide a clear, document-backed explanation for the 0% leakage deduction and reconcile the conflicting leakage statements across reports.
  • Publish a clean reconciliation of the contradictory FNRB, usage rate, and crediting-period values, with a single authoritative source for each.

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