Score Breakdown

Integrity

verified Additionality confirmed by the validator in the validation report (2025-08-18)

missing Reversal treatment not addressed and multiple corrective actions/FARs remain open, undermining permanence

Transparency

verified VVB named (Earthood Services Limited) and monitoring period provided (2023-01-01 — 2024-12-31)

missing Key MRV numbers missing or not extracted: total emissions claimed/verified not found; extraction confidence rated low

Claim Safety

verified A leakage deduction of 5% is recorded in recent documents (2023) which partially mitigates over-crediting risk

missing Conflicting values for usage rate (95% vs 90%), FNRB (0.85 vs 0.97) and leakage (5% vs 0%) across documents indicating risk of inconsistent baseline/crediting calculations

Documentation

verified A large document set was used (35 documents) and a validation report dated 2025-08-18 is available

missing Min extraction confidence is low and evidence documents are listed as unknown, reducing confidence in the extracted record

Detailed Analysis

Integrity

Additionality is confirmed by the validator in the validation report (2025-08-18), and the baseline is documented as project-based with a reassessment in 2024, supporting baseline validity. However, reversal events are listed as not addressed in the latest material and the buffer pool percentage is not stated, and several corrective actions and forward action requests remain open (listed in the validation report), which weakens permanence. Leakage has a reported deduction of 5% in one document (2023) but the justification is noted as not addressed in the latest report (2025), creating uncertainty about leakage treatment.

Transparency

The verification/validation body is named (Earthood Services Limited) and the monitoring period (2023-01-01 — 2024-12-31) is provided. The registry is Gold Standard and grievance/FPIC/safeguards are mentioned, which improves traceability. However, key quantitative MRV fields such as total emissions claimed and verified are not found in the extracted record, and the minimum extraction confidence is low, reducing transparency of reported numbers.

Claim Safety

There is partial mitigation of over-crediting risk: a 5% leakage deduction and a locally measured FNRB value (0.85) are present in recent documents. But contradictions exist across documents: earlier records show a higher FNRB (0.97), an earlier usage assumption of 90%, and earlier leakage treatment of 0%. These inconsistencies between document versions increase the risk that crediting calculations could be overstated or inconsistently applied.

Documentation

The extraction used 35 documents and includes a validation report dated 2025-08-18, which is recent. Nevertheless, evidence documents are labeled unknown and the min extraction confidence is low, indicating at least one poorly readable source. Multiple corrective actions and FARs were raised (some converted and some still open), which indicates active issues that require resolution before high confidence can be placed in the documentation.

Overall

I privileged the more recent values where contradictions exist because later validation/monitoring documents typically supersede older ones: for benefit sharing I privileged 'described' from 2025-08-18 over an earlier false record (2023-04-14); for reversal events I privileged the more recent 'not addressed' (2025-08-18) over an earlier 'none reported' (2024-12-13) because the later document indicates newly identified gaps; for usage rate I privileged 95% from 2024-10-02 over the older 90% from 2018 since monitoring updates are more current; for leakage I privileged the 5% deduction recorded in 2023 over the older 0% in 2020, but note the latest 2025 report says justification is not addressed; for FNRB I used the local field value 0.85 recorded more recently (2023) over the older national default 0.97 (2020); and for crediting period I privileged the 2025–2030 period in the 2025 validation report over the earlier 2013–2020 period. These contradictions and the low extraction confidence reduce trust in the dataset and have been factored into lower transparency, claim safety and documentation scores.

Audit Analysis

The project shows some positive governance: a VVB-confirmed additionality and a recent baseline reassessment (2024). However, important gaps and contradictions remain (leakage justification, reversal treatment, inconsistent usage and FNRB values) and extraction confidence is low, reducing reliability of claims.

Project Description

Developer: CO2balance UK ltd Type: Energy Efficiency - Domestic Size: Micro Scale Crediting period: 2017-11-04 → 2024-11-03 Estimated annual credits: 10000 tCO2e SDGs: Goal 6: Clean Water and Sanitation, Goal 5: Gender Equality, Goal 13: Climate Action, Goal 3: Good Health and Well-Being

Red Flags

  • Leakage justification not addressed in the latest report despite a leakage deduction being reported
  • Reversal events not addressed and buffer pool not stated while forward action requests remain open

Cosa migliorerebbe questo punteggio

  • Publish clear leakage justification and reconciliation of historical leakage percentages (address the contradiction between 5% and 0%)
  • Provide transparent MRV tables including total emissions claimed and verified, buffer pool percentage, and close outstanding FARs with evidence in the next verification

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