AAC Blocks project by Mohit Industries Limited
Score Breakdown
Integrity
verified Additionality was confirmed by the VVB using a barrier test, which supports the project case.
missing The verified emission reductions are much lower than the claimed figure, and leakage treatment is not quantified in the extracted record.
Transparency
verified The monitoring report is recent and names RINA as the VVB, with a defined monitoring period from 2021-09-01 to 2022-11-24.
missing Key MRV details are missing, including the usage monitoring method, verified usage rate, and leakage deduction.
Claim Safety
verified The project is not CORSIA-eligible, which reduces one channel of double-claim exposure.
missing The gap between claimed and verified emission reductions, together with a project-specific baseline and missing leakage quantification, increases over-crediting risk.
Documentation
verified The record draws on multiple official document types and includes 33 documents used, with high extraction confidence.
missing The monitoring report lists several corrective action requests, including incomplete documentation of monitoring data and emission-reduction calculations.
Detailed Analysis
Integrity
The project has a positive signal from the VVB-confirmed barrier additionality test, and the validation record reports no reversal events. However, the baseline is project-specific rather than a standardized or recently reassessed baseline, and leakage deduction is not quantified in the extracted record. The large difference between claimed and verified emission reductions also weakens confidence in the robustness of the credited volume.
Transparency
The documentation identifies RINA as the VVB and provides a clear monitoring period, which helps traceability. Even so, the extracted record does not state the usage monitoring method, verified usage rate, or leakage deduction, all of which are important for assessing MRV quality. The monitoring report also shows several corrective action requests, indicating that parts of the documentation needed improvement.
Claim Safety
Claim safety is weakened by the substantial gap between the claimed emission reductions and the verified amount in the validation records. The project is not CORSIA-eligible, which helps reduce one form of dual-claim risk, but the absence of quantified leakage treatment and the use of a project-specific baseline leave over-crediting concerns unresolved. No CCP status is stated in the available record, so that channel cannot be treated as a positive safeguard.
Documentation
The evidence base is reasonably broad, with 33 documents used and high extraction confidence, which supports the documentation score. At the same time, the monitoring report records four corrective action requests and notes incomplete transparency around monitoring equipment and emission-reduction estimation. The crediting period is long and the monitoring period is recent, but several key fields remain unstated in the available documents.
Overall
The project is supported by some credible process evidence, especially VVB-confirmed additionality and a recent monitoring report, but the quality of the credited claim is constrained by missing MRV detail and a large claimed-versus-verified gap. I privileged the more recent monitoring report for safeguards and monitoring-period facts, while using the validation report for verified emission reductions because it is the more specific source for issuance quantities. The contradictions mainly show that earlier documents were superseded or incomplete, but they still reduce reliability and justify a conservative score.
Audit Analysis
This project has some procedural support, including VVB-confirmed additionality and no reported reversals, but the evidence base is uneven and several key quantities are unclear. The large gap between claimed and verified emission reductions, plus missing leakage and usage-monitoring details, raises meaningful over-crediting and claim-quality concerns.
Project Description
Proponent: Big Bloc Construction Limited Protocol categories: Manufacturing industries Protocols: AMS-III.Z Estimated annual GHG reductions: 21917 tCO2e Region: Asia Registration date: 2020-04-06
Red Flags
- Verified emission reductions are far below the claimed amount, with 42,373 verified versus 181,635 claimed in the validation records.
- Leakage deduction, buffer pool contribution, and usage monitoring method are not stated in the extracted record.

Cosa migliorerebbe questo punteggio
- Publish a complete leakage assessment and any deduction applied, along with the usage monitoring method and verified usage rate.
- Resolve the documentation gaps flagged by the CARs and provide a clear reconciliation of claimed versus verified emission reductions.
Questi suggerimenti indicano quali prove pubbliche aggiuntive potrebbero migliorare il livello di confidenza di questa valutazione. Non garantiscono un punteggio futuro più alto.
