AAC Block Project By HIL Limited

Integrity

The project document supports additionality through a barrier test, and that assessment was confirmed by the VVB. FPIC and a grievance mechanism are also documented, which strengthens the safeguards side of integrity. On the other hand, leakage is only described as quantified without the actual deduction rate, and buffer pool coverage or reversal events are not stated in the available record.

Transparency

Transparency is limited by missing operational and registry details. The extracted record does not identify the VVB, does not provide verified issuance or claimed-versus-verified error figures, and does not state the usage monitoring method. The monitoring and crediting periods are clear, but the overall MRV picture remains incomplete.

Claim Safety

Claim safety is moderate because the project uses a recognized VCS methodology and a project-specific baseline, but the evidence base is thin on over-crediting controls. The record does not state verified error reductions, leakage deduction percentage, or usage-rate evidence, so the risk of overstated claims cannot be ruled out. CORSIA eligibility and CCP status are not stated, which adds uncertainty rather than reassurance.

Documentation

Documentation quality is middling: three documents were used, and the extracted PDD reports no material findings or corrective actions. Still, extraction confidence is only medium, and one evidence document is unidentified, which reduces confidence in completeness. The project document is dated 2017, so the evidence is not especially recent relative to the full crediting period.

Overall

The project shows a credible additionality narrative and some safeguard documentation, but the evidence is too incomplete to rate it highly. There are no explicit contradictions in the extracted record, so no document had to be privileged over another; instead, the main issue is missing data, especially around leakage, permanence, and issuance verification. Because several key fields are not stated, the score is held to a mid-range level rather than a stronger one.
