What this public verifier proves

Certified entity: SustainPro Dubai event workspace
Certified period: Q1 2026
Method boundary: GHG Protocol-style Scope 1/2/3 calculation summary
How to challenge it: If any ID, footprint, evidence count, lifecycle state, or issuer seal changes, this page shows validation failed/not matching.

Sealed footprint: Footprint is shown in the sealed packet details.
Evidence source types: Direct meter/source 1 · Staff meter photo 1 · Invoice/manual support 1
Public result: Record matched

Direct meter/source: meter, connector, or authoritative source record. Non-live readings are labeled.

Staff meter photo: staff photo or field reading tied to a receipt.

Invoice/manual support: invoice, manual, or estimate input that may need supporting files.

Sealed means locked

SustainPro sealed the footprint and evidence references into a platform record. Any changed sealed certificate ID, footprint, evidence count, or registry reference breaks this public match.

Arabic and English views show the same sealed record.

External use is allowed only within the reviewer-approved scope. Excluded activity categories, source-pending or proxy factors, baseline/target claims, wider sites, benchmarks, green claims, filings, and assurance statements remain outside this public verifier unless the reviewer packet explicitly accepts them.

What this is not

This page proves the public record still matches SustainPro's sealed registry. It does not certify emissions performance, replace reviewer source-file approval, or create a regulatory filing by itself.

What to do

This is not the current buyer packet. Ask for the current verifier before external reliance.

Can I rely on this today?

No, sample only.

This is a product sample. It is not issued to a buyer and cannot support a claim.

Buyer: this is a draft verifier; external claims are not approved yet.

Issuer: send the reviewer packet and source files before sponsor, filing, benchmark, or green-claim use.

Reviewer: approval unlocks the stated external-use scope.
