Most carbon tools give you a number. VerityOS gives you the number and the chain of proof behind it, from source bill to AI extraction to pinned factor to the human who approved it. Built in Singapore, for Singapore’s ISSB reporting reality, and the same engine ships a second report: your ISO/IEC 42001-aligned AI-governance record, included in every tier.
AI reads it. You approve it. The vault remembers it. The AI does the data entry; a named human makes the call.
The AI does the heavy lifting. You stay in control of every figure that carries your name.
Upload a utility bill, invoice, or fuel receipt: PDF, scan, or photo. No templates, no manual re-typing.
The AI extracts each value (kWh, litres, dates, supplier) and shows you a confidence score beside each one, so you know exactly where to look first.
Nothing is trusted until a named person signs off. You review, correct if needed, and approve. That is the human-in-the-loop that makes the number defensible.
Once approved, the record is hash-chained into an append-only evidence vault. It can be added to, never quietly altered, so the source behind every figure is always there to show.
The moment your data is in, VerityOS applies the emission factors and calculates your Scope 1 and Scope 2 totals automatically. No spreadsheets, no formulas to maintain.
Out comes an IFRS S2-aligned report and an assurance-ready evidence pack (the figures, the source documents, and the approval trail), so when someone independent checks, everything lines up.
Reporting usually begins with someone re-typing utility figures into a spreadsheet: slow, and impossible to audit later. VerityOS starts one step earlier: ingest the actual bill and let the AI read it, with a confidence score on every field so you know precisely where to look.
AI reads; people decide. Between extraction and your books sits a mandatory review gate, and nothing writes itself into the record. Every figure carries the name of the person who approved it, which is exactly what an assurer wants to see.
This is the part no other carbon tool has. Your data lives in an append-only, hash-chained vault. You don’t edit an entry; you post a reversal, so the full history stays intact and tamper-evident. When a period is finalised, it locks and freezes.
prev genesis → 3af2…91bcprev 3af2…91bc → 7f3a…c2e1prev 7f3a…c2e1 → b2c8…44daBuild a structured report aligned to IFRS S2, with an AI-drafted narrative you approve section by section. Your Scope 1+2 figures are computed directly from the vault (never typed in), so the report and the evidence can never drift apart.
Go beyond 1+2 with a Scope 3 starter covering the categories most SMEs can actually measure, then set reduction targets and track your decarbonisation trajectory against what the vault says really happened.
A live dashboard turns the vault into insight: filter by scope, source and year, spot your hotspots, and track year-on-year movement, so the reporting exercise doubles as a reduction roadmap.
VerityOS speaks the frameworks assurers and regulators expect, and it never holds your data hostage. Generate the assurance pack in one click, and export your data in whatever format you need.
For firms delivering ESG reporting at scale, the workbench runs many clients from one place, with strict tenant isolation enforced in the database, not just the interface. Singapore-region hosting and a PDPA erasure path come standard.
isolated workspace · row-level securityisolated workspace · row-level securityisolated workspace · row-level securityEverything above produces your sustainability disclosure. The same evidence vault also runs an ISO/IEC 42001-aligned AI Data Governance workspace, included in every tier, so the one pipeline carries two conformity stories.
Overall conformance percentage, progress by control objective, and the governance evidence captured on every AI extraction: model, prompt version, confidence, and the named human approver.
Every AI system in the organisation on the record: purpose, owner, risk context. The inventory an ISO/IEC 42001 audit starts from.
The full 65-control catalogue: 27 management-system clauses plus 38 Annex A controls, tracked per control with status, owner, and linked evidence.
Structured impact assessments for consequential AI systems, stored as first-class records beside the emission evidence.
Bring a single utility bill. We’ll show you the whole chain (extraction, review, vault entry, and the tonne that comes out the other side) in one sitting. Thirty minutes now beats reconstructing a year of bills the month before the assurer arrives.
Every number, traceable to its bill.
