The product

An evidence engine for Scope 1+2 reporting.

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.

How it works

Watch a report build itself — with you approving every number.

The AI does the heavy lifting. You stay in control of every figure that carries your name.

1

Drop the bill.

Upload a utility bill, invoice, or fuel receipt — PDF, scan, or photo. No templates, no manual re-typing.

2
Confidence scores

AI reads every field.

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.

3
Human decides

You approve.

Nothing is trusted until a named person signs off. You review, correct if needed, and approve — the human-in-the-loop that makes the number defensible.

4

It’s locked into the vault.

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.

5

Scope 1+2 computes itself.

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.

6

The report and assurance pack generate.

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.

01Capture & Extract

Start with the bill, not the spreadsheet.

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.

  • Ingest utility bills and fuel invoices as PDF or photo
  • AI extraction with a per-field confidence score
  • The original document stays attached as source evidence
  • No manual re-keying of consumption figures

02Human Review

A human approves every number. Always.

AI reads; people decide. Between extraction and your books sits a mandatory review gate — 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.

  • Mandatory human review before anything is committed
  • Named-approver audit trail on every entry
  • Low-confidence fields flagged for a closer look
  • Clear separation between “the AI suggested” and “a person approved”

03The Vault

History you can’t quietly rewrite.

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.

  • Append-only, hash-chained evidence record
  • Reversals instead of silent edits — nothing disappears
  • Reporting periods that lock and freeze on finalisation
  • Every entry cryptographically linked to the one before it

04The IFRS S2 Report

A report the assurer can follow.

Build 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.

  • Structured IFRS S2 report builder
  • AI-drafted narrative, approved per section
  • Scope 1+2 computed from the vault, not entered by hand
  • GRI 305 and SGX (ISSB) framework crosswalk built in

05Scope 3 & Targets

Start Scope 3, and steer toward your targets.

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.

  • Scope 3 starter: water, waste, business travel, employee commuting
  • Built on DEFRA 2025 emission factors
  • Reduction targets with a plotted decarbonisation trajectory
  • Progress measured against vault actuals, not estimates

06Dashboard & Insights

See where your emissions actually come from.

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.

  • Four-chart dashboard with Scope / Source / Year filters
  • Emission hotspot identification
  • Year-on-year comparison
  • Every chart traceable back to its source entries

07Frameworks & Export

Reported to standard, exported on demand.

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.

  • ISO 14064-1 and GHG Protocol methodology
  • GRI 305 + SGX (ISSB) crosswalk in the report
  • Assurance pack export (ZIP: register, evidence, hashes)
  • Multi-format data export: CSV, XLSX, XML, TSV

08Consultant Workbench

One engine, every client, cleanly separated.

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.

  • Multi-client workbench from a single login
  • Strict tenant isolation via database row-level security
  • Singapore-region hosting
  • PDPA erasure path built in

Also in the product — one vault, two reports

The AI Data Governance workspace.

Everything 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.

Overview

Live conformance dashboard

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.

Systems

AI system registry

Every AI system in the organisation on the record — purpose, owner, risk context. The inventory an ISO/IEC 42001 audit starts from.

Controls

Statement of Applicability

The full 65-control catalogue — 27 management-system clauses plus 38 Annex A controls — tracked per control with status, owner, and linked evidence.

Impact

AI impact assessments

Structured impact assessments for consequential AI systems, stored as first-class records beside the emission evidence.

Explore AI Data Governance

See it run

See it run on one of your own bills.

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.
