Audit-ready carbon management software · Singapore

Every number,
traceable to its bill.

VerityOS is carbon management software built in Singapore for SMEs: AI reads the bills, a person approves every number, and a hash-chained vault keeps the proof — one vault carrying both your ISSB-aligned sustainability disclosure and your AI data governance record. Built for the FY2029 assurance mandate, when “trust me” stops being an answer.

The status quo

Singapore’s climate numbers live in Excel.

Scope 1+2 reporting has been mandatory for every SGX-listed company since FY2025. External assurance arrives FY2029. Most reporting stacks haven’t changed since neither was true.

Only about half of respondents use any digital tool for their sustainability reporting.

42%

Say even their external service providers lack the expertise to help.

7%

Use no digital tools at all — the report is manual, end to end.

Schneider Electric × SGX RegCo survey, January 2026 — 543 executives, 76% at SGX-listed companies.

When the assurer asks “show me where this number came from,” Excel has no answer.
How it works

From bills to assurable disclosure.

01

Drop the bills

Utility bills, fuel invoices, receipts — PDF or photo. Every file is stored untouched, as evidence.

02

AI reads, a person approves

Every extracted field carries a confidence score, and a named approver signs off each number. Nothing writes itself into your report.

03

The vault takes over

Approved entries join an append-only, hash-chained ledger. Corrections are visible reversals — history is never rewritten.

04

One click to assurance

Export the IFRS S2 disclosure draft and the assurance pack — every figure linked back to its bill, its extraction record, and its approver.

AI reads it. You approve it. The vault remembers it. From a photo of a bill to a Scope 1+2 number — the AI handles the middle, and a named human makes the call.

Watch a report build itself
The vault

Built the way an auditor reads.

Most tools give you a number. VerityOS gives you the number and the trail an assurer will actually test — source document, extraction record, pinned emission factor, named approver — by construction, not by discipline.

Append-only, hash-chained

Every entry carries the hash of the one before it. Tamper anywhere and the chain breaks — visibly.

Reversals, not edits

Mistakes are corrected with an offsetting entry, like a financial ledger. Corrections stay visible — exactly what an assurer wants to see.

Final reports freeze

Finalise a report and its period locks in the database. The number you filed is the number that stays.

Emission factors pinned

Each entry pins the exact factor version used, so the calculation can be reproduced years later.

VerityOS can’t stop a client lying to you. It makes it impossible to lie quietly.

The AI reads. A person decides. The database remembers who. How we govern the AI

What’s inside

Every tonne you report, traceable to the bill it came from.

VerityOS runs the full Singapore Scope 1+2 reporting workflow — capture, review, vault, report, export — so that when the assurer arrives in FY2029, your numbers already have their receipts. AI-assisted, human-approved, hash-chained — that’s why the number holds.

Read any bill

Drop in a utility bill or fuel invoice as a PDF or photo. The AI reads every field and gives you a confidence score, so you always know what to double-check.

Nothing writes itself

A human review gate sits between extraction and your books. Every figure is approved by a named person before it becomes a number in your report.

The evidence vault

An append-only, hash-chained record of everything. You never edit history — you post a reversal. At report freeze, the vault's fingerprint is handed to you and independently timestamped — tamper-evident against everyone, including us.

Pinned emission factors

Every calculation is tied to a specific, versioned emission factor. Re-run the same period next year and you'll see exactly which factor produced which tonne.

IFRS S2 report builder

Build a structured, ISSB-aligned report with an AI-drafted narrative you approve section by section. Scope 1+2 is computed from the vault — never typed by hand.

Targets & trajectory

Set reduction targets and watch your decarbonisation path plotted against real vault actuals, not aspirations.

The assurance pack

Export a single ZIP — register, evidence, hashes — that answers the assurer's first question before they ask it: “show me where this number comes from.”

Your data, your formats

Export to CSV, XLSX, XML or TSV whenever you want. The evidence is always yours to take.

One vault, two reports

The vault that proves your emissions also governs your AI.

Buying VerityOS is buying two conformity stories, not one. The same evidence engine that carries your sustainability disclosure runs an AI Data Governance workspace aligned to ISO/IEC 42001 — the world’s first certifiable AI-management standard, adopted in Singapore. Included in every tier:

  • A registry of every AI system in your organisation
  • A 65-control Statement of Applicability — status, owner, and linked evidence per control
  • Structured AI impact assessments, kept beside the emission evidence
  • A live conformance dashboard — model, prompt version, confidence, and the named approver on every AI extraction

Explore AI Data Governance

Pricing

Three ways in. One evidence standard.

Quoted and contracted annually, in SGD — the rhythm of a reporting year. Every tier includes the AI Data Governance workspace: two conformity reports for the one price.

“Priced like the incumbents’ calculators. Built for the FY2029 audit their spreadsheets won’t survive — every number traceable to its bill.

Government support for your first report

Government support can cover a meaningful share of your first ISSB-aligned report. Larger and SGX-listed companies claim via the Sustainability Reporting Grant — up to 30% of qualifying costs, capped at S$150,000. Eligible SMEs are served by the SME Sustainability Reporting Programme(up to 50%, through EnterpriseSG-appointed providers). Eligibility and rates are set by EnterpriseSG, which assesses every application — the claim is your company’s, lodged before any contract is signed or work begins, and we never promise an outcome.

For consultancies & accounting firms

Your delivery engine, not another licence.

42% of reporting companies say their external providers lack the expertise to help (SGX RegCo × Schneider, Jan 2026). That’s your opening — if you can show up with evidence, not a spreadsheet. A firm serving ten clients on single-company tools buys ten licences and still stitches the trail together by hand. The Workbench is one place: every client a strictly isolated workspace, every number assurance-ready, all of it under your delivery and your fee.

Questions

Honest answers, on the record.

Is my client data isolated?

Yes. Every client organisation is a separate workspace, and isolation is enforced with row-level security in the database itself — not just in application code. Data is hosted in the Singapore region.

Couldn't VerityOS itself tamper with the vault?

Not without being caught — and we engineered it that way on purpose. A hash chain inside a database its operator controls is only tamper-evident against everyone below the operator, so we close that gap by pushing the proof outside the system: when a report is finalized, the vault's chain-head fingerprint is printed in your report (your copy, outside our control) and timestamped by an independent RFC 3161 Time-Stamp Authority. Rewriting history after that would produce a vault that no longer matches the fingerprint you hold and a neutral third party notarised. Tamper-evidence that holds against everyone — including us.

Can VerityOS stop someone feeding it bad numbers?

No — and no software can. What VerityOS does is make it impossible to lie quietly: every number links to a source document, an extraction record, a pinned emission factor, and a named approver, and every correction is a visible reversal. If a client hands you a bad bill, the bad bill is on the record — and so is who approved it.

What about Scope 3?

A deliberate starter, not a guess factory. VerityOS covers the four Scope 3 categories an SME can actually evidence — water, waste, business travel, and employee commuting — with published DEFRA 2025 factors, reported separately from your assurable Scope 1+2 core. You can also set reduction targets and track the decarbonisation pathway against vault actuals. What we still refuse to ship is the other eleven categories as estimates nobody can defend.

Is VerityOS eligible for government support on my first report?

It depends on who you are. Larger and SGX-listed companies can use the Sustainability Reporting Grant (SRG) — up to 30% of qualifying costs (software, consultancy, assurance, training) for a first ISSB-aligned report, capped at S$150,000. The SRG is only for SGX-listed companies or those with annual revenue of at least S$100 million, so ordinary SMEs do not qualify for it. Eligible SMEs are served instead by the SME Sustainability Reporting Programme through EnterpriseSG-appointed providers — up to 50% co-funding (as of 1 April 2026). In every case the claim belongs to the company, is lodged with EnterpriseSG before any contract is signed or work begins, and eligibility and approval are decided solely by EnterpriseSG. We structure our quotes with clean, claimable line items — but we never promise approval.

Can I export everything?

Yes — that is the product. The assurance pack contains every emission entry, its source document, the hash chain, and the pinned emission-factor versions. The emission register also exports directly to CSV, Excel (XLSX), XML, and TSV. There is no lock-in by hostage-taking: your evidence is always yours to take.

Who's behind VerityOS?

VerityOS was created by Freemansland Creatives Pte. Ltd., a Singapore branding and marketing consultancy focused on digital transformation and science-based evidence logging. Behind it is a team of consultants and practitioners in sustainability and data protection — certified management consultants (PMC) and ACLP-certified trainers. The engine was built delivering a real sustainability-reporting engagement for a national charity in Singapore.
