The evidence engine for sustainability reporting

Every number,
traceable to its bill.

AI reads the bills. A person approves every number. A hash-chained vault keeps the proof. ISSB-aligned Scope 1+2 reporting, 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.

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.

Sustainability Reporting Grant (SRG)

Companies preparing their first ISSB-based report may claim up to 30% support on qualifying costs — including software subscriptions and consultancy — under EnterpriseSG’s SRG. The application is yours, lodged before any contract is signed or work begins, and eligibility and approval are decided solely by EnterpriseSG. Your claim to make; never ours to promise.

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.

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?

Deliberately not yet. VerityOS is evidence-first: Scope 1+2 is what is mandatory for all SGX-listed companies from FY2025 and what assurance will test from FY2029. Scope 3 estimates without evidence behind them are the industry's problem, not our product. We'd rather do the assurable core properly than ship a wider number nobody can defend.

Is VerityOS eligible for the Sustainability Reporting Grant?

SRG qualifying costs include software subscriptions and consultancy for a company's first ISSB-based report, with support of up to 30%. The claim belongs to the reporting company, the application must be lodged with EnterpriseSG before any contract is signed or work begins, and eligibility and approval are determined 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. There is no lock-in by hostage-taking: your evidence is always yours to take.

Who's behind VerityOS?

VerityOS is built and delivered by Freemansland, a Singapore consultancy led by a PMC-certified (Practicing Management Consultant) consultant. The engine was built delivering a sustainability-reporting engagement for a national charity in Singapore.
