Against the sources it cites
When a figure cites a standard, a certificate or a study published online, Velydian opens it and checks the figure against it.
Coming soon
Coming soon · For sustainability and ESG teams
The figure in the report, tied to the data behind it.
A sustainability report states a scope total, a baseline year and a reduction. Velydian for sustainability reporting is built to tie each stated figure to the table it came from and to recompute what can be recomputed.

VerdictIllustration
CLAIM IN YOUR REPORTNeeds Revision
“Our Scope 1 and 2 emissions have fallen by 30% since 2019.”
What the source says
Emissions table: baseline year 2020, 48,200 t CO2e; 2025, 37,600 t CO2e (−22%).
Report annex, emissions table
The report’s own table shows a 22% fall from a 2020 baseline, not 30% since 2019.
The stakes
What an unsupported claim costs.
53%
Green claims in the EU that give vague, misleading or unfounded information. 40% have no supporting evidence at all.
European Commission, Green claims$19M
SEC penalty on DWS for misleading statements about its ESG investment process.
US SEC press release 2023-194 (Sep 2023)A$12.9M
Record greenwashing penalty for Vanguard Australia: a bond fund claimed exclusions that most of its holdings were never screened for.
ASIC 24-213MR (2024)A$11.3M
Penalty for Mercer: “Sustainable Plus” options marketed as excluding fossil fuels, alcohol and gambling held companies in all three.
ASIC 24-173MR (2024)What it catches
Six things that go wrong in reports.
Each one with the claim, the passage Velydian reads, and the verdict. Examples for illustration.
A reduction that does not compute
“Emissions have fallen by 30% since 2019.”
Table: 2020 baseline 48,200 t; 2025 37,600 t: −22%.Needs Revision
The report’s own table gives 22%, from a different baseline.
A scope total that does not add up
“Total Scope 1 and 2: 12,400 t CO2e.”
Scope 1: 7,900 t; Scope 2: 5,300 t. Sum: 13,200 t.Needs Revision
The parts do not add up to the stated total.
A claim broader than the certificate
“All our electricity is renewable.”
Certificates cover Swiss sites only.Needs Revision
Sites abroad are not covered.
A target read as a commitment validated by others
“Our net-zero target is externally validated.”
No validation record for the company could be found.Unverifiable
Flagged before it becomes a greenwashing claim.
A vague claim with no basis
“Our packaging is eco-friendly.”
No supporting data in the report or its annexes.Not Supported
Exactly the kind of claim EU authorities flag.
A figure tied to its table
“Water withdrawal was 1.2 million m³ in 2025.”
Table 7: water withdrawal 2025: 1.2 million m³.Supported
Matches the report’s own table.
Not another fact checker
Not just right or wrong. Supported or not.
Velydian checks the figures. It also weighs what a report does with them: the explanation it gives and how strongly it states it. A reduction can be right and the sentence around it can still mislead readers and assurers.
One claim, three levels · illustration
“Our switch to renewable power cut emissions by 22%.”Needs RevisionSource: the report’s own emissions annex. Example for illustration.
- Level 1
Facts
Totals, baselines, reductions and scopes, checked against the data behind them.
Does the table say 22% or 12%?
Velydian findsSupportedThe 22% fall is in the report’s own emissions table.A citation check stops here: true. - Level 2
Interpretation
Whether a conclusion follows from the source, or reaches further than it.
Did the switch do this, or something else?
Velydian findsStretchedThe annex shows most of the fall came from closing one plant, not from the power switch. - Level 3
Judgement
Whether the statement is as strong as its evidence, and what was left out.
Would an assurer see the whole picture?
Velydian findsOverstatedThe headline does not say which emissions fell. The 22% covers Scope 1 and 2; Scope 3 in the same annex rose 9%.Verdict: Needs Revision. The figure is right; the explanation reaches further than the data allows.
How it works
Upload the report. Every figure comes back with its evidence.
PDF, Word, text or Markdown, or paste it in. Velydian finds each figure and claim and checks it in one of three ways.
Against your own data
Attach the emissions inventory, the certificates or the supplier data, and every figure is checked against them. You see the price before it starts.
Claims with no source
Velydian searches official websites, research databases and the wider web, keeps the strongest sources and checks the claim against them.
Three layers of checking
Surface tools check that a source exists. Velydian reads it.
Layer 1
Distortions and inaccuracies
Totals that do not add up, baselines that move, a scope quietly narrowed.
A baseline year moved from 2019 to 2020 without a note.
Layer 2
Bias and fabrication
Claims the data does not support, vague claims with nothing behind them, and what was left out.
The metric that fell is headlined; the one that rose stays in the annex.
Layer 3
Stronger sources
When a figure rests on a summary, Velydian looks for the data or certificate itself.
A press article is flagged, with the certificate offered instead.
One verdict per claim
Four verdicts, each with its evidence.
Supported
The data checked backs the figure as written.
Needs Revision
Close, but a total, the baseline or the scope does not match the data.
Not Supported
The data does not back the claim, or says something different.
Unverifiable
No data could be read or found that settles it, for example an inventory you did not attach.
Open any verdict to see the passage and the reasoning behind it. Correct a line or swap a source and it is checked again. Velydian weighs the evidence; your team decides what to change.

Early access
We run your first report with you.
The sustainability layer is built and not yet switched on. Early-access firms send one report; we run it with them and they decide whether to go further. Nothing is charged for that first run.
The general engine works on any document today: every claim checked against the sources it cites, sources it finds, or your own files.
Questions
Before your first report.
What works today?
The general engine checks any report against its sources or your own files today. The sustainability layer, which recomputes totals and reductions, is built and not yet switched on.
How do we get early access?
Request early access below. We run your first report with you, and you decide whether to go further.
Does it replace assurance?
No. It does the tracing and gives your assurance provider an audit trail to start from. The assurance opinion stays with them.
Where do the sources come from?
Three places. The sources your document cites; sources Velydian finds on official websites, research databases and the wider web for claims without a citation; or your own files, if you attach them.
What happens to my document?
When you run a check, your document’s text is sent over an encrypted connection to our servers and AI services in Switzerland and the EU. To find evidence, short search queries built from your claims are sent to web and scholarly search services. Your document’s content and results are deleted automatically about 24 hours after your check; source links and summary data are kept.
Which languages does it check?
English is measured and in daily use. German and French are in validation.
Can I rely on Velydian as my only check?
Velydian supports human review. It shows the evidence behind every verdict so you can decide. In high-stakes work, expert judgement stays essential.
