Evidence, not assertion.

What Data-Trust means

A sustainability number on its own is a claim. The same number with its source, its review history and a clear statement of how well it is supported is evidence. Data-Trust is our name for that difference.

Every figure that passes through EcoVeraZ carries a Data-Trust Score — a transparent confidence indicator that reflects the strength of the source, whether the figure has been reviewed, and whether it agrees with independent references. A whole report can carry a Data-Trust Certificate™, which records that the evidence chain behind it is intact and has not been altered since it was prepared.

Why evidence beats assertion

Financial reporting settled this question decades ago. A figure in an audited statement sits on a chain of source documents, controls and independent review, and anyone with the right access can follow that chain. Sustainability reporting mostly has not caught up: numbers arrive from spreadsheets, supplier emails and estimates, and the trail behind them is reconstructed — if at all — when someone asks.

Our approach is to keep the trail attached from the start. Data is drawn from the systems that produce it. Each figure keeps its source, its status and its reviewer as it moves toward a report. The result is that the question "where did this come from?" is answered before it is asked.

How a number becomes defensible

Four things happen to a figure between the meter and the board paper. None of them requires the reader to understand how the platform is built.

• Recorded. The figure is captured from its source — a meter, a fuel log, an ERP entry, a supplier declaration, a document — and the source type is kept with it: measured, reported, estimated, or sensor-backed.
• Reviewed. A person confirms it, or marks it for attention. Figures that have not been reviewed say so.
• Cross-checked. The figure is compared with its own history and with independent references. A reading that does not fit is flagged rather than passed through.
• Presented with its trail. The board sees the summary; the auditor opens the trail; the framework disclosure carries the figure with its confidence signal. All three come from the same record.

Frameworks we map to

Four framework pages show, for BRSR / BRSR Core, CSRD / ESRS, ISSB and the GHG Protocol, what each asks for, what evidence supports it, a worked example, and what EcoVeraZ has in place today.

Evidence is collected once and prepared for the disclosures that need it. EcoVeraZ maps evidence to the statutory and voluntary frameworks below, prepares product-level data for Digital Product Passport requirements as they arrive, and uses the GHG Protocol as the accounting basis for emissions figures. Mapping means the evidence is organised for a framework's questions; it does not mean EcoVeraZ validates, certifies or files against it — that remains with your organisation and your appointed third parties.

What EcoVeraZ is — and is not

We work beneath the professionals and authorities who verify, assure and regulate. Being clear about that boundary is part of the approach.

Demonstrations on this site run on synthetic, deterministic data across three fictional facilities. No customer is described, and the figures shown are representative rather than results.

Because these boundaries are easy to blur, there is a page that draws them against the four things EcoVeraZ is most often taken for — rating agencies, carbon accounting software, reporting suites and assurance firms: how EcoVeraZ differs. What an engagement then looks like in practice is on how we work, with three pilot shapes showing what comes out of one.
