ESRS·Decision guide·Assurance and controls
The ESRS sustainability statement should be a clearly identified, dedicated section of the management report. Under the revised ESRS (Delegated Regulation (EU) 2026/1563), it is normally organised into four parts: general information, environmental information, social information and governance information.
Helps you decideDistinguish the dedicated statement, its four parts and the four reporting areas.

ESRS·Explainer·Assurance and controls
The most damaging ESRS mistakes are rarely isolated missing sentences. They are control failures that begin earlier: the wrong legal or reporting perimeter, an outdated standard, a checklist-style materiality assessment, value-chain evidence that was never requested, generic policies presented as mature management responses, unsupported estimates, financial effects disconnected from finance, weak cross-references and uncontrolled final files.

ESRS·Explainer·Assurance and controls
ESRS does not require one universal survey or a separate engagement exercise solely for the double materiality assessment. Affected-stakeholder evidence is a key input to impact materiality and can come from ongoing due diligence, direct engagement, legitimate representatives, credible proxies, users and experts.
Helps you decideHow to design proportionate engagement and prove its influence on decisions.

ESRS·Decision guide·Assurance and controls
A first ESRS cycle should be run as a controlled 15-month reporting transformation, not as a sustainability-writing project. The critical path is: confirm legal scope and standard edition; establish governance; complete a defensible double materiality assessment; lock reporting and metric boundaries; build the data dictionary and evidence model; perform dry-run calculations; draft and review disclosures; operate internal controls; complete assurance; obtain board approval; publish; and remediate findings.
Helps you decideWhat must be decided early, which workstreams can overlap, and which dependencies sit on the critical path?

Preparing an ESRS sustainability statement is a controlled reporting programme, not a late-stage writing exercise. The undertaking first locks the legal scope, reporting entity, reporting period and applicable ESRS version.
Helps you decideHow to organise the programme so that materiality, data, narrative, controls and publication form one traceable process.

ESRS·Decision guide·Assurance and controls
An ESRS sustainability statement is ready for limited assurance when the undertaking can reconstruct how material impacts, risks and opportunities were identified; explain the reporting boundaries and estimates used; trace each material metric and narrative claim to controlled evidence; demonstrate the link between policies, actions, resources, targets and results; and show who prepared, reviewed, challenged and approved the information. Readiness does not mean that assurance has been obtained.
Helps you decideDefine limited-assurance readiness without treating readiness work as an assurance conclusion.

The internal ESRS disclosure matrix is a control and assurance tool; the public list of DRs required by IRO-2, which may be presented as a content index, is a reader-navigation output. The matrix should link each material IRO and topic to the relevant DRs, mandatory ARs and atomic datapoints, then to owners, evidence, methodology, controls, assurance status, drafting location and final page.
Helps you decideWhich fields and workflow are needed from IRO to final page.
