Top-Down Double Materiality Assessment Under Revised ESRS: Practical Methodology

The revised ESRS introduce an explicit top-down route to avoid unnecessary work. The purpose is to begin with evidence about the undertaking and focus detailed assessment where it can change the conclusion. It is not permission to replace the ESRS criteria with a management brainstorm, a peer list or a sector template.

A robust top-down process can reach conclusions at topic or sub-topic level when materiality or non-materiality is evident. If the conclusion is not evident, or if a more granular assessment could reasonably lead to a different result, the undertaking performs a focused IRO assessment. It can combine this route with bottom-up analysis for specific topics.

Workshop voting can help surface disagreement, but it does not determine materiality. The facilitator should record the evidence, reasoning and unresolved challenge. Seniority should not replace the criteria, and affected-stakeholder evidence should not be converted into a popularity score.

Using top-down only for negative conclusions while requiring exhaustive evidence for material topics, creating an asymmetric methodology.

Failing to distinguish evident non-materiality from an uncertain conclusion that needs focused assessment.

Applying one group-wide geography level when basin, ecosystem, region or site context can change impact severity.

Ignoring existing due-diligence, grievance and risk-management evidence because it was not created for the DMA.

Letting workshop consensus override severe-impact evidence or external expert findings.

Documenting only final topics and losing the trace from business-model evidence to the conclusion.

Assuming that a proportionate process requires no annual change review. Significant changes must still be considered at each reporting date.
