Double Materiality Assessment (DMA) & IROs

The DMA converts regulatory text into a company-specific list of Impacts, Risks and Opportunities (IROs). Everything that follows—gap analysis, strategy, data controls—depends on the integrity of this list.

Outputs you will produce:

·       a board-approved DMA methodology note

·       a scored matrix of material IROs, linked to value-chain segments and stakeholders

·       a short narrative explaining threshold choices and scoring scales

·       an annual refresh plan anchored in the corporate calendar

1.     Governance‑validated DMA methodology – no workshops before the process is ratified.

Secure board or steering-committee sign-off on the process before workshops begin. Attach a short slide that fixes scope, decision rules, and validation checkpoints to prevent any dispute.

2. Appoint topic-wise manager squads (carbon, waste, social, governance, procurement, etc.) and assign operational ownership, backed by top-management 

Create four multi-disciplinary teams, one squad per pillar. Each squad receives a “playbook” containing background data, stakeholder lists and a workshop agenda

3.     Set a clear scope for what part of the value chain is being assessed

Begin with activities and stakeholders for which reliable data already exist (typically Tier-1 suppliers, own operations and direct customers). Plan to deepen coverage in subsequent reporting cycles.

4.     Secure management-validated time budgets so scoring isn’t rushed.

Agree on an amount of hours that teams will use towards the DMA. Have HR and managers include it in workload planning.

5. Describe the generating facts behind every IRO to make qualification robust.

Capture the generating fact in one sentence (e.g., “Upstream mining activities”). It allows the identification of the ESG consequences of activities, stream and processes, resulting in a robust qualification of IROs. This root-cause tag will also allow you to cluster related IROs when prioritizing actions.

6.     Set an “awareness” threshold beneath materiality to trigger knowledge building on emerging IROs.

Any IRO landing just below the materiality cut-off enters an Emerging-Watchlist. Assign a knowledge-building action owner so weak signals are not lost.

7.     Use dedicated scoring scales for E, S, G topics to keep evaluations consistent.

Provide at least three 1-to-5 tables (Environmental, Social, Governance). Make the definitions explicit (e.g. Environmental Impact 5 = irreversible ecosystem loss or > €25 m remediation cost).

8.     Run structured stakeholder workshops in every topic stream.

Limit sessions to half a day and 12 informed participants. A neutral facilitator walks the group through identification, scoring and clustering; photos of voting system go straight into the audit log.

9.     Deliver a complete DMA matrix

Deliverables material topics list, value-chain map, stakeholder overlay.

10.  Update DMA annually to reflect evolving risks/opportunities (≥ FY cadence).

Bake the review into the corporate calendar: Q1 IRO review → Q2 DMA refresh → Q3 policy alignment.
