Double Materiality
Double materiality is a whole-of-value-chain exercise. Engage affected and informed stakeholders where impacts occur—upstream producers, logistics partners, contract manufacturers, workers in your own and suppliers' operations, communities, customers, and end-users. Combine dialogue (surveys, interviews, grievance channels) with data (audits, incidents, science-based thresholds) to ground judgements. Refresh the assessment periodically or when triggers occur (new markets, M&A, regulatory shifts, major incidents). The result is a single, decision-useful picture of impacts, risks, and opportunities across the full value chain and over short, medium, and long time horizons.
Capture inside-out impacts and outside-in financial effects across your value chain with ESRS-grade rigor.
Double materiality is the CSRD/ESRS lens that looks both ways at once. Why it matters. This dual perspective elevates sustainability to the same discipline as financial reporting: it exposes real-world impacts, surfaces financially relevant risks and opportunities, and aligns strategy, risk, and capital allocation with credible transition pathways. It requires companies to assess (and report on) sustainability impacts on people and planet (inside-out, impact materiality) and financial effects on the business arising from sustainability matters (outside-in, financial materiality).
Define organizational and value-chain boundaries (upstream/downstream), reporting time horizons, and entities in scope. Align with ESRS concepts and governance.
Start from ESRS topical matters; add sector-specific and entity-specific issues (operations, products, geographies). Map dependencies (natural, human, social capital).
Collect signals from internal and external stakeholders (employees, suppliers, customers, communities, investors, NGOs, regulators). Compile incident data, peer benchmarks, science, and legal drivers.
Assess materiality—two lenses
Impact materiality (inside-out): score scale, scope, irremediability and likelihood of actual/potential impacts
Financial materiality (outside-in): assess magnitude and probability of effects on cash flows, cost of capital, or access to finance.
For each material topic, map required ESRS datapoints, metrics, and targets; connect to governance, strategy, risk management, and metrics/targets.
Record methods, criteria, data sources, judgements, and governance. Prepare for limited assurance (and future reasonable assurance) with traceable evidence trails.
Materiality register & matrix: the final list of material topics with impact/financial flags, severity/likelihood scoring, and value-chain location. IROs linkage: a clear register of Impacts, Risks, and Opportunities for each topic, with responsible owners and time horizons. ESRS mapping: a table showing which disclosures are in scope (and why), data availability, estimation methods, and planned improvements. Narrative coherence: explain methods, thresholds, stakeholder engagement, and constraints. Tie outcomes to targets, action plans, capital expenditure (CapEx) plans, and transition milestones. If a topic is not material: state the rationale; for climate specifically, include the required forward-looking analysis. Disclose these elements in the sustainability statements of the annual report, consistent with ESRS structure and with controls comparable to financial reporting.
