Why double materiality matters
The double materiality assessment is the foundation of your entire CSRD report. It determines which ESRS topics you must disclose and, by extension, which datapoints you need to collect.
Get it right, and you’ll focus your reporting effort on what truly matters. Get it wrong, and you risk either over-reporting (wasting resources) or under-reporting (facing regulatory scrutiny).
The two dimensions
Impact materiality
Impact materiality looks outward: how does your company affect people and the environment? This includes:
- Direct operations (Scope 1 and 2 emissions, workplace safety)
- Value chain impacts (supplier labour practices, product end-of-life)
- Both actual impacts (happening now) and potential impacts (could happen)
Financial materiality
Financial materiality looks inward: how do sustainability issues create risks or opportunities for your company? Consider:
- Physical risks (climate events disrupting operations)
- Transition risks (carbon pricing, shifting regulations)
- Opportunities (new markets, cost savings from efficiency)
Step-by-step process
1. Map your stakeholders
Identify internal and external stakeholders who can inform your assessment:
- Internal: Board members, department heads, sustainability team, workers’ representatives
- External: Investors, customers, suppliers, regulators, local communities, NGOs
2. Create your long list of topics
Start with all ESRS topics (E1–E5, S1–S4, G1) and their sub-topics. For each, gather evidence of potential materiality from:
- Industry benchmarks and peer reports
- Regulatory landscape analysis
- Internal risk registers
- Stakeholder feedback and surveys
3. Score and prioritise
Rate each topic on both dimensions using a consistent scoring methodology:
- Impact: Severity (scale, scope, irremediability) × likelihood
- Financial: Magnitude of financial effect × likelihood
4. Set thresholds and select material topics
Define clear thresholds for what constitutes “material” on each dimension. A topic is material if it meets the threshold on either dimension , you don’t need both.
5. Document and validate
Your assessment methodology, scoring criteria, and stakeholder engagement process must all be documented. This documentation will be reviewed by your auditor.
Common pitfalls
- Skipping stakeholder engagement: Regulators expect genuine consultation, not just a desktop exercise
- Confusing materiality dimensions: Impact and financial materiality are assessed separately
- Setting thresholds too high: This risks excluding topics that should be reported
- Not involving leadership: The board must understand and approve the final topic selection
