Double Materiality, simplified for 2026.
The complete guide to the Double Materiality Assessment under the Simplified ESRS, Directive (EU) 2026/47 and EFRAG Implementation Guidance 1. For enterprises preparing for Wave 2 CSRD reporting and SMEs aligning to the Voluntary SME Standard.
The undertaking’s effect on people and the environment
Impact materiality relates to the actual and potential impacts — positive and negative — that the undertaking has on the environment and on people, including workers, value-chain actors, affected communities and consumers. It is assessed regardless of whether those impacts create financial consequences for the undertaking itself.
Under ESRS 1, impacts are assessed across the undertaking’s own operations and its upstream and downstream value chain. Where a potential negative human rights impact is identified, severity takes precedence over likelihood.
- Scale
- How grave is the impact on people or the environment.
- Scope
- How widespread the impact is — number of people affected or breadth of environmental damage.
- Irremediability
- How difficult it is to remediate or reverse the harm.
- Likelihood
- For potential impacts only — the probability of the impact occurring.
Sustainability effects on the undertaking
Financial materiality addresses the sustainability matters that trigger, or could reasonably be expected to trigger, financial effects on the undertaking — its development, performance, position, cost of capital or access to finance, in the short, medium or long term.
This lens aligns with the IFRS S1 / ISSB concept of materiality, enabling interoperability. A sustainability matter may give rise to risks that erode value, or opportunities that create it.
- Magnitude
- The size of the financial effect on the undertaking’s performance or position.
- Likelihood
- The probability that the financial effect will materialise.
- Time horizon
- Short-term (≤ 1 year), medium-term (1–5 years), long-term (> 5 years).
- Dependency
- Reliance on natural, human or social resources at appropriate price and quality.
The combined lens
A sustainability matter is material to the undertaking when it meets the criteria for impact materiality, financial materiality, or both. The DMA process identifies material matters across both lenses, with the outcome determining which ESRS disclosure requirements apply.
Under the Simplified ESRS, materiality operates as an overarching filter: only material information is disclosed. The fair presentation principle governs the sustainability statement as a whole.
- Either threshold
- Impact OR financial materiality is sufficient.
- Interaction
- Impact-material matters often become financially material over time, and vice versa.
- Proportionality
- Reasonable and supportable information available without undue cost or effort, per Simplified ESRS 1.
- Fair presentation
- The assessment must produce a complete, neutral and accurate depiction of material IROs.
Where we are, where we’re going.
The regulatory architecture for double materiality has moved rapidly through 2025 and into 2026. The timeline below tracks every material milestone from the original CSRD through to the expected delegated act adoption.
CSRD enters into force
Directive (EU) 2022/2464 makes the double materiality assessment a legal requirement for in-scope undertakings.
ESRS Set 1 adopted
Commission Delegated Regulation (EU) 2023/2772 adopts the first set of European Sustainability Reporting Standards.
EFRAG IG 1 published
EFRAG Implementation Guidance 1 — Materiality Assessment — provides the authoritative illustrative DMA process.
Omnibus I package proposed
Commission proposes the “Omnibus” simplification package (COM(2025) 80 and 81) to amend the CSRD, CSDDD and EU Taxonomy.
ESRS exposure drafts

ESRS, ISSB, GRI, SASB.
Double materiality is a feature of the European standards. Other frameworks take different approaches. The comparison below clarifies what each requires, and how they interoperate.
| Criterion | ESRS (EU) | IFRS S1/S2 (ISSB) | GRI | SASB |
|---|---|---|---|---|
| Materiality concept | Double materiality | Financial (enterprise value) | Impact (stakeholder) | Financial (investor) |
| Primary audience | Investors + stakeholders | Investors / capital providers | Broad stakeholder set | Investors |
| Value chain scope | Own ops + up + downstream | Own ops + value chain | Own ops + value chain | Own operations |
| Assurance required | Limited (→ reasonable) | Jurisdictional | Voluntary | Voluntary |
| Legal basis | Directive + Delegated Reg. | IFRS Foundation standard | Voluntary global standard | Standard (merged into IFRS) |
| Interoperability with ESRS | — | Interoperability Guidance (May 2024) | High (impact materiality) | High (financial materiality) |

Frequently asked questions.
Eight questions grounded in EFRAG and Commission primary sources. Expand any question for the reference.
What is double materiality?
Double materiality is the principle under which an undertaking assesses sustainability matters from two perspectives simultaneously: impact materiality (the undertaking’s actual and potential impacts on people and the environment) and financial materiality (the effects of sustainability matters on the undertaking’s development, performance and position). A matter is material if it meets the threshold for either perspective, or both. Source · ESRS 1, EFRAG IG 1
Is double materiality still required after the Omnibus I Directive?
Yes. Directive (EU) 2026/47 retains double materiality as the foundational principle of CSRD reporting. What has changed is the scope of companies in-scope (threshold raised to 1,000 employees and €450 million net turnover), the volume of mandatory datapoints (reduced by approximately 61%), and the flexibility of the DMA process. Source · Directive (EU) 2026/47; EFRAG Simplified ESRS technical advice, 3 December 2025
Which ESRS version should I apply for FY 2026?
Wave 1 undertakings continue under the original ESRS (Commission Delegated Regulation (EU) 2023/2772) for reporting years up to and including 2026. The Simplified ESRS are expected to apply from FY 2027, with voluntary early application permitted for FY 2026 once the delegated act is adopted (expected mid-2026). Source · European Commission; EFRAG
What is the difference between top-down and bottom-up DMA?
The Simplified ESRS 1 permits undertakings to conduct the DMA either by starting from sustainability topics and assessing whether each is material (top-down), or by identifying individual impacts, risks and opportunities and aggregating upward (bottom-up). Qualitative analysis is sufficient where the conclusion is clear. Source · Draft Simplified ESRS 1, EFRAG, December 2025
How often must a DMA be updated?
Under the Simplified ESRS, a full DMA does not need to be repeated annually unless significant changes have occurred in the undertaking’s business model, value chain, or regulatory environment. Source · EFRAG Simplified ESRS technical advice, 3 December 2025
What is the difference between impact and financial materiality?
Impact materiality relates to the undertaking’s actual or potential impacts on people and the environment (inside-out perspective). It is assessed by reference to severity (scale, scope, irremediability) and, for potential impacts, likelihood. Financial materiality relates to sustainability matters that trigger financial effects on the undertaking (outside-in perspective), assessed by reference to magnitude, likelihood and time horizon. Source · ESRS 1; EFRAG IG 1
Do SMEs need to conduct a double materiality assessment?
Small and medium-sized undertakings are not in mandatory scope of CSRD following Directive (EU) 2026/47. However, SMEs that receive sustainability data requests from in-scope counterparties may align to the Voluntary SME Standard (VSME), which includes a simplified materiality assessment. The Detailed Omnibus Directive caps trickle-down requests at the VSME scope for undertakings below 1,000 employees. Source · Directive (EU) 2026/47; EFRAG VSME
How does the DMA connect to ESRS 2 IRO-1 and IRO-2 disclosures?
The outcomes of the DMA process are disclosed under ESRS 2 IRO-1 (description of the processes to identify and assess material impacts, risks and opportunities) and ESRS 2 IRO-2 (disclosure requirements in ESRS covered by the undertaking’s sustainability statement). These disclosures are required regardless of the materiality outcome of specific topics. Source · ESRS 2
