CSRD 2026 Double Materiality Analysis: SME Method

Quick answer. Double materiality analysis is the core exercise required by the CSRD directive (EU 2022/2464): identify material sustainability matters from an impact perspective (inside-out) and a financial perspective (outside-in), then disclose the corresponding ESRS indicators. As of 17 May 2026, the Omnibus package presented in February 2025 proposes a two-year postponement for waves 2 and 3 and raises CSRD thresholds to 1,000 employees.

Directive (EU) 2022/2464, known as CSRD, was transposed into French law through Ordinance No. 2023-1142 of 6 December 2023 and Decree No. 2023-1394 of 30 December 2023, codified in Articles L. 232-6-3 and R. 232-8-1 et seq. of the French Commercial Code. The sustainability report is now embedded in the management report and must follow the European ESRS standards published by EFRAG (the European Financial Reporting Advisory Group).

The initial implementation calendar covered four waves: large public interest entities (> 500 employees) for fiscal year 2024, other large companies for 2025, listed SMEs for 2026, and non-EU companies for 2028. The Omnibus package presented by the European Commission on 26 February 2025 proposes a two-year delay for waves 2 and 3, raised CSRD thresholds to 1,000 employees and €50 million net turnover, and a reduction in the number of ESRS datapoints required. Final texts are expected in spring 2026.

At Hayot Expertise, we have observed for the past 18 months that most of our mid-cap clients have engaged with the framework for operational reasons, regardless of their regulatory status: their large CSRD-bound customers are now sending them ESRS data requests through structured supplier questionnaires. This is the trickle-down effect, and it makes double materiality useful even for an SME under Omnibus exclusion.

The cross-cutting standard ESRS 1 defines double materiality as the simultaneous assessment of a topic from two perspectives. A sustainability matter is material if it exceeds the significance threshold on at least one of the two axes.

Impact Materiality (Inside-out)#

It measures the company's effects on people and the environment, whether actual or potential, positive or negative, over the short, medium, or long term. The scope covers the upstream and downstream value chain. Three assessment criteria: scale, scope, and irremediability. For potential impacts, a fourth criterion is added: likelihood of occurrence.

Concrete examples: Scope 1 and 2 greenhouse gas emissions documented in your carbon assessment, working conditions of Asian subcontractors, water pollution generated by a textile dyeing workshop, or the positive contribution of an internal training programme to local employment.

Financial Materiality (Outside-in)#

It measures how sustainability matters affect the company's financial performance, financial position, cash flows, access to capital, or cost of capital, over the short, medium, or long term. Two criteria: magnitude of financial effects and likelihood of occurrence.

Concrete examples: the extension of the European carbon market (ETS 2) raising road transport costs from 2027, a cobalt shortage halting battery production, the physical flood risk for a logistics warehouse along the Seine, or a commercial opportunity tied to an eco-designed product valued by customers themselves subject to the CSRD.

The European standards published by EFRAG comprise two cross-cutting standards (ESRS 1 and ESRS 2) and ten topical standards structured along E, S, and G pillars. Double materiality analysis sets the reporting scope: only material topics trigger detailed disclosure.

The assessment method follows the sequence required by ESRS 1 §41 et seq. At Hayot Expertise, we deliver it in four half-day workshops involving management, operational staff, and a focused panel of stakeholders.

1. Map the IROs. Exhaustively list impacts, risks, and opportunities by ESRS topic, by value chain segment, and by time horizon (short < 1 year, medium 1-5 years, long > 5 years). Internal sources: management interviews, existing risk map, product life cycle assessments. External sources: SASB/EFRAG sector materials, specialised press, stakeholder grievances.
2. Consult stakeholders. ESRS 1 §24 requires substantive engagement with affected stakeholders: employees, customers, suppliers, neighbouring communities, NGOs, investors. Minimum format: structured questionnaire plus three or four qualitative interviews per category. Consultation records must be archived for the auditor.
3. Score the IROs. For impact materiality: rate scale (1-5), scope (1-5), irremediability (1-5), and likelihood (1-5) for potential impacts. For financial materiality: financial magnitude (as a percentage of operating income) and likelihood. Define a documented significance threshold validated by the management committee.
4. Validate and arbitrate. Present the consolidated matrix to the management committee, ideally to the board. Document every arbitration decision: why a borderline IRO is excluded, why another just above the line is retained. Traceability is required by the independent third-party body (ITPB) during limited assurance audits.

The accredited independent third-party body must provide limited assurance on the sustainability report (Article L. 821-54 of the French Commercial Code). The following documents form the minimum archive:

• Methodology note describing the significance criteria (financial and impact) and their threshold
• Comprehensive IRO map with documented scoring
• Stakeholder consultation records (at least three distinct categories)
• Final double materiality matrix presented to the management committee (dated and signed)
• Mapping table linking material IROs to disclosed ESRS datapoints
• Policies, actions, and key performance indicators (KPIs) for each material topic
• Climate transition plan aligned with the Paris Agreement (ESRS E1-1) if E1 is material

• SMEs under Omnibus exclusion. EFRAG has published, since late 2024, the VSME standard (Voluntary SME), a simplified voluntary reporting framework. We recommend it to SMEs of 50-250 employees solicited by their customers: it avoids fragmented over-solicitation through heterogeneous questionnaires.
• French subsidiaries of consolidated groups. Article L. 232-6-3 of the French Commercial Code provides an exemption if the parent issues a compliant consolidated report. The subsidiary must nevertheless disclose this exemption and the location of the parent's published report.
• Mid-caps supplying large groups. Your CAC 40 customers send you CDP, EcoVadis, or custom ESRS matrices. Building your own double materiality analysis allows you to answer all solicitations once, instead of fielding inconsistent follow-ups.
• International groups. The articulation between CSRD, US SEC climate rules, TCFD, and IFRS S1-S2 is complex; our international accounting team builds a unified framework that serves all regimes.

• Conflating impact materiality and financial materiality. The two dimensions have different criteria, horizons, and stakeholders. The test must be conducted separately then consolidated, not mixed into a single grid.
• Underinvesting in stakeholder consultation. A simple internal survey does not suffice. ESRS 1 §24 requires substantive engagement: qualitative interviews, workshops, archived written records.
• Importing a "standard" matrix from a consulting firm. Every company has its own IRO map. Generic sector matrices are a useful starting point, never an acceptable deliverable for the ITPB.
• Overlooking the long-term horizon. The CSRD requires assessing impacts beyond five years. Physical climate risks (heatwaves, floods, droughts) typically materialise over that horizon and are systematically underestimated in early analyses.
• Disconnecting from financial accounting. Material topics must be reconciled with the balance sheet and income statement. A dismantling provision or an impaired climate-exposed asset must be consistent with the ESRS matrix.

Recently, an industrial mid-cap of 480 employees (€92 million turnover), a tier-1 supplier to a German car manufacturer, contacted us after receiving a 240-line ESRS questionnaire from its customer. The management was considering delegating the matter to a Parisian consulting firm whose quote exceeded €80,000 for the first year.

We proposed an alternative approach in four half-day workshops over ten weeks, co-facilitated by our ESG team and the in-house QHSE director. Total cost: under €25,000. Deliverable: a double materiality matrix validated by the management committee, a methodology dossier defensible before the ITPB, and an automated answer grid for the customer questionnaire. Six months later, the same customer renewed and expanded its orders.

The lesson from these engagements: double materiality is not an endless inventory exercise; it is a strategic steering tool. When conducted by the internal team with rigorous methodological support, it surfaces operational blind spots (often a critical supplier with weak contracts or an under-insured physical risk) far more useful than ticking a disclosure box.

Hayot Expertise Advice. Never fully outsource your double materiality analysis to an external consultant. Knowledge of your matters must remain inside the company. Mobilise your management committee, your QHSE lead, and a small but representative panel of stakeholders. The chartered accountant structures the method and secures auditability; your teams bring the substance. This division of roles is what makes the exercise sustainable and acceptable to the ITPB.

• Double materiality analysis is the cornerstone of the CSRD: it combines impact (inside-out) and financial (outside-in) perspectives to identify material matters.
• Four-step methodology: map the IROs, consult stakeholders, score, validate at management committee level.
• The 2025 Omnibus package postpones waves 2 and 3 by two years and raises thresholds to 1,000 employees.
• Even without direct obligation, SMEs experience the trickle-down effect through supplier questionnaires from their CSRD-bound customers.
• The EFRAG VSME standard offers SMEs of 50-250 employees a simplified framework to handle such requests.
• Auditability is required: keep evidence of stakeholder consultation, scoring, arbitration decisions, and the matrix validated by management.
