Double Materiality Assessment
Netherlands

Double materiality assessment in Netherlands: Wet implementatie CSRD (CSRD Implementation Act)

The Netherlands transposed the CSRD through the Wet implementatie CSRD, amending the Burgerlijk Wetboek (Civil Code) Book 2 to incorporate sustainability reporting obligations. The Dutch transposition follows the EU directive's phasing timeline without significant deviations: Wave 1 entities (large public-interest entities already subject to NFRD) report for financial years from 1 January 2024, Wave 2 (other large undertakings) from 1 January 2025, and Wave 3 (listed SMEs) from 1 January 2026. The double materiality assessment under ESRS 1.20-33 applies directly through the ESRS delegated acts. The Netherlands has a strong tradition of sustainability reporting. Many Dutch listed companies have published integrated reports aligned with the GRI Standards or the International Integrated Reporting Framework for over a decade. The Royal NBA (Koninklijke Nederlandse Beroepsorganisatie van Accountants) has been active in developing sustainability assurance capability. This institutional readiness gives Dutch entities a head start on CSRD implementation, but existing voluntary practices do not automatically satisfy the ESRS requirements. The double materiality methodology in ESRS 1.20-33 is more structured and prescriptive than most voluntary approaches.

Regulatory context: Autoriteit Financiële Markten (AFM)

The AFM is the primary enforcement body for sustainability reporting by listed entities in the Netherlands. The AFM has been vocal about its expectations for CSRD compliance. In its 2024 annual report, the AFM stated that it will prioritise the quality of double materiality assessments in its first enforcement reviews, focusing on whether entities have followed a documented process, engaged stakeholders, and applied the ESRS severity and likelihood criteria rather than relying on informal judgement. The AFM's approach builds on its experience enforcing financial reporting under IFRS. The AFM uses a risk-based selection model to identify entities for detailed review and can require corrections to published reports. For sustainability reporting, the AFM has indicated it will initially focus on large listed entities in high-impact sectors (energy, financials, chemicals) where the double materiality assessment is most complex and the public interest is greatest. The NBA has published practice guidance on sustainability assurance, building on the Dutch Standard 3810N (which governed assurance on non-financial information before CSRD). The NBA's guidance emphasises that assurance providers must evaluate whether the entity's materiality assessment process meets ESRS requirements, not just whether the entity has produced a materiality matrix. The distinction matters: many Dutch entities have published materiality matrices for years, but few meet the documentation and scoring rigour of ESRS 1.20-33.

Practical guidance for Netherlands

Dutch entities should start the double materiality assessment by assembling a cross-functional team. The Netherlands' two-tier board structure (Raad van Bestuur and Raad van Commissarissen) means the supervisory board should be informed of the assessment methodology and conclusions, particularly where material topics create financial risk exposure. ESRS 2 GOV-1 requires disclosure of the governance body's role in sustainability matters, which includes oversight of the materiality assessment. For the impact materiality assessment, engage stakeholders early. Dutch corporate governance culture, shaped by the Rijnlands model, places emphasis on stakeholder inclusion. Use existing stakeholder relationships (employee councils per the Wet op de ondernemingsraden, community engagement from environmental permits, customer feedback channels) as inputs. For financial materiality, draw on the entity's existing enterprise risk management framework and supplement with sustainability-specific risk identification. Dutch entities with LkSG obligations in Germany (those with German operations or sales above the German threshold) can coordinate data collection across both frameworks. Similarly, entities already reporting under the EU Taxonomy should map their Taxonomy assessment data to the ESRS topics, as the underlying sustainability matters overlap significantly.

Audit expectations

Dutch registeraccountants providing limited assurance on sustainability reports must hold the appropriate qualification from the NBA. The NBA has established a sustainability assurance licensing regime that requires additional training beyond the standard RA qualification. Assurance providers must evaluate the double materiality assessment as part of their engagement procedures, with specific attention to whether the entity considered all ESRS topics, documented scoring criteria, engaged stakeholders, and applied thresholds consistently. The AFM inspects audit quality through its regular inspection programme and has indicated it will extend this to sustainability assurance engagements. The AFM's existing inspection findings on financial statement audits (published annually) provide a baseline: the AFM has consistently flagged insufficient professional scepticism and inadequate documentation as common audit quality issues. These themes will likely carry over into sustainability assurance inspections.

Netherlands-specific considerations

The Netherlands' specific context adds several dimensions to the double materiality assessment. The country's geographic position (low-lying, flood-prone) makes E1 Climate change physical risk particularly acute for entities with assets below sea level. The Deltaprogramma and Klimaatakkoord (Climate Agreement) set national targets that affect entity-level financial materiality through regulatory costs and transition requirements. Dutch entities in the agricultural sector face specific E2 and E3 materiality considerations due to the nitrogen crisis (stikstofcrisis). The Dutch government's mandatory reduction in nitrogen oxide and ammonia emissions has direct financial consequences for agricultural entities (forced capacity reduction, permit revocation) and creates impact materiality through pollution effects on Natura 2000 habitats. Agricultural entities should score E2 and E4 with specific reference to the stikstofcrisis regulatory context. The Netherlands' pension sector is among the largest in Europe. Pension funds and asset managers in scope of CSRD face the same financed-emissions challenges as banks, with additional complexity from the long-term investment horizons and beneficiary obligations that characterise pension fund operations. The Pensioenfederatie has published guidance on CSRD readiness for Dutch pension funds.

Common inspection findings

The AFM's 2024 thematic review of early CSRD adopters found that most entities had performed a materiality assessment but fewer than half had documented the scoring methodology in sufficient detail to support assurance.

The AFM flagged that entities frequently relied on external consultants to produce the materiality assessment without adequate internal oversight, creating a risk that the assessment does not reflect the entity's actual operations and risk profile.

The AFM observed that stakeholder engagement in materiality assessments was often limited to management interviews, without input from employee councils, customers, or community representatives as expected by ESRS 1.24.

NBA inspection findings from early sustainability assurance engagements indicated that assurance providers were accepting entity-prepared materiality matrices without independently evaluating the underlying scoring and methodology.

The AFM noted that Dutch financial institutions were not consistently assessing financed emissions under E1, despite the sector's high exposure to climate transition risk through lending and investment portfolios.
