Double Materiality Assessments and Why Regulators Are Increasingly Rejecting Them

In April 2025, Frankfurt prosecutors fined Deutsche Bank's asset management arm DWS €25 million for misleading the capital markets about its sustainability credentials. The core finding was stark: DWS had called itself an "ESG leader" and claimed that ESG was "an integral part of our DNA," but its internal processes did not support those statements. This came on top of a $19 million SEC penalty in 2023 for the same conduct. The trigger was not a data breach or a failed audit. It was a gap between what the firm said publicly about its materiality determinations and what it could actually demonstrate operationally. That gap is exactly the risk that double materiality assessments are supposed to close. For most multinationals preparing to report under the EU's Corporate Sustainability Reporting Directive, the assessment process remains poorly understood, poorly governed, and poorly connected to the systems that generate defensible data.

The regulatory ground has shifted dramatically in the past twelve months. The Omnibus I directive, formally adopted by the EU Council in February 2026, narrows CSRD scope to companies exceeding both 1,000 employees and €450 million in net turnover, removing roughly 90% of previously covered entities. EFRAG's simplified ESRS, delivered to the European Commission in December 2025, cuts mandatory data points by 61% and eliminates all voluntary disclosures, producing an overall 70% reduction from around 1,073 to approximately 320 data points. For the companies that remain in scope, however, these changes do not reduce the burden of getting double materiality right.

The Simplification Paradox: Fewer Data Points, Higher Stakes Per Decision

The political logic behind the Omnibus is straightforward: reduce reporting burden, protect competitiveness, focus resources on the largest entities with the most material impacts. But the operational consequence is counterintuitive. Under the original ESRS framework, companies could rely on the sheer volume of prescribed disclosures as a form of insurance. Reporting on 1,073 data points left less room for the accusation that something material had been overlooked. Under the simplified standards, with only around 320 data points required if material, each determination the company makes about what is and is not material carries substantially more weight.

The revised ESRS introduce a "top-down" approach to materiality, allowing companies to begin at the strategic level by examining their business model, sector, and key activities before drilling into specific topics. EFRAG has also expanded the "undue cost or effort" exemption, permitting companies to omit information where preparing a disclosure would be disproportionate relative to its usefulness. Both of these changes are reasonable in principle. In practice, they shift a significant amount of judgment to the reporting entity, and judgment, unlike a checkbox, requires governance.

This is the crux of the issue. A principles-based materiality assessment demands stronger internal controls, not weaker ones, because every determination must be supported by documented reasoning, stakeholder engagement records, and a clear link between identified impacts, risks, and opportunities and the company's operational reality. Finance Watch has flagged that the expanded "undue cost or effort" relief risks creating heterogeneous practices across the market and reducing comparability of ESG data. For companies, this means that the burden of proof does not vanish when a data point is cut. It migrates from the disclosure itself to the documentation supporting the decision not to disclose. Audit committees and assurance providers will scrutinize these omissions. A company that cannot explain, with specificity, why it excluded a topic from its double materiality assessment will face the same credibility deficit that sank DWS.

The Materiality Divergence Problem Across Jurisdictions

For multinationals operating across the EU, the UK, Australia, and North America, double materiality under CSRD represents just one layer of a fragmented disclosure landscape. The ISSB standards (IFRS S1 and S2), which focus exclusively on financial materiality, are being adopted or referenced by jurisdictions including the UK, Canada, Singapore, and Australia. The EU's ESRS requires both financial materiality and impact materiality. These are not the same thing, and reconciling them inside a single reporting architecture is a genuine operational challenge.

Research published by the European Corporate Governance Institute demonstrates that a single materiality approach incentivizes firms to improve performance on financially material sustainability issues while performance on financially immaterial issues declines. The practical implication is that a company reporting exclusively under ISSB standards may rationally deprioritize topics that a double materiality assessment under ESRS would require it to evaluate. When the same company must also satisfy EU requirements, those topics re-enter scope. The internal data architecture must accommodate both lenses simultaneously.

In September 2025, the ISSB publicly asked the EU to adopt its standards as a baseline and "top up" with double materiality requirements, according to reporting by Responsible Investor. EFRAG's revised standards have moved toward enhanced interoperability with ISSB, including harmonized terminology and revised GHG boundary provisions. But interoperability on paper does not resolve the fundamental structural question: who inside the company owns the process of reconciling a topic that is impact-material under ESRS but not financially material under ISSB, and how does that reconciliation get documented and assured?

For general counsel and compliance leaders, this creates a concrete risk. If a company discloses a topic as material under CSRD but does not address it in its ISSB-aligned reporting to UK or Australian regulators, the inconsistency becomes a liability vector. Conversely, if it omits a topic from ESRS reporting that it treats as material in another jurisdiction, the omission invites regulatory scrutiny in the EU. The solution is not to pick one standard and hope for the best. It is to build a single materiality assessment process that captures both financial and impact dimensions, documents the reasoning for each jurisdiction's treatment, and routes the outputs to the correct disclosure framework. Most companies do not have this architecture in place.

If you are unsure whether your organization's current approach to materiality can hold up across multiple regulatory regimes, our Regulatory Readiness Assessment provides a free, structured diagnostic across CSRD, ISSB, and other frameworks to identify your specific gaps before they become audit findings.

Greenwashing Enforcement and the Materiality Evidence Gap

The connection between weak materiality assessments and greenwashing exposure is direct, though not always obvious. Most enforcement actions to date have not targeted the materiality assessment itself. They have targeted the downstream consequences of assessments that were too shallow: claims that could not be substantiated, screens that were not implemented, targets that contradicted actual emissions trajectories. But as assurance requirements tighten under CSRD and regulators develop more granular review capabilities, the assessment process itself will come under scrutiny.

Consider the pattern emerging across jurisdictions. In Australia, the Federal Court fined Active Super A$10.5 million in March 2025 for claiming to exclude certain industries from its investment screens while continuing to hold securities in those sectors. In Italy, AGCM fined Shein €1 million in August 2025 for marketing sustainability claims contradicted by its own rising emissions data. In each case, the root cause was identical: the organization made public assertions about its sustainability posture that its internal processes could not support. A robust double materiality assessment, connected to operational data and reviewed against actual business activities, would have flagged these inconsistencies before they became public representations.

The UK's Digital Markets, Competition and Consumers Act, which took effect in April 2025, gives the Competition and Markets Authority power to levy fines of up to 10% of global turnover for misleading environmental claims without requiring court proceedings. Canada's amended Competition Act now imposes fines of up to 3% of annual worldwide revenue for unsubstantiated environmental claims. The CSDDD, though narrowed by Omnibus, still carries a penalty cap of 3% of net worldwide turnover. The enforcement trend across jurisdictions is clear and consistent: regulators are moving from advisory guidance toward direct financial penalties, and the evidentiary basis for those penalties will increasingly include the quality and completeness of the company's materiality determination process.

This has a specific operational implication for marketing and communications teams. Any public sustainability claim, whether in an annual report, a product page, or a press release, must be traceable to a materiality determination supported by evidence. The legal review process for sustainability communications must include a step that maps each claim back to the double materiality assessment outputs. Companies that treat their materiality assessment as a standalone compliance exercise, disconnected from the teams that generate external communications, are building an enforcement liability in real time.

Building a Decision-Grade Materiality Process: An Operational Framework

The distinction between a compliant materiality assessment and a decision-grade one matters more under the simplified ESRS than it did under the original framework. A compliant assessment meets the procedural requirements: stakeholder engagement was conducted, impacts were scored, financial risks were mapped. A decision-grade assessment goes further. It produces outputs that can withstand assurance review, inform capital allocation decisions, and anchor the company's sustainability communications with specificity. Decision-grade means every material topic determination is supported by documented evidence, traceable methodology, and clear ownership at the board or senior leadership level.

The first operational decision point is ownership. Double materiality cannot be delegated exclusively to the sustainability function. The financial materiality dimension requires input from risk management, treasury, and finance. The impact materiality dimension requires input from operations, procurement, and legal. The reconciliation of topics across jurisdictions requires someone with the authority to make trade-off decisions when the two dimensions point in different directions. In practice, this means the materiality assessment must be governed by a cross-functional steering committee with a clear mandate from the board, not run as a side project by a single team.

The second decision point is the threshold methodology. Under the simplified ESRS, companies must define their own materiality thresholds. This is where most assessments fail. Thresholds that are too low produce assessments bloated with immaterial topics, wasting assurance and reporting resources. Thresholds that are too high expose the company to the accusation that it deliberately excluded inconvenient topics. The methodology must define, in writing, the criteria for severity (scale, scope, irremediable character for impacts; likelihood and magnitude for financial risks), the time horizons applied, and the rationale for any qualitative overrides. This documentation is not a formality. It is the artifact that assurance providers will test. If the threshold methodology cannot be explained to an auditor in concrete terms, it is not defensible.

The third decision point is the connection between the assessment and the data architecture. A materiality determination that concludes "climate change is material" but cannot specify which Scope 1, 2, or 3 categories require measurement, at what level of precision, using which data sources, is operationally useless. Each material topic must be mapped to specific disclosure requirements under the applicable ESRS standard, and each disclosure requirement must be mapped to a data owner, a data source, and a quality control process. This mapping exercise is where most organizations discover that their systems are not built for the reporting they have committed to. Discovering this gap during the assessment, rather than during the reporting cycle, is the difference between a manageable remediation project and a last-minute scramble that produces unreliable disclosures.

The fourth decision point is how the assessment connects to ongoing governance. A double materiality assessment is not a one-time compliance event. Topics shift in materiality as the business evolves, as regulations change, and as stakeholder expectations develop. The simplified ESRS explicitly encourage a proportionate, principles-based approach that assumes materiality will be revisited. Companies need a defined trigger for reassessment: a material acquisition, a regulatory change, a significant operational incident, or a predetermined annual review cycle. Without this, the assessment becomes stale and the company's disclosures drift away from reality, which is precisely the pattern that enforcement actions have targeted.

The fifth and most consequential decision point is the treatment of topics that are impact-material but not financially material. This is where double materiality earns its name and where most organizations struggle. The temptation is to assess these topics lightly and disclose them minimally. But impact-material topics have a tendency to migrate toward financial materiality over time, a concept the World Economic Forum has described as "dynamic materiality." A company that identifies deforestation risk in its supply chain as impact-material today but not yet financially material, and therefore invests minimally in data collection, may find itself two years later facing import restrictions under the EU Deforestation Regulation, lender scrutiny under the EU Taxonomy, and reputational exposure from an NGO campaign. The assessment process must include a forward-looking analysis of dynamic materiality for each impact-material topic, connected to the company's risk register and strategic planning processes.

What Comes Next: The Transition Window Is Narrower Than It Appears

Companies remaining in CSRD scope under the Omnibus thresholds will report on FY2027 data, with reports due in 2028. That timeline appears generous. It is not. The simplified ESRS will be adopted by the European Commission via delegated act, expected by mid-2026. Companies need to complete or refresh their double materiality assessments and build the supporting data infrastructure by the end of 2026 to produce auditable disclosures for FY2027. For Wave 1 reporters already publishing under the original ESRS, the transition to simplified standards introduces its own complexity: determining which data points are no longer required, which flexibility mechanisms to apply, and how to maintain comparability across reporting periods.

Non-EU companies subject to Article 40a reporting face additional uncertainty. Under the Omnibus, a third-country group falls into CSRD scope if a single EU subsidiary exceeds €200 million in net turnover and the parent's EU-wide turnover exceeds €450 million for each of the last two consecutive financial years. There is no employee threshold for this trigger. US and UK multinationals with significant European operations need to scope their exposure under these revised thresholds now.

The firms that will navigate this well are the ones that treat double materiality not as a reporting requirement to be minimized but as a governance tool that connects sustainability risk to operational decision-making. The simplified ESRS, paradoxically, makes this harder by removing the procedural scaffolding that structured earlier assessments. What remains is a framework that demands judgment, evidence, and cross-functional coordination. Companies that can deliver those three things will produce credible disclosures. Companies that cannot will produce documents that collapse under regulatory scrutiny, audit testing, or the next enforcement cycle.

Why Now

The complexity mapped out in this analysis, the multi-jurisdictional divergence, the governance gaps, the connection between materiality determinations and downstream enforcement exposure, does not resolve itself through better awareness alone. It requires structured intervention: a systematic review of the company's materiality process, data architecture, and governance model against the requirements it will actually face.

At Gasilov Group, our Cross-Jurisdictional Materiality Diagnostic begins with a 90-day scoping engagement that maps your entity structure against CSRD, ISSB, and applicable national frameworks to identify where your materiality determinations are misaligned, undocumented, or unsupported by auditable data. The first deliverable is a prioritized gap register with specific remediation actions organized by regulatory deadline. Contact us to schedule a scoping call.

Frequently Asked Questions (FAQ):

Does the simplified ESRS eliminate the requirement to conduct a double materiality assessment under CSRD?

No. The Omnibus I directive and EFRAG's simplified standards preserve double materiality as a foundational requirement for all in-scope companies. What has changed is the process mechanics: EFRAG now permits a 'top-down' approach that begins with the company's business model and sector context rather than requiring an exhaustive bottom-up analysis of every ESRS topic. Companies can also apply the 'undue cost or effort' exemption to certain disclosures, but this exemption does not apply to the materiality assessment itself. The assessment must still evaluate both impact materiality and financial materiality, and documentation of the methodology and conclusions remains subject to limited assurance.

Can a double materiality assessment conducted under CSRD also satisfy ISSB reporting requirements in other jurisdictions?

In principle, yes, because a well-executed double materiality assessment captures financial materiality as a subset. However, the specific format, thresholds, and disclosure requirements differ. ISSB standards use 'enterprise value' as the anchor for financial materiality, while ESRS references 'financial effects' more broadly, including effects on cash flows, access to finance, and cost of capital. Companies reporting under both frameworks should design a single integrated assessment process and then map the outputs to each framework's specific requirements, rather than running two separate processes that produce inconsistent results.

How does double materiality relate to greenwashing enforcement risk for non-EU companies?

The connection is indirect but consequential. Non-EU companies that fall within CSRD scope under the Article 40a provisions must conduct a double materiality assessment as part of their reporting obligations. But even for companies outside CSRD scope, the materiality assessment methodology provides a defensible basis for sustainability claims made in any jurisdiction. Regulators in Australia, the UK, and Canada have all imposed significant penalties on companies whose public sustainability claims could not be substantiated by internal processes. A documented materiality assessment that links each public claim to evidence and methodology significantly reduces this exposure, regardless of whether the company is legally required to conduct one.

What is the practical difference between the 'top-down' materiality approach in the simplified ESRS and the original EFRAG methodology?

The original ESRS required companies to systematically evaluate every sustainability topic listed in the standards against both materiality dimensions, which in practice meant scoring dozens of subtopics across environmental, social, and governance categories. The simplified approach allows companies to start from their sector profile and business model, identify the most obviously relevant topics first, and then evaluate remaining topics at a higher level to confirm they are not material. This reduces the volume of detailed analysis required but places greater emphasis on the quality of the initial strategic assessment and the documentation supporting any decision to exclude a topic. Companies with diversified operations across multiple sectors may find the top-down approach more difficult to apply than companies with concentrated business models.

What internal controls should be in place before a company begins its first double materiality assessment under the simplified ESRS?

Before starting the assessment, companies should have four things in place: a formally mandated cross-functional steering committee with board-level sponsorship; a documented threshold methodology that defines how severity, likelihood, and time horizons will be scored for both impact and financial materiality; a stakeholder mapping exercise that identifies which groups will be engaged and through which channels; and a data inventory that catalogs existing sustainability data sources, their owners, and their quality limitations. Companies that begin the assessment without these foundations typically produce results that cannot survive the limited assurance process, requiring a costly restart. The simplified ESRS also requires companies to demonstrate connectivity between their sustainability disclosures and their financial statements, which means the finance function must be involved from the earliest design stage.
