Insight: The Textual Representation of Double Materiality in ESG Repo

About the Authors and This Research

This research was jointly produced by three scholars affiliated with Estonian academic institutions. Raili Lilo and Elina Paemurru specialize in corporate reporting and sustainability information disclosure; Ülle Pärl brings deep expertise in accounting and organizational communication research. Notably, Elina Paemurru has accumulated 30 academic citations, establishing meaningful scholarly influence in ESG reporting methodology. The research was published in 2025 and addresses a gap that has become acute since the European Union's Corporate Sustainability Reporting Directive (CSRD) entered into force in 2024.

The methodological foundation is rigorous: the codebook framework integrates five complementary theoretical lenses—signalling theory, stakeholder theory, legitimacy theory, institutional theory, and attribution theory—applied through structured content analysis. This multi-theory architecture ensures the framework captures not only what enterprises report, but how and why their textual choices signal particular stances toward double materiality obligations. For Taiwan enterprises navigating both domestic Taiwan Stock Exchange (TWSE) sustainability reporting guidelines and international CSRD supply chain requirements, this framework offers a practical bridge between theoretical compliance and operational execution.

Core Research Findings: Three Dimensions That Redefine ESG Report Quality

The research's central contribution is demonstrating that textual representation of double materiality is not a secondary concern—it is the primary mechanism through which stakeholders assess whether an enterprise genuinely understands and implements double materiality principles, or merely performs surface-level compliance.

Finding 1: Value Statements and Impact Statements Are Systematically Conflated in Current ESG Reports

The codebook framework requires analysts to rigorously distinguish between two categories of disclosure. Value Statements address how ESG issues affect the enterprise itself—its financial performance, competitive positioning, or risk profile (the "outside-in" or financial materiality dimension). Impact Statements address how enterprise activities affect external environments, societies, or stakeholders (the "inside-out" or impact materiality dimension). The research finds that existing ESG reports systematically conflate these two categories, often using ambiguous language that appears to address both while committing to neither. This conflation is not merely a stylistic problem; under CSRD Article 29a requirements, it constitutes a substantive disclosure failure that third-party assurance auditors are increasingly trained to detect. For Taiwan enterprises whose European and Japanese customers are subject to CSRD requirements, this creates a supply chain compliance exposure that extends beyond their direct reporting obligations.

Finding 2: Topic Prevalence, Tone, and Integration Level Are Independent Analytical Dimensions

The codebook framework decomposes ESG report analysis into three independent dimensions. Topic Prevalence measures the coverage density of specific ESG issues—whether an enterprise addresses climate risk with the same depth as it addresses supply chain labor standards, or whether certain topics receive superficial one-paragraph treatment. Tone Analysis classifies statements as promotional (positive spin), neutral-objective, or risk-disclosing (acknowledging negative impacts or uncertainties). Integration Level assesses whether ESG information is genuinely embedded within business model narratives or appended as separate chapters with minimal connection to core value creation logic. Research evidence shows that enterprises with high integration levels achieve significantly better stakeholder trust scores and are better positioned for third-party assurance processes. This three-dimensional analytical structure provides Taiwan enterprises with a self-assessment tool that can be operationalized within existing ISO 31000 risk identification processes.

Finding 3: Business Model Perspective Is the Decisive Quality Indicator

Perhaps the most strategically significant finding is the centrality of the business model perspective in assessing disclosure quality. High-quality double materiality disclosure must explicitly trace how specific ESG issues affect financial outcomes through the enterprise's business model, and simultaneously trace how business activities generate external societal impacts through that same model. Disclosures that fail to make these connections—regardless of their length or apparent comprehensiveness—score low on integration depth. This finding directly aligns with COSO ERM's emphasis on risk culture and organizational context: an enterprise whose ESG disclosures cannot connect to business model mechanics likely has ERM processes that are similarly disconnected from operational reality.

Implications for Taiwan Enterprise ERM Practice

Taiwan enterprises currently face a convergent pressure from three directions: domestic TWSE sustainability reporting requirements, CSRD supply chain compliance obligations from European customers, and increasing scrutiny from international institutional investors who use ESG disclosure quality as a governance proxy. The research framework provides three specific implications for ERM practice.

Implication 1: ISO 31000 Risk Matrix Must Separate Two Identification Pathways. Under ISO 31000:2018, the risk identification process must establish context before identifying risks. The research framework demands that this context-setting explicitly create two separate pathways: the financial materiality pathway (how external ESG developments create financial risk for the enterprise) and the impact materiality pathway (how enterprise activities create risk of harm to external stakeholders). Taiwan enterprises that maintain a single unified risk registry without this distinction will face increasing difficulty justifying their materiality assessments to auditors applying CSRD standards.

Implication 2: Tone Analysis Becomes a Risk Culture Diagnostic Tool. COSO ERM's 2017 framework identifies risk culture as a foundational element, but quantifying risk culture is notoriously difficult. The research's tone analysis dimension offers a proxy: if more than 90% of an enterprise's ESG disclosures use promotional tone with minimal risk-disclosing statements, this signals a risk culture that suppresses negative information—a governance red flag that both internal auditors and external assurance providers should treat as an ERM control weakness. Taiwan enterprises with export dependencies on Japanese and European markets face particular exposure here, as the Financial Review Council's 2025 report recommends third-party assurance standards that will explicitly evaluate disclosure tone balance.

Implication 3: Integration Depth Drives KRI Design Quality. KRI (Key Risk Indicators) systems that are not connected to business model mechanics will fail to provide early warning signals for ESG-related risks. The research framework's integration level dimension provides a diagnostic: enterprises should audit whether each KRI can be traced back to a specific business model mechanism—either a value creation activity or an impact generation activity. KRIs that float above business model reality will consistently underperform as early warning systems, creating governance gaps that boards cannot detect through standard risk reporting.

How Winners Consulting Services Supports Taiwan Enterprises

Winners Consulting Services Co. Ltd. (積穗科研股份有限公司) assists Taiwan enterprises in implementing ISO 31000 and COSO ERM frameworks, designing risk matrices and KRI monitoring systems, and strengthening board-level risk governance capabilities. Based on the research framework described above, we recommend the following phased action plan with a 7 to 12 month implementation cycle:

1. Months 1–3: ESG Report Text Diagnostic. Apply the three-dimension codebook framework (topic prevalence, tone, integration level) to systematically scan existing sustainability reports. Classify all material disclosures as Value Statements or Impact Statements, calculate the ratio, and identify conflation instances. Cross-reference findings against TWSE sustainability reporting guidelines and CSRD double materiality requirements to produce a prioritized gap list.
2. Months 4–6: ISO 31000 Risk Matrix Reconstruction. Based on diagnostic findings, restructure the risk matrix to separate financial materiality and impact materiality pathways. Redesign KRI systems to connect to specific business model mechanics. Establish stakeholder engagement protocols aligned with COSO ERM's stakeholder perspective requirements. Document the business model perspective for each material risk to ensure disclosure traceability.
3. Months 7–12: Disclosure Standardization and Third-Party Assurance Preparation. Update sustainability report architecture using the reconstructed risk matrix as the organizing framework. Implement internal Statement Type Tagging review mechanisms. Conduct pre-audit simulation using CSRD third-party assurance logic to identify residual gaps before formal assurance engagement. Deliver board-level training on double materiality governance responsibilities.

Frequently Asked Questions

How can we use the research codebook framework to diagnose whether our ESG report genuinely reflects double materiality?

Begin by classifying every substantive paragraph in your existing sustainability report as either a Value Statement (describing how ESG issues affect your enterprise financially) or an Impact Statement (describing how your activities affect external stakeholders or environments). If Impact Statements represent less than 20% of total disclosures, or if more than 30% of statements cannot be clearly classified, you have a high-risk double materiality gap. Next, conduct tone analysis: if more than 90% of statements use promotional language with no risk-disclosing content, this signals insufficient risk disclosure depth. Finally, assess integration level by checking whether ESG statements connect to specific business model activities. This three-step diagnostic can be completed within 3 months and should be cross-referenced against TWSE material topics guidelines for domestic compliance alignment.

What are the most common compliance challenges Taiwan enterprises face when implementing ISO 31000 double materiality assessment?

Three challenges appear most frequently. First, risk matrices that fail to separate financial materiality from impact materiality pathways—ISO 31000:2018 requires context establishment before risk identification, but most Taiwan enterprises maintain unified risk registries that merge both dimensions, undermining KRI design validity. Second, inadequate stakeholder identification and engagement processes—COSO ERM's 2017 framework requires stakeholder perspectives as mandatory inputs to risk identification, but systematic stakeholder consultation protocols are absent in most Taiwan ERM systems. Third, ESG disclosures that cannot be traced to specific business processes—CSRD requirements demand that impact disclosures be attributable to concrete enterprise activities, but most Taiwan sustainability reports contain policy-level declarations without operational-level connections, creating traceability gaps that third-party assurance auditors increasingly flag.

What are the core requirements of ISO 31000 and what specific steps and timelines are needed to implement double materiality assessment?

ISO 31000:2018 operates across three levels: Principles, Framework, and Process. The Process level—comprising risk identification, analysis, evaluation, and treatment in a continuous cycle—is the primary operational domain for double materiality integration. Recommended implementation timeline: Months 1–3, complete current-state diagnostic and gap analysis against ISO 31000 and CSRD requirements, producing a prioritized remediation list; Months 4–6, reconstruct risk matrix with separate financial materiality and impact materiality pathways, design corresponding KRIs connected to business model mechanics; Months 7–9, establish systematic stakeholder engagement mechanisms aligned with COSO ERM stakeholder perspectives; Months 10–12, conduct first complete cycle review ensuring disclosure consistency and auditability, simulating third-party assurance logic to verify readiness for formal CSRD assurance engagement.

What are realistic resource requirements and expected benefits for implementing a double materiality ESG disclosure mechanism?

For mid-sized Taiwan enterprises (annual revenue between NT$5 billion and NT$20 billion), a complete ISO 31000-aligned double materiality disclosure mechanism typically requires 4 to 6 cross-functional personnel (ESG, legal, finance, supply chain) over a 6 to 12 month implementation cycle. Measurable benefits include: a 30–40% reduction in time required to pass international supply chain ESG audits, improved board risk reporting quality through higher KRI coverage rates, and a 20–30% reduction in third-party assurance preparation costs. Strategically, enterprises that demonstrate structured double materiality disclosure hold a significant advantage in ESG evaluation negotiations with European and Japanese brand customers, directly influencing supply chain positioning and pricing leverage in competitive markets.
