material sustainability issues

Material sustainability issues are topics identified through a 'double materiality' assessment, a core requirement of the EU's Corporate Sustainability Reporting Directive (CSRD) and defined in ESRS 1. This approach has two dimensions: 'impact materiality,' which considers the company's actual or potential significant impacts on people and the environment (an inside-out view), and 'financial materiality,' which considers the risks and opportunities that sustainability matters pose to the company's financial performance and development (an outside-in view). This dual perspective is a key differentiator from older frameworks that focused solely on financial materiality. In an ERM context like ISO 31000, the results of this assessment are a critical input for risk identification, ensuring ESG factors are integrated into the overall corporate strategy and risk appetite.

Application in ERM is executed via a double materiality assessment. Step 1: Scoping and IRO Identification: Map the value chain and identify a comprehensive list of potential sustainability impacts, risks, and opportunities (IROs) based on ESRS standards. Step 2: Materiality Assessment: Evaluate each IRO against predefined criteria for both impact materiality (considering scale, scope, and irremediability) and financial materiality (considering likelihood and magnitude of financial effects), and set materiality thresholds. Step 3: Consolidation and Reporting: Aggregate the IROs that exceed either threshold into a final list of material sustainability issues. These issues are then integrated into the enterprise risk register for mitigation, monitoring, and strategic planning. For example, a Taiwanese tech firm might identify water scarcity as material due to both operational disruption risk (financial) and its impact on local communities (impact), leading to enhanced water management strategies.

Taiwanese enterprises face three key challenges. First, data availability and quality, especially for value chain impacts like Scope 3 emissions or supply chain human rights. The solution is to start with industry averages and proxy data while implementing a phased data collection strategy using digital platforms. Second, a mindset shift from single (financial-only) to double materiality. Overcoming this requires executive workshops that link impact materiality to long-term brand value and social license to operate. Third, a lack of cross-functional collaboration. This can be solved by establishing a C-level-led, cross-departmental ESG task force with a clear mandate and shared KPIs to break down information silos. A priority is to integrate the process into the existing ISO 31000 risk framework.
