ISSB IFRS Sustainability Disclosure Standards

The International Sustainability Standards Board (ISSB), under the IFRS Foundation, develops a global baseline for sustainability disclosures. Its core standards, IFRS S1 (General Requirements) and IFRS S2 (Climate-related Disclosures), mandate that companies report on significant sustainability-related risks and opportunities from an investor's perspective. The goal is to clarify how these factors impact corporate financial performance, cash flows, and enterprise value. Within ERM, these standards are crucial for quantifying and integrating non-financial risks, such as climate transition risks, into mainstream financial reporting. Unlike GRI standards, which focus on a company's external impacts, ISSB standards focus on how sustainability issues financially impact the company itself, making them complementary frameworks.

To apply ISSB standards in ERM, enterprises should follow three key steps. First, conduct a materiality assessment as per IFRS S1 to identify sustainability risks and opportunities across the value chain that materially affect enterprise value. Second, establish a robust governance structure, integrating oversight of these risks into board and management functions and embedding them in corporate strategy. Third, quantify and disclose key metrics, such as Scope 1, 2, and 3 GHG emissions, and assess financial impacts under various climate scenarios as guided by IFRS S2. For example, a major Taiwanese semiconductor firm adopted these standards, identified critical transition risks in its supply chain through Scope 3 analysis, and improved its ESG rating by 15% within a year.

Taiwanese enterprises face three primary challenges in adopting ISSB standards. First, ensuring data completeness and reliability, especially for Scope 3 GHG emissions from complex supply chains. Second, a shortage of interdisciplinary talent with expertise in both finance and sustainability, which is crucial for the required cross-departmental collaboration. Third, aligning ISSB requirements with existing local regulations, such as the FSC's 'Sustainable Development Roadmap,' to avoid redundant reporting. To overcome these, companies should prioritize investing in digital platforms for supply chain data collection, form a dedicated cross-functional sustainability task force supported by external experts, and conduct a gap analysis to create a unified reporting framework.
