지속가능성 공시의 국제표준화와 회계정보 유용성：ISSB 기준의 한계와 국내 ESG 공시제도의 대응 방향

[Purpose]This study examines the structural characteristics and limitations of sustainability disclosure standards issued by the International Sustainability Standards Board (ISSB) from the perspective of accounting information usefulness, and aims to propose appropriate policy directions for ESG disclosure in Korea. [Methodology]To achieve this objective, the study reviews the background and key contents of the ISSB standards, IFRS S1 and IFRS S2, and conducts a comparative analysis of ESG disclosure regimes in the United States and Europe. In particular, the study focuses on differences in disclosure philosophy and institutional design between the investor－oriented single materiality approach and the double materiality approach. [Findings]The findings indicate that while the ISSB standards have significance as a global baseline that enhances international comparability, they have limitations in adequately reflecting country－ and industry－specific characteristics. In addition, requiring sustainability－related information to be disclosed as part of general－purpose financial reports may increase firms’ disclosure burdens and legal risks. [Implications]This study suggests that Korea should adopt a phased and strategic approach to ESG disclosure, rather than fully adopting the ISSB standards, by balancing international alignment with domestic applicability.
