South Korea Mandates ESG Disclosures for Large Firms Starting 2028
South Korea plans to implement mandatory environmental, social, and governance (ESG) disclosures for major corporations beginning in 2028. Companies with total assets of 10 trillion Korean won (approximately $6.5 billion) or more will be required to report on their ESG performance and associated risks. This initiative, announced by South Korean government and ruling Democratic Party officials, expands the scope of companies covered compared to earlier proposals. Specifically, firms listed on the Korea Composite Stock Price Index (KOSPI) with consolidated assets of at least 10 trillion won will need to publish ESG reports starting in 2028. The regulatory requirement will be further broadened in 2029 to include companies with consolidated assets of 5 trillion won or more.
South Korea's move to mandate ESG disclosures reflects a global trend toward greater corporate accountability in environmental and social impact. By setting a phased implementation starting with the largest companies and expanding over time, the government aims to balance the need for robust data with the capacity of businesses to adapt. This policy could enhance investor confidence and encourage sustainable business practices by providing standardized information. However, the effectiveness will depend on the clarity of disclosure standards, the rigor of oversight, and the potential for compliance costs to disproportionately affect smaller entities within the expanded scope. Over the next decade, such regulations are likely to become more common as stakeholders increasingly demand transparency on non-financial performance, potentially driving innovation in sustainable technologies and corporate governance models.
