The Financial Services Commission announces an expanded and accelerated timetable for mandatory ESG disclosures, covering a broader range of listed companies from 2028 to meet investor demands and climate goals.
South Korea has taken a firmer line on corporate sustainability reporting, with the Financial Services Commission confirming on 8 July 2026 that mandatory ESG disclosure will reach a far broader group of listed companies than originally envisaged. The revised roadmap moves the starting point to KOSPI-listed firms with consolidated assets of KRW10 trillion or more from fiscal year 2028, before lowering the threshold to KRW5 trillion in fiscal year 2029 and KRW2 trillion in fiscal year 2030.

The shift marks a significant expansion from the draft plan published in February, which had proposed a much narrower first wave of reporting by only the very largest companies. According to the FSC, the scope was widened after institutional investors pressed for more extensive sustainability data, arguing that it would be useful for investment decision-making. (fsc.go.kr)
The new timetable is also more aligned with Korea’s broader policy direction on climate and capital markets. The country’s sustainability standards, developed by the Korea Sustainability Standards Board, are based on the International Sustainability Standards Board framework and mirror the ISSB’s IFRS S1 and IFRS S2 requirements on general sustainability-related and climate-related disclosures. (fsc.go.kr)
Under the final roadmap, the first wave of companies will begin filing sustainability disclosures in 2028, covering fiscal year 2027 data, with the regime then widening in 2029 and again in 2030. The FSC said it will review market conditions and disclosure practices in 2028 and 2029 before deciding whether to bring the threshold down further, to KRW2 trillion from 2030. (fsc.go.kr)
The commission said the change means the number of firms in scope will rise sharply. More than 290 companies are expected to be covered at the first stage, increasing to more than 3,100 the following year. For industrial groups, the implications are substantial: many medium and large manufacturers, exporters and supply-chain heavy businesses will now need to prepare for structured sustainability reporting far earlier than under the original draft. (fsc.go.kr)
To ease the transition, the FSC has introduced a series of relief measures. Scope 3 emissions disclosure will be deferred for three years after the start of mandatory reporting, and smaller firms that are not considered high-carbon emitters may be exempted from that requirement altogether. The first three years will also come with protections against damages claims, administrative penalties and criminal punishment related to the content of sustainability disclosures, although the commission said intentional greenwashing would still be dealt with firmly. (fsc.go.kr)
Third-party assurance will ultimately become part of the regime, but not until 2030. In the meantime, companies not yet legally bound to report will be encouraged to file disclosures voluntarily through the Korea Exchange, whose system is being updated to accommodate KSSB-aligned reporting. (fsc.go.kr)
The roadmap comes as Seoul intensifies preparations for wider climate-related compliance across industry. The FSC said the government is also planning support measures including consulting for ESG management and disclosure processes, while the Ministry of Climate, Energy and Environment is developing climate-risk infrastructure and sector-specific scope 3 guidance for 15 key export industries. For industrial decarbonisation teams, that points to a more coordinated reporting environment in which emissions accounting, supply-chain data and transition planning are increasingly likely to converge.

The consultation period for this draft roadmap ended on March 31, 2026. Under the draft roadmap, companies listed on the Korea Composite Stock Price Index (KOSPI) with consolidated total assets of KRW 30 trillion or more would be required to provide information in line with the Korean sustainability reporting standards from fiscal year 2027 onwards.

Under the proposal, companies listed on the Korea Composite Stock Price Index (KOSPI) with consolidated assets of KRW 30 trillion or more would begin reporting under KSSB 1 (General Requirements) and KSSB 2 (Climate-related Disclosures) from fiscal year 2027, with the scope expanding to companies with assets of KRW 10 trillion or more from 2028. Smaller subsidiaries would initially be exempt, as would small companies in the value chain, while Scope 3 emissions disclosures would only become mandatory from 2030.

The Korea Sustainability Standards Board (KSSB) released the country’s first sustainability disclosure standards on February 26, 2026, aligning with global ESG disclosure frameworks increasingly shaped by ISSB-related standards.
