Korea KSSB disclosure
KSSB Sustainability Disclosure Standards and FSC roadmap (Capital Markets Act amendment bill)
Topic : ESG disclosure · Level : National
Today
Roadmap 8 Jul 2026: KOSPI ≥KRW10tn assets report FY2027 (filed 2028). FSCMA bills filed Mar and 5 Aug 2026; not passed.
Summary
Korea's KSSB standards were finalised in Feb 2026 but remain voluntary. A July 2026 roadmap makes climate disclosure mandatory for KOSPI firms with KRW10tn+ assets from FY2027 reports, then KRW5tn+. The enabling bill was filed in Aug 2026. Scope 3 starts 2031.

Scope 3 from 2031 will require supplier emissions data, including Chinese suppliers.
- Examples
- Korean battery maker with China cathode suppliers
- Korean shipbuilder buying Chinese steel
- Electronics chaebol affiliate
What the law requires
- Disclose climate information in statutory business reports under KSSB standards
- Report Scope 1 and 2 emissions from first year; Scope 3 after a 3-year grace period
- Obtain third-party assurance from 2030 by FSC-registered bodies (framework to be set)
Penalties
First 3 years: no FSCMA damages, administrative or criminal liability except intentional false disclosure. Then safe harbor for estimates.
What this changes for a supplier in China
No near-term direct change. Korean buyers will need supplier Scope 3 data from 2031; early data requests likely during 2026 pilots.
Expected evidence
- Scope 1-2 GHG inventory
- Product carbon footprint for supplied goods
- Energy and electricity data
