Summary
Turkey made ISSB-based TSRS reporting mandatory for large entities from 2024. In January 2026 the KGK raised the thresholds to two of: TRY 1bn assets, TRY 2bn sales, 500 employees. Borsa Istanbul's guide stays voluntary.

Turkish entities only; value-chain data (Scope 3 under TSRS 2) flows to foreign suppliers.
- Examples
- Turkish textile exporter with 800 staff
- Borsa Istanbul-listed automotive supplier
What the law requires
- Prepare sustainability report under TSRS 1 and TSRS 2 (IFRS S1/S2)
- Disclose Scope 1, 2 and, after relief, Scope 3 emissions
- Obtain independent assurance from a KGK-authorised auditor
Penalties
No TSRS-specific fines. Non-filing breaches the KGK decision (TTK art. 88); board liability under TTK art. 553; CMB rules on misleading disclosure.
What this changes for a supplier in China
Turkish textile, auto and appliance makers buy heavily from China. Their TSRS 2 Scope 3 work drives data requests to Chinese yarn, component and chemical suppliers.
Expected evidence
