Türkiye Sustainability Reporting Standards (TSRS)
Effective 1 January 2024, Türkiye's Turkey Sustainability Reporting Standards (TSRS) establish the national baseline for sustainability reporting. Issued by the Public Oversight, Accounting and Auditing Standards Authority (KGK) and grounded in the ISSB's IFRS S1 and S2, TSRS requires in-scope companies to disclose decision-useful information on sustainability-related risks, opportunities and climate matters. The standards are designed for interoperability with leading frameworks, enabling consistent, comparable and assurance-ready disclosures and supporting access to sustainable finance.
Standardising and improving sustainability reporting in Turkey to ensure that information is relevant, comparable and reliable for investors and other users of general-purpose financial statements. Linking sustainability aspects to cash flows, access to finance and cost of capital. Supporting competitiveness by enabling Turkish companies to meet increasing disclosure expectations (e.g., EU partners under CSRD, finance linked to the EU Taxonomy) with a consistent, audit-ready framework. TSRS is not an additional package; it enhances governance quality, data discipline and market confidence by integrating sustainability into the core corporate reporting suite.
TSRS applies to entities within the regulatory perimeter set by KGK, including companies that exceed at least two of the following for two consecutive reporting periods:
Total assets > TRY 500 million
Annual net sales > TRY 1 billion
It also captures certain public interest entities (e.g., regulated by SPK/BDDK/SEDDK, listed companies), and banks subject to BDDK (excluding TMSF banks), regardless of thresholds.
TSRS sustainability disclosures are prepared alongside annual financial statements and are subject to independent assurance by KGK-authorised auditors.
For now, TSRS consists of two standards; TSRS 1 (General Requirements) and TSRS 2 (Climate-related Disclosures)—applied together and structured around four pillars: Governance - Explain oversight, roles, processes, and controls used to monitor and manage sustainability and climate risks/opportunities. Strategy - Describe how identified risks/opportunities affect the business model and value chain; disclose resilience, transition plans, scenario analysis within the short/medium/long term time horizons. Risk Management - Set out how risks/opportunities are identified, assessed, prioritised, and monitored, and how these processes integrate with the enterprise risk framework. Metrics & Targets - Disclose metrics and targets (whether voluntary or legally required), methods, boundaries (including value chain), progress, and data quality considerations.
“TSRS turns sustainability into reporting discipline and financial relevance. Meeting the standard isn't just compliance—it's how Turkish companies build credibility, comparability, and resilience in domestic and international markets.“
Conduct a gap assessment against TSRS 1 & 2; map current ESG data/processes to required disclosures. Build a data model and controls (collection, validation, consolidation, evidence packs) that can withstand assurance. Clarify roles and accountability across sustainability, finance, risk, and IT; plan a phased roadmap to full compliance. For companies in EU-linked value chains, leverage TSRS alignment to bridge to ESRS/GRI where counterparties request it—minimising duplication and accelerating access to capital.
