What are IFRS S1 and IFRS S2?
IFRS S1 (General Requirements for Disclosure of Sustainability-related Financial Information) and IFRS S2 (Climate-related Disclosures) are the first two standards issued by the ISSB in June 2023. They establish the baseline for sustainability disclosures aligned with capital-markets needs. Both apply to annual reporting periods beginning on or after 1 January 2024.
IFRS S1 — General Requirements
- Governance: how the entity oversees sustainability-related risks and opportunities.
- Strategy: business model and value chain effects, anticipated financial effects.
- Risk management: processes for identifying, assessing, prioritising and monitoring.
- Metrics and targets: disclosure of performance metrics.
- Connectivity: sustainability disclosures must be linked to financial statements (consistent assumptions, time horizons).
IFRS S2 — Climate Disclosures
- Physical and transition risks: identification and impacts on strategy and financials.
- GHG emissions: Scope 1, 2 and material Scope 3.
- Climate-related opportunities.
- Industry-specific metrics: based on SASB Standards for the entity’s industry.
- Climate resilience: scenario analysis disclosure.
Türkiye’de uygulama
KGK (Kamu Gözetimi Kurumu) IFRS S1/S2’yi TFRS S1/S2 olarak Türkçeye çevirip yayınlamıştır. SPK’nın halka açık şirketler için sürdürülebilirlik raporlama zorunluluğu IFRS S1/S2 uyumlu çerçevede kademeli olarak uygulanıyor. KAP’a sunulan raporlar bu standartlara hizalanmalı.
Do: begin with IFRS S2 climate baseline; expand to broader IFRS S1 sustainability topics as data systems mature.
Don’t: treat IFRS S1/S2 as standalone — they connect to and depend on the same governance, internal control and audit infrastructure as financial reporting.
