What IFRS S2 requires of banks, why financed emissions and scenario analysis are the hard parts, and how GCC financial institutions should prepare.
Introduction
Climate disclosure for a bank is a different problem than for a factory. A factory reports its own emissions; a bank must report the emissions of everything it finances — and model how climate could reshape its entire portfolio. IFRS S2, the ISSB’s climate standard, is where those demands land. For GCC banks, with adoption advancing led by the Qatar Central Bank, it is fast becoming the baseline. This article explains what it requires and where the difficulty lies. It builds on our note on IFRS S1 and S2 in Qatar.
What IFRS S2 requires
IFRS S2 structures climate disclosure on the four TCFD pillars:
| Pillar | What banks must disclose |
|---|---|
| Governance | Board and management oversight of climate risk |
| Strategy | Climate risks/opportunities, scenario analysis, transition plan |
| Risk management | How climate risk is identified, assessed and managed |
| Metrics & targets | Scope 1, 2 and material Scope 3 (incl. financed emissions), targets |
For banks, two of these are genuinely hard: metrics (financed emissions) and strategy (scenario analysis).
The two hard parts
Financed emissions. IFRS S2 expects material Scope 3 — and for a bank, that means financed emissions (Category 15), its largest and most data-challenged source. Measuring them to a standard like PCAF, with honest data-quality disclosure, is the heaviest lift.
Scenario analysis. IFRS S2 expects climate scenario analysis — how the bank performs under different climate futures. That is analytical work, often NGFS-aligned, not a narrative.
For a bank, IFRS S2 is not a disclosure exercise. It is a data exercise with a disclosure at the end.
How GCC banks should prepare
The priority is the data foundation. Build financed-emissions measurement to PCAF; develop NGFS-aligned scenario analysis integrated with risk; establish board governance of climate; and design for assurance from the start. With the Qatar Central Bank mandating IFRS S1/S2 for banks from FY2026 and the region converging, early preparation turns the first mandatory cycle into a controlled process rather than a scramble.
How ESGweise helps
ESGweise helps GCC banks prepare for IFRS S2 — building financed-emissions measurement, NGFS-aligned scenario analysis, governance and assurance-ready data architecture, so the disclosure rests on real numbers. See our reporting and assurance practices, our work with banking and financial services, and our wider map of sustainable finance in the GCC.
Conclusion
IFRS S2 brings investor-grade climate disclosure to banks, structured on the TCFD pillars — but its hard edges, financed emissions and scenario analysis, are data problems, not writing problems. For GCC banks facing adoption led by the Qatar Central Bank, the institutions that build the data foundation now will report with confidence when the mandate lands.
Frequently asked questions
What does IFRS S2 require of banks?
IFRS S2 requires disclosure of climate-related risks and opportunities across four areas: governance, strategy, risk management, and metrics and targets. For banks specifically, it requires Scope 1, 2 and material Scope 3 emissions — including financed emissions (Category 15) — climate scenario analysis, and information on transition plans and resilience. It is the investor-grade climate-disclosure standard.
Why are financed emissions the hard part of IFRS S2 for banks?
Because financed emissions — the greenhouse gases attributable to a bank's lending and investment — are by far its largest emissions source, and the data is difficult to gather and varies in quality. Measuring them to a standard like PCAF, with honest data-quality disclosure, is the most demanding part of a bank's IFRS S2 reporting.
How does IFRS S2 relate to TCFD?
IFRS S2 builds directly on the TCFD recommendations and uses the same four-pillar structure — governance, strategy, risk management, and metrics and targets. The TCFD itself has been consolidated into the ISSB framework, so IFRS S2 is effectively the successor standard, now more prescriptive and globally consistent.
Are GCC banks required to adopt IFRS S2?
Adoption is advancing across the region. The Qatar Central Bank has moved to make IFRS S1/S2 mandatory for banks from FY2026, and other GCC regulators and exchanges are converging on the ISSB standards. Even where not yet mandatory, IFRS S2 is becoming the expected baseline for credible climate disclosure by GCC financial institutions.
