IFRS S1 & S2 Sustainability Disclosures form the global baseline for investor-grade ESG reporting. For UAE private companies, early alignment builds credible data, embeds climate risk into strategy, and prepares for 2026 assurance. This roadmap sets the UAE context, explains the rules, and maps an audit-ready path to compliance.
The 2026 Finish Line
The ISSB issued IFRS S1 (general sustainability disclosure requirements) and IFRS S2 (climate) in June 2023, effective for reporting periods beginning 1 January 2024. IOSCO endorsed the standards and urged regulators to consider adoption, accelerating global uptake and investor expectations.
In the UAE, listed markets already require sustainability reporting, and free zone rules are moving toward globally recognised frameworks. Private companies face rising pressure from banks and counterparties for comparable, verifiable disclosures. They should expect external assurance to become the norm by 2026.
Where IFRS S1 & S2 Fit in the UAE Rulebook (and What That Means for Private Firms)
UAE exchanges and regulators have built an ESG foundation—most visibly through SCA-linked guidance and ADX/DFM programmes—while the UAE Sustainable Finance Working Group (SFWG) has issued Principles for Sustainability-Related Disclosures for financial sector entities. IFRS S1 & S2 add a financial-materiality lens that investors prefer, and they expect connectivity to the financials.
Context for the table below: Companies ask whether they must “switch” from GRI-style reporting to ISSB. In practice, most UAE groups will map and layer, keeping impact-oriented disclosures where required (e.g., exchange guidance), while adding the ISSB’s investor-focused, financially material content.
UAE Frameworks vs IFRS S1 & S2 (What Changes in Practice)
| Area | UAE listed companies rules (onshore & exchanges) | IFRS S1 & S2 (ISSB) | What this means for UAE private firms |
|---|---|---|---|
| Who’s in scope today | Onshore PJSCs must publish sustainability reports; ADX provides mandatory reporting guidance & indicator sets; DFM provides reporting guides. | Voluntary unless/until mandated; widely expected by investors & lenders. | Even if unlisted, banks and partners will expect ISSB-aligned packs by 2026. |
| Materiality lens | Emphasis traditionally aligned to GRI/impact with exchange indicator sets. | Financial materiality (enterprise value) with TCFD-style pillars. | Keep impact disclosures if required; add investor-grade, financially material ISSB content. |
| Placement | Exchange-driven sustainability reports; practices vary by issuer. | Disclosures connected to the financial report and decision-useful for investors. | Plan for integrated timelines with finance and cross-referencing. |
| Assurance | No universal statutory audit today on sustainability reports. | Designed for assurance; transitional “climate-first” relief available in year one. | Build audit-ready data, controls, and evidence packs for 2026. |
2026 Assurance: What It Means and When To Act
Assurance means an independent provider tests your sustainability data and narrative. ISSB designed S1/S2 for verifiability, and the Foundation has published transition relief; you may report climate first (IFRS S2) in your initial year while still applying related S1 requirements. Plan your cadence now so 2025 becomes the “rehearsal” and 2026 carries the assurance opinion.
Why a milestone table? Teams need a single page to align budgets, owners and audit evidence. The table below is intentionally concise so CFOs and CSOs can plan together.
UAE-Ready Milestones to Reach Assurance in 2026
| Quarter & deliverable | Accountable owner | Evidence an auditor will expect |
|---|---|---|
| Q4-2024: Gap assessment vs S1/S2; plan climate-first relief if needed | CFO + Sustainability lead | Written gap log; materiality memo; reporting plan with scope, boundaries, and reliefs |
| H1-2025: Data systems and control design; scenario-analysis approach for S2 | Finance controls + Risk | Data lineage diagrams; control matrices; scenario methodology papers |
| Q3-2025: Draft pilot S1/S2 disclosures; internal review | Disclosure committee | Draft disclosures tied to materiality; cross-references to financials |
| Q4-2025: Integrate with annual report; management sign-offs | CFO + Board committee | Consistency checks (MD&A/notes); management representation on ESG data |
| H1-2026: Pre-assurance walkthroughs; fix gaps | Internal audit + Process owners | Control testing results; remediation logs; updated workpapers |
| Q4-2026: Publish S1/S2 with limited assurance opinion | External assurance provider | Final evidence pack; signed assurance report; management responses if needed |
Materiality, Scope and Boundaries
Under IFRS S1, you disclose sustainability-related risks and opportunities that could reasonably affect enterprise value. That can include climate, as well as topics such as water risk in manufacturing or data privacy in services, if financially material.
Document the why: criteria, thresholds and evidence supporting your judgement, because auditors will review it. For boundary setting, include significant JVs and material value-chain exposures; expect to gather data from suppliers where Scope 3 categories are likely material.
Governance, Strategy and Risk
Investors want to see who is accountable, how climate/ESG risks are incorporated into the risk register, and how the strategy holds up under different scenarios. IFRS S2 requires disclosure across governance, strategy, risk management and metrics & targets, including scenario analysis that tests resilience (for example, 1.5°C and 2°C pathways). Be explicit about oversight (board/committee), management responsibilities, and escalation routes into enterprise risk management.
Metrics and Targets Under IFRS S1 & S2 Sustainability Disclosures
For climate, expect Scopes 1, 2 and—if material—Scope 3. If you use carbon credits, explain the type and basis of any reliance. Across industries, the ISSB directs companies to industry-specific guidance (SASB) so that peers disclose comparable metrics (e.g., building energy intensity in the real estate sector; financed emissions in financials). Set baselines and interim checkpoints, and link climate targets to the UAE’s wider transition policies where relevant.
Why a compact list here? Readers consistently ask, “What will we actually measure?” This short list reduces ambiguity.
- Climate metrics: Scopes 1–3 (where material), energy intensity, and transition-plan progress indicators.
- Industry metrics: Use SASB/industry-based guidance to select decision-useful measures by sector.
- Targets: State baselines, interim dates, and methods; demonstrate whether targets align with legal/market obligations in the UAE.
Data systems and Controls for IFRS S1 & S2: From Source to Assurance
Treat sustainability data like financial data. Map source-to-report lineage, assign data owners, and embed control activities (validations, reconciliations, segregation of duties). Keep a methodology book explaining emission factors, boundaries, estimation techniques and materiality decisions. This is the “evidence pack” your assurer will test—alongside consistency checks between sustainability narratives and financial statements.
Evidence pack—kept deliberately short so teams use it:
- Method memos for each metric
- Calculation workbooks with change logs
- Data extracts and sign-offs
- Control testing records
- Consistency ties to MD&A/financial notes
Two team playbooks that work in UAE businesses
Finance team: own the timetable, extend internal controls to non-financial data, quantify financial effects (e.g., impairment/opex impacts of climate risks), and coordinate with the external auditor so sustainability testing aligns with year-end.
Sustainability team: run materiality, lead supplier engagement for Scope 3, manage scenario analysis and the narrative, and train data owners across operations.
Together, they deliver a single, connected report rather than two separate documents.
Closing the gaps that trip up UAE filers (and how to fix them fast)
Scope 3 blind spots. Many footprints sit upstream. Start with the most material categories, be transparent on estimation methods, and then improve data quality through supplier engagement in 2025–2026.
Framework fatigue. Exchanges in the UAE set indicator expectations, while ISSB adds the investor lens. Create one core dataset and map it to both exchange guidance and ISSB to avoid duplication.
Targets without capex. Link net-zero and efficiency targets to budgets and timelines; explain dependencies on UAE policy instruments such as the National Register for Carbon Credits (where relevant).
Short UAE Scenarios You Can Benchmark Against
A family-owned industrial group discovers in a 2025 pilot that around 70% of emissions sit in raw-material suppliers.
It prioritises purchased goods and logistics, pilots primary data with top vendors, and documents estimation factors. The 2026 report shows improved coverage and a credible reduction plan disclosed under S2.
A regional services firm maps industry-based guidance to workforce safety and data-privacy metrics, adding rates and incident metrics investors can compare with peers. Assurance focuses on definitions, data lineage, and consistency between risk factors and the sustainability section.
An ADGM–registered SME uses the free zone’s comply-or-explain framework to publish a compact S2-first disclosure in 2025, then broadens to S1 topics in 2026 with limited assurance, all aligned to accepted global standards highlighted by ADGM.
IFRS S1 & S2 Sustainability Disclosures: How UAE Policy is Evolving Around You
Two federal instruments signal where the market is heading: Federal Decree-Law No. 11 of 2024 on the Reduction of Climate Change Effects establishes climate-governance foundations, while Cabinet Resolution No. 67 of 2024 creates the National Register for Carbon Credits (effective 28 Dec 2024). These don’t replace corporate reporting standards, but they create governance and market infrastructure that reporting will reference, particularly transition plans and carbon-market disclosures.
At the supervisory level, the UAE Sustainable Finance Working Group released Disclosure Principles for financial-sector reporting entities in 2024, another signpost that UAE authorities are aligning toward transparent, investor-relevant disclosures that dovetail with global baselines.

FAQs
Are IFRS S1 & S2 Sustainability Disclosures mandatory in the UAE for private companies?
Not yet as a blanket requirement. But exchanges already require listed issuers to report sustainability information, ADGM’s framework recognises globally accepted standards, and IOSCO’s endorsement has raised market expectations. Banks and investors now look for ISSB-aligned packs.
Can we adopt an S2-first approach in 2025?
Yes. ISSB’s climate-first transition relief allows entities, in their first year, to report only climate information in accordance with S2 while applying related S1 requirements, then broaden in year two.
Do we still need GRI-style content?
If your exchange or stakeholders expect impact disclosures, keep them, then layer ISSB for the investor lens. Use one dataset and map to both to avoid duplication.
What’s the minimum evidence for assurance in 2026?
Method papers, calculation workbooks with change logs, primary data extracts and sign-offs, tested controls, and documented tie-outs to the financials and risk factors.
Do UAE policies impact transition plans or carbon credit disclosures?
Yes. If you intend to use credits, please disclose how and why. The National Register for Carbon Credits provides local market infrastructure that you may reference in your plan.
