Introduction
Saudi-listed companies have spent the last three years hearing the same warning from auditors and investors: global sustainability reporting standards are coming, and Saudi Arabia will not be exempt forever. What's harder to find is a straight answer to a simple question — what exactly is mandatory today, what is only guidance, and who in the Kingdom actually decides when that changes?
This guide answers that question directly, using only what the Capital Market Authority (CMA), the Saudi Exchange (Tadawul), and the Saudi Organization for Chartered and Professional Accountants (SOCPA) have themselves published — not secondary commentary. It covers where IFRS S1 and IFRS S2 (the International Sustainability Standards Board's climate and general sustainability disclosure standards) currently stand in the Kingdom, what Tadawul's ESG Disclosure Guidelines already ask of listed companies, and a practical readiness checklist for compliance, IR, and finance teams who want to be ahead of a mandate rather than behind one.
What IFRS S1 and S2 Actually Are
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 International Sustainability Standards Board (ISSB), a body created under the IFRS Foundation in 2021. Together they require a company to disclose the sustainability- and climate-related risks and opportunities that could reasonably be expected to affect its cash flows, financing, or cost of capital over the short, medium, and long term — governance, strategy, risk management, and metrics/targets, mirroring the structure investors already know from the TCFD framework.
Over 30 jurisdictions worldwide have now set a mandatory or phased adoption timeline for IFRS S1/S2. Saudi Arabia has not yet joined that group with a binding date — but the groundwork is already underway, and that is the part most local commentary skips over.
Where Saudi Arabia Stands Today: SOCPA, CMA, and Tadawul
Three different Saudi bodies touch this topic, and each is at a different stage. Conflating them is the single most common mistake in secondary commentary on this subject — the kind of cross-regulator confusion covered more broadly in our Regulatory Compliance Saudi Arabia: Global GRC Strategies guide — so each is verified separately below against its own primary source.
SOCPA: translation and standard-setting groundwork, no mandate yet
SOCPA — the body responsible for adopting international accounting and auditing standards for use in the Kingdom — signed an agreement with the IFRS Foundation to produce official Arabic translations of the ISSB's sustainability standards, and continues to participate in the ISSB's Sustainability Standards Advisory Forum.

As of this writing, SOCPA has not published a board decision setting a mandatory or phased adoption date for IFRS S1/S2, unlike its recent, dated decisions on IFRS 18 and ISA 570 (Revised). Translation and advisory-forum participation are necessary precursors to adoption, not adoption itself — a distinction worth making explicitly to management, because "SOCPA is working on ISSB standards" is true, but does not mean a filing deadline exists yet.
CMA: focused on IFRS 18 in 2026, not yet on sustainability standards
Separately, the CMA has been active on financial-reporting standards in 2026 — but specifically on IFRS 18 (Presentation and Disclosure in Financial Statements), not the ISSB's sustainability standards. Listed joint-stock companies may voluntarily early-adopt IFRS 18 during 2026, must disclose preliminary impact assessments from 1 April 2026 onward, and face mandatory application for financial periods beginning 1 January 2027.

It is easy to see "CMA," "2026," and "mandatory" in the same sentence and assume it applies to ESG/sustainability disclosure. It does not — this CMA decision is about financial statement presentation, and has no bearing on IFRS S1/S2 adoption.
Tadawul: a live, working ESG Disclosure Guidelines resource — but explicitly voluntary
The Saudi Exchange has published its own ESG Disclosure Guidelines as "a useful resource for listed companies to help them navigate ESG," built as part of Tadawul's membership in the UN Sustainable Stock Exchanges Initiative since 2018.
Source: Saudi Exchange — ESG Guidelines
These guidelines are the closest thing to an official Saudi ESG disclosure framework in active use today, and they are the right starting point for a company building its first ESG disclosure — but they are guidance, not a listing requirement enforced with penalties, and they are not the same instrument as IFRS S1/S2.
Regulatory Status at a Glance
| Body | What it has done | Current status | Binding deadline? |
|---|---|---|---|
| SOCPA | Signed IFRS Foundation translation agreement; participates in ISSB advisory forum | Standard-setting groundwork | None published |
| CMA | Approved early/mandatory adoption of IFRS 18 (financial statements) | Active 2026 timeline — but for IFRS 18, not sustainability standards | 1 Jan 2027 (IFRS 18 only) |
| Tadawul (Saudi Exchange) | Published ESG Disclosure Guidelines for listed issuers | Voluntary guidance in active use | None — voluntary |
Why This Still Matters Even Without a Mandate
A missing deadline is not the same as no exposure. Three forces are already pushing Saudi-listed and pre-IPO companies toward ISSB-aligned disclosure ahead of any CMA mandate:
-
Investor and lender pressure. International institutional investors and green-financing lenders increasingly request IFRS S1/S2-aligned disclosure as a condition of allocation or preferential financing terms, independent of what the local regulator requires.
-
Vision 2030 sustainability commitments. The Kingdom's own Vision 2030 sustainability agenda creates a policy direction that companies who move early are better positioned to benefit from — in tenders, in listing reviews, and in ESG-linked capital access more broadly (a dynamic Saudi Compliance Institute has covered separately in ESG Scores Are Now Deciding Which Saudi Firms Attract Capital).
-
A predictable regulatory sequence. Jurisdictions that follow the SOCPA/CMA pattern seen with IFRS 18 — translation and advisory participation, then a board decision with an early-adoption window, then a mandatory date — tend to give the market 12–24 months of visible groundwork before a mandate lands. That groundwork is visibly underway now.
Readiness Checklist: What to Do Before a Mandate Exists
-
Map your current disclosure against Tadawul's ESG Disclosure Guidelines first. It is the only live, Saudi-specific ESG disclosure resource with any regulatory backing today — treat gaps against it as your baseline gap analysis.
-
Assign clear ownership and build the in-house skill for it. Identify who in finance, IR, and sustainability/HSE would own IFRS S1/S2 reporting if it became mandatory tomorrow — most companies discover this is nobody's job until asked, which is why ESG certification for the named owner (not just general awareness training) matters.
-
Inventory climate-related financial exposure. IFRS S2 specifically requires quantifying climate risk exposure to cash flows and cost of capital — this typically takes longer to assemble than any other part of the standard, so start the data-gathering exercise now, independent of a filing deadline.
-
Track SOCPA and CMA announcements directly, not through secondary commentary — a translation agreement or advisory-forum update is not the same as a mandate, and treating one as the other either causes needless panic or, worse, missed genuine deadlines.
-
Build governance and metrics disclosure in parallel with climate metrics. IFRS S1's governance and strategy disclosures are frequently the fastest to prepare and the easiest to demonstrate progress on to a board or investor before the harder climate-metrics work is finished.
-
Revisit this position quarterly. Given the pace of ISSB adoption globally (30+ jurisdictions and counting) and the CMA's demonstrated willingness to move quickly once it decides to act (as shown with IFRS 18's compressed 2026–2027 timeline), this is not a "set and forget" compliance question.
What Happens If You Wait
Because there is currently no binding IFRS S1/S2 deadline, there is no direct penalty exposure today for non-disclosure — but "no penalty yet" is a different risk than "no risk." Companies that wait until a CMA mandate is announced typically face a compressed adoption window modeled on regulatory precedent elsewhere in the Kingdom, where early-adoption periods have run 9–15 months before mandatory application (see ZATCA Penalties in 2026 for how compressed compliance windows have played out in a different Saudi regulatory context). Building climate-risk data infrastructure inside a compressed window, rather than ahead of one, is where most of the real cost and disruption sits.
Conclusion
The honest answer to "is ESG reporting mandatory in Saudi Arabia" is: not yet, but the groundwork for that to change is already visible in SOCPA's and Tadawul's own public record, and CMA has just shown — with IFRS 18 — how quickly it can move from "early adoption window" to "mandatory" once it decides to act. Companies that treat Tadawul's existing ESG Disclosure Guidelines as their baseline, assign real ownership, and start the climate-data groundwork now will not be caught in a compressed compliance window later. Our Environmental, Social, and Governance Certificate is built around exactly this readiness gap — practical, Saudi-specific ESG reporting skills your team can apply immediately, regardless of when a formal mandate lands.
