Kuwait Makes ESG Reporting Mandatory: The 30 June 2026 Boursa Deadline

Updated 20 October 2026: the legal basis is now given as CMA Circular No. 04 of 2025 under Article 1-17-4 of Module Twelve, the Boursa Kuwait 2026 guide is shown as advisory with its framework, Scope 3, scenario analysis and double materiality content as recommendations, and the deadline is updated now that the first cycle has closed.

Introduction

Kuwait has made sustainability reporting a regulatory requirement for its largest listed companies. Under CMA Circular No. 04 of 2025 (12 February 2025), companies on Boursa Kuwait’s Premier Market must publish a sustainability report each year, starting with the 2025 financial year. The first reports were due by the end of the second quarter: 30 June 2026 for calendar-year companies. The FY2026 report is next, due by 30 June 2027. This article sets out who is in scope, what the rule demands, and what a compliant, credible report looks like.

From voluntary guidance to a mandate

Boursa Kuwait has published an ESG reporting guide since 2023, and listed companies could already report voluntarily under Article 1-17 of the CMA Executive Bylaws. The mandate came from the CMA, not from the guide. CMA Circular No. 04 of 2025, issued under Article 1-17-4 of Module Twelve (the Listing Rules), made the report mandatory for Premier Market companies, and Boursa Kuwait wrote it into Rulebook Article 7-8-1(6) (July 2025) as a continuing listing obligation. Article 1-17-3, sometimes cited as the basis, only requires Boursa to prepare the guide. The ESG Reporting Guide, 2026 Edition (released 15 March 2026) keeps its advisory status.

Who is in scope

The mandate applies to Premier Market companies only, Boursa Kuwait’s flagship tier of the largest, most liquid issuers. In practice that captures the country’s systemically important names: the major banks (National Bank of Kuwait, Kuwait Finance House, Boubyan Bank, Gulf Bank, Burgan Bank, Warba Bank, Al Ahli Bank of Kuwait, GFH Bank), large caps such as Zain and Mabanee, and the companies promoted into the tier at the latest annual review (International Financial Advisors, United Real Estate, Combined Group Contracting and First Fuel). The Premier Market roster, in the low twenties of companies, is refreshed at each annual review, so issuers near the threshold should assume they may be next. Main Market and Emerging Companies Market issuers may report voluntarily.

Banks carry a second instrument. Central Bank of Kuwait Circular No. 2/BS, IBS/500/2022 (16 November 2022) directs local banks to issue an annual sustainability report or a sustainability section in the annual report, and to identify and measure climate risk in the ICAAP.

What the disclosure requires

Article 1-17-2 sets the content. The report must be prepared under one or more international sustainability reporting standards, which the rule does not name. It must describe its scope and basis, identify the most important environmental, social and economic topics through a materiality assessment that involves stakeholders, explain the method, and describe how each material topic is managed.

The Boursa Kuwait ESG Reporting Guide, 2026 Edition, is the reference companies work from, and it is advisory:

• It describes GRI, SASB, TCFD, CDP and the ISSB standards (IFRS S1 and S2), and maps its recommended metrics to GRI and IFRS S1/S2. None of these frameworks is required, and the guide states that the ISSB standards are “not yet mandated in Kuwait”.
• It recommends a set of ESG metrics across the environmental, social and governance pillars. Scope 1 and 2 emissions are recommended for all companies; Scope 3 is recommended where material.
• It expands guidance on climate scenario analysis (which it says is “not yet mandatory in Kuwait”), transition planning and double materiality.
• External assurance is optional (Article 1-17-2(4)). A company that obtains it must include the assurance report in the sustainability report.

“

A first mandatory report is not a brochure with a green cover. It is an evidence file — and the auditors, regulators and investors reading it will treat it that way.

The legal minimum is a report under a recognised standard with a genuine materiality assessment. The guide goes further. Scope 3, scenario analysis and double materiality are the harder edges of modern disclosure, and they are what IFRS S1 and S2 require in Qatar today and in Oman from 2029. A Kuwaiti company that builds them now is building for the next rule, not the current one.

Kuwait in the GCC disclosure wave

Kuwait’s mandate is a filing obligation, not an ISSB mandate. Five of the six GCC states now make some sustainability report mandatory for listed companies; Saudi Arabia, where the Saudi Exchange (Tadawul) guidelines are voluntary, is the exception. Only Qatar has IFRS S1 and S2 in effect, through QFMA and the Qatar Central Bank from FY2026 (see IFRS S1 and S2 in Qatar), and Oman has adopted them from 1 January 2029. Kuwait has no adoption decision or roadmap. The full comparison is in ESG disclosure rules in the GCC, country by country. An issuer that builds ISSB-aligned capability now is meeting the Kuwaiti rule and preparing for the direction the region’s rules are moving.

What a compliant, credible report takes

1. Fix the reporting boundary so it matches the financial consolidation boundary; mismatches are the fastest route to a credibility problem.
2. Build the GHG inventory — Scope 1, 2 and material Scope 3 under the GHG Protocol, with an audit trail.
3. Run the harder analyses — climate scenario analysis and double materiality — rather than asserting them.
4. Design for assurance from the start. It is optional under the rule, but the numbers have to stand up when investors or the regulator ask.
5. Get the board engaged — mandatory disclosure is a governance matter, and the sign-off is now real.

How ESGweise helps

ESGweise builds ESG reports for GCC financial institutions and corporates to be both investor-ready and audit-ready, aligned to the Boursa Kuwait guide and to GRI and IFRS S1/S2, with the data architecture, materiality work and assurance readiness that a mandatory filing demands. With the FY2026 report due by 30 June 2027 for calendar-year companies, the priority is a controlled production cycle rather than a second-quarter scramble.

Conclusion

Kuwait has made sustainability reporting mandatory for its Premier Market companies. The first cycle closed on 30 June 2026 for calendar-year companies, and the FY2026 report is next. The rule sets a floor: a report under a recognised standard, with a genuine materiality assessment. The issuers that treat it as an evidence-backed discipline, and build to the guide’s recommendations rather than the minimum, will be ready if Kuwait follows Qatar and Oman to IFRS S1 and S2.
