Bahrain ESG Reporting: What CBB-Licensed Banks Must Know in 2026
Bahrain ESG Reporting: What CBB-Licensed Banks Must Know in 2026
Bahrain has moved ESG reporting from aspiration to obligation. The Central Bank of Bahrain (CBB) issued its Environmental, Social and Governance (ESG) requirements module in November 2023, making sustainability disclosure mandatory for all CBB-licensed banks, financing companies, insurance firms, and investment firms from financial year 2024 onwards.
If your institution is CBB-licensed and you have not yet built a structured ESG reporting programme, you are already behind. This article covers the framework requirements, the Islamic finance dimension, how Bahrain compares to Qatar and the UAE, and what your compliance team must do now.

What the CBB ESG Module Actually Requires
The CBB framework applies to all listed companies, banks, financing companies, insurance firms, and category 1 and 2 investment firms. Reporting started for financial year 2024. There is no phased-in grace period for CBB-licensed banks.
The Core Framework Structure
The CBB module draws primarily on the Global Reporting Initiative (GRI) Standards and incorporates Task Force on Climate-related Financial Disclosures (TCFD) guidance. The TCFD is a global framework, established by the Financial Stability Board, covering four core disclosure pillars: governance, strategy, risk management, and metrics and targets.
The module includes double materiality: entities must disclose both how ESG issues affect the business financially, and how the business affects the environment and society. This places the CBB framework closer to the European model than to the purely investor-focused ISSB approach used in Qatar.
Scope of emissions required under the CBB module:
- Scope 1: Direct greenhouse gas (GHG) emissions from sources owned or controlled by the entity.
- Scope 2: Indirect emissions from purchased electricity, heat, steam, or cooling.
- Scope 3: All other indirect value chain emissions, including financed emissions (Scope 3 Category 15) for banks and financial institutions. Financed emissions represent the GHG footprint embedded in a bank's loan book and investment portfolio. For most banks, financed emissions account for over 95% of their total carbon footprint.
Annual Reporting Obligation
Listed companies and CBB licensees must submit an ESG report annually. The report must incorporate the ESG Key Performance Indicators (KPIs) specified in Appendix 1 of the module. It can either be a standalone document or included within the annual report.
The Bahrain Bourse also publishes its own ESG Reporting Guide covering 32 ESG metrics. Banks operating as listed entities on Bahrain Bourse must align to both the CBB module and the Bourse guide simultaneously.

Is Bahrain Adopting ISSB IFRS S1 and S2?
IFRS S1 and IFRS S2 are the two International Sustainability Reporting Standards issued by the International Sustainability Standards Board (ISSB) in June 2023. IFRS S1 covers general sustainability-related financial disclosures; IFRS S2 covers climate-related disclosures specifically.
Bahrain has not yet mandated IFRS S1 and S2. The CBB currently requires banks to report in line with TCFD and ISSB guidance, but broader ISSB adoption remains voluntary as of mid-2026. The CBB module treats TCFD as a reference framework, not a standalone requirement. Banks choosing to align early with ISSB S1 and S2 are working ahead of the curve, and the direction of GCC regulatory travel makes that a defensible investment.
The comparison across the GCC:
Qatar's approach is more prescriptive: the Qatar Central Bank (QCB) and the Qatar Financial Centre Regulatory Authority (QFCRA) have both mandated full IFRS S1 and S2 for financial institutions from January 2026. Bahrain is at an earlier stage but is expected to converge toward ISSB as GCC frameworks harmonise. Banks that build ISSB-aligned data infrastructure now position themselves to absorb that transition at lower cost.
The Islamic Finance ESG Angle: Why Bahrain Is Central
Bahrain is one of the world's leading Islamic finance centres. According to the Islamic Finance Development Indicator (IFDI) Report 2025, Bahrain ranked eighth globally in Islamic finance, with the Cambridge Institute of Islamic Finance placing it fifth in 2024.

Islamic finance and ESG share structural principles: both exclude harmful activities, both emphasise social responsibility, and both require transparency on the use of capital. This alignment creates a commercial opportunity for Bahrain's CBB-licensed banks.
Green Sukuk and the ESG Reporting Connection
Green sukuk are Shariah-compliant fixed-income instruments where proceeds are restricted to climate-positive or environmentally beneficial projects. ESG sukuk global issuance has grown sharply in recent years. In 2020, issuers sold $4.8 billion of ESG sukuk. By 2024, that figure had risen to $15.2 billion according to LSEG data.
For Bahrain banks considering green sukuk issuance, credible ESG reporting is not optional. Investors and underwriters require verified ESG data. Bahrain's Infracorp, part of GFH, issued a $900 million green sukuk. That issuance depended on a credible ESG framework to attract investor capital. Robust ESG reporting, aligned with the CBB module, is the foundation that makes such capital market access possible. Our Green Sukuk & ESG Disclosure in the GCC guide covers the issuance requirements in detail.

The broader GCC sustainable finance market reinforces this pressure. S&P Global projects Middle East sustainable bond issuance to reach $20-25 billion in 2026, up from a 3% increase in 2025 against a 21% global decline. Sustainable sukuk volume in the Middle East reached a record $11.4 billion in 2025. Bahrain's banks that cannot demonstrate credible ESG data will find institutional capital increasingly difficult to access.

How CBB Requirements Compare to UAE and Qatar
The three frameworks differ in depth, reference standards, and enforcement context.
The UAE Climate Law (Federal Decree-Law No. 11/2024) mandates GHG reporting through the Ministry of Climate Change and Environment's (MOCCAE) own MRV methodology. It is primarily a Scope 1 and Scope 2 emissions reporting obligation, enforced via the mrv.ae platform. The first reporting deadline was 30 May 2026. It does not produce a full ISSB-compliant sustainability report on its own.
Qatar's QCB and QFCRA have adopted IFRS S1 and S2 as mandatory for banks and regulated financial institutions from January 2026. Qatar uses a dual-regulator model: the QCB governs onshore banks, while the QFCRA governs QFC-authorised firms under the GENE Rules 2025. A bank operating in both jurisdictions must comply with both simultaneously. Spectreco's detailed breakdown of the UAE Climate Law and GCC ESG requirements covers this in full.

Bahrain's CBB module sits between the two. It is more comprehensive than UAE's climate-focused MRV requirement because it covers full environmental, social, and governance disclosure. It is less prescriptive than Qatar's mandatory IFRS S1/S2 mandate because it draws on GRI and TCFD as frameworks without yet mandating full ISSB adoption.
For a financial institution operating across all three markets, a unified ESG data platform is the only practical solution. Building separate data silos per jurisdiction is a compliance and cost problem that compounds annually.
Five Steps CBB-Licensed Banks Must Take Now
- Conduct a gap assessment against the CBB ESG KPI Appendix. Map your current data availability against every required indicator. Identify which Scope 1, 2, and 3 data sources do not yet exist.
- Build your Scope 3 financed emissions methodology. Most banks have not started this. For Bahrain's Islamic banks, financed emissions attached to murabaha, ijara, and musharaka portfolios must be measured under the PCAF (Partnership for Carbon Accounting Financials) methodology. PCAF is the global standard for measuring GHG emissions associated with loans and investments.
- Align governance disclosures to TCFD structure. The CBB module references TCFD. That means board-level documentation of climate risk oversight, management accountability structures, and scenario analysis are required disclosures, not optional additions.
- Prepare for assurance. Bahrain Islamic Bank's 2024 sustainability report was audited by KPMG Fakhro and approved by the Board. Third-party verification is becoming market expectation, not just regulatory direction.
- Build toward ISSB alignment early. The GCC trajectory is clear. Qatar mandated IFRS S1 and S2 in 2026. Saudi Arabia is moving in the same direction. Bahrain will follow. Building ISSB-compatible data infrastructure today avoids an expensive rebuild in 12 to 18 months.
