ComplianceSGX Climate Reporting and Board Diversity Rules
SGX RegCo’s climate-reporting reforms mandate phased TCFD-aligned disclosures, board diversity policies, and assurance expectations starting with FY2023 filings, demanding strong governance, data architecture, scenario analysis, and director training across listed issuers.
Editorially reviewed for factual accuracy
Executive summary. Singapore Exchange Regulation (SGX RegCo) confirmed on 15 December 2021 that climate-related disclosures aligned with the Task Force on Climate-related Financial Disclosures (TCFD) framework will become mandatory for issuers in phased cohorts beginning with financial, energy, and agriculture/food/forestry sectors for financial years starting in 2023, expanding to materials/buildings and transportation in 2024 and to all remaining issuers on a comply-or-explain basis thereafter. SGX simultaneously mandated board diversity policy disclosures, sustainability reporting assurance on a comply-or-explain basis, and improved sustainability training expectations for directors, signaling a significant escalation in environmental, social, and governance (ESG) governance obligations for listed companies in Singapore.
Regulatory architecture
The SGX Listing Rules (Mainboard) Rule 711A/B and Catalist Rule 711A/B now require issuers to prepare annual sustainability reports within five months of financial year-end, explicitly referencing TCFD’s four thematic pillars—governance, strategy, risk management, and metrics and targets—and to provide climate scenario analysis as soon as practicable. Board diversity disclosures are embedded in the corporate governance code, compelling issuers to publish diversity policies, objectives, and progress while explaining how diversity integrates with director nomination processes.
Key obligations
Listed issuers must:
- Deliver TCFD-aligned reports: Provide board and management oversight narratives, describe climate-related risks/opportunities across short, medium, and long horizons, and detail risk management processes including integration with enterprise risk management frameworks.
- Report metrics and targets: Disclose Scope 1 and Scope 2 greenhouse gas (GHG) emissions; include Scope 3 where material; set science-based or otherwise strong targets; and outline progress, baselines, and methodology.
- Do scenario analysis: Evaluate resilience against at least one 1.5°C or well-below 2°C transition scenario and relevant physical risk scenarios, summarizing assumptions, data sources, and financial impacts.
- Obtain assurance: Provide assurance over sustainability reporting (starting with the data most material to investors) or explain plans to secure assurance and improve data quality. Assurance providers must meet competency criteria outlined by SGX.
- Publish board diversity policies: Disclose measurable objectives, skills/experience matrices, gender/tenure/independence mix, and progress updates. Non-compliance must be justified.
- Train directors: Ensure boards receive sustainability training and disclose completion status.
Post-consultation outcome
On 9 July 2024 Parliament passed the Sustainability Reporting Bill, helping ACRA to mandate ISSB-aligned climate disclosures for large listed issuers from FY 2025 and large non-listed companies from FY 2027.
The Sustainability Reporting Act 2024 embeds SGX RegCo’s phased regime in law, introducing assurance requirements for greenhouse gas metrics and enforcement powers for deficient filings.
Early movers will differentiate in capital markets, meet lender ESG covenants, and mitigate compliance risk as climate reporting becomes a baseline expectation.
Regulatory framework
The Singapore Exchange (SGX) mandated climate-related disclosures for listed issuers beginning with financial years ending on or after 31 December 2022. The requirements align with recommendations of the Task Force on Climate-related Financial Disclosures (TCFD), covering governance, strategy, risk management, and metrics and targets. SGX's phased setup approach allows issuers time to build capabilities while ensuring meaningful disclosure progress.
Initial requirements focus on climate disclosure on a comply-or-explain basis, enabling issuers to explain challenges preventing full compliance while demonstrating good-faith efforts toward setup. Subsequent phases introduce mandatory reporting elements and improved disclosure expectations. SGX RegCo monitors compliance and guides to support issuer setup efforts.
TCFD alignment
Disclosures should address all four TCFD pillars. Governance disclosures describe board oversight and management's role in assessing and managing climate-related risks and opportunities. Strategy disclosures explain how climate-related risks and opportunities affect business, strategy, and financial planning, including scenario analysis where appropriate.
Risk management disclosures describe processes for identifying, assessing, and managing climate-related risks and how these integrate with overall risk management. Metrics and targets disclosures report greenhouse gas emissions, climate-related performance indicators, and targets used to manage climate-related risks and opportunities.
Industry-specific considerations
SGX recognizes that climate risks and reporting capabilities vary across industries and issuer sizes. The exchange guides supporting setup across different sectors, including references to industry-specific metrics and disclosure approaches. Issuers should assess which climate-related risks and opportunities are most material to their business and focus on disclosure as needed.
Financial institutions face particular expectations given their role in financing the economy and their exposure to transition risks through lending and investment portfolios. Real estate companies should address physical risks from climate change and energy efficiency of their property portfolios. Manufacturing and industrial companies should report on emissions-intensive processes and decarbonization plans.
Implementation approach
Issuers should establish governance frameworks assigning responsibility for climate disclosure to appropriate board committees and management functions. Integration with existing risk management and sustainability programs supports efficient setup. External expertise may be needed for technical aspects such as greenhouse gas accounting, scenario analysis, and target-setting.
Data collection infrastructure requires investment to capture emissions data across Scope 1, 2, and material Scope 3 categories. Many issuers begin with Scope 1 and 2 emissions before expanding to more complex Scope 3 categories. Data quality improvements over successive reporting cycles improve disclosure reliability and comparability.
Assurance considerations
While SGX has not mandated external assurance of climate disclosures initially, many issuers voluntarily obtain assurance to improve credibility. Internal audit functions can provide pre-assurance review of climate data and processes. As disclosure maturity increases, external assurance expectations may expand through regulatory requirements or investor pressure.
Control frameworks for climate data should address data capture, calculation methodologies, review procedures, and audit trails. Documentation supports both internal governance and external verification processes. Alignment with emerging assurance standards helps ensure readiness for potential mandatory assurance requirements.
Closing analysis
SGX's climate reporting mandate advances Singapore's position as a sustainable finance hub while providing investors with decision-useful climate information. Issuers should invest in governance frameworks, data infrastructure, and reporting capabilities to meet current requirements and prepare for improved expectations. Early engagement supports competitive positioning and stakeholder confidence in climate commitments.
Ongoing engagement with SGX RegCo and industry associations supports understanding of regulatory expectations and emerging good practices. Regular review of disclosure quality against peer benchmarks helps identify improvement opportunities. Investment in climate capabilities positions issuers for success in an now sustainability-focused investment environment.
Documentation of governance decisions and control effectiveness supports regulatory inquiries and audit processes. Training programs ensure staff understand their responsibilities under the climate reporting framework.
Assurance and Verification Requirements
SGX's climate reporting mandate introduces external assurance expectations for sustainability disclosures. Listed issuers must engage independent assurance providers to verify climate metrics and emission calculations. This requirement aligns Singapore with international trends toward mandatory sustainability assurance and increases reliability of reported data for investors and stakeholders.
Assurance engagements should follow recognized standards such as ISAE 3000 or ISAE 3410 for greenhouse gas statements. Organizations must establish internal controls and documentation supporting assurance procedures. Early engagement with assurance providers helps identify data gaps and process improvements needed before reporting deadlines.
Integration with Financial Reporting
Climate-related financial risks now require integration with traditional financial reporting. Organizations should assess how physical climate risks and transition risks affect asset valuations, impairment assessments, and going concern evaluations. Board oversight of climate risks must be documented and disclosed alongside traditional governance disclosures.
