Sustainability reporting and assurance requirements

All companies listed on the Singapore Exchange (SGX) need to report.

Requirements depend on your company's tier:

• Tier 1: Straits Times Index (STI) constituents

• Tier 2: Non-STI constituent listed companies with a market capitalisation of $1 billion and above

• Tier 3: Non-STI constituent listed companies with a market capitalisation of less than $1 billion

Large NLCos that meet both criteria need to report unless exempted:

• Annual revenue of $1 billion and above

• Total assets of $500 million and above

Exemption criteria

Your company may be exempted if both conditions are met:

• Your immediate, intermediate or ultimate parent company (local or foreign) is minimally preparing climate or sustainability reports using ISSB-based local reporting standards, or equivalent standards (see note); and

• Your company’s activities are included in your parent’s report which is available for public use.

Note: As international sustainability disclosure standards constantly evolve, ACRA will issue guidance on equivalent standards to guide implementation.

Note: For all other non-STI constituent listed companies, Scope 3 GHG emissions reporting remains voluntary until further notice.

Note: Scope 3 GHG emissions reporting remains voluntary until further notice.

• Scope 1: Direct emissions from sources you own or control

• Scope 2: Indirect emissions from the generation of purchased energy you consume

• Scope 3: All other indirect emissions (not included in Scope 2) that occur in your value chain (only for STI constituent listed companies initially)

You need to report information on how you manage climate-related risks and opportunities through:

• Governance;

• Strategy;

• Risk management; and

• Key metrics and targets used to measure progress.

The specific requirements are set out in the ISSB Standards (see note). ACRA is developing local sustainability disclosure standards based on the ISSB Standards.

Note: The ISSB Standards refer to IFRS S1 General Requirements for Disclosure of Sustainability-related Financial Information and IFRS S2 Climate-related Disclosures issued by the International Sustainability Standards Board.

ACRA developed the SR BOK to guide training providers in developing quality sustainability reporting programmes.

The SR BOK provides a comprehensive framework of essential knowledge areas. It covers key global standards such as:

• IFRS S1 General Requirements for Disclosure of Sustainability-related Financial Information

• IFRS S2 Climate-related Disclosures

• Greenhouse Gas Protocol

More than 50 key industry stakeholders validated the SR BOK. These include company preparers, assurance providers, professional bodies, and training providers.

The SR BOK aims to drive consistency in the depth of sustainability reporting training programmes across different providers.

ACRA collaborated with the Sustainable and Green Finance Institute (SGFIN) at the National University of Singapore to conduct a study on climate-related disclosures.

The study highlighted best practices in climate-related disclosures from local and overseas companies. It also recommended strategies on how companies can enhance their climate reporting, such as:

• Prioritising progress over perfection

• Making meaningful links to financial reporting

• Future-proofing strategy and business models

You can apply for the Sustainability Reporting Grant (SRG) to prepare for ISSB-based CRD before mandatory compliance begins.

The grant is offered by:

• Economic Development Board (EDB)

• Enterprise Singapore (EnterpriseSG)

Note: Application deadlines have been updated following ACRA and SGX RegCo’s announcement in August 2025 on extended timelines for climate reporting and assurance requirements.
