ACRA’s Climate-First Standards: Why S2 Is Mandatory and S1 Is Voluntary in Singapore

ACRA’s Climate-First Standards: Why S2 Is Mandatory and S1 Is Voluntary in Singapore

A Deliberately Narrower Mandate

ACRA’s draft Singapore Sustainability Disclosure Standards, published for public consultation on 27 July 2026 and open until 25 October 2026, are closely aligned with the ISSB framework but deliberately narrower in scope. The draft comprises two standards: SFRS S1 on general sustainability-related disclosures and SFRS S2 on climate-related disclosures. Only SFRS S2 is proposed to be mandatory, reflecting what ACRA calls Singapore’s “climate-first” approach.

That design choice is significant. Companies will not be required to report on the full spectrum of sustainability topics—biodiversity, labour practices, community relations—under the mandatory standard. The mandatory perimeter is climate. SFRS S1 remains voluntary, giving preparers a principles-based pathway to broader disclosure without turning it into an immediate compliance obligation.

Connectivity with Financial Statements

The draft standards propose that climate-related disclosures be published at the same time as financial statements, rather than allowing a later release. Singapore’s approach removes the ISSB’s relief that permits sustainability disclosures to follow financial statements. The rationale is connectivity: investors should be able to assess climate-related risks and opportunities alongside their financial effects, not in a separate reporting cycle.

This timing requirement has operational consequences. It pulls sustainability reporting into the financial close calendar, requiring coordination between finance, sustainability, and internal audit teams. For groups with complex consolidation processes, the simultaneous publication requirement may be one of the more demanding operational changes in the draft.

The Statement of Compliance and Accountability

The draft SFRS S2 requires an explicit and unreserved statement of compliance. ACRA has stated that this requirement holds entities accountable, provides users with a clear signal of compliance, and establishes a basis for assurance. The requirement is modelled on financial reporting practice, where a statement of compliance carries legal and professional consequences.

For directors, the statement of compliance raises governance questions. A qualified or inaccurate compliance statement could expose the board to reputational and legal risk. That dynamic is likely to drive greater board-level engagement with sustainability disclosures, particularly in companies where the sustainability report has historically been prepared with less oversight than the financial statements.

Targeted Reliefs for Scope 3 and Transition

The draft standards also adapt ISSB reliefs to Singapore’s context. Companies not required to disclose Scope 3 emissions receive an extended and ongoing relief beyond the first year of reporting, rather than the ISSB’s first-year-only transition relief. ACRA has also removed certain ISSB reliefs—such as the “timing of reporting” relief—that are considered unsuitable for Singapore’s regulatory approach.

The consultation period runs through 25 October 2026, after which ACRA will finalise the standards and prepare implementing legislation. The application dates are proposed as FY2028 for listed companies and FY2030 for large non-listed companies. For boards, the consultation window is the last structured opportunity to shape the final standard before it becomes binding.
