In August 2025, the Accounting and Corporate Regulatory Authority (ACRA) and Singapore Exchange Regulation (SGX RegCo) extended the timelines for implementing climate reporting requirements, to support listed companies and large non-listed companies in developing reporting capabilities.

Under the revised timeline, issuers outside the Straits Times Index (STI) are still required to issue climate-related disclosures (CRD). However, they would now need to report only their Scope 1 and 2 greenhouse gas (GHG) emissions from financial year commencing on or after (FYC) 1 January 2025. Non-STI constituent issuers with a market capitalisation of $1 billion and above will be required to report CRD beyond Scope 1 and 2 GHG emissions based on the ISSB Standards from FYC 2028, with the exception of Scope 3 GHG emissions which will be voluntary until further notice. The remaining non-STI constituents will follow from FYC 2030. Notwithstanding this, they are expected to demonstrate progress towards incorporating the climate-related provisions in the ISSB Standards according to the relevant timeline.

The roadmap to navigate SGX's climate reporting timelines (the “Roadmap”) seeks to support non-STI constituent issuers in meeting the relevant timelines by FYC 2028, i.e. within the next three years. Non-STI constituents that have until FYC 2030 may adapt the Roadmap for their own use, although they are encouraged to adopt it earlier. As most issuers have already substantially adopted the TCFD recommendations, the Roadmap suggests how a non-STI constituent which has already adopted the TCFD recommendations may implement the climate-related requirements of the ISSB Standards.

To accomplish its objectives, the Roadmap outlines the key incremental disclosures required for issuers to build on their TCFD-aligned CRD to comply with the requirements in the ISSB Standards, as a guiding reference to support their transition to the ISSB requirements. In addition, it incorporates the insights provided in the aforementioned review of sustainability reports in 2024. It takes reference from existing materials that are publicly available, most notably those published by ISSB, SGX RegCo and the National University of Singapore Business School Centre for Governance and Sustainability.

The Roadmap was developed by SGX RegCo and ISCA, in support of the Singapore Green Plan 2030.
