Singapore mandates ISSB-aligned climate reporting for listed firms from 2025

Singapore will require listed companies to begin mandatory ISSB-aligned climate reporting in 2025, extending to large non-listed companies with at least 1 billion dollars revenue in 2027. For Indian companies operating in Singapore, the phased mandate signals tightening regional climate disclosure obligations aligned with global ISSB standards.

Singapore will implement mandatory climate-related reporting requirements aligned with the IFRS International Sustainability Standards Board standards, beginning as early as 2025. Announced by Second Minister for Finance Chee Hong Tat, with details from ACRA and SGX RegCo following Sustainability Reporting Advisory Committee recommendations, the requirements will be phased: listed companies from 2025, followed by large non-listed companies with at least 1 billion dollars in revenue and 500 million dollars in assets from 2027. Listed companies must report Scope 1 and 2 emissions first, Scope 3 in 2026, and obtain external limited assurance on Scope 1 and 2 two years after commencing.

Listed companies are affected first, required to report Scope 1 and 2 emissions from 2025 and Scope 3 from 2026. Large non-listed companies, defined as those with at least 1 billion dollars in revenue and 500 million dollars in assets, must begin reporting in 2027, with Scope 3 no earlier than 2029. Regulators ACRA and SGX RegCo oversee the requirements. Companies delivering climate disclosures stand to benefit from enhanced access to new customers, markets, and financing, and are better positioned to meet demand from customers, lenders, and investors for sustainability data.

Listed companies should prepare to report Scope 1 and 2 emissions from 2025, add Scope 3 in 2026, and arrange external limited assurance on Scope 1 and 2 emissions two years after commencing reporting. Large non-listed companies meeting the 1 billion dollars revenue and 500 million dollars asset thresholds should ready systems for 2027 reporting, with Scope 3 no earlier than 2029. Companies should align disclosures with ISSB standards and engage with ACRA and SGX RegCo guidance to access growing pools of sustainable capital and meet investor demand.
