Singapore's sustainability reporting landscape is undergoing a significant transformation as regulators progressively align disclosure requirements with the International Sustainability Standards Board (ISSB) framework. Since FY2025, all SGX-listed companies are required to report Scope 1 and Scope 2 greenhouse gas (GHG) emissions, marking an important step towards greater transparency and comparability of climate-related information.  

Under the phased implementation roadmap, Straits Times Index (STI) constituent companies are leading the transition, with ISSB-aligned climate-related disclosures becoming mandatory from FY2025 and Scope 3 emissions reporting commencing from FY2026. Larger non-STI listed companies with a market capitalisation of S$1 billion or more will be required to adopt broader ISSB-based climate-related disclosures from FY2028, while other listed companies will follow from FY2030. For many organisations, this provides valuable preparation time, but the journey towards compliance often requires years of work to establish governance structures, climate risk management processes, reliable emissions data, and internal reporting controls.  

Forward-looking companies are therefore treating climate reporting as more than a compliance exercise. By strengthening GHG inventories, conducting climate risk assessments, engaging suppliers on emissions data, and integrating sustainability into strategic decision-making, organisations can improve resilience, meet stakeholder expectations, and position themselves competitively in increasingly sustainability-focused global markets.
