Singapore Extends Climate Reporting Timelines for Smaller Companies

Singapore’s regulators eased climate reporting requirements for smaller firms by pushing back most ISSB-based disclosures. While all listed companies still had to begin reporting Scope 1 and 2 greenhouse gas (GHG) emissions from FY2025, deadlines for broader disclosures were extended to give businesses more time to prepare.

The revised framework introduced a three-tier approach: Straits Times Index (STI) companies, non-STI companies with market capitalization above $1 billion, and those below $1 billion. STI companies stayed on the original schedule, with Scope 3 reporting starting in FY2026. Larger non-STI firms were given until FY2028 to begin ISSB-based disclosures, while smaller non-STI companies had until FY2030. Scope 3 remained voluntary for non-STI firms.

Large non-listed companies also saw their timelines pushed back. Scope 1 and 2 reporting shifted from FY2027 to FY2030, with external assurance requirements deferred to FY2032. Regulators explained that the move was aimed at balancing capability-building with compliance, especially since only a small fraction of smaller firms felt ready for the earlier deadlines.

By staggering the requirements, Singapore sought to maintain momentum on its 2050 net-zero target while giving smaller businesses the space to strengthen systems, improve data quality, and build confidence in sustainability reporting.

Singapore's three-tier ISSB adoption approach - STI companies on original schedule (Scope 3 from FY2026), larger non-STI firms to FY2028, smaller non-STI to FY2030 - reflects pragmatic recognition that capability-build requires time proportionate to firm scale. Large non-listed firms' Scope 1/2 shift from FY2027 to FY2030 further extends preparation runway.

The capability-building framing rather than compliance-only framing is analytically important. Sustainability reporting delivers value only when data is high-quality and integrated with strategic decision-making; premature mandatory reporting without capability build produces poor-quality data that undermines investor confidence and strategic utility.
