Monetary Authority of Singapore outlines SGX RegCo measures to improve listed company Scope 1 and 2 emissions disclosure reliability before FY2029 assurance mandate

In a parliamentary reply, the Monetary Authority of Singapore's chairman set out the measures used to support the accuracy and reliability of listed companies' Scope 1 and Scope 2 greenhouse gas emissions disclosures from FY2025, ahead of mandatory external limited assurance from FY2029. The framework relies on listed companies maintaining robust processes, data governance, internal controls and board oversight over disclosures, alongside SGX Regulation requirements aimed at improving measurement quality and transparency. Those requirements work in three ways. Listed companies must use the Greenhouse Gas Protocol for emissions measurement, disclose the approaches, inputs and assumptions used in their calculations, and internally review their sustainability reporting processes. The reply also noted that reporting capability has improved, with reporting rates rising between 2023 and 2025 from 50% to 87% for Scope 1 emissions and from 61% to 93% for Scope 2 emissions. Companies have also been supported by resources including the Singapore Emission Factors Registry, which contains more than 300 Singapore-specific emission factors consolidated mainly from government agencies. SGX Regulation will continue to monitor listed companies' disclosures and take follow-up action where breaches are found. External assurance on these disclosures is scheduled to be implemented in FY2029.
