Climate reporting refers to the public disclosure by companies of information on their greenhouse gas (GHG) emissions, climate-related risks, opportunities, governance, strategy, and targets relating to sustainability. Listed companies in Singapore were required to report climate-related information on a "comply-or-explain" basis from the financial year 2022.

Reporting on Scope 3 emissions and external assurance requirements were to be made in later stages. The roadmap extended beyond listed entities, bringing large non-listed companies within the scope in later phases. Companies in Singapore are required to make the climate-related disclosure in line with the standards set by the International Sustainability Standards Boards (ISSB) i.e. IFRS S1 on general sustainability-related disclosures and IFRS S2 on climate-related disclosures.
