Singtel, headquartered in Singapore, reported total carbon emissions of approximately 2.52 billion kg CO2e in 2026. This included about 18.84 million kg CO2e from Scope 1 emissions, approximately 296.89 million kg CO2e from market-based Scope 2 emissions, and around 2.20 billion kg CO2e from Scope 3 emissions.

In 2025, total emissions were approximately 2.85 billion kg CO2e, with Scope 1 emissions at about 13.23 million kg CO2e, market-based Scope 2 emissions at approximately 342.54 million kg CO2e, and Scope 3 emissions around 2.49 billion kg CO2e.

Looking back to 2022, Singtel's total emissions were approximately 8.64 billion kg CO2e, comprising about 6.32 million kg CO2e in Scope 1 emissions, approximately 488.62 million kg CO2e in market-based Scope 2 emissions, and around 8.15 billion kg CO2e in Scope 3 emissions.

Singtel has set ambitious climate commitments. The company is committed to achieving net-zero greenhouse gas emissions across its value chain by FY2045. As near-term targets, Singtel Group aims to reduce absolute Scope 1 and 2 GHG emissions by 55% by FY2030 from a FY2023 base year. Concurrently, they commit to reducing absolute Scope 3 GHG emissions from purchased goods and services, capital goods, use of sold products, downstream leased assets, and investments by 40% within the same timeframe. Long-term targets include a 90% reduction in absolute Scope 1, 2, and 3 GHG emissions by FY2045 from a FY2023 base year. These targets are validated by the Science Based Targets initiative (SBTi) and are consistent with reductions required to keep global warming to 1.5°C.

Additionally, Optus, a subsidiary, committed to reducing Scope 1 and Scope 2 GHG emissions in Australia by 25% by 2025, against a 2015 baseline. Singtel is also working towards having 100% of its electricity requirements backed by renewable energy sources by the end of 2025.
