Singtel's Carbon Emissions and Climate Commitments

Singtel, a Post and telecommunication services company headquartered in Singapore, reported total carbon emissions of approximately 2.52 billion kg CO2e in 2026. This includes about 18.84 million kg CO2e from Scope 1, approximately 296.89 million kg CO2e from market-based Scope 2, and around 2.20 billion kg CO2e from Scope 3 emissions. In the previous year, 2025, total emissions were higher at approximately 2.85 billion kg CO2e, with Scope 1 at about 13.23 million kg CO2e, market-based Scope 2 at approximately 342.54 million kg CO2e, and Scope 3 at about 2.49 billion kg CO2e.

Climate Commitments and Targets: Singtel has established robust climate commitments, validated by the Science Based Targets initiative (SBTi), aiming for an overall net-zero GHG emissions across its value chain by FY2045.

Near-Term Targets (FY2030):

• Reduce absolute Scope 1 and 2 GHG emissions by 55% from a FY2023 base year.
• Reduce 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, using a FY2023 base year.

Long-Term Targets (FY2045):

• Achieve a 90% reduction in absolute Scope 1, 2, and 3 GHG emissions from a FY2023 base year.

Previously, Singtel committed to a 40% reduction in Scope 1, 2, and 3 GHG emissions by 2030 from a 2015 base year, classified as consistent with a "Well-below 2°C" pathway by SBTi.

Furthermore, Singtel aims to have 100% of its electricity requirements backed by renewable energy sources by the end of 2025. Optus, a subsidiary, has committed to reducing its Scope 1 and 2 GHG emissions in Australia by 25% by 2025, compared to a 2015 baseline.
