Singapore Airlines

Singapore Airlines's climate commitments centre on achieving net-zero carbon emissions by 2050. This long-term target encompasses all scopes of emissions.

For the most recent reporting year available, 2025, Singapore Airlines reported a total of approximately 21.4 billion kg CO2e. This figure comprises Scope 1 emissions totalling about 17.1 billion kg CO2e, Scope 2 emissions of approximately 9.5 million kg CO2e, and Scope 3 emissions amounting to about 4.2 billion kg CO2e. Key contributors within Scope 3 for 2025 included fuel and energy-related activities at approximately 3.5 billion kg CO2e, and purchased goods and services at about 373.3 million kg CO2e.

In 2024, the airline recorded total emissions of approximately 18.8 billion kg CO2e. This included Scope 1 emissions of about 15.0 billion kg CO2e, Scope 2 emissions of approximately 10.1 million kg CO2e, and Scope 3 emissions totalling about 3.8 billion kg CO2e.

For the 2023 reporting year, Singapore Airlines's total emissions were approximately 15.8 billion kg CO2e. This consisted of Scope 1 emissions of about 12.7 billion kg CO2e, Scope 2 emissions of approximately 9.2 million kg CO2e, and Scope 3 emissions of about 3.0 billion kg CO2e.

Prior to 2023, Scope 3 emissions were not fully reported. In 2022, Scope 1 and 2 emissions combined were approximately 7.8 billion kg CO2e. Similarly, in 2021, Scope 1 and 2 emissions totalled about 4.0 billion kg CO2e. Between 2015 and 2020, total emissions (primarily Scope 1 and 2) ranged from approximately 13.8 billion kg CO2e in 2015 to 16.5 billion kg CO2e in 2020.

Singapore Airlines has explicitly stated its commitment to achieving net zero carbon emissions from its operations by 2050. This target aligns with a broader commitment to a 50% reduction in net aviation CO2 emissions by 2050, relative to 2005 levels. The airline's sustainability reports indicate progress and a comprehensive environmental policy to support these climate goals.
