ISS's carbon emissions data for 2025 shows a total of approximately 2.28 billion kg CO2e. This figure comprises Scope 1 emissions of about 69.5 million kg CO2e, Scope 2 emissions of approximately 10.7 million kg CO2e (market-based), and substantial Scope 3 emissions amounting to roughly 2.2 billion kg CO2e.

For 2024, ISS reported total emissions of approximately 2.24 billion kg CO2e. Scope 1 emissions were around 70.4 million kg CO2e, Scope 2 emissions were approximately 9.5 million kg CO2e (market-based), and Scope 3 emissions totalled around 2.16 billion kg CO2e.

In 2023, ISS's total emissions were approximately 1.69 billion kg CO2e, with Scope 1 at about 66.2 million kg CO2e, Scope 2 at roughly 10.3 million kg CO2e (market-based), and Scope 3 at approximately 1.62 billion kg CO2e.

ISS has set ambitious climate targets. They aim to achieve net zero for Scope 1 and 2 emissions by 2030 and net zero for all scopes by 2040. Furthermore, their near-term targets, validated by the Science Based Targets initiative (SBTi), include reducing Scope 1 and 2 emissions by 46.5% and Scope 3 emissions by 27.5% by 2030, all relative to a 2019 baseline.
