Microsoft

Microsoft's climate commitments are ambitious, aiming for carbon negativity by 2030 and removing all historical carbon emissions by 2050. The company is focused on reducing its operational footprint and influencing its value chain.

For the reporting year ending in 2025, Microsoft reported total global emissions of approximately 20.3 billion kg CO2e. This figure encompasses Scope 1, Scope 2, and Scope 3 emissions. Specifically, Scope 1 emissions were about 170.9 million kg CO2e, while Scope 2 emissions (market-based) accounted for approximately 2.7 billion kg CO2e. The vast majority of emissions, around 18.2 billion kg CO2e, fall under Scope 3, with significant contributions from purchased goods and services (approximately 5.1 billion kg CO2e) and capital goods (approximately 9.0 billion kg CO2e).

In the preceding year, 2024, Microsoft's total global emissions were approximately 16.2 billion kg CO2e. Scope 1 emissions were around 143.5 million kg CO2e, and Scope 2 (market-based) emissions were approximately 259.1 million kg CO2e. Scope 3 emissions were approximately 16.3 billion kg CO2e, with purchased goods and services accounting for about 5.6 billion kg CO2e and capital goods for approximately 6.3 billion kg CO2e.

Microsoft has set targets to reduce Scope 1 and 2 emissions to near zero by the middle of the current decade and aims to cut Scope 3 emissions by more than half by 2030, using a 2020 baseline. They are committed to achieving carbon negativity by 2030, meaning they will remove more carbon than they emit. Furthermore, by 2050, Microsoft aims to remove an amount of carbon equivalent to all its historical emissions since its founding. The company also pursues 100% renewable energy procurement for its electricity usage annually through to 2030.
