IBM, a US-based company operating in computer and related services, has made significant commitments to reducing its carbon emissions.

For the reporting year 2025, IBM reported total Scope 1 emissions of approximately 57 million kg CO2e. Scope 2 emissions, using the market-based method, were approximately 134 million kg CO2e. Scope 3 emissions, including categories such as capital goods, business travel, employee commute, use of sold products, and purchased goods and services, collectively amounted to approximately 7.7 billion kg CO2e.

IBM has a clear target to reach net-zero greenhouse gas (GHG) emissions by 2030. This commitment includes aiming for residual emissions of 350,000 metric tons of CO2 equivalent or less by the same year, utilising feasible technologies for emission removal.

Furthermore, IBM previously set a target to reduce its GHG emissions by 65% by 2025, against a base year of 2010, with adjustments for acquisitions and divestitures. This target applied to Scope 1 and Scope 2 emissions.

In earlier years, for instance in 2020, IBM reported Scope 1 emissions of approximately 73 million kg CO2e and Scope 2 market-based emissions of approximately 262 million kg CO2e. Scope 3 emissions in 2020, covering categories like business travel, employee commute, use of sold products, upstream leased assets, and purchased goods and services, totalled approximately 564 million kg CO2e.

IBM has also committed to the Climate Pledge, aiming for net-zero carbon emissions by 2040.
