IBM, a US-headquartered company in the Computer and related services industry, is committed to reducing its carbon emissions.

In 2025, IBM's disclosed emissions included approximately 57,000,000 kg CO2e for Scope 1, 134,000,000 kg CO2e (market-based) for Scope 2, and significant Scope 3 emissions including purchased goods and services at approximately 6,290,000,000 kg CO2e, use of sold products at approximately 1,636,000,000 kg CO2e, capital goods at approximately 704,000,000 kg CO2e, employee commute at approximately 243,000,000 kg CO2e, and business travel at approximately 132,000,000 kg CO2e.

Looking back, in 2024, Scope 1 emissions were approximately 66,000,000 kg CO2e and Scope 2 (market-based) were approximately 199,000,000 kg CO2e. In 2023, Scope 1 emissions were around 71,000,000 kg CO2e and Scope 2 (market-based) were around 293,000,000 kg CO2e. For 2022, Scope 1 emissions were roughly 78,000,000 kg CO2e and Scope 2 (market-based) were roughly 352,000,000 kg CO2e. In 2021, Scope 1 emissions were approximately 78,000,000 kg CO2e and Scope 2 (market-based) were approximately 397,000,000 kg CO2e.

IBM has set ambitious climate commitments, including a goal to reach net-zero GHG emissions by 2030, with a target for residual emissions of 350,000 metric tonnes of CO2 equivalent or less. This commitment covers all scopes of emissions. As an interim target, IBM aims to reduce its Scope 1 and Scope 2 GHG emissions by 65% by 2025 against a 2010 base year, adjusted for acquisitions and divestitures. This 65% reduction target also applies to Scope 3 emissions associated with electricity consumption at co-location data centres from 2010 to 2025. IBM is also signed on to The Climate Pledge, committing to reach net-zero carbon by 2040.
