  • IBM will achieve net zero greenhouse gas (GHG) emissions by 2030 to further its decades-long work to address the global climate crisis. To accomplish its net zero goal, IBM will do the following:
    • Continue to drive energy conservation throughout its business. This effort includes implementing at least 3,000 new conservation projects to avoid the consumption of 275,000 megawatt-hours (MWh) of energy from 2021 to 2025. The company will also improve its average data center cooling efficiency 20% by 2025 versus a 2019 base year.
    • Procure 75% of the electricity it consumes worldwide from renewable sources by 2025 and 90% by 2030. This includes renewable electricity that is part of the grid mix IBM receives from utilities, in addition to renewable electricity it generates on-site or contracts to purchase beyond what is in the grid mix.
    • Reduce its GHG emissions 65% by 2025 against base year 2010, adjusted for acquisitions and divestitures. This is the company’s fifth GHG goal since its first goal in 2000. IBM’s planned reductions exceed the rate recommended by the UN Intergovernmental Panel on Climate Change to limit Earth’s warming to 1.5 degrees Celsius above preindustrial levels.
    • Use feasible technologies, such as carbon capture (in or by 2030), to remove emissions in an amount that equals or exceeds the level of IBM’s residual emissions.
  • Since 1990, IBM has conserved 9.8 million MWh of energy, avoided 4.6 million metric tons of carbon dioxide (CO2) emissions, and saved $661 million through its energy conservation efforts.
  • In 2020, the company surpassed its fourth-generation goal five years early when it reduced its CO2 emissions 56.6% against base year 2005, adjusted for acquisitions and divestitures. IBM set its first goal regarding CO2 emissions in 2000 and has been voluntarily disclosing its CO2 emissions since 1994. 
  • In 2020, 59.3% of the electricity consumed across IBM’s global operations came from renewable sources, surpassing its second-generation goal of 55% by 2025 five years early. IBM made its first renewable electricity purchase in 2000. 



  • Server and storage products enable clients to execute more IT work with higher equipment utilization rates in a smaller equipment footprint.
  • IT solutions and services based on data analytics and cognitive and artificial intelligence (AI) technologies provide clients with new insights into their operations.
  • IBM Research is helping accelerate the discovery of new materials for carbon removal, leveraging its expertise in materials science and advanced computing with its Future of Climate initiative.
