Energy and climate

IBM's first formal environmental and energy corporate policies date back to 1971 and 1974 respectively, and corporate-wide programs supporting them have been embedded within the company's global environmental management system since that time. IBM has been a leader in addressing climate change through our energy conservation and climate protection programs for decades.

From 1990 through 2021, IBM conserved 9.9 million megawatt-hours of energy — equivalent to more than double IBM's current annual energy consumption — saving $670 million and avoiding 4.6 million metric tons of carbon dioxide (CO2) emissions.

In February 2021, IBM announced its third successive goal for the use of renewable electricity, fifth successive goal to reduce greenhouse gas emissions, and set a new goal to achieve net-zero greenhouse gas emissions. Specifically:

Our energy and emissions goals and reporting cover all activities taking place in IBM-owned or leased facilities. These facilities include IBM data centers located in facilities managed by third parties where IBM does not procure the energy or control the operations of the buildings — also known as co-location data centers.
