IBM strives to conserve resources across its operations. Two examples are water and materials conservation.
Internally, IBM's microelectronics manufacturing operations are our company's most water-intensive. In 2011, these operations represented more than 80 percent -- nearly 9,300 thousand cubic meters (TCMs) -- of the approximately 11,500 TCMs of water used at our manufacturing operations and laboratories worldwide.
Though our microelectronics operations are not located in areas of water scarcity, in 2000 we established a water conservation goal to achieve average annual water conservation savings equal to 2 percent of IBM's annual water use at microelectronics manufacturing operations, based on the water usage of the previous year and measured over a rolling five-year period. This voluntary environmental goal measures increases in annual water conservation resulting from new water reduction projects and improvements in water reuse and recycling at these locations.
In 2011, new water conservation initiatives in IBM's microelectronics manufacturing facilities achieved an annual 1.2 percent year-to-year increase in water conservation savings over 2010 usage.
Over the past 5 years, new water conservation initiatives at our microelectronics manufacturing facilities have achieved an average 2.6 percent savings versus the 2 percent goal.
Materials conservation and reuse
In addition to its waste recycling programs, IBM has a wide range of initiatives that conserve materials through reuse and recycling in the company's products and in its procurement of paper and wood-based packaging. Some examples:
