The Uptime Institute yesterday announced the list of 100 companies that it selected as winners of its Global Green 100 list for businesses that have made significant steps toward greening their data centers.

Companies from the Fortune 500 and InformationWeek 500 lists were chosen based on the extent of their commitments to boosting energy efficiency and lowering the carbon footprint in their IT operations. The businesses selected had all demonstrated board-level green IT policies and ongoing commitment from a governance standpoint.

"Only 1 to 2 percent of total energy consumed in a data center produces useful computing. In an era of increasing energy scarcity and escalating costs, corporations cannot afford to ignore these losses," said Kenneth G. Brill, Executive Director of the Uptime Institute. "The companies included in the Global Green 100 have showed an exemplary commitment to improving their data center operations, not only reducing their carbon footprints, but also realizing significant financial savings."

Among the winners of the Global Green 100 are IT industry titans like Apple, Dell, Microsoft and Oracle, as well as companies that are not traditionally known as IT heavyweights, but who nonetheless have large-scale tech needs. Accenture, Cummins, Delta Air Lines, MetLife, Black & Decker and Waste Management are among those companies that are making the most of their tech departments.

The Uptime Institute will officially recognize the Global Green 100 at their Uptime Symposium in New York City on April 13; the theme of that conference is Lean, Clean and Green, and will focus on ways to get the most bang and the least carbon from your IT platform.

The full list of the Global Green 100 is currently online only in a press release from the Uptime Institute. For more information on the Uptime Symposium, visit UptimeInstitute.org.
