State Street Corp.

Regional hubs with large data centers serve many local sites.

State Street Corp. began its green initiatives in earnest in 2003 and has been rolling them out systematically ever since. The process began by benchmarking energy and water use, emissions of greenhouse gases and recycling. Those became baselines for goals going out several years, beginning with the Boston-based financial services firm's Massachusetts operations and expanding throughout North America and Europe. This year, its Environmental Management System (EMS), the framework for its green program, will be extended into Asia.

The impetus for State Street's sustainability efforts comes from employees, top management, customers and outside groups, says Richard Pearl, vice president for community affairs and head of the company's Office of Environmental Sustainability. And as EMS has increased in breadth, so has it grown in depth, he says. For example, two years ago, State Street committed to buying 20% of the energy for its Massachusetts facilities from renewable sources certified by Green-e, an independent consumer-protection program. Last year, it boosted that to 50%, Pearl says.

Madge M. Meyer, executive vice president and head of global infrastructure services, carries that broad view into IT. "I look end to end, from mainframes to end users, to identify opportunities for optimization," she says. At the user end of the spectrum, for example, the company has replaced 90% of its CRT monitors with energy-efficient flat-screen technology.

At the other end, State Street is consolidating the workload from many Unix-based servers onto big Linux-based mainframes. The resulting configuration will be more powerful, more energy efficient, and easier to provision and maintain.

"State Street has shown leadership in its environmental sustainability efforts," says Rakesh L. Kumar, an analyst at Gartner Inc. " The main thing is that consolidation -- which we have been preaching for so many years -- is still the best and simplest way to achieve energy savings."
