Company Ahead of Schedule to Meet Carbon-Neutrality Commitment

Dell is now powering 100 percent of its 2.1 million square-foot global headquarters campus, home to more than 10,000 employees, with 100 percent green power, the latest step in meeting the company's 2008 carbon neutral commitment.

"It's time for our industry to take a lead role in creating a clean energy future," said Paul Bell, president, Dell Americas. "Today, we are challenging every technology company to work with their suppliers and partners in integrating green power and energy-efficient strategies into their operations."

"Powering an entire campus with green power, in partnership with these two leading companies, is an important step in becoming the greenest technology company on the planet and the right thing to do for our shared earth," said Mr. Bell. "At the same time we're using green technology to drive operating expense down."

Dell is using all of the power generated from Waste Management's Austin Community Landfill gas-to-energy plant, meeting 40 percent of Dell headquarters' campus power needs. The remaining 60 percent comes from existing wind farms and is provided by TXU Energy.

Dell also announced today it is increasing green power use for its Austin Parmer Campus, provided by Austin Energy, from eight to 17 percent. The company is a leading participant in Austin Energy's GreenChoice® power program. Dell also is powering its Twin Falls, Idaho, facility with 100 percent green power, 97 percent of which is wind power and three percent solar.

In September 2007, Dell announced it would make company owned and leased facilities "carbon neutral" in 2008 through a strategy of improving energy-efficiency in its operations and maximizing the purchase of renewable power. This commitment is part of the company's climate strategy which also seeks to minimize carbon impact of supplier operations and customer product use.

Operational initiatives to increase efficiency and reduce electricity use already implemented on Dell's central Texas campuses are expected to save the company nearly $2 million annually in operating costs and cutting CO2 equivalent emissions by nearly 12,000 tons per year. The purchase of green power gives Dell price certainty on its operational costs for power, and the company expects it may see cost benefits to using green power in the future.

Dell's green technology solutions include the OptiPlex 755 and Inspiron 531 desktops, Latitude D630 laptop, PowerEdge M-Series blades and PowerEdge Energy Smart servers. The company's desktop systems alone have helped customers save more than $2.2 billion and avoid approximately 22.4 million tons of CO2.

"We're very pleased that our Austin Community Landfill's gas to energy project will play a key role in Dell's commitment to using renewable energy. This project is part of our company's environmental initiative to increase the production of waste based energy. Today, we create enough energy for the equivalent of 1 million homes each year and by 2020 we expect to double that output, producing enough energy for the equivalent of more than 2 million homes," said David Steiner, chief executive officer of Waste Management, Inc.

"This is yet another example of TXU Energy's commitment to offering renewable power choices that are good for business and the environment," said Jim Burke, chief executive officer for TXU Energy. "TXU Energy is dedicated to improving our use of renewable power and encouraging greater energy efficiency, both of which help preserve our environment."

"For Dell to partner with Waste Management and TXU Energy to source renewable energy on this scale is great news," said Steve Howard, CEO of The Climate Group. "Greening the company's Texas operations not only underpins Dell's bold carbon neutral commitment but helps drive clean energy investment and tackles climate change."
