Dell, the Round Rock, Texas computer company, announced today that it is moving up its scheduled date for the company to be carbon neutral, which means that Dell will offset all greenhouse gas-producing activities with other activities that help reduce greenhouse gases. Dell has been a leader in the PC industry for environmental initiatives, with an aggressive and free “take-back” policy for its computers and other equipment.

“In terms of producer takeback, they have the best policy of any global electronics company, period,” Robin Schneider, of the Texas Campaign for the Environment, told CNN last March. “They went from being a laggard to being a leader.”
