What does it take to become one of the greenest technology companies on the planet? In part, support from thousands of customers who care. Since 2007, Dell customers have donated more than $2.3 million to the company’s Plant a Tree program, which benefits Go Zero. Small change can have big results; it’s only $2 to offset the CO2 emissions of your notebook. Already, Dell and its customers have helped Go Zero plant 190,000 seedlings from Texas to Louisiana.
