For example, Dell is one of the few IT companies to go carbon neutral next year.
Dell Australia managing director, Joe Kremer, said the company will neutralize its carbon emissions and become carbon neutral by the end of 2008.
This makes Dell the first major computer manufacturer to announce its intention to balance its carbon emissions with activities that reduce carbon in the atmosphere.
Dell, the world's second-largest PC manufacturer, will also push its major suppliers to report and reduce their carbon emissions.
Kremer said customers demanding energy efficiency are pushing IT vendors away from the old price/performance metric to a new "performance per watt" metric.
