Debate around the greening of IT has so far concentrated on how IT departments and suppliers can get their own houses in order, but at this week's Gartner ITxpo event in Cannes the role that IT departments could play in helping to cut business carbon emissions took centre stage. And Tesco illustrated that helping to green the business was the bigger prize when it revealed that IT accounted for just 3% of its carbon footprint.

Other highlights of the event included SAP's CEO talking candidly about the competition posed by software-as-a-service.

"There's an old joke about a shop assistant who tells a customer "You must be the twentieth person I've told today - we don't stock it because there's no demand!". Until there are simple procurement rules in place to ensure that government systems that use a web browser as a client work with all popular browsers, and that all documents should be in open standard formats, MS will remain the default choice. Inertia in procurement won't put OSS on the shelves or in government use."
