Lowering Canberra's Carbon emissions using ICT

At the ACS Canberra Branch 2009 Conference I will be talking about "Green IT Strategies: Lowering Cost and Carbon Emissions with ICT". This is in the Tomorrow's World stream. As this is in Canberra, I will be focussing on what the Australian Public Service and the companies supporting it, can do directly to lower carbon emmissions. Contrary to popular opinion, this is not about switching off your computer monitor or spending money on expensive new equipment.
