Reducing the environmental impact of ICT:
Practical steps to cutting emissions.
Al Blake, Director, Technology Improvement Unit
Department of Environment, Water, Heritage and the Arts
“ICT accounts for approx 2% of global
CO2 emissions.That’s equivalent to aviation”
- Gartner
Since Kyoto (1997) Internet users have tripled.
ICT produces 2-3% of global emissions (excluding cooling)

Virtual server farm:
-32 Virtual servers/4 physical (50 tonne C02/pa)
-Improved redundancy/reduced provisioning time
Thin-client pilot:
-Significant C02 reduction
-Extended refresh period
-Reduced embodied energy
-Reduced transportation costs
DEWHA Virtualisation
Server Virtualisation - PIR
To date (August 2008) the project has achieved significant savings in power, carbon emission and projects costs:
• 99 mwHannual power saving, equivalent to 133 tonnes CO2 equivalent;
• $14,900 annual power cost saving; and• $116,000 saving compared to physical server
provisioning.
Thin-client Pilot• User profiles
– Office– Technical– Graphics
• Annual Savings (for 2400 desktops)– 475mWh power
• = 637 tonnes C02E = 3000 cars off the road– A$70,000 power costs.– Additional building air-conditioning savings
• Issues– USB Device Support– Streaming Media– Dual Monitor Support
Educate staff to reduce the amount of printing. Accept electronic copies of documents. Provide high -quality monitors for proof-reading online.
Print less
Set all printers to duplex (double-side) by default. Most modern printers can print multiple pages to a sheet. Use this format for proof-reading and discussion documents
Duplex Print and/or multi-page by default
Replace multiple small stand -alone devices with fewer, large networked units.
Consolidate printing
Reflecting the cost of printing back to the user or cost-centre significantly reduces print activity.
Charge-back for printing
Utilise low power, thin-client solutions to reduce the energy consumption per end user.
Virtualise desktop
Consolidate many physical servers into fewer virtual servers, ru nning on efficient hardware.
Virtualise servers
In many cases old unused computer equipment (especially servers) is left on 'just in case'. Consolidate and turn off old equipment.
Switch off old equipment
Mandate purchase of Energy-Star compliant computers and monitors. Phase out CRT monitors at refresh time. Require providers to demonstrate their environmental actions, including lifecycle management and require full identification of recycling and recovery operations to end-point disposal.
Adjust procurement guidelines
Schedule computers to shut-down when not required and automatically start-up for maintenance purposes. Educate staff to turn off equipmentthat can’t be automated
Auto shut-down Computers
Drop the use of active screen savers, which consume additional compute power (and energy). Turn power management functions on.
Disable screen savers
