2. A LARGE ICT FOOTPRINT 2% of global CO2 emissions ICT in UK HE - 760,000 PCs - 215,000 servers - 147,000 networked printers - 512,000 Mwh of electricity - 275,000 tonnes of CO2 - over £60 million in 2009

3. 325,000 Coal-Powered Computers

4. A LARGE FOOTPRINT Materials Manufacture Transport Use Disposal

5. DESKTOP LIFE CYCLE IMPACTS

6. WHY IT MATTERS TO HE Corporate responsibility Cost - 50 to 100% rise in electricity prices? Carbon - growing regulation - Carbon Reduction Commitment Curriculum and research

7. POTENTIAL MEASURE BY IT? Specifying lower power equipment Automatic powerdown of networked devices Powering down non- networked computers Extending longevity Modifying data centre layout Increasing computer CPU utilisation Virtualisation Minimising storage Thin client in specialised applications Short TermMedium Term

8. CROSS-FUNCTIONAL MEASURES Powerdown of non networked devices Upgrading data centre power supply arrangements Increasing use of videoconferencing Maximum use of thin client where effective Free cooling of data centres Effective document and print management Short TermMedium Term
