  1. THE SUSTAINABLE DESKTOP – AN overview Professor Peter James www.susteit.org.uk

  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 Transport Manufacture Materials 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? Short Term Medium Term • 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

  8. CROSS-FUNCTIONAL MEASURES Short Term Medium Term • 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
