ICT BENEFITS SMART 2020

• Environmental- Cut global CO2 emissions in 2020
  by 15, with 946 billion of cost savings- Avoid
  c 5 tonnes of CO2 emissions through applications
  for every tonne created by production, use
  disposal of equipment
• Social- e.g. access overcoming disability

ENERGY CARBON FOOTPRINT

• Downloadable tool www.susteit.org.uk
• Default assumptions or your own data
• University of Sheffield- 19 of non-domestic
  electricity- 1 million bills in 2009- PCs
  higher than expected- Data centres/networks
  lower than expected

FHE - 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

KEY LIFE CYCLE QUESTIONS

• Can we ever get a complete picture?- HP 1.5
  million tonnes CO2 eq direct- 4.5 million tonnes
  from Tier 1 suppliers
• What balance of impacts across the life cycle?
  e.g. productionuse energy - Williams/UN
  University 41- EU Commission study 14
• How can we influence upstream impacts?

POTENTIAL MEASURES BY IT?
Short Term
Medium Term

• Specifying lower power equipment
• Automatic powerdown of networked devices
• Extending longevity
• Modifying data centre layout

• Increasing computer CPU utilisation
• Virtualisation
• Minimising storage
• Thin client in specialised applications

11
CROSS-FUNCTIONAL MEASURES
Short Term
Medium Term

• Awareness campaigns
• 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

12
CARDIFF UNIVERSITY

• Low power servers
• Chilled water cooling
• Efficient layout
• Efficient UPS
• 30 support overhead

13
LONG TERM CHANGES

• Less energy and material intensive desktops-
  cloud computing medium client- e-readers and
  total content
• Zero carbon data centres
• Pay as you go computing
• Intelligent campus- from computer to building
  maintenance?

14
REMOTE COMPUTING

• Direct outsourcing- Leeds Met using Google for
  student email and word processing (Google Apps)
• Collaborative outsourcing- London MAN for backup
• Managed service (e.g. accounting payroll)
• Common data centres- YHMAN Derby/Salford/Sheffiel
  d Hallam- economies of scale/scope- greater
  location flexibility- expert suppliers
