The ICT Sector
Trends in ICT sector
Data centres
• 120 x 109 Kwh/year= ~2% of global CO2 emission= emission from aviation industry
… we have to be SMART
Routers: a power law for power consumption
IT mitigation
• Videoconference2-day trip to a meeting 1000km away, VC can save €1000 and 500kg of CO2 per person
• TeleworkingEvery teleworker can save ~ 1 ton of CO2 a year
• Dematerialisation & substitutione.g. E-books, e-banking etc
GN3-NA3.5
Structure of GN3• Joint research activities
- JRA1: future network- JRA2: multi-domain resources & services- JRA3: enabling communities
• Network activities- NA1: management- NA2: joint dissemination & outreach- NA3: status & trends- NA4: liaison & support
• Service activities- SA1: GÉANT network architecture design & planning, procuring, building & operating
- SA2: multi-domain service operation
- SA3: end-user services in a federated environment
- SA4: software governance

GN3-NA3.5: work programme
• Baseline audits...... of GÉANT and partner NRENs, using standards, such as ISO 14064
• Best current practice...... and practical policies
• Final results...... and recommendations
Throughout, liaison with other GN3 tasks, with NRENs and with projects such as Canarie’s Green

Conclusion
Further work
• Wasteful redundancy – dual PSU and equipment resilience ?
• Does equipment need to be powered on if it’s not in service or likely to be?
Some questions that need to be addressed, without impinging on the level of service
Investigating RE sources
