IT mitigation Videoconference 2-day trip to a meeting 1000km away, VC can save €1000 and 500kg of CO 2 per person Teleworking Every teleworker can save ~ 1 ton of CO 2 a year Dematerialisation & substitution e.g. E-books, e-banking etc

GN3-NA3.5
14
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
16
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 IT pilot

Conclusion
23
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
