The Challenge

Climate change – some trends Climate Change 2007: Synthesis Report, IPCC

Global & Continental Temperature Change

The ICT Sector

Trends in ICT sector

Data centres 120 x 10 9 Kwh/year = ~2% of global CO 2 emission = emission from aviation industry

… we have to be SMART

Routers: a power law for power consumption

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

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 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

GHG audit

Preliminary results

HEAnet GHG emissions

GHG emission from schools network

HEAnet staff commute

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
