Conclusions

Renewable mix of electricity has a real effect

Use of videoconferencing reduces travel

(So do the recession and budget cuts)

Schools 100Mbps project has significant effect

Client resilience project also increases Carbon footprint

Major increase in storage and server business has effect

Scope increasing as clients outsource more to HEAnet

Efficiencies can’t offset the absolute upward trend

Need for more renewable energy sources

Other ?


By Sector

Core networks and data centres/PoPs are the largest factors in network carbon footprints. So this is where the biggest reductions need to be made.
