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

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.
