9. connect communicate collaborate GHG Audit, 2008/09: total, 1765 tons of CO 2 equivalent

10. connect communicate collaborate Actions taken Office power, change to ‘greener’ supply Staff environmental awareness day Revise policy on school routers Review commercial data centre practice Maintain ‘green’ criteria in procurements Increase usage of VC to replace travel Agree to carry out audit of asset database Poll staff for ideas

12. connect communicate collaborate Comparison of the two audits

13. connect communicate collaborate Normalise and compare

14. connect communicate collaborate 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 ?

15. connect communicate collaborate 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.
