1 GÈANT3 Carbon Footprint 2009 Jørgen Moth, UNI-C.

2 Carbon footprint? the carbon footprint measures the total greenhouse gas (GHG) emissions caused directly and indirectly by a person, organization, event or product 2

3 DANTE, City House, Hills Road, Cambridge, UK 3

4 GÉANT Network 4

5 Question: GHG/Year due to GÉANT/DANTE? GÉANT Climate impact 200 kg CO 2 e/year? 200 tonnes CO 2 e/year? 2000 tonnes CO 2 e/year? tonnes CO 2 e/year? tonnes CO 2 e/year? 2 mio tonnes CO 2 e/year? (Total Europe about 5000 mio tonnes CO2e/year) 5

6 Answered by GN3/NA5/task tonnes CO 2 e in 2009 Corresponding to 200 Danish Citizens 0,00004 % of European total 6

7 Who are GN3/NA3/task5? GN3: Multi-Gigabit European Research and Education Network and Associated Services NA3: Networking Activity 3 Status and trends Task 5: Study of Environmental impact Partners: HEAnet (Ireland - Mike Norris) NIIF (Hungary - Tamas Maray) PSNC (Poland - Rafal Sowinsky, Robert Pekal, Artur Juszczyk) NORDUnet (Denmark, Finland, Iceland, Norway, Sweden Lars Fischer, Jørgen Moth) 7

8 GN3 Budget (Mio EURO) 0,8 181 NA3/task5 GN3 8

9 How to calculate and report? Use the ISO standard 9

10 Which GHG emissions? Scope 1: own emissions standby generators, own cars, own heating,.. Scope 2: indirect emissions imported energy, heating and electricity Scope 3: other indirect emissions e.g. transportation Stemming from the operation of the GÉANT network by DANTE 10

11 GÉANT/DANTE Baseline audit (GHG Report) Scope 1 emissions Nothing (no own cars; fuel to stand-by generators ignored) Scope 2 emissions Office light, heating & cooling, equipment Datacentres routers, switches, services Backbone - ILAs Scope 3 emissions Transport business, commuting 11

12 Calculation of Scope 2 GHG emissions A two step procedure is used: 1)Heating and electricity consumption data provided by DANTE (Kudos to Guy Roberts!) 2)Consumption values multiplied by GHG conversion factors retrieved from UK and EU data bases

13 Calculation of Scope 3 GHG emissions Business travels and commuting by car, bus, taxi or train: The distances covered are multiplied by the corresponding GHG conversion factors from the UK DEFRA guidelines onversion-factors.htm Business flights: The emissions are obtained by the ICAO Carbon emission calculator: 13

27 GHG abatement by GÉANT and other networks

28 GN3/NA3/task5 next study Use of networks to reduce GHG emissions Current best practice: teleworking video conferencing electronic documents, s (don t print them!) Estimated to save about 50 mio tonnes CO 2 e per year; at the expense of about tonnes CO 2 e per year for networks and desktops/portables/notebooks; An abatement factor of one thousand To be investigated and confirmed!! 28
