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

How to calculate and report?
Use the ISO 14064 standard
TNC201031 May – 3 June, 2010 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
TNC201031 May – 3 June, 2010 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
TNC201031 May – 3 June, 2010 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
• http://www.defra.gov.uk/environment/business/reporting/conversion-factors.htm• http://lct.jrc.ec.europa.eu/assessment/data
TNC201031 May – 3 June, 2010 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 guidelineshttp://www.defra.gov.uk/environment/business/reporting/ onversion-factors.htm
Business flights:The emissions are obtained by the ICAO Carbon emission calculator: http://www2.icao.int/en/carbonoffset/Pages/default.aspx

GHG abatement by GÉANT and other networks
TNC201031 May – 3 June, 2010 28
GN3/NA3/task5 next study
Use of networks to reduce GHG emissions
Current best practice:
•teleworking•video conferencing•electronic documents, e-mails (don’t print them!)•…
Estimated to save about 50 mio tonnes CO2e per year;at the expense of about 50.000 tonnes CO2e per year for networks and desktops/portables/notebooks;
An abatement factor of one thousand
To be investigated and confirmed!!
