connect communicate collaborate Introduction and Background: NRENs, their function and services
connect communicate collaborate ICT Carbon Footprint : Auditing template The aim of the template is to assist in the early stages of producing a greenhouse gas (GHG) report for a NREN or similar organization. The GHG emissions are divided into four classes, viz. office, data centre, backbone and transportation
connect communicate collaborate ICT Carbon footprint: Auditing template A two step method is used to calculate the GHG emissions in each class. The first step measures the energy consumption used by all activities of the class. In the second step the GHG emissions derived from these energy consumptions are calculated using public available emission factors. Unless you provide your own electricity, the electricity GHG emission values from the Joint Research Centre (JRC) of EU should be used in order to build a fair standard of comparison between different NRENs.
