根据所描述的定义（系统边界），对瑞典TeliaSonera运营的IP（互联网协议）核心网络进行了研究，并将其外推到瑞典的国家层面。自上而下和自下而上的数据收集方法已被用来量化网络设备和能源消耗。IP核心网络的耗电量约为所连接的移动的及固定接达网络的总耗电量的四分之一。瑞典IP核心网络的使用阶段结果是每GB（千字节）数据流量约0.08 kWh，对应于当应用瑞典电力混合时约19 g CO2 e/GB。如果使用全球平均电力组合，则产生的绿色房屋气体排放量将为约64 g CO2 e/GB。还提出了一种方法，其中使用的数据流量的量来分配IP核心网络上的不同用途。该方法的例子是在瑞典的3G移动的宽带数据业务。
The IP (Internet Protocol) core network operated by TeliaSonera in Sweden has been studied according to a described definition (system boundary) and extrapolated to a national level for Sweden. A top-down and a bottom-up data collection approach have been used to quantify network equipment and energy consumption. The electricity consumption of the IP core network was about one fourth of the total energy consumption of the connected mobile and fixed access networks. The use stage results for the Swedish IP core network is about 0.08 kWh per GB (Gigabyte) of data traffic corresponding to about 19 g CO2e/GB when applying a Swedish electricity mix. If instead a global average electricity mix is used, the resulting green house gas emission would be about 64 g CO2e/GB. A method is also proposed where the amount of data traffic is used to allocate the IP core network on different usage. The method is exemplified by the 3G mobile broadband data traffic in Sweden.
