Abstract


The information and communication technology (ICT) sector is changing:
Data volumes and ICT usage is growing exponentially, ICT infrastructure is
shared by many services instead of used only by voice, the volume of end
user (customer) devices is increasing but at the same time the telecom
operator’s internal electricity consumption remains almost constant. This
paper elaborate on identified trends during the period 1990 to 2010 using
data from several LCA studies over time to conclude what implications can
be drawn on the estimated environmental impact.
