Washington: Internet,
video and other cloud services, which comprise information
communications and technology (ICT) industry, spews out more than
830 million tonnes of carbon dioxide annually, researchers found.
Carbon dioxide is also the main greenhouse gas; and the emissions
from the information and communications industry alone accounts
for about two percent of global CO2 emissions, the same proportion
as the emissions from the aviation industry.
Projections suggest that the ICT sector's share is expected to
double by 2020, according to researchers from the Centre for
Energy-Efficient Telecommunications (CEET) and Bell Labs.
Researchers note that controlling those emissions requires more
accurate but still feasible models, which take into account the
data traffic, energy use and CO2 production in networks and other
elements of the ICT industry, the journal Environmental Science &
Technology reports.
Existing assessment models are inaccurate, so they set out to
develop new approaches that better account for variations in
equipment and other factors in the ICT industry, according to a
CEET and Bell Labs statement.
Amid growing concern over the surprisingly large amount of
greenhouse gas produced by the Internet and other telecom
activities, researchers are reporting new models of emissions and
energy consumption that could help reduce their carbon footprint.
The researchers suggest, based on their models, that more
efficient power usage of facilities, more efficient use of
energy-efficient equipment and renewable energy sources are three
keys to reducing ICT emissions of CO2.
CEET is a partnership between Alcatel-Lucent, the University of
Melbourne and the Victorian State Government.
