MELBOURNE: Internet and other components of information communication and technology (ICT) industry annually produces over 830 million tonnes of carbon dioxide (CO2), the main greenhouse gas, and is expected to double by 2020, a new study has found.
Researchers from the Centre for Energy-Efficient Telecommunications and Bell Labs explain that the ICT industry, which delivers internet, video, voice and other cloud services , produces about 2% of global CO2 emissions — the same the aviation industry produces.
Researchers said their projections suggest that ICT sector's share in emissions is expected to double by 2020. They have also found new models of emissions and energy consumption that could help reduce their carbon footprint.
The study said 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.
Existing models are inaccurate, so they set out to develop new approaches that better account for variations in equipment.
