The document discusses the need for more sustainable networking to address rising carbon emissions from information and communications technology (ICT). It notes that without changes, ICT carbon emissions will double by 2020 due to rising use of bandwidth-intensive applications like video. Alcatel-Lucent's GreenTouch research project aims to develop technologies that could increase network energy efficiency by 1,000 times within 5 years, addressing this looming crisis through a holistic approach rather than incremental steps. This involves ultra-low power access networks using efficient protocols and coding, as well as cloud computing with low-power thin clients to reduce energy use.
