Session Description

Sustainability and environmental challenges require innovation in the different regions of the world. ICT infrastructures have been identified as a key element in global strategies for sustainability across society. The ICT sector is estimated to account for around 2% of the global GHG footprint (equivalent level to airline industry) but has the potential to reduce global GHG emissions by 16.5% by 2020, amounting to $1.9 trillion in gross energy and fuel savings and a reduction of 9.1 GtCO2e of GHG. This is seven times the size of the ICT sector own GHG footprint by 2020. This benefit will happen by the further design and development of smart users technologies, smart grids, smart buildings, smart transportation… to monitor and control energy use and to globally contribute to smarter cities, communities and society.

The benefits of ICT networks depend on scalable and ubiquitous ICT network connectivity. Traffic will continue to dramatically grow, in particular the mobile traffic, with a diversity of network services, applications and energy hungry capabilities continuing to expand. Energy use of infrastructure elements (transmission, e.g. base stations, and storage, e.g. data centers) is becoming a significant fraction of the service and communications providers OPEX. Major new technological innovations are needed to keep pace with these changes and continue network scaling into the future.

This session is building on recent sessions organized worldwide on sustainability and green ICT, taking here a different and disruptive approach “Green ICT: What would be the cost of doing nothing?” and asking the following questions:
1) What are the energy consumption and related costs of ICT infrastructures?
2) What are the risks of the “doing nothing” approach and what would be the ending point in 2020 and 2030 for a business as usual situation?
3) What are the top energy efficiency challenges for ICT infrastructures today and tomorrow?
4) What is the scale of effort and related costs to enhance ICT infrastructures energy efficiency?
5) What could be the potential infrastructure migration path from now to 2020-2030?

The targeted audience is:
1) Researchers and developers from industry and academics engaged in research on Green ICT, energy efficiency, ICT infrastructures architectures, smart grids programmes and projects.
2) Innovation leaders and entrepreneurs interested to know more about the developments of Green ICT programmes and projects and participate to the discussion on the potential innovation and business opportunities ahead.


1) Session introduction and framing (10 mns) – Didier Bourse (Alcatel-Lucent).
2) Green ICT presentations (30 mns).
- Philippe Richard (Alcatel-Lucent).
- Alice Valvodova (GeSI Executive Director).
3) Panel discussion and interaction with audience (70 mns) – Moderated by undefinedMarco Ajmone Marsan (Politecnico di Torino).
The panel will address the key perspective “Green ICT: What would be the cost of doing nothing?” and focus on the five questions listed in the session description.
The panellists will include:
