2. What is GreenTouch? GreenTouch is consortium aiming at reducing the energy consumption in the telecommunication network by a factor of 1000 by 2015. It is a relative and not an absolute diminution (definition given later). Mission By 2015, our goal is to deliver the architecture, specifications and roadmap — and demonstrate key components — needed to reduce energy consumption per user by a factor of 1000 from current levels. It was initiated by Bell-labs, research arm of Alcatel-Lucent It was launched on January 11 th 2010 There are 18 founding members: manufacturers (Alcatel-Lucent, Huawei, Samsung, Freescale), operators (Swisscom, Portugal telecom, Telefonica, Orange, ATT), research institutes (IMEC, CEA- LETI, INRIA) and universities (Melbourne, Stanford, MIT) New members have joined: among others, NTT, Vodafone, China Mobile, Korea Telecom, many universities and very recently Broadcom and Fujitsu. At present, there are 35 members. 06.05.2011 2 For internal use, Claude Monney, SIS-ICC-ENV
