ERCIM NEWS 79 October 2009 Keynote Towards Green ICT After years of token recognition, green Information and Communication Technology (ICT) is beginning to gain sig- nificant traction. In fact, the association of ‘greenness’ with technology has become so fashionable that companies are now trying to ‘out-green’ each other. The main catalyst for this change is the realization that energy consumption is Mazin Yousif, PhD growing at a staggering rate, far beyond that for which we CEO, Avirtec Corporation and chair of the ERCIM Advisory Committee. have prepared. The corollary for ICT is that as an industry, it is responsible for significant environmental impact. For example, it is not uncommon for newly constructed data cen- 3.
