Information and Communication Technologies have the potential of a key enabler for cross-industry Low Carbon strategies, in the economy and in the society as whole.Initiatives of virtuous "green"employment of ICT across several sectors are being worked on.In the front line are the "smart grids" initiative(s), attacking the problem at its very roots-the energy production and distribution systems used for the economies, and societies.Smart metering is another group of such initiatives not only for electricity but also for utilities networks in general (water, gas).Another sector are expected to benefit from "smart ICT solutions is the transport area-the so called Intelligent transport Systems, including automotive, railways, aviation.Or measures that contribute to alleviate the transport burden through its substitution through by communications.Other areas are the "smart cities", "e-Health", smart manufacturing/including wireless factories, ambient assisted living, sensors, robots.It is argued that the increased use of ICT might overall impact emissions and energy consumption.The parallel work being developed in the ICT sector, concerning emissions and energy consumption, in implementation, d R&D and standardization, shows the potential for a sharp reduction of emissions and energy consumption.LCA standards are used to guide us.Universal chargers for electronic equipment (personal computers, smartphones, etc), standby low consumption strategies for systems and equipments, optimized overall network architectures, breakthroughs wit cloud computing-a revolution is under way.
