Nowadays, the whole world of telecommunications and information communities is facing a more and more serious challenge (from 2G/3G/LTE to 5G), namely on one side the transmitted multimedia-rich data are exploding at an astonishing speed and on the other side the total energy consumption by the communication and networking devices and the relevant global CO2 emission are increasing terribly. It has been pointed out that “currently 3% of the world-wide energy is consumed by the ICT (Information & Communications Technology) infrastructure that causes about 2% of the world-wide CO2 emissions, which is comparable to the world-wide CO2 emissions by airplanes or one quarter of the world-wide CO2 emissions by cars”. According to the recent research report of Ericsson, energy costs account for as much as half of a mobile operator’s operating expenses. Therefore, telecommunications applications can have a direct, tangible impact on lowering greenhouse gas emissions, power consumption, and achieve efficient recycling of equipment waste. Moreover, to find radio networking solutions that can greatly improve energy-efficiency as well as resource-efficiency (Green Communications) is not only benefit for the global environment but also makes commercial sense for telecommunication operators supporting sustainable and profitable business. Within the framework of “5G Green Communications, a number of paradigm-shifting technical approachescan be expected, including but not limited to energy-efficient network architecture & protocols, energy-efficient wireless transmission techniques (e.g., reduced transmission power & reduced radiation), cross-layer optimization methods, and opportunistic spectrum sharing without causing harmful interference pollution (i.e. Green Spectrum).

 "Commission pushes ICT use for a greener Europe -  As part of its effort to combat climate change and drive economic recovery, the European Commission today called on Member States and industry to use information and communications technologies (ICT) to improve energy efficiency. These technologies are expected to reduce total carbon emissions in Europe by up to 15% by 2020. ICT can not only improve monitoring and management of energy use in factories, offices and in public spaces but above all help make people more aware of how they use energy. With smart metering in their homes, for example, consumers have been found to reduce their energy consumption by as much as 10%..."
