9 International Telecommunication Union 6. Networks and Systems influencing climate change (1/5) 9 International Telecommunication Union Although ICT networks and systems emit CO2, they also reduce direct CO2 output and have the additional capability of enabling other sectors of society to reduce their carbon footprint. With the introduction of fiber technology fixed networks gained additional speed and increased range while at the same time reducing power consumption. The energy efficiency improvement of fiber networks compared to copper networks is tremendous.
10 International Telecommunication Union 6. Networks and Systems influencing climate change (2/5) 10 International Telecommunication Union Data Center Data centers are being installed in line with the spread of broadband access. It is generally considered that data centers improve the efficiency of energy and resource consumption by consolidating distributed servers and sharing the use of facilities. However, concerns have been raised that the rising number of servers required to process the growing amount of information will increase the power consumption. To reduce CO2 emissions Key Technology Low-power server platform Green OS Energy-aware virtual platform Green-grid middleware Auto-system management Dynamic Smart Cooling,etc
11 International Telecommunication Union 6. Networks and Systems influencing climate change (3/5) 11 International Telecommunication Union Natural Cooling System The base station is cooled using natural cold air during the winter season which reduces the need for air conditioners. As a result, this energy efficient cooling system saved more than 15% of energy.
12 International Telecommunication Union 6. Networks and Systems influencing climate change (4/5) 12 International Telecommunication Union Tele-conferencing system Introduction of ICT systems will help reduce the movement of people using the traditional ways of travel. When the movement of people is reduced, energy consumption from traditional ways of travel and CO2 emissions can be reduced.. Video conference held between Tokyo and Yokohama, once a week (48 times / year), one hour each time, participated in by two people from each office

Networks and Systems influencing climate change (5/5) 13 International Telecommunication Union Home Networking The implementation of ICT-enabled energy saving applications minimizes the energy consumed by energy-hungry household appliances. Case: AIM architecture Advanced Metering Infrastructure (AMI) has following features: The two-way fixed network and associated systems for providing advanced metering data and energy management capability. Provides the capabilities to improve data tracking above and beyond Automated Meter Reading (AMR) with the goal of influencing energy usage. AMI can be incorporated into the sensor and communication infra of the intelligent micro-grid.
14 International Telecommunication Union 7. Use of ITU-T Standards to mitigate climate change (1/6) This section introduces some of the key ITU-T standards which can be applied toward mitigating climate change. It should be noted that the list of the ITU-T standards that address climate change is not limited by the technologies mentioned in this section. There are other ITU-T standards that can be applied.
15 International Telecommunication Union Next Generation Networks (NGNs) NGNs are seen by many as the new network architecture that will unify todays fixed, mobile and broadcast networks. NGN is expected to bring about greater energy efficiency than legacy networks. 7. Use of ITU-T Standards to mitigate climate change (2/6) In turn, by improving the energy efficiency of ICTs, NGNs can potentially make a significant contribution in the battle against global warming. NGNs providers and manufacturers should commit to reducing power consumption through migration to NGN Making use of Multiple Power Modes in NGNs related technology. Power consumption should be monitored in NGN devices to encourage their most efficient use.

18 International Telecommunication Union 7. Use of ITU-T Standards to mitigate climate change (5/6) Intelligent Transport System (ITS) ITS is one of the key technologies which can contribute to mitigating climate change. The ITU-T has published technical watch group reports on ITS, and in collaboration with other SDOs started its studies on standardization in SG 16. ITS is designed to achieve; Improvement of road safety and reduction of traffic accidents – Increase of traffic efficiency; Improvement of freight and public transportation efficiency; Reduction of CO2 emissions. Driver assist and management Main elements of Green-ITS
19 International Telecommunication Union Tag-based Identification Applications and Services 7. Use of ITU-T Standards to mitigate climate change (6/6) RFID is a representative Tag-based identification system which uses wireless communication technology to transmit the identifiers stored in an RFID tag to an RFID terminal. An RFID can hold multiple identifications for different purpose of wireless data communication, which enhances the efficiency of the process of the identification.
