  1. Overview of Deliverable 4Direct and indirect impact (on energy) of ITU-T standards Editor’s Group of Deliverable 4 Sungchul Kang (KCC, Korea), Chairman Eunsook Kim “Eunah” (ETRI, Korea), Editor Takafumi Hashitani (Fujitsu, Japan), co-editor Franz Zichy (US State Department, USA), co-editor International Telecommunication Union

  2. Summary (SCOPE) This deliverable describes general checklists and guidelines, examples of networks and systems which influence climate change in the ICT field, and ITU-T standards that have a positive impact on mitigation of climate change. It is to allow ITU-T SGs to evaluate, for each Question, the possible future CO2E (carbon dioxide equivalent) reduction of technologies in terms of direct emissions from ICTs and possible savings in terms of Climate Change mitigation from the use of ICTs. It is noted that the list of ICT technologies and ITU-T standards introduced in this deliverable do not limit the possible and potential ICT technologies and ITU-T standards to impact climate change.

  6. 5. Checklist Checklists are useful for developing and promoting eco-friendly standards for ICT architecture, ICT devices, ICT providers, ICT systems, and disposal and recycling of ICT systems in an eco-friendly way. To lead • Limit the negative impacts • Enhance the positive impacts International Telecommunication Union International Telecommunication Union 6

  9. 6. Networks and Systems influencing climate change (1/5) 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. 6. Networks and Systems influencing climate change (2/5) 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 International Telecommunication Union International Telecommunication Union 10

  11. 6. Networks and Systems influencing climate change (3/5) 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. International Telecommunication Union International Telecommunication Union 11

  12. 6. Networks and Systems influencing climate change (4/5) 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 International Telecommunication Union International Telecommunication Union 12

  13. 6. Networks and Systems influencing climate change (5/5) Home Networking The implementation of ICT-enabled energy saving applications minimizes the energy consumed by energy-hungry household appliances. • 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. 7. Use of ITU-T Standardsto 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. International Telecommunication Union

  15. 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. 7. Use of ITU-T Standardsto mitigate climate change (2/6) Next Generation Networks (NGNs) NGNs are seen by many as the new network architecture that will unify today’s fixed, mobile and broadcast networks. NGN is expected to bring about greater energy efficiency than legacy networks. In turn, by improving the energy efficiency of ICTs, NGNs can potentially make a significant contributionin the battle against global warming. International Telecommunication Union

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 7. Use of ITU-T Standardsto 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.

  19. 7. Use of ITU-T Standardsto mitigate climate change (6/6) Tag-based Identification Applications and Services 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.
