1. May 2010 1 ITU-T Workshop ICTs: Building the Green City of the Future Arthur Levin Chief, ITU-TSB ICTs as a Tool to Combat Climate Change United Nations Pavilion EXPO-2010, 14 May 2010 Shanghai, China

2. May 2010 2 ICTs and Climate Change Methodology to describe and estimate present and future user [energy] consumption of ICTs over their entire life cycle Smarter standards for greener systems Participation in COP UN Secretary-General, Ban Ki-moon: "ITU is one of the very important stakeholders in the area of climate change." Participants in Focus Group ICT and Climate Change

3. May 2010 3 Importance further identified at top level WTSA-08, Resolution 73, resolves that CC is a high priority in ITU WTPF (April 2009), Opinion 3, instructs promotion of Resolution 73, etc. GSC-14 (July 2009), Resolution, encourages related collaboration, etc. ITU Council (October 2009), Resolution 1307, unanimously decided its importance and active participation in UNFCCC including COP-15 in Copenhagen

5. May 2010 5 Why It Matters Impact of CC is costly for many countries even though they are not a major source of emissions E.g. total GHG emissions of Pacific Island countries is around 0.03% of global total, but half the population of island countries live within less than a mile of their coastlines; coral atolls no more than 3 meters above sea level Typhoon/hurricane damage will increase by 10-26% for each 1 degree warming of sea Deforestation (17-20% of GHG emissions) Global Humanitarian Forum estimates CC already killing 100-300,000 people annually

6. May 2010 6 Why ICTs Matter ICTs (excluding broadcasting) contribute an estimated 2-3% of global Greenhouse Gas emissions Around 0.9 ton GtCO 2 e in 2007 Telecoms contributed around one quarter of this total Airplanes and shipping about 3% each Source: Gartner Group

7. May 2010 7 What trends do ICTs have at the device level? Market doubles every 5 years E.g. Broadband expanding to more users Until market saturates Then upgrades replace obsolete devices New devices become a must have E.g. HDTV, Smartphones Annual growth rate of internet traffic is high 1.8 billion Internet users worldwide Highest growth in data traffic; Internet of things All three trends increase ICT demand for energy the GeSI Smart 2020 report predicts growth in ICTs energy use of 70% over the period 2007-2020

8. May 2010 8 REDUCING ICT SECTOR EMISSIONS PCs : > Efficiency gains and longer product life. > Shift from desktops to laptops > Shift from CRT to LCD screens > Potential breakthroughs – solid state hard drives, new LCD screens, new battery technology, quantum and optical computing Data Centres: > Higher rates of virtualisation; more efficient virtualisation architectures > Low energy cooling > Utility/cloud computing, Software as a service Telecoms Devices : > Smart chargers > 1W or lower standby devices > Broadband routers and IPTV boxes footprint increases over timeframe due to higher penetration from small base today Telecoms Infrastructure: > New network management tools > Network optimisation packages > Solar-powered base stations > Potential breakthroughs – night battery operation, natural ventilation, network sharing REDUCING ICT SECTOR EMISSIONS

9. May 2010 9 Mitigating the impact Directly, e.g. through energy-saving Next-Generation Networks (NGN) should reduce GHG emissions by 40% Modern radio technologies reduce energy consumption by transmitters ~ 10 times Indirectly, e.g. ICTs for carbon abatement Video-conferencing to reduce business travel in Europe by 1% would save 1 m CO 2 ton Systemically, e.g. by dematerialisation Intelligent Transport Systems could reduce vehicle carbon emissions below 130 g per km

10. May 2010 10 Placing Future Data Centres… BT will place Energy Efficient, Green, Sustainable facilities based on: Electricity is low cost, consistent, and available securely and in an abundance from renewable sources Fresh Air and Free Air cooling can be utilised all year round Network bandwidth low latency and high capacity is readily available and inexpensive Land is low cost, with plenty of space for growth/expansion BT will transform existing sites as much as possible to meet the standards of the new BT green data centre vision

11. May 2010 11 Life Cycle Assessment (LCA) studies calculate the relevant environmental impacts of the life cycle per functional unit. Production Phase Use Phase End-of-life Phase Design Phase Residues Resources ICT Services Life Cycle of an ICT product Recycling The Life Cycle of ICT Hardware

12. May 2010 12 ICTs at work for monitoring climate change WMO World Weather Watch, incorporating: Global Observing system Global Telecom System Global Data Processing system Remote sensing Environmental monitoring Tsunami early-warning system Digital climate forecasting models GPS-enabled telemetry Ubiquitous sensor networks

13. May 2010 13 ICTs for adaptation: ITU Role Telecommunications/ICTs for disaster preparedness Tampere Convention PP-06 Resolutions 36 and 136 on use ICTs for humanitarian assistance WRC Resolutions 646, 647, 673 on use of radiocommunications for environmental monitoring, public protection and disaster relief WTDC-06 Resolution 34 on the role of ICTs in mitigation of effects of disasters and humanitarian assistance Partnership Coordination Panel on Telecoms for Disaster Relief (PCP-TDR) E.164 country code (888) for UN OCHA Recommendations E.106 on call priority and X.1303 on common alerting protocol

14. May 2010 14 The ICT Enabling Effect ICT responsible for 2-3% of global CO 2 emissions How can we reduce ICT own emissions Next Generation Networks ICT key to reduce the other 97% of CO 2 emissions The enabling effect by a factor of five ICT as key enabler to reduce emissions in other sectors

15. May 2010 15 CO 2 reduction through convergence with ICT in other industries CO 2 reduction through convergence with ICT in other industries CO 2 reduction of infrastructure and products in ICT industry CO 2 reduction of infrastructure and products in ICT industry Green ICT covers all activities on Green of ICT & Green by ICT Green of ICT Green by ICT

16. May 2010 16 GREEN By ICT The opportunities where ICT could play a driving role include: Smart grid Smart buildings Smart logistics Smart motor systems Dematerialisation

17. May 2010 17 DEMATERIALISATION The substitution of high carbon products and activities with low carbon alternatives: > Replacing face-to-face meetings with tele- and videoconferencing > Remote working > Paper with email/online billing > CDs with online music
