  1. ICTs as a green technologies for Sustainable Development - ICT & Climate Change Policies and Actions- Koichi Fujinuma Ministry of Internal Affairs and Communications JAPAN ITU Symposium on ICTs, the Environment and Climate Change Accra, Ghana, 7-8 July 2011

  2. Global Warming and ICT 1 ICTs themselves produce CO2 emissions due to consumption of electrical power to operate equipment/systems. On the other hand, ICT usagecan contribute to a reduction in CO2 emissions due to a marked improvement in the efficiency of production, consumption and business, also that of traffic alternatives,and a reduction in traffic volume. It is possible to make environmental measurements and predictions using ICT. Improved energy efficiency Improved efficiency of production and consumption • Supply chain management • e-publication and distribution • Paperless office General households • ITS (Intensive control of ETC, VICS, and traffic lights) •BEMS (Building energy management system) •HEMS (Household energy management system) Reduced movement of people and products Environmental measurements and predictions Production/ distribution/ transportation Offices/shops • Online shopping, online trading • Telework, TV conferencing • Music, video, and software distribution • e-applications (tax declarations, online receipts) • Radar for measuring CO2 • Sensing network • Global simulator Use of ICT Contribute to tackling global warming issues by promoting wider use of ICT

  5. 4 Japan’s Climate Policies and Actions (ICT&CC related Issues) The New Growth Strategy (Cabinet decision) (June, 2010) Toward becoming the world’s top environment and energy power througha comprehensive policy package Japan will play a leading role in a low-carbon society, having set a Japanesetarget of reducing greenhouse gas emissions by 25 percent by 2020 compared tothe 1990 level; this target ispremised on the creation of a fair and effectiveinternational framework that includes all major economies and an agreementon ambitious targets by each of them. Under an initiative to be known as“Challenge 25, ” Japan will mobilize all possible policy tools to advance thisinitiative together with the Japanese people. The New Strategy in Information and Communications Technology (May, 2010)  ○Goalsfor 2020 Smart grid network shall become a common practice. We shall also see thehome and business sectors reducing CO2 emission as the Information and communications technology-aided zero-energy buildings becomes a reality in typical new homes and in all new public buildings.

  6. MIC‘s “ICT Restoration Vision 2.0”(April, 2010) 5 Build the infrastructure underlying a knowledge and information-based society ●By around 2015, achieve 100% of “New Broadband Super Highway” (all households use broadband services). Maximize Japan’s potential ●Through the “Japan x ICT” strategy, achieve an annual average potential growth rate of approximately 2.6% over the next 10 years (2011 – 2020). Make contributions internationally to help solve problems facing the world ●Achieve CO2 emissions reductions of more than 10% from 1990 levels by 2020 through the ICT. → Promote ICT green project

  7. MIC’s ICT Green Project 6 • Greening of the ICT system itself (GreenofICT) • ・Responding to increased power consumption by expanding usage of ICT systems (e.g., R&D to conserve power in the overall system from carrier equipment to in-home equipment) • Greening of other fields through extensive use of ICT (GreenbyICT) • ・E.g., formulation of communication standards for achieving early practical implementation of smart meters • ・Establishing best practices such as by demonstration testing to promote usage of ICT • International cooperation • ・Establishment of methodologies for evaluating GHG reductions by using ICTs and contribute to International Organizations. Green of ICT Green by ICT Carrier data center Reducing CO2 emissions at companies and homes by using ICT and making power consumption more efficient Office Communication network Home 3)International cooperation (e.g., establishing techniques for evaluating effectiveness in reducing CO2 emissions) Reduction of CO2 emissions

  9. Green-of-ICT: Environmental Guidelines for the ICT Field 8 Members of the Conference on Environmental Guidelines for the ICT Field ・Telecommunications Carriers Association ・Communications and Information Network Association of Japan ・Telecom Services Association ・ASP and SaaS Industry Consortium ・Japan Internet Providers Association * MIC participates as an observer. Evaluation standards for equipment and data centers • (1) Equipment •   ・Small routers ・L2 switches ・Transport equipment (WDM)・PON equipment(GE-PON) ・Broadband base station equipment (WiMAX) ・External power supplies (AC adapters) ・Server equipment • An estimate based on evaluation indicators was determined on a 5 point scale, and the ranking was indicated by number of stars (★-★★★★★). Of these, two stars (★★) was taken to be the rank including the standard value. • (2) Data centers • For the moment, PUE※ was adopted as one indicator of energy conservation at data centers. * PUE (Power Usage Effectiveness) = Power consumption of entire facility/Power consumption of ICT “Self-evaluation checklist” and “Eco ICT Mark” • Telecommunications carriers evaluate their own efforts to reduce CO2 emissions according to a checklist, and publish the efforts they are making. • If a company describes their specific efforts for all mandatory items, then they can use the “Eco ICT Mark”

  10. Green of ICT: Reducing the Environmental Impact of Data Centers Data Center in central Tokyo suburbs PUE1.5~2.5 PUE/CO2 emissions surveillance/management server 9 As cloud technology and other forms of ICT advance, data center usage is expected to rise dramatically. This will be accompanied by increased power consumption by data centers. Air conditioning and power distribution account for more than 50% of total data center power consumption. Therefore, by holding down such power consumption, it is possible to reduce the power consumption of the entire data center. MIC is working to establish standardized models by conducting highly effective demonstration experiments. Integrated operation and management (Load distribution) Data Center in low-temperature region Cooling through air conditioners PUE1.2~1.5 Heat Cooling through introduction of outside air High-speed network Virtualization (shared platform) CO2 CO2 Heat Heat Air-conditioning method using outside air, and snow and ice, etc. Conversion loss, small Management server High-voltage DC power supply system Power supply facilities Within IT devices Conventional air conditioning Ventilation air conditioning Integrated operations and management using cloud technology DC 300V or more Direct air conditioning Weather data Commercial grid Evaporative air conditioning Combinations of different air conditioning methods and their efficient operation

  11. Green-of-ICT: Reducing power consumption in the ICT field 10 ・In the BaU case (where no additional measures are implemented), total power consumption in the ICT field will rise sharply to over 51 million tons (125.6 billion kWh) by 2020 due to increased ICT usage. ・In the New Measures case, which includes R&D and demonstration experiments (such as optical communication network technology), ecological ICT equipment and data canters, and promoting cloud computing , power consumption could be cut back to under 30 million tons (72.3 billion kWh).

  13. Green-by-ICT: teleworking 12 Excerpt from “A New Strategy in Information and Communications Technology,” IT Strategic Headquarters, May 11, 2010 We shall advance the development of an appropriate environment and public education to help promote teleworking. Teleworking contributes to prompting the aged and physically impaired to engage with the world, creating employment opportunities for persons of diverse employment needs — for example, women who are forced to stay home to raise their children or to care for someone — and revitalizing local communities. Timetable: Reach 7 million home-based teleworkers by 2015 Home-based teleworkers: ~3.27 million (2009) Reference: State of Telework Adoption in Japan Teleworkers accounted for 15.3 percent of the total labor force in 2009 (“Telework Population Survey 2009,” Ministry of Land, Infrastructure, Transport and Tourism) Telework had been introduced at 19.0 percent of private businesses in 2009 (“Telecommunications Usage Trend Survey 2009,” Ministry of Internal Affairs and Communications) Have specific telework plans Total Employed Self-Employed Percentage of home-based teleworkers

  14. Green-by-ICT: Demonstration experiments of ICT systems for Smart Community 13 To support the development of environmentally friendly cities, this project will build and demonstrate ICT system infrastructures suited to local characteristics. The project will establish technical standards for ICT equipments/services necessary to reduce environmental loads, and promote production of local power resources (green energy, etc.) and optimization of consumption.

  19. Green-by-ICT: Estimate CO2 Emission reduction through the use of ICT 18 At current ICT usage levels (i.e., BaU case), a CO2 reduction of around 95 million tons would be achieved in 2020. This could be boosted to 150 million tons such as by installation of smart grids, BEMS/HEMS, and paperless office systems in a range of industries (the New Measures case). Note)a percentage of total greenhouse gas emissions in Japan for 1990

  20. Estimate of reductions in CO2 emissions 19 ○ Green by ICT ICT can potentially reduce CO2 emissions by up to 155 million tons in 2020. This is equivalent to a 12.3% reduction in total emissions relative to 1990 levelsin JAPAN. ○ Green of ICT In terms of the amount of CO2 generated by ICT equipment, new strategies are expected to reduce CO2 emissions to around 30 million tons, roughly equivalent to CO2 emissions in 2012.
