5. 5 Question 18/5: Methodology of Environmental Impact Assessment of ICT  The purpose of this Question is to develop Recommendations on methodology for environmental impact assessment of ICT and on collecting and calculating reliable data for the assessment model.  Following work items for series Recommendations are running in SG5 for methodologies: (2) L.methodology_ICT goods and services (3) L.methodology_ICT projects (4) L.methodology_ICT in organizations (5) L.methodology_ICT sector in countries Overview and general principles of methodologies Methodology for environmental impact assessment of ICT sector in countries Methodology for environmental impact assessment of ICT in organizations (1) L.methodology_general umbrella Methodology for environmental impact assessment of ICT projects Methodology for environmental impact assessment of ICT goods and services

6. 6 Strategic Collaborative Direction in GSC (proposed)  Encourage PSOs to contribute to ITU-T initiatives on ICT and climate change  to standardize energy-saving ICT systems and methodologies for analyzing, evaluating, and quantifying GHG reductions that may be achieved through ICT use to actively participate in standardization work in WP3/SG5  to produce recommendations on ICTs and climate change

7. 7 Next Steps/Actions of TTC in Support of ITU-T Initiatives  At a WP3/SG5 meeting of ITU-T, TTC members will actively contribute to discussions on standardizing a methodology for evaluating the energy-saving impact of ICT services in collaboration with other PSOs.  Future TTC Contribution Propose a methodology and power feeding, etc. Support management and operation of WP3/SG5. Liaise with other related organizations.

8. 8 Summary  International standardization on Environmental technologies for telecommunication, in particular to ICT and climate change is now underway in ITU-T.  We need to reduce environmental loads of ICT equipment and ICT sector, and we also expect that ICT can reduce environmental loads, particularly GHG emissions, in other relevant sectors.  For this purpose, prompt standardizations on objective and transparent methodology of ICT environmental impact assessment are required.

9. 9 Proposed Resolution  Proposed modifications to an existing Resolution * * (GSC14) “RESOLUTION GSC-14/08: (Plenary) ICT and the Environment (Revised),” GSC14-CL-015R2 (16 July 2009) Current Activities  Universal power adapter (ITU-T, IEC, IEEE)  Power feeding system using HVDC  Smart Grid & Cloud Computing (SDOs/Fora including ITU-T)  Intelligent Transport System (ITU-T) Encourage PSOs  to collaborate with “Smart grids” and “Cloud Computing”as HISs of GSC

11. 11 ItemContent Consumption of goods By reducing the consumption of goods (e.g. paper), it is possible to reduce the energy consumption involved with production and disposal and to reduce waste emissions. Electric power/energy consumption By improving the efficiency of electric power and energy use and reducing consumption, it is possible to reduce the energy consumption involved with electricity generation and supply. Movement of people By reducing the movement of people, it is possible to reduce the energy consumption needed for methods of transportation. Movement of goods By reducing the movement of goods, it is possible to reduce the energy consumption needed for transportation methods. Office space efficiency By using office space more efficiently, it is possible to reduce the electricity consumption of lighting and air-conditioning and to reduce energy consumption. Storage of goods By reducing the storage space of goods, it is possible to reduce the electricity consumption involved with lighting and air-conditioning and to reduce energy consumption. Business efficiency By improving business efficiency, it is possible to reduce resource and energy consumption. Waste material By reducing waste emissions, it is possible to conserve the environment and reduce the energy consumption needed to dispose of waste.
