1. 1 International Telecommunication Union Overview of FG Deliverable 1 Definitions Editor’s Group of Deliverable 1 Yoh Somemura, (NTT) chairman Takeshi Origuchi, (NTT) chief editor Jean-Manuel Canet, (France Telecom Group) co-editor Catalina McGregor, (UK) co-editor Geir Leirvik, (Juniper Networks) co-editor Hossam Allam, (CEDARE) co-editor Noriyuki Nakayama (NEC) co-editor Richard Price (BT) co-editor

2. 2 International Telecommunication Union Scope  The scope of FG Deliverable 1 was to create a common framework on which to build methodology, recognize gaps and define metrics to reach the goals of the Focus Group :  Understand and mitigate negative impact of ICT on climate change (raw material extraction, production, use phase, end of life), increasing in particular the efficiency of equipment, networks and organisations.  Understand and encourage positive impact (for instance travel substitution, product substitution, smart buildings… ) : reducing GHG emissions  Understand and encourage measurement and monitoring of climate change impacts 2 International Telecommunication Union

3. Domains of definitions  FG Deliverable 1 covers the following domains of definitions:  Climate Change  Information and Communication Technologies  Energy and links between energy and climate change  Climate change impact assessment  Relationship between climate change and economics impacts  Energy efficiency of ICT  Deliverable 1 principally refers to:  IPCC definitions  ISO definitions

5. Some positive effects identified CategoryEffects Consumption of goods By reducing goods consumption (consumption of paper etc.), energy consumption related to goods production and disposal as well as waste generation can be reduced. Power consumption / energy consumption By enhancing the efficiency of power and energy use to reduce consumption, energy consumption related to power generation, power transmission, etc. can be reduced. Movement of people By reducing the movement of people, energy consumption required for transportation means can be reduced. Movement of goods By reducing the movement of goods, energy consumption required for transportation means can be reduced. Improved efficiency of office space By using office space efficiently, power consumption for lighting, air conditioning, etc. can be reduced, thus reducing energy consumption. Storage of goods By reducing storage space of goods, power consumption for lighting, air conditioning, etc. can be reduced, thus reducing energy consumption. Improved work efficiencyBy enhancing work efficiency, resource and energy consumption can be reduced. Waste By reducing waste emissions, energy consumption required for environmental preservation as well as for waste disposal etc. can be reduced.

6. Rebound effect For some services brought by ICT such as telework or videoconferencing, the time gained for an end-user when using the telecom service may cause some additional usages – telecom or physical - which are difficult to track. These additional usages can be defined as “rebound effect”. There is ongoing research on this topic.
