Scope and goal of deliverable 1 l.jpg
Scope and Goal of Deliverable 1

Terms of Reference concerning to Deliverable 1

  • The FG, based on existing terms and definitions used in ITU, should:

    • • identify the terms and definitions (including units) needed to analyze the three major relationships between ICTs and Climate Change;

    • • identify differences between existing terms and definitions;

    • • develop and propose new definitions where necessary (gaps).

Objective and Goal of D1 (C66 from WG-A Chairman)

The scope of the deliverable 1 is to define relevant terminology and principles using each deliverables in order to eliminate pointless discussion arising from differences in understanding of them. Appropriate Terms, abbreviations, references, and principles that are used in FG ICT&CC are to be listed and defined in this deliverable. Terminology that should be clarified in ITU-T is to be organised without duplication or contradiction. The direction of this deliverable is to establish common basis for discussion.

Direction of discussion: Pointless arguments arising from differences in understanding of terminology are eliminated. Principles and rules need to be clarified.

1.2 Information and Communication Technology

Information and Communication technology covers the collection of technologies and equipment that deal specifically with processing, storing, and communicating information of all kinds, whether voice, data or multimedia, including all types of computers and communication systems.

For the purposes of this report, Information and Communication Technology covers :

• Computers, desktops, laptops, notebooks, PDAs and peripherals: workstations; laptops; desktops and peripherals such as monitors and printers and printing consumables, scanners, CCTV, cables

• Software: all kind of software including operating systems, backup / archival, database management, finance, network management …

• Digital content: music, press, radio, TV, video games …

• IT services: data centres and their component servers; storage facilities, building facilities, cooling facilities

• Information Systems and Telecommunication networks and devices: network infrastructure components;

More detailed definitions are:

- the SANCHO database (available in English, Spanish, French)

- the document 029-E from ITU-T titled : Draft definitions: Key telecommunication/ICT indicators.

1 6 definitions related to energy efficiency of ict l.jpg
1.6 Definitions related to energy efficiency of ICT

Terminology List

  • Energy Consumption Rating (ECR)

    ECR = Ef/Tf (expressed in Watts per Gbps)

    Tf = maximum throughput (Gbps) achieved in the measurement

    Ef = energy consumption (Watts) measured during running test

  • ECRW = ((α x Ef) + (β x Eh) + (γ x Ei)) / Tf (dimensionless)

    Tf = maximum throughput (Gbps) achieved in the measurement

    Ef = energy consumption (Watts) measured during running test “Step 1”.

    Eh = energy consumption (Watts) measured during test “Step 2”.

    Ei = energy consumption (Watts) measured during test “Step 3”.

    α, β, γ = weight coefficients to reflect the mixed mode of operation

2.2 Positive impacts of ICT to reduce GHG emissions

Terminology List

  • Energy consumption reduction through the use of ICTs

  • Reduction in GHG emissions from reduced energy and resource consumption by utilizing ICT

  • Consumption of goods / dematerialization

  • Energy consumption

  • Distributed Energy Generation

  • Movement of people

  • Movement of goods

  • Improved efficiency of office space

2 2 negative impacts of ict l.jpg
2.2 Negative impacts of ICT

  • Increased GHG Emissions from the Entire ICT Lifecycle

    It includes resources and energy consumed in the process, such as the production and installation of ICT devices and networks, electric power consumed in their use stage, and energy consumed in the process of their disposal and recycling.

2 3 rebound effect l.jpg
2.3 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”. Research is currently on this topic.
