Question 18/5: Methodology of
Environmental Impact Assessment of ICT
GSC16-PLEN-18
• 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:
Overview and general principles of methodologies
 L.1400 (approved in Feb. 2011)
Methodology for environmental impact assessment
goods, networks and services of ICT goods, networks and services

Strategic Collaborative Direction in
GSC (proposed)
GSC16-PLEN-18
• 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
(L.1410 is basic concept of methodology and useful
for establishing the other recommendations of
L.methodology series.)
– to actively participate in standardization work in
WP3/SG5
• to produce recommendations on ICTs and climate change

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 in
collaboration with other PSOs on standardizing
methodologies for environmental impact
assessment of ICT projects (L.1430), and ICT
sector in cities (L.1440) and countries (L.1450).
• Future TTC Contribution
– Propose a methodology and power feeding, etc.
– Support management and operation of WP3/SG5.
– Liaise with other related organizations.

Summary
GSC16-PLEN-18
 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.

Proposed Resolution
GSC16-PLEN-18
TTC proposes to modify an existing Resolution.*
The main points to be modified are as follows:
* “RESOLUTION GSC-15/08: (Plenary) ICT and the Environment (Revised),”
GSC15-CL-13 (2 September 2010)
Considering：
• New Recommendations of Methodology (ITU-T SG5)
• L.1400 (general umbrella): Approved in Feb. 2011
• L.1410 (ICT goods, networks and services): Consented in Sep. 2011
• L.1420 (ICT in organizations): Consented in Sep. 2011
• New Questions (ITU-T SG5)
• Q22/5: Setting up a low cost sustainable telecommunication
infrastructure for rural communications in developing countries
• Q 23/5: Using ICTs to enable countries to adapt to climate change
• GHG Protocol Initiative Scope 3 (WRI, WBCSD)
• Standardization of Quantification Methodology (IEC TC111)
• GHG emissions for electrical and electronic products and systems
• Standardization of ISO 14067 (ISO TC 207)
• Carbon footprint (CFP) of products--Requirements and guidelines
for quantification and communication

power/energy
consumption
Content
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.
Movement of people
By reducing the movement of people, it is possible to reduce the energy consumption
needed for methods of transportation.
By reducing the movement of goods, it is possible to reduce the energy consumption
needed for transportation methods.
By using office space more efficiently, it is possible to reduce the electricity consumption of
lighting and air-conditioning and to reduce energy consumption.
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.
By improving business efficiency, it is possible to reduce resource and energy consumption.
By reducing waste emissions, it is possible to conserve the environment and reduce the
energy consumption needed to dispose of waste.
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.
