Proposal to Standardize Methodology for Evaluating
Energy Saving Impact of ICT Services
Submission Date:
July 3, 2008
Initiatives of Japan
• Japan enacted the Kyoto Protocol in Kyoto in
December 1997.
• Japan proposed the approach for “Possible
Sectoral Efficiency Indicators” post-Kyoto
Protocol for CO2 reduction.
• Japan proposed a target of reducing the GHG in
the world by half by 2050.

Negative & Positive Aspects of ICTs
• Negative aspects:
– Generation of waste
• Positive aspects:
– Improvement of industry efficiency
– Saving of resources and energy
CO2 emissions (Bt-CO2)
– Consumption of resources and energy
All Other Sectors

Activities of Japan
• “Study Group on ICT System and Network for Reducing
Environmental Impacts” (MIC [2007.3])
– Guideline for enterprises and municipalities for enlightenment
on reducing environmental impact by using ICTs
% of CO2 emission
• “Study Group on ICT Policies for Resolving Global
Warming Problems” (MIC [2008.4])
Consumption of ICTs
30Mt-CO2
68Mt-CO2
In 2012, ICTs will contribute to a
reduction of 38 (= 68-30) million
tons of CO2 in ICT and
broadcasting sectors.

Necessity of Methodology
• There are no methodologies for evaluating and
quantifying GHG reduction of other sectors by
using ICTs.
– Valid?
– Common to other countries?
– Acceptable for other sectors?
• Therefore, we DO need a standard for the method.

Highlight of Current TTC Activities
• TTC Task Force on ICTs and Climate Change (February 2008~)
– Purpose: Developing methodology for how ICTs can contribute to
climate change and discussing matters that should be standardized
internationally
– Members: Telecommunications providers, vendors, and MIC
• ITU Kyoto Symposium (April 2008)
– Energy saving contributions by using ICT services
– Need for an internationally agreed common methodology for measuring
environmental impact of ICTs on climate change
– Proposal for establishment of a new FG
• Proposal to TSB of a New FG and ToR (May 2008)
• ITU London Symposium (June 2008)
– Proposal about ToR of new FG
New FG “xxxxxxxxxxxxxxx”
at TSAG of ITU-T (July 2008)

Scope of Focus Group
• Internationally agreed common methodology
for measuring the following impacts of ICTs
on climate change:
- Direct impacts on ICT systems and services
=> Power reduction methods
- Indirect impacts through application of ICTs
to various social and economic sectors
=> CO2 saving calculation methods
7
Proposed Methodology
• Energy consumption reduction through the use
of ICTs is defined as the difference between the
energy consumption reduction effect by using
ICTs and energy consumption of ICTs.
Energy

consumption ＝ effect by －

Proposed Strategic Collaborative
Direction in GSC (Resolutions)
• An environmental impact evaluation methodology is indispensable
for achieving both energy savings by an ICT system itself and
energy savings by other sectors using ICT services.
• To encourage PSOs to contribute to the ITU-T initiatives on ICT
and climate change in order to standardize both energy-saving ICT
systems and the methodologies for analyzing, evaluating, and
quantifying GHG reductions that may be achieved through the use
of ICTs.
• To support the establishment and early implementation of the
WTSA2008 resolution on ICTs and climate change.
This is a challenging proposal because this
methodology will influence all sectors of society,
including the ICT sector.

Next Steps/Actions of TTC in Support
of ITU-T Initiatives
• At a new FG meeting of ITU-T, TTC will support the
discussion for standardizing a methodology for evaluating the
energy-saving impact of ICT services in collaboration with
other PSOs.
– FG will hold its first meeting in September 2008, followed by a
meeting every two months.
– FG will submit the outcomes to the first meeting of TSAG
(April 2009) in the next study period (2009-2012) for their
consideration.
• Future TTC Contribution
– Proposal of the methodology
– Support in managing and operating FG
– Liaison with other related organizations
