(New Question) Motivation
SG5 is responsible for studying ICT environmental aspects on electromagnetic
phenomena and climate change. In addition, SG5 has been appointed as a lead
Study Group to advance the work on ICT and climate change.
Through many discussions in the Focus Group on ICT and Climate Change
(hereafter “FG ICT&CC”), the importance of determining the impact of ICTs on
climate change from the standardization viewpoint and within the competencies of
the ITU-T was identified. It was also identified that this impact consists of
ICT direct energy consumption and greenhouse gas (GHG) emissions over the entire
life cycles (direct impact) of the ICTs and the impact through the use of ICTs
in other relevant sectors (indirect impact) that under certain conditions can
result in mitigation of primary energy, GHG emissions, and use of materials such
as rare metals.
The necessity of developing concrete and common methodologies including a
unified metric to describe and estimate objectively and transparently present
and future user energy consumption of ICTs over their entire life cycles was
also recognized. A methodology for assessing the environmental impact of ICTs
should be based upon the life cycle assessment (LCA), which was standardized in
the ISO 14040 series, and should be used to evaluate the eco-efficiency of
individuals, businesses, and ICT-related societies.
Towards constructing sustainable societies on the environment by utilizing
ICT, creating common methodologies for ICT environmental both impacts assessment
with objective, transparency and practical use is the key motivator for this
Question. For this motivation, it is necessary to discuss above aspects not from
political viewpoints but from technological viewpoints within this Question.
This method covers also the methods to verify by measurement the assessment
of direct ICT impact and of potential indirect mitigation impact.
Question
Study items to be considered include, but are not limited to:
- What are the general principles to be used to establish the methodology
to assess impact, which consists of the impact of ICT emissions over their
entire life cycles and the impact of the mitigation achieved through the use
of ICTs in other relevant sectors?
- How can the specific characteristics of the direct and indirect impacts
of ICT (e.g., changes in environmental loads by the introduction of ICT
services) be determined? This aspect includes the following.
- What methodologies are needed to enable GHG reduction by choice of
alternative technologies to deliver telecommunication services (‘own’
emission reduction)?
- What methodologies are needed to enable comparisons to be made concerning
alternative services (e.g., travel substitution)?
- What methodologies are needed to enable comparisons to be made concerning
efficiency improvement (e.g. building energy management)?
- What methodologies are needed to compare alternative lifecycle choices?
The calculations need to consider the entire lifecycle, extraction,
production, transport, usage phase and end-of-life.
- What are the formulas to calculate the environmental impacts of each
activity? What are the criteria for calculating changes to the environmental
impact through using ICT services/solutions?
- What are the considerations for the functional unit selection and the
system boundary selection?
- What are the allocation procedures for assessing ICT environmental
impact based on LCA?
- How to collect reliable data, in particular data impacting very
significantly the results e.g., the electrical and fossil energy to build a
silicone device, the silicone chip being the foundation of all ICT devices?
How to take into account the evolution of data over time?
- What are the common environmental loads and how to express the
environment load in absolute, relative value and intensity per unit? What
can be used as background data for objectively and transparently assessing
the environmental impact of ICT? What are the regional dependencies that
might be necessary to consider in determining the environmental load
intensity per unit?
- How to evaluate the methodology (measurement, statistic sampling, case
studies, etc.) including different regional or national aspects?
- How to use methodology to assess the need for Carbon labeling programme
and its scope
Tasks
Tasks include, but are not limited to:
- Develop Recommendations on methodology for environmental impact
assessment of ICTs considering general principles, criteria for evaluating
ICT impact, system boundaries, functional units, and Environmental load
intensity
- Develop Recommendations on collecting and calculating reliable rough
data to inject in the assessment model (e.g. J per cm² or g of silicone
wafer used in constructing in electronic chip)
- Develop Handbooks as necessary making reference to available databases
related to common environmental load intensities
- Coordinate with other SGs and other bodies on a regular basis to
collaborate effectively
