SESSION 3, OCTOBER 7, 2013Application of methodologies for environmental impact assessment (life

cycle assessment (LCA)

Presented by Dr. Anders S.G. Andrae




1.Mobile phones: Assessment of reasonableness/validity

of simplified LCA approaches compared to “full” LCA

• No life cycle stage should be omitted in simplified LCA

• Nor any life cycle impact assessment mid-point categories

2.Rationale for sensible usage of LCA of ICT

• LCA argued to be unfit for external comparisons of ICT systems• LCA argued to be unfit for external comparisons of ICT systems

• Order of magnitude estimations are feasible

3.Smartphones:Wide scope sustainability assessment of

footprint

• Networks constitute a large share of the impact – a share which

will increase until 2030

• Climate Change is not enough for assessing sustainability

4. Tools measuring data center energy usage in real time

• Public data are lacking for expanding the assessment with

environmental impact analysis10

Issues raised

1. Also simplified LCAs of mobile phones have to be done with

great care.

1.Data base vendors are not providing different scaling.

2. Do other sectors face same LCA challenges as ICT? E.g.

washing machines&TVs are rated. Washing machines&TVs eco-

rating is not based on LCA, only use power. Result differences

washing machines&TVs are rated. Washing machines&TVs eco-

rating is not based on LCA, only use power. Result differences

for upstream would likely not be large enough.

2. Is LCA good enough or not for ICT? Depends on application

2. Is LCA not good for performance legislation? No, as threshold

setting seems impossible per product.

3. Why do the Networks increase so much 2010-2030? High

data traffic and the energy efficiency can not keep up

4. MTM with API are already used for metering. 11


1. Simplification of mobile phone LCA is possible if done with

great care and include all traditional mid-point impact

categories!

• Check if ITU SG5 Q16 Basic LCA update have similar simplified scope as

presented study regarding metrics and impact categories

• Suggest LCI db providers of needs of scaling

2. Use ETSI/ITU standards but not for external comparison!

• Find ways to reach understanding with all stakeholders

3. Always include the Network in Smartphone technology

assessment!

• The ITU SG5 Q16 could learn from the study presented when

developing further its Eco (Sustainability) Rating of mobile phones

4. Add environmental impact data to data center power

calculations!12

SESSION 4

Application of methodologies for energy efficiency measurement




Shen: China Ministry is working on and testing Network EE

Scheck: the role of UEs in EE standardization is crucial,

both for RBSs and Network EE

Grosso: Energy Aware equipment needs to be measured in

a load related waya load related way

Ajmone: Network EE tests and simulations performed in

TREND project

14

Issues raised

Network Energy Efficiency hard to be measured due to the

complex “environment” (different RATs, different site

configurations,…)

Some tests are anyway ongoing and the hype is very

strong in latest months on EE both for RBSs and Network

Significant role of UEs: how to consider them in current Significant role of UEs: how to consider them in current

standardization activities?

Energy Aware equipment and load related measurements

to be taken into account

15


Continue the current work ongoing in ETSI for RBSs and

Mobile Access Networks EE, reaching the possible

alignment among SDOs

Important cooperation with ITU and 3GPP to ease the

overall adoptions of the possible standards

Tests VERY important to validate RBSs and Mobile Access

16

Tests VERY important to validate RBSs and Mobile Access

Network energy efficiency standards

SESSION 5Findings from environmental impact assessments of ICT products,

networks and servicesPresented by Pernilla Bergmark, Ericsson AB, associate Rapporteur of Q18/5 ITU-T SG5




ICT footprint forecasted to grow slightly from 1.3% of total global

CO2e emissions 2007 to 1,9% 2020. Total electricity use to grow from

4 to 5% by 2020 according to Ericsson presentation

• PCs and data centers most important contributions

• Connectivity of devices considered – limited impact

For the Swedish case study end-user equipment is a main

contributor, Overall energy consumption increased from around 1,1 contributor, Overall energy consumption increased from around 1,1

TWh to 2,2 TWh between 1990 to 2010.

Expected total electricity use to grow from around 8% to 10%

between 2012 and 2017 according to Huawei presentation.

The presenters agreed that all studies led to the conclusion that a

continuous growth in CO2e emissions and energy consumption from

ICT sector is foreseen – but to a limited extent.

18

Issues raised

Impact from end-user equipment and data centers

growing in importance

Exaggerated figures and incorrect bencgmarking with

things like fridges and air industry are popping up from

time to time and are spread widely

• ICT industry need to provide reasonable data to academia and • ICT industry need to provide reasonable data to academia and

analysts

No unambiguous definition of ICT sector – several

definitions exist

Age of data critical for the transitional ICT industry

Extensive peer reviewing demanded to get high quality

research results published in this area

19


Swap – share- sleep – supply

• Swap: old equipment with low energy efficiency to be replaced

• Share: cloud etc

• Sleep: load adaptive energy consumption

• Supply: Green electricity

Focus on end-user equipment – production and energy

20

Focus on end-user equipment – production and energy

consumption

Operators to focus on core sites/data centers

Upstream indicator values needed

Focus on most important equipment

Low energy consumption is key

GAL: control plane can balance the trade-off between

performance and energy consumption

GAL: control plane can balance the trade-off between

performance and energy consumption

GHG reports from NRENS:

• what kind of metrics can be used for comparison purposes – how

a common sustainability policy can be defined and applied?

• what standard to use for verification purposes – implications to

the design of the online tool?

27


Support collaboration between research projects and

standardization organizations

Deployment of 5G mobile networks – try to fulfill 5G

challenges with a factor of 10 lower energy consumption than

todaytoday

GAL to evolve as a standard – design and deployment of

control plane green strategies

Shared sustainability policy among NRENs –extraction of

useful results based on the collected data – engage research

and academic community
