Présentation de Viktor Arvidsson (Ericsson France) lors du séminaire "Next Generation Wireless Green Networks" organisé par Supélec le 5-6 novembre 2009.

2. Life cycle assessments (LCA)
Scope: our products/services life cycle
Supply chain Ericsson Use phase End of life
Manufacturing & office sites Transports Products energy Collection/treatment
Transports Office & manufacturing sites consumption Recycling of metals
Raw materials & chemicals Business travel Offices & stores Landfill
Vehicle fleet Resource depletion
LCA standards: ISO 14040, 14044

Now about 20-25 kg CO2 per year – Same as driving a car for 1 hour

4. Benefits of doing LCA
› Getting a complete, holistic picture (including
manufacturing and end-of-life-treatment)
› LCAs gives strength in any environmental communication
with authorities, customers, etc.
› All emissions can be included, not just CO2, for the whole
supply chain, from concrete in tower fundaments to ICs
used in mobile phones

10. ICT services and APPLICATIONS
› Teleworking, flexi-working
› Virtual communication, virtual presence
› m/e-commerce, ”Internet shopping”
› From products to services dematerialization
and to digital media dematerialization
› m/e-health, m/e-governance, m/e-learning,
etc.
› Smart manufacturing and transport systems
› Smart buildings and the future smart electric
grid
› Information, monitoring and control
› ”21st Century Infrastructure”
ICT can substitute, reduce and make the remaining use of buildings,
vehicles, etc. much more efficient - LCA is the method to prove it

11. ICT reduction potential (estimates)
› Smart 2020 -15% (ICT about 2%)
› WWF -22% (ICT about 2%)
› ”Climate Positive”
5% 10% 20%
The ICT lever can give large momentum to reductions

12. Conclusions
› ICT respresents about 2% of the world’s CO2
emissions
› The 21st century infrastructure that ICT has created
can deliver basic services that contribute to
sustainable development for the world's population
› LCA is the method to be used when validating the
environemntal impact and reduction potentials from
existing and future ICT services and applications
