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

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
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
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
