Transcript

  • 1. Technology life cycle assessments Viktor Arvidsson
  • 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
  • 3. CO2 emission per mobile subscriber 200 Ericsson networks, AMPS LCA based data Annual CO2 /subscriber 150 100 GSM WCDMA [kg] 50 25 Year 1985 1990 1995 2000 2005 2010 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
  • 5. Ericsson life cycle carbon footprint 2008, based on Life Cycle Assessments Mton CO2e
  • 6. LCA of mobile broadband Annual kg CO2e / average subscriber in WCDMA/HSPA network 40 30 20 10 0 Mobile phone Mobile phone RBS site RBS operation Operator Core network use Total CO2e: Manufacturing 2001: 55 kg 2005: 35 kg 2007: 25 kg
  • 7. LCA of fixed broadband / PC Annual kg CO2 / average PC unit (world average) 250 200 150 100 50 0 PC PC use Modem Access Transmission "Internet“ and manufacturing & Transport data centers Operation Manufacturing
  • 8. Carbon emissions from ICT Study performed by Ericsson Research (2007) million ton CO2 e 500 Operation of end- 400 user equipment Network operation 300 Manufacturing & 200 business overheads 100 0 PC Data Fixed Mobile industry centers telecom telecom
  • 9. ICT and climate change Transport Forestry & Travel 17% 13% Agriculture Energy supply ICT: 14% 26% 1.4% CO2e Waste 3% 2% CO2 Industry Buildings 19% 8% Global CO2e 2007: Global carbon emissions 49 billion ton 7.4 ton per capita reported by IPCC (2007)
  • 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
