Technology life cycle assessments (LCA)

Technology life cycle assessments Viktor Arvidsson

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

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

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

Ericsson life cycle carbon footprint 2008, based on Life Cycle Assessments Mton CO2e

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

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

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

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)

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
