  3. Introduction – Problems addressed • ISO 14040, ISO 14044 and the ILCD Handbook are recognized as normative LCA knowledge documents for “any” application • Based on the ISO standards, numerous LCA results for ICT with different quality and inconsistent result presentations have been provided – EU requirement on improvement • Standardization of LCA of ICT IS DEFINATELY NEEDED! • ETSI has responded to the gap • Work started in 2008-2009 and will finish in 2011 • The ETSI standard for ICT LCA is intended to be more specific than ISO 14040/ISO 14044, but less specific than, e.g., Japanese Product Category Rules for, e.g., notebooks © 2011 – Proprietary and Information of ETSI

  4. Features of the new ETSI LCA standard Based on ISO 14040, ISO 14044 and the ILCD Handbook Lifetimes – Defined Functional units (f.u.) – Basic f.u. defined System boundaries – Life Cycle Stages and Unit Processes Identified and Classified as Mandatory or Optional -The level of detail is relativelely high  good guidance for users Rules for Cut–off if they cannot be avoided Data quality evalution – Qualitative requirements defined for all life cycle stages and unit processes Allocation methods – Specified. E.g., 50/50 allocation prefereed between Raw Matr. Aquisition and Metal recycling. Detailed reporting instructions (diagrams, tables) ...will help, e.g., 3rd party reviewers 4 © 2011 – Proprietary and Information of ETSI

  6. General requirements - Lifetime Lifetime is (always) critical for the interpretation of the results of (ICT) LCAs Operating lifetime: The duration of the actual use period (consisting of both active and non–active periods) for the first user. Storage time is not included in operating lifetime. Operating lifetime shall always be reported and be based on available information on actual product use. 6 © 2011 – Proprietary and Information of ETSI

  12. Goal&Scope Definition – Support activities The term Support activities refers to, e.g., offices including ICT use for marketing, sales and R&D, and also to business travel, commuting and service vehicles. Support activities are optional to include but should be included where possible. The extent in which Support activities and other Optional activities are included for different parts of the life cycle shall be clearly described in the study report. 12 © 2011 – Proprietary and Information of ETSI

  17. Goal&Scope Definition – Networks System Boundaries • For the Network under study applicable types of nodes and infrastructure, as well as amounts of these, shall be defined. • Functional Block diagrams (HW and SW) essential for showing study scope • The impact from software development shall be included. • The Network shall be defined in terms of ICT equipment, Support Equipment and infrastructure. • Operator activities (mainly installation, maintenance and de-installation) shall always be included 17 © 2011 – Proprietary and Information of ETSI

  18. Goal&Scope Definition – Services System Boundaries • In order to calculate the impact of a Service, it is necessary to first assess the Network • Most often (i.e., in a multi–service situation) an allocation of an appropriate amount of the Network impact to the Service under study is needed • Service software development, Service use of consumables, Service sales and logistics infrastructure, Service associated travels and transports • Data centers are key • Service provider activities • Positive and negative impacts 18 © 2011 – Proprietary and Information of ETSI

  19. Goal&Scope Definition – Cut-off rules • Cut–offs shall be avoided as far as possible! • Table 1 constitute a significant share for typical product systems in ICT LCAs • The intention is that all Mandatory life cycle stages/unit processes of Table 1 shall be included • Model unavailable data based on known data • Mandatory to: • motivate clearly eventual cut–offs of mandatory life cycle stages/unit processes from Table 1 • describe clearly the cut–off criteria used within a study • consider unit processes/flows that have been cut–off for the sensitivity analysis. 19 © 2011 – Proprietary and Information of ETSI

  20. Goal&Scope Definition – Data quality requirements • Generic data: Data from any relevant data source which need not be specific for ICT applications and processes. Generic data is always secondary. • Specific data: Data emerging from, in this case, ICT specific applications and processes. This data could be either primary or secondary. • Primary data:Data collected/estimated/measured by a researcher, specifically for the LCA project; for example, pilot studies or customer or producer surveys. • Secondary data: Data that has been collected for another purpose, but can be analyzed again in a subsequent study; for example, LCA estimates by academia, government, or industry organizations. 20 © 2011 – Proprietary and Information of ETSI

  23. Life Cycle Inventory – Data collection • The LCA practitioner shall report for which processes transports/energy supplies have been added separately and for which they are “hidden”. • For many products (especially end–user equipment), periods of idling and power off are important to model the usage profile and shall be considered. 23 © 2011 – Proprietary and Information of ETSI

  24. Life Cycle Inventory - Allocation rules • Generic processes (G1–G7) shall be allocated as a whole to the life cycle stage in which they are used • Support activities… • Facilities… • Transports shall be allocated based on chargeable weight • Recycling: The 50/50 method shall be used to allocate use of recycled Raw Material between A1-A2 and D. • If used LCI data (e.g., for gold production) do not reveal the scrap% of metal, the 100/0 method is allowed. No metal recycling in EoLT allowed with 100/0. 24 © 2011 – Proprietary and Information of ETSI

  26. Life Cycle Inventory – Allocation rules – 100/0 26 © 2011 – Proprietary and Information of ETSI

  27. Life Cycle Inventory - Allocation rules for Equipment data to Networks • End–user equipment (e.g., PCs, smart phones) which is accessing more than one Network (e.g. 3G, WLAN) shall be allocated to these Networks based on use time • Impact from shared Network resources (e.g., transmission equipment, core nodes and data centers) shall be allocated to an access network based on data traffic 27 © 2011 – Proprietary and Information of ETSI

  28. Life Cycle Inventory - Allocation rules for Network data to Services • Data for End–users– and home/CPE equipment: • to be allocated based on active use time of the Service • Data for transport equipment: • to be allocated based on data traffic • The data center(s), where the Service is operated, as well as the Service provider activities shall be allocated based on number of subscriptions and Service users 28 © 2011 – Proprietary and Information of ETSI

  29. Life Cycle Impact Assessment The baseline model of 100 years of the IPCC (GWP100) LCIA method is mandatory (shall) as mid–point impact assessment indicator for climate change. For other mid-points Impact Assessment Categories than Climate Change and Ozone Depletion there are several Category indicators developed. If these mid–points are included in the study scope the ILCD Handbook shall be followed as close as possible. Also for best End-point assessment practise the ILCD Handbook for LCIA shall be consulted. 29 © 2011 – Proprietary and Information of ETSI

  30. Life Cycle Interpretation - how robust are the results and conclusions? The challenge of the completeness check is to overcome the paradox of evaluating the degree of completeness of the product system when not knowing 100% of it. If two or more ICT Equipment, Networks or Services LCA results do not differ significantly there is a risk of erroneous interpretations. The significance is determined for instance by magnitude in difference, modeling assumptions, and LCA software program calculation algorithm. 30 © 2011 – Proprietary and Information of ETSI

  31. Comparative LCA between ICT and business as usual (BAU) systems - reduction potential LCAs with the same goal&scope, system boundaries and functional unit need to be performed for both the ICT Service and the BAU Service it replaces Especially as identical as possible system boundaries for the Raw Material Acquisition and Production Phases. For the BAU Service the associated environmental impacts shall be estimated according to travel and infrastructure first order effects. The first order effects are those directly attributable to the Services. The reduction potential is the second order effect. Rebound effects are outside the scope. 31 © 2011 – Proprietary and Information of ETSI
