System(s) covered by the methodology
  • Telecommunications Network Services. The services comprise ICT goods, including:
  • Service provider equipment (e.g. routers, mobile transmitters, servers)

  • Support equipment such as cabling and racking

  • Customer premise equipment (CPE) such as telephones, computers and videoconferencing systems as well as equipment deployed on the customer‘s premises

  • Operational (people-related) activities associated with telecoms network services such as installation, maintenance and customer service

Goals
  • Providing supporting data for identification of a life cycle stage, subassembly or process that have significant GHG emissions (hot spot)
  • Assessing energy use and GHG emissions of a TNS
  • Prioritising reduction efforts across the product life cycle (from a service provider or user perspective)
Generic features
  • All stages other than the use stage may be grouped together (embodied emissions)
  • Critical review by a first or third party is required
  • Offsets, avoided and delayed emissions are not to be included in the inventory results
  • Functional unit:
    • For all final products, the unit of analysis is defined as a functional unit

    • For intermediate products where the eventual function is unknown, the unit of analysis is defined as the reference flow

  • Cradle-to-gate and gate-to-gate inventory results should be reported separately (if not limited by confidentiality)
  • Companies shall disclose and justify any exclusions of attributable processes in the inventory report
  • Companies shall collect primary data for all processes under their ownership / control
  • Companies shall assess the data quality of activity data, emission factors, and/or direct emissions data
ICT-specific features
  • The scope and the function of the service being assessed shall be clearly described, focusing on the quantitative and qualitative aspects of the function
  • Examples of functional units are provided:
    • One minute of use (e.g. phone call)

    • One Megabyte of data transferred

    • Service Contract life (e.g. three years)

    • Annual usage (i.e. one year)

  • TNS are subdivided into 3 elements, that can be individually assessed:
    • Customer Domain: All ICT equipment and support equipment (e.g. cabling) that is part of the TNS and is deployed at the customer‘s premises – end-user equipment is not part of the scope

    • Service Platform: All ICT equipment and support equipment used by the TNS provider in delivering the service being assessed

    • Operational Activities: Any people (labour) activities and non-ICT support equipment that are directly engaged and dedicated to the assessed TNS

    • Refer to [ETSI 103 199] for allocation guidance specific to ICT

Examples of implementation / experience feedback
