Please note that the factsheet below was developed based on a draft version of the GHG Protocol ICT Sector Guidance. The factsheet will be soon updated based on the final version of the Guidance (published in July 2017) to integrate any changes.

System(s) covered by the methodology

ICT hardware (IH), including computers and peripheral equipment; communication equipment; consumer electronic equipment; and various ICT components and goods

Goals
  • Providing information on several calculation methods and guiding the practitioner in choosing the appropriate method, depending on the intended assessment
  • Assessing GHG emissions of an ICT hardware (or a product family), which may then focus attention to reduce the emissions
  • Assessing GHG emissions due to the hardware in a complex ICT system (e.g. as part of a TNS or DMS, see [GHG Protocol – TNS] and [GHG Protocol – DMS])
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 functional unit description includes magnitude, duration and quality of the IH
  • A screening assessment is recommended to focus data collection efforts; in particular for ICT hardware that is kept operating for long periods of time
  • Refer to [ETSI 103 199] for boundary settings and allocation specific to ICT
  • Some processes are excluded from the IH assessment, such as: facility operations, corporate activities, and capital goods (e.g. machine used in assembling IH product)
  • Four calculation methods may be used to assess cradle-to-gate GHG emissions of IH; capabilities and drawbacks are detailed for each of them.
    • Component characterization
    • Hardware parameterisation
    • Life cycle stage ratio profiling
    • Environmentally extended input-output (EEIO)
  • The product lifespan is a very important factor as it can have very significant impact on the total life cycle GHG emissions from an IH product. In all cases, documentation of the modelled product life and the rationale for the modelling is imperative.
  • The use profile needs to reflect the time spent in the different power states
Examples of implementation / experience feedback

The Appendix 1 of the document present the calculation of GHG emissions by the component characterisation method, for a SOHO wireless router
