System(s) covered by the methodology
  • Desktop Managed Services, which comprise:
    • Service Desk
    • End User Device
    • Desk Side Services
    • End User Infrastructure
    • Service Delivery Management
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 DMS
  • 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 of the DMS being assessed shall be clearly described, e.g. based on the examples provided.
  • The functional unit needs to define the magnitude (e.g. number of users supported), the duration (e.g. length of service) and the quality (e.g. type of support, response times) of the service.
  • The decommissioning / standing down of support teams at service end may not necessarily be considered a major factor to generation of emissions but screening should be employed to ascertain materiality.
  • Some processes may be excluded from the GHG emissions calculation, such as: upstream emissions of capital goods (e.g. vehicles used for support staff transportation, buildings that support the service), lighting and heating for users of the DMS, travel of support staff which are not directly related to the provision of DMS.
  • The allocation of DMS between independent products should involve pro-rating of usage of the shared component. Recommended allocation methods are provided for several examples of shared components.
  • Technical refresh (at different times or stages of parts of the estate) should be accounted for by assuming a level of refresh for the duration of the service (i.e. usually duration of contract) for different categories of equipment. If the refresh is different in practice from what planned, this should be treated as a new service and recalculated.
  • Refer to guidance defined in other chapters of the GHG Protocol ICT sector guidance e.g. for requirements on hardware or cloud and data centre services.
