 KPIs

System(s) covered by the methodology
  • Cloud Computing Services and Data Centre Services, which comprise:
    • E-mail, calendar, document and other business applications
    • Consumer photo, video and music and other data storage applications
    • Search, social networking and database applications
    • Application hosting in the cloud
Goals
  • Quantifying the energy and GHG emissions associated with the delivery of cloud services, focusing on the “user” perspective
  • Providing with standard and repeatable methods for a better understanding of the energy and GHG impacts of alternative ICT service delivery solutions
  • Assessing GHG emissions of a cloud service provided by or associated with the use of data centres
  • Comparing GHG emissions of a cloud service with those from an equivalent non-cloud service
Generic features
  • All stages other than the use stage may be grouped together (embodied emissions)
  • Primary data should be collected for processes under the ownership or control of the cloud service provider
  • 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
  • Cloud services create emissions through data centres, network, and end-user devices. Depending on the specificity of cloud applications, certain aspects may to be included.
  • The functional unit should clearly describe:
    • The quantity of the service (e.g. number of users, size of storage capacity)
    • The duration of the service (e.g. per year, for the contract duration)
    • The quality of the service (e.g. in terms of recovery/availability)
  • The following processes are not attributable to the GHG impact of cloud services:
    • Energy consumed during software development
    • Material and energy flows not directly related to equipment for hosting and fulfilment of the service
    • Maintenance of capital equipment
  • Cloud services must include:
    • Hosting and fulfilment of cloud applications (e.g. servers, storage devices)
    • Internet transfer and user access
    • Energy, water and other materials consumed by the above processes
  • Guidance is provided on allocation methods of emissions and ICT devices of the data centre; the method should seek to separate fixed vs. variable emissions of the site. The document indicates specific data required for the allocation.
  • Refer to [GHG Protocol – Hardware] and [GHG Protocol – TNS] for the calculation of GHG impacts of the component parts of the infrastructure that support a cloud service
