Implementation Templates

In short: fill-in-the-blanks templates for the analyses that most often need careful disclosure. They are illustrative, not prescribed: adapt them to your context. Three live on the pages they support; the fourth, for bundled CDN energy, is below.

Templates on other pages

• M_network materiality assessment, for deciding whether M_network can be declared unpopulated: Embodied Emissions: Network.
• Functional units for several user journeys: Choosing a Functional Unit.
• First-party and third-party O_client breakdown: Third-Party Attribution.
• Full disclosure (YAML): Disclosure Template.

CDN bundled-energy allocation

Use this when a CDN provider publishes a single bundled energy figure for your traffic. Clause 5.5 requires the allocation between components to be disclosed and forbids counting energy in more than one component. The rule for where CDN energy belongs, and a worked example, are on Network Emissions.

Supplier figure:
  - Source:                     [e.g. CDN provider sustainability portal]
  - Period:                     [e.g. 2026-01-01 to 2026-01-31]
  - Bundled energy:             [X kWh] for this application's traffic
  - Carbon intensity applied:   [y gCO2eq/kWh — source]
  - Bundled carbon:             [X × y] gCO2eq

Allocation rule:
  - Rationale:                  [e.g. cache-hit ratio split]
  - Split:                      [e.g. a% O_network (transmission) / b% O_server (facility or edge compute)]
  - Assumptions:                [e.g. cache hits are transmission-only;
                                 dynamic edge functions are compute-equivalent]
  - Data sources for split:     [e.g. CDN analytics dashboard]

Effect on the reported score:
  - O_network reported?         [yes / no]
  - If no: energy allocated to O_network ([a% × X] kWh) is excluded from
    the score. Name it, with its quantity, in the limitations disclosure.
    The split is not score-neutral.

Disclosure statement:
  "Allocation will move to component-specific figures if and when the
   provider publishes them."
