Organizations may report several energy intensity ratios where this aids transparency or comparability. For example, they may calculate separate ratios by:

Business unit or facility
Country
Source type (See Definitions for the listing of non-renewable and renewable energy sources)
Activity type

Intensity is calculated by dividing the absolute energy consumption (the numerator) by the organization-specific metric (the denominator).Organizations may report the intensity of energy consumed within the organization or outside of it. If the ratio is calculated both for the energy consumed within the organization and outside of it, present such ratios separately.
Reporting on this Indicator should include the following contextual information as a comment to the metric value:

G4-EN5-b: Report the organization-specific metric (the ratio denominator) chosen to calculate the ratio.​
G4-EN5-c: Report the types of energy included in the intensity ratio: fuel, electricity, heating, cooling, steam, or all.​
G4-EN5-d: Report whether the ratio uses energy consumed within the organization, outside of it or both.
