About

This metric is based on the Global Reporting Initiative (GRI) G4 Guidelines. It covers one of the requirements of Indicator G4-EN18 - ‘Greenhouse Gas (GHG) emissions intensity ratio'.

GHG emissions intensity expresses the GHG emissions per unit of activity, output, or any other organization-specific metric. Many organizations track environmental performance with intensity ratios. Intensity ratios are often called normalized environmental impact data. Intensity ratio defines an organization’s GHG emissions in the context of an organization-specific metric.

Intensity ratio defines an organization’s GHG emissions in the context of an organization-specific metric. Intensity is calculated by dividing the absolute emissions (the numerator) by an organization-specific metric (the denominator).

In combination with an organization’s absolute GHG emissions, GHG emissions intensity helps to contextualize the organization’s efficiency, including in relation to other organizations. 

Methodology

This metric is looking for Greenhouse Gas (GHG) emissions intensity ratio:

For WikiRate researchers:

Companies who align reports to GRI’s Sustainability Reporting Standards often include a GRI Content Index or Annex where GRI disclosures, with GRI codes, are listed.

  • Use the GRI Index, CTRL F, Command F or search button on source preview to search for this index and metrics within the report

  • Use G4 codes, G3 codes or keywords to quickly find values, keeping in mind that some companies report on the metric using different terms, e.g. G4-EN18 or EN18, GHG emissions or greenhouse gas emissions

  • Always check the metric question and methodology for the unit of measure or currency - researchers may need to carry out calculations or conversions before entering the final metric value

  • Add comments documenting exactly where within the source you found the information (page number) and include details of simple or complex calculations or conversions made to determine the metric value

  • If you are unable to locate a metric value in a source you can search for additional sources where the data is available and add a new source

Further guidance on how to research values for GRI-based metrics is available here, including detailed guidance on adding, editing and checking metric values.

Global Reporting Initiative compliance guidance for companies:

To calculate GHG emissions intensity - G4-EN18-a:

  • Select an appropriate ratio denominator to represent the per-unit output, activity, or any other organization-specific metric

  • Calculate the intensity ratio by dividing the absolute emissions (the numerator) by the organization-specific metric (the denominator)

Reporting on this Indicator should include the following contextual information as a comment to the metric value:

  • G4-EN18-b: The organization-specific metric (the ratio denominator) chosen to calculate the ratio.

  • G4-EN18-c: The types of GHG emissions included in the intensity ratio: direct (Scope 1), energy indirect (Scope 2), other indirect (Scope 3).

  • G4-EN18-d: Gases included in the calculation.
