This metric is based on the Global Reporting Initiative (GRI) G4 Guidelines. It covers one of the requirements of Indicator G4-EN6 - 'Reduction of energy consumption', wherein companies are encouraged to report the amount of reductions in energy consumption achieved as a direct result of conservation and efficiency initiatives, in joules or multiples.

An organization’s ability to use energy efficiently can be revealed by its reductions in energy consumption. Energy consumption has a direct effect on the environmental footprint of the organization, its operational costs, and exposure to fluctuations in energy supply and prices.


This metric is looking for reduction of reduction of energy consumption:

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-EN6, EN6 or reduction of energy consumption

  • 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 reduction in energy consumption - G4-EN6-a:

  • Calculate the energy saved by initiatives to reduce energy use and increase energy efficiency. Reductions in energy consumption that result from reduced production capacity or outsourcing should not be included in this Indicator.

  • Indicate whether energy savings are estimated, modeled, or sourced from direct measurements. If estimation or modeling is used, disclose the methods used.

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

  • G4-EN6-b: Report the types of energy included in the reductions: fuel, electricity, heating, cooling, and steam.

  • G4-EN6-c: Report the basis for calculating reductions in energy consumption such as base year or baseline and the rationale for choosing it.​

  • G4-EN6-d: Report standards, methodologies, and assumptions used.
