Reduction of energy consumption

GRI 302-4 · mandatory · metrics + narrative

Disclosure 302-4 requires an organization to report the amount of reduction in energy consumption achieved as a direct result of conservation and efficiency initiatives, in joules or multiples.

Legal status

GRI 302: Energy 2016 remains applicable for reports or other materials published up to 31 December 2026. For reporting published on or after 1 January 2027, use the corresponding disclosure in GRI 103: Energy 2025.

Disclosure focus

The disclosure states the types of energy included — fuel, electricity, heating, cooling, steam, or all of these — the base year or baseline used and the rationale for selecting it, and the standards, methodologies, assumptions and calculation tools applied.

A reduction in total energy consumption does not automatically qualify. The organization must demonstrate a direct link between the reported reduction and an identified conservation or efficiency initiative. Reductions resulting from reduced production capacity or outsourcing must be excluded.

State whether each reduction was estimated, modelled or calculated using direct measurements. Where estimates or modelling were used, disclose the methods. Adjust or normalize the calculation for relevant changes in production, operating hours, occupancy, weather, product mix and organizational scope.

Reductions for different energy types can be presented separately or combined after conversion to a common joule-based unit. Prevent overlap and double counting between initiatives.

This LRA educational guidance supports disclosure preparation. For the exact requirements, always refer to the official Global Reporting Initiative source.

Before you start

  • Disclosure 302-4 requires an organization to report the amount of reduction in energy consumption achieved as a direct result of conservation and efficiency initiatives, in joules or multiples.
  • Apply Disclosure 302-4 when the related topic is material and this disclosure is relevant to the organisation's impacts, or when an applicable GRI Sector Standard identifies it for reporting.

How to prepare it

Disclosure 302-4 requires an organization to report the amount of reduction in energy consumption achieved as a direct result of conservation and efficiency initiatives, in joules or multiples.
Collect and reconcile the records for: Conservation or efficiency initiative; Eligible energy reduction; Types of energy; Base year or baseline; Rationale; Measurement basis; Estimation or modelling method; Normalization; Capacity and outsourcing exclusion; Units and conversion; Overlap control; Reporting scope and period.
Apply Disclosure 302-4 when the related topic is material and this disclosure is relevant to the organisation's impacts, or when an applicable GRI Sector Standard identifies it for reporting.
Draft the response using the defined terms shown in the disclosure focus; do not substitute broader internal labels.
Review the final wording against every requirement and the supporting governance or data records before sign-off.

Request the data

Request the disclosure evidence

Translate the disclosure into an internal business question — then adapt it to your organisation's own language.

Provide the reporting-period records and reconciliations for Disclosure 302-4: Conservation or efficiency initiative; Eligible energy reduction; Types of energy; Base year or baseline; Rationale; Measurement basis; Estimation or modelling method; Normalization; Capacity and outsourcing exclusion; Units and conversion; Overlap control; Reporting scope and period. Include scope, definitions, methods, assumptions, limitations, owners and approvals.

Use the organisation's own role and document names, but preserve the defined GRI terms and the scope described above.

Notes that turn data into a disclosure

LRA training templates — adapt them to your organisation, and check the official source before sign-off.

Method note

Reductions for different energy types can be presented separately or combined after conversion to a common joule-based unit. Prevent overlap and double counting between initiatives.

Context note

Keep mandatory Requirements, GRI recommendations and additional LRA preparation controls clearly distinguished. Use a GRI 1 reason for omission where an applicable requirement cannot be reported.

Evidence pack to prepare

Common reporting gaps

  • Reporting lower activity, reduced capacity or outsourcing as an efficiency reduction.
  • Reporting a reduction without a direct link to a conservation or efficiency initiative.
  • Using internal labels in place of the defined GRI terms.
  • Leaving a required preparation field unsupported by traceable evidence.
  • Treating GRI recommendations as mandatory requirements or mandatory requirements as optional.
  • Publishing estimates, exclusions or partial scope without methods, assumptions and the applicable reason for omission.
