Disclosure focus

Disclosure 302-5 requires an organization to report the reductions in energy requirements of products and services sold during the reporting period, expressed in joules or multiples.

The organization also reports the basis used to calculate the reductions, such as a base year or baseline, the rationale for choosing that basis, and the standards, methodologies, assumptions and calculation tools applied.

A percentage improvement or a reduction per functional unit can be provided as additional use-oriented information, but it does not replace the absolute reduction required by the disclosure. The organization should explain how per-unit improvements were aggregated across the relevant sold product or service population.

The calculation should clearly identify the product or service population, the functional unit, the baseline and current energy requirements, the number of products sold or services delivered, and the period represented by the reduction. Do not confuse reductions in the energy requirements of sold products and services with reductions in the organization’s own operational energy consumption under Disclosure 302-4.

Where applicable, use recognized industry use standards. Where different standards or methodologies apply, explain how they were selected and how the results were made comparable.

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

How to prepare it

Disclosure 302-5 requires an organization to report the reductions in energy requirements of products and services sold during the reporting period, expressed in joules or multiples.
Collect and reconcile the records for: Product or service population; Functional unit; Baseline energy requirement; Current energy requirement; Per-unit reduction; Absolute reduction; Reduction timeframe; Base year or baseline; Basis rationale; Industry standard; Method and assumptions; Conversion; Scope and limitations.
Apply Disclosure 302-5 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 302-5: Product or service population; Functional unit; Baseline energy requirement; Current energy requirement; Per-unit reduction; Absolute reduction; Reduction timeframe; Base year or baseline; Basis rationale; Industry standard; Method and assumptions; Conversion; Scope and limitations. 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.

Better request

Include scope, definitions, methods, assumptions, limitations, owners and approvals.

Draft your disclosure

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

Where applicable, use recognized industry use standards. Where different standards or methodologies apply, explain how they were selected and how the results were made comparable.

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 a percentage or per-unit improvement without the required absolute reduction.
Mixing sold-product energy requirements with the organisation's operational energy consumption.
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.
