Disclosure focus

Disclosure 302-1 requires an organization to report energy consumption within entities that it owns or controls during the reporting period. The disclosure covers fuel from non-renewable and renewable sources; electricity, heating, cooling and steam consumed and sold; total energy consumption within the organization; the standards, methodologies, assumptions and calculation tools used; and the sources of conversion factors.

Fuel consumption must be reported separately for non-renewable and renewable sources and must include the fuel types used. Fuel and total energy consumption are reported in joules or multiples. Electricity, heating, cooling and steam consumed or sold are reported in joules, watt-hours or multiples.

When calculating total energy consumption, the organization must prevent double counting of self-generated energy. If fuel is used to generate electricity, heating, cooling or steam that is then consumed internally, the energy is counted once under fuel consumption. Electricity, heating, cooling and steam sold are disclosed separately and deducted when calculating total energy consumption.

The reporting boundary is not a discretionary selection of sites with available data. It covers energy consumed by entities owned or controlled by the organization. Where required information cannot be reported, the organization applies the relevant reason for omission in the GRI content index.

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 302-1 requires an organization to report energy consumption within entities that it owns or controls during the reporting period. The disclosure covers fuel from non-renewable and renewable sources; electricity, heating, cooling and steam consumed and sold; total energy consumption within the organization; the standards, methodologies, assumptions and calculation tools used; and the sources of conversion factors.
Collect and reconcile the records for: Organizational boundary; Non-renewable fuel consumption; Renewable fuel consumption; Purchased electricity; Purchased heating; Purchased cooling; Purchased steam; Self-generated energy; Electricity sold; Heating, cooling and steam sold; Double-counting control; Total energy consumption; Methodology; Conversion factors.
Apply Disclosure 302-1 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 302-1: Organizational boundary; Non-renewable fuel consumption; Renewable fuel consumption; Purchased electricity; Purchased heating; Purchased cooling; Purchased steam; Self-generated energy; Electricity sold; Heating, cooling and steam sold; Double-counting control; Total energy consumption; Methodology; Conversion factors. 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

Provide the reporting-period records and reconciliations for Disclosure 302-1: Organizational boundary; Non-renewable fuel consumption; Renewable fuel consumption; Purchased electricity; Purchased heating; Purchased cooling; Purchased steam; Self-generated energy; Electricity sold; Heating, cooling and steam sold; Double-counting control; Total energy consumption; Methodology; Conversion factors. 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

The reporting boundary is not a discretionary selection of sites with available data. It covers energy consumed by entities owned or controlled by the organization. Where required information cannot be reported, the organization applies the relevant reason for omission in the GRI content index.

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

Double counting fuel and the energy generated from that fuel for internal use.
Treating purchased renewable electricity as renewable fuel.
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.
