Disclosure focus
This disclosure requires an organisation to report its gross other indirect (Scope 3) GHG emissions. These emissions are a consequence of the organisation’s activities but occur at sources that it does not own or control, excluding energy indirect Scope 2 emissions. They can arise across both the upstream and downstream value chain.
The disclosure requires the organisation to identify the Scope 3 categories and activities included in the calculation and to explain the calculation basis. Clearly documenting exclusions and data gaps is an LRA preparation recommendation that can help readers understand the coverage, but it is not an additional datapoint expressly required by Disclosure 305-3.
This LRA educational guidance supports disclosure preparation. For the exact requirements, always refer to the official Global Reporting Initiative source.

How to prepare it
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 305-3: Gross Scope 3 GHG emissions; Included Scope 3 categories and activities; Gases included; Biogenic CO2 emissions; Base year; Emission-factor and GWP sources; Calculation basis, assumptions and tools; Documented exclusions and data gaps. 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.

Method note
The disclosure requires the organisation to identify the Scope 3 categories and activities included in the calculation and to explain the calculation basis. Clearly documenting exclusions and data gaps is an LRA preparation recommendation that can help readers understand the coverage, but it is not an additional datapoint expressly required by Disclosure 305-3.
Context note
Keep mandatory GRI Requirements, GRI recommendations and additional LRA preparation controls clearly distinguished. Apply a GRI 1 reason for omission where required information cannot be reported.
