Disclosure focus
The organization must report hazardous and non-hazardous waste separately and break each total down by incineration with energy recovery, incineration without energy recovery, landfilling and other disposal operations. For every disposal operation, the organization must also report the amount disposed of onsite and offsite.
In the context of GRI 306, incineration with energy recovery is classified as a disposal operation. It must not be included in waste diverted from disposal under Disclosure 306-4.
Onsite means within the physical boundary or administrative control of the reporting organization. Offsite means outside its physical boundary and administrative control. Third-party involvement is a separate characteristic and must not be used as a substitute for onsite/offsite classification.
Do not classify a transfer, storage or intermediate treatment step as disposal. Confirm the documented final disposal operation and explain all operations reported under “other disposal operations”.
The organization must provide contextual information necessary to understand the data and the way it was compiled. It must exclude effluent unless national legislation requires its inclusion and use 1,000 kilograms as one metric ton.
The data should be reconciled with the total waste generated under Disclosure 306-3 and the waste diverted from disposal under Disclosure 306-4.
This LRA educational guidance supports disclosure preparation. For the exact requirements, always refer to the official Global Reporting Initiative source.
Prepare
What to collect before drafting
Tick each field as the evidence lands. Owners are the teams that usually hold the source files.
-
Working table 1: Waste composition
Waste / Operations / Sustainability ReportingPrepare and reconcile these columns: Waste composition; Waste directed to disposal, metric tons.
Evidence Approved source records, calculation files and review evidence supporting working table 1: waste composition.
Watch for The published response for working table 1: waste composition is incomplete or does not match the supporting records.
-
Working table 2: Waste type and disposal operation
Waste / Operations / Sustainability ReportingPrepare and reconcile these columns: Waste type and disposal operation; Onsite, t; Offsite, t; Total, t.
Evidence Approved source records, calculation files and review evidence supporting working table 2: waste type and disposal operation.
Watch for The published response for working table 2: waste type and disposal operation is incomplete or does not match the supporting records.
Before you start
- Disclosure 306-5 requires an organization to report the total weight of waste directed to disposal in metric tons and to break this total down by the composition of the waste.
- Apply Disclosure 306-5 when the related topic is material and the disclosure is applicable under the relevant GRI Standard.
- Have the supporting records and the final response been reconciled?
