Waste diverted from disposal

GRI 306-4 · mandatory · metrics + narrative

Disclosure 306-4 requires an organization to report the total weight of waste diverted from disposal in metric tons and to break this total down by the composition of the waste.

Legal status

GRI 306: Waste 2020 remains the applicable GRI Topic Standard for waste reporting at the date of this review.

Disclosure focus

The organization must report hazardous and non-hazardous waste separately and break each total down by preparation for reuse, recycling and other recovery operations. For every recovery operation, the organization must also report the amount recovered onsite and offsite.

In the context of GRI 306, recovery operations do not include energy recovery. Incineration with energy recovery is treated as a disposal operation and is reported under Disclosure 306-5. Do not classify an intermediate treatment or transfer as recovery unless the documented final operation meets the definition of preparation for reuse, recycling or another recovery operation.

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 the onsite/offsite classification.

The organization must provide contextual information necessary to understand the data and how it was compiled. It must exclude effluent unless national legislation requires its inclusion and use 1,000 kilograms as one metric ton.

GRI also recommends reporting the total weight of waste prevented, together with the baseline and calculation methodology. Waste reductions caused only by lower production capacity should not be reported as waste prevention.

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

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 Reporting

    Prepare and reconcile these columns: Waste composition; Waste diverted from 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 recovery operation

    Waste / Operations / Sustainability Reporting

    Prepare and reconcile these columns: Waste type and recovery operation; Onsite, t; Offsite, t; Total, t.

    Evidence Approved source records, calculation files and review evidence supporting working table 2: waste type and recovery operation.

    Watch for The published response for working table 2: waste type and recovery operation is incomplete or does not match the supporting records.
