Disclosure focus
The percentage must be calculated by dividing the total recycled input materials used by the total input materials used and multiplying the result by 100. The denominator must use the total weight or volume of materials specified in Disclosure 301-1 and therefore cover the same production and packaging material population.
Apply the GRI definition of recycled input material. A recycled input material replaces virgin material, is purchased or obtained from internal or external sources, and is not a by-product or non-product output produced by the organization itself.
The numerator and denominator should cover the same reporting period, entities, sites, primary products and services, packaging scope and measurement basis. Where weight and volume measurements use different units, they can be converted to standardized units using documented conversion factors.
If estimation is required, report the estimation method used.
This LRA educational guidance supports disclosure preparation. For the exact requirements, always refer to the official Global Reporting Initiative source.

-
Recycled input materials used
Procurement / Supply ChainTotal weight or volume meeting the GRI definition of recycled input material.
Evidence Supplier declarations, recycled-content certificates, bills of materials and material specifications.
Watch for The published response for recycled input materials used is incomplete or does not match the supporting records.
-

Sustainability ReportingRecycled input materials divided by total input materials, multiplied by 100.
Evidence Calculation workbook and arithmetic reconciliation.
Watch for The published response for recycled input percentage is incomplete or does not match the supporting records.
-
Definition assessment
Sustainability / OperationsEvidence that included materials replace virgin inputs and are not the organization’s own by-products or NPO.
Evidence Classification register and supporting evidence.
Watch for The published response for definition assessment is incomplete or does not match the supporting records.
-
Mixed-content allocation
ProcurementRecycled and virgin portions of materials containing both types of content.
Evidence Supplier percentages, certificates and allocation calculations.
Watch for The published response for mixed-content allocation is incomplete or does not match the supporting records.
-
Measurement and conversion basis
OperationsWeight or volume units and any standardized-unit conversions.
Evidence Meter records, density factors and conversion workbook.
Watch for The published response for measurement and conversion basis is incomplete or does not match the supporting records.
-
Estimation method
Data owner / SustainabilitySource data, assumptions and method used where direct measurement was unavailable.
Evidence Estimation methodology and working papers.
Watch for The published response for estimation method is incomplete or does not match the supporting records.
-
Reporting scope
Sustainability ReportingEntities, sites, primary products, services and packaging included in numerator and denominator.
Evidence GRI 2-2 entity mapping and scope reconciliation.
Watch for The published response for reporting scope is incomplete or does not match the supporting records.
Before you start
- Disclosure 301-2 requires an organization to report the percentage of recycled input materials used to manufacture its primary products and services.
- Apply Disclosure 301-2 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.
- Have the supporting records and the final response been reconciled?
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 301-2: Total input materials used; Recycled input materials used; Recycled input percentage; Definition assessment; Mixed-content allocation; Measurement and conversion basis; Estimation method; Reporting scope. 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.

Evidence pack to prepare
Common reporting gaps
- Using purchases, recycled packaging or by-products outside the GRI recycled-input definition.
- Using a denominator that does not reconcile to Disclosure 301-1.
- 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.
