Foco de la divulgación
Disclosure 301-2 requires an organization to report the percentage of recycled input materials used to manufacture its primary products and services.
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.
