Environmental Screening of New suppliers, GRI 308-1 (formerly G4-EN32)
What percentage of new suppliers were screened using environmental criteria?

About the data

This metric is based on the Global Reporting Initiative (GRI) Standard Guidelines.

In the context of the GRI Standards, the environmental dimension of sustainability concerns an organization’s impacts on living and non-living natural systems, including land, air, water and ecosystems. GRI 308 addresses the topic of supplier environmental assessment.

An organization might be involved with impacts either through its own activities or as a result of its business relationships with other parties.

Due diligence is expected of an organization in order to prevent andmitigate negative environmental impacts in the supply chain. These include impacts the organization either causes or contributes to, or that are directly linked to its activities, products, or services by its relationship with a supplier.

This disclosure informs stakeholders about the percentage of suppliers selected or contracted subject due diligence processes for environmental impacts.

An organization is expected to initiate due diligence as early as possible in the development of a new relationship with a supplier. Impacts may be prevented or mitigated at the stage of structuring contracts or other agreements, as well as via ongoing collaboration with suppliers.

*In 2018, the GRI G4 Sustainability Reporting Guidelines were superseded by the GRI Sustainability Reporting Standards (GRI standards). For this metric, the code G4-EN32 is used in company reporting prior to 2018, and the new GRI 308-1 code is used in reporting from 2018 onwards. The methodology for the former G4 standard for this metric can be found here.

For WikiRate researchers:

  • Always check the metric question and methodology for the unit of measure or currency - researchers may need to carry out calculations or conversions before entering the final metric value

  • Add comments documenting exactly where within the source you found the information (page number) and include details of simple or complex calculations or conversions made to determine the metric value.

Select the 'Unknown' answer box if the company has not published the data.
