GRI·Explainer·Data and evidence
Stakeholder engagement is an evidence input to GRI materiality, not a vote that determines material topics. Existing HR, customer, supplier, community and grievance processes can be reused when they reach the relevant affected stakeholders, are meaningful and safe, generate traceable evidence, and are suitable for the impact being assessed.
Helps you decideWhich stakeholder evidence can be reused, where targeted engagement is necessary, and how the input affects the impact assessment.
