    GRI Details

    What It Is

    GRI Standards are the world's most used sustainability reporting framework, developed by the Global Reporting Initiative. This modular system focuses on disclosing significant economic, environmental, and social impacts through an impact-centric materiality approach, distinguishing it from financial materiality standards.

    Key Components

    • Sector Standards for high-impact industries like oil & gas, mining.
    • Topic Standards (e.g., GRI 403 Occupational Health & Safety) with specific disclosures and metrics.
    • Core principles: accuracy, balance, verifiability; mandatory GRI Content Index for compliance.

    Why Organizations Use It

    Provides comparable data for stakeholders, aligns with regulations like EU CSRD, mitigates risks in HES and supply chains, enhances reputation, and supports interoperability with SASB/ISSB for investor needs.

    Implementation Overview

    Phased approach: materiality assessment, data systems build, management disclosures, content index. Applies to all sizes/industries globally; voluntary but assurance-ready; no formal certification.
