    • Sector Standards for high-impact industries like oil & gas, mining.
    • Topic Standards (e.g., GRI 403 Occupational Health & Safety, GRI 308 Supplier Environmental Assessment) with specific disclosures.
    • Core principles: accuracy, balance, verifiability; GRI Content Index for traceability; no certification, but 'in accordance' compliance.

    Why Organizations Use It

    Drives accountability, regulatory alignment (e.g., EU CSRD), risk management for HES impacts, stakeholder trust, and benchmarking. Enhances credibility, capital access, and operational efficiency.

    Implementation Overview
