- **Sector Standardshigh-impact sector disclosures (e.g., Oil & Gas, Mining).
- **Topic Standardsspecific metrics (e.g., GRI 403 Occupational Health & Safety, GRI 308 Supplier Environmental Assessment). Compliance through "in accordance" reporting with mandatory GRI Content Index; no formal certification.
Why Organizations Use It
- Regulatory interoperability (CSRD, ESRS).
- Impact/risk management, supply chain due diligence.
- Stakeholder trust, benchmarking, investor alignment (with SASB).
- Strategic ESG integration, reputation enhancement.
