GRI Details
What It Is
GRI Standards, developed by the Global Reporting Initiative, are the world's leading modular framework for sustainability reporting. They provide a global common language for disclosing significant economic, environmental, and social impacts via an impact-centric materiality approach, requiring organizations to prioritize actual and potential effects on stakeholders.
Key Components
- Universal Standards (GRI 1: Foundation, GRI 2: General Disclosures, GRI 3: Material Topics): Baseline requirements, principles (accuracy, balance, verifiability), and materiality process.
- **Sector StandardsSector-specific likely material topics (e.g., Oil & Gas, Mining).
- **Topic StandardsSpecific metrics/disclosures (e.g., GRI 403 Occupational Health & Safety, GRI 308 Supplier Environmental Assessment). Compliance model uses mandatory GRI Content Index for traceability; no formal certification but supports assurance.
Why Organizations Use It
- Regulatory alignment (e.g., EU CSRD), investor demands, risk management.
- Builds stakeholder trust, enables benchmarking, enhances reputation.
- Drives governance, data architecture, supply chain due diligence.
Implementation Overview
Phased: materiality assessment, data systems, management disclosures, Content Index. Applies globally to all sizes/industries; voluntary with external assurance optional.
