Two Frameworks, One Goal
The Global Reporting Initiative (GRI) Standards and the European Sustainability Reporting Standards (ESRS) both seek comprehensive sustainability disclosure, but they approach it differently. Understanding their relationship is crucial for companies that may need to report under both.
Philosophical Alignment
GRI and EFRAG (which developed ESRS) have worked together to maximize interoperability. Both frameworks embrace the concept of impact materiality — reporting on how an organization affects people and the environment. However, ESRS adds financial materiality through its double materiality requirement, asking companies to also assess how sustainability issues affect the enterprise's value.
Structural Differences
GRI is organized around Universal Standards, Sector Standards, and Topic Standards, allowing companies to select applicable topics based on their materiality assessment. ESRS is structured around cross-cutting standards (ESRS 1 and ESRS 2) and topical standards covering environmental, social, and governance themes. While GRI offers flexibility in topic selection, ESRS requires companies to evaluate all topical standards through their double materiality assessment.
Key Areas of Divergence
- Value chain boundaries: ESRS has specific requirements for value chain reporting that may extend further than GRI expectations in some areas.
- Quantitative targets: ESRS places greater emphasis on forward-looking targets and transition plans, particularly for climate.
- Governance disclosures: ESRS requires detailed disclosure of sustainability governance structures, including board expertise and incentive mechanisms.
- Due diligence: ESRS explicitly links to the UN Guiding Principles and OECD Guidelines for due diligence processes.
Practical Approach to Dual Reporting
Organizations reporting under both frameworks should build a unified data collection system that captures the superset of requirements. Most data points required by GRI are also needed for ESRS, so a well-designed ESG data platform can serve both purposes simultaneously. Start with ESRS as the more prescriptive framework, then map any additional GRI requirements to fill gaps.
