GRI Standards (Global Reporting Initiative) are the most widely adopted voluntary international sustainability reporting framework, used by over 14,000 organizations in 100+ countries. Developed and maintained by GRI since 1997, they are organized in three series: Universal Standards (GRI 1, 2, 3), Sector Standards (sector-specific) and Topic Standards (GRI 200 economic, GRI 300 environmental, GRI 400 social). TreeBlock natively supports all Topic Standards with bidirectional ESRS mapping.
What are GRI Standards and how are they structured?
GRI Standards are the global sustainability reporting framework focused on impact materiality: organizations report the impacts they generate on economy, environment and people. The 2021 revision (GRI Universal Standards 2021) reorganized the framework in a modular way and aligned it with integrated reporting principles and complementary standards (SASB, TCFD).
Current structure: Universal Standards (GRI 1 Foundation, GRI 2 General Disclosures, GRI 3 Material Topics), Sector Standards (GRI 11 Oil and Gas, GRI 12 Coal, GRI 13 Agriculture, GRI 14 Mining), Topic Standards (GRI 200 economic, GRI 300 environmental, GRI 400 social).
GRI vs ESRS: when to choose one or the other (or both)
CSRD imposes ESRS, GRI remains voluntary. International investors and NGOs are familiar with GRI; EU regulators require ESRS. EFRAG and GRI published in 2023 an interoperability statement mapping over 80 percent of GRI indicators to ESRS, so the same dataset can produce both reports.
How TreeBlock supports GRI reporting
TreeBlock automates GRI reporting in four phases: perimeter and material topics (GRI 3 four-step process), data collection via connectors, automatic indicator calculation (notably GRI 305 Emissions via integrated GHG Protocol engine), report generation with automatic GRI Content Index. The platform shows for each GRI indicator the corresponding ESRS one for seamless migration.
Frequently asked questions about GRI Standards
- What does GRI stand for?
- GRI stands for Global Reporting Initiative, the independent international organization founded in 1997 in Amsterdam that publishes and maintains the most widely adopted sustainability reporting standards globally.
- Are GRI Standards mandatory?
- No, GRI Standards are voluntary worldwide. In Italy they are not required by any regulation: mandatory CSRD reporting must follow ESRS. However many companies still use GRI because it is internationally recognized and interoperable with ESRS.
- What is the GRI Content Index?
- The GRI Content Index is the mandatory table that every GRI-compliant report must include, mapping each reported indicator to the page (or external link) where the information is disclosed. TreeBlock generates the GRI Content Index automatically.
- Can I switch from GRI to ESRS without losing historical data?
- Yes. Thanks to the EFRAG-GRI interoperability statement (2023), over 80 percent of GRI indicators map directly to ESRS. TreeBlock automates the bidirectional mapping.
