GRI Standards ↔ IFRS
How impact materiality and investor materiality can coexist in a single reporting workflow.
A communications director at a consumer goods company in São Paulo held two reports. One was for investors: IFRS S1 and S2, financial materiality, enterprise value. The other was for stakeholders: GRI Standards, impact materiality, multi-stakeholder. The same company, the same data, two different audiences. The investor report focused on climate risk and financial exposure. The stakeholder report focused on community impact and supply chain labor. Both were true. Neither was complete without the other.
The ISSB and GRI published joint interoperability guidance in May 2024. It confirmed that companies can report under both frameworks without duplication. The overlap is in the data: greenhouse gas emissions, water usage, workforce demographics, governance structure. The difference is in the lens: IFRS asks "what affects enterprise value?" GRI asks "what affects the world?" Both questions matter. Both answers are needed.
Under IFRS S1 §54–59, entities may refer to other standard-setting bodies for guidance. The GRI-IFRS interoperability guidance provides that reference: GRI 302 (energy) maps to IFRS S2 energy metrics, GRI 401 (employment) maps to IFRS S1 workforce disclosures. The communications director in São Paulo no longer prepares two reports from scratch. She prepares one dataset and presents it through two lenses. The investor sees financial materiality. The stakeholder sees impact. Both see the truth.
GRI and IFRS measure different things — impact materiality for multi-stakeholder reporting, financial materiality for investors — but the data underlying both disclosures is often the same.
In Plain Language
GRI and IFRS measure different things — impact materiality for multi-stakeholder reporting, financial materiality for investors. The May 2024 ISSB-GRI joint guidance confirms that companies can report under both frameworks when disclosures share the same underlying data.
- GRI and IFRS measure different things — impact materiality for multi-stakeholder reporting, financial materiality for investors — but the data underlying both disclosures is often the same.
- Joint ISSB-GRI interoperability guidance confirms that companies can report under both frameworks without duplication when disclosures share the same underlying data.
- The practical test is whether a company can present the same dataset through two lenses — financial materiality for investors, impact materiality for stakeholders — without contradiction.
