Connected Information & Framework Alignment
How IFRS S1 and S2 connect sustainability disclosure to financial statements and align with other reporting systems.
In 1972, a Norwegian fisheries scientist named Odd Nakken solved a problem that would take the accounting profession another fifty years to notice: how do you measure something whose impacts flow in both directions? Nakken was studying salmon migration in the North Atlantic. He found that the fish's health depended on ocean temperature, but the ocean temperature was also affected by the fish — their movement patterns, their spawning cycles, their interaction with currents. You couldn't measure the fish without measuring the water, and you couldn't measure the water without measuring the fish.
That is the logic behind IFRS S1's "connected information" requirement (§21–24, §64). Sustainability disclosures cannot be isolated from financial statements. If a climate risk reduces an asset's value, that connection must be disclosed. If a carbon tax changes the economics of a business line, the financial impact must be quantified. The sustainability report is not a separate document — it is part of the annual report.
The ISSB designed IFRS S1 and S2 to interoperate with other frameworks, not replace them. The May 2024 interoperability guidance between the ISSB and EFRAG confirmed that companies reporting under ESRS can claim compliance with IFRS S1 and S2 for climate disclosures. GRI and the ISSB published joint guidance on how impact materiality (GRI) and financial materiality (ISSB) can coexist. The TCFD recommendations were fully incorporated into IFRS S2 when the FSB transferred monitoring to the ISSB in 2024. Nakken's salmon — fish and water, inseparable — is the model. Sustainability and finance are the same system.
Connected information turns isolated disclosures into a system — framework alignment begins when standards share an evidence base.
In Plain Language
IFRS S1 and S2 were designed to interoperate — with each other, with the TCFD, and with other global frameworks. S1 requires connected information with financial statements (§21–24). S2 incorporates the TCFD's four-pillar structure. The May 2024 ISSB-EFRAG and ISSB-GRI interoperability guidance confirms that overlapping disclosures can satisfy multiple frameworks. These four requirements explain how standards that were developed separately now work together.

Technical Requirements
- Financial statement linkage — IFRS S1 §21–24: Sustainability disclosures must be connected to the financial statements — explaining how sustainability risks and opportunities affect financial position, performance, and cash flows.
- TCFD incorporation — IFRS S2: The Financial Stability Board transferred TCFD monitoring to the ISSB in 2024. IFRS S2's four-pillar structure — governance, strategy, risk, metrics — is the TCFD architecture.
- GRI and ESRS interoperability — May 2024 ISSB-EFRAG and ISSB-GRI guidance: Companies can report under multiple frameworks when disclosures share the same underlying data — climate governance under IFRS S2 can satisfy ESRS E1 requirements.
- Duplicate disclosure reduction — IFRS S1 §54–59: Entities may refer to other standard-setting bodies. The interoperability guidance eliminates the need to report the same information twice when frameworks overlap.
