General Requirements for Disclosure of Sustainability-related Financial Information
Establishes the general requirements for sustainability-related financial disclosures, including the four content pillars, materiality, and connected information.
1
Conceptual Framework Linkage
Extending decision-usefulness beyond the financial statements
The Conceptual Framework's core objective – providing information USEFUL to existing/potential investors, lenders, and creditors for resource allocation decisions – increasingly requires understanding risks and opportunities that traditional financial statements do NOT capture directly, particularly those arising from sustainability matters (climate, nature, social factors) affecting an entity's ENTERPRISE VALUE over the short, medium, and long term. IFRS S1 extends the Framework's decision-usefulness objective into this new disclosure domain.
HOW IFRS S1 MAPS TO THE FRAMEWORK
Relevance – sustainability-related risks/opportunities can materially affect an entity's future cash flows, and thus its enterprise value, even where not yet reflected in current financial statement figures Faithful representation – IFRS S1 requires disclosure calibrated to genuine materiality, avoiding both omission of decision-useful information and "greenwashing" via unsubstantiated claims Comparability – a single global baseline standard (rather than a patchwork of voluntary frameworks) aims to make sustainability disclosures genuinely comparable across entities and jurisdictions, mirroring IFRS's own historical rationale for global financial reporting convergence
IFRS S1 was issued by the newly created International Sustainability Standards Board (ISSB), a SISTER board to the IASB under the same IFRS Foundation – reflecting the Foundation's expansion beyond financial reporting into sustainability disclosure as a formally connected but DISTINCT reporting domain.
The "enterprise value" focus, at a glance
IFRS S1 centres disclosure on information useful for assessing ENTERPRISE VALUE – not environmental/social impact for its own sake, but financially material effects on the reporting entity itself.
ConceptIFRS S1's framing
Focus"Financial materiality" – effects ON the entity's value, cash flows, cost of capital
Distinct from"Double materiality" frameworks (e.g. EU ESRS) which ALSO require disclosure of the entity's impact ON society/environment
This SINGLE (investor-focused) materiality lens is a KEY distinguishing feature of the ISSB's approach relative to broader multi-stakeholder sustainability reporting frameworks.

Scope & Definitions
What IFRS S1 covers
IFRS S1 requires an entity to disclose information about ALL sustainability-related risks and opportunities that could REASONABLY BE EXPECTED to affect the entity's cash flows, access to finance, or cost of capital over the short, medium, or long term – establishing the GENERAL, overarching disclosure framework that topic-specific standards (like IFRS S2) build upon.
IFRS S1 is designed to be APPLIED ALONGSIDE topic-specific standards such as IFRS S2 – it supplies the general architecture (materiality, content pillars, connected information) within which topic-specific disclosures are made.
Key definitions you must know
Sustainability-related risks and opportunities
Risks and opportunities that could reasonably be expected to affect an entity's enterprise value, arising from sustainability matters.
Enterprise value
The value of an entity's business as a whole, encompassing the value attributable to equity and other capital providers – the central reference point for IFRS S1's materiality assessment.
General purpose sustainability-related financial disclosures
Disclosures designed to meet the common information needs of primary users, mirroring the terminology of general purpose financial statements.

Sustainability-related Risks and Opportunities
A time-horizon-explicit requirement
An entity discloses information about sustainability-related risks/opportunities across THREE time horizons – SHORT, MEDIUM, and LONG term – as DEFINED by the entity itself, and CONSISTENT with the horizons used for related capital allocation and strategic planning decisions, and with horizons commonly used by the entity's INDUSTRY.
Requiring EXPLICIT time horizon disclosure directly serves the Framework's relevance objective – sustainability risks (e.g. climate physical risk) often materialise over MUCH longer horizons than traditional financial statement disclosures typically address, and IFRS S1 ensures this longer-term view is not lost.

The Four Content Pillars – TCFD Alignment
Governance, Strategy, Risk Management, Metrics and Targets
IFRS S1 organises disclosure around FOUR core content areas, directly built on the widely adopted TCFD (Task Force on Climate-related Financial Disclosures) recommendations:
Governance – the governance processes/controls/procedures used to MONITOR and MANAGE sustainability-related risks and opportunities Strategy – the approach to managing sustainability-related risks/opportunities, and their ACTUAL and POTENTIAL effects on the entity's business model, strategy, and financial position Risk management – the processes used to IDENTIFY, ASSESS, PRIORITISE, and MONITOR sustainability-related risks (and opportunities) Metrics and targets – the entity's PERFORMANCE in relation to sustainability-related risks/opportunities, including progress toward any targets set
Example 1: Applying the four pillars to a supply chain risk
A manufacturer identifies a material risk that a key raw material's future availability may be disrupted by water scarcity in its primary sourcing region.
Governance: disclose which board committee oversees supply chain risk monitoring.
Strategy: disclose how this risk could affect production costs/continuity, and any diversification strategy adopted.
Risk management: disclose the process used to identify and monitor water scarcity risk across the supply chain.
Metrics and targets: disclose any specific water-usage-related KPIs or supplier diversification targets, and progress against them.
Strategy: disclose how this risk could affect production costs/continuity, and any diversification strategy adopted.
Risk management: disclose the process used to identify and monitor water scarcity risk across the supply chain.
Metrics and targets: disclose any specific water-usage-related KPIs or supplier diversification targets, and progress against them.

Materiality Under IFRS S1
The same materiality concept as IAS 1, applied to sustainability information
Sustainability-related financial information is MATERIAL if omitting, misstating, or obscuring it could REASONABLY BE EXPECTED to influence decisions that primary users of general purpose financial reports make on the basis of those reports – an EXPLICIT, DELIBERATE alignment with the SAME materiality concept applied in IAS 1 and the Conceptual Framework.
Example 2: A materiality assessment
A technology company with minimal physical operations assesses whether extensive water usage disclosures (typically material for manufacturing/agriculture) are material to ITS OWN business.
Given the company's minimal water usage and negligible exposure to water-related risk, extensive water usage metrics are UNLIKELY to be material – IFRS S1's materiality principle allows (indeed requires) tailoring disclosure to what is GENUINELY decision-useful for the SPECIFIC entity, rather than mechanically reporting a fixed universal checklist regardless of relevance.
6
Connected Information
Linking sustainability disclosures to the financial statements
IFRS S1 requires an entity to provide "CONNECTED INFORMATION" – explaining the CONNECTIONS between sustainability-related risks/opportunities and information in the general purpose FINANCIAL STATEMENTS (e.g. how a climate transition risk might affect asset impairment assumptions under IAS 36, or a provision under IAS 37) – ensuring sustainability disclosures are NOT siloed from, but genuinely INTEGRATED with, the entity's financial reporting.
7
Sources of Guidance – SASB & Others
Building on, not replacing, existing frameworks
Where an entity has NOT identified a specific IFRS Sustainability Disclosure Standard covering a particular sustainability matter, IFRS S1 directs it to consider the SASB (Sustainability Accounting Standards Board) Standards, and MAY consider other sources such as the CDSB Framework, or GRI/ESRS disclosures, as appropriate – reflecting the ISSB's approach of CONSOLIDATING and building upon PRE-EXISTING voluntary sustainability reporting frameworks rather than starting from scratch.
8
Location and Timing of Reporting
Aligned with the financial statements
General purpose sustainability-related financial disclosures are required to be reported AS PART OF an entity's general purpose financial reporting, and at the SAME TIME as the related financial statements – ensuring users receive an INTEGRATED, timely picture rather than a separately timed sustainability report published months later.
9
Disclosure Requirements
Required disclosures under IFRS S1
Governance processes/controls used to monitor and manage sustainability-related risks/opportunities Strategy for managing material sustainability-related risks/opportunities, and their effect on the business model Processes used to identify, assess, prioritise, and monitor sustainability-related risks/opportunities Metrics and targets used to measure/monitor performance, including progress toward targets Connected information linking sustainability disclosures to the financial statements
10
Critical Judgments & Estimates
Where management judgement matters most
SIGNIFICANT JUDGEMENTS
Determining which sustainability-related risks/opportunities are material to the specific entity Selecting appropriate short/medium/long-term time horizons Identifying connections between sustainability disclosures and financial statement line items
SIGNIFICANT ESTIMATES
Forward-looking estimates of the financial effect of sustainability-related risks/opportunities Metrics quantifying performance against sustainability-related targets
Because IFRS S1 is a genuinely NEW area of reporting for most entities, developing the underlying data collection systems and governance processes to support these disclosures represents a SIGNIFICANT implementation undertaking, often more challenging than the disclosure drafting itself.

IFRS S1 vs Other Frameworks (ESRS/GRI)
Comparison – IFRS S1 vs the EU's ESRS and the GRI Standards
FeatureIFRS S1 (ISSB)EU ESRS / GRI
Materiality conceptSINGLE (financial) materiality – effects ON enterprise valueESRS/GRI generally apply "DOUBLE materiality" – ALSO requiring disclosure of the entity's impact ON people/environment
Primary user focusInvestors, lenders, creditors – mirroring IFRS financial reporting's own user baseBroader MULTI-STAKEHOLDER audience, including employees, communities, NGOs
Structural frameworkTCFD-aligned four pillars (governance, strategy, risk management, metrics/targets)Broadly similar structure, though ESRS/GRI have their OWN distinct topical standards and reporting requirements
Many jurisdictions and companies must navigate BOTH ISSB and EU/GRI-style frameworks SIMULTANEOUSLY – the single vs double materiality distinction is the MOST consequential conceptual difference determining what must ultimately be disclosed under each regime.
