IFRS S1 is the global baseline standard for disclosing sustainability-related financial information in a way that matters to investors, lenders, and other capital providers. It tells companies what sustainability-related risks and opportunities they should report when those issues could affect cash flows, access to finance, or cost of capital over the short, medium, or long term. If you want to understand sustainability reporting as serious financial reporting rather than broad ESG storytelling, IFRS S1 is a core standard to learn.

1. Term Overview

• Official Term: IFRS S1
• Common Synonyms: IFRS Sustainability Disclosure Standard S1, ISSB IFRS S1, General Requirements for Disclosure of Sustainability-related Financial Information
• Alternate Spellings / Variants: IFRS-S1
• Domain / Subdomain: Finance | Accounting Standards and Frameworks | Government Policy, Regulation, and Standards
• One-line definition: IFRS S1 is the ISSB standard that sets the general requirements for disclosing material sustainability-related financial information.
• Plain-English definition: IFRS S1 tells a company how to report sustainability issues that could materially affect its business, finances, and long-term prospects.
• Why this term matters:
• It brings sustainability reporting closer to mainstream financial reporting.
• It helps investors compare companies more consistently.
• It reduces vague, marketing-style ESG disclosures.
• It creates a global baseline that jurisdictions can adopt or build upon.

2. Core Meaning

IFRS S1 is a reporting standard issued by the International Sustainability Standards Board (ISSB) under the IFRS Foundation. It is designed to make sustainability disclosures useful for financial decision-making.

What it is

It is a general disclosure standard for sustainability-related financial information. Think of it as the umbrella standard for investor-focused sustainability reporting.

Why it exists

Before IFRS S1, sustainability reporting was often fragmented:

• one company used TCFD wording,
• another used SASB metrics,
• another used GRI-style impact reporting,
• many used mixed, inconsistent approaches.

This made comparison difficult for investors, analysts, lenders, and regulators.

What problem it solves

IFRS S1 addresses four major problems:

1. Inconsistency in sustainability reporting
2. Poor comparability across firms and industries
3. Weak linkage between sustainability topics and financial performance
4. Boilerplate disclosures that say little about real business risk

Who uses it

• Listed companies
• Large private companies with external capital providers
• Finance teams and sustainability teams
• Boards and audit committees
• Investors and analysts
• Lenders and credit committees
• Regulators and standard-setters
• Assurance providers

Where it appears in practice

IFRS S1 appears in:

• annual reports,
• management discussion sections,
• sustainability-related sections of general purpose financial reports,
• investor communications that align with formal reporting,
• disclosure control and governance processes.

3. Detailed Definition

Formal definition

IFRS S1 sets out the general requirements for an entity to disclose material information about 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.

Technical definition

Technically, IFRS S1 is a principles-based disclosure standard that requires an entity to provide decision-useful sustainability-related financial information for the primary users of general purpose financial reports, typically investors, lenders, and other creditors.

Key technical ideas include:

• materiality
• connected information
• fair presentation
• comparability
• entity-specific disclosure
• short-, medium-, and long-term time horizons
• linkage to strategy, governance, risk management, metrics, and targets

Operational definition

Operationally, IFRS S1 is the rulebook management uses to answer questions such as:

• Which sustainability topics are financially material?
• What should be disclosed to investors?
• How should sustainability information connect with the financial statements?
• What metrics, targets, assumptions, and governance details should be reported?

Context-specific definitions

In corporate reporting

IFRS S1 is the framework for producing investor-focused sustainability disclosures in annual reporting.

In capital markets

It is a comparability tool that helps analysts and investors assess how sustainability issues may influence valuation, risk, and financing conditions.

In regulation and policy

It functions as a global baseline standard that jurisdictions may adopt, adapt, endorse, or reference in local disclosure regimes.

In accounting education

It is part of the growing bridge between traditional financial reporting and sustainability-related risk disclosure.

4. Etymology / Origin / Historical Background

Origin of the term

• IFRS refers to the IFRS Foundation reporting ecosystem.
• The “S” in S1 denotes Sustainability.
• S1 indicates the first IFRS Sustainability Disclosure Standard.

This naming is important because IFRS S1 is not an IFRS Accounting Standard like IFRS 15 or IFRS 16. It belongs to a separate sustainability disclosure series under the ISSB.

Historical development

IFRS S1 emerged from years of market demand for better sustainability disclosure. Investors wanted clearer information about how climate, resource constraints, labor issues, supply-chain disruption, regulation, and other sustainability matters affect company value.

Earlier frameworks influenced its development:

• TCFD recommendations
• SASB industry standards
• CDSB reporting approaches
• integrated reporting thinking

How usage changed over time

Earlier sustainability reporting was often broad, stakeholder-oriented, and sometimes weakly linked to financial consequences. IFRS S1 shifted the focus toward investor-useful, financially connected disclosure.

Important milestones

Milestone	Significance
Growing use of TCFD and SASB in the late 2010s	Built demand for more structured investor-focused sustainability reporting
Creation of the ISSB by the IFRS Foundation	Established a global standard-setting body for sustainability disclosures
Consolidation of key reporting initiatives into the IFRS Foundation ecosystem	Reduced fragmentation and brought market practices closer together
Exposure drafts for S1 and S2	Allowed market feedback on proposed sustainability disclosure architecture
Issue of IFRS S1 in 2023	Created the formal baseline standard for general sustainability-related financial disclosures
Effective date from annual periods beginning on or after 1 January 2024	Enabled first-cycle reporting by adopters
2024 onward jurisdictional adoption and alignment efforts	Made IFRS S1 increasingly relevant in cross-border reporting

Important: Adoption is jurisdiction-specific. A company should always verify whether IFRS S1 is mandatory, permitted, endorsed, or only voluntary in its reporting environment.

5. Conceptual Breakdown

5.1 Objective and Scope

Meaning: IFRS S1 covers sustainability-related risks and opportunities that may affect enterprise prospects.

Role: It defines what the standard is trying to achieve: useful information for capital providers.

Interaction with other components: Scope interacts directly with materiality, time horizon, and disclosure content.

Practical importance: If a topic cannot reasonably affect cash flows, access to finance, or cost of capital, it may fall outside IFRS S1 materiality even if it is socially important.

5.2 Materiality

Meaning: Information is material if omitting, misstating, or obscuring it could reasonably influence the decisions of primary users.

Role: Materiality is the filter that decides what must be disclosed.

Interaction with other components: Materiality determines which risks, opportunities, metrics, targets, and narrative explanations become part of the report.

Practical importance: IFRS S1 does not ask companies to report every sustainability topic. It asks them to report the ones that matter financially to users of general purpose financial reports.

5.3 Time Horizons: Short, Medium, and Long Term

Meaning: Companies must think beyond immediate annual effects.

Role: Sustainability risks often unfold over different timeframes.

Interaction with other components: Time horizon affects strategy, scenario analysis, resilience assessment, targets, and capital planning.

Practical importance: A flood risk may be short-term, a water scarcity issue medium-term, and transition-to-low-carbon technology long-term.

5.4 The Four Core Content Pillars

IFRS S1 uses a structure closely aligned with the familiar TCFD architecture.

Governance

• Meaning: Who oversees sustainability-related risks and opportunities
• Role: Shows accountability at board and management level
• Interaction: Supports credible strategy, risk management, and metrics
• Practical importance: Investors want to know whether oversight is real or symbolic

Strategy

• Meaning: How sustainability issues affect business model, value chain, strategic decisions, and resilience
• Role: Explains business consequences
• Interaction: Connects sustainability topics to financial outcomes
• Practical importance: This is often the most decision-useful part for investors

Risk Management

• Meaning: How the entity identifies, assesses, prioritizes, and monitors sustainability-related risks and opportunities
• Role: Shows process discipline
• Interaction: Links governance to execution
• Practical importance: Good governance without risk processes is weak reporting

Metrics and Targets

• Meaning: Quantitative or qualitative indicators used to monitor performance and progress
• Role: Makes disclosures measurable
• Interaction: Supports comparability and target tracking
• Practical importance: Without metrics, disclosures can become vague

5.5 Connected Information

Meaning: Sustainability disclosures should connect with the financial statements and other related disclosures.

Role: Prevents contradictions and isolated reporting.

Interaction: Governance, strategy, risks, metrics, and financial impacts should tell one coherent story.

Practical importance: If a company says climate risk is material in the sustainability section but impairment assumptions ignore it, users will question credibility.

5.6 Reporting Entity Boundary and Value Chain

Meaning: The reporting entity generally aligns with the financial reporting entity, but disclosures may require information from the value chain.

Role: Expands reporting beyond only owned operations where necessary.

Interaction: Strategy, metrics, and risk analysis may require upstream supplier and downstream customer information.

Practical importance: A retailer’s labor risk or a bank’s financed emissions exposure may sit heavily in the value chain, not just inside head office operations.

5.7 Metrics, Targets, Estimates, and Uncertainty

Meaning: Companies disclose how they measure relevant sustainability-related matters, including progress against targets where applicable.

Role: Turns narrative into evidence.

Interaction: Metrics should support risk management and strategic claims.

Practical importance: Estimates are often necessary. Companies should explain assumptions and uncertainty rather than pretend precision they do not have.

5.8 Location, Timing, Comparatives, and Consistency

Meaning: Sustainability-related financial disclosures should be part of general purpose financial reporting and generally align in timing with financial statements.

Role: Treats sustainability disclosure as serious reporting, not an optional brochure.

Interaction: Timing and comparatives support investor analysis over time.

Practical importance: Delayed or separately issued disclosures can reduce usefulness unless local rules provide transitional relief.

7. Where It Is Used

Accounting and corporate reporting

This is the main home of IFRS S1. It is used in annual reporting and other investor-facing general purpose financial reporting.

Finance and capital markets

Investors, lenders, and rating analysts use IFRS S1-style disclosures to assess:

• business resilience,
• financing risk,
• earnings stability,
• valuation assumptions,
• long-term capital allocation quality.

Stock market context

Listed companies are the most visible users because public market investors demand comparable information. Exchanges or regulators may also reference ISSB-style disclosures.

Policy and regulation

Governments and regulators may:

• adopt IFRS S1 directly,
• use it as the basis of local standards,
• align local requirements with it,
• reference it in consultation papers or sustainability roadmap policies.

Business operations

Internally, IFRS S1 affects:

• risk registers,
• board reporting,
• procurement and supply-chain mapping,
• capital expenditure prioritization,
• resilience planning.

Banking and lending

Banks and lenders use IFRS S1-type information to evaluate borrower resilience, covenant risk, refinancing risk, and sector transition exposure.

Valuation and investing

Analysts use it to test assumptions about:

• revenue durability,
• cost inflation,
• capex needs,
• terminal value assumptions,
• cost of capital.

Reporting and disclosures

IFRS S1 matters most where sustainability claims must be:

• governed,
• documented,
• connected to financial information,
• reviewed internally,
• possibly assured externally.

Analytics and research

Sell-side analysts, ESG research teams, and credit researchers use IFRS S1 disclosures to improve company comparisons.

Economics

IFRS S1 is not mainly a macroeconomics term. Its relevance to economics is indirect, through capital allocation, market efficiency, and regulatory policy.

8. Use Cases

Use Case Title	Who Is Using It	Objective	How IFRS S1 Is Applied	Expected Outcome	Risks / Limitations
Annual report sustainability section	Listed company finance and sustainability teams	Produce investor-grade disclosure	Material topics are identified and disclosed under governance, strategy, risk management, and metrics/targets	More credible annual reporting	Boilerplate language if teams lack data
Board oversight reporting	Board, audit committee, risk committee	Improve governance and accountability	Management maps material issues to board oversight and decision rights	Better governance visibility	Superficial governance statements without evidence
Debt financing communication	Treasury team and lenders	Support financing discussions	Disclosures explain resilience, transition planning, and risk management	Better lender confidence and pricing conversations	Weak quantification can reduce credibility
Investor comparison and engagement	Asset managers and analysts	Compare companies consistently	Analysts use S1-aligned disclosures to compare strategic resilience	Better investment decisions	Cross-company comparability still depends on disclosure quality
M&A due diligence	Corporate development teams	Identify hidden sustainability-related financial risks	Buyer reviews target’s material sustainability exposures and disclosure readiness	Better pricing and risk adjustment	Target data may be incomplete
Multi-framework reporting alignment	Multinational companies	Reduce duplication across frameworks	IFRS S1 becomes the investor-focused baseline, then mapped to local frameworks	More efficient reporting architecture	Mapping can be complex across jurisdictions
Value-chain risk management	Procurement and operations leaders	Understand upstream and downstream exposures	Company discloses supplier concentration, resource dependency, and resilience issues	Better continuity planning	Value-chain data can be difficult to collect

9. Real-World Scenarios

A. Beginner scenario

• Background: A mid-sized listed company already publishes a glossy ESG brochure.
• Problem: Investors say the report is attractive but not useful because it does not explain financial impact.
• Application of the term: The company applies IFRS S1 to identify which sustainability issues could affect cash flows and financing.
• Decision taken: It narrows disclosure to material topics such as energy cost exposure, labor turnover, and supplier concentration.
• Result: The next report is shorter, more specific, and more useful to investors.
• Lesson learned: IFRS S1 is about decision-useful disclosure, not reporting everything.

B. Business scenario

• Background: A beverage company operates plants in water-stressed regions.
• Problem: Water availability could disrupt production and increase capex requirements.
• Application of the term: Management evaluates water scarcity as a sustainability-related risk with near-term and medium-term financial effects.
• Decision taken: It discloses governance oversight, contingency capex, production risk, and water efficiency targets.
• Result: Stakeholders understand both operational and financing implications.
• Lesson learned: IFRS S1 works best when sustainability risk is linked directly to business model and financial planning.

C. Investor / market scenario

• Background: An asset manager compares two cement companies.
• Problem: Both claim strong sustainability performance, but one provides detailed S1-style disclosure and the other uses vague language.
• Application of the term: The investor uses IFRS S1 categories to assess governance, strategy, transition exposure, and metrics quality.
• Decision taken: The investor gives the better-disclosing company a lower governance-risk discount.
• Result: Capital allocation becomes more disciplined.
• Lesson learned: Better disclosure can improve market confidence, even before performance fully improves.

D. Policy / government / regulatory scenario

• Background: A jurisdiction wants a sustainability disclosure baseline for listed entities.
• Problem: It needs internationally understandable disclosures without creating an entirely new system from scratch.
• Application of the term: Policymakers review IFRS S1 as a baseline and consider local additions.
• Decision taken: The jurisdiction consults on adopting or aligning with ISSB-based standards.
• Result: Market participants get more consistent reporting expectations.
• Lesson learned: IFRS S1 is valuable as a global baseline, but local law determines final compliance obligations.

E. Advanced professional scenario

• Background: A multinational group reports in multiple jurisdictions, including one using EU-style standards and another using a more investor-focused baseline.
• Problem: The company faces duplicated data requests and inconsistent internal definitions.
• Application of the term: The group uses IFRS S1 as its investor-focused core architecture and maps other frameworks onto it.
• Decision taken: It builds one data model with jurisdiction-specific overlays.
• Result: Reporting becomes more controlled and efficient.
• Lesson learned: IFRS S1 can serve as the backbone of a broader reporting system, but interoperability planning is essential.

10. Worked Examples

Simple conceptual example

A clothing company sources heavily from one region. Labor unrest and supplier shutdowns could delay inventory. Under IFRS S1, the company asks:

1. Is this a sustainability-related risk?
2. Could it affect sales, costs, or financing?
3. Is it material to investors?

If the answer is yes, the company should disclose:

• governance over supply-chain resilience,
• strategy for diversification,
• risk management process for supplier screening,
• metrics such as supplier concentration and disruption days.

Practical business example

A bank has large lending exposure to sectors facing transition risk. It applies IFRS S1 by disclosing:

• board oversight of sustainability-related credit risk,
• strategic implications for lending portfolios,
• risk assessment processes for borrowers,
• portfolio metrics and internal targets.

This helps users understand not only environmental themes, but also loan quality, capital deployment, and earnings resilience.

Numerical example

Scenario: A beverage company evaluates water scarcity at one major plant.

• Total company revenue: 500 million
• Revenue from water-stressed plant: 200 million
• Expected production loss if restrictions occur: 5%
• EBIT margin on that plant’s output: 18%
• Potential additional borrowing spread if no mitigation plan exists: 0.40%
• Debt potentially affected: 120 million
• Estimated mitigation capex: 7 million

Step 1: Revenue at risk

Revenue at risk = Revenue from exposed plant × expected production loss

Revenue at risk = 200 million × 5% = 10 million

Step 2: EBIT at risk

EBIT at risk = Revenue at risk × EBIT margin

EBIT at risk = 10 million × 18% = 1.8 million

Step 3: Additional annual interest cost

Additional interest cost = Affected debt × spread increase

Additional interest cost = 120 million × 0.40% = 0.48 million

Step 4: Interpret the result

Near-term annual financial effect identified:

• EBIT at risk: 1.8 million
• Additional finance cost: 0.48 million
• Mitigation capex need: 7 million

Conclusion

The company has a potentially material sustainability-related financial exposure. Under IFRS S1, it should consider disclosing:

• governance of water risk,
• operational strategy,
• risk management process,
• metrics and targets,
• current and anticipated financial effects.

Important: These calculations are management analysis tools. IFRS S1 does not prescribe this exact formula.

Advanced example

A multinational manufacturer must report to global investors while also meeting local sustainability reporting requirements. It uses IFRS S1 as the base framework:

1. Identify material sustainability-related risks and opportunities
2. Organize them under the four pillars
3. Link them to financial planning and assumptions
4. Map the same underlying data to local reporting frameworks

The benefit is consistency. The challenge is ensuring local frameworks may require additional disclosures beyond IFRS S1.

11. Formula / Model / Methodology

There is no single mandatory formula inside IFRS S1 like a ratio or accounting equation. IFRS S1 is a disclosure framework and methodology standard, not a mathematical formula standard.

The practical methodology

Step	What You Do	Why It Matters	Typical Output	Common Mistake
1	Define reporting entity and reporting period	Establish scope and timing	Reporting boundary	Boundary does not match financial reporting entity
2	Identify sustainability-related risks and opportunities	Build the issue universe	Risk/opportunity inventory	Only looking at climate and ignoring broader sustainability topics
3	Assess materiality	Filter to decision-useful matters	Material topics list	Confusing social importance with investor materiality
4	Evaluate current and anticipated financial effects	Connect to cash flows, financing, and cost of capital	Qualitative and quantitative analysis	No attempt to quantify where feasible
5	Draft disclosures under four pillars	Provide structured reporting	Governance, strategy, risk management, metrics/targets	Reporting only metrics without explaining strategy
6	Ensure connected information	Align with financial statements and narrative reporting	Coherent annual report	Sustainability section contradicts accounting assumptions
7	Prepare comparatives, controls, and approvals	Improve reliability and governance	Reviewed disclosure package	Treating first-year reporting as a one-time exercise

Conceptual method for materiality

A useful internal sequence is:

1. Identify the sustainability issue
2. Ask whether it could reasonably affect enterprise prospects
3. Determine whether the effect could influence primary users
4. Assess time horizon and likely channels of impact
5. Decide what governance, strategy, risk, and metric disclosures are needed

Sample calculation input

The water-scarcity example in Section 10 is a good example of how companies may estimate financial effects to support IFRS S1 disclosure.

Common mistakes

• assuming only direct costs matter,
• ignoring financing effects,
• ignoring supply-chain dependencies,
• reporting targets without baseline or progress data,
• using generic industry text without company-specific analysis.

Limitations

• many sustainability effects are uncertain and forward-looking,
• value-chain data can be incomplete,
• comparability improves over time but is not automatic,
• internal estimation methods are not standardized across all firms.

12. Algorithms / Analytical Patterns / Decision Logic

IFRS S1 does not prescribe computer algorithms, but it is commonly implemented using structured analytical patterns.

Analytical Pattern	What It Is	Why It Matters	When to Use It	Limitations
Materiality decision tree	A step-by-step filter to decide whether an issue is material	Prevents over-reporting and under-reporting	At topic selection stage	Heavy judgment is still required
Scenario analysis	Examination of possible future conditions and business effects	Helps with resilience and forward-looking disclosures	For strategic and long-term risks	Results depend heavily on assumptions
Value-chain mapping	Mapping upstream and downstream dependencies	Identifies hidden exposures outside owned operations	For supply-chain or customer-related issues	Data collection can be difficult
Risk heat map	Ranking issues by likelihood and magnitude	Supports prioritization and governance reporting	In enterprise risk management	Heat maps can oversimplify complex interactions
Interoperability mapping	Matching IFRS S1 disclosures to other frameworks	Reduces duplication across jurisdictions	For multinational reporting	Not all frameworks map perfectly
Control maturity assessment	Evaluating reporting systems, owners, and controls	Improves reliability and readiness for assurance	During implementation	Can become bureaucratic if not focused

When these patterns are most useful

• first-year implementation,
• board education,
• multi-jurisdiction reporting,
• sector-specific risk assessment,
• moving from narrative ESG reporting to controlled reporting.

13. Regulatory / Government / Policy Context

Global standard-setting context

IFRS S1 is issued by the ISSB under the IFRS Foundation. It is intended as a global baseline for sustainability-related financial disclosures.

This means:

• it is internationally designed,
• it can be adopted or referenced by local regulators,
• it does not automatically become law everywhere.

Major compliance point

Caution: IFRS S1 is not universally mandatory by default. Whether a company must use it depends on local laws, regulator decisions, stock exchange rules, and any endorsement or adoption mechanism in its jurisdiction.

Relevance to securities regulators and exchanges

Securities regulators care about:

• investor protection,
• consistent disclosure,
• material information,
• market integrity.

A regulator may require, permit, or incorporate IFRS S1-type disclosures into listed-company reporting frameworks.

Relevance to accounting standards

IFRS S1 is related to, but separate from, IFRS Accounting Standards.

• IFRS Accounting Standards cover recognition, measurement, presentation, and disclosure in financial statements.
• IFRS S1 covers sustainability-related financial disclosures outside the core financial statement line items, but connected to them.

Assurance and audit context

IFRS S1 itself is a disclosure standard, not an assurance standard. However:

• companies may seek limited or reasonable assurance depending on market needs or regulation,
• auditors and assurance providers may review controls and consistency,
• governance and internal documentation become more important over time.

Taxation angle

There is no special tax formula inside IFRS S1. However, tax can become relevant when sustainability-related matters affect:

• capital investments,
• restructuring,
• incentives,
• penalties,
• operating costs,
• cash flow forecasts.

Public policy impact

IFRS S1 can influence public policy by:

• improving transparency,
• supporting better capital allocation,
• reducing greenwashing,
• helping regulators build more coherent disclosure regimes.

Geographic policy note

Jurisdictions differ significantly in how they treat IFRS S1. Some use it as a baseline, some have parallel systems, and some have broader or narrower requirements. Always verify the latest position for the reporting date.

14. Stakeholder Perspective

Stakeholder	What IFRS S1 Means to Them	Main Concern
Student	A modern sustainability reporting standard	Understanding materiality and the four pillars
Business owner	A way to explain financially relevant sustainability issues to funders	Cost and practicality of implementation
Accountant	A disclosure framework linked to financial reporting discipline	Consistency, controls, materiality, comparatives
Investor	A tool to assess resilience and value risk	Whether disclosures are specific and decision-useful
Banker / lender	A source of borrower risk information	Impact on repayment capacity and financing terms
Analyst	A structured input into valuation and forecast models	Quality of quantified assumptions and governance
Policymaker / regulator	A potential baseline for market disclosure rules	Adoption design, comparability, enforcement

15. Benefits, Importance, and Strategic Value

Why it is important

• It improves the quality of sustainability-related financial disclosure.
• It helps investors focus on what matters.
• It pushes sustainability reporting away from generic claims.

Value to decision-making

IFRS S1 helps decision-makers assess:

• risk exposure,
• strategic resilience,
• capital needs,
• financing risk,
• management quality.

Impact on planning

Companies often improve:

• enterprise risk management,
• scenario planning,
• capex prioritization,
• board reporting,
• internal control systems.

Impact on performance

Better disclosure can support:

• more disciplined management actions,
• earlier recognition of operational vulnerabilities,
• improved investor dialogue.

Impact on compliance

Where used or adopted, IFRS S1 gives a structured path to disclosure readiness.

Impact on risk management

It strengthens risk management by requiring clearer processes for identifying, assessing, prioritizing, and monitoring sustainability-related risks and opportunities.

16. Risks, Limitations, and Criticisms

Common weaknesses

• dependence on management judgment,
• inconsistent data quality,
• uneven industry maturity,
• difficulties in value-chain data collection.

Practical limitations

• not every financially relevant sustainability issue is easy to quantify,
• some companies lack robust internal systems,
• first-year reporting can be resource-intensive.

Misuse cases

• using IFRS S1 as a branding exercise,
• reporting only positive stories,
• copying competitor disclosures without company-specific evidence.

Misleading interpretations

Some users wrongly assume that: – IFRS S1 covers only climate
