Short answer
The answer, before the reasoning
IFRS S1 strategy disclosure should explain the decision pathway for each material sustainability-related risk or opportunity. Describe the risk or opportunity and time horizon; explain current and anticipated effects and where exposure is concentrated in the business model and value chain; show the entity's response, resource allocation, progress and trade-offs; connect the issue to current and anticipated financial effects and financial planning; and explain resilience.
Commercial sensitivity is a narrow opportunity-only exemption, not a general reason to omit strategic information.

WHO THIS IS FOR
Sustainability reporting, finance, strategy, corporate development, operations, investor relations and risk teams, plus consultants and reviewers preparing the strategy pillar under IFRS S1.
Technical status
STANDARD STATUS
IFRS S1 and the original IFRS S2 requirements are effective for annual reporting periods beginning on or after 1 January 2024, with earlier application subject to applying the companion Standard at the same time. The current IFRS S2 issued text incorporates targeted greenhouse gas amendments issued in December 2025. Those amendments apply for annual periods beginning on or after 1 January 2027, with earlier application permitted, and do not alter the governance, strategy or risk-management architecture explained in this article.
Strategy disclosure should show the decision pathway
IFRS S1 strategy disclosure is not a sustainability strategy summary. It explains how sustainability-related risks and opportunities affect the entity's business model and value chain, strategy and decision-making, current and anticipated financial position, financial performance and cash flows, and the resilience of the strategy and business model.
The reader should be able to follow a sequence: identify the entity-specific risk or opportunity and time horizon; locate the exposure or concentration; explain current and anticipated business effects; describe the response, resource allocation, progress and trade-offs; and connect those decisions to current and anticipated financial effects and resilience.
Figure 1. Strategy disclosure connects exposure, response and financial consequences rather than listing sustainability initiatives.
In practice
| STRATEGY MODULE | KEY QUESTION | EVIDENCE |
|---|---|---|
| Risk or opportunity | What entity-specific risk or opportunity could affect prospects, and over which time horizon? | Risk/opportunity register, materiality judgement, time-horizon definitions. |
| Business model and value chain | What current and anticipated effects arise and where are they concentrated? | Segment, site, asset, supplier, market and customer exposure analysis. |
| Response and decisions | How has the entity responded and how does it plan to respond? | Strategy papers, operational plans, transaction and capital decisions. |
| Resources and progress | How are actions resourced and what progress has been made? | Budgets, capex, opex, people, funding, milestones and performance data. |
| Trade-offs | Which alternatives and competing effects were considered? | Options analysis, impact, risk and financial evidence, decision rationale. |
| Financial effects and resilience | How have financial position, performance and cash flows changed or may change, and can the strategy adjust? | Financial statements, forecasts, scenarios, impairment inputs and resilience assessment. |
In practice
What IFRS S1 requires in the strategy pillar
| REQUIREMENT AREA | SOURCE-GROUNDED CONTENT |
|---|---|
| Risks, opportunities and time horizons | Describe the sustainability-related risks and opportunities expected to affect prospects; specify short-, medium- and long-term horizons; explain how those definitions link to strategic planning. |
| Business model and value chain | Describe current and anticipated effects and where risks and opportunities are concentrated, such as geographies, facilities or asset types. |
| Strategy and decision-making | Explain current and planned responses, progress against previously disclosed plans and trade-offs considered. |
| Current and anticipated financial effects | Explain effects on financial position, performance and cash flows for the reporting period and anticipated effects over the relevant time horizons, considering financial planning. |
| Resilience | Provide a qualitative and, if applicable, quantitative assessment of the capacity of strategy and business model to adjust to uncertainties arising from sustainability-related risks. |
Rule
NOT A PRESCRIBED STRATEGY FORMAT
IFRS S1 does not require every entity to have a stand-alone sustainability strategy, a transition plan for every topic, a fixed scenario set for all sustainability risks, or a universal capital-allocation table. It requires material information that enables users to understand the entity's actual strategy, decisions, financial effects and resilience.
In practice
| MYTH | The strategy section should describe every sustainability programme in the organ |
|---|---|
| REALITY | The strategy section should focus on material information about risks and opportunities that could affect prospects and explain the corresponding business effects, decisions, resources, trade-offs, financial effects and resilience. |
Use entity-specific risk and opportunity narratives
A label such as "climate change", "human capital" or "biodiversity" is too broad to anchor a strategy disclosure. The narrative should identify the mechanism, exposure, concentration and expected timing. Entity-specific wording improves the rest of the disclosure because it clarifies which decisions, resources and metrics are relevant.
The narrative should not overstate certainty. Words such as "could", "is expected to" or "management assesses" can communicate the status of the judgement, provided the underlying evidence and assumptions are explained where material.
In practice
| GENERIC LABEL | ENTITY-SPECIFIC NARRATIVE |
|---|---|
| Climate transition risk | Customer procurement requirements and planned heavy-vehicle regulation could reduce demand for the entity's current fleet services and require accelerated fleet replacement over the medium term. |
| Workforce risk | Dependence on a limited pool of licensed technicians in two regions could delay maintenance capacity expansion and increase contractor cost over the short and medium term. |
| Nature-related risk | Production at Plant C depends on reliable surface-water supply in a catchment with increasing demand and seasonal restrictions, creating medium-term production and investment exposure. |
| Sustainability opportunity | Growing customer demand for verified lower-impact packaging could increase revenue from the entity's recyclable product line, subject to feedstock availability, certification and production-capacity investment. |
Explain business-model and value-chain effects and concentrations
IFRS S1 requires both current and anticipated effects and a description of where risks and opportunities are concentrated. Concentration is not limited to geography. It can arise in facilities, asset classes, products, suppliers, customers, workforce capabilities, markets, technologies, financing structures or regulatory regimes.
In practice
| CONCENTRATION LENS | ANALYSIS QUESTIONS | POSSIBLE DISCLOSURE DETAIL |
|---|---|---|
| Geography / site | Which locations carry disproportionate exposure or opportunity? | Share of capacity, revenue, margin, assets or critical input located in affected areas. |
| Assets / technology | Which asset types face obsolescence, damage, upgrade or redeployment? | Asset age, remaining life, retrofit options, replacement cycle and impairment indicators. |
| Supply chain | Which inputs or suppliers are concentrated, constrained or hard to substitute? | Source regions, supplier tiers, contract terms, alternatives and transition timing. |
| Customer / market | Where could demand, tender requirements or product preferences shift? | Revenue exposure, order book, product portfolio and customer concentration. |
| Workforce | Which skills or worker groups are critical to the response? | Roles, geographies, training capacity, labour cost and redeployment requirements. |
| Finance / regulation | Which funding, covenant, insurance or jurisdictional conditions affect the plan? | Funding sources, cost of capital, coverage, regulatory timeline and policy dependency. |
Rule
DISAGGREGATION CONTROL
A group-wide statement can obscure a material concentration. The reporting team should test whether information needs to be disaggregated by geography, segment, facility, asset, product, supplier or customer group so that material information is not hidden by aggregation.
Responses, resource allocation and progress
IFRS S1 paragraph 33 requires information about how the entity has responded and plans to respond, progress against previously disclosed plans, and trade-offs considered. A response narrative should distinguish actions already approved and underway from aspirations, proposals or options still under assessment.
Resource allocation should connect to financial planning. Where the response depends on uncommitted capital, future financing, technology development, supplier capacity or policy support, these dependencies and uncertainties can be material. They should not be hidden behind a confident plan narrative.
In practice
| RESPONSE FIELD | WHAT TO DISCLOSE | EVIDENCE / CONTROL |
|---|---|---|
| Status | Implemented, approved, planned, conditional, under assessment or discontinued. | Approval status and date; avoid presenting proposals as committed plans. |
| Action | Operational, product, sourcing, pricing, financing, partnership, transaction or risk-transfer response. | Plan, owner, milestones and dependencies. |
| Resources | Current and planned financial, human, technological or other resources. | Budget, capex, opex, headcount, funding source and capacity. |
| Progress | Quantitative and qualitative progress against previously disclosed plans. | Milestones, metric trend, delay, corrective action and revised expectations. |
| Residual exposure | What risk remains after the response and how it is monitored. | Residual risk assessment, thresholds and contingency. |
Trade-offs are part of the strategy disclosure, not an admission of failure
A trade-off exists when a strategic option improves one outcome while worsening another, changes the timing or distribution of effects, or requires choosing between competing risks, opportunities or resources. IFRS S1 explicitly asks for trade-offs considered. This makes the disclosure more decision-useful because it explains why the entity selected one response over another.
In practice
| TRADE-OFF EXAMPLE | QUESTIONS TO EXPLAIN |
|---|---|
| New facility location | How did the entity compare logistics, community employment, biodiversity, water, energy, regulatory and cost implications? |
| Accelerated asset replacement | How did it compare near-term capital and write-off effects with future operating, regulatory and market exposure? |
| Supplier exit versus remediation | How did it compare continuity, leverage, worker impacts, cost and risk of continued association? |
| Product redesign | How did it compare material availability, performance, customer demand, price and environmental or social outcomes? |
| Workforce restructuring | How did it compare cost reduction, skills retention, community effects, execution capacity and future demand? |
Hypothetical scenario
ILLUSTRATIVE DRAFTING PATTERN
The entity considered Option A and Option B. Option A reduced near-term regulatory exposure but required earlier capital expenditure and created supply constraints. Option B preserved liquidity but increased medium-term customer and compliance risk. Management selected a phased version of Option A, subject to supplier capacity and funding milestones. This wording is illustrative and must be adapted to actual facts and material information.
Illustrative only. It shows how the decision is made, not wording that can be copied or relied on.
Connect current and anticipated financial effects to financial planning
The financial-effects disclosure should describe how risks and opportunities affected financial position, performance and cash flows in the reporting period and how they are expected to affect those elements over the short, medium and long term. It also identifies risks and opportunities that create a significant risk of a material adjustment to asset and liability carrying amounts in the next annual reporting period.
For anticipated effects, the entity considers investment and disposal plans, including plans not yet contractually committed, planned funding sources, and expected changes in financial performance and cash flows. Quantitative information can be a single amount or a range. IFRS S1 provides relief from separate quantitative information in specified circumstances, but the entity must explain why and provide the required qualitative information and, where useful, combined quantitative effects.
In practice
| FINANCIAL PATHWAY | CURRENT EFFECTS | ANTICIPATED EFFECTS / PLANNING |
|---|---|---|
| Revenue and demand | Product mix, lost contracts, price or volume effects. | Forecast demand, new products, market entry or exit, uncertainty. |
| Operating cost | Energy, labour, input, compliance, insurance or remediation cost. | Efficiency plan, supply change, wage and service assumptions, contingencies. |
| Assets and capex | Damage, impairment indicator, depreciation, retrofit or maintenance. | Investment, disposal, retirement, innovation, useful life and funding. |
| Liabilities and provisions | Legal, remediation, contract or restructuring effects. | Expected obligations, uncertainty, timing and possible changes. |
| Cash flow and finance | Working capital, operating or financing cash effects. | Funding source, covenant, access, cost of capital and liquidity planning. |
Rule
RELIEF IS NOT SILENCE
Where separate quantitative financial effects are not provided because effects are not separately identifiable, measurement uncertainty is too high or skills and resources are unavailable for anticipated effects, the entity still explains the reason and provides the qualitative and combined information required by IFRS S1 paragraph 40.
Commercially sensitive opportunities: a narrow exemption
IFRS S1 provides a limited exemption for commercially sensitive information about a sustainability-related opportunity. It is not a general confidentiality exemption and it does not apply to sustainability-related risks.
In practice
| CONDITION | REVIEW TEST |
|---|---|
| The opportunity information is not already publicly available. | Check reports, investor materials, tenders, patents, announcements and other public statements. |
| Disclosure could seriously prejudice economic benefits the entity could otherwise realise. | Document the specific economic harm rather than a generic competition concern. |
| It is impossible to disclose the information in another way, such as aggregation, while meeting the disclosure objective without serious prejudice. | Test redaction, aggregation, ranges, delayed detail and higher-level explanation before omitting. |
| For each omitted item, the entity discloses use of the exemption and reassesses eligibility at each reporting date. | Maintain an item-level exemption record and annual approval. |
Caution
DO NOT OVEREXTEND THE EXEMPTION
Commercial sensitivity cannot be used for risks, broad non-disclosure or information that is merely inconvenient. The exemption should be documented item by item and challenged by legal, reporting and governance reviewers.
Three hypothetical entity-specific narratives
Each example links an entity-specific exposure to concentration, decision, resource, progress, uncertainty and financial pathway. None is a universal compliant clause.
Hypothetical scenario
HYPOTHETICAL EXAMPLE 1 - MANUFACTURER
The entity's principal medium-term transition exposure is concentrated in two gas-fired production lines that account for 46% of segment capacity. Customer tender criteria and projected carbon costs could reduce margin and require accelerated retrofit. The Board approved a two-stage electrification programme with planned capital expenditure, subject to grid-connection timing. Progress was slower than planned because the connection date moved by nine months; the entity revised the commissioning sequence and retained temporary gas capacity, increasing expected operating cost and residual exposure.
Illustrative only. It shows how the decision is made, not wording that can be copied or relied on.
Hypothetical scenario
HYPOTHETICAL EXAMPLE 2 - SOFTWARE GROUP
Dependence on a limited pool of cybersecurity engineers could constrain the planned expansion of regulated-industry services over the short and medium term. Management increased graduate recruitment and established a specialist retention programme. The response requires higher near-term employment cost but is expected to support contract capacity. The principal uncertainty is the time required to develop regulated-sector experience; management monitors vacancy duration, attrition, project delay and gross-margin effects.
Illustrative only. It shows how the decision is made, not wording that can be copied or relied on.
Hypothetical scenario
HYPOTHETICAL EXAMPLE 3 - CONSUMER PRODUCTS
Demand for verified low-impact packaging creates a medium-term opportunity concentrated in three customer categories. The entity is investing in a new product line but relies on certified feedstock and customer acceptance of price premiums. Because detailed product design and customer negotiations are not public, the entity aggregates some opportunity information and separately evaluates whether any item meets the narrow commercial-sensitivity exemption.
Illustrative only. It shows how the decision is made, not wording that can be copied or relied on.
Ten-part drafting structure
1. Name the risk or opportunity in entity-specific terms.
2. State the relevant short-, medium- or long-term horizon and the entity's definition.
3. Describe current and anticipated effects on the business model and value chain.
4. Identify significant concentrations by geography, facility, asset, product, supplier, customer or other relevant lens.
5. Explain the current response and planned response, distinguishing approved actions from options.
6. Describe financial, human, technological and other resources and material dependencies.
7. Report progress against previously disclosed plans, including delays, changes and corrective action.
8. Explain material trade-offs and alternatives considered.
9. Connect current and anticipated effects to financial position, performance, cash flows and financial planning.
10. Explain resilience, uncertainty, limitations and any narrowly applied commercial-sensitivity exemption.
In practice
| COMMON ERROR | WHY IT IS WEAK | CORRECTION |
|---|---|---|
| Generic topic narrative | It does not reveal the entity-specific mechanism or concentration. | Define the exposure, affected value-chain stage, location, assets, customers or resources. |
| Long list of initiatives | Users cannot see which action responds to which risk or opportunity. | Map actions to exposure, resources, progress, residual risk and financial pathway. |
| Future plan presented as current capability | Approval, funding, technology or implementation may be uncertain. | Separate implemented, approved, planned, conditional and exploratory actions. |
| Only positive progress | Delays, residual exposure and failed assumptions are obscured. | Report material variance, corrective action and changed expectations. |
| Trade-offs omitted | The decision rationale and distribution of effects are hidden. | Explain the alternatives and competing consequences considered. |
| Commercial sensitivity used broadly | The narrow opportunity-only exemption is overstated. | Apply and document all conditions item by item and reassess annually. |
