IFRS S2 climate disclosure gap assessment: a practical first pass

A climate disclosure gap assessment should identify which reporting requirements are supported by current evidence and which need further analysis or management decisions. It should not begin by rewriting a general sustainability policy under new headings.

This guide is for teams organising climate-related reporting around IFRS S2 or responding to a request for an initial gap review. It offers a preparation method and a reusable gap record. It does not determine whether IFRS S2 is mandatory for a particular business or establish compliance with the Standard.

Confirm why the business is using IFRS S2

Record whether the request comes from a jurisdictional requirement, a parent company, a capital provider or a voluntary reporting decision. Agree the reporting entity, period, intended audience and basis of preparation. Do not assume that IFRS S2's effective date makes it mandatory for every Indian company.

IFRS S2 Climate-related Disclosures addresses climate-related risks and opportunities that could reasonably affect cash flows, access to finance or cost of capital over different time horizons. Its four content areas are governance, strategy, risk management, and metrics and targets. The IFRS Foundation's implementation overview explains that IFRS S2 is applied with IFRS S1, which provides overarching requirements.

Create a version-control note. The ISSB issued targeted amendments to IFRS S2's greenhouse gas disclosures in December 2025, effective for reporting periods beginning on or after 1 January 2027, with early application permitted. Check the relevant version and any jurisdictional adoption arrangements before finalising the review. IFRS Foundation amendment announcement

Build one gap record for each disclosure question

Use these fields to keep the assessment reviewable:

• Requirement or disclosure question and source paragraph

• Relevant entity, activity and reporting period

• Existing information and its owner

• Evidence reference and date

• Status: supported, partly supported, missing or applicability decision needed

• Work required and the decision-maker responsible

• Dependencies, target date and closure evidence

Do not treat the four content-area headings as a complete checklist. Map the detailed requirements applicable to the reporting basis and document materiality judgments. Keep questions about applicability distinct from questions about whether the data exists.

A short finding is often more useful than “partially compliant”. For example: “The committee mandate includes climate oversight, but no current-period evidence was supplied showing the information reviewed or decisions made.” This tells the owner what needs checking without inventing a control failure.

Test governance against the way decisions are made

Collect mandates, responsibility charts, relevant meeting records and examples of information provided to management. Ask who reviews climate matters, how frequently they are discussed and how important findings reach the people responsible for strategy and capital decisions.

Check whether the draft describes actual arrangements or an intended future process. If a committee is proposed but not established, keep that distinction explicit. Ask the owner to explain how governance arrangements operated during the reporting period, rather than relying only on a recently updated policy.

Connect risks and opportunities with the business

For each identified matter, record the affected site, asset, product or business relationship; the relevant time horizon; available evidence; and the possible financial pathway. Physical risks and transition risks require different questions. Potential opportunities also need an evidence-based explanation rather than an unsupported growth claim.

Check the risk-management process as well as the resulting list. Ask how the business identifies, assesses, prioritises and monitors climate-related risks, who reviews changes, and how the process connects with overall risk management. Record the methods and evidence actually used, including whether opportunities are considered, instead of assuming the general risk policy covers climate in practice.

A hypothetical risk-to-evidence record

This example is illustrative and does not describe a Nitium client or a climate model.

A manufacturer identifies possible interruption of production because a key logistics route is exposed to flooding. An initial record might identify the route, affected products, historic disruption information, alternative-route options and the operations owner.

The financial pathway could include additional freight cost or delayed deliveries. These are hypotheses to assess, not calculated financial effects. Finance and operations would need to evaluate the exposure, assumptions and relevant time horizons before a disclosure claimed a quantified impact or a resilient operating model.

Use this record to identify the next work package: better location data, a logistics review, financial analysis or specialist climate input. Avoid assigning a precise loss estimate merely to fill a reporting template.

Separate a gap review from scenario analysis

IFRS S2 requires climate-related scenario analysis to inform the assessment of climate resilience. The approach should be commensurate with the entity's circumstances and consider reasonable and supportable information available without undue cost or effort. The IFRS Foundation's climate-resilience factsheet explains these provisions.

A gap review can check whether analysis exists, who prepared it, what assumptions it uses and how the results informed decisions. It cannot create a completed resilience assessment by adding a paragraph about future weather. Scope any required analytical or modelling work separately and involve suitable specialists.

Similarly, describe transition plans according to what the business has actually decided. IFRS S2 does not itself require an entity to have a transition plan; it includes disclosure requirements relevant to climate-related transition and any plan the entity has.

Check metrics, targets and financial connections

Assemble the emissions inventory, other relevant climate metrics and target documentation. For each target, check the baseline, boundary, metric, timeframe, approval and method used to track progress. A proposed target should remain labelled as proposed.

Ask finance to review links with budgeting, capital expenditure, financial effects and assumptions used elsewhere in reporting. Investigate inconsistencies rather than forcing different documents to use the same wording. Requirements and methods can differ, but the business should be able to explain the differences.

Finish with prioritised actions, named owners and a list of decisions that block supported disclosure. The first pass is useful when it makes the next work clear, including what cannot yet be concluded.

Discuss a climate reporting review

Nitium's climate-related reporting support covers disclosure mapping, evidence checklists, draft narrative and prioritised gaps. Discuss your climate-reporting scope with existing risk records, emissions data and the request you need to address. Specialist scenario modelling and independent assurance are outside the services described on this site.
