Separate climate risks, opportunities and assumptions before making a claim
Before a climate statement leaves the working file, identify what the business knows, what it has inferred and what it has assumed. A possible disruption, a promising product idea and a calculated sensitivity need different explanations. Giving each a clear record helps finance, operations and reporting colleagues review the same proposition.
This guide is for teams preparing initial climate-risk and opportunity records. It offers a working method for checking a claim’s basis and limits. The method and fictional examples are preparation aids; they do not establish reporting compliance, climate resilience or an investment recommendation.
Start with the business question
IFRS S2 Climate-related Disclosures addresses physical risks, transition risks and climate-related opportunities that could reasonably affect a company’s cash flows, access to finance or cost of capital over short, medium or long time horizons. This provides useful context for asking how a climate matter connects to the business. It does not make every environmental observation a financial forecast.
Write the proposed statement at the top of the record. For example: “Flooding could interrupt packing at Site A” or “A new product could meet a customer’s changing requirements.” Then identify the decision the statement is meant to inform. That might be further investigation, a budget discussion or a draft disclosure. Keep the intended audience visible.
Give the subject and its evidence separate labels
Physical risks can arise from events such as floods or from longer-term climatic changes. Transition risks arise from the move towards a lower-carbon economy, including changes in policy, technology and markets. Opportunities concern potential benefits, such as products meeting changing customer needs. The same change can create both a risk and an opportunity. IFRS Foundation identification guidance, Appendix A
Use a second label for the support behind each statement:
Observed fact: a dated record establishes what was measured, recorded or decided within a defined scope.
Estimate: a method derives an unknown quantity from available evidence; retain the calculation and uncertainty.
Assumption: an input is selected for analysis; record its rationale and what changes if it is wrong.
Open hypothesis: a possible connection still needs investigation.
A risk can contain facts, estimates and assumptions. A response can be proposed, approved, implemented or tested. Record those states explicitly. Buying equipment, for example, establishes a purchase; demonstrating its effect needs separate evidence.
Fix the boundary before attaching a number
Identify the legal entity, site or business activity, the relevant locations and the part of the value chain being considered. Climate-related dependencies can extend through suppliers, logistics and customers. The IFRS Foundation implementation overview explains why the value chain matters when identifying risks and opportunities.
Give every record a reference date and explicit time horizon. Explain why that horizon fits the decision, such as a lease term or equipment life. Short, medium and long term can differ between businesses; the Foundation’s guidance, page 28 relates them to business and planning circumstances.
Keep different boundaries visible. A regional climate projection, one site’s operating records and a group-wide revenue total describe different populations. Before combining them, document the link. Record important exclusions, including an unassessed supplier or alternative transport route. An exclusion limits what the claim can cover.
Show the route from a climate driver to a business effect
For each risk, work through six questions. This is an optional review sequence, not an IFRS disclosure checklist.
Driver: What climate hazard or transition change is being considered, and why is it climate-related?
Connection: Which asset, activity or business relationship could encounter that change?
Susceptibility: What would make that asset or dependency vulnerable, and what protection already exists?
Operational effect: How could production, service delivery, purchasing or demand change?
Financial pathway: Which cost, revenue or cash-flow item could be affected, under what conditions?
Response and remaining uncertainty: What could management change, what would it require, and what remains unresolved?
Attach evidence to each connection. A weather map alone cannot establish a company’s loss. A higher energy bill needs investigation into volume, tariffs, production and other causes before it is attributed to climate transition. Where a connection is missing, describe the next check instead of supplying a precise result.
Keep scenario inputs attached to the result
Scenario analysis explores possible outcomes under uncertainty. IFRS S2 uses it to inform an assessment of climate resilience, with an approach suited to the company’s circumstances. The analysis and the assessment need a clear explanation of inputs, assumptions and uncertainty. IFRS Foundation climate-resilience factsheet
For the working record, retain the scenario source and version, locations, horizon, variables and important assumptions. Explain why they fit the question. Keep a result conditional on those inputs; calculating it does not establish that the conditions will occur. Label a simple sensitivity exercise as such.
IFRS S2 does not prescribe which scenarios to select. Its approach calls for relevant, supportable choices, and qualitative analysis can be appropriate in some circumstances. IFRS Foundation scenario-analysis slides, page 13 A short spreadsheet exercise alone does not demonstrate that a business has completed its climate-resilience assessment.
A fictional flood record keeps five conclusions apart
Every fact, amount and document below is invented for this example. The case describes no real site, client, climate dataset or forecast. It illustrates one selected risk record, not a complete company assessment.
Recorded site conditions
In the fictional file, a layout dated 30 September 2026 places the electrical cabinet serving Site A’s packing line on the ground floor beside the loading entrance. Operations confirms that no alternative supply has been tested. The record covers this site and the 2027–2029 planning period. Supplier and transport dependencies remain outside this selected exercise.
Hazard and interruption assumptions
The team asks what would happen if floodwater reached the cabinet and packing stopped for two days. Those conditions are selected stress assumptions. Site-specific flood likelihood, water depth and equipment damage have not been established. The layout supports the location of the dependency; it does not establish that flooding will reach it.
Conditional business effect
Assume outsourced packing would add ₹1,00,000 per day above the costs already allowed in the operating budget. Two days multiplied by ₹1,00,000 gives ₹2,00,000, or ₹2 lakh, for that conditional interruption. The assumed incremental rate still needs support from capacity checks and comparable supplier terms.
The calculation excludes repairs, delivery penalties and any unfulfilled orders. It is neither a complete event-loss estimate nor an expected annual loss. Event probability is unknown, and no annual frequency has been assigned. Lost revenue must not be added automatically if outsourced packing would preserve the same sales.
Possible response and its cost
Raising the cabinet is recorded as a possible response, with an invented ₹3 lakh planning allowance. No engineering design, supplier quotation, approval or effectiveness assessment exists. Keep that allowance separate from the ₹2 lakh interruption sensitivity. These two figures cannot establish payback, an avoided annual loss or a decision to invest.
What the record can support
A bounded description would be: “Initial screening identified a ground-floor electrical dependency at Site A. We are assessing how flood conditions could affect operations. The likelihood, financial effect and response cost remain unconfirmed.”
The next work is clear: obtain suitable site-specific hazard information, test the interruption and outsourcing assumptions, and assess feasible responses. Assign those questions to appropriate operations, finance and specialist reviewers before strengthening the statement.
Test an opportunity through its own dependencies
An opportunity needs a route to a benefit as explicit as a risk’s route to a cost. Ask what is changing, what the business can offer, what customers would need to accept, what delivery would require and which costs would accompany it.
Consider a separate fictional case: two customers ask for product-emissions information. Those requests support a statement about information demand. A proposal to develop a lower-emissions product still needs a credible measurement basis, technical feasibility, customer acceptance, pricing, capacity and cost evidence before anyone projects a benefit.
Keep a possible decline in demand for the existing product and a possible benefit from the proposed product in linked records. Different timing, customers and conditions may apply. Avoid cancelling the risk with a speculative opportunity or describing an untested proposal as an achieved saving.
Review the wording with the record open
Before using the statement in a report, presentation or website, check that another reviewer can answer these questions:
What exactly is the risk, opportunity or response, and what makes it climate-related?
Which facts, estimates, assumptions and unresolved hypotheses support it?
Are the locations, value-chain boundaries and time horizons visible?
Can each business connection and calculation be traced to a source?
Does the wording preserve conditions, exclusions and the response’s actual status?
Who owns the unresolved questions, and what new evidence would change the statement?
Retain the reviewed wording, reviewer, date and evidence version together. Refresh the record when an important input changes. A shorter public sentence can still keep its essential boundary and conditions; leave any unsupported conclusion out.
Use the IFRS S2 gap-assessment guide to map broader reporting gaps. For an emissions commitment, use the net-zero starting-point guide to review the pledge and baseline.
Nitium’s climate-related reporting support covers disclosure mapping, evidence checklists, draft narrative and prioritised gaps. Discuss the reporting question with a non-confidential summary of your draft statement and the evidence available. Specialist scenario modelling and independent assurance are outside the services described on the site.
