UK SRS S2 Explained: Climate Disclosure Requirements and How to Start

Functional visual created for London Reporting Academy. The visual is illustrative and should be read with the article.

UK SRS S2 is not simply a greenhouse gas inventory standard. Its central purpose is to explain how climate-related risks and opportunities affect the entity’s prospects and how governance, strategy, risk management, metrics and targets respond to those effects. The emissions disclosures are important, but they sit inside a broader investor-focused account of the business model, financial planning and resilience.

The standard can be used voluntarily by any entity. For listed companies and other organisations already subject to UK climate-reporting duties, it can also serve as a readiness framework for the proposed transition from TCFD-aligned reporting to UK SRS-based reporting. The legal basis and the technical basis should therefore be recorded separately.

Paragraphs 1-2 require information useful to primary users of general purpose financial reports when making decisions about providing resources to the entity. The information is limited to climate-related risks and opportunities that could reasonably be expected to affect cash flows, access to finance or cost of capital over the short, medium or long term.

Paragraph 3 covers climate-related physical risks, climate-related transition risks and climate-related opportunities. Paragraph 4 excludes matters that could not reasonably be expected to affect the entity’s prospects. This is an investor-focused materiality lens, not a requirement to publish every environmental impact or every climate-related data point available to the organisation.

A strong first-year process therefore begins with business and financial pathways: assets, operations, products, supply chains, customers, financing, insurance, regulation, technology and market demand. A generic list of climate topics is not enough.

UK SRS S2 paragraph C2 requires UK SRS S2 and UK SRS S1 to be applied at the same time, insofar as the S1 requirements relate to climate disclosures. UK SRS S2 supplies the climate-specific content; UK SRS S1 supplies the reporting architecture.

In practice, S1 determines how materiality is assessed, which reporting entity is used, how connected information is presented, where and when the disclosures are published, how comparatives and estimates are handled, and whether an explicit and unreserved compliance statement is supportable. A climate report that answers the four S2 pillars but ignores these S1 foundations is incomplete.

Paragraph 10 requires each material climate-related risk or opportunity to be described, physical or transition risks to be classified, and the relevant short-, medium- and long-term horizons to be stated. The entity must also explain how its definitions of those horizons connect to strategic planning.

Paragraph 11 requires all reasonable and supportable information available at the reporting date without undue cost or effort. That includes past events, current conditions and forecasts. The phrase is a proportionality mechanism, not permission to stop at information already stored in the sustainability team.

Paragraph 12 permits, but does not require, specific reference to the IFRS S2 Industry-based Guidance when identifying risks and opportunities. The entity still needs decision-useful industry information. It should document which industry sources it considered, what it used and why its selected sources are appropriate.

Paragraphs 13-14 require the entity to show where risks and opportunities are concentrated in its business model and value chain, how it has responded or plans to respond, how activities are resourced, and progress against previously disclosed plans. If the entity has a climate-related transition plan, the plan, key assumptions and dependencies are disclosed. UK SRS S2 does not require an entity to create a transition plan merely to satisfy the disclosure standard.

Paragraphs 15-21 require current and anticipated effects on financial position, financial performance and cash flows. The disclosure should connect climate matters to revenue, operating costs, capital expenditure, asset carrying amounts, impairments, provisions, financing needs, liquidity, cost of capital and cash-flow timing where relevant.

Quantitative information can be a single amount or a range. Quantification is not required where effects are not separately identifiable, measurement uncertainty is so high that the result would not be useful, or the entity lacks the skills, capabilities or resources for anticipated effects. Where quantitative information is not provided, the entity must explain why, provide qualitative information and identify likely affected financial-statement line items, totals or subtotals. Relief from a number is not relief from the financial-effects disclosure.

Paragraph 22 requires climate-related scenario analysis to assess climate resilience. The approach must be commensurate with the entity’s circumstances. The standard does not prescribe a single model, scenario provider or level of mathematical sophistication.

A proportionate first-year approach can begin with a limited number of relevant scenarios, explicit assumptions, defined time horizons, selected operations or value-chain exposures, and a documented assessment of strategic vulnerabilities and response capacity. The analysis must still be company-specific and must inform the resilience disclosure; a generic narrative copied from a sector report is not scenario analysis.

The evidence file should show the scenarios selected, why they are relevant, key inputs and assumptions, the scope of operations and risks tested, management challenge, limitations, and the conclusions that influenced strategy or financial planning.

Paragraphs 33-37 cover quantitative and qualitative targets set by the entity and targets required by law or regulation. For each target, the report explains the metric, objective, scope, period, base period, milestones, absolute or intensity form and how the latest international climate agreement and relevant jurisdictional commitments informed the target.

The entity also explains how the target was set and reviewed, whether the target or methodology was validated by a third party, how progress is monitored, revisions made, performance and trends. Greenhouse gas targets require additional transparency on gases and scopes covered, gross versus net targets, sectoral decarbonisation and planned use of carbon credits.

A public net-zero ambition without a defined boundary, base year, milestones, gross-emissions pathway and governance evidence is not a substitute for the target disclosures.

Illustrative scenario - a UK manufacturer identifies heat stress at two sites, carbon-pricing exposure in purchased materials and demand growth for a lower-carbon product. The reporting team initially treats the issues as three narrative themes.

A stronger process maps the physical risk to production downtime and adaptation capex; the transition risk to input cost and margin sensitivity; and the opportunity to revenue assumptions and capacity investment. Scenario analysis tests whether the strategy remains viable under different temperature and policy pathways. The report then connects governance, risk management, metrics and targets to the same three items.

The example does not determine materiality for any real entity. The conclusion depends on the entity’s facts, planning horizons, evidence and primary-user information needs.

Confirm the reporting basis. Record whether use is voluntary, required by an existing climate rule, or preparatory for a proposed UK SRS route. Decide whether any UK SRS compliance claim is intended.

Establish the S1 foundations. Confirm reporting entity, period, financial-statement links, materiality method, time horizons, report location and approval responsibilities.

Build a climate risk-opportunity register. Link each item to business-model and value-chain exposure, prospects, horizon, financial pathways, metrics and disclosure implications.

Design scenario and financial-effects work together. Finance, strategy and risk teams should agree assumptions, planning links and evidence before drafting begins.

Stabilise metrics and controls. Complete Scope 1-3 screening, industry-metric selection, target controls, data ownership, review and annual-report sign-off.
