UK SRS S2 and CDP: How to Reuse Climate Data Without Assuming Compliance

Educational practitioner material. Illustrative examples and wording require adaptation and technical review.

CDP can improve reporting discipline because it asks organisations to collect structured information on governance, risks and opportunities, transition plans, scenarios, emissions, targets and environmental performance. Many fields are aligned with the architecture of IFRS S2, which makes the response a useful data-acquisition and readiness channel for UK SRS S2.

The mistake is to treat the response as the standard itself. The questionnaire has its own routing, definitions, scoring logic, modules, response timing and public-disclosure choices. UK SRS S2 is a disclosure standard for general purpose financial reporting and must be read with UK SRS S1. The two outputs can be supported by one controlled dataset, but their completeness tests and public claims are different.

CDP scores assess aspects such as the detail and comprehensiveness of the response, awareness of environmental issues, management methods and progress towards environmental leadership. That is a different purpose from an explicit and unreserved statement that an entity has complied with every applicable requirement in UK SRS S1 and UK SRS S2.

CDP and UK SRS S2 can draw from the same source systems only after the information passes five reconciliation gates.

Gate 1 - Entity and boundary

Start with the reporting entity, not the questionnaire. CDP organisational boundaries, business activities and routed modules may not automatically match the UK SRS reporting entity. The annual-report team should reconcile legal entities, acquisitions, disposals, joint ventures, associates, leased operations and value-chain activities to the entity that prepares the related financial statements.

For GHG emissions, the record must also support the UK SRS S2 presentation of Scope 1 and Scope 2 emissions for the consolidated accounting group and separately for other investees. A CDP total can be reused only if the underlying data retain those attributes.

Gate 2 - Reporting period and cut-off

CDP’s disclosure cycle and an organisation’s annual reporting timetable may not align. For the 2026 cycle, CDP identifies 16 September as the scoring deadline and the week commencing 26 October as the final deadline for unscored responses and amendments. A UK annual report may relate to a different financial year-end and may be approved months later.

The organisation therefore needs a cut-off memorandum: reporting period; data-extraction date; estimate cut-off; CDP submission date; annual-report authorisation date; subsequent-events process; and the treatment of corrections made after the CDP scoring deadline. Without this control, the same metric can appear with two unexplained values.

Gate 3 - Materiality and disclosure scope

CDP routing and scoring do not replace the UK SRS S1 materiality assessment. The UK report must identify material climate-related risks and opportunities and provide material information without obscuring it. CDP may collect broader information that is useful but not material for the UK report; it may also not capture the exact entity-specific information needed to explain a material effect on prospects.

Create a coverage matrix that links each material UK climate matter to the applicable UK SRS S2 paragraphs, the CDP question or field used as an input, any residual disclosure, evidence owner and review status. “No matching CDP question” is not an omission basis. “CDP answered” is not a completeness conclusion.

Gate 4 - Method, units and definitions

Reconcile units, currencies, exchange rates, emission factors, GWP values, consolidation approach, Scope 2 method, Scope 3 category definitions, base years and restatements. CDP answer options may require a particular format; UK SRS S2 may require a narrative explanation or a different disaggregation. The transformation from master data to each output should be documented and reproducible.

Gate 5 - Evidence, approval and claims

Every significant UK SRS S2 statement should link to evidence and an accountable owner. CDP evidence can be reused where it is current, complete and retained, but the UK report needs its own preparation, review and approval trail. The proposed UK compliance statement should be reviewed separately from the CDP submission declaration and separately from any assurance or verification statement.

CDP can collect detailed scenario information, which makes it a valuable source for the UK SRS S2 resilience disclosure. Reuse should nevertheless be tested. The scenario set used in CDP may have been prepared for a prior strategic cycle, may cover only selected assets or may not translate results into the entity’s financial planning. UK SRS S2 requires an assessment of climate resilience using an approach commensurate with the entity’s circumstances and disclosure of how and when the analysis was carried out, the scenarios and assumptions used, and the implications for strategy and business model.

A reconciliation table should show scenario name, version, source, temperature or hazard pathway, time horizon, geographic and asset coverage, variables, strategic cycle, financial model, limitations, CDP location and UK disclosure location. A generic statement that “scenario analysis was performed” is not enough.

CDP may capture estimated financial impacts, potential costs and opportunities. UK SRS S2 requires these effects to be connected with the related financial statements and general purpose financial reports. Finance should therefore own the bridge from CDP values or ranges to budgets, forecasts, impairment testing, useful lives, provisions, capex, revenue assumptions and cash-flow planning.

Where quantitative UK disclosure is not provided under an available relief, the entity must explain why and provide the specified qualitative information. A blank CDP field, “not evaluated” answer or confidentiality choice does not establish that the UK condition is met.

The most common reconciliation failures concern Scope 2 and Scope 3. The organisation should retain location-based and any market-based calculation, contractual-instrument information, the 15-category Scope 3 screening, included categories, methods, data sources, estimates and exclusions. If UK SRS S2 paragraph C4 first-year relief is used, it must be disclosed as part of the UK reporting basis; the CDP response can still contain Scope 3 information if available.

Verification should also be described precisely. A limited-assurance statement over selected emissions metrics is not assurance over governance, strategy, risk management or the entire UK SRS S2 disclosure. The report should state the subject matter, criteria, period, boundary and level of assurance.

1. Freeze the UK reporting basis and proposed compliance claim before mapping CDP questions.

2. Export or catalogue the CDP response at field level, including question version, routing, unit, period and evidence owner.

3. Reconcile the entity and GHG boundary to the financial reporting entity and UK SRS requirements.

4. Create a date-and-version bridge between the CDP submission cycle and annual-report approval timetable.

5. Map each material UK SRS S2 requirement to a CDP input and identify all residual disclosure work.

6. Normalise methods, units, currencies, factors and definitions in the master data layer rather than editing final text manually.

7. Reperform scenario, financial-effects and industry-metric checks against UK SRS S2 even when CDP content exists.

8. Attach evidence and control sign-offs to the UK disclosure, including any relief or estimate decision.

9. Run a consistency review across CDP, the annual report, GRI reporting, websites, targets and investor presentations.

10. Approve the CDP response and UK SRS report as separate governed outputs with separate claims.

The example illustrates why a version bridge matters. The change log should show which CDP answers are superseded for the annual report, which facts remain valid, which figures were recalculated and whether a CDP amendment is possible or necessary.

Starting the UK crosswalk from the CDP questionnaire rather than from the UK standards and material climate matters.

Using a CDP score as evidence of UK SRS compliance or assurance.

Ignoring differences between the CDP response period and the financial reporting period.

Copying a CDP total without the consolidated-group and investee information needed by UK SRS S2.

Assuming CDP scenario questions fully answer the UK resilience disclosure without checking strategic and financial implications.

Treating CDP confidentiality or “not evaluated” responses as UK SRS reliefs.

Allowing late changes in one channel to create unexplained differences in another.

Publishing a broad assurance claim when only selected CDP or GHG data were verified.

Build a field-level CDP export register, a UK SRS requirement matrix, a boundary memorandum, a reporting-period bridge, a data-method reconciliation, an evidence register and a cross-channel claims checklist. These tools turn CDP into a controlled input rather than a risky shortcut.
