1. Basis of preparation and jurisdiction

The ISSB standards become law only where a jurisdiction adopts them, and most jurisdictions adopt them with modifications, phase-ins or a different effective date. Start by recording the instrument that makes reporting mandatory for the entity, or record that reporting is voluntary and why. Where a group reports in several jurisdictions, list each regime, because the same group may face a mandatory climate standard in one market and voluntary use in another.

The IFRS Foundation reported in early 2026 that more than 40 jurisdictions had decided to use the ISSB standards or were taking steps to introduce them. The table below is a starting point only. Each row was checked against secondary sources in October 2026 and must be confirmed against the official instrument before you rely on it.

Example: Corvid Commerce Group plc is listed in London, so its climate disclosures are already required: the FCA listing rules require a statement of consistency with the TCFD recommendations in the annual financial report, on a comply-or-explain basis, and Companies Act 2006 sections 414CA and 414CB require climate-related financial disclosures in the strategic report of traded companies with more than 500 employees (Corvid has 685). It prepares the full report under IFRS S1 and IFRS S2 voluntarily, because its revolving credit facility includes a sustainability-linked margin, its two largest equity investors ask for ISSB-based reporting, and it wants to be ready if the FCA makes UK SRS reporting a listing requirement. Because IFRS S2 covers the TCFD recommendations, one climate section serves both the mandatory and the voluntary disclosures; keep a mapping so the TCFD statement can point to it. As a foreign private issuer, Corvid also files Form 20-F with the SEC; the SEC climate disclosure rules adopted in 2024 were stayed and the SEC ended its defence of them in 2025, so no US climate rule is assumed here (check the current position).

2. Sustainability-related risks and opportunities

The rest of the report depends on this list. Assemble it from the enterprise risk register, strategy documents, investor questions, industry sources the standards direct you to consider, and, where the group also reports under ESRS, the financial materiality results of the double materiality assessment. Record for each item the time horizon, the part of the value chain it arises in and the business area that owns it.

Describe each risk or opportunity as a mechanism with a financial consequence. A good entry says what changes, through which channel, and how the change would show up in revenue, cost, asset values, liabilities or financing terms. Distinguish physical climate risks (acute events and chronic shifts) from transition risks (policy, technology, market and reputation), because the strategy and metrics sections treat them differently.

Define the horizons used and link them to planning cycles: Example: short term is under 2 years (budget and rolling forecast), medium term is 2 to 5 years (strategic plan), long term is more than 5 years (useful lives of capitalised software and data-centre commitments).

3. Governance

References to check: IFRS S1 paragraphs 26 and 27; IFRS S2 paragraphs 5 to 7.

Write this section from the governance documents the entity already has: board and committee terms of reference, the schedule of matters reserved for the board, management committee charters, job descriptions and remuneration policies. Describe who is responsible, how they are informed, how often, and what they did with the information during the period. Show the skills available to the board, and how the board obtains expertise it does not have, such as external briefings or advisers.

Evidence matters more than wording. A reader should be able to see that the board discussed the transition plan, approved targets, and challenged management on progress, with dates. Where executive remuneration is linked to sustainability metrics, state the metric and its weight in the incentive plan, and cross-refer to the remuneration report rather than repeating it.

4. Strategy

References to check: IFRS S1 paragraphs 28 to 42; IFRS S2 paragraphs 8 to 23, including the climate resilience paragraphs and the scenario analysis guidance in the standard.

Build this section from the strategic plan and the budget. For each risk and opportunity in section 2, explain where it sits in the business model, what management is doing about it and what it costs. Separate effects already visible in the current period from effects anticipated later, and give amounts or ranges where they can be estimated. Where you cannot give a quantitative estimate, say why, and what would allow you to give one in future.

Scenario analysis for climate resilience should be proportionate to the entity's exposure and resources. A software and commerce group with modest physical assets may begin with qualitative scenarios supported by a small number of quantified sensitivities, and increase depth as data improves. Record the scenarios, their sources, key assumptions, time horizons and the results, and explain how the results informed the strategy.

Transition plan summary: [targets, levers, dependencies, capital allocated, and how progress is reported]. Example: Corvid's transition plan targets a 42% reduction in Scope 3 emissions intensity per EUR million of revenue by 2030 against FY2026, through supplier engagement on hardware, carrier mix and hosting region choice. The plan relies on supplier-specific emission factors replacing spend-based estimates, which will itself change the baseline; the plan explains that recalculation policy in section 7.

5. Risk management

References to check: IFRS S1 paragraphs 43 and 44; IFRS S2 paragraphs 24 to 26.

Describe the process as it actually runs. State which inputs are used (internal data, industry sources, scenario analysis, stakeholder information), how likelihood and magnitude are assessed, how sustainability-related risks are compared with other risks, and who decides on the response. Show where the process sits in the enterprise risk management cycle and whether it changed during the period.

Opportunities follow a different path in most organisations: they are identified through strategy and product planning rather than through the risk register. Say so if that is the case, and explain how they are tracked to a decision.

6. Metrics and targets

References to check: IFRS S1 paragraphs 45 to 53; IFRS S2 paragraphs 27 to 37, including the cross-industry metric categories and the target paragraphs; for industry-based metrics, the SASB Standards and the Industry-based Guidance on Implementing IFRS S2 (names only).

Use a metric register so every number in the report has one definition, one owner and one data source. For industry-based metrics, list the industries considered and the metric codes selected, and explain why others were not applicable. Where a metric comes from the financial statements, use the same amounts and cross-refer. Where a target is set, state the base year, the metric, the target period, interim milestones and whether the target was validated by a third party.

Check: MET-005 equals (310 + 620 + 30,980) / 140 = 31,910 / 140 = 227.9 tCO2e per EUR million of FY2026 revenue (EUR 140 million).

Check: 227.9 x (1 - 0.42) = 132.2.

7. Greenhouse gas inventory

References to check: IFRS S2 paragraph 29 and the measurement guidance in the standard, together with the amendments issued 2025-12-11 (effective 2027-01-01). Measurement method: GHG Protocol Corporate Accounting and Reporting Standard (2004 revised edition) and Corporate Value Chain (Scope 3) Standard; check for revisions in progress at the GHG Protocol.

Describe the boundary approach (operational control, financial control or equity share), the consolidation of subsidiaries, the gases included, the emission factor sources and vintages, the share of data that is estimated, and the recalculation policy for the base year. For Scope 3, list all fifteen categories, state which are relevant and included, and explain exclusions. Distinguish primary supplier data from spend-based or average-data estimates, because users judge the reliability of Scope 3 by that mix.

Check: 16,000 + 2,400 + 260 + 6,900 + 180 + 940 + 1,100 + 3,200 = 30,980. Capitalised hardware (the PP&E classes in Fixed Asset Register, finance/fixed-asset-register) belongs in category 2, not category 1; the point-of-sale terminals are the POS class in that register, owned by the group and rented to subscription customers, which is why their use-phase energy is in category 13 rather than category 11.

Base-year recalculation policy: [threshold and triggers]. Example: Corvid recalculates the base year when structural changes, methodology changes or discovered errors change base-year emissions by 5% or more, individually or together. The planned switch from spend-based to supplier-specific factors for hardware is expected to trigger a recalculation in FY2027.

8. Connectivity with the financial statements

References to check: IFRS S1 paragraphs 21 to 24 (connected information).

Connectivity is the feature users value most and preparers most often miss. Walk through each significant assumption in the financial statements that could be affected by a sustainability-related risk (cash-flow forecasts in impairment tests, useful lives, provisions, going concern, expected credit losses on receivables) and record whether it is consistent with the strategy section. Where they differ for a good reason, explain the difference rather than leaving users to find it.

9. Judgements, estimates and errors

References to check: IFRS S1 paragraphs 74 to 86.

List the judgements that most affect the report: which risks and opportunities were identified, which industry metrics were selected, which boundary was used for emissions, how financial effects were estimated. For each metric with significant measurement uncertainty, identify the source of uncertainty and the assumptions made. Keep a log of prior-period errors found during the year, their correction and whether comparatives were restated.

Check: JDG-001 uses about 14,500 tCO2e of hardware-related emissions within categories 1 and 2 (an estimate within their combined 18,400: 16,000 + 2,400); 20% of 14,500 is 2,900. JDG-002: 20% of 3,200 is 640.

10. Data, controls and assurance

Treat the report as a reporting process with controls. For each metric, record the source system, the extraction and calculation steps, the reviewer and the evidence of review. Use the same control vocabulary as for financial reporting so the internal audit function and the external assurance provider can test it. Where assurance is obtained, state the standard (ISSA 5000 for periods beginning on or after 2026-12-15, or the national standard), the level of assurance and the scope.

Cross-reference the control documentation to the Risk Control Matrix (compliance/risk-control-matrix) and the testing to the Control Testing Workpaper (compliance/control-testing-workpaper).

11. Statement of compliance and approval

References to check: IFRS S1 paragraphs 72 and 73; the transition appendices of IFRS S1 and IFRS S2; jurisdictional rules on compliance statements (for example, UK SRS treats compliance with S1 differently when only climate is reported).

Draft the statement in your own words after legal and audit review, naming the standards (and jurisdictional version), the period, and every transition relief used. Record the approval by the governance body.
