Standards and reporting
Sustainability reporting checklist
A sustainability reporting checklist should move a team from an identified reporting basis to a reviewed evidence pack, with an owner, output and unresolved decision at each stage.
What should you decide before collecting data?
Identify the reporting obligation and selected framework first, because publication of a standard does not itself impose a duty on every organisation DBT UK SRS guidance.
Module 01 / 04
Purpose
Record why the report is being prepared and who will use it.
Module 02 / 04
Applicability
Identify any legal or contractual reporting route requiring separate analysis.
Module 03 / 04
Framework
Name the standards and versions the work will follow.
Module 04 / 04
Deliverable
Define the publication, internal pack and any recipient-specific output.
Read the detailed guidance and evidence
A software questionnaire can collect data without resolving any of these decisions.
Use the standards overview and mandatory-reporting guide before treating a task list as a legal determination.
What are the main preparation gates?
Use explicit outputs and review decisions so a completed task has evidence behind its status.
| Gate | Output | Decision before moving on |
|---|---|---|
| Basis agreed | Obligation and standards note | Are the audience and reporting claim clear? |
| Boundary agreed | Entity, activity and period map | Do the relevant populations reconcile? |
| Assessment reviewed | Materiality and applicability record | Do requested fields follow the selected basis? |
| Evidence prepared | Dictionary, records and calculations | Are missing data and estimates visible? |
| Report reviewed | Draft, index and issue log | Are claims supported and limitations explained? |
How should the reporting boundary be checked?
Document the entity and its relationship to other reporting information, with UK SRS disclosures using the same reporting entity as the financial statements paragraph 20.
Module 01 / 04
Group
Identify parent, subsidiaries and consolidation treatment.
Module 02 / 04
Activities
Map operations, value-chain activities and metric-specific populations.
Module 03 / 04
Period
Retain the reporting dates and any differences in measurement periods.
Module 04 / 04
Change
Record acquisitions, disposals, new sites and altered definitions.
Read the detailed guidance and evidence
One organisational boundary does not remove the need to explain how individual measures cover different activities or populations.
For emissions, use the Corporate Standard to investigate the inventory approach rather than assuming that all reporting boundaries are identical.
Which framework-specific checks belong beside the checklist?
Keep the legal reporting route and the selected framework’s content requirements visible instead of merging them into one universal test.
| Workstream | Check | Detailed guide |
|---|---|---|
| UK SRS | Core content, material information and general requirements | UK SRS S1 |
| GRI | Impact assessment and the chosen statement-of-use conditions | GRI Standards |
| ESRS | Version, double materiality, conditions and reliefs | ESRS datapoints |
| SECR | Quoted, unquoted or LLP route and applicable disclosures | SECR report template |
| Voluntary Standard | Selected module and applicable information | VSME reporting |
What should a materiality task produce?
Retain the reasoning and information-selection decisions required by the chosen basis, rather than merely a coloured matrix UK SRS S1 materiality GRI 3 ESRS 1 chapter 3.
Module 01 / 04
Matter
Describe the actual impact, risk or opportunity and affected activities.
Module 02 / 04
Evidence
Identify source information and relevant stakeholder or business evidence.
Module 03 / 04
Reasoning
Apply the appropriate assessment criteria and explain the judgement.
Module 04 / 04
Disclosure
Connect the conclusion to the information selected for reporting.
Read the detailed guidance and evidence
The financial materiality guide and double-materiality template provide separate working approaches.
The checklist tracks whether the assessment is reviewable without inventing a universal scoring threshold.
What must a data request specify?
Give each request a definition, population and source requirement before asking an owner to populate a number.
| Request field | Useful instruction | Failure prevented |
|---|---|---|
| Metric and unit | Define the quantity and measurement unit | Different measures collected under the same label |
| Population and period | Name included entities, activities and dates | A site or month silently excluded |
| Source and method | Identify records, transformations and estimates | A total that cannot be reproduced |
| Owner and review | Allocate preparation and checking responsibility | An unanswered request described as complete |
| Status and limitations | Distinguish measured, estimated, missing and not applicable | A blank converted to zero |
What should calculation review cover?
Check quantities, factors, units and classifications, with relevant conversion-factor guidance applied before aggregation DESNZ publication.
Module 01 / 04
Quantity
Reconcile the source population and explain estimates.
Module 02 / 04
Factor
Retain the exact annual publication, selected row and unit.
Module 03 / 04
Arithmetic
Reproduce a sample calculation and output conversion.
Module 04 / 04
Aggregation
Avoid mixing different boundaries or double-counting components.
Read the detailed guidance and evidence
The conversion factors guide explains the activity-year rule and the distinction between missing factors and zero.
For the climate disclosures being prepared, check the relevant emissions requirements rather than assuming a carbon dashboard contains every required narrative UK SRS S2.
How should an unresolved issue be tracked?
This fictional data-control example shows why an open issue must remain visible even when a report deadline is approaching.
| Issue field | Fictional entry | Review implication |
|---|---|---|
| Issue | Warehouse electricity records missing for two months | The annual quantity is not fully measured |
| Owner | Operations preparer; finance reviewer | Roles are illustrative rather than named real staff |
| Proposed response | Obtain records or document an appropriate estimate | No invented value is inserted |
| Affected outputs | Energy total, emissions calculation and related narrative | Identify every dependent output |
| Closure evidence | Reconciliation and reviewer decision | Changing the status label alone does not resolve the gap |
How should the report draft be checked against evidence?
Connect the narrative with the reviewed data and decisions, with UK SRS requiring understandable connections within disclosures and to related financial reports paragraphs 21–24.
Module 01 / 04
Governance
Match described responsibilities to actual oversight records.
Module 02 / 04
Actions
Separate measures taken from proposals and ambitions.
Module 03 / 04
Metrics
Use the reviewed definitions, quantities and limitations.
Module 04 / 04
Connections
Explain links between risks, plans, resources and results.
Read the detailed guidance and evidence
The sustainability report template provides an outline for organising the narrative.
Check that a rewritten paragraph has not expanded a site-specific measurement into an unsupported group-wide claim.
Which comparisons deserve a separate review?
Check periods, definitions and methods before interpreting movements, with comparative requirements determined by the reporting basis UK SRS S1 paragraphs 70–71.
| Comparison | Review question |
|---|---|
| Previous year | Are the period, boundary and metric definition comparable? |
| Target baseline | Does the target cover the same activities as the inventory? |
| Financial information | Are related data and assumptions consistent where required? |
| Other reporting framework | Are reused numbers based on equivalent definitions? |
| Factor update | Does a method or data change explain part of the movement? |
How should assurance readiness fit the checklist?
Prepare a clear evidence pack and establish any engagement’s scope separately from internal approval.
Module 01 / 04
Information
Identify the exact disclosures proposed for assurance.
Module 02 / 04
Criteria
Name the criteria against which that information would be assessed.
Module 03 / 04
Evidence
Retain records, estimates, calculations and review decisions.
Module 04 / 04
Conclusion
Read the actual provider’s report before describing what was assured.
Read the detailed guidance and evidence
An internal readiness review is not itself an external assurance conclusion.
The sustainability assurance guide explains engagement scope and terminology, while GRI 2 disclosure 2-5 addresses relevant external-assurance reporting information.
What should be checked before publication?
Review the exact claim, required index and information locations before releasing the final pack UK SRS S1 statement of compliance GRI 1 statements of use.
| Release check | Evidence |
|---|---|
| Reporting basis | The stated basis matches the actual completed assessment |
| Index and links | Selected disclosures resolve to the correct final locations |
| Claims and limitations | Qualifications and gaps remain visible in the approved version |
| Approval | The appropriate reviewer has considered outstanding decisions |
| Archive | The report and supporting evidence can be retrieved together |
What makes the checklist useful next year?
Retain decisions and changes so the next reporting cycle starts from a reviewed record rather than an unexplained spreadsheet.
Module 01 / 04
Version
Save the final report and exact working-file versions.
Module 02 / 04
Ownership
Record who maintains each dataset and judgement.
Module 03 / 04
Change log
Explain updates to boundaries, methods and source records.
Module 04 / 04
Open issues
Carry forward unresolved limitations with an owner.
Read the detailed guidance and evidence
When procuring reporting software, test whether the pack can be exported without losing definitions and evidence links.
A reporting consultancy brief should specify the decision log and usable handover alongside the draft report.

Frequently asked
Questions people ask
Is this a statutory sustainability reporting checklist?
No, it is an original editorial preparation workflow that needs to be adapted to the actual reporting basis and obligations.
Should we collect every possible ESG metric?
Requests should follow the selected framework, relevant matters and applicable requirements rather than an unfiltered list of fields.
Can a missing value be recorded as zero?
A missing quantity and a measured zero are different statuses and need to remain distinguishable.
Does completion mean the report is compliant?
Task completion needs evidence and review, while the final reporting claim requires a separate assessment of applicable requirements.
When should software be selected?
A defined reporting basis, data dictionary and handover brief make the platform demonstration meaningful.
Does internal review count as external assurance?
Internal preparation or readiness review is separate from an assurance engagement and its actual scope and conclusion.
