Standards and reporting
GRI Reporting Consultants
A GRI consultancy brief should define the reporting claim, evidence and deliverables the organisation can inspect and retain.
What should a GRI reporting engagement deliver?
GRI 1 sets different conditions for reporting in accordance and with reference, so the engagement should identify the intended reporting basis before defining deliverables GRI 1, section 3 and with-reference requirements.
Module 01 / 03
Basis
State the intended reporting claim.
Module 02 / 03
Scope
Identify organisation, period and work included.
Module 03 / 03
Acceptance
Define the evidence and draft handover.
Read the detailed guidance and evidence
A useful consultancy brief describes what the organisation will receive and how its reviewers will inspect the result rather than asking for a GRI-certified report.
GRI’s copyright policy states that it is not an auditor, assessor, certifier or verifier of sustainability reports GRI copyright policy.
Read GRI Standards for the full system and the standards hub for other reporting destinations before commissioning a specific engagement.
The brief should state whether materiality work, data preparation, drafting, index review and repeat-cycle handover are included.
What belongs in the initial scope?
This editorial brief makes the intended work and company inputs explicit.
| Evidence question | Review approach | What to avoid |
|---|---|---|
| Reporting basis | Name the intended claim and publication context | An undefined GRI compliance project |
| Organisation | Identify entities, activities and reporting period | A group report based only on headquarters records |
| Work included | List topic review, data, narrative, index and review tasks | Assuming every task is included in drafting |
| Client input | Name source owners and approval responsibilities | Assuming the adviser can invent absent evidence |
How should material-topic work be specified?
GRI 3 identifies material topics through significant impacts, with guidance on context, impact identification, significance and prioritisation GRI 3, section 1.
Module 01 / 03
Context
Explain activities and business relationships.
Module 02 / 03
Evidence
Retain impact information and its limits.
Module 03 / 03
Conclusion
Show why topics were selected or not selected.
Read the detailed guidance and evidence
In an original fictional case, a museum-services group commissions a review of materials use and temporary installation work before drafting its first planned GRI report.
The brief requests an evidence-led topic determination rather than a workshop that ends with an unexplained ranking of popular ESG themes.
Human-rights questions may require meaningful consultation and evidence about affected groups, as described in the UN Guiding Principles, rather than only management views UN Guiding Principles 17–18.
The adviser’s deliverable should show assumptions, unresolved evidence and the company’s acceptance of the rationale, without promising a predetermined topic list.
How can the materiality deliverable be inspected?
These editorial tests distinguish a defensible topic record from a presentation summary.
| Evidence question | Review approach | What to avoid |
|---|---|---|
| Context | Relevant activities, relationships and stakeholders are described | A generic sector paragraph |
| Impact description | The affected subject and effect are identifiable | Only broad labels such as people |
| Significance | Evidence supports the applicable criteria | A score with no explanation |
| Decision | Selection and uncertainty are reviewable | A final list with no rationale |
What should the evidence workstream cover?
GRI 2 covers organisational context, activities, workers, governance, policies and engagement, so the data brief needs narrative and decision records as well as metrics GRI 2, introduction.
Module 01 / 03
Source owners
Identify who supplies each record.
Module 02 / 03
Interpretation
Explain definitions and limitations.
Module 03 / 03
Review
Record which version was accepted.
Read the detailed guidance and evidence
The fictional museum-services group holds installation-work records in project files and policy records centrally, with different people able to explain their meaning.
Its brief therefore names the contributor and reviewer for each evidence stream rather than assuming the consultant’s access to a shared folder is sufficient.
GRI 3 also asks how material topics are managed, so a topic’s policy, actions and effectiveness information need a defined evidence handover GRI 3, disclosure 3-3.
Where records are unavailable, the engagement should preserve the gap and apply the actual reporting rules rather than silently manufacturing a complete narrative.
Which deliverable boundaries should be explicit?
This editorial allocation prevents a drafting engagement from implying unperformed investigation.
| Evidence question | Review approach | What to avoid |
|---|---|---|
| Company records | State what the company supplies and explains | An assumption that all records are independently verified |
| Adviser analysis | Name the evidence and interpretation work included | A broad assurance implication |
| Data gaps | Identify missing information and proposed treatment | Unsupported zeroes or completed statuses |
| Company review | Name who accepts facts and judgements | A report approved only for style |
What should the content-index work include?
GRI 1’s content-index requirements include disclosure locations and relevant sector and omission information, making the index a substantive deliverable rather than a decorative appendix GRI 1, Requirements 6–7.
Module 01 / 03
Locations
Point to the actual published information.
Module 02 / 03
Omissions
Use permitted treatment and explanations.
Module 03 / 03
Sector review
Carry through relevant topic decisions.
Read the detailed guidance and evidence
For applicable Sector Standards, the organisation reviews likely material topics and explains relevant topics judged not material rather than assuming the sector list decides the outcome GRI 1, Requirements 3 and 7 GRI Sector Program.
The fictional museum-services brief asks the adviser to document the applicability review without forcing an unrelated Sector Standard into the project.
The acceptance test follows selected index entries into the actual draft and checks that the linked evidence supports the disclosure.
A completed index does not itself establish that every condition for an in-accordance claim has been met.
What should an index review challenge?
These editorial checks use the intended report rather than only the adviser’s workbook.
| Evidence question | Review approach | What to avoid |
|---|---|---|
| Location | Can the reviewer find the named information? | A broad link to the entire annual report |
| Required information | Does the cited passage answer the disclosure? | A heading used as evidence of content |
| Omission | Is the treatment permitted and explained? | A universal skip option |
| Update | Do references still work after the draft changes? | An index accepted before final pagination |
Which edition and publication date should the brief use?
GRI 103: Energy 2025 applies to reports or other materials published from 1 January 2027, so the planned publication date can affect the relevant source set GRI 103, effective date.
Module 01 / 03
Publication
Record when the report is intended to appear.
Module 02 / 03
Standards
Identify applicable source versions.
Module 03 / 03
Transition
Explain changes and affected deliverables.
Read the detailed guidance and evidence
GRI’s climate-and-energy project introduces revised topic content and supporting resources, which makes an edition review more useful than a generic promise to use the latest framework GRI climate and energy project.
The fictional group asks its adviser to state which versions the draft uses and to identify any review needed if publication moves into a different effective-date window.
The brief should also say whether version updates and related index revisions are included in the engagement or require a separately agreed change.
No assumption is made that every software library, older workbook or previous report already contains the newly applicable content.
What should happen if the scope changes?
This editorial change record makes extra work and reporting consequences reviewable.
| Evidence question | Review approach | What to avoid |
|---|---|---|
| Trigger | New evidence, publication timing or activities | An unexplained request to refresh the report |
| Affected work | Topics, data, narrative, index or review | Assuming only the cover date changes |
| Responsibility | Name client input and adviser deliverable | An unassigned information gap |
| Acceptance | Record the agreed revision and remaining limits | A silent change to the original scope |
How should the proposed reporting claim be reviewed?
An in-accordance claim requires all nine GRI 1 requirements, while the with-reference route has separate conditions, and neither is GRI certification GRI 1, section 3 and with-reference requirements GRI copyright policy.
Module 01 / 03
Conditions
Check the intended claim requirements.
Module 02 / 03
Evidence
Identify unresolved gaps and limitations.
Module 03 / 03
Approval
Name the company’s publication decision.
Read the detailed guidance and evidence
The fictional group should not be told that paying for advice, completing a workshop or receiving a content index automatically permits the stronger claim.
A claim review can be a defined engagement deliverable, but its scope and evidence need to be stated rather than implied by a marketing badge.
UK SRS S1 has a different financial-information purpose and its own compliance conditions, so a GRI engagement does not automatically complete another reporting basis UK SRS S1, objective and paragraphs 72–73A.
If independent assurance is sought, treat it as a separate defined question about the actual information and conclusion rather than assuming it is included in preparation.
What should be clarified in competing proposals?
This editorial proposal comparison tests equivalent work without ranking providers.
| Evidence question | Review approach | What to avoid |
|---|---|---|
| Topic assessment | Identify evidence collection and reasoning included | A workshop title as the whole scope |
| Draft and index | Name outputs, revisions and accepted source versions | An undefined compliant report |
| Review | Describe factual, technical and claim checks | An unqualified assurance implication |
| Handover | Specify usable records, instructions and exclusions | A final PDF as the only deliverable |
What should the organisation retain for the next cycle?
GRI’s taxonomy offers digital reporting routes and outputs, while GRI 1 sets the reporting conditions, so digital handover and substantive review remain distinct GRI Sustainability Taxonomy GRI 1, section 3.
Module 01 / 03
Evidence
Receive the source and decision references.
Module 02 / 03
Editable outputs
Retain narrative, index and working files.
Module 03 / 03
Instructions
Explain the next-cycle responsibilities and gaps.
Read the detailed guidance and evidence
The fictional museum-services group asks an internal reviewer to update one source reference and follow the change through the accepted topic record and draft index.
If structured digital reporting is included, the engagement should identify the promised output and relevant content version rather than implying that GRI universally requires XBRL filing.
Use GRI reporting software for the platform-specific export tests and software versus consultant for allocating the ongoing work.
The final acceptance record should state what was delivered, what remains unresolved and who owns the next cycle, without certifying future performance.
The ESG questionnaire guide turns a broad information request into defined answers, supporting records and unresolved questions.
The GRI materiality guide follows impact evidence into the selection and management of material topics on the stated GRI basis.

Frequently asked
Questions people ask
What should a GRI reporting consultant deliver?
An editorial brief can define topic reasoning, evidence work, draft disclosures, content index, version and claim review, plus an editable handover with clear exclusions.
Can a consultant provide a GRI-certified report?
GRI says it is not an auditor, assessor, certifier or verifier of sustainability reports, so that phrase should not replace the actual reporting claim.
Is a materiality workshop enough?
The engagement needs evidence and reasoning for the material-topic decisions rather than only a workshop ranking.
Does every company need a Sector Standard?
The applicability review depends on the sectors covered by published standards, and relevant sector topics still need the organisation’s own assessment.
Should publication timing be in the brief?
Yes, GRI 103’s effective date concerns reports or materials published from 1 January 2027, illustrating why the planned publication date matters.
What should be retained when the engagement ends?
An editorial handover can require editable disclosures and index, evidence references, topic reasoning, source versions, review decisions, instructions and unresolved limitations.
