To prepare this disclosure
Disclosure focus

Disclosure 2-4 requires an organisation to report any restatements of information from previous reporting periods and explain the reasons for and effects of each restatement. A restatement is a revision of information previously reported for an earlier period. Internal corrections made before information is published do not constitute a restatement under Disclosure 2-4.

Restatements can arise from an error, a change in the base period or length of the reporting period, a change in the nature of the business, a change in measurement methodology or definitions, or a disposal, merger or acquisition. An ordinary year-on-year movement, a future-only methodology change, a target update or a correction that does not affect previously reported information is not automatically a restatement.

GRI Guidance says the organisation should disclose the criteria used to determine whether a change or error is significant enough to require a restatement. The assessment should consider whether the change could influence information users’ decisions. For quantitative information, the organisation should specify the quantitative change, for example by showing the originally reported value, the restated value and the resulting absolute or percentage change.

If no restatements were made during the reporting period, a brief direct statement is sufficient. Reasons for omission are not permitted for Disclosure 2-4.

The two datapoints below are an LRA operational decomposition of the reasons and effects contained within the single requirement in Disclosure 2-4-a; they are not separate official GRI disclosures.

This LRA educational guidance supports disclosure preparation. For the exact requirements, always refer to the official GRI source.

Before you start

A quick mental checklist before you prepare this disclosure — tick each as you settle it.

Preparation

Key datapoints to prepare

Datapoint What to capture Evidence hint Owner
Prior-period restatement reasons For each revision of previously reported information, identify the affected reporting period, disclosure, table or KPI and explain the specific reason for the restatement. Previous sustainability report, restatement register, change log, methodology note and approval record. Finance, Sustainability Reporting and relevant topic data owners
Prior-period restatement impact For each restatement, explain its consequences. For quantitative information, show the originally reported value, restated value and absolute or percentage change. Original and recalculated workbook, old-to-new bridge, corrected comparative tables and cross-report consistency check. Finance, Sustainability Reporting and relevant topic data owners
+ Show GRI 2-4 sub-elements (LRA working checklist)

How to prepare it

1Compare the current draft with information published for previous reporting periods. Exclude internal corrections made before publication, ordinary year-on-year movements and future-only changes that do not revise previously reported information.
2Apply the organisation’s documented restatement criteria and record why each change or error is significant enough to require revision of previously reported information.
3For each restatement, record the affected period, disclosure, table or KPI and explain the specific reason for the revision.
4Explain the effect of each restatement. For quantitative information, capture the originally reported value, restated value and absolute or percentage change.
5Reconcile every revised comparative value across the sustainability report, ESG data book, tables, charts and GRI content index, and retain the calculation and approval trail.
6If there were no restatements, add a direct statement to that effect. Otherwise, check that every qualifying restatement has both a reason and an effect and that no reason for omission is used.
Request the data

Request the restatement register, quantitative bridge and explanations

Translate the disclosure into an internal business question — then adapt it to your organisation's own language.

Which information published for previous reporting periods has been revised, why was it restated, and what is the effect?

Send the request to Finance, Sustainability Reporting and the relevant topic data owners, such as HR, HSE, Operations, Procurement, Legal, Corporate Development or IT/Data. Ask only about revisions to previously published sustainability information; internal corrections completed before publication are not GRI 2-4 restatements.

Weak request

Please provide the GRI 2-4 restatements disclosure data.

Why it fails: This uses framework language only and does not tell the owner what practical records to pull, which period to cover, or what details are needed to explain the change and its effect.

Better request

Please send the register of revisions to information published for previous reporting periods. For each item, include the affected period and KPI, originally reported and restated information, quantitative change where relevant, specific reason, effect, recalculation method, approval trail and every publication location requiring update. Confirm directly if there were no restatements.

Formal email template

Hi [name],

We are preparing the sustainability report and need details of any information published for previous reporting periods that has since been revised. Please exclude internal corrections completed before publication.

For each restatement, please provide:
- the affected period, disclosure, table or KPI;
- the originally reported value or wording and its published location;
- the restated value or wording;
- the specific reason for the restatement;
- the qualitative effect and, for quantitative information, the absolute or percentage change;
- the recalculation methodology and supporting source;
- the approval and control record; and
- every report, data book, table, chart or index location that must be updated.

Please also confirm the restatement criteria applied. If there were no restatements, please confirm this directly.

Thanks,

Short Teams / Slack version
Hi [name] — please confirm whether any information published for previous reporting periods has been restated. For each item, send the affected period/KPI, original and restated values, reason, quantitative and qualitative effect, recalculation source, approvals and every location requiring update. Exclude corrections made before publication; if there were none, please confirm that directly. Thanks.
Industry examples
Manufacturing

Context. A plant’s annual energy figure published in the previous sustainability report was recalculated after a meter mapping error was found.

Adapted request. Please share any revisions to plant data published in previous sustainability reports, including the published location, original and restated values, quantitative change, specific reason, recalculation file, affected report locations and approval details. Exclude corrections completed before publication.

Example response. Published source: 2024 Sustainability Report, energy table; Period: FY2024; Item: electricity use; Originally reported: 1,240 MWh; Restated: 1,180 MWh; Change: −60 MWh (−4.8%); Reason: meter mapping error in the published dataset; Effect: FY2024 electricity use and intensity decrease; Recalculation: Energy close workbook v4; Approved by: Site Controller; Approval date: 12 July 2025.

Financial services

Context. A customer count published in the previous sustainability report and ESG data book was restated after a segment-classification error was identified.

Adapted request. Please provide revisions to customer information published in previous sustainability reports or ESG data books, including the affected publication, original and restated values, quantitative change, reason, effect, recalculation record and approval.

Example response. Published sources: 2024 Sustainability Report and ESG data book; Period: FY2024; Item: retail lending customer count; Originally reported: 48,200; Restated: 46,900; Change: −1,300 (−2.7%); Reason: a segment mapping error overstated the published category; Effect: the retail lending total and segment share decrease; Recalculation: control log CL-2024-18; Approved by: Reporting Lead; Approval date: 3 February 2025.

Draft your disclosure

Notes that turn data into a disclosure

LRA training templates — adapt them to your organisation, and check the official source before sign-off.

Method note

State which earlier reporting periods were updated, explain the basis used to identify those revisions, and describe the approach taken to calculate their impact.

Context note

Explain what the revised figures mean for the reported story, including how the updates change the reader’s understanding of the earlier periods.

Fluctuation statement

Apply the documented restatement criteria to decide whether a change or error is significant enough to influence information users’ decisions. This is GRI Guidance, not a test based on whether a change seems exceptional or relates to a material topic. For quantitative information, show the quantitative change.

Common reporting gaps

A restated value silently replaces the value published for the previous reporting period.The reason is stated, but the effect of the restatement is not explained.The restated value is shown without the originally reported value, so the scale of the change is unclear.A quantitative restatement does not specify the quantitative change.A generic phrase such as ‘methodology was updated’ does not explain what changed or why prior information was affected.The affected reporting periods, disclosures, tables or KPIs are not identified.Different restated values appear in different parts of the reporting suite.The organisation does not disclose its criteria for deciding when a revision is significant enough to require restatement.An internal correction made before publication is incorrectly labelled as a GRI 2-4 restatement.Nothing is stated when no restatements were made during the reporting period.
Common gaps

Mistakes to avoid when collecting the data

Wrong owner asked
The team chases the disclosure lead instead of the person who actually changed the figures, so the reason and the impact are collected from hearsay rather than the source team.
Framework language used too early
People ask for answers in reporting jargon instead of the business terms used by finance, HR, operations or the data owner, which slows down retrieval and creates mismatches.
Published information not identified
The team does not identify the previous sustainability report, period, disclosure, table or KPI that contained the information, so an internal adjustment can be mistaken for a GRI 2-4 restatement.

Where judgement is often needed

Acquisition or disposal
A transaction can lead to a restatement but does not do so automatically. Determine whether previously reported information is recalculated, which periods and indicators are affected, whether the change is retrospective and whether comparable recalculation is possible. Consider reporting entities and consolidation under Disclosure 2-2.
Estimate replaced by actual data
Replacing an estimate does not automatically require restatement. Apply the documented criteria to determine whether the revision to previously reported information is significant enough to influence information users’ decisions.
System or methodology change
Distinguish a future-only method change from retrospective recalculation, correction of an error, improved source data, or a changed definition or factor. GRI 2-4 applies when the change revises information previously reported for an earlier period.

Examples

Illustrative examples

Synthetic, written by LRA — not from a company report, not text from any standard.

Illustrative (synthetic) example — Consumer goods manufacturing

The original 2024 figures had been reported in the organisation’s previous sustainability report. In the 2025 report, they were restated after a review found that one site had been excluded from the 2024 consolidation set.

• Total workforce — originally reported: 4,800; restated: 5,000; change: +200 (+4.2%).

• Recordable injuries — originally reported: 24; restated: 25; change: +1 (+4.2%).

Reason: a reporting-boundary error excluded one site from the published 2024 dataset.

Effect: the restatement increases both 2024 indicators; current-year figures are unchanged.

This example establishes that the information was previously published, gives a specific reason and shows the quantitative effect for each affected indicator.

Illustrative (synthetic) example — Retail logistics

The 2024 values below were published in the previous sustainability report and are restated after meter-based data replaced an estimate for one distribution centre.

• Total electricity — originally reported: 12,000 MWh; restated: 11,400 MWh; change: −600 MWh (−5.0%).

• Renewable electricity quantity — unchanged at 4,800 MWh.

• Renewable electricity share — originally reported: 40%; restated: 42% (42.1% before rounding); change: +2 percentage points.

Reason: more complete meter data reduced the total-electricity denominator while renewable electricity remained unchanged.

Effect: total electricity decreased and the renewable share increased.

This example makes the denominator logic explicit and distinguishes a percentage-point change from a percentage change.

Illustrative (synthetic) example — no restatements

The organisation made no restatements of information reported for previous reporting periods.

Where no restatements were made, GRI Guidance says a brief direct statement is sufficient.

How companies report GRI 2-4 in practice

Examples of full and partial reporting practice. These are evidence-led reviews, not exact disclosure templates to copy.

Tanla Platforms Limited
Software and Services · India · 2025
Open report →
Tanla’s GRI 2-4 statement says that reasons and effects appear under the relevant BRSR principles (p.194). One located example states that FY2024 water data were restated ‘based on evaluation’ and presents revised values (p.222). The reason is not specific, and the cited page does not show the originally reported values or quantitative change, so both reason and effect are assessed as partial.
Sims Limited
Solid Waste Management Utilities · Australia · 2025
Open report →
Sims describes multiple restatements affecting Scope 1, Scope 2, emissions to air, intensity measures and Scope 3 categories. It identifies periods and gives specific reasons including the BSC acquisition, classification correction, additional data, new emissions software and methodology or input changes (pp.47–48; another waste restatement appears on p.53). Directional effects are given for some items, such as lower APAC and higher North America market emissions, but an original-to-restated quantitative bridge is not shown for every restatement in the overview, so effect coverage is partial.
Kakao Corp.
Media · South Korea · 2024
Open report →
Kakao’s emissions table explains that 2022 and 2023 Scope 3 values were recalculated after calculation boundaries were expanded and methodology refined in 2024 (p.144). The table presents recalculated values and notes a directional decrease for a separate emissions-intensity method change, but it does not show the originally reported values or a quantitative old-to-new bridge. Reason coverage is therefore covered and effect coverage partial.

Scenarios to work through

A workforce figure is corrected in the current report’s working file before the report is published. The incorrect draft value has never appeared in published sustainability information.

QIs this a restatement under GRI 2-4?
Reveal model answer →

A prior-year emissions total was recalculated after a data source was replaced with a more complete one. The revised total is lower than the figure previously published, and the reporting team is deciding whether to mention only the new number.

QWhat should the preparer include alongside the updated figure?
Reveal model answer →

A sustainability metric for the prior year was corrected after a calculation error was found. The team has the revised value and a short note about the error, but has not yet drafted any explanation of how the correction affects the published trend.

QWhat decision should the preparer make before sign-off?
Reveal model answer →

The reporting team applies its documented criteria and confirms that no information published for previous reporting periods was restated during the year.

QWhat should the GRI 2-4 disclosure say?
