Applicable from FY2027

This revised ESRS edition applies from reporting year 2027. For reporting years 2024–2026, use the ESRS 2023 edition.

Description of the Processes to Identify and Assess Material Impacts, Risks and Opportunities

IRO-1 · mandatory · narrative disclosure

This disclosure asks an organisation to explain how it goes about finding and assessing the impacts, risks and opportunities that matter for sustainability reporting. In practice, that means describing the process it uses to identify what is material, how it judges significance, and how it keeps that process up to date. The focus is on the method, not just the final list of topics: readers should be able to understand how the organisation reached its conclusions.

Disclosure focus

The practical emphasis is on whether the process is broad and systematic enough to cover the organisation’s real footprint, rather than only a few well-known or flagship sites. A useful explanation would show how the organisation looks across its own operations and, where relevant, its wider value chain, and how it makes sure important issues are not missed because they sit outside the most visible parts of the business.

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

Prepare

What to collect before drafting

Tick each field as the evidence lands. Owners are the teams that usually hold the source files.

  • Assessment method

    Sustainability / risk team

    Describe the approach used to assess the matter, including the overall method and how it is applied in practice.

    Evidence Method note, assessment framework, internal guidance, or working paper showing the approach used.

    Watch for Method description does not match the actual assessment process used in the source working papers.

  • Assessment steps

    Sustainability / risk team

    Set out the sequence of actions followed when carrying out the assessment, in the order they are actually done.

    Evidence Process map, workflow note, or assessment checklist with the steps recorded.

    Watch for Step order is taken from a template and does not reflect the real decision path used by the team.

  • Decision cut-offs

    Sustainability / risk team

    Record the cut-off points or decision points used to decide what is included, excluded, or escalated.

    Evidence Scoring guide, decision matrix, or internal threshold note used in the assessment.

    Watch for Cut-offs are copied from policy but do not align to the thresholds actually used in the assessment file.

  • Working assumptions

    Sustainability / risk team

    List the assumptions applied when making the assessment, including any simplifying judgments or estimates.

    Evidence Assumptions log, model note, or working paper showing the assumptions used.

    Watch for Assumptions are not the same as those used in the underlying analysis or model.

  • Assessment inputs

    Sustainability / risk team

    Identify the source information fed into the assessment, including internal and external data used to reach the result.

    Evidence Source data list, data pack, or model input register linking inputs to their origin.

    Watch for Inputs do not reconcile to the source system or a key input set is missing from the assessment pack.

  • Impact severity basis

    Sustainability / risk team

    Explain how seriousness is judged, including the criteria used to rate how severe an impact could be or is.

    Evidence Severity rubric, impact scoring guide, or risk methodology note.

    Watch for Severity is scored using a different scale or definition than the one set out in the assessment method.

  • Impact likelihood basis

    Sustainability / risk team

    Explain how chance is judged, including the criteria used to rate how probable an impact could be or is.

    Evidence Likelihood rubric, probability guide, or risk methodology note.

    Watch for Likelihood is rated on a scale that does not match the documented assessment criteria.

  • Priority setting approach

    Sustainability / risk team

    Describe how the organisation decides which matters are treated first, including the logic used to rank them.

    Evidence Prioritisation matrix, ranking method, or decision note showing how priorities were set.

    Watch for Priority ranking is based on a different rule set from the one used in the underlying review.

  • High-risk focus areas

    Sustainability / risk team

    Identify the areas where risk is especially elevated and therefore needs closer attention.

    Evidence Risk register, hotspot analysis, or issue log highlighting the elevated-risk areas.

    Watch for High-risk areas omit a known hotspot or use a different scope from the risk review.

  • Due diligence input

    Sustainability / risk team

    State whether due diligence work informed the assessment.

    Evidence Yes/no sign-off in the assessment file, due diligence memo, or review checklist.

    Watch for The yes/no flag is set without checking the due diligence file that actually fed the assessment.

  • Consulted stakeholders

    Sustainability / stakeholder engagement team

    List the stakeholder groups or parties that were consulted during the process.

    Evidence Consultation log, meeting record, or engagement tracker naming the parties consulted.

    Watch for Consulted parties are taken from a summary list and a stakeholder group from the process is left out.

  • Outside specialists consulted

    Sustainability / legal / technical team

    List any external specialists or advisers brought in to support the assessment.

    Evidence Advisor engagement record, expert report, or procurement file showing external input.

    Watch for External experts are omitted because the record only captures internal reviewers.

  • Use of input

    Sustainability / risk team

    Explain how the consultation or expert input affected the assessment, decision, or final wording.

    Evidence Decision memo, response log, or annotated working paper showing how input was used.

    Watch for Input is recorded as received but the file does not show how it changed the assessment outcome.

  • Identified changes

    Sustainability reporting / control owner

    Describe any changes that were identified in the review period, including what changed and where.

    Evidence Change log, revision tracker, or comparison note between reporting periods.

    Watch for Changes are captured from the final report only and miss items identified earlier in the review cycle.

  • Change explanation

    Sustainability reporting / control owner

    Explain why the identified change happened, using the actual driver rather than a generic label.

    Evidence Change log commentary, issue investigation note, or management explanation.

    Watch for The reason given does not match the underlying driver recorded in the change log or source analysis.

Before you start

  • Which parts of the business, value chain and time period are you actually covering in this review?
  • What yardstick will you use to judge seriousness, chance of happening and which items get pushed up the list?
  • Which sources will you rely on, and can each point be traced back to a named record or dataset?
  • What assumptions, cut-offs and input data are you using, and are they the same ones used elsewhere in your reporting pack?
  • Have you brought in any internal or external views, and if so, how will you use them in the assessment?
  • If anything has changed since the last cycle, can you explain what changed and why it changed?
+ Show IRO-1 sub-elements (LRA working checklist)

How to prepare it

Set the boundary first: state which parts of the business, value chain, time period, and reporting population your process covers, so the reader can see what was in scope for the assessment.
Define your working rules: explain the method you used, the decision path you followed, the cut-offs or trigger points you applied, the assumptions you relied on, and the information sources you drew on.
Explain how you judged importance: set out the criteria you used for seriousness and for chance of occurrence, then describe how those criteria fed into your ranking or sorting of matters, including any areas you treated as especially sensitive or exposed.
Record who informed the process: note whether the assessment drew on due diligence work, identify the internal or external parties you consulted, and explain how their input shaped the outcome.
Compile the output in the form needed: bring together the figures, narrative explanations, or both, using the evidence and working papers that support the conclusions and the way the assessment was carried out.
Document what changed and why, then check the final wording against the official source so any exclusions, updates, or methodological shifts are clear and the disclosure stays aligned with the underlying requirement.

Request the data

Request the impact-and-risk assessment process evidence

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

How do we currently identify, screen, prioritise and update the sustainability topics that matter most to the business?

Use your organisation’s own names for the process, committees, scorecards and review cycles first, then map them to the reporting disclosure. Keep the request in the language people actually use internally, and check the source material before sign-off.

Weak request

Please provide the ESRS 2:IRO-1 materiality assessment methodology, decision steps, thresholds, assumptions, inputs, severity criteria, likelihood criteria, prioritisation approach, heightened-risk areas, due diligence input, stakeholders consulted, external experts consulted, how input was used, changes identified and reason for change.

Why it fails: It uses framework language only, which can be hard for the business owner to recognise. It also bundles many concepts into one long ask, so the recipient may not know which internal documents or systems to check. That makes it slower to answer and easier to miss evidence.

Better request

Please share the documents and notes that show how your team reviews and ranks the sustainability topics that matter most for [period]. I need the process steps, the rules used to separate higher-priority items, the main inputs, the criteria used to judge seriousness and chance of occurrence, any higher-risk areas, who was consulted, how their input changed the outcome, and what changed since the last cycle. A short table plus source files or links is fine.

Industry examples

Manufacturing

Context. A group with several plants wants evidence from operations and EHS on how site-level issues are screened and escalated into the group review.

Adapted request. Please send the process note, workshop pack and risk log extracts that show how plant issues are screened, scored and escalated for [period]. Include the cut-offs used, the criteria for judging seriousness and chance of occurrence, the sites or lines treated as higher risk, and any changes made after consultation with site managers or external specialists.

Example response. Returned pack includes a process note, a scoring sheet, a list of plants reviewed, the escalation threshold, and a change log showing two new site risks added after the annual workshop.

Retail

Context. A consumer business wants evidence from strategy, risk and procurement on how supplier and customer issues are prioritised across the chain.

Adapted request. Please share the review pack that shows how customer, supplier and store issues were identified and ranked for [period]. Include the method used, the decision rules, the main data sources, the seriousness and chance criteria, any supplier regions or product lines treated as higher risk, and how input from procurement or external advisers was used.

Example response. Returned pack includes a workshop deck, a risk register extract, supplier survey results, a prioritisation matrix and notes showing that two supplier regions were moved into the higher-risk group after external input.

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

Method note

We can describe the basis of the assessment by setting out the method used, the steps followed to reach decisions, the cut-offs applied, the assumptions made, and the main inputs relied on.

Context note

This section can explain what the figures mean in practice by linking the assessment criteria, the ranking approach, any outside input, and the areas identified as needing closer attention.

Fluctuation statement

If the numbers moved during the period, we can explain that by pointing to the changes identified, the reasons behind them where known, and any shift in the inputs, thresholds, or external input used.

Check

For each claim, check the evidence

  • We used our own process notes to show how we mapped the figure to the parts of the business we actually reviewed, including relevant links in the supply chain and customer side where they mattered.

    Risk An assurer may test whether the coverage was genuinely broad enough, or whether important parts of the business or value chain were left out without a clear reason.

    Evidence to check Scoping papers, boundary memos, process maps, and working files showing which entities, sites, activities and value-chain stages were included or excluded, with reasons for exclusions.

  • We can point to the step-by-step review trail we followed, from initial screening through to the final judgement on what was included in the report.

    Risk An assurer may look for gaps in the decision trail, unclear sequencing, or evidence that the judgement was made informally rather than through a defined process.

    Evidence to check Assessment workflow, meeting notes, decision logs, review checklists, sign-off records, and version history showing the sequence of decisions.

  • Our files show how we extended the review beyond our direct operations to the wider chain where that was relevant to the assessment.

    Risk An assurer may challenge whether the disclosed scope really covered upstream and downstream matters, or whether the boundary was set too narrowly.

    Evidence to check Boundary methodology, scope rationale, supplier/customer screening records, and any maps or matrices showing how the wider chain was considered.

  • We kept a record of the methods, source data, assumptions and cut-offs we relied on when deciding what was material.

    Risk An assurer may probe whether the approach was sufficiently robust, whether assumptions were arbitrary, or whether thresholds were set to steer the outcome.

    Evidence to check Methodology paper, calculation sheets, assumption register, threshold settings, sensitivity checks, and approvals for any judgement calls.

  • We can show when the last refresh of the assessment was completed.

    Risk An assurer may question whether the date is current, whether the assessment has been updated after major events, or whether the reporting period is misstated.

    Evidence to check Project timetable, dated sign-off, board or committee papers, and the final version control record showing the update date.

  • The wording in the report reflects our own assessment work rather than a copied template.

    Risk An assurer may test whether the narrative is generic, recycled from another report, or too vague to demonstrate the entity’s actual process.

    Evidence to check Drafts with tracked changes, internal review comments, source working papers, and evidence that the narrative was tailored to the entity’s own process.

Evidence pack to prepare

Common reporting gaps

  • The information is presented without a date or as-at point.
  • The scope or boundary of the statement is left undefined.
  • Key terms are used inconsistently across the report.
  • Material changes since the previous period are not disclosed.
  • Assertions are made without supporting detail or a source record.
  • Boilerplate is used that does not actually answer what is asked.

Where drafts go wrong

Mistakes to avoid and where judgement is needed

The left column is what preparers get wrong while collecting; the right column is where you will have to make and explain a judgement.

Mistakes to avoid

  • Wrong ownerThe team asks the sustainability lead for process details that sit with operations, risk, legal, or procurement, so the evidence comes from the wrong part of the business.
  • Framework language onlyPeople ask for answers in ESRS-style terms instead of the organisation’s own working language, which produces vague responses that staff cannot verify against source records.
  • Scope left unclearThe data request does not state which business units, sites, or activities are in scope, so different teams send mixed coverage that cannot be reconciled.
  • Wrong time basisOne team uses the reporting year while another uses a later cut-off or an earlier snapshot, so the collected evidence does not line up to the same period.
+ Show 4 more

Judgement needed

  • Setting the group boundary after a buy-in or saleUse the reporting perimeter that matches the period you are explaining, and if a purchase or disposal changes what sits inside the business, say when that change was brought into the assessment and how it affected the process steps and any updated findings.
  • Reconciling different local definitions across countriesWhere local rules or operating labels differ by country, choose one internal basis for the assessment, explain the mapping from local terms to that basis, and note any places where the comparison is not exact.
  • Deciding how to treat people or sites near the edge of scopeIf a worker group, supplier tier, site, customer segment, or community sits close to the boundary, state the rule used to include or exclude it and explain why that rule was applied consistently.
  • Choosing the cut-off date for the assessmentIf the process uses a year-end snapshot, an average over the period, or another timing point, disclose that choice and make clear how it affects what was seen as significant in the period.

Examples

How it reads on the page

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

Illustrative (synthetic) example — Food processing

Illustrative only. We first mapped the issues most likely to affect our business model and supply chain, then screened them using a simple scoring method that combined scale of effect, how hard it would be to put right, and how likely it was to happen. We treated matters as higher priority where the score crossed our internal cut-off, where our assumptions were more conservative, or where the issue sat in a known higher-risk part of the business; for this exercise, we used 18 internal and external data inputs, consulted 12 people from operations, procurement, HR and worker representatives, and brought in 2 outside specialists, whose views helped us refine the ranking and confirm 4 areas for closer due diligence. - Our method used a three-step review: identify, score, then rank; the cut-off for escalation was a combined score of 12 or more out of 20. - We assumed stable production volumes, unchanged supplier mix, and no major acquisition during the period. - We found 3 changes in the period: 1 new issue added, 1 issue moved up in priority, and 1 issue removed after further review.

Illustrative (synthetic) example — Apparel manufacturing

Illustrative only. We assessed our impacts by starting with a longlist of topics, then testing each one against agreed severity and chance criteria before deciding what to focus on first. In practice, we gave more weight to issues with larger potential effect, longer recovery time, wider reach, and stronger likelihood signals; we also paid special attention to labour-intensive sites and water-stressed locations, which we treated as heightened-risk areas. For this review, we drew on 15 information sources, spoke with 10 internal and external stakeholders, involved 3 independent advisers, and used their input to adjust the scoring, confirm that due diligence was needed for 5 topics, and record 2 material changes from the prior cycle. - Our decision path was: gather evidence, test against the criteria, then prioritise the most significant matters. - The working assumptions were steady demand, no major regulatory shock, and no sudden loss of a key supplier. - The period brought 2 changes: one topic became more significant and one dropped below our threshold.

Quality ladder

  • Basic

    I used one screening process this year.

  • Better

    I used one group-wide screening process this year, based on our internal criteria, to sort impacts, risks and opportunities by significance.

  • Best

    I used one group-wide screening process this year across our operations and value chain, drawing on internal criteria, stakeholder and expert input, and due-diligence findings; we updated the list of priority topics because new site-level evidence showed higher exposure in two areas.

Check your understanding

Scenarios to work through

A group is drafting its materiality process note. The team has a workshop map and a spreadsheet of site, supplier and customer inputs, but the write-up only says the board reviewed the outcome.

QWhat extra process detail should be captured so a reader can see how the assessment was actually carried out?
Reveal model answer →

A preparer has ranked several issues using a scorecard. One issue was placed above the rest because it could cause serious harm even though the team thought it was less likely than others, and the draft does not explain why that issue came first.

QHow should the team explain its ranking approach so the ordering is understandable?
Reveal model answer →

The sustainability team consulted worker representatives and an external environmental adviser. Their draft mentions the meetings, but it does not say what parts of the assessment were shaped by that input.

QWhat should the preparer add about the use of outside and stakeholder input?
Reveal model answer →

Last year’s process focused mainly on operational sites. This year the team added a new supplier-screening step and changed the threshold for escalating climate-related issues after a severe weather review.

QWhat should the preparer disclose about changes in the process from one reporting cycle to the next?
