Definitions
204 proposed working definitions. Each carries a stable ID — cite DEF-A01 in a comment and it stays citable across releases.
DEF-I28
AI audit trail
A controlled record of a material AI use, including use case, user, tool or model, version, prompt, context, sources, output, edits, verification, decision, approval, exception and final use.
The term describes reporting auditability and does not imply an external audit or assurance conclusion.
DEF-I29
AI incident
An event in which an AI use creates or may create material reporting error, data exposure, prohibited use, harmful bias, control failure, unauthorised action or other adverse consequence.
Incidents should be contained, preserved, escalated, remediated and linked to affected reporting information and users.
DEF-I23
AI model risk
The risk that an AI system or model produces unsuitable or harmful reporting outcomes because of limitations in design, data, context, use, change, operation or human interaction.
Model risk should be assessed at use-case level and may include factual, bias, security, privacy, operational and governance risks.
DEF-I13
AI system
A machine-based system that generates outputs such as predictions, recommendations, classifications, content or actions from provided inputs and its model, rules or learned representations.
The precise legal or technical definition may differ by jurisdiction and should be addressed in future overlays.
DEF-I20
AI verification
The human-controlled evaluation of an AI-assisted output for factual accuracy, source support, completeness, logic, calculation, classification, consistency, bias, boundaries and intended use.
AI verification is specific to AI-assisted outputs. It should invoke data validation under E.7 where the output contains or transforms reporting data and general evidence evaluation under F.3 where the output supports a reporting conclusion. It is not formal model validation, legal verification or assurance.
DEF-G11
Anticipated financial effect
A reasonably supported future financial effect of a sustainability matter over the relevant time horizon that is not fully reflected in current-period financial information.
Anticipated effects should distinguish plans, scenarios, estimates and forecasts and should state material assumptions and uncertainty.
DEF-A08
Applicability
The condition of a reporting requirement or instrument applying to a specified organisation, entity, group, period, transaction, output or other defined reporting context.
Applicability may arise through law, regulation, listing, contract, voluntary adoption or another documented basis.
DEF-E26
Application control
A control embedded in or performed over a reporting application or workflow to support authorised, complete, accurate and controlled processing of information.
Application controls may depend on enterprise IT general controls that are outside the reporting practitioner's assessment scope.
DEF-F24
Assurance finding
A matter identified by an assurance practitioner during the engagement that may require clarification, evidence, correction, adjustment, remediation or communication to management or governance.
The assurance practitioner owns the finding; management owns its response and related reporting decisions.
DEF-F21
Assurance readiness
The condition in which the subject matter information, criteria, scope, responsibilities, methods, data, controls, evidence and records are sufficiently defined and mature to support consideration of an assurance engagement.
Readiness does not guarantee engagement acceptance, procedures, findings or an assurance conclusion.
DEF-F23
Assurance request
A request from an assurance practitioner for information, evidence, explanation, access or action relevant to an agreed or proposed assurance engagement.
Management responses should be controlled, authorised, complete and traceable and should not direct the assurance procedure.
DEF-G21
Authoritative reporting source
The approved data, methodology, narrative or record designated as the controlled source for a specified reported item or external channel.
This term refers to the internally approved and version-controlled source used for a reported item or channel. It is distinct from an external authoritative source under DEF-A05 and should be linked to the relevant owner, evidence and lineage.
DEF-A05
Authoritative source
A source whose issuing authority, legal status or recognised methodological role makes it an appropriate primary basis for a reporting conclusion in the specified context.
This term refers to an external or formally issued source whose authority is assessed in context. It is distinct from the internally designated authoritative reporting source in DEF-G21. Jurisdiction, adoption status, version, effective date and scope remain part of the authority assessment.
DEF-I22
Automation bias
The tendency to accept or prefer a system or AI output because it was generated automatically, even where contradictory evidence or judgement indicates it may be wrong.
Human review design should actively address automation bias rather than assume that a reviewer will detect errors.
DEF-I07
Automation exception
A record, condition or event in which an automated reporting workflow cannot process an item as expected or requires human investigation, override, correction or escalation.
Exceptions should remain visible, controlled and linked to the affected reporting population and decision.
DEF-B03
Business model
The system through which an organisation uses resources and relationships to undertake activities, create and deliver products or services and create, preserve or erode value and other outcomes.
The definition supports reporting analysis and does not replace the organisation's own strategic or financial description.
DEF-D14
Change request
A controlled proposal to modify an approved reporting baseline, requirement, method, data, disclosure, system, timetable or output, including rationale, impact assessment and required approval.
Implementation should not begin before the required authority and downstream control needs are identified.
DEF-G17
Claim substantiation
The controlled process of testing a sustainability claim against its criteria, evidence, boundary, period, methodology, comparator, qualifications and overall impression.
This term applies to broader explicit and implied sustainability claims, including performance, target, product, transition and leadership claims. Reporting-basis claims are separately defined in DEF-A14 and governed through A.8.
DEF-H04
Competence limit
A boundary beyond which a person lacks the demonstrated knowledge, skill, experience, authority or current capability to perform or approve a reporting task responsibly.
A competence limit should trigger supervision, consultation, specialist involvement, scope restriction, refusal or withdrawal.
DEF-I18
Context package
The authorised information, sources, examples, definitions, criteria and constraints supplied to an AI system for a defined reporting task.
The package should be relevant, complete enough for the task, version-controlled and protected according to information sensitivity and rights.
DEF-E05
Controlled data taxonomy
A governed hierarchy or classification system of terms, codes and relationships used to organise reporting data and metadata consistently across entities, systems and internal reporting processes.
A controlled data taxonomy supports internal data models and mappings. It is distinct from a reporting taxonomy used for external structured reporting under DEF-I09 and does not replace an authoritative external taxonomy.
DEF-G07
Corrective action
An action intended to address the cause or consequence of adverse performance or a target deviation and improve future performance.
Reporting of corrective action should identify status, owner, timing, resources and implementation evidence and should not imply effectiveness before evidence exists.
DEF-G20
Cross-channel consistency
The condition in which sustainability information remains accurate, compatible and appropriately explained across reports, filings, websites, presentations, questionnaires and data platforms.
Consistency permits documented differences where criteria, scope, period or purpose genuinely differ.
DEF-B12
Cross-topic relationship
A relationship in which one sustainability matter affects, depends on, mitigates, worsens or changes the interpretation of another matter.
Cross-topic relationships may involve trade-offs, co-benefits, rebound effects, cumulative effects or shared causes and should be evidenced rather than assumed.
DEF-A11
Crosswalk
A structured, source-based mapping that records the relationship between defined elements of two or more reporting instruments at an explicit level of granularity.
A defensible crosswalk records versions, rationale, mapping category, confidence, gaps and limitations.
DEF-G10
Current financial effect
A financial effect of a sustainability matter that is reflected in or relates to the current reporting period or current financial position, performance or cash flows.
The applicable reporting basis and finance or accounting owners determine the exact treatment and reporting location.
DEF-E02
Data element
A discrete item of information with a defined meaning, type, format and permissible values that may be sourced, calculated, aggregated or used in a metric or disclosure.
A data element may be a raw source value, attribute, dimension, calculated field or status and is narrower than a metric.
DEF-E11
Data owner
The person or function accountable for the definition, completeness, quality, evidence, review and approval of a specified reporting data set or element within assigned authority.
The data owner may differ from the person who prepares, uploads or technically administers the information.
DEF-E19
Data validation
The application of defined checks to determine whether reporting information meets specified completeness, accuracy, validity, consistency, timeliness, uniqueness, reasonableness and traceability criteria.
Data validation tests reporting data and information and may operate as a control under F.2. It is distinct from AI-output verification under DEF-I20 and does not by itself constitute internal audit or independent assurance.
DEF-G16
Decision-useful disclosure
Reporting information that is relevant, understandable, connected and sufficiently specific to support the decisions or oversight activities of the intended users.
Decision usefulness is assessed in the context of the reporting purpose and does not replace the applicable disclosure requirements.
DEF-B06
Dependency
An organisation's reliance on environmental, human, social, financial, manufactured, intellectual or other resources and relationships that support its activities, resilience or outcomes.
A dependency may create exposure but is not automatically an impact or a material organisational risk.
DEF-I10
Digital tag
A machine-readable association between a reported fact or disclosure and a taxonomy concept, context, unit, dimension and other required metadata.
The tag should accurately represent the underlying disclosure and should not be selected solely by label similarity.
DEF-I12
Digital-tagging validation
The application of technical and semantic checks to structured reporting information, including concepts, contexts, units, dimensions, duplicates, calculations and filing-package rules.
Successful technical validation does not by itself demonstrate disclosure compliance or reporting accuracy.
DEF-E14
Disaggregation
The separation and presentation of reporting information by relevant dimensions such as entity, site, geography, workforce group, product, topic or value-chain stage.
Disaggregation is used where aggregate information would obscure material variation or where required by the reporting basis.
DEF-D03
Disclosure architecture
The structured organisation of reporting content across sections, documents, web pages, data books or submissions, including the relationship among requirements, material matters, narrative, metrics, evidence and navigation.
Disclosure architecture precedes detailed drafting and does not by itself demonstrate disclosure completeness.
DEF-G12
Disclosure outline
A controlled disclosure-level plan stating the reporting question, required facts, narrative sequence, metrics, targets, evidence, limitations, owner, reviewer and completion criteria.
A disclosure outline implements the approved architecture and does not authorise changes to reporting scope or materiality.
DEF-C11
Double materiality
An approach that considers impact materiality and financial materiality as distinct but related perspectives and includes a matter when it is material under either required perspective.
Double materiality does not permit one perspective to cancel the other or require both perspectives to be met.
DEF-G14
Entity-specific disclosure
A disclosure grounded in the organisation's actual business model, scope, governance, activities, evidence, performance, impacts, risks, opportunities and circumstances.
Entity-specific disclosure is distinct from generic standard wording, peer language or policy boilerplate.
DEF-I11
Entity-specific extension
A taxonomy concept created by an entity where an applicable standard concept does not adequately represent the reported information.
Extensions should be necessary, clearly defined, anchored and controlled to preserve comparability and avoid duplication.
DEF-F16
Evidence pack
An indexed and controlled collection of working papers and supporting evidence assembled for management review, assurance readiness or another defined reporting purpose.
An evidence pack should be relevant, cross-referenced, protected and distinguish authoritative and superseded versions.
DEF-H06
Evidence-based challenge
A proportionate and documented questioning process directed to a reporting assertion, assumption, explanation or decision and supported by relevant criteria and evidence.
Challenge should seek clarification, corroboration or resolution and preserve respectful professional conduct.
DEF-D16
Finalisation
The controlled process of reconciling approved content, data, evidence, cross-references, design, translations, sign-offs and unresolved matters into the authorised release package.
Finalisation ends with controlled handover and archive and is distinct from post-publication correction.
DEF-G09
Financial connectivity
The supported relationship among a sustainability matter and the organisation's financial planning, capital allocation, financial position, performance, cash flows, access to finance, cost of capital or financial reporting.
Financial connectivity does not itself establish accounting recognition, valuation or financial-statement materiality.
DEF-C10
Financial materiality
A conclusion that a sustainability-related risk, opportunity or information meets the applicable threshold for its potential effect on the organisation's financial position, performance, cash flows, access to finance, cost of capital, resilience or prospects.
The precise objective and threshold are determined by the applicable reporting basis and should not be confused with impact materiality.
DEF-G18
Greenwashing risk
The risk that sustainability communication creates a false, exaggerated, incomplete or otherwise misleading impression through wording, omission, imagery, evidence, comparison, scope or presentation.
Greenwashing risk may arise even where an individual statement is narrowly true but the overall impression is misleading.
DEF-B05
Impact
An actual or potential positive or negative effect that an organisation has or may have on people, the environment or the economy through its activities, products, services or business relationships.
The definition supports identification and classification; materiality, severity and legal responsibility are determined through other processes.
DEF-C09
Impact materiality
A conclusion that an actual or potential impact on people, the environment or, where relevant under the reporting basis, the economy meets the applicable significance criteria for reporting.
The criteria may include severity and likelihood and should be applied to specific impacts rather than topic labels alone.
DEF-H20
Inappropriate pressure
Pressure from hierarchy, commercial interests, deadlines, incentives, clients or other sources that seeks to compromise reporting criteria, evidence, judgement, controls, disclosure or professional conduct.
Inappropriate pressure should be resisted and escalated proportionately.
DEF-F26
Independence threat
A circumstance or relationship that may compromise or appear to compromise the objectivity and independence required for an assurance, audit, certification or similar activity.
Threats may include self-review, management participation, advocacy, familiarity, self-interest and intimidation and are assessed under the applicable professional requirements.
DEF-F28
Independent assurance
An engagement in which an independent assurance practitioner obtains evidence and expresses a conclusion intended to enhance users' confidence in subject matter information against suitable criteria.
The scope, level, criteria, period and conclusion should be stated accurately and should not be extended beyond the assurance report.
DEF-A10
Interoperability
The ability to use, connect or reconcile information, data, processes or disclosures across reporting instruments while preserving the requirements and limitations of each instrument.
Interoperability does not imply legal equivalence, automatic compliance or official endorsement.
DEF-C13
Likelihood
The possibility that a potential impact, risk, opportunity or other future condition will occur within the relevant time horizon.
Likelihood is not applied to discount an impact that has already occurred and should be assessed using the applicable materiality perspective and method.
DEF-G23
Limitation disclosure
A specific explanation of a data, method, boundary, evidence, control, comparability or other constraint affecting the completeness or interpretation of reported information.
A limitation disclosure should identify affected information, reason, effect and improvement or reassessment where applicable.
DEF-F18
Management representation
A documented statement by authorised management concerning responsibility, completeness, known matters, controls, estimates, limitations or other reporting information within its knowledge and authority.
A management representation may supplement but does not replace other evidence needed to support the reporting conclusion.
DEF-F17
Management review
An accountable review performed by authorised management or an appointed reviewer to challenge reporting information, evidence, judgements and unresolved matters before approval.
Management review is not independent assurance and should be evidenced through substantive questions, responses and conclusions.
DEF-A12
Market and counterparty requirement
A sustainability information obligation, condition, methodology or request arising from an exchange, investor, lender, rating or data provider, customer, procurement function or other external counterparty.
Its status may be legal, listing-based, contractual, proprietary, voluntary or informal and must be identified rather than assumed.
DEF-H14
Market-sensitive information
Non-public reporting-related information that may affect market participants or securities decisions and therefore requires authorised handling and release.
The classification and treatment of market-sensitive information are determined under applicable law and market rules.
DEF-C16
Material matter
A sustainability matter, impact, risk, opportunity, topic or related information concluded to be material under the applicable reporting basis and perspective.
The object of the conclusion and its terminology may differ by reporting instrument and should be explained in the relevant Standards View.
DEF-C08
Materiality assessment
A controlled process for identifying, evaluating and concluding which sustainability matters or information meet the materiality criteria required by the applicable reporting basis.
The process may include impact, financial or both perspectives and requires evidence, judgement, approval and maintenance.
DEF-C14
Materiality threshold
A documented cut-off, tier or decision rule used to support the distinction between matters that proceed to a material conclusion and matters that do not, subject to qualitative judgement and governance approval.
A threshold is not a universal number and should be calibrated, sensitivity-tested and prevented from excluding non-compensable or severe cases mechanically.
DEF-E01
Metric
A defined quantitative or qualitative measure used to describe sustainability-related performance, condition, activity, outcome, impact, risk, opportunity or other reporting information.
A metric should be governed through a protocol that states its purpose, unit, period, boundary, method, owner and evidence.
DEF-E07
Metric boundary
The criterion defining which entities, activities, locations, value-chain stages, populations, periods or other elements are included in or excluded from a metric.
A metric boundary applies to one metric or defined data set and may differ from the overall reporting perimeter. It should be documented in the metric methodology and reconciled to the umbrella reporting-boundary concept in DEF-C07.
DEF-D07
Milestone
A defined reporting event or deliverable point with an owner, acceptance criteria and planned date used to monitor progress and dependencies.
Completion should be based on evidence that the acceptance criteria are met, not only on the passage of time.
DEF-G13
Narrative logic
The structured sequence and relationship through which a disclosure explains context, governance, approach, action, performance, targets, outcomes and limitations.
The appropriate logic depends on the reporting question and should not force every disclosure into one standard template.
DEF-I06
Non-delegable judgement
A reporting decision that must remain with an authorised and competent human because of its legal, ethical, governance, materiality, assurance, sign-off or public-consequence nature.
Technology may support but should not become the decision owner for a non-delegable judgement.
DEF-H17
Objectivity threat
An interest, relationship, role, service, incentive or pressure that may compromise or appear to compromise a person's objectivity in sustainability reporting, advisory, review or assessment work.
Formal independence threats in assurance, audit, certification or similar activities are defined in DEF-F26 and determined under the applicable professional framework.
DEF-G08
Organisational connectivity
The supported relationship among a sustainability matter and the organisation's governance, business model, strategy, risk management, actions, resources, metrics and targets.
Connectivity should be demonstrated through actual processes, decisions and evidence rather than generic statements of integration.
DEF-H16
Perceived conflict
A circumstance that a reasonable informed observer may view as impairing objectivity even where the practitioner believes no actual impairment exists.
Public perception should be considered when selecting safeguards and communication.
DEF-G01
Performance analysis
The structured examination of current and historical sustainability information to identify levels, movements, patterns, concentrations, anomalies and supported explanations.
Performance analysis should use validated and comparable information and should not be presented as a forecast or causal conclusion beyond the evidence.
DEF-G30
Post-publication monitoring
The controlled review of published sustainability information, links, downloads, external reuse, identified errors, changed evidence and correction status after release.
Monitoring should have defined ownership, cadence, issue intake, escalation and closure.
DEF-F27
Preparation service
A service that assists management in compiling, calculating, drafting, organising or otherwise preparing sustainability reporting information without providing an independent assurance conclusion.
Management retains responsibility for decisions, judgements, information and publication.
DEF-H26
Professional currency
The condition of maintaining relevant and current knowledge, applied capability and awareness of changes affecting a person's sustainability reporting role.
Professional currency requires learning, application, reflection and reassessment and is not demonstrated by attendance hours alone.
DEF-H01
Professional integrity
The consistent application of honesty, truthfulness and responsible conduct in sustainability reporting work, including correction of known misleading information.
Integrity includes avoiding association with materially false, incomplete or misleading reporting information.
DEF-I25
Prompt injection
An instruction embedded in user or retrieved content that seeks to alter, bypass or redirect an AI system's intended task, controls or information handling.
Reporting workflows using retrieved or external content should include proportionate controls to detect and contain malicious or irrelevant instructions.
DEF-F25
Proposed assurance adjustment
A change to subject matter information or related reporting proposed or identified during an assurance engagement for management's consideration and decision.
The effect on data, disclosures, controls, comparatives and other channels should be assessed and authorised by management.
DEF-E16
Proxy
An observable measure used as a substitute for a required but unavailable measure because it is expected to represent or correlate with the underlying matter sufficiently for the reporting purpose.
The representativeness, bias and limitations of the proxy should be assessed and disclosed.
DEF-G29
Published-information correction
A controlled change, clarification, restatement, withdrawal or replacement of sustainability information after public release.
The original and corrected information, reason, affected period, approvals, notifications and downstream updates should remain traceable.
DEF-C15
Qualitative override
A documented decision to depart from the outcome of a mechanical score, ranking or threshold because relevant qualitative evidence, severity, uncertainty, legal or methodological considerations justify a different conclusion.
Overrides should be governed, evidenced, consistently applied and retained whether they add or remove a matter.
DEF-H09
Reasonable alternative
A credible course, method or conclusion that could be selected within the applicable reporting criteria and available evidence.
Reasonable alternatives should be considered where they could materially affect the conclusion or reporting output.
DEF-E24
Record integrity
The condition in which reporting records remain complete, accurate, protected from unauthorised alteration or deletion, version-identifiable and retrievable for their required retention period.
Record integrity includes working, reviewed, approved, published, superseded and archived records.
DEF-H19
Recusal
The documented withdrawal of a person from specified reporting decisions, preparation, review or approval because of a conflict, competence issue or other professional threat.
Recusal should identify the affected responsibilities, replacement arrangements and continuing information restrictions.
DEF-G27
Reporting accessibility
The quality of reporting information being perceivable, understandable, navigable and usable by people with diverse access needs and technologies.
Formal accessibility compliance may require specialist assessment beyond the Global Core.
DEF-F01
Reporting assertion
A statement or implicit condition about the completeness, accuracy, validity, classification, boundary, presentation, traceability or other quality of reported sustainability information.
Assertions provide a basis for identifying reporting risks, control objectives and evidence needs.
DEF-A07
Reporting basis
The documented combination of mandatory, voluntary, listing, contractual, policy-based and other criteria selected or required for a specified organisation, reporting period and reporting output.
The reporting basis should identify applicable instruments, status, scope, assumptions, reliefs and limitations.
DEF-C07
Reporting boundary
A criterion or rule that determines what is included in or excluded from a reporting perimeter.
A reporting boundary is an umbrella rule used to determine the reporting perimeter. A metric-specific boundary is defined separately in DEF-E07 and should be reconciled to the overall perimeter. Boundaries may be organisational, operational, value-chain, geographic, topic-specific or temporal.
DEF-F04
Reporting control
A preventive, detective or corrective action, procedure, configuration or review designed to address a sustainability reporting risk and support a control objective.
A reporting control may be manual, automated or hybrid and should have an owner, frequency, precision, evidence and exception route.
DEF-F10
Reporting control design effectiveness
The condition in which a reporting control, if operated as designed by competent persons, is capable of addressing the defined risk and achieving the control objective.
This is a management reporting-control concept describing whether the control is capable of addressing the defined risk. It is distinct from evidence that the control operated and does not constitute an audit or assurance conclusion.
DEF-F11
Reporting control operating effectiveness
The condition in which a suitably designed and implemented reporting control operated with the required frequency, precision and evidence during the relevant period.
This is a management reporting-control concept describing operation during the relevant period. Formal audit or assurance conclusions about operating effectiveness remain with the authorised audit or assurance practitioner.
DEF-D02
Reporting delivery model
The arrangement of internal and external workstreams, responsibilities, systems, processes and review interfaces through which reporting outputs are produced.
A delivery model may be centralised, decentralised or hybrid and remains subject to the role and accountability architecture.
DEF-F14
Reporting evidence appropriateness
The quality of reporting evidence, considered through its relevance, reliability, authenticity, provenance, currency and consistency with the reporting conclusion.
The term is used for reporting preparation, management review and assurance readiness. The independent assurance practitioner determines evidence appropriateness for an assurance engagement under the applicable standard.
DEF-F13
Reporting evidence sufficiency
The condition in which the quantity and coverage of reporting evidence are adequate for the reporting conclusion and risk in context.
The term is used for reporting preparation, management review and assurance readiness. The independent assurance practitioner determines evidence sufficiency for an assurance engagement under the applicable standard.
DEF-C01
Reporting governance
The structures, responsibilities, decision rights, information flows, controls and review arrangements through which sustainability reporting is directed, managed, challenged and approved.
Reporting governance concerns the reporting process and is distinct from governance and business conduct reported as sustainability subject matter.
DEF-A04
Reporting instrument
A standard, framework, law, regulation, listing rule, official methodology or other structured set of criteria used to determine or organise sustainability reporting requirements.
Market and counterparty requests are treated separately in A.7 unless they themselves constitute a formal reporting instrument.
DEF-C06
Reporting perimeter
The defined set of entities, operations, activities, business relationships, value-chain stages, geographies, topics, metrics and periods included in a reporting output or assessment.
A reporting perimeter may differ by instrument, topic, metric or disclosure and should be reconciled to other organisational perimeters.
DEF-F02
Reporting risk
The possibility that a sustainability reporting assertion, requirement, judgement, process or public claim will not be achieved or supported to the required quality.
Reporting risk may arise from data, methods, systems, people, judgement, change, governance, evidence or publication.
DEF-D01
Reporting strategy
The approved operational approach for fulfilling sustainability reporting objectives through defined outputs, channels, design principles, quality objectives, governance interfaces and major delivery assumptions.
It translates the reporting basis and materiality conclusions into an execution direction and does not replace corporate sustainability strategy.
DEF-I09
Reporting taxonomy
A controlled system of reporting concepts, definitions, data types, relationships and other metadata used to structure or tag reported information.
A reporting taxonomy is used to structure or tag reported information, including external digital filings. It is distinct from the internal controlled data taxonomy in DEF-E05 and does not replace the applicable reporting requirements or filing rules.
DEF-I01
Reporting technology
A digital tool, platform, application, service or technical component used to support sustainability reporting data, workflow, evidence, analysis, disclosure, filing or monitoring.
Reporting technology should be selected and governed against defined reporting, control, data and lifecycle requirements.
DEF-A14
Reporting-basis claim
A public or formal statement about an organisation's compliance, accordance, alignment, adoption, reference, coverage, use or endorsement in relation to a reporting instrument, reporting basis or reporting process.
This term is narrower than a general sustainability claim. A reporting-basis claim is governed through A.8; broader environmental, social, performance, target and leadership claims are substantiated under G.7, and assurance or certification wording is controlled under F.9.
DEF-I02
Reporting-technology use case
A defined reporting purpose for which a technology is proposed or used, including users, process, data, outputs, decisions, controls and expected benefit.
Use-case definition should precede tool selection and should identify non-delegable judgement and specialist boundaries.
DEF-A13
Requirements-to-disclosure register
A controlled record linking each applicable reporting requirement to its source, version, owner, treatment, evidence, disclosure location, review status, omissions and change history.
The register may also support data, control, assurance-readiness and curriculum views but remains distinct from the published content index.
DEF-I31
Responsible AI governance
The structures, principles, ownership, approval, controls, monitoring, incident response and lifecycle arrangements used to manage AI use and preserve trustworthy human-led reporting.
Governance should be demonstrated through actual use, records and decisions and should not be presented as proof that every AI output is reliable or compliant.
DEF-E21
Restatement
The revision of previously reported comparative information to correct an error or reflect another change where retrospective revision is required or chosen under the reporting basis.
A restatement should identify the reason, periods and information affected and preserve the originally published record.
DEF-H22
Retaliation risk
The possibility that a person may suffer disadvantage, intimidation, exclusion or other adverse treatment for raising a concern or refusing inappropriate conduct in good faith.
Retaliation risk should inform confidentiality, route selection, protection, monitoring and specialist consultation.
DEF-G24
Sensitive information
Reporting-related information requiring restricted handling because of privacy, confidentiality, privilege, security, commercial sensitivity, market sensitivity, legal prohibition or other authorised protection.
Classification and disclosure treatment should be determined through the appropriate legal and information-governance process.
DEF-C12
Severity
The seriousness of a negative impact, commonly considered through dimensions such as scale, scope and irremediable character under the applicable methodology.
Severity should not be reduced through unsupported averaging where one dimension indicates a severe or potentially irremediable effect.
DEF-C05
Sign-off
A documented representation or approval by an authorised person or body that specified review conditions and responsibilities have been satisfied or that stated unresolved matters remain.
C.2 defines who may sign and the decision-right architecture; F.5 governs the substantive review, representation and operational sign-off process. Sign-off is not independent assurance and does not by itself prove that effective review occurred.
DEF-H07
Significant professional judgement
A reporting decision requiring interpretation, alternatives, uncertainty or material professional reasoning that may significantly affect reporting information, claims or users.
The judgement should identify criteria, evidence, authority, alternatives, uncertainty, approval and reassessment.
DEF-A06
Source hierarchy
A documented ordering of source types according to their authority and relevance for the reporting question being analysed.
The hierarchy should distinguish normative sources from implementation material, educational material and secondary commentary.
DEF-B11
Specialist evidence
Information, analysis or conclusions produced by a subject-matter specialist under a defined scope, method, evidence base, assumptions, limitations and review arrangement.
The reporting practitioner may evaluate reporting relevance and completeness but should not claim to reperform specialist work outside their competence.
DEF-E25
Spreadsheet control
A preventive, detective or corrective measure addressing risks in a spreadsheet or other end-user computing tool, including input, formula, link, version, access, override and review risks.
Spreadsheet controls should be proportionate to the materiality and complexity of the reporting use.
DEF-F22
Subject matter information
The sustainability information that results from measuring or evaluating the underlying subject matter against identified criteria and is proposed or used as the object of an assurance engagement.
The exact meaning and terminology are determined by the applicable assurance framework.
DEF-B09
Subject-matter literacy
Sufficient conceptual and methodological understanding of a sustainability topic to perform reporting tasks, question evidence, recognise limitations, communicate accurately and know when specialist expertise is required.
Subject-matter literacy is not the same as professional qualification or authority to perform specialist scientific, legal, engineering, clinical, valuation or investigation work.
DEF-B10
Subject-matter specialist
A person or team with demonstrably deeper expertise relevant to a defined sustainability topic, methodology, data source or technical judgement.
Specialist status is contextual and should be supported by competence, scope, independence or conflict considerations and appropriate evidence.
DEF-B01
Sustainability context
The organisational and external environmental, social, economic, geographic and institutional conditions needed to understand and interpret a sustainability matter.
Context analysis frames reporting questions and information needs but does not itself determine materiality or specialist conclusions.
DEF-B08
Sustainability-related opportunity
A potential beneficial effect on an organisation's objectives, prospects, operations, resilience or value arising from a sustainability matter or the organisation's response to it.
An opportunity should not be assumed merely because an action has a positive sustainability intent; evidence and materiality remain separate questions.
DEF-B07
Sustainability-related risk
Uncertainty arising from a sustainability matter that may negatively affect an organisation's objectives, prospects, operations, resilience, access to resources or ability to create, preserve or erode value.
Financial materiality, magnitude and valuation are assessed under the applicable reporting basis and Domain C.
DEF-B02
Systems thinking
An approach that analyses elements, relationships, feedback loops, thresholds, time delays, cumulative effects and emergent outcomes rather than treating matters in isolation.
The depth of analysis should be proportionate to the reporting question and should not imply specialist scientific modelling.
DEF-G06
Target deviation
A material difference between actual target performance and the applicable milestone, trajectory or expected progress measure.
A deviation assessment should distinguish performance from target, boundary, denominator and methodology changes.
DEF-H23
Technical translation
The accurate explanation of technical reporting requirements, evidence, methods, judgement and limitations in language and formats appropriate to a defined audience.
Technical translation should simplify complexity without altering meaning or removing material qualification.
DEF-D17
Third-party contributor
An external person or organisation providing advisory, specialist, data, software, translation, design, assurance-related or other services used in reporting work.
Third-party involvement does not transfer management accountability or remove the need for competence, conflict and deliverable review.
DEF-I03
Tool inventory
A controlled register of reporting tools and services, including owner, purpose, users, data, vendor, version, risk, approval, status, integrations and lifecycle information.
The inventory should include unapproved or discovered shadow use where relevant and distinguish active, restricted, suspended and retired tools.
DEF-E18
