ESRS are EU sustainability reporting standards covering double materiality, disclosures, value chains, metrics, targets, and governance.
The European Sustainability Reporting Standards (ESRS) set out how companies within the scope of the European Union’s Corporate Sustainability Reporting Directive (CSRD) prepare sustainability information. ESRS cover environmental, social, and governance matters and use double materiality: a company considers both its impacts on people and the environment and the sustainability-related risks and opportunities that could affect its financial position or performance.
The CSRD and related EU law determine which companies must report and when. ESRS determine much of what those companies disclose and how the disclosures are structured. That distinction matters because not every company with EU operations is automatically subject to ESRS, and the applicable scope and phase-in rules can change.
| Source | Main function | Practical question |
|---|---|---|
| CSRD and related EU legislation | Establish the reporting obligation, scope, timing, and legal framework | Must this undertaking prepare sustainability reporting, and for which period? |
| ESRS | Specify reporting concepts, disclosures, presentation, and measurement requirements | What sustainability information must the undertaking report, and how? |
| EFRAG implementation guidance | Provide non-authoritative support for applying the adopted standards | How might a company perform materiality and value-chain work in practice? |
| Company sustainability statement | Apply the requirements to the reporting entity’s facts | Which impacts, risks, opportunities, policies, actions, metrics, and targets are reported? |
Legal scope is fact-specific. Group structure, listing status, size tests, jurisdiction, reporting period, and transitional provisions can all matter. Readers should use the current consolidated legislation and qualified professional advice rather than infer legal coverage from a company name, location, or prior-year report.
The first adopted sector-agnostic set contains two cross-cutting standards and ten topical standards.
| Group | Standards | Subject |
|---|---|---|
| Cross-cutting | ESRS 1 and ESRS 2 | General requirements and general disclosures |
| Environmental | E1 through E5 | Climate change; pollution; water and marine resources; biodiversity and ecosystems; resource use and circular economy |
| Social | S1 through S4 | Own workforce; workers in the value chain; affected communities; consumers and end-users |
| Governance | G1 | Business conduct |
ESRS 1 explains concepts and preparation requirements. ESRS 2 contains general disclosures, including information about governance, strategy, and the process used to identify and manage impacts, risks, and opportunities. The topical standards provide disclosures for matters found to be material, subject to the requirements and exceptions in the applicable legal text.
This architecture is not a checklist proving that every topical disclosure is material for every company. The company must perform and document its materiality assessment, apply the detailed requirements, and explain required conclusions where the standards call for that explanation.
Double materiality has two related but distinct dimensions:

A["Map company activities and business relationships"] --> B["Assess actual and potential impacts on people and the environment"]
B --> C["Assess sustainability-related financial risks and opportunities"]
C --> D["Identify matters material under either dimension or both"]
D --> E["Apply relevant ESRS disclosures and entity-specific information"]
The two dimensions can overlap without producing identical conclusions. For example, serious water impacts in a supplier region may be impact-material before they produce a measurable effect on the reporting company’s cash flow. Conversely, a carbon-pricing exposure may be financially material even when the company’s direct emissions are modest.
A practical review usually follows a traceable sequence, although ESRS do not prescribe one universal process for every company:
Materiality is not a survey popularity contest. Stakeholder engagement can inform the evidence, particularly about impacts, but management still needs a reasoned assessment under the standards.
ESRS can require consideration beyond the consolidated reporting group’s own operations. Material impacts, risks, or opportunities may be connected to suppliers, distributors, customers, product use, or end-of-life activity through business relationships.
That does not mean every disclosure requires complete data from every supplier and customer. The relevant boundary depends on the material matter and the applicable disclosure requirement. Analysts should distinguish:
EFRAG’s value-chain guidance can help explain implementation, but the adopted standards and EU law remain authoritative.
Assume a hypothetical beverage manufacturer operates one plant in a water-stressed region and buys agricultural inputs from several suppliers in the same watershed.
For impact materiality, the company might assess how its withdrawals and supplier practices affect local water availability, ecosystems, workers, and communities. The assessment would consider severity and, for potential impacts, likelihood. For financial materiality, it might evaluate production interruptions, permit constraints, higher input costs, capital expenditure, insurance, financing access, and changes in customer demand.
If water is material under either dimension, a useful sustainability statement would connect:
A statement that the company “supports water stewardship” is not equivalent to this evidence. Nor does reporting a lower withdrawal number establish the reason: production volume, facility sales, weather, estimation changes, or efficiency measures could each affect the result.
| Framework or standard | Primary orientation | Materiality lens | Key distinction |
|---|---|---|---|
| ESRS | Sustainability reporting under the EU CSRD framework | Impact materiality and financial materiality | EU legal reporting standards with detailed topical requirements |
| IFRS S1 and IFRS S2 | Sustainability-related financial disclosures for capital-market users | Information material to primary users of general purpose financial reports | Global baseline designed by the ISSB; jurisdictional adoption determines legal use |
| TCFD recommendations | Climate-related financial disclosure | Climate-related financial risks and opportunities | Historical recommendation framework now incorporated into IFRS S1 and IFRS S2 |
| Integrated Reporting Framework | Connected explanation of value creation, preservation, and erosion | Matters affecting value creation over time | Principles-based reporting structure rather than a granular sustainability disclosure standard |
| GRI Standards | Reporting an organization’s impacts on the economy, environment, and people | Impact-oriented | Broader stakeholder and impact-reporting orientation |
Interoperability can reduce duplication, but it does not make these sources interchangeable. A company should map definitions, reporting boundaries, materiality decisions, metrics, and legal requirements rather than assume one report automatically satisfies another regime.
Start with the materiality process and follow each material matter through the report.
| Evidence to inspect | Questions to ask |
|---|---|
| Reporting basis | Which entity, subsidiaries, reporting period, standards, exemptions, and transitional provisions are covered? |
| Materiality assessment | Which impacts, risks, and opportunities were identified, what thresholds were used, and who approved the conclusion? |
| Value-chain boundary | Which upstream and downstream relationships are included, and where are estimates used? |
| Policies and actions | Who is accountable, what resources are committed, and what part of the material matter is addressed? |
| Metrics | Is the definition stable, is the boundary clear, and can the figure be reconciled across periods? |
| Targets | What are the baseline, deadline, units, scope, dependencies, and progress? |
| Financial connections | Do stated risks and opportunities connect to capital spending, operating costs, revenue, assets, financing, or assumptions? |
| Assurance and controls | What information was assured, at what level, under which standard, and what remains outside the assurance scope? |
The goal is not to convert all ESRS information into one score. It is to identify evidence that changes cash-flow expectations, risk assessment, stewardship priorities, or confidence in management’s reporting.
The European Commission’s CSRD implementing and delegated acts page links the adopted ESRS legal texts and subsequent amendments. The original sector-agnostic standards were published as Commission Delegated Regulation (EU) 2023/2772.
EFRAG provides non-authoritative ESRS implementation guidance on materiality assessment, value-chain information, and detailed data points. Because amendments and phase-in rules can change, consult the current consolidated EU text for an actual reporting obligation.
