The European Sustainability Reporting Standards (ESRS) are mandatory reporting standards for sustainability disclosures under the EU Corporate Sustainability Reporting Directive (CSRD). Developed by the European Financial Reporting Advisory Group (EFRAG) and adopted by the European Commission in July 2023, ESRS represents the most comprehensive sustainability reporting framework globally, covering environmental, social, and governance topics through a double materiality lens.
ESRS consists of 12 standards organized into three categories: cross-cutting standards, environmental standards, and social/governance standards.
ESRS 1: General Requirements — Defines fundamental concepts, principles, and structure for sustainability reporting
ESRS 2: General Disclosures — Mandatory disclosures required for all companies
ESRS E1: Climate Change — Climate-related impacts, risks, and opportunities (based on TCFD/IFRS S2)
ESRS E2: Pollution — Air, water, and soil pollution
ESRS E3: Water and Marine Resources — Water consumption, withdrawal, and marine impacts
ESRS E4: Biodiversity and Ecosystems — Nature-related impacts and dependencies (aligned with TNFD)
ESRS E5: Resource Use and Circular Economy — Resource efficiency and circularity
ESRS S1: Own Workforce — Company's own employees and workers
ESRS S2: Workers in the Value Chain — Upstream and downstream workers
ESRS S3: Affected Communities — Communities impacted by operations
ESRS S4: Consumers and End-Users — Product/service users
ESRS G1: Business Conduct — Corporate governance and ethics
ESRS requires companies to assess double materiality — considering both impact materiality and financial materiality:
Impact Materiality (Inside-Out): How the company's activities affect people and the environment
Financial Materiality (Outside-In): How sustainability matters create financial risks and opportunities for the company
A topic is material if it meets either impact materiality or financial materiality criteria (or both). This differs from IFRS S1/S2, which uses only financial materiality.
CSRD applies to approximately 50,000 companies in the EU, making ESRS the most widely mandated sustainability reporting framework:
| Company Type | Employees | Revenue/Assets | Effective Date |
|---|---|---|---|
| Large EU companies (already under NFRD) | >500 | N/A | FY2024 (report 2025) |
| Other large EU companies | >250 OR | €50M revenue OR €25M assets | FY2025 (report 2026) |
| Listed SMEs | N/A | Listed on EU regulated markets | FY2026 (report 2027) |
| Non-EU companies | N/A | €150M EU revenue + EU subsidiary/branch | FY2028 (report 2029) |
CSRD mandates limited assurance of sustainability information from the first reporting year, progressing to reasonable assurance in the future. This makes ESRS disclosures subject to the same audit rigor as financial statements.
Step 1: Determine Applicability
Check if your company falls under CSRD scope based on size, listing status, and EU presence.
Step 2: Conduct Double Materiality Assessment
Identify material sustainability topics using ESRS 1 methodology:
Step 3: Identify Applicable ESRS Standards
ESRS 2 (General Disclosures) is mandatory for all. For topical standards (E1-E5, S1-S4, G1), disclose only material topics or explain why a topic is not material.
Step 4: Collect Data
Gather quantitative and qualitative data for material topics across value chain (upstream, own operations, downstream).
Step 5: Prepare Sustainability Statement
Create a dedicated sustainability statement within the management report, following ESRS structure and disclosure requirements.
Step 6: Obtain Assurance
Engage an auditor or assurance provider for limited assurance (mandatory from first reporting year).
Step 7: Publish
Include sustainability statement in management report, tag in ESEF (European Single Electronic Format) for machine-readability.
Materiality Approach:
Scope:
Mandatory vs. Voluntary:
Interoperability:
ESRS E1 (Climate) is aligned with IFRS S2 and TCFD. Companies can use ESRS disclosures to substantially meet IFRS S2 and GRI requirements with minimal additional work.
EFRAG is developing sector-specific ESRS for high-impact industries:
Phase 1 (expected 2026):
Phase 2 (expected 2027+):
Sector standards will provide more granular disclosure requirements tailored to industry-specific sustainability issues.
EFRAG has developed voluntary ESRS for SMEs (listed SMEs have mandatory simplified standards from FY2026):
Simplified Structure:
Streamlined disclosure requirements, reduced data points, proportionate to SME resources.
Voluntary Adoption:
Non-listed SMEs can voluntarily adopt to meet customer/investor demands or prepare for future regulation.
Value Chain Reporting:
Large companies subject to CSRD must report on value chain impacts, creating indirect pressure on SME suppliers to provide sustainability data.
