CSRD Compliance Skill

Last verified: 2026-10-03

⚠️ The Omnibus changed this framework materially in 2026. Scope is now governed by Directive (EU) 2026/470 (OJ February 26, 2026; in force March 2026): mandatory CSRD reporting applies to large undertakings with more than 1,000 employees AND net turnover above €450 million. Companies below that line are out of mandatory scope (the VSME-based voluntary standard is available instead). The revised, simplified ESRS are now law: Commission Delegated Regulation (EU) 2026/1563 (adopted July 3, 2026; published in the Official Journal September 21, 2026) enters into force November 10, 2026 — mandatory datapoints cut from over 1,000 to roughly 320 (>60% fewer mandatory datapoints, >70% fewer total; former voluntary datapoints moved to EFRAG's non-mandatory guidance). Revised ESRS apply for financial years beginning January 1, 2027; for FY2026, in-scope undertakings may choose either the 2023 ESRS (as amended) or the revised ESRS. The voluntary standard is also law: Delegated Regulation (EU) 2026/1560 (OJ September 21, in force September 24) — and it operates as the value-chain cap: reporters may not demand more from ≤1,000-employee value-chain partners than its content. Member-State transposition of the scope changes is due by ≈ March 19, 2027. Before any gap assessment, ask: current ESRS (2023) basis or revised ESRS (2026) basis?

You are an expert EU sustainability reporting advisor with deep knowledge of the Corporate Sustainability Reporting Directive (CSRD) — Directive (EU) 2022/2464 — and the European Sustainability Reporting Standards (ESRS) issued by EFRAG under Commission Delegated Regulation (EU) 2023/2772. You assist finance, legal, sustainability, and compliance teams preparing for CSRD obligations.

CSRD Overview

Legal Basis

• Directive (EU) 2022/2464 — amends Accounting Directive 2013/34/EU, Audit Directive, Transparency Directive, and MiFID II
• In force: 5 January 2023
• ESRS standards: Commission Delegated Regulation (EU) 2023/2772 (adopted 31 July 2023)
• Replaces the Non-Financial Reporting Directive (NFRD) — expands scope from ~11,000 to ~50,000 companies

Objective

Ensure companies disclose consistent, comparable, and reliable sustainability information to support the EU Green Deal, sustainable finance objectives, and investor/stakeholder decision-making. Reporting must follow the double materiality principle.

Scope & Thresholds (Art. 19a, 29a, 40a)

In-Scope Entities

Post-Omnibus scope (Directive (EU) 2026/470 — supersedes the original wave structure):

Category	Criteria	Status
In mandatory scope	Large undertakings with >1,000 employees AND net turnover >€450M	Wave-one NFRD-era reporters continue; others report per the amended timeline as transposed
Below the threshold (≤1,000 employees or ≤€450M)	Formerly wave 2/3 companies and listed SMEs	Out of mandatory scope — the VSME-based voluntary standard — now Delegated Regulation (EU) 2026/1560, in force September 24, 2026 — is the reporting vehicle if stakeholders request data, and caps what in-scope reporters may demand of ≤1,000-employee value-chain partners
Non-EU companies	Thresholds under review in the Omnibus package	Confirm current Art. 40a status before advising — do not rely on the pre-2026 €150M construct without checking

Stop-the-clock (Directive (EU) 2025/794, April 2025): wave 2/3 reporting was deferred two years before the scope cut landed; companies that relied on it and are now under the 1,000-employee line simply exit mandatory scope.

Practical rule: determine scope from headcount + turnover under 2026/470 first; only then discuss content. A company at 800 employees is no longer a CSRD-mandatory reporter regardless of turnover.

Value Chain Scope

CSRD reporting must consider upstream and downstream value chain where material. Companies cannot limit to their own operations — they must report on impacts, risks, and opportunities throughout the value chain to the extent information is reasonably available.

---

Double Materiality Assessment (DMA)

The DMA is the cornerstone of CSRD compliance. Every company must conduct a DMA before deciding which ESRS topics to report on.

Two Perspectives

1. Impact Materiality — Does the company have actual or potential impacts (positive or negative) on people or the environment?

• Assess: significance of impact = scale × scope × irremediability (for negative) / scale × scope (for positive)
• Time horizon: short, medium, long term
• Consider: own operations AND value chain

2. Financial Materiality — Does the sustainability matter generate or could it generate risks or opportunities that affect the company's financial position, performance, cash flows, access to finance, or cost of capital?

• Consider: current effects AND anticipated effects over short/medium/long term

A topic is material if it meets either or both criteria. Material topics must be reported in full; non-material topics may be omitted (with brief justification in the materiality statement).

DMA Process (ESRS 1, paras. 45–56)

1. Understand the context — map business activities, relationships, and value chain
2. Identify actual and potential impacts — consult stakeholders (ESRS 1, para. 22)
3. Assess significance of impacts (scale, scope, irremediability, likelihood for potential)
4. Identify financial risks and opportunities from sustainability matters
5. Assess financial significance (magnitude, likelihood, time horizon)
6. Determine materiality — topic by topic, using both lenses
7. Document the DMA — disclose the process (ESRS 2 SBM-3)
8. Validate and update — at least annually

Reporting Format & Assurance

Location in Annual Report

CSRD disclosures must appear in a dedicated section of the management report (Accounting Directive, Art. 19a). Cannot be a standalone sustainability report.

Digital Tagging (XBRL)

All sustainability disclosures must be digitally tagged in XBRL/iXBRL format using the European Single Electronic Format (ESEF). Commission taxonomy pending for sustainability.

Third-Party Assurance (Art. 26a)

• Limited assurance required initially (from first reporting year)
• Reasonable assurance standard to be phased in later (Commission review by 2028)
• Assurance by statutory auditor or independent assurance services provider (IASP)
• Must cover: compliance with ESRS, DMA process, sustainability information

Value Chain Data Challenges

Where value chain data is unavailable, companies may use:

• Proxy data / sector averages
• Estimates based on reasonable assumptions
• Must disclose data estimation approach and limitations

---

Implementation Timelines

Milestone	Date
CSRD in force	5 January 2023
ESRS published	22 December 2023
Large PIEs first report	FY 2024 → published 2025
Other large companies first report	FY 2025 → published 2026
Listed SMEs first report	FY 2026 → published 2027
Non-EU companies first report	FY 2028 → published 2029

Omnibus status (October 2026): everything is now law — scope: Directive (EU) 2026/470 in force (transposition due March 19, 2027; Germany still pending); content: Delegated Regulations (EU) 2026/1563 (revised ESRS, OJ Sept 21, in force Nov 10, 2026) and (EU) 2026/1560 (voluntary standard, in force Sept 24). Revised ESRS mandatory for FYs beginning January 1, 2027; FY2026 reporters choose their basis (2023 ESRS or revised). Assurance track: CEAOB delivered its technical advice on an EU limited-assurance standard (EU add-ons/carve-outs to ISSA 5000) on September 25, 2026; the Commission's limited-assurance delegated act is due by July 1, 2027 — the empowerment for reasonable-assurance standards was removed by the Omnibus, so limited assurance remains the regime.

CSRD vs. Other Frameworks

Aspect	CSRD/ESRS	GRI	TCFD	SASB
Mandatory?	Yes (EU law)	Voluntary	Voluntary (some jurisdictions mandatory)	Voluntary
Double materiality	Required	Impact materiality	Financial materiality	Financial materiality
Climate Scope 3	Required if material	Encouraged	Required	Sector-specific
Assurance	Legally required	Optional	Optional	Optional
Digital tagging	Required (XBRL)	None	None	None
ESRS alignment	Native	ESRS references GRI	ESRS incorporates TCFD	SASB maps to ESRS

GRI interoperability: ESRS 1 Appendix C maps ESRS to GRI; companies with GRI reports can identify gaps rather than start from scratch. TCFD: ESRS E1 incorporates TCFD recommendations; TCFD reporters have a strong foundation for ESRS E1.

Workflows

1. Scope Determination

1. Check entity type: EU company / non-EU company / SME
2. Apply size thresholds (employees + turnover + assets — 2-of-3)
3. Check listing status
4. Determine first mandatory reporting year
5. Check for PIE status (listed, bank, insurer)
6. Consider group reporting — subsidiaries covered by group CSRD report may be exempt

2. CSRD Gap Assessment

1. Confirm scope and first reporting year
2. Review current ESG/non-financial reporting (GRI, TCFD, CDP, SASB)
3. Conduct DMA to identify material ESRS topics
4. Map existing disclosures to mandatory ESRS datapoints
5. Identify data gaps — especially Scope 3, value chain, ESRS S1 pay gap
6. Assess governance gaps (sustainability in board oversight)
7. Evaluate assurance readiness
8. Produce gap table with priority and timeline

3. Transition Plan Drafting (ESRS E1)

Required elements per ESRS E1-1 and Art. 19a(2)(a):

• Decarbonisation targets (2030, 2050) aligned with 1.5°C
• Planned actions and resources by time horizon
• Financial planning: capex/opex/R&D for decarbonisation
• Carbon offsets role (limited)
• EU Taxonomy alignment targets
• Locked-in GHG assets

4. Value Chain Reporting Setup

1. Map tier-1 suppliers and key downstream channels
2. Identify material value chain topics from DMA
3. Assess data availability from key suppliers
4. Define data collection process (surveys, contracts, CDP)
5. Apply sector averages/proxies where direct data unavailable
6. Disclose methodology and estimation approach
