CSRD Simplified: A Practical Guide for Businesses
The Corporate Sustainability Reporting Directive is the most significant sustainability reporting regulation in EU history. This guide cuts through the complexity to explain what you actually need to do.
What is the CSRD?
The Corporate Sustainability Reporting Directive (CSRD) entered into force in January 2023, replacing the Non-Financial Reporting Directive (NFRD). It dramatically expands the scope of mandatory sustainability reporting in the EU ā from approximately 11,000 companies under NFRD to an estimated 50,000+ under CSRD.
CSRD requires companies to report against the European Sustainability Reporting Standards (ESRS) ā a detailed set of standards covering environmental, social, and governance topics, developed by EFRAG.
Who is in scope ā and when?
| Company Type | Reporting Start |
|---|---|
| Large listed companies already under NFRD (>500 employees) | 2025 (FY 2024 data) |
| Large EU companies (>250 employees or ā¬40M revenue) | 2026 (FY 2025 data) |
| Listed SMEs, small & non-complex credit institutions | 2027 (FY 2026 data) |
| Non-EU companies with significant EU revenue (>ā¬150M) | 2029 (FY 2028 data) |
The ESRS Standards ā What You Need to Disclose
ESRS disclosures cover three layers:
- ESRS 1: General requirements (the framework for applying all other standards)
- ESRS 2: General disclosures ā mandatory for all in-scope companies
- ESRS E1āE5: Environmental topics (Climate, Pollution, Water, Biodiversity, Resources)
- ESRS S1āS4: Social topics (Workforce, Value Chain Workers, Communities, Consumers)
- ESRS G1: Governance (Business Conduct)
Disclosures for ESRS E1āS4 and G1 are subject to the double materiality assessment ā meaning you only disclose the topics that are material to your organisation.
Double Materiality: The Central Concept
CSRD's defining feature is the double materiality approach. You must assess each topic from two perspectives:
Impact Materiality
Does your organisation have significant actual or potential impacts on people or the environment? (Inside-out perspective)
Financial Materiality
Do sustainability risks or opportunities significantly affect your financial position or performance? (Outside-in perspective)
A topic is material if it passes either test ā or both. The process must be documented and auditable.
5 Steps to Get Started
- 1
Confirm your scope
Check if and when your company is in scope. Large subsidiaries of in-scope groups may also need to report.
- 2
Conduct a gap analysis
Compare your current sustainability disclosures against ESRS requirements. Identify what is missing.
- 3
Run a double materiality assessment
This is the foundation of your CSRD report. It determines which ESRS topics and disclosures apply to you.
- 4
Build your data infrastructure
Identify what data you need for each material topic. Many companies need to redesign their data collection processes.
- 5
Draft and assure
Write your sustainability statement, integrate it into your management report, and engage an assurance provider.
Key Risks of Non-Compliance
- Financial penalties imposed by member state regulators
- Reputational damage with investors, customers, and employees
- Exclusion from procurement and supply chain opportunities
- Investor divestment from non-compliant companies
