What Is CSDDD?
The Corporate Sustainability Due Diligence Directive (CSDDD, also known as CS3D), adopted by the EU in 2024, requires large companies to identify, prevent, mitigate, and account for adverse human rights and environmental impacts in their operations and value chains. It builds on existing national legislation (Germany's LkSG, France's Duty of Vigilance) but is broader in scope and introduces EU-wide civil liability.
CSDDD represents a fundamental shift in corporate accountability — companies are legally responsible not just for their own impacts but for adverse impacts throughout their chains of activities.
Who It Applies To
Phase-in based on size:
| Phase | Year | Employees | Turnover |
|---|---|---|---|
| Phase 1 | 2027 | 5,000+ | €1.5B+ |
| Phase 2 | 2028 | 3,000+ | €900M+ |
| Phase 3 | 2029 | 1,000+ | €450M+ |
Non-EU companies: Companies from outside the EU with net turnover exceeding the relevant thresholds generated in the EU are also covered from 2029.
Key Requirements
Due diligence obligations (six-step process):
-
Integrate due diligence into policies: Adopt and implement a due diligence policy describing the company's approach, code of conduct, and processes
-
Identify and assess impacts: Map actual and potential adverse human rights and environmental impacts in own operations, subsidiaries, and the chain of activities (business partners)
-
Prevent, mitigate, and end impacts: Take appropriate measures to prevent potential impacts and end or minimize actual impacts. This includes developing corrective action plans, seeking contractual assurances, making investments, and providing targeted support to business partners
-
Monitor effectiveness: Track due diligence implementation and effectiveness through qualitative and quantitative indicators
-
Communicate: Publicly report on due diligence through annual statements
-
Provide remediation: Provide remediation where the company has caused or contributed to adverse impacts, including financial compensation, rehabilitation, and engagement with affected stakeholders
Climate transition plan: Companies in scope must adopt and implement a transition plan for climate change mitigation aligned with the Paris Agreement's 1.5°C target, including emission reduction targets, decarbonization levers, and planned investments.
Covered impacts:
- Human rights impacts as defined in international instruments (UN Guiding Principles, ILO conventions, international human rights law)
- Environmental impacts including climate change, biodiversity loss, pollution, water degradation, and deforestation
Timeline
- 2024: CSDDD adopted
- 2026: Member states must transpose into national law
- 2027: Phase 1 companies begin compliance
- 2028: Phase 2 companies begin
- 2029: Phase 3 companies and non-EU companies begin
- Ongoing: Regular review and potential expansion of scope
Civil Liability
CSDDD introduces a civil liability regime:
- Companies are liable for damages caused by failure to comply with due diligence obligations
- Affected persons (including individuals and communities anywhere in the world) can bring claims before courts in EU member states
- Trade unions and NGOs can bring actions on behalf of affected persons
- Limitation period of at least 5 years from when the damage occurred
- Courts can order companies to take appropriate measures to cease the infringement
This creates significantly more legal exposure than existing national laws like Germany's LkSG.
