The EU Corporate Sustainability Due Diligence Directive (CSDDD) entered into force on 25 July 2024 and is being implemented through national transposition and supervisory enforcement. In-scope companies face administrative supervision, injunctive measures, and fines that can reach 3% of worldwide net turnover, alongside national civil liability for harm caused by due diligence failures.
CSDDD Corporate Sustainability Due Diligence (EU)
The EU Corporate Sustainability Due Diligence Directive (Directive 2024/1760) entered into force on 25 July 2024 and creates a mandatory due diligence regime for in-scope companies across the EU market.[1][13] It is designed to require businesses to identify, prevent, mitigate, end, and remedy adverse human rights and environmental impacts linked to their own operations, subsidiaries, and relevant business relationships.[8][11]
Enforcement status
The directive is now in force, but enforcement depends on national transposition into member-state law and the designation of supervisory authorities.[1][8] The European Commission has stated that member states must transpose the directive by 26 July 2026, with rules beginning to apply to companies one year later, on 26 July 2027, for the first wave of in-scope entities.[8] Enforcement will be coordinated through a European Network of Supervisory Authorities, while day-to-day supervision sits with national authorities.[1][8]
Penalty amounts
The directive requires member states to provide effective, proportionate, and dissuasive penalties, including fines.[1][8] The Commission states that the maximum limit for pecuniary penalties is 3% of the company’s net worldwide turnover for the most serious violations.[1] Other sources discussing the directive’s final compromise note that the exact penalty design is left to member states, but the turnover cap is the key EU-level ceiling.[3][12]
Compliance requirements
In-scope companies must build a due diligence system that covers their own activities, subsidiaries, and relevant business partners in the chain of activities.[8][11] Core requirements include: mapping actual and potential adverse impacts, taking preventive and corrective action, monitoring effectiveness, maintaining complaints mechanisms, and publishing a climate transition plan where required.[8][14] Supervisory authorities can request information, investigate on their own initiative or on the basis of substantiated concerns, order companies to comply, and impose interim measures or sanctions.[5][7][14]
Civil liability and claims exposure
The directive also creates a civil liability pathway under national law where a company’s failure to meet due diligence duties causes damage and the conduct is intentional or negligent.[1][11] Affected persons are entitled to full compensation where liability is established under applicable national rules.[1]
For trade compliance teams, the practical risk is that CSDDD is becoming a board-level supply chain governance obligation rather than a purely ESG reporting issue. Companies with complex sourcing, outsourcing, or distribution networks should treat supplier screening, contractual controls, escalation procedures, and evidence retention as immediate compliance priorities.
