EU CSDDD Human Rights and Environmental Due Diligence Implementation Process and Value Chain Engagement Requirements
ENFORCEMENT TIMELINE
Directive entered into force on July 25, 2024 (as amended, national transposition measures apply from July 26, 2029)
Overview
This card focuses on the concrete implementation requirements for the human rights and environmental due diligence (DD) process at the core of the EU Corporate Sustainability Due Diligence Directive (CSDDD: Directive (EU) 2024/1760).
CSDDD codifies the six-step due diligence process defined in the OECD Guidelines for Responsible Business Conduct as a binding legal obligation. Covered companies must identify, prioritize, and address adverse human rights impacts (such as child labor, unfair labor practices, and unpaid wages) and environmental harms (such as unlawful discharge, release of hazardous substances, and deforestation) across their entire chain of activities — not only their own operations, but also subsidiaries and both upstream (raw material sourcing and manufacturing) and downstream (transport and storage) activities. Companies are also required to establish grievance mechanisms. In identifying and assessing adverse impacts, they may make use of independent reports and industry or multi-stakeholder initiatives, among other resources.

Business Impact
Companies subject to CSDDD must establish a full governance structure and six-step due diligence operation — from setting sustainability policy, through identifying and assessing adverse impacts, drafting corrective action plans (CAPs), monitoring their effectiveness, operating grievance channels, and disclosing information. For direct and indirect suppliers, companies will need to roll out supply chain codes of conduct and contractual clauses requiring compliance with human rights and environmental standards. The European Commission is to issue guidance on voluntary model contractual clauses by 26 July 2027. Using third-party verification or contractual clauses does not rule out liability under national law.
At the same time, CSDDD prohibits large companies from unilaterally shifting costs or burdens onto their suppliers, and instead obligates them to provide financial, technical, and training support to small and mid-sized suppliers.
