What CSDDD Changes
Voluntary supplier codes have often been limited to declarations and audits. CSDDD turns due diligence into a legally defined process: companies identify, assess, prioritise, prevent, mitigate, bring to an end or minimise adverse impacts, track effectiveness, and contribute to remedy where required. The Directive requires appropriate measures reasonably available in the circumstances, taking account of impact severity, the company's connection to the impact, and its ability to influence the business partner.
Which Companies Are Covered and Timing
Following Omnibus I, the general scope covers very large EU companies with at least 5,000 employees and at least EUR 1.5 billion in net worldwide turnover. For third-country companies, the key threshold is at least EUR 1.5 billion in net EU turnover. Figures may be assessed at the consolidated ultimate-parent level. Directive 2024/1760 was amended by Directives 2025/794 and 2026/470. Member States must adopt national rules by 26 July 2028 and apply them from 26 July 2029. Public reporting under Article 16 applies for financial years beginning on or after 1 January 2030. Because directives are transposed into national law, supervisory procedures and penalties may differ.
Risk-Based Approach and the Due-Diligence Cycle
Due diligence covers own operations, subsidiaries, and relevant business-partner relationships. Detailed assessment may focus primarily on direct business partners, but indirect tiers cannot be ignored where the company has plausible information about a potential or actual severe impact. The process: policy and accountability integration → identify and assess adverse impacts → prioritise → prevent potential impacts → bring actual impacts to an end or minimise → notification and grievance mechanisms → monitoring → public communication. Where the company caused or contributed to harm, remedy may include compensation, restoration, medical support, and guarantees of non-repetition.
Working with Suppliers and Grievance Mechanisms
A supplier code and contractual clauses are useful but do not by themselves demonstrate due diligence. Companies should examine whether purchasing practices create root causes — unrealistic lead times, constant price pressure, or abrupt volume changes. Measures may include training, technical assistance, longer contracts, shared financing of improvements, and industry initiatives. Disengagement should not be an automatic first response where it would worsen conditions for workers or communities. Grievance mechanisms must provide confidentiality, protection from retaliation, clear timelines, independence, and feedback. Recurring complaints can reveal systemic problems.
Climate Transition Plan and How to Prepare
CSDDD requires a climate-transition plan with implementation actions planned and taken. For CSRD reporters, information should be consistent with ESRS, financial planning, and capital expenditure. Preparation: confirm scope → map group, operations, major products, and chains of activities → gap analysis of policies and procurement → define risk owners, prioritisation methodology, escalation criteria, partner-support measures, remedy procedures, and monitoring. Preparation should involve legal, procurement, operations, ESG, HR, safety, and finance functions — not remain solely with the sustainability team.
CSDDD requires risk-based management of the most severe impacts on people and the environment, not endless questionnaire collection. A strong system combines mapping, prevention, purchasing-practice change, affected-stakeholder participation, monitoring, and remedy.
