CSDDD vs CSRD
CSDDD and CSRD are the two pillars of the EU's corporate sustainability framework — but they are fundamentally different in nature. CSRD requires disclosure. CSDDD requires action. Understanding how they interact, where they overlap, and where they diverge is essential for any large EU company managing both obligations simultaneously.
CSDDD and CSRD are the two pillars of the EU's corporate sustainability framework — but they are fundamentally different in nature. CSRD is a transparency regulation.
The fundamental difference — disclosure vs conduct
CSRD is a transparency regulation. It requires companies to identify their sustainability impacts, risks, and opportunities — and disclose them accurately using standardised ESRS formats. Compliance means accurate disclosure. A company that has terrible supply chain human rights practices but discloses them fully and accurately is CSRD-compliant.
CSDDD is a conduct regulation. It requires companies to actually prevent and remediate adverse human rights and environmental impacts in their value chains. Compliance means taking action — not just reporting on the situation. A company that discloses poor supplier labour standards but takes no action to address them is CSRD-compliant but CSDDD non-compliant.
This distinction has profound practical implications. CSRD compliance is primarily a reporting and data management challenge. CSDDD compliance is an operational challenge — it requires changing how you select suppliers, what you require of them contractually, how you monitor their performance, and what you do when violations are found.
For corporate strategy: the two regulations together create a coherent framework — CSRD creates the transparency that exposes problems, CSDDD creates the obligation to fix them. A company cannot hide behind disclosure to avoid action.
Where CSDDD and CSRD overlap — the efficiency opportunity
Despite their different natures, CSRD and CSDDD cover substantially the same ground in many areas — creating significant data and process overlap that smart companies will exploit.
Value chain mapping: CSRD ESRS S2 requires identification of material value chain worker risks. CSDDD requires mapping the value chain to identify adverse impact exposure. The same mapping exercise satisfies both.
Human rights due diligence: CSRD ESRS S2 requires disclosure of due diligence processes for value chain workers. CSDDD requires those processes to exist and be effective. Building one programme satisfies both — CSRD requires disclosure of it; CSDDD requires implementation of it.
Climate transition plan: CSRD ESRS E1-1 requires disclosure of a climate transition plan. CSDDD Article 22 requires adoption and implementation of a transition plan. One document, two regulatory purposes.
Governance disclosure: CSRD ESRS G1 requires anti-corruption and governance disclosures. CSDDD requires a due diligence policy approved at board level. The governance infrastructure disclosed under CSRD supports CSDDD compliance.
Grievance mechanisms: CSRD ESRS S1-4 and S2 require disclosure of grievance mechanisms for workers. CSDDD Article 14 mandates establishment of a complaints procedure. One mechanism, two regulatory requirements.
The efficiency strategy: build one integrated sustainability programme — map value chains, implement due diligence, establish grievance mechanisms, adopt a transition plan. Use CSRD reporting to disclose this programme. The same investment satisfies both regulations.
Where they diverge — the CSDDD-only obligations
Several CSDDD obligations go beyond what CSRD requires — these represent the incremental CSDDD compliance effort for companies already CSRD-compliant.
Active prevention obligation: CSDDD requires companies to take specific preventive measures — not just identify and disclose risks. Supplier contractual commitments, capacity building programmes, supplier audits, and where necessary suspension or termination of supplier relationships are CSDDD-specific obligations with no CSRD equivalent.
Remediation obligation: Where adverse impacts are occurring, CSDDD requires companies to bring them to an end and provide remedy to affected persons. CSRD requires disclosure of how impacts are managed — not remedy of them.
Complaints procedure: CSDDD Article 14 requires a formal complaints procedure accessible to affected persons and NGOs — not just to internal employees. CSRD grievance mechanism disclosure is internal-facing; CSDDD requires an external-facing mechanism for supply chain victims.
Civil liability: CSDDD Article 29 creates civil liability for due diligence failures — affected persons can sue in EU courts. CSRD has no equivalent civil liability provision.
Director pay linkage: CSDDD Article 22(4) requires linking director variable pay to transition plan delivery. CSRD discloses whether this linkage exists — CSDDD requires it to exist.
Frequently asked questions
If we are CSRD-compliant, how much additional effort does CSDDD require?
Significant but not starting from zero. CSRD-compliant companies have the data infrastructure, value chain mapping, and governance framework that CSDDD requires. The incremental CSDDD effort is primarily operational — moving from disclosure of due diligence to active implementation of it. Estimate 30–50% additional effort beyond CSRD for full CSDDD compliance.
Can a company be CSRD-compliant but CSDDD non-compliant?
Yes — and this is the key regulatory risk many companies overlook. CSRD compliance requires accurate disclosure of sustainability practices. CSDDD compliance requires those practices to meet a minimum standard of due diligence effectiveness. A company that transparently discloses inadequate supply chain practices is CSRD-compliant but CSDDD non-compliant.
Which regulation applies to more companies — CSRD or CSDDD?
CSRD — significantly. Post-Omnibus, CSRD applies to companies with 1,000+ employees AND €450M+ turnover — approximately 5,000–10,000 companies. CSDDD Wave 3 (the broadest) applies to companies with 1,000+ employees AND €450M+ turnover from 2029 — a similar population. But Wave 1 CSDDD (2027) is much narrower: 5,000+ employees AND €1.5B+ turnover — approximately 1,000 companies.
